Global warming and global climate change is real and itโs going to happen. We wonโt do much to stop it. 
I doubt that alone will cause the extinction of humanity. No, if that were to happen in the near future it would probably have to be similar to how the dinosaurs (sans avians) went extinct โ a combination of global calamity like an asteroid strike, climate change and contagion. Or this.
We could get that with a nuclear war in combination with climate change, which isnโt too unlikely, but letโs stick to climate change for the moment.
As noted, climate change will happen. Weather patterns will be altered; seas will rise; famines are inevitable.
But other than those for sea level rise, I wouldnโt put too much faith in regional-level models for climate change effects. Those look pretty iffy and contingent to me, especially since never in
the history of the planet has carbon dioxide risen so quickly โ that we have good records for, anyway.
Which actually makes it worse not better, by the way! It means we donโt know what the fuck is really going to happen, but thereโs not a bit of a chance itโs going to be good.
The do-nothing crowd apparently also doesnโt believe in insurance or any other planning for the future, either. I know they are motivated by greed and are influenced by propaganda, but itโs so hard to understand how a group of people can be so resolutely idiotic.
Well, at least be consoled by the fact that most of the people reading this blog will be dead when things really get bad. Itโs your children and their children who will be climate refugees, starving to death in Anchorage or St. Petersburg or Stockholm.

Physical attraction (for both sexes) is probably at least partially based on using phenotypical proxies for genotypical health and fitness and is not acculturated. Iโd guess 80% or so, but who really knows.
