• Black carbon pollution emerges as major player in global warming

    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. >> Read the Full Article
  • What Bali means for China

    China played a critical negotiating role in the fraught UN climate summit in Bali. Its next challenge is to satisfy the demands of the world’s media. The UN climate summit in Bali, Indonesia, in December 2007 will probably be best remembered for the executive secretary, Yvo de Boer, dramatically walking out of the conference hall in tears. In less dramatic but more important ways China significantly advanced the negotiations, with huge implications for global efforts to tackle climate change. And it also learnt an important lesson about itself. >> Read the Full Article
  • Landless and exposed to the elements

    Uganda’s Batwa communities have been marginalised for decades. Now they are struggling to cope with extreme weather conditions, and want better homes to protect them from storms and landslides. Among the posh office premises of the Red Cross Society and the court of adjudicature on Muchingo hill, in Uganda's western district of Kisoro, are ramshackle houses in which a community of Batwa people live. >> Read the Full Article
  • Melting glaciers will shrink grain harvests in China and India.

    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. >> Read the Full Article
  • Icy start, but 2008 may be in top 10 warmest years

    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. >> Read the Full Article
  • Aid needed to help China make carbon cuts

    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. >> Read the Full Article
  • Vanishing central African glaciers threaten water supplies of millions

    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. >> Read the Full Article
  • Japan to host climate change summit

    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. >> Read the Full Article
  • Lehman sees U.S. climate move to spur carbon trade

    TOKYO (Reuters) - Signs the United States will soon respond to global warming and a new climate pact now under discussion are set to drive the carbon market further in the next two years, Lehman Brothers said on Monday. Several states in the United States, the world's biggest emitter of carbon dioxide, have recently moved to choose carbon trading, instead of carbon taxation, paving the way for Washington to take similar moves. >> Read the Full Article
  • DoT releases study of climate change and effects on Gulf Coast transportation

    The U.S. Dept. of Transportation (DoT) on Wednesday released a study of the potential impacts climate change and land subsidence could have on the Gulf Coast region's transportation infrastructure. Examining an area that includes 48 contiguous counties in four states - from Galveston, Texas to Mobile, Alabama – the DoT has undertaken the study to provide valuable information to regional transportation planners and government. The report is the first of a three-phase study on a region of particular concern given its geography, ecology and vulnerability, as well as the central role it plays in the nation's oil and gas infrastructure. >> Read the Full Article
