We're looking at an exponential curves here. And when it comes to exponentials, a few years make a tremendous difference. Would it be better if we had responsible adults in charge over in the US? Sure, but here is hope yet, despite them.
Don't get me wrong, it's not all good, we will have serious problems, no doubt. But all gloom and doom, all the time is in the same category as outright denial - it's an incentive to do nothing and just sit back and lament on how f-ed up everything is and nothing can be done about it. Which is exactly the opposite of what we need. We need people to know that things can change for the better, to be energized and actually start working on solutions. Because solutions do exist.
