I'll disagree here. The Tibetan plateau did not erupt. The Himalayas, including the Tibetan plateau are the result of uplft from the collision of the Indian and Eurasian plates. Certainly there is volcanism associated with this along the northern margin where there are a few andesitic volcanoes. However only a tiny part of the high ground in the region is volcanoes. Most of it is just rocks that have been pushed up as the Eurasian plate has ridden over the Indian plate.

Yes "Eruption" was a poor choice of words.
"Up-oozing" is probably better.
I watched this on
some respectable science type-program which wasn't actually about vulcanism, but the Chinese annexation of Tibet.
It seems they did loads more Geophysical surveys than any-one previously and found HUGE areas that had been formed by 'up-oozing' originally thought to have been the products of the collision with India.
I wish I could remember the show, cuz it was very interesting.
At any rate.
All this CO2 we and our volcanoes are busy pumping into the air isn't just sittting there, it's being absorbed and re-used and really hasn't made any appreciable impact on the actual percentage of CO2 in our atmosphere (0.04%?).
There was far more, back when you had to fight a T-Rex to get to the office and
Life was positively everywhere.
