Aerosols strengthen storm clouds, according to new study

From the UNIVERSITY OF TEXAS AT AUSTIN An abundance of aerosol particles in the atmosphere can increase the lifespans of large storm clouds by delaying rainfall, making the clouds grow larger and live longer, and producing more extreme storms when the rain finally does come, according to new research from The University of Texas at…

CERN’s CLOUD experiment results suggests industrial revolution reduced cloud cover, cosmic rays have an impact too

From CERN Our planet’s pre-industrial climate may have been cloudier than presently thought, shows CERN’s CLOUD experiment in two papers published in Nature. CERN experiment points to a cloudier pre-industrial climate In two papers1,2 published today in the journal Nature, new results from the CLOUD3experiment at CERN4 imply the baseline pristine pre-industrial climate may have…

Particulates, Aerosols, And Climate: The More Important Story

Guest opinion: Dr. Tim Ball [1] The article “US Senate Considering Albedo Modification Geoengineering Proposal” appeared as I finished this article. It commented on the plan to introduce particles into the atmosphere to increase the reflective capability of the Earth’s atmosphere known as the albedo. Most responses correctly identified it as unwise. Isn’t it already…

#AGU15 Accidental Geoengineering? Airline traffic may help create an icy haze that’s brightening U.S. skies

SAN FRANCISCO, CALIFORNIA —The data just didn’t seem to make sense. That’s often the story right before scientists make a leap in understanding. In this case, scientists had some evidence that skies in the continental United States have been brightening, after several decades of so-called “dimming.” Brightening and dimming are overly simplified words that signify…

Claim: A warmer world will be a hazier one

From the UNIVERSITY OF CALIFORNIA – RIVERSIDE and the Department of Modeled Inconsistent Results comes this unlikely claim: that there will be more of an aerosol load with global warming. Right – negative feedback anyone? A warmer world will be a hazier one Using a suite of computer models, UC Riverside-led study finds most aerosol species…
