Climate change, also known as global warming, is with 99.9% certainty man-made, a nonlinear physicist at McGill University concluded; in a paper published in Climate Dynamics.
In his paper tilted “Scaling fluctuation analysis and statistical hypothesis testing of anthropogenic warming,” Shaun Lovejoy can’t prove one negative — that humans aren’t ruining our planet. What he was able to do was demolish the claim that natural variability is the root cause of the world warming, not to mention extreme weather phenomena the world has recently 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 sought out to test whether the causes of climate changes are due to natural causes using statistics. His calculations are based not on computer models, but on actual findings in the field – of surface air temperatures – going back to the 16th century, way before industries began spewing clouds of carbon dioxide into the air.
Computer models forecasting the future draw back to historic data. Lovejoy looked at the temperature data collected for the models, and asked if nature could have caused it.
Lovejoy then calculated the probability of measured global warming from natural variability, based on the probabilities of natural fluctuations on a centennial scale. What did he conclude? The probability that Mother Nature caused this degree of global warming the planet has been experiencing since 1880 is less than 0.1%.
With that said, he has a 99.9 percent degree of confidence that the fluctuation of 0.9 of one degree in average temperature since 1880 is not natural. In other words, there is less than 1 in 100, he argues.
While he isn’t directly blaming humans for causing the mayhem, if it isn’t Mother Nature, we all known what else remains to blame.
