As another COP approaches can humanity divert the short term fossil fuel magnates to invest in sustainable fuels.

While the exact time scales and outcomes are hard to be exactly predicted I think few scientists still deny that we are in deep trouble and like all such catastrophes its time to put the brakes on? In rich countries where more women finish high school and many go to college have far fewer children

I've flown 3 times in last 3 years and driven my cars barely 30k to have annual service, just keep them for emergency/tree planting , however probably a dew 1000s on low fuel use Bikes, yet my desire to go off grid is undermined by the very long amortisation of the fixed costs plus inability to "reverse meter " into the Thai grid.

I think I'd need to live another 7 decades to make a new electric car offset my 100 liters of fuel per year,

Enough of my modest attempts to do the right thing, refuse plastic wrap and packaging is small potatoes in the bigger picture.

With sufficient incentives electric planes, merchant shipping are viable, China India and The developed world plus Australia need be goaded towards a sustainable footprint.

I have high hopes for Nuclear Fusion once Tokamak harnessed to scale but not for a generation at least.

Changes in water tabels , volumes, timing and potability esp enhance mass migrations and crop failures at a time when mouths to feed are booming esp in Africa. Nigeria to surpass USA then EU in population, places like Lilongwe will have more people than Paris or London, albeit in squalor.
