Many of the effects of global warming have been well-documented. It is the precise extent that is difficult to predict.Ministry of Climate and Energy of DenmarkPredicting the consequences of global warming is one of the really difficult tasks for the worlds climate researchers. Firstly, because the natural processes that cause precipitation, storms, increases in sea level and other expected effects of global warming are dependent on many different factors. Secondly, because it is difficult to predict the size of the emissions of greenhouse gases in the coming decades, as this is determined to a great extent by political decisions and technological breakthroughs. Many of the effects of global warming have been well-documented, and observations from real life are very much consistent with earlier predictions. It is the precise extent that is difficult to predict. Among the effects that can be predicted are:More droughts and more flooding:When the weather gets warmer, evaporation from both land and sea increases. This can cause drought in areas of the world where the increased evaporation is not compensated for by more precipitation. The extra water vapor in the atmosphere has to fall again as extra precipitation, which can cause flooding other places in the world.Less ice and snow:Glaciers are shrinking rapidly at present. The trend is for the ice to melt faster than estimated in the IPCCs latest report. In areas that are dependent on melt water from mountain areas, this can cause drought and a lack of drinking water. According to the IPCC, up to a sixth of the worlds population lives in areas that will be affected by this.More extreme weather incidents:The warmer climate will most probably cause more heatwaves, more cases of heavy rainfall and also possibly an increase in the number and/or severity of storms.Rising sea level:The sea level rises for two reasons. Partly because of the melting ice and snow, and partly because of the thermal expansion of the sea. Thermal expansion takes a long time, but even an increase in temperature of two degrees Celsius is expected, in due time, to cause a rise in the water level of almost a metre.In order to get an idea of the extent of the consequences, researchers typically work with scenarios that show various possible developments.

Now, he goes into details with his vision for a fund. "The climate change adaptation fund has to be created by mandatory contribution of developed countries as over and above their usual overseas development assistance fund," Hasan Mahmud told at a press conference, according to Asia News Network. Mahmud, who is leading the Bangladesh delegation at the UN climate change conference in Copenhagen, stressed that more or less one billion people are affected
