Humanity is causing a mass extinction, of the type that will take the planet’s ecosystems hundreds of thousands of years (or much longer?) to recover some kind of equilibrium after. For example, most of our coral reefs will die and never return in the same form. The question now is how complete that destruction will be. I agree it’s a bit silly to lay that entirely at the feet of airplane travel, but even if we could magically halt all other carbon emissions tomorrow, we would still probably need to deal with carbon emissions airplane travel in the near future if we want to avoid catastrophe. As for the rest, I guess the question is whether you consider “trouble for life on earth” to necessarily mean complete annihilation of all life vs. just killing off most of the species and fundamentally altering most of the ecosystems.
