No coincidence...
... that since they started incorporating "climate change" into the model that their forecasting accuracy has gone to shit.
Better off getting your forecast from organisations which use NOAA data as in my experience it is considerably more accurate over short, medium and long-term forecasts. Whether they have "climate change" incorporated into their models I don't know but the Met Office has been worse than useless for the last decade.
NB - I think its pretty bloody obvious that more than doubling the human population over the last 50 years has an effect on the environment. However I'm no longer convinced that the IPCC or any of the other agencies dependent on public funding are doing anything other than scaremongering to keep their gravy trains running smoothly.
