And we have seen nothing yet. Once all the ice on the North Pole disappears
is when things will really speed up and another positive feedback kicks in.


And the release of methane from undersea hydrates and CO2 from thawed
tundra.

That has not even started yet really. It takes about as much energy to melt ice as it does to warm up seawater by one degree C. Only when the ice is gone you'll see the warming start.
Put some ice cubes in a glass of your favorite drink and swirl it around from time to time. As long as there is ice at all the temperature stays low. Once the ice is gone the warming up starts.
And also all that ice was reflecting a lot of the solar energy straight back into space when the ice is gone more energy will be captured.
And then we will see methane bubbling or spouting up. Trillions of tons of it.
All positive feedbacks.
John
