I kind of get these kind of comics, but isn't the reality that all of humanity is still in a competition with eachother, and doing all the wrong things gives you more power than doing all the right things, so that's what continues happening.
In these climate debates the reality is that it's a global chicken on the road, we all go toward self annihilation at a steady pace, and the first who flinches and tries to take action will get taken advantage of and ruined. So it's slooooooow talks about doing tiny things and kind of maybe a bit cooperating while noone really wants to, because any advantage they can get over another country will be taken advantage of...
Maybe i'm a bit too pessimistic, but it's my assumption that things work like that, and then all this bullshit suddenly makes sense >_<...
