Highlighting the importance of the new sea-level study by DeConto and Pollard. (See yesterday’s Climate Letter if you are new to it.) The study has drawn a great deal of attention from outside scientists as well as the press. It is impressive because it provides detailed mechanisms for how ice shelves and ice sheets disintegrate, sets up models based on all the usable information and tests the models against known happenings in the past. It does everything in ways that the IPCC is looking for, but did not have available for its much too conservative report in 2013. Here are several links to reviews and commentaries that tend to contain different elements of evaluation as well as detail. We’ll start with one from Joe Romm:

This one has direct quotes from one of the authors, Robert DeConto, about how the work was motivated:
A review with some broader perspectives, written by two scientists for an Australian publication:

An analysis of new coal plant construction, and what it means. This is a clearly written story by Carbon Brief, with activity in many individual countries broken down. What it mainly demonstrates is a state of confusion, with too many new plants still being built while existing plants are being less fully utilized—plus all those pledges from Paris to attend to. The biggest unanswered question that I can see concerns the future of new plant construction in countries that are largely undeveloped and have ambitious plans in the works, starting with India.

Research on the inner workings of a solar cell. You can learn here about how newly created electricity is carried out of most cells. New knowledge points toward the manufacturing of cheaper and better cells.

New emphasis on energy efficiency. Opportunities exist wherever you look, offering one of the easiest and cheapest ways to bring down emissions. This is especially relevant in countries like the US, where wasteful habits have been bred by a long-time abundance of cheap energy gained from fossil fuels.
