If you were in charge tomorrow, what concrete, measurable milestone would you have the most the talented scientists and 0.4% of GDP go to solving?

There is a fundamental in flaw in photosynthesis where it gets less efficient as temperatures rise (given the current O2/CO2 ratio). It’s a giant problem, and is exacerbated by projected droughts in many areas. IMO, this is one of the big problems humanity will have to solve.

TIL. So this means global warming indirectly lowers crop yield?

I found a meme that actually does a good job. C3 photosynthesis is what most plants we cultivate use to form sugars. Oxygen can react with the CO2 binding agent(Rubisco), which forms phosphoglycolate. It’s a potent inhibitor of key processes, and requires giving back a carbon atom to neutralize

It’s too complicated to boil it down to a general statement. There is a temperature where Rubisco-carboxylation peaks. As temps rise, anywhere below that temp will see crop yields rise, anywhere above it will see yields drop. The problem I referred to also depends on water supply, so that must also be considered.
