La presse générale n’est en effet pas une source fiable, alors lisez des journaux scientifiques comme ceux de l’American Meteorological Society (AMETSOC) qui sont parmi les plus réputés au monde sur le sujet. Leur Climate Change Statement dit :

Warming of the climate system now is unequivocal, according to many different kinds of evidence.

The most important of these over the long term is CO2, whose concentration in the atmosphere is rising principally as a result of fossil-fuel combustion and deforestation.

A un certain moment, le scepticisme scientifique devient de la mauvaise foi…
