Are the cold spells caused by climate change? Are they becoming more frequent?

I don't know in answer to both questions.

But, this Guardian article on the fluctuating jet stream puts across some interesting ideas as to why we have experienced a number of cold winter periods over the last three years.

What I do know is that high pressure centred to the north of Britain in winter results in excellent winter climbing conditions, particularly in the Lakes (links to Paddy Cave's blog) and north Wales (links to James McHaffie's blog report).

Thanks to Dougie, Craig, Lucy and the jet stream for the climbing and banter.

Fingers crossed for warm weather and dry rock. Definitely time for cragging!
