Climate change is happening much faster than the world's best scientists predicted and will wreak havoc unless action is taken on a global scale, a new report warns. 'Extreme weather events' such as the hot summer of 2003, which caused an extra 35,000 deaths across southern Europe from heat stress and poor air quality, will happen more frequently. Britain and the North Sea area will be hit more often by violent cyclones and the predicted rise in sea level will double to more than a metre, putting vast coastal areas at risk from flooding. The bleak report from WWF -- formerly the World Wildlife Fund -- also predicts crops failures and the collapse of ecosystems on both land and sea. And it calls on the EU to set an example to the rest of the world by agreeing a package of challenging targets for cutting greenhouse gas emissions to tackle the consequences of climate change and to keep any increase in global temperatures below 2C. The agency says that the 2007 report from the Intergovernmental Panel on Climate Change (IPCC) ... is now out of date. WWF's report, Climate Change: Faster, stronger, sooner, has updated all the scientific data and concluded that global warming is accelerating far beyond the IPCC's forecasts. As an example it says the first 'tipping point' may have already been reached in the Arctic, where sea ice is disappearing up to 30 years ahead of IPCC predictions and may be gone completely within five years - something that hasn't occurred for a million years. It could result in rapid and abrupt climate change rather than the gradual changes forecast by the IPCC.
