Ecosystem effects of biodiversity loss could rival impacts of climate change, pollutionScienceDaily.com | 03 May 2012
Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study. There has been growing concern that the very high rates of modern extinctions -- due to habitat loss, overharvesting and other human-caused environmental changes -- could reduce nature's ability to provide goods and services like food, clean water and a stable climate.
Stream temperatures don't parallel warming climate trendScienceDaily.com | 03 May 2012
A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate.
Arctic sea-ice loss didn't happen by chanceScienceDaily.com | 03 May 2012
The ongoing rapid retreat of Arctic sea ice is often interpreted as the canary in the mine for anthropogenic climate change. In a new study, scientists have now systematically examined the validity of this claim. They find that neither natural fluctuations nor self-acceleration can explain the observed Arctic sea-ice retreat. Instead, the recent evolution of Arctic sea ice shows a strong, physically plausible correlation with the increasing greenhouse gas concentration.
Greenland glaciers speed up, swelling rising seas: reportsReuters | 03 May 2012
WASHINGTON (Reuters) - Some of Greenland's glaciers are moving about 30 percent faster than they did 10 years ago, contributing to rising global sea levels, but that still may not be enough to reach the most extreme projections for 2100, scientists reported on Thursday.
EU green goals depend on CO2 market-AccionaReuters | 03 May 2012
BRUSSELS (Reuters) - The European Union could fail to hit its green goals unless it manages to drive carbon prices on its Emissions Trading Scheme (ETS) to around three times current levels, Spain's Acciona Energy said.

Africa: Africa Sitting On Sea of Groundwater ReservesAllAfrica.com | 03 May 2012
[Daily Trust] A recent research by scientists from the British Geological Survey and University College London have for the first time mapped the groundwater across the continent and concluded that the mapped water could provide a buffer against the effects of climate change for years to come.
Protestors target energy conferenceThe Independent | 03 May 2012
Climate protesters and anti-cuts demonstrators have targeted a summit of major power firms over high energy bills and greenhouse gas emissions.
Sea-level rises 'may not be as high as worst-case scenarios have predicted'Guardian Unlimited | 03 May 2012
Sea-level rises are unlikely to be as high as worst-case scenarios have forecasted, suggests new research which shows that Greenland's glaciers are slipping into the sea more slowly than was previously thought. But the scientists warned that ice loss still sped up by 30% and is driving rises in sea levels that endanger low-lying coasts around the world.
Environmental groups sue to stop coal leases in WyomingReuters | 03 May 2012
SALMON, Idaho (Reuters) - Citing global warming, environmental groups are asking a federal judge to call a halt in Wyoming to one of the largest coal-mining plans ever approved by the U.S. government.
