Physics professor Richard A. Muller now believes that the world's climate change is a result of human activity.
Muller, once one of the most noted scientists who continued to deny the fact that global warming even existed, now says that it does and he says we are to blame.
In a New York Times editorial, 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."
Muller is employed by UC Berkeley, which recently received considerable funding from the Charles Koch Charitable Foundation, which happens to give a lot of money to global warming skeptics.
The LA Times quoted Koch Foundation spokesperson Tonya Mullins as saying, "Our grants are designed to promote independent research; as such, recipients hold full control over their findings. In this support, we strive to benefit society by promoting discovery and informing public policy."
The biggest cohesive group of manmade global warming skeptics continues to be meteorologists, who see the admitted increase in global temperature and changes to the climate as being nothing more than the expected cyclical planetary change.
After all, there were things like ice ages and ice melt long before anyone started burning coal, and this is what many meteorologists point to when they try to debunk the manmade theory.
But, Muller writes, "Earth’s land has risen by two and a half degrees Fahrenheit over the past 250 years, including an increase of one and a half degrees over the most recent 50 years. Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases."
