A pioneering effort by research groups co-operating across the world has resulted in comprehensive insights into future impacts of climate change ranging from water scarcity to yield risk.

The Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP) involves 30 research groups in 12 countries. Katja Frieler heads a team of scientists at the Potsdam Institute for Climate Impact Research (PIK) in Germany who are co-ordinating ISI-MIP.
According to the ISI_MIP team, all research groups involved had agreed to feed the same climate data into their calculating methods for yield volumes, drought periods or vegetation development. They came from five global climate simulations each of which had produced four scenarios of how greenhouse gas emissions were to develop in the 21st century, PIK reported in a press release in late December 2013.

The project is based on earlier comparisons in the individual areas of agriculture, hydrology and ecosystems research. The wider approach now adopted allows for an identification of aspects like regional hotspots, such as the Amazon Basin, the Mediterranean and East Africa, where various climate change impacts coincide and may also influence each other.

As PIK explains, the model comparisons also enable a better understanding of the differences between the computer simulations.
