It should be apparent from both the temperature and rainfall datasets that British climate is changing much less than we are led to believe.
The Met Office has now published its data for 2018. We can expect plenty of claims about last year being the 7th warmest in the UK since records began (in 1910). Or that all of the ten warmest years have occurred this century. The real significance of these latest numbers, however, is that they continue to confirm that UK temperatures stopped rising more than a decade ago, after a step up during the 1990s.
As the 10-year averages below indicate, UK temperatures have been stable for some time, and arguably are now beginning to drop back:
The current 10-year average of 9.18C is back to where it was for 1996 to 2005. Significantly, it is also close to the 30-year average of 9.15C.
Of course, 10 years is far too short a period to be meaningful in terms of long term trends and projections. But exactly the same argument applies to that short burst of warming, which effectively began in 1989 and ended in 2006.
What we can say with confidence, however, is that that period of warming has now ended for the time being.
