The problem is that video was 2007. It is worse now. It is improbable that people will reduce emissions even close to 90% of 1998 level, unless they are hit by due geologic and financial events which start a population crash in time. Otherwise the only way to save the biosphere then will be to cause a super-volcanic eruption.
That would be horrible for portions of the biosphere if we saw a huge volcanic eruption.
Yes, but not as bad as another thermal max event and one that is a worse ELE than ever seen.
All Toba did was cause a 10*F temperature drop for 10 years and it killed off 99.9% of humans,
a bottleneck, but not an ELE. Because there is substantially more sequestered carbon than ever before,
a thermal max could even go to full turnover with eventual "Venus Effect".
The end of a positive feedback loop caused by human overpopulation and extreme pollution.
Nothing like it except the cyanobacteria that changed the world to animal friendly!
Its a hell of a thing to kill a world.
