Is it possible to have such evidence in time to avert
climate change?

This seems as good as anything:

As plants consume CO2 for photosynthesis, deforestation and land
clearance (particularly if it then turns into a desert) worry me more
than burning fossil fuels. With enough plant life, the Carbon in CO2
is naturally recycled.

As the Earth has maintained reasonably stable temperatures (with
relatively minor variations) for billions of years, it must have
pretty good natural control and feedback mechanisms. Otherwise life on
it would have already died out.
