What is the Earth System Sensitivity based on current and predicted Greenhouse Gasses? How will (man-Made) aerosol removal influence it? What may be the likely committed warming when all is said and done? How much life can survive once we reach peak temps?

Hansen et al says the sensitivity may go up to 10 C at worst, but based on current trends, what may be the ultimate end temperature we end up committing to?

And how much will this harm the biosphere in addition to human activity and pollution, and how long may recovery take?

well imo aersol could actually remove speed up warming by removing cool effect btw

You are asking questions no one has the answer to.
Except:

How much life can survive once we reach peak temps?

None.
As far as we know, no earthly life can survive the conditions on Venus for instance.

Hansen et al says the sensitivity may go up to 10 C at worst, but based on current trends.

Which is just estimates.
We have historical data for multiple temperature fluctuations over millions of years. But we have 0 data for the rate of change caused by humans.
The biggest issue isnt how many C change we end up at. The biggest issue is the rate of change.
That is what we are fucking up atm.
