Ethan Siegel in Forbes magazine declared “There’s no science behind denying climate change“. Siegel describes the scientific method and its application to climate science and concludes that “every scrupulous, competent scientist that investigates it has come to the same conclusion: it’s real, it’s warming, and it’s our CO2 that’s doing it. You are free to deny climate change if you want, but there’s no scientific leg to stand on if you do.”
There is plenty of data to support this conclusion.
There are still scientific disagreements over questions of “how much,” “how fast,” and “in what ways will the climate change in various locations,” but there is no scientific doubt over the overall conclusions.
