In order to see what effect the change in land surface had on the climate, the researchers (of which two are MERGE-researchers; Marie-Jose Gaillard from Linnaeus University and Johan Lindström from Lund University) led by Gustav Strandberg (SMHI) looked at reconstructions of the land surface derived from analysis of thousands of years-old pollen grains preserved in lake sediments. Using a vegetation model, they also simulated what the land surface would have looked like around 500 BC without human influence. The researchers then used global and regional climate models developed at SMHI to simulate Europe's climate, both as it was, according to the pollen data, and as it would have been without human influence, in order to make comparisons.
