The vast majority of members of the American Meteorological Society agree that recent climate change stems at least in part from human causes, and the agreement has been growing significantly in the last five years.
According to a new survey of AMS members, 67% say climate change over the last 50 years is mostly to entirely caused by human activity, and more than 4 in 5 respondents attributed at least some of the climate change to human activity.
Only 5% said that climate change was “largely or entirely” due to natural events (while 6% said they “didn’t know.”)
The findings are from the initial results of a 2016 national survey of more than 4,000 AMS members just released today by George Mason University. The joint GMU/AMS study was conducted in January with support from the National Science Foundation.
Four in five respondents say their opinion on the issue has not changed over the last five years, but of the 17% who did shift, 87% said they feel “more convinced” now that human-caused climate change is happening. Two-thirds of them based this change on new scientific information in the peer-reviewed scientific literature, although in general respondents report basing these changes on multiple sources of information, such as peers and personal observation. Indeed, 74% think that their local climate has changed in the past 50 years.
AMS membership is largely constituted of professionals in the weather, water, and climate fields. One-third of the respondents hold a Ph.D. in meteorology or the atmospheric sciences, and overall just more than half have doctorates in some field.
Yet, while highly educated, the AMS membership represents a different selection of the profession than the climate-expert community commonly cited in statistics about the scientific consensus on climate change. Only 37% of AMS respondents self-identified themselves as climate change experts.
As a result, despite the growing agreement among the membership, there are differences in the results of the new survey compared to the position of climate scientists reflected in the reports of the IPCC.
On one key basic point the difference between the climate expert community and the AMS community as a whole is nearly negligible: AMS members are nearly unanimous (96%) in thinking that climate change is occurring and almost 9 in 10 of them are either “extremely” or “very” sure of this change. Only 1% say climate change is not happening.
However, the AMS Statement on Climate Change, which basically reflects the IPCC findings, not only says “warming of the climate system now is unequivocal” but also says, “It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases.” The new survey shows the AMS community as a whole is still moving toward this state of the science position. Furthermore, the new GMU/AMS survey does not probe members’ views on specific mechanisms of human-caused climate change.
Full results of the survey, including what members think of the future prospects for climate change, are posted here.

2015: The Hottest Hiatus
It was predicted early and often—and now, finally, it’s official. Throughout 2015, climate-watchers at NOAA and NASA were giving indications that the world’s surface temperature was going to top every annual mean measured since records began in 1880. Today, the two agencies with independent analyses jointly confirmed that global surface temperatures in 2015 blew away the record set in 2014.
The mean global temperature in the analysis by NASA’s Goddard Institute for Space Studies was 0.13°C above the 2014 record, and NOAA’s National Centers for Environmental Information had it as 0.16°C above. In all, according to NCEI, 2015 was 0.90°C above the 20th-century average.
The temperature record was no surprise, even though 2015 set a new record by the largest margin ever recorded. In the horse race of annual temperatures, 2015 jumped out of the gate ahead of the pack and never looked back at previous record holders like 1997, 2005, and 2014 (see the NOAA graphic below). It was a wire-to-wire victory in which 10 of 12 months were the hottest ever on record for their respective periods. Indeed, going into the homestretch, NCEI pointed out that December 2015 would have to stumble to more than 0.81°C below average to avoid setting a record. Instead, December extended the year’s lead by registering 1.11°C above the 1880-2015 century average—in other words, it was the hottest month in the century-plus of measurement history.
Inevitably, the question arises: does this record conflict with the notion of a “hiatus,” which the IPCC addressed in its Fifth Assessment Report in 2013? Trend aside, 15 of the 16 hottest years on record have occurred in this still-young 21st century, according to NASA; NOAA says four different years in that brief period have now reset the global surface temperature record.
Not surprisingly, a decade or so is a mere blip in climatology terms, and the short-term trend of global warming depends on where you mark the start and end point of your analysis. The warming has been relatively fast since 1970—about 0.16 or 0.17°C per decade, depending on your dataset. If you just look at only 1998-2012, as IPCC did, during sustained warmth near record levels, the upward trend is half what it is over the longer period. Of course, starting with 1998 means starting out very warm—hence a trend with major handicapping.
