Rice yields, the agricultural staple of Southeast Asia, will be hit particularly hard with the region suffering a 50 percent decline in rice yields by 2100. The Philippines would see the worst decline with a 75 percent loss in its rice fields.

Assistant chief economist at ADB, Juzhong Zhuang told Reuters that these nations “need regional-level activity and it is needed now. If the action is delayed then south-east Asia will suffer much more than most other regions of the world. What's needed is better government policy, better co-ordination between agencies and between central and local government, and better research by all countries."
Most of Southeast Asia’s carbon emissions are due to deforestation instead of the burning of fossil fuels. Eighty percent of Indonesia’s emissions, for example, are due to deforestation and conversion of peat lands, largely for palm oil plantations. Worldwide deforestation accounts for nearly 20 percent of emissions.
Cutting greenhouse gases now would save world from worst global warming scenarios
(04/14/2009) If nations worked together to produce large cuts in greenhouse gases, the world would be saved from global warming's worst-case-scenarios, according to a new study from the National Center for Atmospheric Research (NCAR). The study found that, although temperatures are set to rise this century, cutting greenhouse gases by 70 percent the globe could avoid the most dangerous aspects of climate change, including a drastic rise in sea level, melting of the Arctic sea ice, and large-scale changes in precipitation. In addition such cuts would eventually allow the climate to stabilize by the end of the century rather than a continuous rise in temperatures.
Global warming will hit corn yields, costing US over a billion dollars annually
(04/10/2009) Corn is the staple crop of the US. Its annual yield is more than twice that of any other American crop, covering an astounding 125,000 square miles. However, this behemoth crop is currently threatened. A new analysis by Environment America, shows that lower yields of corn due to global warming will cost farmers 1.4 billion every year.
CO2 levels rise to a new record
(02/17/2009) Atmospheric carbon dioxide concentrations climbed 2.28 parts-per-million (ppm) in 2008 to the highest level in at least 650,000 years — and possibly 20 million years — reports NOAA.
