Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

Earlier observations from satellites and balloons suggest that stratospheric water vapor probably increased between 1980 and 2000, which would have enhanced the decadal rate of surface warming during the 1990s by about 30% compared to estimates ignoring this change, according to the authors.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

Study Provides Evidence That Low-Level Clouds Act as Positive Feedback to Climate Change

Green Car Congress

Time series of annual mean values of cloud and climate quantities averaged over the NE Pacific. (A) 2009), Science. Low-level stratiform clouds—which play an important climatic role because of their net cooling effect on the global climate—appear to dissipate as the ocean warms, thereby enhancing the warming (i.e.,

Study: Single Storm in 2005 Downed Approximately Half a Billion Trees in Amazon

Green Car Congress

A single massive storm in 2005 felled an estimated 441-663 million trees across the Amazon basin, according to a new study accepted for publication in Geophysical Research Letters , a journal of the American Geophysical Union (AGU). In 2005, there was a spike in tree mortality in the Amazon. Jeffrey Chambers.
