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
Переглядів 34 тис.Рік тому
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. As temperatures rise, t...

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

How snow loss is fueling the West’s megadrought

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. But upstream, a much larger but lesser known source of stored water is also disappearing: mountain snow. This is how climate change is throwing one of the United States’ most critical sources of water out of whack...

    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.

    For home use, solar seems by far and away, the most practical. Forget 'grid tie". go with battery and inverter, with a charger connected to the grid, if needed. According to my calculations, a 24 hour battery will produce the lowest cost of energy storage, whether you choose Lead Acid, or Lithium.

    So you’d rather genetically engineer the foundation of our food chain than correct human-caused climate change? We know how to fix climate change, which is the source of the problem. Instead of manipulating the fundamental enzymes of plants, which will probably just make rich people richer, maybe we should look at the source of the problem. Fix capitalism, food waste, and fossil fuels before elegant, tried and tested, plant physiology. I can see the argument that this could be just 1 of many tools to help us in the ongoing struggle of climate change but…come on. With our track record of genetic engineering, human monetary profit for the few will outweigh ethics, serving the marginalized, and multi-species survival.
