Research to show UK flooding is from global warming

I have just read about the fact that, for the first time, computer modelling has been able to detect a "human fingerprint" on the increased rainfall that Britain is seeing. They compare climate simulations run with and without anthropogenic GHG inputs, and the difference that shows up is our "human fingerprint". It has been seen in temperature predictions, but the research that will be published this week will be the first time the human fingerprint is said to have been detected in rainfall predictions. It is essential to note that what is happening now — and increasing trend to heavier rainfall patterns over Britain — is what is claimed to have been predicted by the research.

If this turns out to be substantial research maybe it will stop professional denialists like Andrew Bolt and Tim Blair carrying on like school kids with a fart cushion every time a cold snap ensues.

It's official: the heavier rainfall in Britain is being caused by climate change, a major new scientific study will reveal this week...

More intense rainstorms across parts of the northern hemisphere are being generated by man-made global warming, the study has established for the first time ­ an effect which has long been predicted but never before proved.

The new study, carried out jointly by several national climate research institutes using their supercomputer climate models, including the Hadley Centre of the UK Met Office, does not prove that any one event, including the rain of the past few days in Britain, is climate-change related.

But it certainly supports the idea, by showing that in recent decades rainfall has increased over several areas of the world, including the mid-latitudes of the northern hemisphere, and linking this directly, for the first time, to global warming caused by human emissions of greenhouse gases.

I find this hard to believe. I run a site on global warming ( and the one thing I have learned in running the site is that our climate science is not sophisticated enough to pinpoint that there is a human footprint on a regions' current weather patterns.

How's Australia doing? I heard you were in a terrible drought. Maybe Britain can ship some rainfall down your way. Thanks for commenting over at my blog. I've linked you up. Best,...Neil

Excellent artilce in the Mail on 22 July by John Kettley, basically reminding everyone that the current weather is a rerun of the weather of the 50's and 60's, and the REAL reasons for the rain. I wonder if they ran the model BACKWARDS to prove a human footprint then, with less CO2, etc.
