From the half full glass perspective, it's worth noting that things are changing. Solar and wind are now competitive on price (I loved how you could see the solar eclipse in German electricity output earlier this year), and are rapidly gaining social acceptance. Energy storage is playing catch up but is making progress. These 2 things will allow the majority of ground transportation and consumer electricity generation to move from fossil fuels (10-30yr timescale). Then we need the material science folks to figure out how to remove oil from the product cycle... I have no idea where we are in this as it seems like a particularly tricky problem.
Of course, all of the above doesn't matter to a degree as damage has been done and even if we stop being naughty right now it will would take the planetary ecosystem ~ 20 - 50yrs or more to find a new quasi-equilibrium, e.g., our understanding of how the oceans store and transport energy is currently lacking.
Hmmmm, maybe that glass is half empty afterall...
