“Greenhouse gases are the second most important factor for climate, after the Sun.” -Syukuro Manabe In 1967, a groundbreaking paper in climate science was published, detailing the inputs and feedbacks for the first accurate climate model. You don’t have to look far to find contentions that climate models are wrong, inaccurate and unreliable: 8 of…

“As an analogy one can imagine an intelligent amoeba with a good memory. As time progresses the amoeba is constantly splitting, each time the resulting amoebas having the same memories as the parent.

“If you haven’t found something strange during the day, it hasn’t been much of a day.” -John Archibald Wheeler Today, we take the existence of gravitational waves for granted.
