Global nuclear war would likely be easier for the planet to recover from. Nuclear winter can last as long as a decade. Nuclear fallout 1 to 5 years. It's nothing compared to how long it will take to recover from runaway greenhouse effect. Venus never recovered...

Less than one billion years ago, the climate dramatically changed due to a runaway greenhouse effect. It can be speculated that an intensive period of volcanism pumped enough carbon dioxide into the atmosphere to cause this great climate change event that evaporated the oceans and caused the end of the water cycle.

It's going to happen in a billion years anyway, since the sun keeps getting hotter. But we have the technology to prevent it, we're just not willing to do much about it. It's a slow process, not something to worry about with 4 year political terms. You're not seeing much benefits short term nor more negatives short term. Long term planning seems a thing of the past where projects could last centuries. Now we need success right a way or loose interest. Doomed to keep heading in the same direction long term.
But sure, we and our children will have little problems. Our children a bit more, their children more, and so on. It's becoming a fact that the best period to be alive has peaked, things will be going downhill in the future.
