if these tipping points are crossed in the Arctic, then they can cascade through domino effects and hit the Amazon, and then Rainforest and Hit Antarctica
for - example - cascading tipping points via AMOC
example - cascading tipping points via AMOC - As Arctic system melts faster, it releases more freshwater into the North Atlantic - This is happening on the southern tip of Greenland, for example and the lower density of water slows down the AMOC current - Warm saline water flows from the Southern Ocean up into the North Atlantic - When it reaches the southern tip of Greenland, the heat is radiated into the atmosphere and heats up Europe - When the freshwater meltwater from Greenland mixes with this AMOC current, the AMOC water is less heavy and sinks slower - This pushes monsoons further south, which can explain why there are more droughts and fires in the Amazon rainforest - The slowdown of the AMOC leaves more saline water stuck in Antarctica, potentially contributing to the faster melting of Antarctica glaciers
