• climate change;
• income inequality, although by now it just sounds like an overly politically-correct relabelling of "law of the jungle"
And no, it doesn't even matter whether the rise in temperatures is man-made or not, so opinions about the "cause" are useless (the science is clear anyway…).
What matters is that 1. temperatures are rising, 2. it's a bad idea to worsen the trend (unless we suddenly start appreciating tropical storms and destructive weather, a lot more).
So no matter your theories about the cause of point 1, we still need to act about point 2… like here&now, not by 2020! And any blind spot about short-term "economic growth" and other "we cannot afford it" will cause dramatic consequences for millions of people (primarily the poorest, unsurprisingly), which will ultimately hurt the supposed "economic growth" (and increase inequality!).
