Also; The public debate about the alleged warming pause was misguided from the outset, because far too much was read into a cherry-picked short-term trend. Now this debate has become completely baseless, because the trend of the last 15 or 16 years is nothing unusual even despite the record El Niño year at the beginning of the period. It is still a quarter less than the warming trend since 1980, which is 0.16 °C per decade. But thats not surprising when one starts with an extreme El Niño and ends with persistent La Niña conditions, and is also running through a particularly deep and prolonged solar minimum in the second half. As we often said, all this is within the usual variability around the long-term global warming trend and no cause for excited over-interpretation.Global temperatures are almost half a degree Celsius above the long-term average so far in 2013, putting this year on course to be among the 10 hottest since records began, the world's leading meteorological agency says.
In a provisional statement on the global climate in 2013, the World Meteorological Organisation says the first nine months of this year tied with 2003 as the seventh hottest such period on record.
The statement was released in Warsaw on Wednesday where countries are meeting for the latest round of negotiations on a new treaty to tackle global warming.
