Hooray for science!
So in order to reverse climate change, all we need to do is build a few thousand Tsar Bombas and set them off somewhere remote. Australia maybe? We've got to make sure we do a good enough job on the wildlife that there's no danger of any radioactively enhanced super-mutants though. I for one do not fancy coming across a 20m tall drop bear with a bad attitude. And the less said about Spider Kong, the better.
Come to think about it, the mutant soapstar / popstar cross-overs don't sound too appealing otherwise. Maybe make it 20,000, just to be safe.
