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 ”˜linear’ 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 ”˜non-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.

Bodies of Miskito Indians killed by Hurricane Felix floated in the Caribbean off Central America and washed up on beaches on Thursday as the death toll from the storm rose to over 60. Many of the dead were traveling by boat when they were hit by huge waves as Felix struck near the border between Honduras and Nicaragua on Tuesday as a giant Category 5 storm.
APEC officials agree on global warming statement
September 7, 2007 07:24 AM - Associated Press
SYDNEY (AP): Pacific Rim nations on Friday reached agreement on a joint statement on global warming, overcoming bickering between rich and poor nations about whether to include targets on emissions, two Asian officials said. Experts from the 21-member Asia Pacific Economic Cooperation forum approved the wording of a final draft statement on climate change that would be handed to leaders at their summit starting Saturday, the officials said.
Carving Out a New Idea of the Past

There was bad news and good news aboard the U.S. Coast Guard icebreaking vessel Healy during a voyage to the Arctic Ocean. The bad news was a disturbing lack of sea ice, which, combined with strong winds, prevented the vessel from maintaining a steady position in the Arctic's Chukchi Sea. But the good news was that the ice-free seas gave the researchers a rare opportunity to make intricately detailed maps of the region's seafloor.
NOAA study backs up predictions of sea ice loss
September 7, 2007 07:07 AM - Associated Press
Sea ice loss in regions of the Arctic is likely to exceed 40 percent by 2050 compared with the 1980s, according to an analysis of ice computer models by researchers at the National Oceanic and Atmospheric Administration.
Bush presses Asia-Pacific on trade and climate
September 7, 2007 06:53 AM - Matt Spetalnick and Caren Bohan -Reuters
U.S. President George W. Bush urged the Pacific Rim's economic powerhouses on Friday to help secure elusive global deals on trade and climate change and pledged an "unshakeable" commitment to the region's security.
Bush shows gift of gaffe at APEC summit
September 7, 2007 06:47 AM - Reuters
Even for someone as gaffe-prone as U.S. President George W. Bush, he was in rare form on Friday, confusing APEC with OPEC and transforming Australian troops into Austrians. Bush's tongue started slipping almost as soon as he started talking at a business forum on the eve of an Asia-Pacific Economic Cooperation (APEC) summit in Sydney.
Typhoon batters Tokyo, moves on

A typhoon pounded Tokyo and surrounding areas on Friday, killing at least one man and snarling transport and power supplies, before weakening and moving north. The typhoon, the biggest to hit Tokyo since October 2002, brought down record rainfall in many parts of the capital, but by afternoon it had weakened to a tropical storm.
