Photosynthesis has a problem
The enzyme RuBisCO is essential for photosynthesis. But it kind of sucks at is job, and it’s getting worse with extreme heat.

The very bad math drying up the Colorado River

California and Arizona are currently fighting each other over water. But this isn’t new - it’s actually been going on for over 100 years. At one point, the states literally went to war about it. The problem comes down to some really bad math from 1922. To some extent, the crisis can be blamed on climate change. The West is in the middle of a once-in-a-millennium drought.

Globally, we’re expected to reach 40 million e-bikes sold in the year 2023. It’s easy to see why.

Lake Mead is America’s largest reservoir, supplying water for 25 million people across the southwest. It’s also drying up - a kind of poster child for the ongoing drought in the West.

    Yeah, a hotter world isn't the end of agriculture lmfao. Average global temperatures had reached up to 30 celsius, whilst today it sits at 14 celsius. And yet, those prehistoric plants could support massive amounts of megafauna. You know, dinosaurs. I think we'll live.

    Interesting that when the earth was much hotter the plant life thrived and still does in our warming climate. Methinks the slight natural rise in CO2 is leading to the greening of the earth. Why do they inject CO2 into commercial greenhouse. We need more CO2 in the atmosphere. Not impressed by this research.

      It's not a natural rise in co2, it's human caused. The reason this specific time it's bad even though it's been warmer in the past is because this human caused warming period is causing temperature to rise alot faster than ever before, not enough time to adapt

      We've ruined a lot of habitats with relatively simple things, like farming, forestry, dams and irrigation - without directly intervening in biology of plants, only their habitat. This is going to wreak total havoc by comparison. Balancing ecosystems for our own survival needs most of that research to be regulated out of existence.

    Looks like Rubisco is a failsafe for too many intelligent mammals messing over the planet . More mammals consume more resources , creating more C02 which traps more heat - plants make less food - mammals starve and die, population decreases ,lowering demand for resources , reducing C02. Plants clean up CO2 to put the planet back in balance.

    Hysteria. We’ve always had flooding. The Netherlands are under sea level too. The problem is the pumps - the contractors did substandard work. When strangers do bad research on a place they don’t know we get bullshit on UA-cam. Katrina flooded us because of the Corps of Engineers - did you hear the MRGO mentioned? It wasn’t levy failures, it was Congress refusing to act while the Corp ducked the mess it made.
