Tropopause cooling a part of natural decadal cycle

The cooling trend observed in the late 20th century at the transition between the troposphere and stratosphere at an altitude of about 15 kilometers is usually believed to be caused by human influences. Now, climate scientists from Kiel And Bergen (Norway) have…

Study links ozone hole to climate change all the way to the equator

In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University’s School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation

Impact of polar ozone depletion on subtropical precipitation

Impact of polar ozone depletion on subtropical precipitation

The ozone hole over Antarctica has been rearranging rainfall patterns throughout the Southern Hemisphere for decades, a new modeling analysis shows. The idea that losing ozone in the cold stratosphere over the South Pole could affect weather in the lower atmosphere…
