In my view, government has two important roles to play in this. The first is on the emissions side. As you know, climate change is caused by a build-up of carbon in the atmosphere, and that is primarily a result of burning fossil fuels. One that carbon in released into the atmosphere, it stays there for hundreds of years – by making the choice to continue burning fossil fuels today, we are heating up the planet for generations to come. Or to be more blunt about it, by continuing to burn coal, oil, and gas, we are ensuring that our kids and grand-children will be living on a radically different – and likely more chaotic – planet.
People generally move in climates where it's warm, but not too hot. That way they can hunt, raise livestock, and grow food for everyone. Also, it's just a nice climate in general to stay in. Hope this helped :)
