It’s faced total Atomic obliteration

Lol, no it didn't. There was a threat of nuclear war, sure, but there was never anything close to atomic obliteration. Comparing cold war era nuclear worries to concrete damages by climate change is asinine.

The world war comparison is marginally better, but in both cases, those were human driven AND controlled events. Climate change is human driven, but we have absolutely 0 control over it and it will absolutely impact every corner of the globe much worse than any war we've fought.

The suffering that climate change has brought and will bring is like nothing we've seen before, and it can be hard to keep telling yourself every year that this will likely be the coolest summer of the rest of our lives.
