全球变暖再度加剧
地球暖化的速度比联合国跨政府气候变迁小组（IPCC,Intergovernmental Panel on Climate Change）在2007年预估的更快，气温上升已导致谷物歉收，森林和海洋天然碳汇的碳吸收量也比预期的少。
An independent scientific reviews says the projected causes of the carbon with the impact of the climate change are likely to be one or three times greater than the current United Nation's estimates. The researchers put the properble annual bill of dealing with wrestling floods, draught and storms at 2 or 3 hundred billion dollars. Richard Black reports
There is a large amount of what you might call estimation involved an always assessment. we don't know for sure the scale of climate threads. How much sea levels will rise, how much will the changes affect crop ills and so on. And we don't know for sure how much combating these impacts would cost. The UN admitted the estimates were cautious. The number are very important politically, the developing countries say western economics have caused the climate change and western economics must pay for these protections measures. Without the money, there won't be a deal at the UN climate talk in Copenhagen later this year
