The spike in global temperatures is bigger than any seen in the past 11,300, scientists said in research published Friday.
Temperatures have not risen as fast as they are now in the 11,300 years that the US researchers studied and climate models showed that by the end of this century, temperatures would be warmer than anytime since the last ice age, they said in the journal Science.
Their data - compiled by studying such things as ice cores, fossils and ocean sentiment - looked back over a much longer era than previous research, which went back 1,500 years.//DPA
