Greenland Ice is Melting – Faster and Faster!
November 12, 2009 04:13 PM - Roger Greenway, ENN

A new paper, by scientists of Utrecht University, Institute for Marine and Atmospheric Research, in collaboration with colleagues from the Netherlands Royal Meteorological Institute, Delft University of Technology, Bristol University (UK) and the Jet Propulsion Laboratory (USA) was published in Science recently. The work used the Regional Atmospheric Climate Model to calculate surface processes over Greenland, satellite radar measurements to determine iceberg production and ice sheet mass loss from the Gravity Recovery and Climate Mission (GRACE) satellites.

Denmark has formally invited the leaders of United Nations member countries to the U.N. conference in Copenhagen in December that will try to clinch a new global climate deal, the government said on Thursday.

CO2 Emissions are not Changing the Ratio of Airborne CO2 to that taken up by the Oceans and Plants
November 11, 2009 03:14 PM - Roger Greenway, ENN

The University of Bristol in the UK has published a study based not on climate modeling, but on statistical analysis of data including historical data from Antarctic ice cores. The study shows that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now. This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.

Trouble Down Under: Koalas Could Face Extinction

Australia's koalas could be wiped out within 30 years unless urgent action is taken to halt a decline in population, according to researchers. Development, climate change and bushfires have all combined to send the numbers of wild koalas plummeting.

Land Use Change an Overlooked Cause of Global Warming
November 11, 2009 10:27 AM - ScienceDaily

Georgia Tech City and Regional Planning Professor Brian Stone is publishing a paper in the December edition of Environmental Science and Technology that suggests policymakers need to address the influence of global deforestation and urbanization on climate change, in addition to greenhouse gas emissions.

October Third Coolest, Wettest on Record, Across US
November 11, 2009 07:00 AM - Roger Greenway, ENN

The National Oceanic and Atmospheric Administration reported that, on average, the mainland US (excluding Alaska) was the third coolest on record, and the records go back to 1895 at some stations. Average temperatures were 4.0 degrees F below the long term average. Rainfall average was 4.15, twice the long term average of 2.04 inches.

Olympic Torch Run May Shine Light on Polar Bear Plight

As the Olympic torch continues its journey through Canada's north, some scientists are hoping it will shine an international light on the plight of the country's iconic mammal - the polar bear. Environmentalists warn the symbol of the North is in grave danger because of climate change, yet neither Canadians, nor anyone from the international community has proposed anything concrete to save them.

Glacier Retreat in Antarctica Has Unexpected Benefit
November 10, 2009 06:53 AM - Roger Greenway, ENN

The British Antarctic Survey (BAS) has been studying glaciers in Antarctica, looking at their reducing surface area. As the glaciers retreat, more open water is exposed, and lead author of a new study, Professor Lloyd Peck of the BAS found that large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonization is having a beneficial impact on climate change. The phytoplankton blooms are relatively short lived, and as they die back, phytoplankton sinks to the sea-bed where it can store carbon for thousands or millions of years.

Heat-Related Nitrogen Loss Endangers Desert Plant Life
November 9, 2009 04:38 PM - Krishna Ramanujan, Cornell Chronicle

As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. This could lead to deserts with even less plant life than they sustain today, say the researchers. Available nitrogen is second only to water as the biggest constraint to biological activity in arid ecosystems, but before now, ecologists struggled to understand how the inputs and outputs of nitrogen in deserts balance.

Hurricane Ida Approaches US Gulf Coast

Hurricane Ida continues to move north towards the US Gulf Coast this morning. At 3am it was in the central part of the Gulf of Mexico, moving north-northeastward at 16 mph.
