What’s new and interesting in the IPCC synthesis report?  The final segment of the latest IPCC report has just been released.  It includes some conclusions that are new to these reports but are otherwise quite familiar because they reflect views often expressed by a good many leading scientists.  Apparently the scientific group was able to bypass the usual politically motivated editing on this occasion, as they had promised to do.

Still, IPCC documents, including this one, are always conservative about making forecasts.  Stefan Rahmstorf, who is much involved in their writing, explains why.  This story also includes some interesting details about how projections for sea level rise in this century are being presented—in a way that is much too conservative.

Bill McKibben’s reaction.  McKibben, a well-known climate activist, is well aware of the potential held by renewaables, and where the trouble now lies.  “Our political leaders could do much more, of course. If they put a serious price on carbon, we would move quickly out of the fossil fuel age and into the renewable future. But that won’t happen until we break the power of the fossil fuel industry.”  Is he referring to campaign contributions?
 —–
Update on the utility cost of solar energy.  “Brazil has already found that wind and solar are both cheaper than building new coal or gas fired generation.”  The same thing is happening in other places, including India and parts of the U.S., even without subsidies.  It would also be true in Australia, were it not for the aggressive obstructionism of government policies.
 —–
Biofuel derived from algae.  This report of an activity that has received little attention comes from a research group in Australia.  “At the commercial scale, Muradel expects production costs would be on par with the cost of producing fossil fuels for transport.”  Most such ventures have failed, but this one seems to be making progress, and has been able to attract funding.  It would be mind-blowing if it succeeds.
