By 2040, rainfall on wheat, soybean, rice and maize will have changed, even if Paris Agreement emissions targets are met; projections show parts of Europe, Africa, the Americas and Australia will be drier, while the tropics and north will be wetter.
Scientists have harnessed liquid metals to turn carbon dioxide back into solid coal, in research that offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere. The new technique can convert CO2 back into carbon at room temperature, a process that’s efficient and scalable. A side benefit is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles.
Researchers have proposed a design solution that could bring artificial leaves out of the lab and into the environment. Their improved leaf, which would use carbon dioxide — a potent greenhouse gas — from the air, would be at least 10 times more efficient than natural leaves at converting carbon dioxide to fuel.
All that is missing is the demand that the president declare a national emergency (as authorized under the National Emergencies Act of 1976) that explicates the gravity of the situation and proposes the full marshaling of the country’s resources (while we still have them at our command) to bear upon this civilizational crisis. Fat Chance.
