Quite impressive.

Wow. That is impressive.

Strange really, it's only water. Stuff you drink when thirsty - looks completely different in a glass!

280mm of rain in three hours at Montpellier today.  Flash floods, of course, not helped by the tripling in size of Montpellier since the 1950s.  Concrete everywhere, no natural drainage, etc etc.

In the end they (France2 and meteoFrance) are saying 300mm of rain in24 hrs, which is what you would expect in 6 average month for Montpellier.  The end of the month totals for France were 1.4C  higher than average, 4% more sunshine that usual for September and 56% less rainfall than normal.  Except in Montpellier, of course.

31.3C recorded yesterday in Corsica, which is a record.  And the warmth around the Meditteranean helps explain the fifth "evenement Cevenol" which hammered the French south coast over the weekend.  The events happen when very warm, very moist air from the sea meets a cold front in the Cevenol delta.  While none of them individually beat the rainfall records (1000 mm in a few hours in the Gard at the beginning of the last century) each one delivered on average about 300mm in a few hours.  And five in less than a month is unheard of.

23.6C in Gravesend and Kew Gardens reported on the radio 2 news this morning, which is a record for this time of year. And yet another Cevenol event is about to kick off along the French Meditteranean coast.

And here comes (this weekend) another one.  Cevenol event that is.  Just be glad you don't live on the French Mediterranean coast at the moment.

And over in Denver, 21.6C last Sunday.  -11C today ith snowstorms..  Now that's a drop in temperature!

And I am going there at the weekend

Now saying it went down to -16C, a 37C drop in three days!  On the news they showed some footage of a newsman throwing a jug of water into the air and snow falling to the ground as it froze so quickly.
Pack an extra jumper.

But the good news is that the worst should be over by the weekend.

Bon voyage.

I tend to listen more to talk radio when driving, last year a guy came on about the melting ice cap at the poles increasing sea levels, his argument was against that claim, demo of that he said to place several ice cubes in a dish and fill with water so they float, now let them melt completely. The level will only rise by a very small ammount as only the ice above the surface can cause further depth.

I'm not sticking my head in the sand (or seawater), we have replaced all bulbs with energy saving LED's, cavity wall insulation, new boiler, double glazed throughout to both save on energy and carbon footprint.

But i ask as climate change is blammed on human activity, so what about the ice age, volcanic eruptions etcetera, solar flares?

I have no doubt we have not helped, but how much of these changes is being caused by natural events beyond our control?
