To quote the BBC website, verbatim:

Monthly forecasting

The weather beyond about a week ahead stretches even the most experienced weather

forecaster. Complex numerical weather forecast models from the Met Office and the

European Centre for Medium Range Weather Forecasting (ECMWF) are run many times for

the month (and season) ahead to build up a picture of the likelihood of different weather

types affecting the UK.

So, when your 'government' or 'industry', either national or local tells you that they are going to mitigate, you may reply 'mitigate what, exactly?' If there are man-created instabilities we don't know exactly what they will bring, a good reason to rachet back all our economic nonsense. However, if we manage to break the Atlantic conveyor and our winters start getting really cold (this year is nothing much, think Moscow), this may solve some of our problems for us.
