Climate alarmists have finally admitted that they've got it wrong on global warming.

This is the inescapable conclusion of a landmark paper, published in Nature Geoscience, which finally admits that the computer models have overstated the impact of carbon dioxide on climate and that the planet is warming more slowly than predicted.

The paper – titled Emission budgets and pathways consistent with limiting warming to 1.5 °C – concedes that it is now almost impossible that the doomsday predictions made in the last IPCC Assessment Report of 1.5 degrees C warming above pre-industrial levels by 2022 will come true.

In order for that to happen, temperatures would have to rise by a massive 0.5 degrees C in five years.

Since global mean temperatures rarely rise by even as much as 0.25 degrees C in a decade, that would mean the planet would have to do 20 years' worth of extreme warming in the space of the next five years.
