Record Rainfall in the UK
BBC News - It's still real and it's still a problem
The evidence of change is indeed there.
The glaciers of the Alps and the Himalayas are retreating. Weather patterns around the world are becoming more erratic and more extreme.
The most intensive rainfall ever experienced in one location over a 24-hour period in England fell on Cumbria last November, and caused the tragic consequences of the severe flooding that we saw in Cockermouth, Keswick and Workington.
We cannot say for certain that these things - or indeed the intense heat recently experienced in Australia, or the droughts in Kenya - were caused by climate change.
But we can see with our own eyes that climatic, weather and temperature trends are changing, and we know that these hitherto exceptional events are likely to become more frequent over coming years.
So what does the record rainfall series in the UK look like?

Is that a trend or a random walk? Of course with records only higher ones are recorded as time goes on and much statistical analysis has been done on such things. Stuff like using Markov Chains to estimate the probability of rare events, I wouldn't dare try and expand on the theory and show up my ignorance, but others can.
