Disappearing Act

Filed under: Extinctions

The truth about species evolution and extinction is that humans are neither the question, nor the solution.

To what degree does human-influenced climate change impact species evolution and extinction? A great many government officials, scientists, and the media would have us believe that our role is significant. But climate change has been occurring naturally over eons, and species have emerged, evolved, and disappeared on their own since the dawn of time.

Drought Doubt

Filed under: Droughts, Precipitation

The New York Times makes, but doesn’t test, a hypothesis that the drought in the western United States is related to human-caused global warming. Our tests prove it false.

Is the current five-year-long drought in the western United States linked to anthropogenic global warming? The masthead editorial in the May 10 New York Times leads its readers to believe that’s the case. Think of their supposition as a scientific hypothesis. One that you can test.

Assault From Above

Filed under: Satellite/Balloons, Surface

Nature authors make an assumption that defies the laws of physics. But that doesn’t stop them from concluding that the satellite-based temperature record is dramatically cooled by the atmospheric layer just above it.

It’s common knowledge that the satellite-based temperature record of the earth’s lower atmosphere shows much less warming than surface observations or climate model predictions for the past 25 years. The big question, though, is why. A new study in Nature magazine claims the satellite measurements are in error because they include a cooling effect from the atmospheric layer just above it.

But in formulating their case, the authors assume the impossible.
