Due to higher CO2, more heat is captured in the atmosphere. Early on the naive messaging of that was “global warming”.

That added energy is changing the climate but it does not just mean that everything gets evenly warmer. The added energy means that some places get warmer than other. The differences mean that some areas get dryer and some get wetter.

Those increased differences in temperature and moisture result in storms and other weather events that have more energy and cause more problems. The large scale weather events like the Jet Stream or El Niño become more erratic . You get bigger storms, bigger floods. Sometimes you get bigger dumps of snow with the greater moisture. Some places get less moisture and are warmer for years at a time and fall into drought.

Those erratic weather and climate changes cause problems for humans, animals, and plants. More food sources underproduce or are destroyed. Hunger drives people to migrate. That causes disruptions in neighboring nations. Politics becomes more strident and antagonistic. Small wars eventually break out.

Yes, the messaging has changed a little over the years. That is partially as scientists have studied this more and learned more about both the primary and secondary effects of climate change. The media simplifying it so the public can understand has adjusted the terms they use as our understand realizes that this is not just a matter of simple warming but of a complicated system getting more unstable.

Good description of what awaits.

> Small wars eventually break out

I wonder if that isn't happening already here and there.

Bigger ones? What'll happen when areas large as a country, becomes mostly uninhabitable.

One more thing: There might be more authoritarian regimes in countries not affected that badly by the climate changes -- because the migrants will want to go there. And then the voters in those places, choose more brutal and authoritarian governments who build borders and use violence to keep the migrants away.

So, more war and dictatorships in the future, is one scenario?

Yes, I didn’t want the person I was responding to to say that I was being dramatic but when food and water are unstable and migrations disrupt those around them, societies get more desperate and can become more aggressive and war is the result.
