Scientist debunks `clouds behind climate change`
A Texas A and M professor has refuted claims that clouds are the root cause of climate change.
Washington: A Texas A and M professor has refuted claims that clouds are the root cause of climate change.
Andrew Dessler, one of the nation’s experts on climate variations, has said that hundreds of studies conducted in the field support the view that clouds are primarily acting as a so-called “feedback” that amplifies warming from human activities.
Dessler undertook the study of cyclical events El Nino and La Nina over the past 10 years and calculated the Earth’s “energy budget” over this time.
El Nino And La Nina are cyclical events, roughly every five years, when waters in the central Pacific Ocean tend to get warmer or colder and these changes are said to have a huge impact on much of the world’s weather systems for months or even years.
He found that clouds play a trivial role in initiating these climate variations, which is a direct opposition to some previous claims.
“The bottom line is that clouds have not replaced humans as the cause of the recent warming the Earth is experiencing,” he said.
“Over a century, however, clouds can indeed play an important role amplifying climate change.
“I hope my analysis puts an end to this claim that clouds are causing climate change,” he added.
The study will be published in the American Geophysical Union’s peer-reviewed journal Geophysical Research Letters.
