At some point it might even need to become a national security / defence force issue.
I mean, what was the point of all the wars, death and destruction if the military just allow themselves to suffocate? That would seem like a strange end.
Well this is an astonishingly clear example of corruption of our political system by the fossil fuel industry. Even in nations where militaries pretty much get what they ask for, almost regardless of budget (eg. the US & Australia), they are waved off by governments when they put climate collapse forward as a major security issue (which they often do).
