The California Air Resources Board said on Friday it would step up the pace of new regulations to fight global warming in the most populous U.S. state. The air board also added measures that go beyond the requirements of California's 2006 landmark law to reduce carbon dioxide and other greenhouse gas emissions by 25 percent by 2020.

APEC leaders agree climate change pact at summit

Asia-Pacific leaders agreed on Saturday to adopt a "long-term aspirational goal" to reduce greenhouse gas emissions, Australian Prime Minister John Howard said. Howard said 21 Asia-Pacific leaders meeting in Sydney agreed on the need for all nations, developing and developed, to contribute according to their own capacities and circumstances to reducing greenhouse gases.

Shipping industry needs global emmisions regulation
September 8, 2007 06:37 AM - Reuters

The world's shipping industry needs global regulations that are consistently enforced by the United Nations if it is to cut emissions, the chairman of the International Chamber of Shipping said on Friday. Public pressure is building for ship owners to curb air pollution and take part in markets in permits to emit sulfur and greenhouse gases.

NOAA: Arctic Regional Sea Ice To Decline 40 Percent Before 2050
September 7, 2007 05:51 PM - NOAA News

WASHINGTON - A new study by NOAA scientists shows that areal sea-ice coverage of the Arctic Ocean will decline by more than 40 percent before the summer of 2050, compared to a 1979-1999 base period. These findings are based upon a study of national and international computer models that closely match the observed sea-ice extent over the 20-year baseline period of 1979-1999, and then project forward in time to determine any changes.

NOAA Experts: La Nina Is Coming
September 7, 2007 05:35 PM - NOAA News

WASHINGTON - Scientists with NOAA’s Climate Prediction Center say that La Nina is on its way in today’s release of the monthly El Nino/Southern Oscillation Diagnostic Discussion. “While we can’t officially call it a La Nina yet, we expect that this pattern will continue to develop during the next three months, meeting the NOAA definition for a La Nina event later this year,”Ł said Mike Halpert, acting deputy director of the Climate Prediction Center in Camp Springs, Md.

Tipping Points In Earth System, Not Always Smooth
September 7, 2007 03:05 PM - Timothy M. Lenton, U of East Anglia

University of East Anglia - The Intergovernmental Panel on Climate Change in its many excellent reports tends to portray climate change as a smooth transition. Although the projections are rarely straight lines the underlying system and its responses appear ”ślinear’ in mathematical terms. There are, of course, exceptions to this, notable ones being the possible collapse of the Atlantic thermohaline circulation or irreversible melt of the Greenland ice sheet, which both get significant attention in the latest IPCC report. These represent large scale ”śnon-linear’ components of the Earth system.

APEC draft climate statement seen a compromise
September 7, 2007 02:34 PM - Jalil Hamid -Reuters

Asia-Pacific officials agreed on Friday to a draft climate statement which reaffirms a U.N. treaty on fighting global warming, while urging non-binding "aspirational targets" for greenhouse gas reductions, a delegate said. But the climate statement, which has emerged after tough negotiations following a split between developing and developed members of the Asia Pacific Economic Cooperation (APEC) forum, remains to be agreed to by the 21 Asia-Pacific leaders.

New Research Identifies How One Storm Can Affect Another
September 7, 2007 01:48 PM - University of Leeds

Weather forecasting and climate modelling for the notoriously unpredictable Sahel region of Africa could be made easier in the future, thanks to new research results coming from the African Monsoon Multidisciplinary Analysis study (AMMA). University of Leeds - A paper published in Geophysical Research Letters describes how the AMMA scientists gathered new atmospheric data by using satellite imagery to plot flight paths over areas where storms had produced very wet soils. Dropsondes (weather reconnaissance devices) were launched from a research aircraft above these wet areas to record data such as humidity, wind strength and temperature. The findings allowed the scientists to compare the atmospheric conditions above wet soils with those above adjacent dry soils.
