The 3% of Climate Change-Papers which call Climate Change Bullshit are Bullshit

Schöne Meta-Studie im „journal of Theoretical and Applied Climatology“: Learning from mistakes in climate research. Die haben sich eine Auswahl der 3% der Klima-Papers angeschaut, deren Ergebnisse vom Konsens den mensch-verursachten Klimawandels abweichen – und konnten keins der Ergebnisse replizieren und haben in allen Papers fehlerhafte Resultate festgestellt. Tja.

Quartz: Those 3% of scientific papers that deny climate change? A review found them all flawed

Katharine Hayhoe, an atmospheric scientist at Texas Tech University, worked with a team of researchers to look at the 38 papers published in peer-reviewed journals in the last decade that denied anthropogenic global warming. “Every single one of those analyses had an error—in their assumptions, methodology, or analysis—that, when corrected, brought their results into line with the scientific consensus,” Hayhoe wrote in a Facebook post.

One of Hayhoe’s co-authors, Rasmus Benestad, an atmospheric scientist at the Norwegian Meteorological Institute, built the program using the computer language R—which conveniently works on all computer platforms—to replicate each of the papers’ results and to try to understand how they reached their conclusions. Benestad’s program found that none of the papers had results that were replicable, at least not with generally accepted science.

Broadly, there were three main errors in the papers denying climate change. Many had cherry-picked the results that conveniently supported their conclusion, while ignoring other context or records. Then there were some that applied inappropriate “curve-fitting”—in which they would step farther and farther away from data until the points matched the curve of their choosing. And of course, sometimes the papers just ignored physics altogether. “In many cases, shortcomings are due to insufficient model evaluation, leading to results that are not universally valid but rather are an artifact of a particular experimental setup,” the authors write.
