Looking at the geopolitical trends it seems that global consensus is waning, and that is why I think it will get worse before it will get better. Humans respond to crisis better than they respond to future imagined dangers. That doesn't mean that we shouldn't try to improve that, and developed economies should take a lead with that. But I think the only way to make developing economies take action is if developed economies take a lead and set an example. If people in the USA and Europe drive suv's (just a silly example) you can't possibly expect India (and others) to not burn coal and other fossil fuels to electrify and industrialise their economies. We have a long way ahead of us to get out of this rut and saying that we only need political will to solve the problem makes it sound easy.
