How permafrost melting affects the “carbon budget.” Here it is all clearly spelled out. When you add feedback carbon to that which humans emit directly the remaining carbon budget gets used up much more quickly than advertised. The new studies on feedback carbon keep adding evidence that the numbers are large and getting larger. Robert does his homework well. Go ahead and open some of the links at the end of his post.

A new report about the rate of ice melting in Antarctica, credited to Princeton University. This one uses gravitional satellite data, which is said to have unique properties. The heavy ice loss in West Antarctica is confirmed, and accelerating as well, while a substantial portion of East Antarctica is gaining mass, though of considerably lesser amount. The area containing the Totten glacier, which has been melting from below, unfortunately was not covered by the study.

New polling shows a lack of concern over climate change among young adults. This comes as quite a surprise, perhaps because those who are concerned tend to be more visibly active, on average, than such folks in other age groups. A step-up in educational resources would no doubt make a difference in the poll results, supporting an assumption that such resources are not commonly found in today’s public school classrooms.

New study predicts a high rate of extinctions primarily due to climate change. This is a story that has been rated for reporting in many local newspapers—the Guardian’s post makes some more observations. I personally think that almost every species is being stressed to some degree in this way, thus becomeing more vulnerable to a possible extinction which may mainly be attributed to some other factor.

Here is another story that has yet more to say about this important subject, adding some extra sources of information.

Efficiency gains in sight for perovskite solar cells. This relatively new and cheap material is found to have natural defects which reduce performance, but can readily be overcome chemically, which would bring efficiency yet closer to that of silicon. As a matter of further interest one individual, a graduate fellow, “estimates there are more than a thousand laboratories around the world currently researching the semiconducting properties of perovskite materials.” That should tell you something about where this may be heading.

Tesla’s new battery for home and business use is described. Apparently the pricing is attractive, but it is also true that plenty of competition is expected. The potential market for the next several decades is absolutely huge, and it looks very much like it is almost sure to take off, giving a good boost to wind power as well as solar energy.
