The poles would still prevent sea level rise. Or avoiding melt of the land based ice sheets would anyway. I agree with you on solving root causes. If we don’t, the oceans will acidify with co2 and there may also be bad effects from higher co2 in the air. Emerging studies show cognitive declines. That said, both of those are slower moving crises to some extent. We may face acute challenges from excess heat and changing weather patterns. So it’s possible we’ll require an emergency stopgap while we fix the underlying issues.
