Global warming greatest in past decade
September 2, 2008 08:57 AM - Penn State
Researchers confirm that surface temperatures in the Northern Hemisphere were warmer over the last 10 years than any time during the last 1300 years, and, if the climate scientists include the somewhat controversial data derived from tree-ring records, the warming is anomalous for at least 1700 years.

The world should not wait until next year to cobble together a new climate change pact, United Nations Secretary-General Ban Ki-moon said on Sunday. Ban, addressing diplomats and officials at a ceremony for the 20th anniversary of the U.N. climate panel, said countries negotiating a successor deal to the Kyoto Protocol should aim for a meaningful breakthrough in Poznan, Poland, in December.
Arctic ice on the verge of another all-time low
August 28, 2008 11:00 AM - European Space Agency
Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. The animation above is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced Synthetic Aperture Radar (ASAR) instrument aboard Envisat. The dark grey colour represents ice-free areas while blue represents areas covered with sea ice.

Lord Smith, the new head of the Environment Agency, this week gave a cautionary warning to the government over the folly of continuing with climate damaging super projects like the third runway at Heathrow, and the proposed new coal power station at Kingsnorth in Kent. He also highlighted the threat that climate change induced sea level rises and coastal erosion will have on the UK’s coast line and that tough choices would have to be made over whether to defend threatened communities.
Receding Arctic icepack opens new shipping frontier

BARROW, Alaska -- Rapidly melting ice on Alaska's Arctic is opening up a new navigable ocean in the extreme north, allowing oil tankers, fishing vessels and even cruise ships to venture into a realm once trolled mostly by indigenous hunters.
U.S. says states can lift emission monitoring bar
August 21, 2008 10:03 AM - Reuters
(Reuters) - A U.S. federal court on Tuesday overturned a rule that prevented state and local authorities from raising emissions monitoring requirements for polluting units such as chemical plants and oil refineries. Regulatory body Environmental Protection Agency (EPA) had added a rule to the existing Clean Air Act in 1990 that prevented authorities from adding to monitoring requirements.
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.
