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 ...
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.
