<span style="font-size:12.0pt">4. By the time you read this COP 26 will have ended with approval of a text listing agreements. It will still be worth taking a look at the issues the delegates faced as they worked on the final draft. A central problem is the
debt, if any, owed by the industrialized nations, largely responsible for the climate crisis, to the poorer nations which are suffering some of the most dire consequences.

<span style="font-size:12.0pt">5. And now that COP 26 had ended (since the previous item was posted—it ended last night, in fact) the reactions are being recorded. They range from outrage and despair (“utter betrayal”) to measured hope (we “imperfectly yet
doggedly and collectively began digging ourselves out of our mess”) to celebration (“we are in fact closer than we have ever been before to avoiding climate chaos and securing cleaner air, safer water and a healthier planet”).

<span style="font-size:12.0pt">6. My take: the most significant developments have taken place during but somewhat outside the conference, and a couple were occasioned by it. 1. The two largest emitters, China and the US, have pledged to limit heating to 1.5C.
That means that, among other measures, China must dismantle first its coal plans and then its plants, and the US must cease taking its orders from fossil fuel interests.
<span style="mso-spacerun:yes"> </span>2. Over 100 nations have pledged to cut methane emissions 30% by 2030. It may prove impossible to meet that target while maintaining a viable commercial methane industry, which will be brought to face its long-term lies
about leakage and the dwindling economics of using methane for peaking power.</span>

Norwegian scientists have developed a process to double the efficiency of solar cells at little additional costs with nanowires of gallium arsenide grown on top of the standard silicon cells. The effect, if the process is commercialized as predicted, would
be to cut the cost of solar power in half. The effect of that would be the end of fossil fuels for commercial power.
