Microbes may be small, but they shouldn’t be ignored when considering global climate. According to a new colloquium report from The American Academy of Microbiology, microbes such as bacteria, algae, and fungi play a powerful role in the Earth’s climate. “Incorporating Microbial Processes into Climate Models” notes how the impact of microbes on the atmosphere goes way back in time. The critical mix of carbon dioxide and oxygen we take for granted as sustaining life on the planet is due to the rise of these tiny creatures eons ago.
So what specifically do these minute forms of life have to do with climate today? According to the report, the answer is plenty. “The sum total of their activity is enormous. But of course not all microbes are the same—some of them are producing oxygen, others are consuming it. Some are taking carbon dioxide out of the air, others are adding it.”
The big questions that the report asks and plans to address by incorporating microbial processes into climate change models: what’s the overall effect of microbial activities on the concentration of carbon dioxide in the atmosphere? Is it possible this activity will absorb the carbon dioxide being added to the atmosphere? Or will the rising global temperature might spur microbes to produce even more carbon dioxide?
The authors recognize that the gap between the climatology and microbiology is large, but they say it is not insurmountable. Some of the same technologies used to collect data for climate models—satellite imaging of cloud cover and precipitation, submarine cables that monitor changes in temperature and salinity, sensors to retrieve real-time data from remote locations—can also be applied to measuring biological phenomena. Collaboration between the sciences, they believe, will benefit both fields.

Upping the Ante on Modeling Climate Change Impacts
There is a growing urgency to produce global projections of how a warming climate could affect life on Earth.
“Impact research is lagging behind physical climate sciences,” says Pavel Kabat, director of the International Institute for Applied Systems Analysis (IIASA) in Austria. “Impact models have never been global, and their output is often sketchy. It is a matter of responsibility to society that we do better.”
Time is running out for researchers hoping to contribute impact simulations to the IPCC’s Fifth Assessment Report (scheduled for publication in 2014). So last month, the IIASA and the Potsdam Institute for Climate Impact Research (PIK) started a project to compare climate-impact models collected from more than two dozen research groups in eight countries. The Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP) will integrate climate data from state-of-the-art models, using a range of greenhouse-gas emission scenarios (models used in the project can be found here). Because the various emissions scenarios result in a range of projected global temperature increases, potential impacts also can vary widely across a range of scenarios. It is hoped that the project will clarify systematic biases that can cause models to produce disparate results.
The models will investigate the effects of climate change on global agriculture, water supplies, vegetation, and health. Results are due by July 1, and reports on each of the four impact areas are scheduled to be completed by January of 2013. This means the data could be available for the IPCC’s next report–which “will make a real difference for the assessment process,” notes Chris Field of the Carnegie Institution for Science, cochair of IPCC Working Group II. “I greatly appreciate the initiative required to get this activity underway, and I appreciate the commitment to fast-track components that will yield results in time for inclusion in the IPCC Fifth Assessment Report.”
The ISI-MIP is scheduled to continue into 2013 and could be expanded to analyze climatic impacts on transport and energy infrastructures.
The Zones They Are a-Changin'
The United States Department of Agriculture recently released a map of U.S. planting zones to help gardeners across the country determine what they can and can’t grow. It’s the first new map since 1990, and the changes from the previous map reflect climate variability and change over the last 22 years.
The new map is based on average annual extreme minimum temperatures from 1976 to 2005, whereas the previous map used data from the years 1974-1986. Average temperatures throughout the U.S. were about two-thirds of a degree (F) higher in the more recent time span then they were from 1974 to 1986. As a result, the zones have shifted, and many locations around the country are now in warmer zones than they were on the previous map. Some states, such as Ohio, Texas, and Nebraska, have almost completely migrated to a warmer zone. Of the 34 cities highlighted in the 1990 map, 18 are in warmer zones in the updated version of the map. In general, much of the U.S. is about one-half zone warmer in the new map than in the 1990 edition.
The 2012 version of the planting zones map is the first that is GIS-based. Additionally, a new algorithm used for the 2012 edition enabled more accurate interpolation between weather reporting stations, and the new map also accounts for factors such as elevation changes and proximity to bodies of water, which led to more accurate mapping of the zones. Data used to create the map came from a total of 7,983 stations in the U.S., Canada, and Mexico, including stations of the National Weather Service, the Natural Resources Conservation Service, the Forest Service, the Bureau of Reclamation, the Bureau of Land Management, Environment Canada, and the Global Historical Climate Network.
An in-depth overview of the new map was published in February’s Journal of Applied Meteorology and Climatology. An interactive version of the map and more features can be found here.
Some Good Choices for Your Bookshelf
The Atmospheric Science Librarians International (ASLI) announced their ASLI’s Choice Award winners for 2011 on Wednesday afternoon in the exhibit hall.

