Pielke train wreck

Tim Lambert at Deltoid discussed the train wreck surrounding Roger Pielke. Much of the similarities between ID Creationists and Global Warming Deniers like Pielke seem self evident, including a confidence not supported by the actual data that their side is correct. In the case of Pielke he confidently stated that the model predictions for the global warming trend were not consistent with the actual data.

Of course, not only were the data consistent, but Pielke did not even know which statistical test to apply to show support for his thesis

And yet, there seem to be some people who have come to believe the arguments by Global Warming Deniers, and it should not come as too big a surprise that there is a significant overlap between those who support the scientifically vacuous position of Intelligent Design and Global Warming Deniers.

Target Atmospheric CO2: Where Should Humanity Aim?

I have found that the same ignorance that surrounds evolutionary theory extends often to the issue of Global Warming.

James Hansen et al have released a report outlining the case for CO2

Paleoclimate data show that climate sensitivity is ~3°C for doubled CO2, including only fast feedback processes. Equilibrium sensitivity, including slower surface albedo feedbacks, is ~6°C for doubled CO2 for the range of climate states between glacial conditions and icefree Antarctica. Decreasing CO2 was the main cause of a cooling trend that began 50 million years ago, large scale glaciation occurring when CO2 fell to 425±75 ppm, a level that will be exceeded within decades, barring prompt policy changes. If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm. The largest uncertainty in the target arises from possible changes of non-CO2 forcings. An initial 350 ppm CO2 target may be achievable by phasing out coal use except where CO2 is captured and adopting agricultural and forestry practices that sequester carbon. If the present overshoot of this target CO2 is not brief, there is a possibility of seeding irreversible catastrophic effects.
