“Our science is solid and it proves unequivocally that the world is warming and that this warming is due to human activities,” World Meteorological Organization Deputy Secretary-General Jerry Lengoasa told reporters in Durban, where almost 200 nations are gathered for U.N. climate talks.
The WMO, part of the United Nations, said the warmest 13 years of average global temperatures have all occurred in the 15 years since 1997. That has contributed to extreme weather conditions that increase the intensity of droughts and heavy precipitation across the world, it said.
“Global temperatures in 2011 are currently the tenth highest on record and are higher than any previous year with a La Nina event, which has a relative cooling influence,” it said.
