Oh it'll sustain life, even human life, in 100 years. It'll just be life full of escalating humanitarian crises.
It's 500-1000 years from now when shit would get civilization-ending bad, even if emissions 100% stop by 2100. A mass extinction that could take humanity with it.
But life would still exist. Just not humans or 90% of other species. Earth would "reboot" under a higher-CO2 status quo and life would evolve to fill empty niches in that status quo. Species that can handle consistently warmer temperatures, more acidic oceans, more extreme weather, and climatic zones moving to different parts of the planet.
A lot will depend on what we can achieve during this time of change and impending doom, in balancing what is already sacrificed but still trying to hang on to what is left.
