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. REUTERS/Denis Balibouse “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.
