30M TONS OF GREELAND ICE MELTS AN HOUR - RISKING OCEAN CIRCULATION WHICH STABILIZES CLIMATES

30 million tons of Greenland ice melts an hour, so a lot of fresh water is going into the polar oceans. This can reduce and/or stop the sinking of heavier salty water at the poles, which is the ocean pump and drives ocean circulation. If that happens, climates all over the planet will change. That process will destabilize a lot including food production.