As a result, there’s been scientific backlash against use of the term “hiatus.” As Stephan Lewandowsky, James Risbey, and Naomi Oreskes point out in a newly released article in BAMS, the word doesn’t fit:
The meaning of the terms “pause” and “hiatus” implies that the normal fluctuations in warming rate have been surpassed such that warming has stopped.
They show that warming looks slower or faster depending on the start date of any given 15-year period, but that none of the slowest-warming periods, including the last 15 years, is any slower than one might expect in a warming climate post-1970 (or indeed less remarkable with longer periods one might choose). They conclude,
The “pause” is not unusual or extraordinary relative to other fluctuations and it does not stand out in any meaningful statistical sense.
Lewandowsky and colleagues go on to show that, objectively, “hiatus” doesn’t pass the eye test. When tested by looking at a curve resembling the global temperature curve, experts and nonexperts alike perceived a long-term, uninterrupted upward trend. The authors conclude that misuse of the word “hiatus” distorts how the data look, and thus impedes not only public perception of global warming but also scientific work.
One benefit of the “hiatus” talk is that scientists have been motivated to ask more questions about the normal short-term fluctuations of climate. One purpose of the Community Earth System Model’s Large Ensemble Project, for example, is to produce large numbers of climate model simulations to help “disentangle” model error from internal climate variability—that is, the fluctuations caused by climate irrespective of anthropogenic forcing.
In an article in the August issue of BAMS, the ensemble project’s investigators show a sample experiment in which the slower warming of the last 15 years has actually been a pace well within normal variability, with or without greenhouse gas forcing (see figure below).
As the world continues to warm, this year’s record is prone to fall. Meanwhile, the ensemble also shows that the odds of a 10- or 20-year fluctuation stopping the warming—let alone a brief cooling—keeps getting tinier and tinier.
Letting Scientists Benefit Us All
Lately you may have noticed that AMS has garnered media attention by standing up for NOAA scientists who are the focus of Congressional scrutiny. This scrutiny was initiated after the scientists re-analyzed global surface temperatures with newly corrected data and found that the warming trend of the second half of the 20th century has been continuing unabated since 1998 instead of experiencing what sometimes has been portrayed as a warming “hiatus.”
AMS doesn’t step casually into political arenas. As a non-profit scientific and professional society, we remain solidly grounded in the world of science. We help expand knowledge and understanding through research and, as our mission states, we work to ensure that scientific advances benefit society. We engage the policy process to help inform decision making and to help ensure that policy choices take full advantage of scientific understanding.
This case is slightly different, however, because the scientific process itself is at risk. When the scientific process is disregarded or, worse yet, possibly derailed, a political issue can become an AMS issue.
The scientific process that AMS and other like-minded institutions have championed over the centuries is about taking careful observations, conducting controlled experiments, separating personal opinions and beliefs from evidence, and, perhaps most critically, exposing scientific conclusions to rigorous and repeated testing over time by independent experts. These repeated cycles of distribution and “trial by fire” happen most notably at meetings, in peer-review, and in publication.
Crucially, the process systematically removes as much as possible of our human tendency to see what we want to see and puts the burden of proof on reproducible steps. It is a disciplined, particular way of finding truths, no matter how elusive, while rendering biases, opinions, and motivations as irrelevant as possible.
This systematic approach to separating fact from opinion occasionally goes astray, of course, but its iterative nature means that science is continually self-correcting and improving; better data and understanding ultimately replace older thinking. Science encourages people to question and challenge thinking, certainty, and accuracy—but it requires they focus exclusively on what they can detect and measure and reason.
Even though all the data, logic, and methodologies are publicly available, the paper rejecting the global warming hiatus inspired Congressional requests for additional email and discussions. Asking for these correspondences—especially from scientists themselves—can easily weigh down the ingenious process by which science has continually advanced. And so AMS made public statements in favor of letting science freely work its wonders. It’s not the first time AMS has done so, and it probably won’t be the last.
