An Epic Odyssey: Celebrating Warren Washington (1936–2024)

By Anjuli S. Bamzai, AMS President

Dr. Warren Washington passed away last month. The American Meteorological Society was lucky to benefit from a career’s worth of attention from this exceptional individual — a trailblazer in climate modeling, NCAR Distinguished Scholar, advisor to five U.S. presidents, National Science Board chair, and longtime leader of the AMS community. He was among the first to develop and use the pioneering atmospheric general circulation models that underlie our current understanding of climate change, and his research contributed to the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report that received the Nobel Peace Prize in 2007.

Warren joined AMS as an undergraduate student and was actively engaged with the Society his entire career. He served as our AMS President in 1994, our 75th anniversary year. He played a key role in advancing initiatives to enhance diversity in the field, including as a scholarship donor and co-founder of the Board on Women and Minorities. He was named an Honorary Member, and received several prestigious AMS awards. He was a mentor, beloved colleague, and friend to many of us, myself included.

Elucidating the Future Climate

Warren was born in Portland, Oregon. His parents placed a high value on education despite the “hostility” his mother faced as a nurse when studying at the University of Oregon and the struggles his Talladega College-educated father faced during the Great Depression. Warren earned his undergraduate degree in physics and his master’s degree in meteorology at Oregon State University. He went on to become the second ever African American to earn a doctorate in the atmospheric sciences, which he received from Penn State University in 1964.

<<The cover of Dr. Warren Washington’s autobiography shows a 1930 panoramic photograph (in three parts) of the Portland, Oregon Bethel African Methodist Episcopal Church and its congregation, which represented about 5% of Oregon’s Black population at the time. Warren’s maternal grandfather, Wirt Morton Sr., is fifth from the right in the bottom segment; Warren’s mother, Dorothy Morton, is in the top segment (to the left of the church door and immediately to the left of the man holding a hat in his hand).

In 1963, Warren joined the NSF National Center for Atmospheric Research (NCAR) as a research scientist. He would remain connected with NCAR for over six decades. He was a Distinguished Scholar there at the time of his passing.

In the 1960s, he worked with his colleague Dr. Akira Kasahara to develop one of the first computer models of the atmosphere. His team at NCAR used those models to enhance our understanding of the role of natural processes as well as human activities in the coupled Earth system — over time incorporating oceans, sea ice, surface hydrology, and more into their simulations. This research would go on to inform innumerable contributions in climate science, including the IPCC’s Nobel Peace Prize-winning work.

In 1986, Warren co-authored the book, An Introduction to Three-Dimensional Climate Modeling, with Claire Parkinson. It provided an introduction to the development of three-dimensional climate models and their applications for simulating aspects of the current climate system, from ENSO to the effects of increasing greenhouse gas concentrations on future climate.

I met Warren on my first visit to NCAR back in the 1990s, and then interacted more closely with him when I was program manager of the climate modeling program at the U.S. Department of Energy and he was serving on the DOE Biological and Environmental Research Advisory Committee (BERAC). We also worked closely on an  international workshop, “Challenges in Climate Change Science and the Role of Computing at the Extreme Scale,” which Warren chaired in 2008. In looking back at the workshop’s themes — which focused on computational issues associated with model development, simulations and assessment, decadal predictability, natural variability and prediction — I am struck by what a visionary Warren was to identify two decades ago some of the vexing issues in climate science that we are still addressing today!

A Decorated Life

During the span of his illustrious career, Warren was on numerous federal advisory committees and commissions. He served on the National Science Board (1994–2006); initially as a member and then as the Chair starting in 2002. In 2002, he was elected to the National Academy of Engineering “for pioneering the development of coupled climate models, their use on parallel supercomputing architectures, and their interpretation.” In 2003, he was elected to the American Philosophical Society.

In 1999, Warren received the Charles Anderson Award from the AMS for “pioneering efforts as a mentor and passionate supporter of individuals, educational programs, and outreach initiatives designed to foster a diverse population of atmospheric scientists. Dr. Charles E. Anderson (1919-1994) was a former Tuskegee Airman and the first African American to receive a PhD in meteorology.

In 2006, Warren became an Honorary Member of the AMS. In his acceptance speech, for which he received a standing ovation, he advised early career scientists to find personal growth and leadership by taking part in the broader aspects of their field. He also stated that “Scientists should be free to tell the public, media, and policy makers the results of their research. Of course, there is always the need to make sure not to confuse the public, so individual responsibility is important.” He ended his speech by pointing out that scientific debate should be settled at scientific society meetings.

At the following AMS Annual Meeting, he received the Charles Franklin Brooks Award for Outstanding Service to the Society, and a couple of years later, he shared the 2009 AMS Jule G. Charney Medal with his longtime colleague and collaborator Jerry Meehl.

In 2010, Warren was also one of the ten eminent researchers to be awarded the National Medal of Science by President Barack Obama, “for his development and use of global climate models to understand climate and explain the role of human activities and natural processes in the Earth’s climate system and for his work to support a diverse science and engineering workforce.”

Warren was a Distinguished Alumnus of Penn State and in 2019, Penn State named a building in his honor at its campus Innovation Park site.

A Legacy of Empowerment

Warren was instrumental in establishing AMS’s Board on Women and Minorities, now known as AMS BRAID. He and his wife, Mary, also established an AMS undergraduate scholarship to provide support to underrepresented students. Through their generosity, several who otherwise might not have attended the AMS Annual Meeting have been able to do so.

In early 2020, the AMS set up The Warren Washington Research and Leadership Medal to be awarded to individuals recognized for the combination of highly significant research and distinguished scientific leadership in the atmospheric and related sciences.