Broadcast Meteorology Award Winner Says 'Be Yourself' On-Air
Bob Ryan, meteorologist for WJLA-TV in Washington, D.C., is the 2012 recipient of The AMS Award for Broadcast Meteorology. Ryan is being honored with this annual award in recognition of a career based on personal integrity and dedication to advancing the science of meteorology through broadcasting, education, promotion of safety, and support of colleagues.
Established in 1975, the AMS Award for Broadcast Meteorology recognizes a broadcast meteorologist for sustained long-term contributions to the community through the broadcast media, or for outstanding work during a specific weather event. Ryan, who has been a fixture in Washington TV News for more than three decades, will receive the award at the 92nd AMS Awards Banquet Wednesday evening in New Orleans.
The Front Page caught up with him to learn about how he connects with viewers when on-air and with his colleagues within the AMS. His primary advice for future broadcast meteorologists: “Be yourself,” he says, “and again, you’re talking to one person.” You can view interview below.

Learning to Live with Floods
We all know floods are not friendly. But the NWS and the nonprofit environmental organization Nurture Nature Center (NNC) are taking a new approach to flood education by accepting they are a part of nature that at times cannot be avoided, but can certainly be mitigated. This week’s 21st Symposium on Education will include a poster on the NNC/NWS partnership.
After a series of severe flood events in the Delaware River Valley, the NNC started “Floods Happen. Lessen the Loss,” an education program that emphasizes adaptation over prevention, acceptance over angst, and most importantly, education over ignorance. The program not only provides resources (including interviews with flood experts) and tools, but it also explores the deeper issues of how flooding affects communities and how those communities can live with and adapt to floods. This community-based approach to flood preparation is captured in this animated short film created by the NNC.
One of the key themes of the program is helping communities and individuals learn how to help themselves and then take the initiative to do so. For example, a new NWS flood warning system using Push technology sends out alerts to individuals’ e-mail addresses, internet browsers, and some cell phones . . . but only if the individual takes action and signs up for the alerts. (This link provides a how-to for signing up.) In this video, the NNC’s Rachel Hogan Carr explains how the program addressed another problem–the semantics of the term “100-year floodplain”:
The commonly used, but misleading concept, is the 100-year flood, which leads people to believe falsely that major flooding will occur only every hundred years on average. The truth is that even smaller storms can produce tremendous damage. In many areas along the Delaware River, the flooding in 2004, ’05, and ’06 was much smaller than a 100-year flood, but the damage was nonetheless extensive. And that’s just one problem with the term. The other is that many areas well outside the hundred-year floodplain are liable to flooding, too. In fact, nearly 30% of national flood insurance claims come from outside the 100-year floodplain, often in places where people thought they were safe. That’s why Nurture Nature has started using the terms high, moderate, and low risk to describe various regions of the floodplain.
The NWS/NNC collaboration now has a second initiative: the placement of NOAA’s Science on a Sphere at the NNC’s flood museum, and the creation of the first Science on a Sphere flood-related program, which will explain how climatic and oceanic changes are contributing to the increasing frequency and severity of floods throughout the world.
