I would not say "hotter" (it does not heat up) but "goes down less quickly in T ° because it remains at the level of 0 ° ...

For the rest I am mixed: the ice is a colossal thermal buffer but I do not know if your explanation (less ice = more cold) is correct from a weather point of view: if there is less ice it is good that it is less cold (above 0 ° C). I think the albedo effect has much more impact than the thermal buffering of ice. But I understand the idea ...

For BP, it's sad to say: but these cold European winters are going to arrange their business well (like all the other oil tankers or energy sellers) ... attention I did not say that it was premeditated !!

Regarding the liquidation I did not follow you because an oil tanker X or Y is the same ... other name, same methods ...

Indeed, Christophe, I should have said relatively less cold, for the atmosphere.
Statically speaking, saying less ice = more cold is difficult to believe. But we are talking about dynamic systems. Suddenly, the assertion is true at a time t.
It is the ocean itself overheated in the tropics that melts the polar ice cap, not the atmosphere (at least too little to compete with the ocean). The melting of the cap has manifested itself significantly at atmospheric temperatures well below 0 ° C!
What is problematic, and I'm going to caricature, is that the liquid-> solid phase change absorbs and "traps" a cold potential as much as the solid-> liquid phase change absorbs and "traps" a hot potential. This absorbed hot potential initially does not have time to be transferred to the atmosphere since the water molecule (even frozen) has better absorption power in the IR spectrum than air. In this first phase, the local air is not sufficiently heated.
This effect is not often noted because its impact is low compared to ocean currents and radiation (including albedo). I took this example above all to confirm the chain reactions of an out-of-equilibrium system ... And therefore, of the difficulty of evaluating the consequences which are most often counter-intuitive.
Indeed, albedo has a much greater impact and thermohaline current even more.
There is no doubt that the current of the gulf stream is decreasing (-30% I think) and that suddenly its benefits too.
However, it is the main player in this balance for Western Europe and for South America.
Going back to BP.
Indeed, BP could find a bargain there and it is not to soften my anger ...
: Evil:
However, the lack of reaction to the pitch shocked me just as much. I am not for impunity in the face of such dramatic consequences due to risks knowingly taken in the name of the profit of a few and to the detriment of all.
What you say is true and it must be taken into account but does not justify passivity, it is too important. However, I firmly believe that these methods would become less customary, even under another name, if they were rightly controlled and seriously punished.
Make no mistake, I don't have it after BP, I have it after everyone who uses these same methods.

Given the staggering volume of offshore oil platforms (thousands of them off the American coast ...) you don't think that now that the soufflé has fallen, no one thinks about it ... or wants to do it to think, and that the 99% of the population who will fill up with gas will be mad about it until the next catamaran ....?

The only "examination of conscience" which prevails, it is the spring around the underlying abusive policy of the "military oil" and the supply available in terms of alternative propulsion which can push to change “the nature of the demand” among the consumers that we are.

The North American continent is affected in turn by snow in exceptional abundance: https://www.econologie.com/forums/post188061.html#188061

So the role of the Gulf Stream would be a priori limited ... unless it influences, as presumed above, too, on the polar winds.

One can, for example, imagine that it contributes to an anti cyclone preserving the American East coast from polar winds ...

To be realistic, even in a century it will be difficult to say what the real trend is emerging today.
Admittedly there can be brutal ruptures, but we are far from being able to affirm that it is the case and I do not see yet a gigantic metorite heading right on the ground to make everything fart!

On the other hand that the populations continue to be "afraid" in this field - even if it is relatively irrational - is "very good", since it leans in favor of the development of sustainable resources such as solar thermal and all the others. ... And that unfortunately it is needed to get things done.

So I change semantics:
- It's a disaster! We're all screwed! Hurry, let's vote for new renewable laws! Help!!! The situation is desperate !!!

Signed: soaked : Cheesy:

Ha ha ha!

And if not, where is the solar activity currently?

ps: for the global catastrophe type 21 12 2012 in google : Mrgreen: Hey 20 12 2012 it would have been more "logical" ... : Mrgreen: : Mrgreen:

Definitely, this Gulf Stream is too strong, it even cools Australia : Cheesy:

Very slight decline for November

Rooooooooh it's Allègre who was right !!! The world is getting colder! Glagla ...

(Second degree ... though)

It's still at altitude: http://fr.wikipedia.org/wiki/Snowy_Mountains

It also snows (slightly) in July / August in alpine resorts!

I like these threads where we go from one extreme to the other without any foundation based on a significant time scale : Mrgreen: But heating or cooling does not matter: the price of a barrel will not stop increasing (peak oil or not) and renewable energies will nevertheless become competitive.

All this is completely the fault of BP, what a bunch of jerks! It's them I'm sure! :P :P :P :P :P