We owe much of modern prosperity to an unencumbered scientific process, and it continues to provide some of the most profound and dramatic advancements in the world. This includes medicine, biology, chemistry, computing, agriculture, engineering, physics, astronomy, and, of course, meteorology, hydrology, oceanography, and climatology. Every one of us benefits every single day from what scientists have learned, shared, and provided.
And that’s yet another reason why occasionally AMS must speak out—because of our mission “for the benefit of society.” The point is not just to protect science but also to protect the benefits that knowledge can provide to all of us, no matter what we think of the results. In this, our scientific society actually has much in common with the politicians and policy makers in Washington, D.C.
AMS stands behind the scientific process and will defend that process when necessary, but our goal is to work with policy makers to promote having the best knowledge and understanding used in making policy choices.
From Florida, A Reminder About Freedom of Expression
The Florida Center for Investigative Reporting published allegations this week that the terms “climate change” and “global warming” were banned from state government communications in Florida, including state-agency sponsored research studies and educational programs. The Washington Post followed with claims, for example, that a researcher was required by state officials to strike such words before submitting for publication a manuscript about a epidemiological study.
No evidence of a written policy or rule has been reported, and state officials have denied any policy of the sort. Meanwhile, the media are hunting through Florida websites trying to find state documents produced during the administration of Gov. Rick Scott with contents that would contradict the charges of an unwritten policy, imperfectly enforced.
The controversy is one in a string of recent events reminding us how much scientists rely on their freedom of expression. Most often the problem has been the freedom of government scientists to speak about their work with the public. Lately this has caused a media blizzard in Canada.
Science ethicists may argue one way or another about where the limits of public expression are for government scientists when they contradict policy goals. And certainly—as well seen most obviously in the Cold War—such goals can include national security concerns. But the AMS stance on the filtering or tampering of science for nonscientific purposes is quite clear in the Statement on Freedom of Expression:
The ability of scientists to present their findings to the scientific community, policy makers, the media, and the public without censorship, intimidation, or political interference is imperative.
Freedom of expression is essential to scientific progress. Open debate is a necessary part of science and takes place largely through the publication of credible studies vetted in peer review. Publication is thus founded on the need for freedom of expression, and it is in turn a manifestation of freedom of expression.
One might think the job of journals is to screen out unwanted science, but it’s quite the opposite. Papers are published not because they are validated as “right” so much as they are considered “worthy” of further scientific consideration. In addition, the publication process itself—which AMS knows well in its 11 scientific journals—is not just for authors to report and interpret their work. It relies on free discussion. The peer review process usually allows reviewers maximum protection of anonymity to preserve the ability to speak freely about the manuscripts being scrutinized. The papers that pass review are then the starting point for documenting objections, alternative interpretations, and confirmation, among other expressions that only matter if made accessible to other scientists through peer reviewed journals.
The AMS Statement recognizes that such freedom implies responsibility:
It is incumbent upon scientists to communicate their findings in ways that portray their results and the results of others, objectively, professionally, and without sensationalizing or politicizing the associated impacts.
Scientists are not the only ones to treasure such freedoms, of course. Society benefits from the progress of science every day. This only happens when scientists freely, promptly, and prolifically report what they find—and that means exactly what they find, not what they are told to find. The alternative is to compromise the pursuit of truth and the very foundations of our health and prosperity.
We all become victims when science is not shared and cannot flourish. The fact that climate change has deep social, economic, and political implications today means it is even more important to recognize that with increasing value of climate change science comes the increasing temptation for policy makers to co-opt and alter that science. As the AMS Statement warns, the principles of free expression “matter most—and at the same time are most vulnerable to violation—precisely when science has its greatest bearing on society.”
AMS Presidential Town Hall Meeting to Stress Adaptation, Resilience to Climate Change
In weather forecasting, the past is often a harbinger of the future. In a rapidly urbanizing world facing climate change, however, the future looks less and less like the past. With a theme of Building, Sustaining, and Improving our Weather and Climate Hazard Resilience, we’re facing this problem head on at the AMS Annual Meeting, nowhere more so than in tonight’s Presidential Town Hall Meeting (7:00–8:30 p.m., Room C111 of the Georgia World Congress Center).
