Scientists Suggest New Arctic Study May Oversate Sea Ice Melting
October 17, 2009 11:55 AM - Thomas Schueneman, Global Warming is Real

Cambridge professor Peter Wadhams made headlines yesterday when he said that data gathered from British explorer Pen Hadlow's Arctic trek, called the Catlin Ice Survey, shows that Arctic summers will be entirely ice-free by 2020. Today, many experts fear the Wadhams may be overstating just how fast the Arctic will be open ocean in summer.

Spotted Seals near Alaska Denied NOAA Protection

NOAA’s Fisheries Service announced yesterday that two of three populations totaling more than 200,000 spotted seals in and near Alaska are not currently in danger of extinction or likely to become endangered in the foreseeable future. The announcement follows an 18-month status review. However, NOAA is proposing to list a third smaller population of 3,300 seals off China and Russia as threatened.

U.S. Climate Plan will Boost Nuclear, Renewables

A U.S. cap-and-trade market on greenhouse gases should be designed carefully to avoid unfair economic pain in fossil fuel industries and other parts of the economy, experts told lawmakers on Wednesday. The aim of a cap-and-trade market on greenhouse gases at the center of the climate bill introduced by Senate leaders this month would transform the economy from being based on fossil fuels to more nuclear and renewable power.

George Soros Pledges $1.1 Billion to Fund Climate Change Initiatives

Philanthropist and businessman George Soros announced this week that he would be the next in a line of wealthy front-runners to fund initiatives in clean technology. Soros is the founder of hedge fund Soros Fund Management LLC, and has been known for making monetary contributions to other charitable efforts that effect the well-being of society, such as health care and eduction; now he’s shifting his focus to play a part in reducing the impact of climate change.

Getting Greener May Cost Us Less Than We Think

Cutting greenhouse gases along the lines of a climate bill pending in Congress would modestly impact the US economy over the next few decades, the bipartisan Congressional Budget Office (CBO) said Wednesday in a report.

Global Warming Threatens to Upset Arctic Carbon Trapping
October 15, 2009 06:35 AM - R. Greenway, ENN

The US Geological Survey, in partnership with the Ecological Society of America, University of Alaska Fairbanks published the results of a study on the changing climate and the important role that the Arctic plays in sequestering carbon. The study shows that the arctic could potentially alter the Earth’s climate by becoming a possible source of global atmospheric carbon dioxide.

Secret to Slowing Global Warming Lies Beneath the Waves
October 14, 2009 02:46 PM - Frank Pope, The Times, Environmental Health News

Life in the ocean has the potential to help to prevent global warming, according to a report published today. Marine plant life sucks 2 billion tons of carbon dioxide from the atmosphere every year, but most of the plankton responsible never reaches the seabed to become a permanent carbon store. Mangrove forests, salt marshes and seagrass beds are a different matter. Although together they cover less than 1 percent of the world’s seabed, they lock away well over half of all carbon to be buried in the ocean floor. They are estimated to store 1,650 million tons of carbon dioxide every year — nearly half of global transport emissions — making them one of the most intense carbon sinks on Earth. Their capacity to absorb the emissions is under threat, however: the habitats are being lost at a rate of up to 7 per cent a year, up to 15 times faster than the tropical rainforests. A third have already been lost.

New Research Suggests Conservation Biologists are Setting Minimum Population Size Targets Too Low to Prevent Extinction
October 13, 2009 02:41 PM - Vanessa L. Bourlier, ENN

A new study by University of Adelaide and Macquarie University (Australia) scientists has shown that populations of endangered species are unlikely to persist in the face of global climate change and habitat loss unless they number around 5,000 mature individuals or more.

Climate no longer top policy issue with Australians

Australian voters no longer see the environment as the top policy issue, but the government remained committed Tuesday to an emissions trading scheme which, if defeated in November, could see a snap election.

Kashmir's main glacier "melting at alarming speed"
October 12, 2009 02:01 PM - Reuters

Indian Kashmir's biggest glacier, which feeds the region's main river, is melting faster than other Himalayas glaciers, threatening the water supply of tens of thousands of people, a new report warned on Monday.
