I think many already realize how bad humanity's usage of oil has been for t0+100 humanity. And let's not even talk about t0+200 humanity. The ascendance of oil has been a relatively recent phenomenon in human history, and it's pretty safe to say that even with some of the brighter minds of humankind guiding its usage, we still managed to f things up pretty badly. The bigger picture seems to be that humanity isn't so good at managing itself. Perhaps a major advance in AI is the only potential salvation for this timeline.
