GENEVA (Reuters) - Global temperatures are on course for a 3-5 degrees Celsius (5.4-9.0 degrees Fahrenheit) rise this century, far overshooting a global target of limiting the increase to 2C (3.6F) or less, the U.N. World Meteorological Organisation said on Thursday.
“Greenhouse gas concentrations are once again at record levels and if the current trend continues we may see temperature increases 3-5 degrees C by the end of the century," Secretary-General Petteri Taalas said in the WMO's annual statement on the state of the climate.
