quote:Sun, ice and snow
Polar regions significantly influence the global climate : Ice surfaces have a high ability to reflect solar radiation, the albedo. Surfaces covered by ice are warming significantly less than uncovered surfaces. If global warming decreases the ice cover, the albedo will sink and thus enhance further warming. Possible future changes in Arctic sea-ice cover and thickness, and corresponding changes in the ice-snow-albedo-feedback, represent one of the major uncertainties in the prediction of future temperature change.
Global consequences of Arctic climate processes
Results of the modelling demonstrate that a change in the polar energy sink region can exert a strong influence on the North Atlantic Oscillation (NAO). The NAO is explained by fluctuations between the Iceland low pressure system in the northern, and the Azores high pressure area in the southern North Atlantic. A positive and a negative phase is distinguished. A stronger wets-east-current in the North Atlantic accompanies the fluctuations in air pressure in the positive phase. Thus more warm and humid air reaches northern and middle Europe.
That may well be true, DL, but do you see anything to suggest that Mas's lack of snow ISN'T a result of global warming? Yeah. Take that.
Also, if you DO see anything to suggest that Mas's lack of snow ISN'T a result of global warming, please do not tell me. I've constructed a very flimsy house, and you don't want me to be homeless.

Yeah - all that stuff I said before
WS - it may very well support what you see happening around you, although it is quite vague.
It still has nothing whatsoever to do with a a sudden change from "the most snowiest" to the "most snowless" winter from one year to the next, and such a change is not data that can be used in reference to global warming.
FWIW, we are also experiencing a very warm and snow-free winter here in New England so far (though that seems about to change starting this week...)
A couple of years ago, we had a particularly cold and nasty winter. Looking back through the history - while we may not have specific data - we do have records in the journals going back to the first colonists, of harsh winters and mild winters.

I am not debating the very sudden change of winters from one to the next - I am debating that the extremes that they are going to have not been recorded before and the data suggests that the reason is the Warming of the Artic Ice (at least where I am) - and that is attributed to Global Warming. Thus, it would suggest through the Associative Property that the season extremes here are related to Global Warming.

This has been said several times here, but I still haven't seen anything to support it.
A decade worth of preogressive change warrants more attention, but even that is an awful small time frame. But I haven't seen the evidence of that either...
If I missed that info in your links, my apologies. All I found was general information about the effect of arctic wind on European climate.
For us British units people, assuming we start at 0 degrees Celsius and go up .5 degrees Celsius, we go up .9 degrees Fahrenheit. Now you may say, the earth is so massive! One degree is such a big thing when you get to be on a scale so big! But I say the population has increased 3.55 billion (Google work here) and the number of cars has increased from a rather ambiguous digit of 7 to an equally ambiguous digit of 45. (First link on "Number of cars in 1950".)
So to answer the original question, do I care about Global Warming? :P No, not really. There's more pressing matters.

life: nothing appropriate.
At more or less the same time that EXXON ~cough spit~ announces the largest yearly profits ever in the history of mankind no really. In a smoke free Paris boardroom The IPCC have announced their findings on climate change, which I hope will really make the dumb selfish politicians sit up and take note. Aunty Beeb also has a good page on the subject here
Sorry once again I have to post and run and not get involved in the cut and thrust of the discussion, but such is my fate at the moment =(
There are reports of making this report much more strongly worded than any other to reflect the urgency of the matter. I can only hope that the nicotine withdrawal pangs have started to kick in at the Paris venue and the journalists are getting irate and uppity enough to scream. There has been a ban on smoking in public places in France in case you are wondering what I am going on about
Shine on
I care about it. I think the preposterous and almost religious assertion that humans are to blame for it - further; that we can avoid it by living more frugally - is dangerous and misguided. Instead of making preparations for the inevitable events to come, we're ignoring the opportunity to lessen the catastrophe.
I'd be astounded if our 'green' attitude makes a difference to Earth's climate while Mars keeps getting hotter under remarkably similar circumstances. Perhaps we could advise the Martians on our master plan for averting disaster.
Oh, hang on... there aren't any power stations, 4x4 school-runners, factories, or cattle farms on Mars are there?! I wonder what utterly different and obviously unrelated influences are causing Martian global warming then..?
