I can accept “Saving the Planet” as a political slogan for those who advocate taking action to combat climate change – political slogans don’t have to be entirely accurate although I might argue that “Saving People” is more accurate. Because no matter how serious climate change gets, the planet will carry on.
Don’t get me wrong, I think climate change is really serious – we will see millions of deaths at least; quite possibly billions of deaths. And climate refugees will make the Syrian refugee crisis seem like just a tiny taste of what the real thing will be like. And some historians put the collapse of the western Roman empire down to climate change refugees – I don’t think it’s that simple but it was certainly a contributing factor. That is the level of disruption from climate refugees that we can expect.
And if you’re one of those inhumane nasties that imagines military level forces using lethal force to stop refugees, you can forget it – not only are there enough of us bleeding heart liberals who will shout “fuck that shit”, but it is doubtful that any level of military force could stop millions of refugees.
Climate change won’t destroy the planet; it won’t even destroy the environment. It will change the environment catastrophically and humans are to blame. Whole species will become extinct, but probably not humans; we’re too adaptable and we’ve survived through extinction events before (although sometimes only just).
But before anyone gets too complacent, if we don’t do anything, humanity will survive by the skin of its teeth – if just 90% of us are killed, we’ll be lucky. If we act today to make drastic changes, we might keep things down to just a few million dead; if we had acted back in the 1980s, that would be considerably less.
