In a recent review of more than 180 peer-reviewed articles — which I conducted with fellow researcher Richard Parncutt — we found that a scientific consensus has formed around the so-called 1,000-ton rule.
The 1,000-ton rule states that a person is killed every time humanity burns 1,000 tons of fossil carbon. Shockingly, we found that a 2 C temperature rise equates to a billion prematurely dead people over the next century, killed as a result of a wide range of global warming related climate breakdowns.
These findings were derived from a review of the climate literature that attempted to quantify future human deaths from a long list of mechanisms.
