A study by a former skeptic of global warming — and funded in part by the Koch Brothers — has confirmed that human activity is likely causing the Earth to warm. Prof Richard Muller was once a critic of global warming but now says the evidence is clear in establishing the connection to human activity.
Muller leads the Berkeley Earth Project and assembled an impressive array of scientists to use new methods and some new data to investigate the global warming theory. The study reached the same conclusion of earlier studies.
The Koch brothers were not the only funders who have historically opposed global warming theories, but the scientists still concluded that the data speaks of itself. Muller wrote: “Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.”
