Jet contrails will likely affect climate by 2050

Climate impact of clouds made from airplane contrails may triple by 2050 From the EUROPEAN GEOSCIENCES UNION In the right conditions, airplane contrails can linger in the sky as contrail cirrus – ice clouds that can trap heat inside the Earth’s atmosphere. Their climate impact has been largely neglected in global schemes to offset aviation…

Increasing aerosols may have induced cooling in China

David L. Hagen writes about a new study: Increasing aerosols, decreasing insolation, decreasing temperature, and decreasing precipitable water over 18 years in China.  “Evaluation of Atmospheric Precipitable Water Characteristics and Trends in Mainland China from 1995 to 2012″ Wang 2017 . . .”Moreover, the increasing aerosol loading because of frequent human activities has resulted in…

NASA finds something else climate models are missing…. forcing from 'Secondary Organic Aerosols'

A new paper published by NASA by Tsigaridis and Kanakidou suggests that climate models have missed the forcing effects of organic aerosols, such as VOC’s from trees, oceans, and other sources that combine chemically in the atmosphere to create new compounds. Known as Secondary organic aerosols (SOA), they say “SOA forcing could exceed that of sulfate…

Study: A barrage of viruses and bacteria is falling from the sky

New research may explain why genetically identical viruses are often found in very different environments around the globe. An astonishing number of viruses are circulating around the Earth’s atmosphere – and falling from it – according to new research from scientists in Canada, Spain and the U.S. The study marks the first time scientists have…
