The big problem we have is there’s certain carbon stores that are likely to initiate a runaway greenhouse effect if we reach the tipping point that starts to release the like the Arctic tundra.

The honest assessment is that we’re in the early stages of another mass extinction event, the discussion is whether it’ll be a Permian-end level mass extinction (95% of extant species) or Devonian-end level extinction (75% of extant species).
