‘What we know now is that we are facing the worst case scenario’
Jonathan Leake and Tricia Holly Davis Surging global greenhouse gas emissions mean the world now faces likely temperature rises of up to 5-6C this century, according to the scientist leading the international Climate Congress in Copenhagen this week. Professor Katharine Richardson, who chaired the scientific steering committee for the conference, said it was now almost impossible for the world to achieve the UN target of preventing global temperature rise exceeding 2C. "We can forget about the 2C"," said Richardson in an interview. "We are now facing the situation where we have to avoid a 5-6C rise in temperature." Richardson said her comments were based on sifting through hundreds of science research papers submitted to the congress. Details of the research are being presented to delegates this week and will be used in a report for the UN. Her comments were not the only bad news to emerge on the first day of the International Scientific Congress on Climate Change (IPCC) in Copenhagen. Other researchers warned that sea levels are now rising 50% faster than suggested by the Intergovernmental Panel on Climate Change in its 2007 report. It means the world’s oceans could rise by a metre or more over the next century and that low-lying coastal areas will be at risk of inundation with hundreds of millions of people displaced, especially in developing countries. Some of those attending the Copenhagen meeting have dubbed it “the end of the world conference” because the latest research emerging on climate change is so alarming. …
