Ask HN: Questions about Global Warming

I trust the scientific consensus, that is, global warming poses a real threat. I've eagerly read the comments in https://news.ycombinator.com/item?id=13941923 as well as Dr. Guy McPherson's statements. Climate science is not my field, so I'd appreciate if you could answer the following questions. No sugarcoating. 1) What are practical, in hand solutions to such threat, if any? 2) How can I prepare myself to survive through the worst-case scenario? 3) Where's the best place to move preemptively? I imagine that the means of food production will be in the hands of a few countries.
