Description
Summary:Even the economical crisis was not strong enough to deflect theanthropogenic greenhouse gas forcing for more than one year. It tends to developat the upper edge of the IPCC (2007) projection band of uncertainties. The part ofthe emitted carbon dioxide remaining in the atmosphere is increasing due toweakening of both the biospheric- and the oceanic sinks of this greenhouse-gas.The new radiation balance estimations must admit the imbalance between theatmosphere and the oceans indicating the fact that the greenhouse warmingdefinitely takes place. The year 2010 became most likely the warmest one on theglobal temperature record. The sea-level rise also follows the most rapid trackamong the foreseen scenarios. In the meantime modelling effort to better estimateregional features of the changes also develop in their full strength. TheENSEMBLES Project ended in December 2009 and published a lot of maps with25 km model resolution. These results, however, do not show convergence in theestimations for many regions, including Central Europe, either.
