Well.. for both your points here there are no guarantees. Progress isn't linear and just because we can adapt doesn't mean we will.

What is known is that our entire eco-system is failing to adapt fast enough to keep up with the rate of change - what makes you think we can beat it?

Its disappointingly reductive to throw the towel in and, really, that point of view is no better than 'the world is ending in 12 years'

To deal with a problem you must first acknowledge that it exists - any action is clearly going to beat sticking ones head in the sand.
