Intelligence Artificielle

Attribuer un "label vert" européen au gaz naturel et au nucléaire, pour aider à flécher les investissements : cette perspective fait tiquer bien des défenseurs du climat et de l'environnement. Alors quelle place pour ces énergies sur le chemin d'un monde sans carbone?

The Atlantic Meridional Overturning Circulation (AMOC), a major ocean current system transporting warm surface waters toward the northern Atlantic, has been suggested to exhibit two distinct modes of operation. A collapse from the currently attained strong to the weak mode would have severe impacts on the global climate system and further multi-stable Earth system components. Observations and recently suggested fingerprints of AMOC variability indicate a gradual weakening during the last decades, but estimates of the critical transition point remain uncertain.
