Clouds Cool Earth Less Than Once Thought

2013-05-19 15:01:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate News Network: Extra cloud cover caused by emissions of industrial pollutants is known to reduce the effects of global warming, but its impact in reducing temperatures has been over-estimated in the climate models, new research has found. This is particularly significant for China and India, because it has been believed that these two giant countries would be partly shielded from the effects of climate change by their appalling industrial pollution. The Max Planck Institute for Chemistry in Germany believes...

The cloud's the limit for new Arista, Brocade and HP switches

2013-05-06 19:47:24| InfoWorld: Top News

Cloud scaling will be all the switching rage at this weeks Interop. Three major vendors last week took their platforms deeper into and then beyond the data center, outdueling each other on server access density and software programmability, two key attributes needed for the virtualized goldmine called the cloud. And in so doing, they have raised the bar and perhaps set the stage for one of the more anticipated announcements in SDN switching from Cisco spin-in Insieme.

Pollutants Effect On Clouds Could Actually Lead To Climate Cooling

2013-05-06 13:18:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: While manmade pollution and other natural emissions are often blamed for their role in global warming, new research from the University of Manchester suggests that they could actually play a role in cooling the worlds climate. According to the study, which has been published in the journal Nature Geoscience, those emissions could make clouds brighter. Clouds, the researchers explain, are comprised of water droplets that condense onto minute particles suspended in the air. Those particles swell...

Brighter clouds, cooler climate?

ScienceDaily: University of Manchester scientists, writing in the journal Nature Geoscience, have shown that natural emissions and humanmade pollutants can both have an unexpected cooling effect on Earth's climate by making clouds brighter. Clouds are made of water droplets, condensed onto tiny particles suspended in the air. When the air is humid enough, the particles swell into cloud droplets. It has been known for some decades that the number of these particles and their size control how bright the clouds...
