4 of global warming will cause the calamitous consequence
News from Xinhua News Agency the purpose of negotiation of climate of the United Nations is to turn the whole world into the warm range to limit to 2 , but some researchers warn and say, if does not take the strong measure, intensifying the range will probably reach 4 within this century, this will bring the calamitous consequence in migrating etc. largely in agriculture, water resource, population.

Britain " Royal Society's philosophical journal " released a monograph on November 29, gathered multinational researchers' thesis, concentrate on discussing possibility and consequence of 4 global warming. The research of Richard and Bates of the British weather bureau,et al. is thought, though the goal of the international community is to compares and does not exceed 2 the increasing degree control of the temperature with industrial revolution within this century now, but in terms of situation at present, a plurality of prediction models reveal the increasing degree of the temperature may reach 4 within this century, in the worst prediction, even may intensify the range in about 2060 and reach 4 .

The warm range, bring the disaster to the ecosystems of a lot of places while being such a. Philip of Kenya Thornton waits for someone to think, the agriculture of Africa will suffer the serious blow to the south of the Sahara, some is no longer effective to intensifying 2 counter-measure, some place existing agricultural systems will suffer heavy losses different to retrieve, bring the food safety question.

Remind and say, the global water resource is bearing the double pressures of population growth and climatic change in knob of mark of Oxford University,et al.. Present population forecast is to top 90 hundred million by 2050, may drop slowly subsequently, if the global warming is too fast, in the prediction picture of 4 of increasing degree, the peak value of population, with turning into warm peak value and presenting overlapping, make the water resource can't bear the heavy load to use. If can limit the increasing degree of the temperature to 2 within this century, certain leeway go on the peak is regulated by mistake.

Consequence that the people whose kindness has specially analyzed the global warming brings of one dose of plums of French researcher Francois migrate. He says, in intensifying the prediction of 2 , mainly population appears to migrate because the sea level rises in the coastal area and island Congress, but in intensifying the prediction of 4 , scale and property that population migrates will all change more seriously.

Some other researcher change from forest also and ice sheet melt analyze the intersection of global warming and serious consequence that 4 might bring in many aspects, and corresponding counter-measure. (yellow)
