If climate change is not dealt with in the immediate future, it will be a huge problem around 2100, which will likely correspond with another Crisis Era. Inundations of property will put huge stresses on governments to relocate people and economic resources. Because much of the world's food supplies now come from low-altitude flat lands, food stress could be a big problem. Add to this, agricultural belts will shift as climate belts shift. The potato belt could be pushed into the nutritive deserts of the current zones of taiga. Tropical diseases will start appearing in places not-so-tropical, like Kentucky and northern Italy, as winters become less severe. Tropical diseases are delicate things, either they or their vectors unable to withstand real winters.
Energy use that might decline due to more efficient use of vehicles and more efficient lighting will get a boost from air conditioning as Texas summers start appearing in Michigan and Minnesota.
Legal anarchy, mass dislocations, and stress from reduced supply of food will bring out the worst in human nature -- even pogroms and genocide. If you thought that Hitler-like figures were obsolete now, they might become much more relevant and dangerous around 2100.

The ideal subject of totalitarian rule is not the convinced Nazi or the dedicated Communist but instead the people for whom the distinction between fact and fiction, true and false, no longer exists -- Hannah Arendt.