Warren was a pioneer and true giant in our community. Those of us who were fortunate to interact with him benefited from his sage counsel, vision, and sharp intellect. No question was mundane enough that it didn’t get a deliberate, candid yet considerate response from him. He helped so many realize their full potential to excel. What a great scientist, and a great humanist! His legacy lives on through those he supported, mentored, and inspired.

Dr. Warren Washington was the epitome of a true leader.

Native American Heritage Month Spotlight: Robbie Hood

Robbie Hood

November is National Native American Heritage Month. In this post, we spotlight the exceptional career of one of our Native American community members: Robbie Hood.

Hood is an atmospheric scientist with over 30 years of experience at the National Aeronautics and Space Administration and the National Oceanic and Atmospheric Administration. She is a member of the Cherokee Nation of Oklahoma.

Can you tell us a few highlights of your current or most recent work?

I am a Cherokee meteorologist who worked with NASA and NOAA for a combined total of 30 years. Now in retirement, I am collaborating with NCAR personnel to explore how low-cost 3-D printed weather stations could be used by Indigenous communities for student training and tribal decision-making. I have also been collaborating with the Rising Voices Center for Indigenous and Earth Sciences to plan the program for the 2025 AMS Heather Lazrus Symposium to be held during the 105th AMS Annual Meeting in New Orleans. In this symposium, I will be moderating a panel discussion focused on cultivating tribal and community partnerships within the weather, water, and climate enterprise.

What was an important moment in your early career?

I started my meteorological career as scientific programmer, but I was given an opportunity to step out of my comfort zone at NASA. I became the project scientist for a new passive microwave aircraft instrument that could observe precipitation within thunderstorms and hurricanes. This move gave me the opportunity to work with and, eventually, lead teams of renowned scientists, engineers, and pilots during large international weather field experiments that were conducted in places like Australia, Brazil, Costa Rica, Cape Verde, and the Marshall Islands. Along the way, I got to fly through four different hurricanes, all because I initially stepped out of my comfort zone.

What is something you’re proud of professionally?

My experience leading weather field experiments led me to become the manager of a NOAA program to test the potential benefit of drones and remotely piloted aircraft for operational application. In this role, I was able to organize and fund a multi-million-dollar field experiment to test, for the very first time, the capabilities of a high-altitude Global Hawk remotely piloted aircraft that was controlled from a central command center in Virginia to fly over and observe the characteristics of hurricanes and tropical storms in the Atlantic Ocean and Gulf of Mexico. During these missions, relevant data were successfully sent in near-real time to meteorologists at the National Hurricane Center to assist in their forecasts. Later research studying the impact of Global Hawk data assimilated into weather prediction models demonstrated positive results.

Are there ways in which your Native heritage has influenced or enriched your career?

I credit my Cherokee mother for teaching me to listen closely to how people tell their stories and pay attention to their feelings and expressions as they talk. She thought this would help me better understand who they are and how things looked from their point of view. These skills have helped me build good working relationships and strong collaborations throughout my career.

What’s the Future of Weather Decision-Making?

A 2024 AMS Summer Community Meeting highlight

Matt Corey

The AMS Summer Community Meeting drew exceptional attendance and engagement this year as people across sectors helped inform an upcoming report on the Weather Enterprise. The AMS Weather Enterprise Study will provide a comprehensive picture of the shifting landscape of weather-related fields to inform our joint future. At the 2024 SCM, working groups discussed what they’d found about key issues facing the enterprise, and asked for feedback from the community.

Here are a few takeaways from the Decision Support Services working group, as reported by Matt Corey (pictured at left) of Microsoft Weather. Decision support services (DSS) help stakeholders make weather-related decisions that are informed by the best available knowledge across fields. They are crucial for emergency managers and many other decision makers, as well as members of the public.

How has the decision support landscape shifted in the last decade or so?

Stakeholders for DSS range from an emergency manager making critical decisions about an entire community to an everyday citizen making a decision for themselves or their family. For decision support services, the last two decades have seen an abundance of technology changes which have allowed stakeholders easier access to information. However, this can be both a benefit and a challenge, as misinformation has also become more readily available.

What were the main themes that came out of your working group’s discussions?

The themes that emerged for us included:

  • The different sectors of the Weather Enterprise have become coupled, with less well-defined boundaries when it comes to providing decision support.
  • New players are entering the enterprise, with growing AI and novel ideas.
  • Developing and maintaining the necessary workforce is a concern.
  • There are increased opportunities for translating forecasts into easily understood language in order to support decisions.
  • There is a need for increased funding for quality observational datasets for many applications, especially in AI.
  • In a complex, misinformation-rich environment, there is still room for all sectors to tailor communications to stakeholders, but there is also concern about maintaining consistency in order to maintain trust.
  • Embracing user centric design to understand stakeholder concerns, technical levels, and understanding is important, including the use of probabilistic information.  Example:  “There is an 80% chance the flooding will happen this afternoon.”

What are the main challenges you have identified?

In our group, the discussion continues to be about who should be providing decision support services. As the NWS gets more involved in DSS, one concern is for increased friction from some private sector entities. Another key point is that DSS is not limited to a specific stakeholder type. DSS is important to all citizens who need to make decisions involving weather every day, thus there is a shared dimension and need for responsible and clear messaging to all stakeholders (including the tactical use of probabilistic information). 

A final recurring theme is around the workforce itself. Forecasters need to be taught communication skills, and social science is critical in helping to understand the needs and problems to be solved for the end users. With the focus shifting to newer tools including AI-infused capabilities, there is a concern that the new workforce will lose the necessary skills critical in conveying adequate decision support services.

