Este assunto já me cansou há muito, mas continua "vivinho da silva"

Esta história é sintomática de mais de uma coisa - leiam, e cheguem às vossas conclusões. Começa assim:

"Climate models, and the predictions they make, are based on physics. We know how much more energy is trapped on Earth when we increase the greenhouse effect, and we have a good idea how much this trapped heat will warm the planet. We’ve understood these physical scientific concepts for over 150 years.

When climate contrarians make their own predictions, they tend to throw physics out the window. For example, as documented in my book and a paper I recently published with Rasmus Benestad and colleagues, contrarians have made climate predictions based on things like the orbital cycles of Jupiter and Saturnocean cycles and sunspots, and “natural fluctuations,” but they often completely disregard the basic, long-understood physics of the increasing greenhouse effect.

And so we have the latest such unphysical climate prediction, made in a report by Loughborough University statistics professor Terence Mills, on behalf of the anti-climate policy advocacy group, the Global Warming Policy Foundation (GWPF). The report essentially fits a statistical model to past global and local surface temperature changes, and then uses that statistical model to forecast future temperature changes. It’s an approach that’s been used to predict financial market changes, for example. ...."

GWPF throws out centuries of physics, climate scientists laugh, conservative media fawns
