Seasonal Shift

Okay, the weather round here has been bloody weird recently. As some people will already know, a lot of the country is suffering from flooding at the moment due to sudden torrential downpours.

Here in London we've had it fairly easy. It's been a little damp, but still mostly sunny. Sort of. In fact what we're actually getting is a generally sunny day (albeit a bit cold) but interrupted by 10 minute bursts of monsoon.
Right now as I look out the window, most of the sky is grey with some patches of sun breaking through. And hail is falling.

This phenomenon is what I have decided to call Seasonal Shift.
Basically, my theory puts it down to global warming and the change in the winds which normally bring the different seasons. As the earth heats up, the winds and tidal currents are changing direction and strength, bringing unfamiliar weather to new places. It is also pushing our seasons out of alignment, giving us later summers and winters.

Let's look at when I was a child. We got snow in December almost every year (although never enough on Christmas day). It fell thick and lay for weeks.
These days December is mild and wet, and the snow isn't arriving until February and March and isn't last long because the Earth is closer to the sun (on it's normal orbital trajectory).
Our summer has been pushed into August/September, meaning we're getting "April Showers" well into June.

And that's only in about 20 years. I don't know what will happen if Summer and Winter reverse entirely, but let's hope it slows down before they do.
