Clouds: The Wild Card of Climate Change

SF Releases Online, Multi-Media Package Featuring University of Miami Researcher Amy Clement

Clouds

MIAMI — October 29, 2010 — As discussions about climate change rage on, one critical factor about this phenomenon has, with few exceptions, failed to capture the media attention it deserves: the important but enigmatic role of clouds in climate change. The role of clouds is important because at any given time about 70 percent of the Earth is covered by clouds. And the role of clouds is enigmatic because clouds can exert opposing forces: Some types of clouds help cool the Earth and some types of clouds help warm the Earth. Which effect will win out as our climate continues to change? So far, no one is certain.

In order to help clear the air on clouds, the National Science Foundation (NSF) is releasing an online, multimedia package on the role of clouds on climate change, entitled, “Clouds: The Wild Card of Climate Change.” It addresses such pressing questions as: Will clouds speed or slow climate change? Why is cloud behavior so difficult to predict? And how are scientists learning about the behavior of these ephemeral, ever-changing, high-altitude phenomena?

The package will include an interview with Amy Clement, professor of meteorology and physical oceanography at the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science. Clement the recipient of the 2007 American Geophysical Union Macelwane Award and the 2007 American Meteorological Society Clarence Leroy Meisinger Award for her work on climate change. Her research on clouds, conducted in collaboration with researchers Robert Burgman (UM) and Joel Norris (Scripps) was published in Science in July 2009. Using observational data collected over the last 50 years and climate models, the team established that low-level stratiform clouds appear to dissipate as the ocean warms, indicating that changes in these clouds could accelerate the warming due to man-made greenhouse gases.

“There is somewhat of a vicious cycle between clouds and ocean temperature potentially exacerbating global warming,” said Clement. “But our findings provide a new way of looking at clouds changes. This can help to improve the simulation of clouds in climate models, which will lead to more accurate projections of future climate changes. ”

“Clouds: The Wild Card of Climate Change” features:

  • a live webcast with cloud and climate expert: David Randall, director of the Center for Multiscale Modeling of Atmospheric Processes and a professor of atmospheric science at Colorado State University;
  • informative, easy-to-understand texts;
  • eye-catching photos and video;
  • dynamic animations;
  • enlightening interviews with cloud researchers, including Clement; and
  • downloadable documents.
