Global warming and global climate change is real and it’s going to happen. We won’t 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 – 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 isn’t too unlikely, but let’s 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 wouldn’t 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 – that we have good records for, anyway.
Which actually makes it worse not better, by the way! It means we don’t know what the fuck is really going to happen, but there’s not a bit of a chance it’s going to be good.
The do-nothing crowd apparently also doesn’t believe in insurance or any other planning for the future, either. I know they are motivated by greed and are influenced by propaganda, but it’s 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. It’s your children and their children who will be climate refugees, starving to death in Anchorage or St. Petersburg or Stockholm.
