Solar cells are continuing to improve. The world’s largest producer of solar panels, based in China, is not standing pat. The advances they report are especially important for growing the rooftop market. Jinko keeps setting world records for efficiency while maximizing manufacturing processes that hold down costs.

The latest from Bill McKibben, in an interview with Deutsch Welle. His point that we need action that matches the scale of the problem is smack on target. The problem has become monstrously large, and is more easily visualized. He thinks holding the temperature gain below 2C is technically achievable, but—“Is it politically feasible? That depends entirely on whether we can build movements large enough to break the power of the fossil fuel industry that holds us where we are.” He correctly shows that individuals have very little power to be effective unless they connect with others as part of a movement, even at the local level. (Or at the political level, as we saw on Tuesday.)

A committee headed by a preeminent scientist has issued a report to the UN that everyone should read. Professor V. Ramanathan is one of the few scientists who can articulate the “big picture” of climate change and its remedies in a completely inclusive manner. The report posted here offers the best example of such that can be found, and it is not even two months old. You would do well to first scan it, bookmark it, and then take whatever time is needed to absorb everything it has to say, which is a lot. For a very quick summary, life on our planet, including human life, is in deep trouble and on the very edge of getting much deeper. At the moment the situation is not hopeless, but it will soon become that way if appropriate action is not taken. A detailed plan of action is laid out, divided into three main categories, all critically important, none of them easy. The report includes a foreward by Nobel prizewinner Paul Crutzen, who endorses the program but (like Bill McKibben) has some doubts about the willingness required for implementation. The report is not just about action. It has some up-to-date facts and figures and some information from recent studies that has not yet been incorporated into climate models.
–Here is a different kind of introduction to the report, containing some useful background material relevant to the cloud studies that were included, and more.
