I guess I will break with the general consensus here - climate change has not, so far, changed my investment strategy, but that's partly because I don't know what else to do. I do feel significantly less confident in the idea or early retirement via stock market dividends, than I did, say, 5 years ago. The more I read about the feedback loops that are being triggered with methane release, melting sea ice, etc., I find myself questioning the logic of maxing out my 401k in stocks (or bonds or REITs for that matter) at the expense of other types of investment, in the future, and in the present.
On a very practical level, I've been wondering if a good retirement plan should involve having a piece of land somewhere and a capacity to obtain water and live off the grid. I'm not talking about a bunker full of guns, but I am concerned about food shortages becoming an issue sometime in the next, say, 10-20 years (no one really knows), due to agricultural disruption. I am not sure I want to live in a big city with nowhere to go in such an event. Of course, buying land costs money (and time), so there's an opportunity cost - money I'm putting into my 401k is not being put into other things that might have practical implications on my (and my family's) stability and security in the long term.
On a less practical but more happiness-level, I think, what am I forgoing now for a future retirement stache that may not exist. Should I (an my family) be saving less and enjoying ourselves more - not lavishly, but just, you know, taking more time off work, buying that canoe we always wanted, etc.
So, to answer the original question, yes, but I'm not sure what else to do.
