From a deep environmental perspective, the earth will recover, when we have substantially wiped ourselves out.
"Recover" ??? That's a very anthropocentric way of looking at it.
The Earth will continue to exist, in some form or other, whether we're here or not. We're not substantially changing the Earth, except for the 10-mile thick skin that we need to exist.
What I was attempting to say (as simply as possible) is that the biosphere as a whole is dynamically stable. It reacts to perturbations via adaptation of organisms and ultimately recovers objective measures of innate ecosystem health like diversity, biomass, abundance and trophic flow. It settles on a new equilibrium that is functionally the same but at a species level may be different.
This is what the fossil record shows to have happened after previous mass extinctions. From time to time the planetary conditions regulate the biosphere (e.g. snowball earth). Most of the time the biosphere (including humans) regulates planetary conditions - e.g. climate change.
A planet-scale example of recovery is the carboniferous period (after the Late Devonian Extinction event). A micro-scale example is Chernobyl.
It would take a solar-system scale perturbation to stop the biosphere from recovering.
The words "ultimately recovers" are important here. Consider this assessment of how long CO2 lasts in the atmosphere:
The lifetime in the air of CO2, the most significant man-made greenhouse gas, is probably the most difficult to determine, because there are several processes that remove carbon dioxide from the atmosphere. Between 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years. The rest is removed by slower processes that take up to several hundreds of thousands of years, including chemical weathering and rock formation. This means that once in the atmosphere, carbon dioxide can continue to affect climate for thousands of years.
So, although it's very important to strive to reduce CO2 emissions urgently, it may already be too late, bearing in mind that CO2 "can continue to affect climate for thousands of years".
