Summer of 2023. We can and must stop escalating climatechange destruction by starting Stratospheric aerosol injection now

I encountered this blog post on mastodon and I’m wondering what would people’s thoughts be on this. It has some strong arguments in favor of SAI.

    The main problems I have with it is::

    Once you begin (without actually reducing co2 emissions), you can never stop.

    You will have to increase the rate of SAI every decade, in perpetuity.

    If, for any reason (war, political instability, economic burden etc), the SAI stops the rapid change in temperatures will be devastating to ecosystems on a level that would make our current rate of change look like paradise.

    From what I remember of the effect the Mt Pinatubo eruption in 1991 had of global warming the effects disappear within 5 years. If humans want to reverse warming we will have to push well past the “safe max co2” of 350ppm.

    My little End of SAI Nightmare Senario.

    Its 2100 After 50 years of SAI pegged as if there is only 200ppm of co2 in the atmosphere. The actual level is some where between 800 - 1000 ppm.

    The SAI stops. In effect the earth goes from 200ppm to 800 - 1000 ppm in five years.
