Climate change is not one of the things I see getting better.
Then it’s hard to be optimistic about the future - if we don’t make a drastic alteration to energy then we are heading for rises in temperature that are going to make some parts of the planet inhabitable,. leading to water wars and huge displaced populations moving north. This will play into the hands of right wing populists and the political system will be under the kind of strain we haven’t seen in a century. That’s for as long as we can keep what might still pass for civilisation limping along.
