    “A Carbon-Sucking Startup Has Been Paralyzed by its CEO. Global Thermostat is America’s best hope to pull CO2 directly out of the air. Insiders say pioneering, brilliant co-founder Graciela Chichilnisky has held it back for years.” (Bloomberg April 9, 2021) https://financialpost.com/pmn/business-pmn/a-carbon-sucking-startup-has-been-paralyzed-by-its-ceo
    “Across the world, many countries under report their greenhouse gas emissions in their reports to the United Nations, a Washington Post investigation has found. An examination of 196 country reports reveals a giant gap between what nations declare their emissions to be vs. the greenhouse gases they are sending into the atmosphere. The gap ranges from at least 8.5 billion to as high as 13.3 billion tons a year of under reported emissions — big enough to move the needle on how much the Earth will warm.
    The plan to save the world from the worst of climate change is built on data. But the data the world is relying on is inaccurate.” https://www.washingtonpost.com/climate-environment/interactive/2021/greenhouse-gas-emissions-pledges-data/

    • Puzzling Evidence says:

      Virginia Tech researchers, in collaboration with Pacific Northwest National Laboratory, have discovered that key parts of the global carbon cycle used to track movement of carbon dioxide in the environment are not correct, which could significantly alter conventional carbon cycle models.
      The estimate of how much carbon dioxide plants pull from the atmosphere is critical to accurately monitor and predict the amount of climate-changing gasses in the atmosphere. This finding has the potential to change predictions for climate change, though it is unclear at this juncture if the mismatch will result in more or less carbon dioxide being accounted for in the environment.
      “Either the amount of carbon coming out of the atmosphere from the plants is wrong or the amount coming out of the soil is wrong,” said Meredith Steele, an assistant professor in the School of Plant and Environmental Sciences in the College of Agriculture and Life Sciences, whose Ph.D. student at the time, Jinshi Jian, led the research team. The findings are to be published Friday in Nature Communications. https://www.eurekalert.org/news-releases/948254

    Props to these amazing scientists… It just feels like there are too many of our species on this planet and we are running out of ways to hide from that. One question… what negative impacts could the buried solid pellets of carbon have long-term?

      Good question. Because of its centrality to many alloyed, modified, rewatted chemical structures, science and industry know more about carbon than most elements. It’s one of the fab 4 – CHON – considered to be the basis for modern chemistry and many of the essential molecular structures that got our species to modern times. I’d be concerned about relative ease of carbon linking up to compounds outside our control IF we didn’t already know so much about how and why to utilize/control its linking ability in the first place.

    Its good that they’re aiming for a carbon neutral output, but it said wee need to have a negative output. Carbon is one of the most versatile substances in the universe, there’s got to be something better to do with it than to put it back in the air after you went through all the trouble to take it out.
