Until big governments and companies perceive that they can benefit by properly addressing climate change, nothing will happen. I suspect that big oil will see this as a business opportunity because developed countries will need more oil to run more potent air conditioners. The populations of under developed countries will start to shrink because they will not have the resources to protect their population from the heat. This will be a boon for the big companies because there will be less resistance as basic resources are stripped from the shrinking countries.

Until big government and company boards are replaced by younger, more environmentally aware types, nothing will change. Unfortunately, this will require decades. I don't know if we have enough remaining time to avoid crossing over into the point of climate no return. But this will not matter to the current elite because they will retreat to the expensive bunkers that they've been building.

Maybe solar power can replace much of the oil energy base, but big oil has had more than a century head start building iron clad relationships with the elites.

However, none of this begins to deal with environmental damage done by plastics and nano particles.
