Arctic Thaw May be at "Tipping Point"
September 28, 2007 08:57 AM - Reuters
OSLO- A record melt of Arctic summer sea ice this month may be a sign that global warming is reaching a critical trigger point that could accelerate the northern thaw, some scientists say. "The reason so much (of the Arctic ice) went suddenly is that it is hitting a tipping point that we have been warning about for the past few years," James Hansen, director of NASA's Goddard Institute for Space Studies, told Reuters. The Arctic summer sea ice shrank by more than 20 percent below the previous 2005 record low in mid-September to 4.13 million sq km (1.6 million sq miles), according to a 30-year satellite record. It has now frozen out to 4.2 million sq km.
Tropical Storm Lorenzo Lashes Mexico's Gulf Coast

MEXICO CITY (Reuters) - Lorenzo was downgraded to a tropical storm over Mexico on Friday hours after it swept ashore as a Category 1 hurricane, dumping heavy rain on the already waterlogged state of Veracruz. Lorenzo lost force after it made landfall near the Gulf of Mexico port city of Tuxpan, and its maximum wind speed had dropped to 65 mph (100 kph) by 5 a.m. EDT (0900 GMT), the U.S. National Hurricane Center said. The storm was not seen affecting Mexico's oil production but around 100,000 people living between Tuxpan and the town of Nautla further south were evacuated to storm shelters.
Bush Called "Isolated" , Leadership Questioned, At Climate Talks

WASHINGTON - U.S. President George W. Bush kicks off the second day of a conference on global warming on Friday under pressure from the world's major economies to accept binding limits on emissions of greenhouse gases. Bush called the meeting as a precursor to United Nations talks in Bali in December, which will aim to launch a successor to the Kyoto Protocol, a treaty that set limits on industrial nations' emissions. Environmentalists said the conference produced nothing new and was an attempt to circumvent U.N. efforts on climate change, a charge Secretary of State Condoleezza Rice denied.
NOAA to Provide More Specific Warning Information for Severe Weather
September 27, 2007 06:35 PM -
SILVER SPRING, Md. - NOAA's National Weather Service will begin issuing more geographically specific warnings for tornadoes, severe thunderstorms, floods, and marine hazards starting October 1. The new "storm-based warnings" will allow forecasters to pinpoint the specific area where the threats are highest, reducing the area warned by as much as 70 percent when compared to today's county-by-county system.
Tropical Storm Lorenzo heads for Mexico

MEXICO CITY (Reuters) - Tropical Storm Lorenzo formed in the Gulf of Mexico on Thursday and headed for the Mexican coast but was unlikely to affect oil production in the area.
Lorenzo will probably hit the coastline on Friday in the state of Veracruz. It had wind speeds of 60 mph (95 kph) and showed no sign of reaching hurricane strength.
"No significant change in strength is forecast during the next 24 hours" the U.S. National Hurricane Center said.

LONG BEACH, California (Reuters) - Two of the nation's biggest power companies are teaming up with a solar start-up to create one of the world's largest solar power projects, which they say could make electricity at a competitive price.
PG&E Corp, FPL Corp and solar thermal power generator Ausra Inc unveiled plans on Thursday for utility-scale solar plants which they claim will produce electricity at a price comparable with conventional fossil-fuel power plants.
Impact of Arctic heat wave stuns climate change researchers
September 27, 2007 08:24 AM - Queen's University
Unprecedented warm temperatures in the High Arctic this past summer were so extreme that researchers with a Queen’s-led climate change project have begun revising their forecasts.
“Everything has changed dramatically in the watershed we observed,” reports Geography professor Scott Lamoureux, the leader of an International Polar Year project announced yesterday in Nunavut by Indian and Northern Affairs Minister Chuck Strahl. “It’s something we’d envisioned for the future – but to see it happening now is quite remarkable.”
Gaia Guru Urges Ocean Pipes To Fix Earth's Climate

LONDON - A series of giant pipes in the oceans to mix surface and deeper water could be an emergency fix for the Earth's damaged climate system, the scientist behind the Gaia theory said on Wednesday.
EU Struggles To Walk Its Talk On Climate Change
September 27, 2007 07:37 AM - Reuters
UNITED NATIONS - The European Union pressed world leaders this week to follow its lead in fighting climate change, but a battle looms at home over how to share the burden of cutting greenhouse gas emissions. The EU in March agreed to cut emissions blamed for global warming by 20 percent by 2020 compared to 1990 levels and 30 percent if the rest of the world joins in. European leaders such as German Chancellor Angela Merkel urged their counterparts at the United Nations to follow suit.
U.S. Climate Talks Draw World's Biggest Polluters

WASHINGTON - The world's biggest greenhouse gas polluters -- including the United States and China -- sent envoys to the U.S. State Department on Thursday for discussions on climate change and what to do about it. The two-day meeting was called by President George W. Bush, whose administration has been criticized for its refusal to adopt mandatory limits for climate-warming emissions. The White House favors "aspirational" targets.
