We Are Unbelievably Screwed

It looks like a collopse of the Atlantic Meridional Overturning Circulation (AMOC) is increasingly likely.

This will disrupt weather over the world, but particularly in Europe, where would could see temperatures drop by 10°C (18°F).

Note that Paris, France is 3 degrees latitude further north than Toronto, Canada, so this is a big deal.

Time for a climate update. Tipping points are approaching. To present this information this systematically, consider the following:

•  Bad things are already happening, and they’ll continue.
•  Over not much time, the bad things will also get worse.
•  Then tipping points will be reached, after which the worst is baked in.
•  Some years after that, the worst arrives in full.

This process is true in a great many areas: sea level rise, for example, and coastal destruction.

The seas are already rising, due partly to ocean expansion (warm water takes up more space than cold water), but due mainly to melting ice in Greenland and Antarctica. Once the tipping point for glacial melt has been reached, all ice will be guaranteed gone at some future time, and a full sea level rise disaster is bound to occur.

What will that look like? Greenland ice melt will cause 24 feet of sea level rise; Antarctica ice melt, 230 feet. The world’s coastal cities, where 15% of world population lives, will erode with the shores and be drowned. In the U.S., 45% of GDP will be lost. 

The tipping point for the collapse of AMOC is currently predicted at 10-30 years.

We need to do something now,  and we are currently ruled by people who are literally pro anthropogenic climate change.

Game over, dudes!
