Breaking news from Physics.org..."In the April 3rd edition of Science a collaborative group of scientists from Switzerland, California and the UK report that medieval climate over Europe was heated by the North Atlantic Oscillation (NAO). This oscillation pattern, defined as the pressure difference between the Icelandic Low and the Azores High, also influences modern-day weather conditions and has contributed to the recent droughts in North Africa and floods in North-Central Europe."
So I guess that makes a big hole in the "It's the Sun" theory of Global Warming.
Nigel from an otherwise intelligent guy that is the most hilarious own goal I have ever seen from an AGW Accolyte. Kind of dumps your credibility a tad So I guess that makes a big hole in the "It's the Sun" theory of Global Warming.
Nigel, the bottom line is this; the planet's been looking after itself for billions of years getting hotter and colder all the time. It's natural, it'll continue to happen and there's sod-all we can do to change it.
You and your ilk only harden my resolve and pity that you've been sucked in. MMCC acolytes are parked firmly in the same pot as 'religionists' - I don't really care what you think, so stop trying to force your views and opinions on me.

Go, Nigel, everything forward anf trust in the lord...
Zut alors, sacre bleu, fartez dans notre general direction, Nige....

"I don't start threads saying I don't believe in MMCC. If we're going along those lines, I'll have to ask you to refrain from creating threads stating you do."

I love that TB the line is that they overspecced the design in essence, rather than oh look Global warming is cobblers so we will be fine with what we have These guys have no shame
Cheers
You guys make me laugh... the Thames Barrier was designed in 1974 on the basis of data and predictions then.Cheers
The Dutch have had sea water defences for hundreds of years and they are currently considered adequate for a few more decades: so were they planning for AGW in the 1500's or did they just put a safety margin in the design?

Rather the ???? meant
Why do you think that...
a) the threads say that I believe in AGW?
b) you have the right to determine which subjects are discussed in threads?
Although you can infer that I believe in AGW if you like I try to keep beliefs out of the discussion and just discuss the substantive issue.

Oh man that is soooo wrong.
Go look it up. First it was global cooling, now its global warming.Here you go:

Go look it up. First it was global cooling, now its global warming.Regardless of who is wrong and who is right, my point was that in the 70s, the "world" was considering global cooling rather than global warming. This apparently is new to Nige.
Having looked at the abstract (but not the paper - don't have access from home), I would say that it does cast doubt on sceptic arguments based on the medieval warm period and little ice age because it suggests that it was a regional rather than global change, invovling a re-distribution of heat, and thus says little or nothing about global climate.
However, like all conclusions based on proxy data (in this case a stalagmite in Scotland and tree ring data from moroccan altac cedar trees) there are always uncertainties and assumptions (bit like the models) and so shouldn't be treated as absolute certainties, more like a plausible possibility with observational evidence that supports it.

Ludo, your comment on the fact that the research indicates the MWP was worldwide and not just European?!?!
No, the sceptics claim that the MWP and LIA were global phenomenon, the article suggests that they were only regional events caused by a merely local redistribution of heat rather than any change in global average temperatures (ISTR that global tree ring data would support that, but also subject to the uncertainties and assumptions I mentioned regarding proxy data).Sorry if I didn't make myself clear.
ETA: of course it doesn't rule out the possibility that both a redistribution of heat ocurred due to long term changes in NAO/ENSO and changes in external forcings (such as solar), however this still means that the sceptic argument if far from concrete (the New Scientist blog are being rather unscientific by saying it scuppers the argument - that is too strong a statement in my opinion).
