This was 6 years ago. Just to remind the climate change deniers. The 2013 report states Global warming is “unequivocal”, according to the fifth IPCC report which, after six years in preparation, delivers a detailed picture of the science behind climate change.
In the strongest language yet deployed in the fight against increasing temperatures, the report concluded that the 30 years until 2012 were probably the warmest in 1,400 years for the northern hemisphere, driven by “unprecedented” levels of greenhouse gases – these are now at levels not seen for 80,000 years.
But what would real scientists know??
