Proposal General Summary Global warming has occurred over the last 100 years or so, almost certainly as result of increased atmospheric concentrations of greenhouse gases due to anthropogenic activity. The starting point for the climate reconstructions in the EIP will be an extended and enhanced gridded monthly mean sea-level pressure dataset. This will allow an objective assessment of variability over the full 215 years of the EIP and the MIP combined, and an indication of whether or not circulation modes were different before, and during, the period of anthropogenic influence. In the early decades of the EIP, documentary data will be used to reconstruct monthly climatic patterns and, for the first time, objective assessments will be conducted through comparison with the instrumental data based reconstructions, and appropriate tree-ring data.
European climate is linked to surface conditions in the North Atlantic Ocean.
