Climate Change as Source of Future Wars Draws UN Attention

Imagine India in 2033. It has overtaken China as the most populous nation. Yet with 1.5 billion citizens to feed, it’s been three years since the last monsoon. Without rain, crops die and people starve. This is one of the scenarios Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research, presented today to members of the United Nations Security Council in New York to show the connection between climate change and global security challenges.

Climate Change’s Links to Conflict Draws UN Attention

Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research, presented certain scenarios today to members of the United Nations Security Council in New York to show the connection between climate change and global security challenges. In an interview he said: Either rich nations will find a way to supply needy nations suffering from damaging climate effects “or you will have all kinds of unrest and revolutions, with the export of angry and hungry people to the industrialized countries”.

New map pinpoints cities to avoid as sea levels rise

Mahé Perrette of the Potsdam Institute for Climate Impact Research in Germany has calculated local sea level rises in 2100 for the entire planet. While the global average rise is predicted to be between 30 and 106 centimetres, he says tropical seas will rise 10 or 20 per cent more, while polar seas will see a below-average rise. He offers a warning to tropical countries and he says: "Build defences.". Source: New Scientist, 07.02.2013.
