Study: Clouds Do Not Cause Climate Change
2011-09-07 05:23:42

  Clouds only amplify climate change, says a Texas A&M University professor in a study that rebuts recent claims that clouds are actually the root cause of climate change. Andrew Dessler, a Texas A&M atmospheric sciences professor considered one of the nation's experts on climate variations, says decades of data support the mainstream and long-held view that clouds are primarily acting as a so-called "feedback" that amplifies warming from human activity. His work is...

Changes in clouds will amplify the warming of the planet due to human activities, according to a breakthrough study by a Texas A&M University researcher. Andrew Dessler, a professor in the Department of Atmospheric Sciences, says that warming due to increases in greenhouse gases will cause clouds to trap more heat, which will lead to additional warming. This process is known as the "cloud feedback" and is predicted to be responsible for a significant portion of the warming over the next...

Researchers studying climate now have a new tool at their disposal: daily global measurements of carbon dioxide and water vapor in a key part of Earth's atmosphere. The data are courtesy of the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft and confirm the mainstream scientific view that large changes in the climate are likely over the next century. Moustafa Chahine, the instrument's science team leader at NASA's Jet Propulsion Laboratory in Pasadena, unveiled the...

Researchers studying carbon dioxide, a leading greenhouse gas and a key driver of global climate change, now have a new tool at their disposal: daily global measurements of carbon dioxide in a key part of our atmosphere. The data are courtesy of the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft. Moustafa Chahine, the instrument's science team leader at NASA's Jet Propulsion Laboratory, Pasadena, Calif., unveiled the new product at a briefing on recent breakthroughs...

A U.S.-Australian study has determined high humidity levels, through a process called water vapor feedback, can aggravate global warming. Texas A&M University Professor Andrew Dessler says warming due to increases in greenhouse gases will lead to higher humidity in the atmosphere. And because water vapor itself is a greenhouse gas, this will cause additional warming. It's a vicious cycle, said Dessler. Warmer temperatures mean higher humidity, which in turn leads to even more warming. For...

Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change. Andrew Dessler and colleagues from Texas A&M University in College Station confirmed that the heat-amplifying effect of water vapor is potent enough to...
