How likely is this scenario? Global warming at 4C

The unfettered fatuousness and borderline incoherency displayed in these posts is so appallingly counterfactual it is difficult to read them as anything other than a poor attempt at satire, or else intentional misinformation. Setting aside the fact that the global climate circulation models and the IPCC and other reports that reference provide quantitative estimates which are evaluated for their impact upon agriculture, sea level rise, livability, et cetera, rather than just giving the qualitative result of “bad”, the feckless appeal that those concerned about climate change are sorely misinformed and need to read a textbook would appear to ignore the fact that the overwhelming consensus of meteorologists and climatologists—some of whom have literally written the textbooks referred to—is that climate change is real, demonstrable, and will have dramatic impact upon agriculure and habitibility, an opinion shared by the US Department of Defense considers climate change to be not only a major long term threat to national security and international stability but also a “present security threat” that has been integrated into the planning of all of the combatant commands. The idea that a rise in average global temperatures just means that it is consistently just a couple degrees warmer overall belies an utter lack of comprehension in climate behavior and meteorology.

As for the notion that everyone (in the continental United States) can just migrate up to Alaska as some kind of absurdly reductionaist solution to the multitude of impacts of temperature rise and attendant climate changes, Alaska is actually currently suffering the most pronounced effects of climate change including permafrost melting, coastal erosion, and habitat reduction. Notwithstanding the logistical problems of somehow migrating more than three hundred million people to Alaska, or what to do with the majority of the world’s population that lives in low laying and coastal regions directly impacted by sea level rise, the food security and other stability impacts of global climate change make any simplistic solutions and casual dismissal of such changes as something to be addressed as hoc as benighted foolishness of the most obtuse kind.
