Phys.org  November 4, 2024 The Atlantic meridional overturning circulation (AMOC) and the Amazon forest are viewed as connected tipping elements in a warming climate system. If global warming exceeds a critical threshold, the AMOC may slow down substantially, changing atmospheric circulation and leading to Amazonia becoming drier in the north and wetter in the south. An international team of researchers (Brazil, Morocco, Germany, Switzerland, the Netherlands, UK, France, China, USA – Keller Science Action Center) used pollen and microcharcoal data from a marine sediment core to assess changes in Amazon vegetation from 25,000 to 12,500 years ago and modeled vegetation […]