What preliminary/tentative recommendations, solutions, or future directions have you discussed?

Some of the recommendations we’re working with right now focus on:

  • Integration of weather, water, and climate information with socioeconomic and biosphere information for earth system forecasts.
  • Cross-sector support of ecological forecasts and environmental early warning systems (for example, warnings of fishing industry impacts due to warmer water) to benefit society and facilitate impact-based action.
  • Improved communication about weather impacts, especially in a changing climate, using common terms and learnings based on stakeholder’s decision needs.
  • Embracing AI as a way to increase the velocity of forecasts, integrate probabilistic information into forecasts, and increase efficiency for both short-term services like nowcasting and long-term climate solutions for all.
  • Helping meteorologists to become the communicators that they should be. Leveraging AI solutions and tools to help make them more efficient at helping stakeholders with their decisions.
  • Expanding opportunities for smaller businesses/individuals to obtain specialized DSS.
  • Increased public awareness of changing weather patterns stimulating the need for better accuracy, earlier warnings, and long-range projections.
  • The need to smartly integrate probabilistic information to help stakeholders better understand forecasts and limitations.

About the AMS Summer Community Meeting

The AMS Summer Community Meeting (SCM) is a special time for professionals from academia, industry, government, and NGOs to come together to discuss broader strategic priorities, identify challenges to be addressed and opportunities to collaborate, and share points of view on pressing topics. The SCM provides a unique, informal setting for constructive deliberation of current issues and development of a shared vision for the future. The 2024 Summer Community Meeting took place August 5-6 in Washington, DC, and focused special attention on the Weather Enterprise, with opportunities for the entire community to learn about, discuss, debate, and extend some of the preliminary findings coming from the AMS Weather Enterprise Study.

Renewable Energy Needs the Weather Enterprise: A call to action

Justin Sharp

The “Transition to Carbon-Free Energy Generation” Presidential Session at the AMS 104th Annual Meeting discussed the status of–and barriers to–the U.S. transition to renewable energy. During that panel, I and several other speakers discussed how the weather enterprise will be key to this effort. Meteorological expertise is a keystone of power systems with large shares of renewable energy.

Weather Drives a Vastly More Complex Electric System 

Existing electric systems are some of the largest and most complex machines humankind has ever built, with every component linked and synchronized. Electricity consumption is increasing rapidly as sectors currently powered by fossil fuels switch to electric power, and demands from data centers, AI, and cypto-mining escalate. Many of these new loads, such as electric vehicles and indoor heating/cooling/ventilation systems, are affected by weather, especially temperature. At the same time, extreme weather events continue to cause infrastructure outages, a trend likely to increase with climate change.

Amping up solar and wind power means electricity generation is affected by additional weather variables: wind speed, clouds, and aerosols. Thus, weather-dependent generators, sited across broad geographic areas, produce complex interactions that can have large impacts that were never previously imagined.

Planning and operating such an electric system, day and night, through heat and cold, sun and cloud, wind and calm, with increasing amounts of weather dependent load, using large numbers of wind and solar generators and energy-limited storage devices, is an unprecedented challenge for the sector. 

Better Data for Better Grids

Our ability to forecast renewable energy generation is improving rapidly, and better weather forecasts can reduce uncertainty in our estimates of future generation, easing the integration of renewable energy into grid operations. However, by themselves, even perfect forecasts cannot solve the problem of variability and shortfalls in renewable energy generation across the year. Better historical weather data (and best practices for their use) are vital to plan and build electric systems that can most effectively meet our highly variable energy demand, using diverse power sources and energy storage to ensure reliability across environmental and grid conditions.

Right now, the power sector is blind to a lot of key challenges, with power system planners often relying on weather data that is less certain and more limited than they believe it is. For example, gridded data from numerical weather prediction models are often utilized in planning tools without validation or uncertainty quantification and as if they have observational quality. This can result in important risks being missed. For instance, cold days lead to high electric demand and an increasing risk of infrastructure outages. Such critical days often occur in conjunction with strong inversions; frequently the combination of model resolution and/or parameterizations does not properly handle these inversions, resulting in over-estimates of wind and temperature, and under-estimates in clouds and fog. Issues like these could result in under- or over-building infrastructure, potentially leading to reliability concerns or incurring unnecessary costs.

Building a Weather-Data Infrastructure

Just as meteorologists employ models to diagnose and forecast atmospheric phenomena, electric system specialists utilize power system models to optimally plan and operate the grid. As electric grids evolve to include large amounts of renewable generation and energy storage, ensuring reliable, affordable electric power requires, a) improvement of these models to fully consider the uncertainty inherent in the weather and b) best-in-class, fit-for-purpose weather and climate information to inform the models.

Increasingly detailed records of past weather conditions for large regions and long time histories are needed — yet they typically do not exist as observations and thus must be synthesized. Comprehensive validation of such model data is also essential, along with user education and data curation to ensure that stakeholders appropriately apply weather intelligence in their downstream analyses. 

Assessing, validating, and hopefully bias-correcting weather model estimates requires large quantities of ground-truth weather data. The rapid buildout of wind and solar facilities is producing such a data network, but unfortunately, there is often significant resistance from owners to sharing this data. There’s hope though; the Electric Reliability Council of Texas (ERCOT) now mandates that all renewable generators provide their power and meteorological data to the public. We need to see similar approaches elsewhere, as soon as possible. 

