THE WEATHER:

If the jet stream remains seasonally to the south as it has been this 'spring' (2013), all we need is for the gulf stream to drift away from our west coast and we will become seriously cold, year round.

Those who thought that 'global warming' meant they could start growing grapes in England would be well advised to think again.

The following statistics are derived from my own readings of temperature and rainfall in my garden in Yorkshire.
Temperatures are MINIMUM NIGHT TEMPERATURE.

Apart from the possibility of fewer hot nights than there used to be, and the obvious high total rainfall in 2012, there is no clear trend in any of the above except in annual rainfall standard deviation. What this means is that the higher the number, the greater is the irregularity of rainfall through the year. This might have meant an increasing number of very wet days and very dry days, but the number of days with NO rain (the lowest I record is 0.05ins) is not increasing therefore it appears that the rest of the days which used to have fairly regular rain are becoming divided into very high and very low.
