Scientists honor Iceland's first glacier lost to climate change with plaque, eulogy. In the next 200 years all our glaciers are expected to follow the same path. "This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it," it reads.

I'd say your estimates are right if things progress every year at the rate of 5x worsening each year. California will have another worse shortage of water within the next 5 years but not be completely out. India though, I can't say for certain but they have a chance at saving themselves but y'know. A good portion of humanity will survive the next 10 years, poverty will grow surely in the world but we will live on just with much more problems . I'd say as it is now we are going to be absolutely screwed unless we figure something out by 2040-50, which even then is like a 5% chance. Best of hopes for the world though. I'm not all that knowledgeable so I wont speak on crop failure but I hope we figure something out with that though.
