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…

Even the Tiniest Aerosol Particles Can Kick Up a Storm

From the AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE A new study suggests that tiny aerosol particles from pollution plumes have a greater influence on stormy weather over pristine regions of the world, such as oceans and large forests, than previously believed. Because water cycling in these areas contributes substantially to global weather patterns, the human-made…

Another climate feedback found: ‘cooling effect of natural atmospheric particles is greater during warmer years’

  From the University of Leeds and the “settled science” department, comes this new idea that combines measurements with a model. Understanding the climate impact of natural atmospheric particles An international team of scientists, led by the University of Leeds, has quantified the relationship between natural sources of particles in the atmosphere and climate change.…
