Grazing animals important factor in predicting global warming impact.
August 21, 2008 09:49 AM - Penn State

The impact of global warming in the Arctic may differ from the predictions of computer models of the region, according to a pair of Penn State biologists. The team has shown that grazing animals will play a key role in reducing the anticipated expansion of shrub growth in the region, thus limiting their predicted and beneficial carbon-absorbing effect.

Current climate models 'ignoring brown carbon'
August 18, 2008 10:50 AM - , SciDevNet

Scientists have found that air pollution from East Asia contains an abundance of 'brown carbon' particles and say that atmospheric models need updating to incorporate their effect. Current climate models take into account two types of aerosol carbon — organic carbon and black carbon — that arise from the burning of fossil fuels or biomass.

Antarctic Climate: Short-term Spikes, Long-term Warming Linked To Tropical Pacific
August 15, 2008 09:28 AM - National Center for Atmospheric Research

Dramatic year-to-year temperature swings and a century-long warming trend across West Antarctica are linked to conditions in the tropical Pacific Ocean, according to a new analysis of ice cores conducted by scientists at the National Center for Atmospheric Research (NCAR) and the University of Washington (UW).

Oil and gas projects in western Amazon threaten biodiversity and indigenous peoples
August 13, 2008 10:54 AM - Public Library of Science

According to a new study, over 180 oil and gas "blocks" — areas zoned for exploration and development — now cover the megadiverse western Amazon, which includes Bolivia, Colombia, Ecuador, Peru, and western Brazil. These oil and gas blocks stretch over 688,000 km2 (170 million acres), a vast area, nearly the size of Texas.

Climate change may boost Middle East rainfall

The prospect of climate change sparking food and water shortages in the Middle East is less likely than previously thought, with new research by an Australian climate scientist suggesting that rainfall will be significantly higher in key parts of the region.

Hot subways to floods, all part of NYC climate risk
August 13, 2008 09:32 AM - Reuters

New York City Mayor Michael Bloomberg on Tuesday announced an in-depth study of perils the city faces from climate change, ranging from overly hot subways to shoreline floods. With 506 days left before his second and final term ends, Bloomberg is eager to cement his legacy by shoring up the city's finances and devising long-term plans.
