The processes controlling the carbon flux and carbon storage of the atmosphere, ocean and terrestrial biosphere are temperature sensitive. Those are likely to provide a positive feedback leading to amplified anthropogenic warming as suggested by recent studies.

Coca-Cola Co said that it will eliminate hydrofluorocarbon gas in its new vending machines.Coke's 10 million vending machines, coolers and other refrigeration equipment around the world are the biggest contributor to the company's carbon footprint.  Coke and its bottling partners will buy 150,000 units of HFC-free equipment in 2010, which is said to be an equivalent of takin

A recent reaserch article in the journal Nature show that monsoon rainfall in East Africa varied at half-precessional (~11,500-year) intervals, because the southeasterly and northeasterly Indian Ocean monsoons, which together create the bimodal seasonal distribution of equatorial rainfall, were strengthened in alternation when the inter-hemispheric insolation gradient was maximized.

World's top emitter of greenhouse gases China together with India, Brazil and South Africa rejected core targets for a climate deal such as halving world greenhouse gas emissions by 2050 and demanded that richer nations do more. A legally binding deal is already out of reach for the U.N. talks that only expect a possible political deal.

The U.N. Population Fund (UNFPA) report on climate change shows that fifteen percent of people in the Arab world already have limited or no access to potable water.

Climate change is likely to bring more rain to China's northeastern bread basket, but too late in the year to benefit crops, seriously threatening a major region for wheat, corn and rice as reported in "From bread basket to dust bowl". The report highlights how complicated the impact of climate change may be in many areas, and also the threats it poses to China's food supplies.

The Amazon, a fifth of which is already destroyed, accounts for more than half of the world's standing forest and an estimated 55 percent of Brazil's greenhouse gas emissions.