The speakers include FEMA Administrator Craig Fugate and an IPCC coordinating lead author, Donald Wuebbles—two key figures in communicating climate change hazards and adaptation. Helping all to visualize extremes in the weather will be NCAR’s Mel Shapiro—a master at telling a tale through stunning imagery. This time his tale is Superstorm Sandy, which crashed ashore in the Northeast in fall 2012 with deadly fury. Sandy exposed just how vulnerable our nation is to natural disasters. Storm surge flooding didn’t just wreck the beaches, our playgrounds at the shore. Seawater rushed inland, flooding airports and mass transportation routes and partially disconnecting the biggest city in America—and financial heart of the nation—from its neighbors. The price tag was enormous.
You’ll hear a lot at the Town Hall about how weather- and climate-driven disasters in America are costing us more and more. Multibillion-dollar weather disasters, once consisting solely of major hurricanes and extended drought, are becoming common—even from small-scale thunderstorms. With a climate that’s heating up–resulting in an increase in extreme weather, as Wuebbles will discuss–so too will we see an increase is such megadisasters.
Wuebbles’ playbook on Monday will be the fifth assessment report (AR5) of climate change by the Intergovernmental Panel on Climate Change (IPCC). Wuebbles was coordinating lead author of the Working Group 1 section, which was released in full form last week. He says he plans to overview its findings with “an emphasis on our state of understanding of severe weather events under a changing climate.” The presentation will include a preview of the U.S. National Climate Assessment to be released in April.
Wuebbles, who is an atmospheric science professor at the University of Illinois, will also report from a series of NOAA workshops evaluating attribution science (in BAMS here, here, and here), which currently supports making useful projections on some but not all types of severe-weather events. Projections of heat waves and cold spells as well as heavy precipitation events are now possible, and “meaningful trends in floods and droughts” are also discernible by region in the United States. Confidence in an increase in hurricane intensity as the climate warms is also growing. But forecasts of how climate change will affect severe thunderstorms and tornadoes, which in recent years have broken into the billion-dollar disaster range, remain out of reach for now, Wuebbles says, but he adds, “By the next assessment we may be able to make stronger statements.”
Even without the financial burden, today’s weather disasters are becoming debilitating. Look no further than last week’s shutdown of Atlanta due to a well-forecast snowfall. It shouldn’t have happened—particularly since the city went through the same thing just three years ago (January 2011), only with a slightly heavier snowfall. No one thought it could happen again, but it did.
Our ability to successfully communicate is challenged most when disaster strikes. That’s where Fugate comes in. As the top emergency manager in the nation, his job is to organize meaningful and rapid response, which relies on successful communication.
The key is to organize lines of communication beforehand, so when the weather becomes extreme, the avenues of information will remain open. But there are other forms of disaster response. Fugate sees resilience to disaster through increasing adaptation as the way forward in a changing climate. By reducing the risk, he believes we can manage to recover more quickly from extreme weather events. Most importantly, in his view, is to turn victims of disaster into what he prefers them to be called: survivors. He encourages neighbors and communities to get better at coming together when disaster occurs and to help each other overcome the odds and survive.
As AMS Associate Executive Director Bill Hooke explains in Sunday’s Living on the Real World column, there are many levels of disaster response, and all of them “need to be mastered.” When disaster strikes a community, its residents probably will look to the top command-and-control such as FEMA to make things right. But at the other end of disaster response is personal responsibility. Each of us has the task before us to take action to improve our situation. We can wait for disaster to strike, but better would be to plan now how to adapt and make ourselves resilient to weather and climate hazards so they won’t turn into catastrophes.
BAMS Report Editors Named "Leading Thinkers" of 2013
The September issue of BAMS included a special supplement, “Explaining Extreme Events of 2012 from a Climate Perspective,” edited by Thomas Peterson, Martin Hoerling, and Stephanie Herring of NOAA and Peter Stott of the UK Met Office. This was the second edition of this annual investigation of the causes of recent extreme events. The supplement consists of short, concise studies by various author teams and thus serves as a demonstration of the latest methodologies for attributing specific events to longer term trends in climate. For their work on the report, Peterson, Hoerling, Herring, and Stott are lauded in this month’s issue of Foreign Policy magazine as “Leading Global Thinkers of 2013.”
