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.…

Sudden Jump In Published Findings on Tipping Activation

Bruce Melton PE, Climate Change Now Initiative Science is slow. It has been slower than climate change for decades and as that science has warned, if we did not act promptly and appropriately, the speed of climate change would increase further and dangerously. We now find this future…

Natural Systems’ Sequestration Failing

Image: permafrost thaw in Southeast Alaska At some point in the future, our climate culture has suggested that effects of warming will become so influencing on Earth's carbon balance that our natural sinks will slow and possibly reverse. This point has likely now passed reports Curran and Curran…
