I'd really appreciate a sentence or two on each of the following questions:

  • What is termination shock risk?
  • What is the main concern with unilateral deployment?
  • What is the worry re: interstate conflict?

termination shock: the worry that after SAI is deployed, it is for some reason stopped suddenly, leading to rapid and large warming. Unilteral deployment: the worry that a state or other actor would deploy SAI unilaterally in a way that would damage other states

The concern I have about interstate conflict is that: SAI will have to be deployed for decades up to a century to provide benefits. Over this period, there would need to be global agreement on SAI - a technology that would have divergent regional climatic effects. If there are adverse weather events (caused by SAI or not) victims would be angry and this could heighten interstate tension. Generally, maintaining agreement on something like that for decades seems like it would be really hard.