Foreign Policy called the report “a breakthrough in climate science” for connecting extreme events like Hurricane Sandy to human-influenced climate change. The magazine praised the report’s four editors for “point[ing] problem-solvers in the right direction” on better understanding the causes of extreme weather and climate events. Upon learning about the honor, the four noted that the recognition highlights the value that studying extreme events can provide to global security and sustainability.
“It is clearly an acknowledgement that attribution of extreme events is an important scientific topic—that the results of event attribution research can help guide real-world, climate-smart actions,” Peterson told Climate.gov.
The editors also noted that the tribute “honors the collective effort” of all climate scientists studying extreme events, and specifically the 18 different research groups that contributed to the BAMS report. Of course, extreme events will be a featured topic at the AMS Annual Meeting in Atlanta in February, as the theme of the meeting is “Extreme Weather–Climate and the Built Environment: New Perspectives, Opportunities, and Tools.”
Foreign Policy‘s 100 Leading Global Thinkers of 2013 are divided into 10 categories ranging from “the innovators” and “the healers” to “the artists” and “the decision-makers.” The coeditors of the BAMS report were cited in “the naturals” category. Others who made the list of 100 include Vladimir Putin, Pope Francis, the Mars Rover Team, Mark Zuckerberg, Shinzo Abe, and the IPCC. Foreign Policy will be honoring the 100 Global Thinkers at a special event this Wednesday in Washington, D.C.
Watch for the third extreme-events supplement to be released with BAMS next September.
A New Kind of Climate Model Project
Many scientists these days are asking how they can better communicate their research to the public. One group of climate researchers has found a solution–by putting themselves into the spotlight (literally) in the 2014 Climate Models wall calendar.
Scheduled for release this December, the calendar will include pictures of 13 climate scientists as well as information about them, such as their favorite dataset or climate phenomenon. Their ultimate goal, according to their website, is to “increase awareness of climate change and its impacts by engaging the public with scientists and what they’re learning about Earth’s climate.” In the process, the scientists reveal a side of themselves that most of the public doesn’t regularly get to see, and they hope to inspire colleagues to be equally creative in sharing their research with the public. You can get a sneak preview of a few of the models in the video below.
In addition to their work in front of the cameras, the scientists, who represent Columbia University’s International Research Institute for Climate and Society and Lamont-Doherty Earth Observatory, and the NASA Goddard Institute for Space Studies, will also be presenting a poster about their novel communication efforts at December’s AGU Fall Meeting in San Francisco.
You can help support the calendar by donating to its Kickstarter campaign.
Share Ideas on Climate, Influence Policy Options
The Front Page received the following note from John Nielsen-Gammon, Regents Professor of Atmospheric Sciences, Texas A&M University; Texas State Climatologist; and a Fellow of AMS:
A Message To Fellow Physical Scientists
I’m part of a new journalistic endeavor called the Climate Change National Forum and Review. The purpose of this web site will be to provide a public forum wherein scientists can discuss the latest research on climate change and share and debate ideas on aspects of climate change especially relevant to policymaking. When the second phase kicks in, policy experts will join the discussion and compare the benefits and costs of possible responses.
I know what you’re thinking: “This sounds an awful lot like the IPCC.” Well, it’s not. Nor is it intended to replace the IPCC in any way. It has a different purview and a different set of goals.
- The IPCC is an international body. The CCNFR is focused on issues facing the United States.
- The IPCC scientists are selected from nominees from various countries. The CCNFR scientists consist of anyone who contributes regularly and constructively to the discussion.
- The IPCC produces reports every few years, whose summaries are edited and ratified by political representatives. The CCNFR web site is a living document, continuously updated to account for the latest science, and not subject to political interference.
- The IPCC’s purview is anthropogenic climate change. The CCNFR’s purview is climate change in all its causes and manifestations. Would it make sense to only adapt to anthropogenic climate change?
