Behavior of Greenland’s ice sheet explained. Lots to learn here, with a focus on why some large melt ponds on the surface quickly drain. There is an excellent video describing the layers that make up the ice sheet. It makes clear how little ice was left at the end of the last interglacial period, more than 100,000 years ago, at a stage we are just now ready to repeat, in our own special (very fast) way.

How to enforce new climate rules (NY Times). The article is about the application of game theory to climate abatement negotiations, showing some major reasons for their past failures. What may be the best solution: “In an article published in April in The American Economic Review, Professor Nordhaus proposed just such a climate club, in which countries committed to reducing carbon emissions would impose a uniform tariff on imports from nonmembers.” A bold idea, whose time, I

An evaluation of the hope for a rapid transition to renewable energy. This is by Kurt Cobb, a writer I generally admire for his realism and common sense. This piece is no exception. He shows why it may be a long wait, maybe too long, for renewables to completely take over from a very modest current level of penetration. Another way to reduce carbon emissions effectively is to reduce our excessive need for energy usage, on a dramatic scale, which is very doable, but will take a degree of organized effort well above what is now being done. Carbon taxes would certainly help.

Book review—“Overdevelopment, Overpopulation, Overshoot,” by Adam
Johnston. This book mainly serves as a reminder that rapid population growth is incompatible with unlimited economic growth, considering the Earth’s limited available resources. The book appears to have more to say about the problems we face than their solutions, perhaps because it is so hard to find solutions that are easily accepted everywhere.
