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

That article is wrong on a number of facts.

For example, it explicitly mentions 10 degrees C of warming over the next century.

A 10 degrees C scenario is not something that any respectable scientist believes is going to happen.

The IPCC, which is the official authority on climate change, believes that there will be a 2-3 degrees C increase in temperature over the next century.

Thats the facts. Please listen to the scientists. Every single doomsday prediction that this guy is making, can be traced back to this fundamental problem that he is talking about scenarios that the experts and the scientists do NOT believe has even a remote chance of happening.

Such short-term warming due methane clathrates is certainly possible. A study based on a coupled climate–carbon cycle model (GCM) assessed a 1000-fold (from <1 to 1000 ppmv) methane increase - within a single pulse, from methane hydrates (based on carbon amount estimates for the PETM, with ~2000 GtC), and concluded it would increase atmospheric temperatures by >6 °C within 80 years. https://en.wikipedia.org/wiki/Clathrate_gun_hypothesis#Model...