- The IPCC reports are written by experts within their subject fields. The CCNFR will draw upon the expertise and experience of scientists from a wide range of fields, not just insiders.
- The public gets to see the IPCC final report. The public gets to see scientists grappling with, understanding, and debating the issues.
For me, this last point is an important one. The public can benefit tremendously from being able to see how scientists think and reason scientifically. We ask them to trust our collective scientific wisdom without allowing them to see how we evaluate conflicting or flawed evidence and develop judgments. Presently, the only extensive example of this available to the public is the set of emails from Climategate.
Why should you participate? First, you’ll gain a deeper understanding of climate science. Perhaps you’ve just taken the IPCC reports on faith, trusting the experts to do a good job. Whether they did or not, you will be better able to articulate the issues and explain them to others after exchanging ideas, digging into some of the primary literature, and fleshing out any questions that might be nagging you in the back of your mind.
It should be obvious by now that you don’t need to be a climate scientist to participate, as long as you have a suitable technical background. Indeed, we need at least some people who know relatively little about the state of the art of climate science, for their intellectual journey while participating in the CCNFR is similar to the journeys we hope dedicated lay readers will take. Outsiders to climate science can better spot the unspoken assumptions and unjustified conventions.
Your learning will come through the course of online debate and discussion with other scientists. As you probably know from personal experience, discussion with other scientists is often the absolute best way to come to grips with a contentious or controversial scientific issue. Along the way, you will develop skills as a writer for an outside audience.
Finally, you will be doing a public service, simultaneously helping to educate the public about climate change and about science in general.
On the negative side, it requires time, though not a whole lot. We’re only asking for participants to contribute new essays once a month, plus participate in some of the online discussions with other scientists. Compared to starting your own blog, this is a relatively easy way to bring your ideas and judgment into public view.
Scientists who think they know everything about climate change are not welcome to participate. If you’re an expert in a particular branch and want to broaden your knowledge, or even if this is something outside your expertise entirely so that you have a lot you want to learn, then come join us.
The link above that John provides is a beta form of the CCNFR web site. To facilitate your postings explaining, debating, and discussing climate science–and to keep the site tied to issues in the news and policymaking–the CCNFR hopes to provide a steady stream of news and statements culled even-handedly from the media by a professional journalist.
As such, this is not only a time to consider getting in on the ground floor of a new public outreach project but also a time to consider making a donation. The CCNFR hopes to raise more than $60,000 to get a journalist on board soon.
The President's Climate Speech
by Paul Higgins, AMS Policy Program Director
In June, President Obama gave a long-anticipated speech laying out his vision for climate change risk management. The centerpiece of the approach is to use the EPA to regulate greenhouse gas emissions from power plants. What those regulations will look like remains unclear, but the President’s intent to reduce emissions significantly, particularly from coal-fired power plants, is clear.
By all accounts, this wasn’t the approach the president wanted to take for climate change. He has said repeatedly and throughout his presidency that he favors a bipartisan solution that comes from Congress. After nearly five years and with the end of his second term approaching, the president appears to have concluded that the political divisiveness surrounding climate change makes congressional action unlikely.
How well the president’s approach will work is hard to know, of course, but it will be particularly interesting to see how this unilateral effort affects the politics of climate change risk management. There is a chance that the president’s plan will ultimately reduce the political divisiveness surrounding climate change, in part, because the approach itself is politically divisive.
Using the EPA to regulate emissions will not go over well with many in Congress. His opponents will likely find it easy to criticize, and score political points in so doing, on both philosophical grounds (i.e., based on a preference for less intrusive federal intervention) and because unilateral executive action is less democratic than including Congress in the creation of a new law. But the very fact that substantive arguments can be made for different approaches may provide an incentive for his opponents to develop and offer those alternatives. That could create an important opening that’s been largely missing for climate change over the last few decades.
Prior to the 1990, Clean Air Act Republicans and Democrats could more easily agree on an environmental problem yet disagree on the solution. Republicans tended to prefer market-based solutions while Democrats tended to prefer command-and-control regulation. Conservative philosophy convincingly won that debate because the market-based approach used in the 1990 Clean Air Act proved far superior as a tool for protecting the environment and maximizing the economic benefits of doing so.
