Recent studies have put the final nails into the coffin of natural warming theories. While Republicans and other conservatives hold on to natural warming theories the way NRA members cling to their guns, recent science has utterly dispelled the viability of this myth.
While it is impossible to refute the observation that the earth has warmed since 1880, it is not uncommon to hear Republicans say that while global temperatures may be warming, it is not attributable to human activity.
An April analysis published in the journal Climate Dynamics, reviews temperature data since 1500 and concludes that the global warming we have seen since the dawn of the industrial era cannot be attributed to natural warming.
This research was conducted by McGill University physics professor Shaun Lovejoy, and rules out the hypothesis that warming over the past century is due to natural fluctuations.
“This study will be a blow to any remaining climate-change deniers,” Lovejoy said. “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’s conclusions come with confidence levels that exceed 99 percent certainty. The odds of warming being caused by natural fluctuations are less than one in a thousand.
Lovejoy’s new study is based on statistical methodology that uses multi-proxy climate reconstructions as well as fluctuation-analysis techniques from nonlinear geophysics. Lovejoy’s findings effectively complement other studies including those that use computer modeling. His findings are also corroborated by the most recent International Panel on Climate Change (IPCC) reports and the Third US National Climate Assessment.