You can learn more about all these issues in an ESIG report I co-authored. In summary, two incredibly complex fields — the electrical grid and atmospheric sciences — are becoming increasingly intertwined. There is a need to work together across sectors to define the requirements for optimal meteorological support for ongoing planning and operation of evolving power grids, and to develop an operational framework for producing, disseminating, and ensuring appropriate use of  this intelligence. EPRI and other organizations are working to convene stakeholders to respond to this urgent need and I encourage interested parties (including data users, data producers, and observational data owners) to contact me at EPRI. Only by working together across sectors can we create the reliable and affordable carbon-free grids needed to power the economy while ensuring a livable future for our planet.

Tornado Risks: Perceptions and Realities

A session spotlight from the 31st Conference on Severe Local Storms

By Katie Pflaumer, AMS Staff

The session “Perception and Risk Associated with Severe Weather” at the 31st Conference on Severe Local Storms highlighted the interactions between severe weather and societal impacts. Here are a few takeaways.

Tornado impacts are increasing across the United States–despite variation in where tornadoes hit. A presentation by Stephen Strader (Villanova University) highlighted the importance of considering all factors to understand tornado impacts, not just climate. Using 40 years of observational data, plus a statistical model depicting changes in societal factors, researchers found that increased housing and population growth in tornado-prone areas is a key driver of increased tornado damage/human risk. 

While the number of days with tornadoes is trending down in the U.S. Southern Plains and trending upward in the mid-South; the likelihood of tornado damage has increased in both regions due to increased human occupation. However, the combination of tornado increases with population growth and spread has tripled tornado impact potential in the mid-South since 1980, surpassing the Southern Plains. Strader noted that stricter enforcement of building codes, investments in tornado shelters and safe rooms, and public education could help mitigate tornado damages–if scientists can get across the message that human factors matter.


“We have to get away from this idea that climate change is a cause of a disaster … climate change is a contributor to a disaster, not a cause. [Disaster] is inherently linked to societal factors. … With environmental changes and exposure changes/housing growth, you see an increasingly disaster-prone society.”

—Stephen Strader

Changing Societal Vulnerability and Exposure.” (Poster presented at 31st Conference on Severe Local Storms, October 21.) Originally from Strader et al. (2024), “Changes in tornado risk and societal vulnerability leading to greater tornado impact potential.” NPJ Natural Hazards, 19 June. https://doi.org/10.1038/s44304-024-00019-6

Wireless Emergency Alerts are critical—and confusing—for Spanish speakers in the U.S. Southeast. A study presented by Joseph Trujillo-Falcón (University of Illinois) found that Spanish-language wireless emergency alerts (WEAs, phone notifications about severe weather) from the National Weather Service are crucial safety tools. For some tornado survivors in Kentucky, for example, the WEA had been their only trigger to get to safety. In-depth conversations with 27 Spanish speakers from across the U.S. found that WEAs were highly respected and useful, yet needed some redesign to avoid confusion. For example, the Spanish translation of the NWS acronym (SNM) called to mind medical conditions or kink. The word “proyectiles” (projectiles), used to warn about airborne debris, evoked war zone imagery rather than weather. Using the word “aviso” for “warning” struck many as less urgent than the term “alerta.” In addition, 360-word warnings (versus those of 90 words or less) helped readers better understand what was going on and what to do in response. This was especially important for people who hadn’t encountered a tornado in their country of origin. Direct links to information and instructions on how and where to shelter were also seen as key, especially in areas with many mobile or manufactured homes.

“The information source that I take most seriously as a recently arrived immigrant are WEAs. Since everyone gets it at the same time, if one ignores it, the other reads it.”

People want different forecast information as a threat evolves. A study presented by Makenzie Krocak (National Severe Storms Laboratory) analyzed data from the Severe Weather and Society survey to determine what information members of the public want and need at different times in relation to weather threats. They found that respondents’ priorities changed over time. In longer time frames (e.g., three days in advance) survey respondents overwhelmingly ranked location information and event probability as the most valuable information; people wanted to know, ‘Should I prepare for severe weather to occur in my area?’ A day to an hour in advance, people wanted to know about the timing of the event, as well as its potential severity. In the warning time frame (60 minutes or less) their desire for information about potential impacts and necessary protective actions increased.

For additional insight, the researchers painstakingly categorized, geo-located, and analyzed 9000+ social media comments from the National Weather Service Facebook and Twitter/X accounts before and after severe weather events. A poster presented by undergraduate student Emily Allen (University of Louisiana Monroe) delved into this side of the equation.

Emily Allen with her poster, “Assessing Public Information Needs Leading Up to Severe Weather Events.” (E.A. Allen and M. Krocak, 2024)

Three days out from an event, commenters largely asked about the chance of an event happening, but for nearer time frames, location became the dominant question—i.e., ‘Will this hit my specific area?’ Krocak emphasized the need to include very clear landmarks in warning graphics to help people find their location. She also noted that certain groups still require information about protective actions to take—especially those with the least experience dealing with a particular hazard.

Making severe weather products usable and understandable. Two presentations dealt with public perceptions of evolving probabilistic weather forecast information—that is, communicating changes in severe weather risks across time and geography. 

Christopher Wirz (NSF NCAR) presented preliminary results of a study about public perceptions of evolving probabilistic tornado forecasts and warnings. On average, respondents’ sense of risk was about the same as for a deterministic (e.g., warning vs no-warning) forecast; most were likely to be on high alert during a tornado warning in any case, and not underestimate their risk. However, there were differences in how participants responded based on where they were located relative to a given warning polygon. For example, some felt they were in more danger if they were ‘in front’ of the warning polygon, despite the graphics showing equal tornado risk in other directions. Warn-on forecasts—alerts issued when a significant risk is predicted, often long before a tornado is detected by radar—were seen as less actionable by some, but others appreciated knowing to ‘keep an eye out.’ Overall, the study found that members of the public don’t take probabilistic information at face value—rather, they interpret it based on context, including existing local knowledge and other warning products they encounter. In addition, for half of the respondents, level of trust in a forecast didn’t change when they received more/updated information, because trust was instead based on how much they trusted the source of the forecast.

