I`m not a climate scientist so don’t expect me to reproduce all the technical details here, but in short both the worst case scenarios and best case scenarios for climate change seem rather unrealistic now, at least according to this article. If I got this right we’re expecting a 2° C increase in global temperatures, which means that major cities along the coasts will still get flooded, but total civilizational collapse seems unlikely.
Of course this is still all up in the air, and a lot of it depends on how the newly industrialized economies of the world regulate their carbon output, and other findings suggest we’re already fast tracked for a worst case scenario outcome, so make of that what you will. The point being that what will happen in the next few decades is up in the air at this point, no one knows, anything can happen, and what happens is ultimately up to us.
So don’t fall prey to the denialist, capitalist serving bullshit that is eco-pessimism, but don’t get your hopes up either, take action is all I`m saying, that’s what ultimately matters after all.
