"Hope"

Is there hope for a future,...

Well as I've read. if they shut down the entire planetary industrial network. Every power plant every mine every factory every carbon producing technology. If this were done it would take near 300 years for the climate to 'begin',...just begin to stabilize.

This because the damage we've already done.

The pollutants centuries worth still in the atmosphere with take that long to begin to seriously dissipate. After that another 2 to 400 years for the Earth to return to a pristine pre-industrial level. So 500 to 700 years to heal the Earth if we shut the whole thing down,...which we will never do.

This is why for me at least it doesn't matter what we do,...we're headed certainly headed for a pre-mature extinction. Many other species will be taken along with us,...by us. Of course it's not the end of the world or life on this world.
When we're finally gone in anywhere from a few centuries to a few thousand years. The earth will heal.
That, and new species will fill the niches left by the great extinction we caused.

So yes there is Hope.
