More evidence has been uncovered about Exxon’s disinformation campaign. This time the research was done by a group at Harvard, using methods commonly employed in the social sciences. The researchers “found a gaping, systematic discrepancy between what Exxon said about climate change in private and academic circles, and what is said to the public.” The information should bolster pending lawsuits against Exxon, and is available to anyone who is engaged in an everyday type of argument with a common denier.

A new report from Mark Jacobson shows the way to 100% renewable energy everywhere by 2050. The basic approach has now been applied in a completely detailed manner to the 139 countries that produce 99% of emissions. Economically speaking, the benefits that are foreseen far outweigh the costs. One interesting side benefit is a calculated 23% reduction in total global energy demand simply because of the different practices at work.

In a complementary approach, a chemical engineer believes demand for electric power can be reduced 20% by applying proven new methods to a variety of industrial processes. He thinks all of the emphasis on carbon capture and storage, which is supposed to obtain a similar result, is by comparison a proven failure and a sad waste of time and money.

The story behind the 2C threshold that is meant to set limits on future carbon emissions. It came about in a very casual way and has no particular scientific foundation. James Hansen has argued convincingly that a CO2 level of 350 ppm, which has already been exceeded by a wide margin, is enough to pose unacceptable danger because of effects that became established at that point but will take considerable time to be fully realized. The principal example of that type of effect is sea level rise. It takes time for all that ice to melt, but once you have added enough heat to the oceans and the melting begins it will just keep on melting, plus there is just no possible way to quickly remove the buildup in ocean heat content. Hansen is quite confident that the rise will eventually reach 6 to 9 meters, or 20 to 30 feet, a good part of it in this century, which compares with melting events in the distant past when CO2 was even less than 350. By the same token, if we allow CO2 to reach 450 or so by virtue of the 2C threshold we could be committed to an eventual sea level rise of 60 feet or more, likewise unstoppable.