Kristin Calhoun (NOAA National Severe Storms Laboratory) presented about new products and communications that are in development to help NWS forecasters and emergency managers use storm-based probabilistic hazard information (PHI) in the severe weather watch-warning timeframe. These included PHI tools layered with threats-in-motion (TIM) information, in which warning polygons are moved (and removed) with the motion of the storm, helping downstream areas prepare sooner and allowing those for whom danger has passed to redeploy their resources more strategically; potential new protocols for the NOAA/NWS Storm Prediction Center, rather than local weather forecast offices, to add or remove an area from a watch/warning once the threat has passed; a blended PHI plus warn-on forecast product that can help emergency managers plan better by seeing storms in motion along with trends in likelihood and potential impact; and a new product based on SPC’s ‘Mesoscale Discussions,’ created by local NWS forecasters and called ‘Local Discussions,’ with an increased focus on potential impacts, timing, and location of hazards versus highly technical information.

Social pressure may impact campus tornado safety. Alicia Klees (University of Illinois at Urbana-Champaign) presented work conducted largely by undergraduate student Kyla Wolski that has implications for student safety. The University of Illinois’s Illini-Alert system warns students when tornado threats are approaching; most students are aware of the alerts, and most have experienced a tornado warning before. Students were asked in a survey what they would do if they were in a vulnerable location—such as a fourth-floor classroom with glass windows—and received a tornado warning. 75% said they would change their location to seek shelter. However, when a hypothetical professor kept teaching through a tornado warning (as some faculty reportedly did during the last real tornado warning on campus), 22% of students who had planned to seek shelter said they would probably stay in class. These students said they trusted the professor’s judgment—yet professors do not receive extensive formal training on tornado safety. Klees recalled an anecdote from a student in which one faculty member remarked, “I don’t hear the sirens anymore, so it’s fine.”

In addition, most students did not view tornadoes as a major risk, and most were unaware that tornadoes could happen at any time of year. Klees identified future collaborations with Emergency Management to survey faculty and TAs on tornado warning response, with the goal of keeping students safe.

Can Decarbonizing the Electric Grid Help Avert Climate Catastrophe?

A Presidential Session Spotlight from the AMS 104th Annual Meeting

By Katie Pflaumer, AMS Staff

Significantly reducing greenhouse gas emissions requires transitioning primarily to carbon-free sources for energy generation, but many challenges stand in the way. What are these challenges, and how can the weather, water, and climate sector help meet them?

A Presidential Session at the 104th AMS Annual Meeting addressed those questions with panelists Debbie Lew (Executive Director at ESIG, the Energy Systems Integration Group), Alexander “Sandy” MacDonald (former AMS President and former director of the NOAA Earth Systems Research Laboratory), Aidan Tuohy (Director of Transmission Operations and Planning at EPRI, the Electric Power Research Institute), and Justin Sharp (then Owner and Principal of Sharply Focused, now Technical Leader in the Transmission and Operations Planning team at EPRI). Here are some key points that arose from the session, titled, “Transition to Carbon-Free Energy Generation,” introduced by NSF NCAR’s Jared Lee, and moderated by MESO, Inc.’s John Zack.

Key Points

  • Decarbonizing the electric grid is key to reducing U.S. greenhouse gas emissions.
  • Wind and solar are now the cheapest forms of energy generation; adoption is increasing, but not fast enough to catch up with the likely growth in demand. 
  • Energy demand is rapidly increasing, driven by the expansion of data centers, AI applications, crypto mining, and the electrification of transportation and heating. Hydrogen production might greatly increase future loads. 
  • “Massive buildouts” of both renewable energy plants AND transmission infrastructure are required to reduce emissions. 
  • A reliable and affordable power system with large shares of wind and solar generation requires accurate historical weather information to inform infrastructure buildout, and accurate forecasts to support operations. 
  • To avoid expensive infrastructure that’s only used during peak times, electricity pricing must incentivize consumers to avoid excessive use during periods of high demand. This requires accurate weather forecasting. 
  • Connecting the three main national grids together into a “supergrid” could improve transmission and grid flexibility, significantly reducing emissions.

The need for carbon-free energy is urgent

Greenhouse gas emissions are still increasing sharply. In response, global temperatures are rising faster than even the most pessimistic models would have predicted a few decades ago, noted Lee in his introductory remarks to the panel. The U.S. is the second largest global carbon emitter, despite having a much smaller population than the other top emitters, China and India.

If we don’t solve the greenhouse gas problem by mid-century, warned MacDonald, we will soon hit 700 ppm of carbon dioxide in the atmosphere. If that happens, “We’re back to the Miocene era,” he said, referencing an exceptionally hot period around 12.5 million years ago. “Northern Hemisphere land temperatures will be 11 degrees Fahrenheit warmer. Arctic temps will be 17°F warmer, which is probably going to launch a huge permafrost thaw … The ocean will be 80% more acidic. So we are in an urgent situation.”

What’s the path to a more sustainable future? Decarbonizing the grid.

The energy sector is one of the top sources of U.S. emissions—and reducing emissions there will have knock-on effects in buildings and transportation. Lee noted that wind and solar power have dropped dramatically in price, becoming the cheapest forms of energy generation available. This has led to an increase in adoption: renewables are now second only to natural gas in terms of electrical power generated in the United States. Yet natural gas is still growing fast, and still far exceeds the use of renewables.

Therefore, Lew said in her talk, we need “massive buildouts of [wind, solar, and battery] resources … doubling or even tripling the amount of installed capacity. We’re going to be electrifying buildings, transportation, industry [and] massively building out transmission and distribution networks … And we’re going to be using fossil fuel generators for reliability needs.” Doing this could get us to 80-90% fossil-free energy production.

Bridging the gap

But what about that last 10–20%?

“We need some kind of cost-effective, clean, firm resource” to fill in the gaps and act as a bridge fuel—a resource that’s available 24/7 no matter the weather or season—said Lew. This resource might end up being hydrogen, advanced nuclear energy, or even green bioenergy with carbon capture and sequestration to offset emissions from natural gas. “We need all options on the table.”

Weather? Or not?

Trying to transition to renewables without incorporating reliability and resilience will lead to blackouts and power outages, Tuohy noted. These would have major economic consequences and reduce the political viability of renewables, as well as leading to unjust allocation of energy.

A resilient grid, he said, requires enough energy production to meet future demand; adequate transmission and delivery infrastructure to meet future needs and to balance supply with demand moment-to-moment every day; reliability despite constant shifts in energy production; and the ability to prevent a problem in one place from causing cascading outages across the system. 

Making a new, wind- and solar-dependent grid truly work means balancing—and forecasting—energy availability and demand across the nation, accounting for the current and predicted weather at each solar and wind energy site, as well as how climate change will affect resource availability. This means a massive meteorological infrastructure must be created.

Read our upcoming post from Justin Sharp to learn more about how weather and renewable energy must work together.

“[This is] an operational need, not a research project … There’s an imperative to have dedicated, accurate, and expertly curated weather information to support the energy transition.”

—Justin Sharp

Uncertainty

Demands on the grid are now subject to extreme variability, not just from weather and climate, Tuohy said. For example, demand projections from 2022 versus 2023 were radically different because of new energy-intensive data centers coming online.

“We’ve gone from a kind of deterministic system — [in which we] had good sense of, our peak demand’s going to happen in July—to a far more stochastic and variable type, both on the demand and the supply side,” said Tuohy. We have a lot of data and computational tools, but we must be able to bring those datasets together effectively so we can analyze and predict change. “We need to … develop tools that account for [uncertainty].”

Changing behavior

The infrastructure required for the necessary expansion of renewable energy generation will be expensive. Keeping the cost manageable means not wasting money to build extra infrastructure that’s only useful during times of peak demand. That means we need to avoid high peaks in energy use.

We know that people can be a lot more conscientious about energy consumption if they think it will save them money. Yet many consumers are currently sheltered from the financial consequences of overloading the grid. “There’s tremendous flexibility in load if you … expose consumers to better price signals,” Lew said.

Consumers could be financially incentivized, for example, to choose off-peak times to turn on a heater or charge an electric vehicle. Such programs should be carefully designed to minimize negative impacts on vulnerable consumers, but the fact remains that to keep those consumers safe, the climate crisis must be confronted.

Supergrid to the rescue?

The main problem with a renewable energy grid, the speakers acknowledged, is transmission—both connecting new generators and moving energy based on supply and demand. “You’ve got to be able to move wind and solar energy around at continental scales,” said MacDonald. A study by ESIG suggested that simply adding a 2-gigawatt transmission line connecting the Texas power grid with the Eastern U.S. power grid would effectively act like 4 GW of extra electricity generating capacity across the two regions, because their grids experience risk and stress at different, complementary times.

A 2016 paper MacDonald and colleagues published in Nature Climate Change suggests that U.S. electricity-sector carbon emissions could be decreased by 80% — with current technology and without increased electricity costs — if the United States can implement a “supergrid.” That means connecting all three major electrical grids currently serving the continental United States. When it’s sunny in San Jose and snowing in Cincinnati, you could transmit solar-produced energy to keep Ohio homes warm, rather than generating extra power locally. 

It will take a lot of effort, but “if we [start implementing a supergrid] now, in a 40-year transition, we can preserve the environment we have,” MacDonald said. “If we wait until the 2040s, we are basically going to devastate the planet’s life for thousands of years.”

Successful Science Policy Means Advocating for People

By Joseph Patton, Faculty Researcher for the Earth System Science Interdisciplinary Center at the University of Maryland, College Park

Note: This is a guest blog post; it represents the views of the author alone and not the American Meteorological Society or the AMS Policy Program. Geosciences Congressional Visits Day is non-partisan, and promotes policy engagement without advocating for particular viewpoints. AMS has not taken a position on the legislation discussed by the author in this post.

In the pursuit of scientific advancements which benefit our communities, sometimes society and lawmakers lose perspective of the research workforce. A significant portion of scientific labor is done by postgraduate students and early-career professionals who often struggle to make ends meet while living in the large, expensive urban areas where their institutions are located. This puts undue financial stress on people who are already working long hours through nights and weekends to find and implement solutions to global problems. This financial insecurity threatens not only the livelihoods of these individuals, but also the quality of their work. No matter their academic wherewithal, someone who is constantly worried about making rent or affording groceries that month may accomplish less, or experience failing mental and physical health. I’ve noticed in my own work extreme disparities in pay for graduate researchers at higher education institutions that are just a few miles apart from each other in Maryland. I believe that it is paramount to our goals of advancing scientific research to ensure that the researchers carrying out this work are able to meet the basic needs of life.

