NASA scientists have developed a new climate model that indicates that the most violent severe storms and tornadoes may become more common as Earth’s climate warms.

BEIJING - A huge swathe of China's booming Pearl River Delta will be "engulfed" by rising sea water by the middle of the century because of global warming, state media said on Thursday, quoting weather officials. Some 1,153 square km (445 square miles) of coastal land would be flooded by 2050, with the bustling cities of Guangzhou, capital of Guangdong province, Zhuhai and Foshan the worst affected, the China Daily said, quoting the provincial water authority.

New U.S. Test: CO2 Could Make Grasslands 'Unusable'

Increasing atmospheric carbon dioxide levels could change the nature of grasslands and decrease their usefulness as grazing pastures, say researchers. The study was published in the journal Proceedings of the National Academy of Sciences this week (27 August). If carbon dioxide levels in the atmosphere continue to rise, important grazing areas in parts of Africa, Kazakhstan, Mexico, Mongolia, and southern and South East Asia could be under threat, according to lead author Jack Morgan, a plant physiologist from the US Department of Agriculture's Agricultural Research Service.

Study: Experts’ Forecasts Sometimes Fall Short

A study about predicting the outcome of actual conflicts found that the forecasts of experts who use their unaided judgment are little better than those of novices, according to a new study in a publication of the Institute for Operations Research and the Management Sciences. When presented with actual crises, such as a disguised version of a 1970s border dispute between Iraq and Syria and an unfolding dispute between football players and management, experts were able to forecast the decisions the parties made in only 32% of the cases, little better than the 29% scored by undergraduate students. Chance guesses at the outcomes would be right 28% of the time.

Mankind to blame for warming but can slow damage
August 29, 2007 08:57 AM - Alister Doyle - Reuters

Mankind is to blame for climate change but governments still have time to slow accelerating damage at moderate cost if they act quickly, a draft U.N. report shows. Underlining the need for speed, it says a European Union goal of holding temperature rises to a maximum 2 Celsius (3.6 Fahrenheit) above pre-industrial times is almost out of reach. The 21-page study, due for release in November, lays out possible responses to global warming but cautions that some impacts are already inevitable, such as a gradual rise in sea levels that is set to last for centuries.

Warming caused by human activity was the biggest factor in unusually high temperatures recorded in 2006 in the United States, according to a report by researchers at the National Oceanic and Atmospheric Administration.

Tribal people in India's remote northeast plan to honour former U.S. Vice President Al Gore with an award for promoting awareness on climate change that they say will have a devastating impact on their homeland.

U.N. says climate deal in 2009 ideal, but complex
August 29, 2007 08:02 AM - Alister Doyle - Reuters

The U.N.'s top climate official said on Tuesday that agreeing a global deal by the end of 2009 to combat climate change would be ideal but noted much needs to be done. "There is this sense of urgency, we do need to get it completed as quickly as possible," Yvo de Boer told Reuters on the fringe of talks on global warming grouping 158 nations. Many experts say 2009 is the latest practical date to agree a climate pact to succeed the Kyoto Protocol beyond 2012. Any firm building a coal-fired power plant or a wind farm needs to know rules for greenhouse gas emissions years in advance.
