Has global warming stopped?

The maths isn’t complicated. If the planet were going to be six degrees hotter by the century’s end, it should be getting warmer by 0.6 degrees each decade; if two degrees, then by 0.2 degrees every ten years. Fortunately, it isn’t.

Actually, with the exception of 1998 – a ‘blip’ year when temperatures spiked because of a strong ‘El Nino’ effect (the cyclical warming of the southern Pacific that affects weather around the world) – the data on the Met Office’s and CRU’s own websites show that global temperatures have been flat, not for ten, but for the past 15 years.

They go up a bit, then down a bit, but those small rises and falls amount to less than their measuring system’s acknowledged margin of error. They have no statistical significance and reveal no evidence of any trend at all.