Perversely, that philosophical victory for conservatives has made it harder for the two parties to agree on climate change risk management. There isn’t an easy way for the parties to distinguish themselves if they agree on the basics of the solution. Instead, the political incentive has been to disagree about whether there is a problem in need of a solution in the first place. Once the champions of climate policy coalesced on a conservative approach for addressing climate change, the choice for everyone else became too stark: go along with that approach or oppose climate policies altogether. If there isn’t middle ground and your opponent is for it, then few options are more politically effective than being against it.
Of course, the politics of climate change are, and will likely continue to be, challenging for other reasons, most notably because of the competing and incompletely reconcilable interests of those affected by policy options. But there is a wide range of potential solutions for helping to manage climate change risks. Critically, there is a policy option for virtually any political philosophy out there. For example, Congress could use a market-based approach to reduce greenhouse gas emissions while simultaneously using every penny that the government raises through such an approach to reduce existing taxes on wages, corporate income, or capital gains. The reduction in taxes that would result would be a major victory for conservatives that many Democrats could plausibly go along with. Yet such options haven’t been developed or seriously considered.
That a broad range of potential risk management strategies hasn’t been developed and explored by policy makers is a major breakdown in our policy process. That policy deliberations (and public debates) about climate science are routinely at odds with the assessments of the relevant subject matter experts is a major failure of our national dialogue on the topic.
These failures have resulted, in part, because the political incentives for developing and exploring policy options have been too weak. By moving to circumvent the current political impasse to climate policy through a unilateral approach (particularly one likely to face sharp political opposition), the president may create a new opportunity for a broader consideration of options. If that happens, whether or not the president’s proposed solution is sufficient, he may help to depolarize the politics of climate change and spur the consideration of new and meaningful approaches to climate change risk management.
AMS Policy Program Director Paul Higgins’s perspectives, including this column, will be appearing regularly in the Bulletin of the American Meteorological Society.
Crowdsourcing the Search for Carbon Dioxide Emissions
According to Arizona State University (ASU) Professor Kevin Gurney, there are approximately 30,000 power plants throughout the world, and collectively they account for close to half of all fossil-fuel CO2 emissions. As a modeler of these emissions, Gurney is trying to learn as much as possible about every one of the plants. Where are they? What kind of fuel does each plant use? How much CO2 does each one release into the atmosphere?
Obtaining this kind of data, however, is a monumental task. There is no worldwide database with all of the power plant information Gurney is looking for, and even after enlisting a number of undergraduate students in his lab to scour Google Earth for the locations of the largest plants, in six months they were able to identify the locations of only 500 across the globe. Realizing that the effort was “like looking for 25,000 needles in a giant haystack,” as Gurney described it, he has now taken another approach by creating an online game that utilizes contributions from the general public to pinpoint the locations of power plants and hopefully quantify the amount of CO2 each releases into the atmosphere.
The project is called Ventus, which is Latin for “wind.” In the game, players are asked for four pieces of information: the location of the power plant (within a few hundred meters), the type of fuel used at the plant, the amount of electricity the plant generates, and the amount of CO2 that is emitted from the plant. Participants in the game can contribute as much information as they have by placing pins on a Google map at the location(s) of the plants. When the game is completed in 2014, the person who contributed the largest amount of useable information will be declared “Supreme Power Plant Emissions GURU!” and will receive a trophy, as well as be a coauthor on a scientific paper about crowd-sourcing in scientific research.
“Our logic is that for every power plant in the world, there are probably at least a dozen people who live near it, work at it, or know someone who works at it” explained ASU’s Darragh O’Keefe, who built the website. “With the proliferation of phones and GPS, it makes it pretty easy to locate things.”
Early response to the game was enthusiastic, with Gurney reporting that people had logged on from almost every country in the world within a day of its mid-May launch.
“I’m always surprised by how fast this type of thing moves around the planet,” he told the Los Angeles Times.
