Null Hypothesis Rejected (99.9) for Contemporary Climate Change via Pure Statistics

Via Ha-Aretz:

Climate change is man-made, concludes a nonlinear physicist at McGill University, in a paper published in Climate Dynamics.

In a paper enticingly titled “Scaling fluctuation analysis and statistical hypothesis testing of anthropogenic warming,” Shaun Lovejoy can’t prove a negative – that humans aren’t ruining our planet. What he can do is demolish the claim that natural variability is the root cause of the warming world, not to mention extreme weather phenomena the world has been experiencing.

“This study will be a blow to any remaining climate-change deniers,” Lovejoy said in a statement. “Their two most convincing arguments – that the warming is natural in origin, and that the computer models are wrong – are either directly contradicted by this analysis, or simply do not apply to it.”

Lovejoy concludes that the null hypothesis is statistically rejected at the 99.9% level independent of any physical theory.
