Le climat est la distribution statistique des conditions de l’atmosphère terrestre dans une région donnée pendant une période donnée. L’étude du climat est la climatologie. Elle se distingue de la météorologie qui désigne l’étude du temps dans l’atmosphère à court terme et dans des zones ponctuelles. source : wikipedia

tippingpoint
Take part in the new scientific discussion about looming abrupt changes in the Earth system. This new webinar series invites scientists interested in tipping elements and the broader public to attend.
By replacing thousands of equations with just one, ecology modelers can more accurately assess how close fragile environments are to a disastrous “tipping point.”
Clarity on Climate Tipping Points and Feedbacks
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.
