LONDON, Feb. 19 (UPI) -- Studies of Greenland and Antarctica indicate it may be too late to do anything to prevent melting ice sheets and rising sea levels due to global warming.
The prediction is contained in the final draft of a report by the U.N. Intergovernmental Panel on Climate Change, which warns sea levels could rise anywhere from 6 feet to 13 feet, The Guardian reported Monday.
The U.N. panel concludes there is a 50 percent chance that widespread ice sheet loss "may no longer be avoided" because of greenhouse gases in the atmosphere.
The report comes in the wake of information released by Christian Aid that only 16 of Britain's top 100 listed companies are meeting the government's reporting guidelines on greenhouse gas emissions.
Christian Aid said emissions running into hundreds of millions of tons of carbon monoxide have not been disclosed by Britain's biggest businesses.
