We are so screwed.

Ongoing debate involves asteroid or not and Siberian Traps alone but counter argument has Traps resulting from being antipodal of asteroid, etc.

super vid and the documentary would be great aswell.

One thing really bothers me. This increase in temperature and greenhouse gases have played their part in almost all extinction events. Even in this case, 5 deg increase releases methane hydrates from bottom. But after the increase of 10 deg, why is it that the carbonate rocks don't start releasing CO2 and the greenhouse effect becomes runaway like our neighbour VENUS. Afterall that can happen here even though we are further away than VENUS.

You'd have to increase the temperature by approximately 500 C to decompose carbonate rocks.
