Earth’s climate may not warm as quickly as expected, suggest new cloud studies
Science Mag By Tim Wogan | May 25, 2016 Federico Bianchi (pictured) and colleagues took the CLOUD instrumentation into the Alps to show sulfur dioxide wasn’t needed to make aerosols. By Tim Wogan May. 25, 2016 , 2:45 PM Clouds need to condense around small particles called aerosols to form, and human aerosol pollution—primarily in the form of sulfuric acid—has made for cloudier skies. That’s why scientists have generally assumed Earth’s ancient skies were much sunnier than they are now. But today, three new studies show how naturally emitted gases from trees can also form the seed particles for clouds. …
