Nuclear winter will definitely cool the planet, especially if hundreds of bombs are used … but it will mean turning the planet into a snowball.

Nuclear winter will mean destroying most or all plant life for years or decades or even a century. Many people will die either from the bombing or the radiation but the majority will die slow deaths from starvation years after.

Sure there may be some wealthy important people that will hold out in bunkers and underground shelters but once their food supplies run out, they’ll have to come out, and when they do, they won’t find anything. The survivors will have to raise new generations with far less, even if they do survive living in an irradiated landscape which won’t be safe for hundreds of years.

The planet will definitely be cooler … but it won’t be liveable for humans.

This isn’t a race to save the planet by cooling it off, the planet’s fine. It’s dealt with disasters and changes far more destructive than us.

We need to do something about the climate to save ourselves and our species. Nuclear war places us in as much danger of extinction as doing nothing about climate change.