That is why, this September, I was excited to take part in the Geosciences Congressional Visits Day (GEO-CVD) hosted by the AMS and other Earth science societies. GEO-CVD provides a one-day workshop on the federal policy process, followed by a day of visiting Congressional offices, meeting with staff to discuss issues that participants feel are important. My group, which included colleagues from the University of Maryland system, traveled to Capitol Hill to discuss several bills which directly address the financial and residential insecurities of the backbone of our scientific research workforce. 

Our team met with the staff of the two Maryland senators, as well as the representative for the Congressional district including the University of Maryland.

The Bills

One bill for which my group advocated was the RESEARCHER Act, which directs the White House Office of Science and Technology to develop new policies and guidelines for federal research agencies to address the underlying causes of financial insecurity for student and early-career researchers. It would then require federal agencies to implement these policies. Such policies might include standardizing the pay of graduate and early-career researchers working under federal grants at public universities such as UMD, or new guidelines on official employment status and the availability of adequate, affordable healthcare, in addition to more issues surrounding their quality of life.

Another bill we advocated for is the Keep STEM Talent Act. The United States attracts some of the best talent from all throughout the world with our first-rate universities and research institutions. Yet in addition to broad financial insecurities, many foreign nationals struggle with challenges in maintaining residency in the United States. The Keep STEM Talent Act would exempt researchers with a master’s degree or higher in their field of study from immigration limitations when seeking an immigration visa as a step toward permanent residency status. It would also allow those individuals to pursue an immigrant visa even while living in the country on a non-immigrant visa (e.g., a student visa). This would give the top minds in STEM fields a more secure way to approach living and working in the United States, while maintaining their ability to study and work at American universities in the meantime. Such changes would benefit the research capabilities of institutions across America and nurture the careers of scientists like my colleague Daile Zhang, a foreign national from China and a pioneering lightning researcher. After working in the United States for nearly a decade, she just this fall accepted a tenure-track faculty position at the University of North Dakota.

Being Heard

Experiencing what it’s like to walk down the winding halls and seemingly endless basements of the buildings surrounding the U.S. Capitol Building was a career-defining opportunity. We briefly got to meet, in person, our representative in Congress, and feel like our voices were heard. We discussed issues close to us as researchers and as people. We genuinely feel empowered by the opportunity to effect change both in Maryland and at a federal level.

One thing I’ve learned from my career so far (I’ve been a graduate student, a federal employee, and now a faculty researcher), is that nearly every researcher is in their niche STEM field because they are incredibly passionate about the work that they do. Whether that’s an astrobiologist studying how to grow plants on Mars, a chemical engineer finding the next breakthrough in energy storage, or an oncologist working on the cure for a specific type of cancer, we blur the lines between work and personal time and spend long hours in the lab or at our workstations because our work is a part of who we are as people. It’s not for money, fame, or even recognition; it’s to make sense of the complicated natural world in which we all live, explore new possibilities, help people feel safe and secure in a sustainable way of life, and better our communities. When we take care of researchers, we all benefit from the result.

I want to send a sincere and heartfelt thank you to the American Meteorological Society for offering us the opportunity to learn about the science policy process as our team set out to advocate for issues that are close to us as researchers. I also want to send a special thanks to Emma Tipton, a policy fellow with AMS, for helping us individually work on our messaging and guiding us through the maze (literally and figuratively) of Congressional advocacy. We appreciate the time and efforts of the Congressional staffers and legislative aides for Senators Ben Cardin and Chris Van Hollen as well as Representative Glenn Ivey.

Hispanic/Latinx Heritage Month Spotlight: Dr. Maria J. Molina

In recognition of National Hispanic Heritage Month (15 September-15 October), the American Meteorological Society is spotlighting the amazing careers and contributions of a few of our Latinx/Hispanic community members. 

This week, we hear from Dr. Maria J. Molina!

What is your current work? Can you tell us a bit about it?

I am currently an Assistant Professor at the University of Maryland in College Park. One of my favorite parts of my job includes conducting research with graduate and undergraduate students, where we use machine learning to answer questions we have about weather and climate. I also get to teach courses like Physical Meteorology and Neural Networks for the Physical Sciences, both of which are really fun!

What was an important moment in your early career?

My years spent at the National Center for Atmospheric Research as an Advanced Study Program (ASP) postdoc and a project scientist were critically important for my career. During my time there, I gained confidence in myself as a scientist through the realization that it’s totally fine to not know things, and that we can always learn and grow at any age. I was able to see world-class scientists say, “I don’t know how to do that,” and then ask others for help, building professional collaborations and learning along the way. This is such a rewarding part of being a scientist; plus, it makes for a much more inclusive work environment.

What is something you’re proud of professionally?

By far, the professional experience I am most proud of is seeing students grow as researchers and critical thinkers. It is immensely rewarding when students start resolving their own software and methodology hurdles, and start coming up with research questions and ways to answer them on their own.

Are there ways in which your Hispanic/Latinx heritage has influenced or enriched your career?

Most definitely. As a Hispanic/Latinx immigrant that experienced extreme weather events growing up in South Florida, I empathize with vulnerable communities that experience extreme weather, oftentimes having to navigate complex decisions with language and cultural barriers. It has helped me appreciate the work done by social scientists and keep the human component of the Earth systems in mind as I conduct my research.

Hispanic/Latinx Heritage Month Spotlight: Anthony Yanez

In recognition of National Hispanic Heritage Month (September 15-October 15), the American Meteorological Society is spotlighting the amazing careers and contributions of a few of our Latinx/Hispanic community members. 

This week, we hear from Anthony Yanez!

What is your current work? Can you tell us a bit about it?

