U.S. West warming faster than rest of world: study
March 27, 2008 09:04 PM - Reuters
LOS ANGELES (Reuters) - The U.S. West is heating up at nearly twice the rate of the rest of the world and is likely to face more drought conditions in many of its fast-growing cities, an environmental group said on Thursday. By analyzing federal government temperature data, the Natural Resources Defense Council concluded that the average temperature in the 11-state Western region from 2003-07 was 1.7 degrees Fahrenheit (0.94 degrees Celsius) higher than the historical average of the 20th century.
Ice shrink in Arctic sea may attract oil firms
March 26, 2008 08:17 AM - Reuters
OSLO (Reuters) - Winter sea ice around a Norwegian Arctic island has thinned to less than one meter (3 feet) since the 1960s, according to a study on Tuesday of a region that may be more attractive to oil firms because of climate change. The Norwegian Polar Institute said ice around Hopen island southeast of the Svalbard archipelago had become more than 40 cms (16 inches) thinner in the past 40 years, in what it called the first long-term study of ice thickness in the Barents Sea.
Slab of Antarctic ice shelf collapses amid warming

WASHINGTON (Reuters) - Satellite images show that a large hunk of Antarctica's Wilkins Ice Shelf has started to collapse in a fast-warming region of the continent, scientists said on Tuesday. The area of collapse measured about 160 square miles of the Wilkins Ice Shelf, according to satellite imagery from the University of Colorado's National Snow and Ice Data Center.
Australian wine industry feels heat from climate change
March 25, 2008 08:18 AM - Reuters
MELBOURNE (Reuters) - Australian grape growers reckon they are the canary in the coalmine of global warming, as a long drought forces winemakers to rethink the styles of wine they can produce and the regions they can grow in. The three largest grape-growing regions in Australia, the driest inhabited continent on earth, all depend on irrigation to survive. The high cost of water has made life tough for growers.
Black carbon pollution emerges as major player in global warming
March 24, 2008 09:31 AM - University of California - San Diego
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal Nature Geoscience. Scripps Institution of Oceanography at UC San Diego atmospheric scientist V. Ramanathan and University of Iowa chemical engineer Greg Carmichael, said that soot and other forms of black carbon could have as much as 60 percent of the current global warming effect of carbon dioxide, more than that of any greenhouse gas besides CO2.
Melting glaciers will shrink grain harvests in China and India.
March 21, 2008 09:36 AM - Lester Brown, Earth Policy Institute
The world is now facing a climate-driven shrinkage of river-based irrigation water supplies. Mountain glaciers in the Himalayas and on the Tibet-Qinghai Plateau are melting and could soon deprive the major rivers of India and China of the ice melt needed to sustain them during the dry season. In the Ganges, the Yellow, and the Yangtze river basins, where irrigated agriculture depends heavily on rivers, this loss of dry-season flow will shrink harvests.
Icy start, but 2008 may be in top 10 warmest years
March 19, 2008 09:24 AM - Reuters
OSLO (Reuters) - After the coldest start to a year in more than a decade, spring will bring relief to the northern hemisphere from Thursday. Bucking the trend of global warming, the start of 2008 saw icy weather around the world from China to Greece. But despite its chilly start, 2008 is expected to end up among the top 10 warmest years since records began in the 1860s.
Aid needed to help China make carbon cuts
March 18, 2008 09:28 AM - , SciDevNet
nternational carbon funds should be aggressively directed towards helping China avoid the use of carbon-rich technologies, say Ning Zeng and colleagues in this Science article. Action is needed despite significant gains in energy efficiency, they note, because based on current economic growth rates and levels of carbon intensity (emissions per unit of gross domestic product) China's emissions by 2030 will equal today's entire global output.
Vanishing central African glaciers threaten water supplies of millions
March 18, 2008 09:13 AM - WWF
Nairobi, Kenya — Nairobi, Kenya — Forget the snows of Kilimanjaro — Africa is at risk of losing the central African glaciers that feed the Nile and supply water to two million people. A WWF and partner organization team of 27 people of eight nationalities recently returned from the Rwenzori Mountains after gathering data showing that the mountain's glaciers have shrunk by 50 per cent in the last 50 years and more than 75 per cent in the last century.
Japan to host climate change summit
March 18, 2008 03:02 AM - Reuters
TOKYO (Reuters) - Leaders from 16 countries including the Group of Eight (G8), China, India and Brazil will gather to discuss climate change on the sidelines of the G8 summit in July, Japan's top government spokesman said on Tuesday. Global warming is at the top of the agenda for the G8 summit and host country Japan is inviting the leaders of Australia, Brazil, China, India, Indonesia, South Korea, South Africa and Mexico to attend an expanded gathering on the topic on July 9, Chief Cabinet Secretary Nobutaka Machimura told a news conference.
