The potential impact of climate change and other developments on the Mekong River Delta. This is the first part of a major in-depth study. One urgent problem is that a 1-meter rise in sea level, expected in this century, will displace 3.5 to 5 million residents.

How global temperatures depart from normal each year, charted. In this post, third chart down, there is a good snapshot of the total anomaly factor each year since 1950 due to the effects of El Nino or La Nina, large volcanoes and solar radiation changes, which either add to or subtract from the more steady pace of the greenhouse gas effect. Only the biggest anomalies are explicitly identified, which is unfortunate. (For example, 1957-58 readings were affected by a quite strong El Nino event.) The anomaly line should fall back in 2017, but no one can safely predict how far.

A primer on the “Anthropcene.” This is an exceptionally neat explanation of what the concept, still far from being resolved, is all about. We have no way of knowing what the next “geological age” is actually going to look like, over at least the next million or two years. We can only suspect that today’s humans have had a big hand in getting a probable brand new age off to a rousing start. We have almost certainly put an end to the Pleistocene (ice age) that began 2.6 million years ago, and thus erased the current minor subdivision, the Holocene, which up until now has been thought of as a typical “interglacial” period. Also, we have indeed made profound, long-lasting changes on the Earth’s surface, just like the meteor that ended the Cretaceous era, 66 million years ago, and left behind a permanent scar in the form of an iridium layer. The era that followed was not named after the meteor, so why should we now name a future era after us, when we may not even be around to enjoy the acclamation? There are probably going to be big changes in the overall makeup of the current biological system, and we should just concentrate on preserving as much of it as possible in a healthy state, ourselves included.

An international agreement aimed at reducing aircraft emissions. The nature of the problem is recognized, and there is a strong show of good intentions, but not much more. The last two paragraphs in this story provide a proper evaluation.
