sorcellerie supercherie.. il me semble que ça fait un bout de temps que j’utilise ces qualificatifs.. et même plus ! 

For a climatic heating of + 1°C at 15°C
ground radiation increases by 1,4%
air moisture increases up to 6%
It’s PHYSICS, not SORCERY

The planet is covered by water at 75%, 70% with clouds and cools mainly by areas unmasked by clouds, ie 30%

An increase by 6% of clouds areas leads to a reduction of cooling areas by 16 % and thus the cooling as much !

it is +10 times more than the increase of radiation of the ground !

It would thus be enough to an increase by 0,5% the clouds area to block a heating of 1°C on the ground.

It is thus not necessary to call upon supernatural (CO2 greenhouse effect) to justify climate change and simply to save energy as much as possible.
