Perspective on the Louisiana storms and flooding. It’s all about the general increase in extreme weather events that is a regularly predicted effect of global warming. When something happens with increasing frequency you need to change the definition of what it means to be extreme. This is the eighth 500-year (or more) rainfall event just in the US in a little over one year, and they are happening elsewhere at much the same rate.

The dynamic growth of air-conditioning. This excellent report provides an abundance of information, and the numbers are staggering. Most of the new demand is coming from developing countries, particularly China, and of course rising temperatures are very much a factor everywhere. It also complicates the issue of securing agreements on the reduction of HFC emissions.

What to expect next from the IPCC. There are a host of ways it could improve on communications, mainly by speeding up the delivery of new and credible information. We should see some progress toward that end, in the way of limited special reports, with a date of 2018 mentioned for one. I believe they could do better, even if only as a way to signal growing urgency toward the need for gaining quicker solutions to the problems involved.

The problem of “marine heatwaves” is getting more attention. The number is growing and they last longer, while getting more intense, all of which are matters that scientists are saying go well beyond what climate models have predicted. That in itself is disturbing, in part because it makes you wonder why the models are so conservative, and where else they could go wrong. The damage is substantial, both within the oceans and by way of altering weather conditions in many unfavorable ways in the atmosphere above.

An interesting new discovery that may increase the capacity of lithium-ion batteries. A change in the electrode material from graphite to extremely thin silicon is said to make a difference that would yield six times more capacity than today’s standard. This work, still under development, is being performed by a team in France. So far, the level of verification is low but this will be worth watching for more news.
Here are a couple of more futuristic ideas for energy storage that would be interesting if they pan out:
