Alaska’s thawing soils are now pouring carbon dioxide into the air

I believe (but cannot prove, obviously) that we're way past the tipping point. Meaning simply reducing anthropocentric emissions, even down to zero, will not meaningfully impact atomspheric CO2, methane.

For civilization to survive, we must adapt, mitigate, or both.

The scientific consensus is that sea levels will rise by 1-2 meters over the course of 200 years.

Thats the science. And it doesn't sound like extinction to me.

Sea levels aren't the only source of trouble. Changing rainfall amounts for example would impact our ability to grow crops.

Yes, extinction seems unlikely. But the planet's ability to support the current population could easily be a casualty.

I think the concern is that the models in use don't take these additional feedback loops into consideration because they're difficult to predict.
