In an interview with Saarbruecker Zeitung newspaper Schellnhuber, who heads the Potsdam Institute for Research on Global Warming Effects and acts as an adviser to German Chancellor Angela Merkel on climate-change issues, said that "the threats posed by climate change are worse than those imagined by most governments."
Schellnhuber points out that the Arctic ice is melting faster than previously expected and says that "the entire climate pattern at the North Poll has been disrupted to the extent of causing irreversible change."
Schellnhuber says that to be able to stop global warming the industrial countries need to decrease their emissions by 80-90% and that by 2020 "this process has to be well underway".
