Something is Happening On the Sun | The Next Grand Minimum

All of these effects are unprecedented in the observational data and tells us that the Sun is changing in ways not seen before.  [Can we assume that CO2 is the cause?  Can I prevent these changes by buying a Tesla?]

The Blackboard » Pinatubo Climate Sensitivity and Two Dogs that didn’t bark in the night

Allowing for uncertainties in the temperature and flux datasets, the response from Pinatubo is compatible with a 2xCO2 climate sensitivity of between 0.9 and 1.7oC, with a ML value around 1.4 oC.

PBSG polar bear population assessment made simple | polarbearscience

In conclusion, it is apparent that the most recent subpopulation estimates for polar bears vary widely in reliability and accuracy and have done so both within and between subpopulations to varying degrees since the PBSG assessments began. Out of 19 subpopulations, four have no data and another four have inadequate data. Ultimately, the status and trend assessments reflect the opinions of PBSG biologists and are not necessarily based on scientifically-collected evidence. This may be the best available data but is it good enough to draw firm conclusions about the status of polar bear populations worldwide?

The Myth of Affordable Energy - Interview with Ed Dolan

Ed Dolan: If I were trying to make money by generating electricity with wind or solar, I’d be worried about gas. I don’t have all the relevant numbers at my disposal, but my gut feeling is that even if you price in full environmental costs for wind, solar, and gas—including environmental costs associated with fracking—gas is still going to be pretty competitive.
