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...

From Cornell Chronicle By David Nutt | October 1, 2018 Atkinson Center for a Sustainable Future This graphic shows the decline of black carbon emissions from fire activity from 1700 to the present, contrasted with the...

Polar jet circulation changes bring Sahara dust to Arctic, increasing temperatures, melting ice Summary points A new atmospheric mechanism by which dust travels from the Sahara Desert across the eastern side of the North...

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...

Observations during lunar eclipses show how Earth’s atmosphere has cleared, letting in more sunlight Strange but true: You can learn a lot about Earth’s climate by watching a lunar eclipse...

From the NORWEGIAN UNIVERSITY OF SCIENCE AND TECHNOLOGY and the “wood stove police will soon come knocking” department comes this claim: Your wood stove affects the climate more than you might think Black carbon...

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...

From the “models aren’t the same as reality unless you have a bigger computer” department. Global climate is a tremendously complex phenomenon, and researchers are making painstaking progress, year by year,...

Atomspheric physicists have found that the way wildfire smoke from Africa interacts with clouds over the Atlantic Ocean results in a net cooling effect, which is contrary to previous understanding and has implications for...

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...

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...

Guest Opinion: Dr. Tim Ball I was halfway through the final draft of this article when the study appeared in Natural Geoscience titled “Substantial large-scale feedbacks between natural aerosols and climate.” A useful...

  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...

How can you see the atmosphere? By tracking what is carried on the wind. Tiny aerosol particles such as smoke, dust, and sea salt are transported across the globe, making visible weather patterns and other normally invisible...
