Scientists Ask Blunt Question on Everyone’s Mind

Why Earth and atmospheric scientists are swearing up a storm and getting arrested.

Many of us have wondered at some point in almost precisely these terms: “Is Earth F**ked?” But it’s not the sort of frank query you expect an expert in geomorphology to pose to his colleagues as the title of a formal presentation at one of the world’s largest scientific gatherings.

Nestled among offerings such as “Bedrock Hillslopes to Deltas: New Insights Into Landscape Mechanics” and “Chemical Indicators of Pathways in the Water Cycle,” the question leapt off the pages of the schedule for the American Geophysical Union’s fall meeting.  Brad Werner, a geophysicist at the University of California, San Diego, is one of the more than 20,000 Earth and atmospheric scientists who descended on downtown San Francisco this week to share their research on everything from Antarctic ice-sheet behavior to hurricane path modeling to earthquake forecasting. But he’s the only one whose presentation required the use of censorious asterisks. When the chairman of Werner’s panel announced the talk’s title on Wednesday, a titter ran through the audience at the naughtiness of it all.

Why shout out the blunt question on everyone’s mind? Werner explained at the outset of the presentation that it was inspired by friends who are depressed about the future of the planet. “Not so much depressed about all the good science that’s being done all over the world—a lot of it being presented here—about what the future holds,” he clarified, “but by the seeming inability to respond appropriately to it.”

That’s probably an apt description of legions of scientists who have labored for years only to see their findings met with shrugs—or worse. Researchers from the Tyndall Centre for Climate Change Research at the University of East Anglia, for instance, published a paper in Nature Climate Change this week showing that carbon emissions have reached record levels, with a 2.6 percent projected rise in 2012. In another AGU presentation, Pieter Tans of the National Oceanic and Atmospheric Administration posed the question: “Will realistic fossil fuel burning scenarios prevent catastrophic climate change?” He did not seem optimistic. “We might end up burning 900 billion tons of carbon” from oil, gas, and coal, he announced. “We can have a managed path to lower emissions—or do it by misery.” A guy next to me in the audience gave a kind of hopeless snort. The head of NOAA and polar experts held a news conference at the conference entitled, “What’s going on in the Arctic?” This year broke all sorts of records: the lowest recorded sea-ice extent, the lowest recorded snow cover extent and duration, and the most extensive recorded melting event on the surface of the Greenland ice sheet, among other milestones. “I’ve studied Greenland for 20 years now; I’ve devoted my career to it,” Jason Box of Ohio State University intoned somberly, “and 2012 was an astonishing year. This was the warmest summer in a period of record that’s continuous in 170 years.”

Werner’s title nodded at a question running like an anxious murmur just beneath the surface of this and other presentations at the AGU conference: What is the responsibility of scientists, many of them funded by taxpayer dollars through institutions like the National Science Foundation, to tell us just exactly how f**ked we are? Should scientists be neutral arbiters who provide information but leave the fraught decision-making and cost-benefit analysis to economists and political actors? Or should they engage directly in the political process or even become advocates for policies implied by their scientific findings?

Scientists have been loath to answer such questions in unequivocal terms. Overstepping the perceived boundaries of prudence, objectivity, and statistical error bars can derail a promising career. But, in step with many of the planet's critical systems, that may be quickly changing. Lately more and more scientists seem shaken enough by what their measurements and computer models are telling them (and not just about climate change but also about the global nitrogen cycle, extinction rates, fisheries depletion, etc.) to speak out and endorse specific actions. The most prominent example is NASA climatologist James Hansen, who was so freaked out by his own data that he began agitating several years ago for legislation to rein in carbon emissions. His combination of rigorous research and vigorous advocacy is becoming, if not quite mainstream, somewhat less exotic. A commentary in Nature last month implored scientists to risk tenure and get arrested, if necessary, to promote the political solutions their research tells them are required. Climate researchers Kevin Anderson and Alice Bows recently made an impassioned call on their colleagues to do a better job of communicating the urgency of their findings and to no longer cede the making of policy prescriptions entirely to economists and politicians.  

Lonnie Thompson, one of the world’s foremost experts on glaciers and ancient climates, framed the dilemma in a speech he gave to a group of behavioral scientists in 2010:

Climatologists, like other scientists, tend to be a stolid group. We are not given to theatrical rantings about falling skies. Most of us are far more comfortable in our laboratories or gathering data in the field than we are giving interviews to journalists or speaking before Congressional committees. Why then are climatologists speaking out about the dangers of global warming? The answer is that virtually all of us are now convinced that global warming poses a clear and present danger to civilization.

That’s the sound of serious-minded scientists fretting out loud to the rest of us that the earth is indeed f**ked, unless we get our s**t together. More and more are willing to risk professional opprobrium to drive that message home.
