What’s next for carbon removal? Undue Widespread Pessimism

Stratos, 500 million ton per year air capture unit by Occidental Petroleum in the Permian Basin, Texas What’s next for carbon removal? Undue false and widespread pessimism in the popular press. Companies have still drawn down only enough CO2 to cancel out a few hours of US emissions.…

Land Sink Now Degrading

Duffy 2021 reports that within the last decade, the average global temperature for the warmest 3-month period passed the thermal maximum for photosynthesis. This means that on average, photosynthesis has peaked with warming and is now in decline, despite broadly accepted projections that photosynthesis would continue to…
