6.5 deg C and pools of water on top of ice pack indicate that a period of above freezing temperatures of more than several days has been experienced. The average summer temperature is -1.5. Don't you think GW is right to be concerned?

I predict this winter will be in December, January and February.

And another one now in Greece http://news.bbc.co.uk/1/hi/world/europe/7442705.stm Also another aftershock of mag 5 in China.

Oh no not that debate again

This is good - I presume he's right.

No worm holes - I'm disappointed now. :o If this does (which I don't believe it will) cause the end of the world I would find it very satisfying that humanity destroyed itself for the quest for knowledge as opposed the more likely reason - greed.

http://www.realufos.net/2008/04/lhc-large-...er-is-cern.html I'm scared but look forward to the switch on. It could turn out to be not quite powerful enough though :o

Amazing plume stretching right across the continent and in to the Atlantic.

Any predictions of what VE type the eruptions have and may be. This is proving very interesting (not that I take delight in suffering). I have spent some time in Chile and was amazed by the amount of smoking volcanoes at regular intervals along the whole length of the Andes. I've not visited this particular volcano but i have spent sometime exploring Llaima which had erupted the year before and left an incredible lunar landscape of small razor sharp pebbles over a very large area - made camping very precarious! If this does turn out to be a major eruption the climate impact could be great with one half of the globe cooling and the other warming - the chance for unpredictable weather is great i would guess.

The eruption in Chile seems to have intensified. http://news.bbc.co.uk/1/hi/world/americas/7386050.stm Viking, with your knowledge of these things how does the latest eruption scale in terms of effect on climate.

In response to some of the posts here that 'everything is ok' or the earth isn't warming etc. I would like to draw a comparison with the current economic situation we are in. This time last year everyone expected and planned as though it was business as usual, house prices would continue to rise and we would all become millionaires. Everyone (or at least the majority) comforted themselves that economy has never collapse before and if it did it would sort itself out. Well, as we are discovering when something is not right with a system it corrects itself rapidly and sometimes dramatically. Climate and its response to human induced changes can and probably will at some point make equally dramatic (and possibly catastrophic) abrupt corrections. Can we, should we take such risks?

And here is the BBC report on the findings http://newsvote.bbc.co.uk/1/hi/sci/tech/7303385.stm

OON on your next pasty trip drop in at Cockermouth Market Place - as a landscape architect you may appreciate what we are doing to the place! (I'm involved, unfortunatly cant claim to be the designer but i can say i've stood the ground for quality and a contemporary feel as my role as design guru on the steering committee). Its not finsihed yet but you may like looking at holes as much as i do. :o

957.3 here.

In its simplest terms thats the daisy world hypothesis - this a java experiment showing how it works http://gingerbooth.com/courseware/daisy.html

Very interesting, wish he'd had it proof read first to find the odd missing word. But I think he is right - over consumption by a greedy self-obsessed righteous species will do irrevocable harm to all it touches. As he points out we are in terms of development still in our childhood (maybe young adults, but still teenagers) period and as such arrogant and bereft of any wisdom.

Yep but only 30 years from now.

No not that famous, only famous to architects and australians - Glenn Murcutt Around here yes, but in the wider world no.

Point taken Noggin, perhaps I should have put the term deniers in quotation marks. It was not a criticism directed at you personally more one intended to group the holders of the popular view that 'if we are not warming then we can continue down the same path without a care in the world' camp of people. I think you will agree we live in a self-obsessed selfish world where there can only be short term benefits! Whether warming or not, natural cycle or human induced we must keep an open mind and do our utmost to do the right thing.

To use a famous architects quote we should strive to always "touch this earth lightly". What is wrong with aiming to reduce our carbon footprint if it means a more reliable, politically stable and potentially endless source of energy be produced. We should, and must, be concerned that we as a species are having some effect on the planet as a whole and to be more respectful of our own home is essential. The AGW deniers only lead to a continuation of the buy now, pay later, attitude - it will come crashing down, the world is a finite resource.

Also worth reading this too - NOTE the last couple of paragraphs!!!! http://wattsupwiththat.wordpress.com/2008/...past-12-months/

Frightening but perversely fascinating stuff.

To add to that catastrophic view we need also to factor in the effects of the changes in weight on the continental shelf. If this is an active volcanic area or one prone to seismic movement then these activities will be pushed in to possible further action. This is an area of research little explored but one studied in relation to large dam projects as the building of a dam to hold back vast quantities of water do and have in the past caused local seismic activity so any dam must be designed to withstand it or not build it at all. If a volcanic activity is induced then any reduction in albedo could cause very rapid thaw.

Its about 20 years, although some souces say between 6 months and 20 years. But it wil depend on how well the natural sinks are working - if full then 20 years could become much longer. Sorry made a typo its 200 not 20 - soucre: IPCC Scientific Assessment (1990)

Not to with Ozone but the final paragraph or 2 of this article posted elsewhere may be relavent. http://www.dailytech.com/Solar+Activity+Di...rticle10630.htm
