New Muller quote: "In the end, a really good match came to the greenhouse gases. That came as a surprise to me, because I'd really thought that the ocean currents and the variability of the sun would dominate, but it wasn't the case. It was purely greenhouse gases. At that point, my conclusion was not only is global warming real, but essentially all of it is caused by humans"

UC Berkeley Physics Professor and energy consultant Richard Muller's new study finds that climate change is real and caused by humans. Muller gained notoriety for previously stating that there was not enough evidence to come to that conclusion. (Aug. 1)

Muller, just past the 1:00 mark: "[we looked for] fingerprints, if you like, of volcanoes, of solar variability, of ocean currents, of greenhouse gases. To our shock, the volcanic eruptions were all very short-lived, so they had an effect, but only for a few years. The long-term trend, there was no component of that due to the solar variability. In the end, a really good match came to the greenhouse gases. That came as a surprise to me, because I'd really thought that the ocean currents and the variability of the sun would dominate, but it wasn't the case. It was purely greenhouse gases. At that point, my conclusion was not only is global warming real, but essentially all of it is caused by humans".