I recently became the Chief Meteorologist at KPRC 2, the NBC affiliate in Houston, Texas. This has been a long-time goal to reach, and it finally happened July 1st.

What was an important moment in your early career?

My career began in the sports department in my hometown of Albuquerque, New Mexico. After several years, I transitioned to the newsroom as a reporter and anchor. A pivotal moment in my career occurred when my boss saw a potential in me in another department. He said, “You have a better personality for weather. I’m moving you to the weather department.” His insight led me to discover a love for meteorology. Under the mentorship of Mike Hernandez, the chief meteorologist at the time, I received invaluable guidance that significantly shaped my career.

What is something you’re proud of professionally?

A highlight of my career was receiving the 2022 AMS Award for Excellence in Science Reporting by a Broadcast Meteorologist. My work in Los Angeles, covering wildfires, oceans, and climate issues, was both impactful and deeply fulfilling.

Are there ways in which your Hispanic/Latinx heritage has influenced or enriched your career?

As a Hispanic professional, I take pride in serving as a role model for the rapidly growing Hispanic community in the United States. During school visits, I make it a point to tell students that if I can achieve success, they can too. Additionally, my involvement with the Hispanic community in Houston, including serving as a past president of the Houston Association of Hispanic Media Professionals, enables me to support aspiring journalists by awarding college scholarships to deserving students.

How is Weather Research Changing?

A 2024 AMS Summer Community Meeting highlight

The AMS Summer Community Meeting (SCM) drew exceptional attendance and engagement this year as people across sectors helped inform a major upcoming report on the Weather Enterprise. The AMS Weather Enterprise Study will provide a comprehensive picture of the shifting landscape of weather-related fields to inform our joint future. At the 2024 SCM, working groups discussed what they’d found about key issues facing the enterprise, and asked for feedback from the community. 

Here are a few takeaways from the Research Enterprise working group, as reported by Daniel Rothenberg of Brightband.

How has the weather research landscape shifted in the last decade or so?

Two of the most important shifts have been a movement of exploratory and applied research from the public to the private sector, and the rise in importance of “data science” and other hybrid roles blending a mixture of domain expertise and broader engineering and technical skills. 

Possibly the biggest example of these shifts coming together has been the advent of AI-based weather forecasting tools, although it also shows in trends such as the rise of private companies operating earth observation platforms.

What were the principal themes that came out of your working group’s discussions?

One major theme we discussed was the balance of responsibilities across the traditional weather enterprise. Initiatives such as building and launching satellite constellations or developing new weather models were at one point solely within the remit of the public sector (due to complexity and cost), but are now commonly undertaken by the private sector – sometimes even at start-up companies.

This re-balancing opens as many opportunities as it does challenges, and leads to another major theme: how we can best prepare for the workforce needs of today and tomorrow. Meteorologists will increasingly need to apply technical skills such as software development and data science alongside ones from the social sciences; preparing our current and future workforce for these demands will be a challenge in its own right.

A third major theme is that the weather enterprise is getting bigger. We’re not just a community of meteorologists anymore. Increasingly, critical work related to weather, water, climate, and their impacts on society is being undertaken beyond the traditional boundaries of our enterprise. There is a significant opportunity to improve society’s resilience if we as a community are able to build relationships with the new institutions working on these issues in a collaborative, interdisciplinary manner.

What are the main challenges you have identified?

Better accounting for how we ought to invest limited – and declining – federal resources will be a significant and contentious challenge, only complicated by the shifts in priorities and capabilities across the enterprise.

Those shifts motivate a second key challenge, which is clarifying who in the enterprise is accountable for, or has ownership over, certain areas. For example, NOAA makes available nearly all of the observations used in its operational forecast models, with some exceptions for proprietary data from commercial entities. But as more private companies try to sell data to NOAA, how will this balance hold? What if those private companies move towards selling actual weather modeling capabilities or services – perhaps a proprietary AI-based weather model – to the government? In the case of expanding commercial data purchases, who is responsible for maintaining and improving our data assimilation capabilities? 

Coordinating many actors across the enterprise, in a manner that most effectively serves our mission to society, will be a key challenge we must navigate in the coming years.

What preliminary recommendations or future directions have you discussed?

Our tentative recommendations revolve around building robustness. We encourage academic organizations who train our future meteorologists to consider how to prepare these students to work in a multidisciplinary capacity, and to embrace data science skills. Not everyone needs to be an interdisciplinary scientist, but it’s vital that our students learn how to apply their deep domain knowledge as part of a team of such individuals.

We also acknowledge that the rise of AI/ML techniques is changing the demands of our computing and data infrastructure. Not only must our workforce learn to adapt to these technologies, but we must consider how the enterprise will support enabling them: for example, by ensuring that in addition to large, traditional high-performance computing resources, we provide access to GPUs and similar tools. As part of this re-evaluation, we must evolve the ways in which we as a community define our priorities for federal research funding

What did you hear from the community at the SCM?

We thank the community for the warm reception to our assessments at the Summer Community Meeting. Many of the themes we touched on – the re-balancing of capabilities across the enterprise, the emergence of AI/ML and its implications, as well as core workforce development concerns – were echoed across many other working groups, underscoring their importance.

Within our group, we also discussed the growing importance of convergence science, which was echoed several times throughout the meeting. Convergence science, which involves coordinating diverse, interdisciplinary research teams with real stakeholders to solve societally relevant problems, is likely to be an important mechanism of translational research in the future, but we (and others at the meeting) identified a need for federal agencies to devote more resources earmarked for this sort of work in order to complement traditional, siloed funding programs.
