Apparently Venus has more volcanoes, many of them active, than Earth does, so that ain't going to be much good as a Bezos lifeboat
Earth has 1500 active volcanoes, of which at least 47 are currently "farting" to some extent...both undersea and landbased.
The most dangerous semi active volcano covers most of Yellowstone....the geysers indicate that it is actually active. If it were to blow fully, not alot of the surrounding area would exist.
When Mt St Helens blew in 1980, the eruption knocked the Earth off its axis, this happened again when White Island, Krakatoa and Eyjafjallajökull blew their respective tops in the more recent history.
Now given that the Earth core is molten and has cycles of movement under the tectonic plates that occasionally escapes via the volcanoes, the planet on which we are camped out on is in charge.....not humans.
There have been 5 ice ages....the first recorded as 3 billion years ago (long before the industrial revolution) the last being 2 million years ago (again long before the industrial revolution) and thus long before humans produced engines.
There have been 5 mass extinctions...Ordovician-silurian Extinction: 440 million years ago, Devonian Extinction: 365 million years ago, Permian-triassic Extinction: 250 million years ago, Triassic-jurassic Extinction: 210 million years ago and Cretaceous-tertiary Extinction: 65 Million Years Ago.
Therefore it is safe to say that we humans are not significant enough in the Earth's many issues to cause or indeed succeed in another mass extinction nor are we capable of starting or controlling global warming. The Earth is its very own master of ceremonies in that department and we will become extinct long before the Earth either reheats excessively or freezes into another Ice Age.
(A sixth mass extinction is overdue....and I know that to some people that cannot come soon enough)
