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…

Scientists Link Earlier Melting Of Snow To Dark Aerosols

From NASA Goddard: Tiny particles suspended in the air, known as aerosols, can darken snow and ice causing it to absorb more of the sun’s energy. But until recently, scientists rarely considered the effect of all three major types of light-absorbing aerosols together in climate models. In a new study, NASA scientists used a climate…

No surprise here: Jet contrails affect surface temperatures

From Penn State High in the sky where the cirrus ice crystal clouds form, jet contrails draw their crisscross patterns. Now researchers have found that these elevated ice cloud trails can influence temperatures on the ground and affect local climate, according to a team of Penn State geographers. Video follows. “Research done regarding September 2001,…

The Role of Sulfur Dioxide Aerosols in Climate Change

Guest essay by Buel Henry In 2007, the Nobel Prize for Peace was awarded to Albert Gore and the IPCC for their work in promoting the theory that global warming was caused by green-house gasses, and that, based upon computer simulations, increasing amounts of these gasses in the atmosphere would cause runaway warming, with disastrous…
