Scorching Global Temps Astound Climate Scientists
Abrupt Climate Change
Without the large-scale sinking of salty water in the North Atlantic the influx of warm water from the tropics to replace it would not occur, effectively switching off the thermohaline circulation. Past changes in have occurred during periods of relatively rapid climate change, such as transitions in and out of glaciations. Similarly, the rapid warming we are currently experiencing could trigger an abrupt shutdown and subsequent regional cooling.
