<span style="font-size:12.0pt">1. A new process uses liquid gallium to convert CO2 to oxygen and sheets of useful carbon. The process is 93% efficient, relatively cheap, and works at room temperature; it is being commercialized. The process seems most applicable

<span style="font-size:12.0pt">2. Steve Cohen of Columbia U’s Earth Institute observes that the blocking of the Clean Power Program from the administration’s reconciliation bill need not mean giving up on accelerating the energy transition. In fact, punishing
reluctant utilities through fines might have done more harm than good. If we can support the means of transition (such as grid refitting) and such tools as a national green bank and state renewable power targets we may achieve satisfactory progress.

<span style="mso-spacerun:yes"> </span>56 million years ago at the Paleocene-Eocene Thermal Maximum when volcanoes led to a greenhouse event like the one now underway recovery of the atmosphere took 20-50,000 years. (We could speed this up through a good carbon
capture and sequestration program. Kelp permaculture cleanses the oceans as well.)
