Update on the cost of climate change for Southern Africa. El Nino officially ended in May, but there are still no clear signs of recovery from the extreme drought experienced by almost the entire southern third of the continent.

Warnings about the potential for imminent extinction of many large species of mammals. A team of over 40 conservation biologists who are in position to see it happening have joined together to make a statement that raises a high level of alarm. These extinctions are very likely to happen unless some unusually strong and urgent action is taken to reverse the trends. The focus here is on human activities that are not climate related. However, it is easy to see that the same lack of leadership and lack of intense interest and resolve on the part of the general public are operative in this sector as they are with respect to climate solutions.

A new type of legal investigation seeks restitution from the effects of fossil fuel pollution. It’s hard to see how it can go anywhere, but this is not a frivolous case and the way it proceeds should be educational, perhaps setting a useful example for related actions in the future.

Climate science: An interesting point about how the carbon cycle works has been demonstrated by ancient sediments. The point is that hot air temperatures due to excessive CO2 produce more rainfall, thus more weathering of rocks, leading to more growth of plankton in the seas and more sequestering of carbonates on the ocean floor, thereby causing drawdown of much CO2 from the air by a long and slow procedure. This happened in the aftermath of the PETM, and should eventually happen again (if the ocean water is not too acidic for the plankton shells.)
