Science votes for human-caused global warming in a landslide

climate-change-consensusI don’t discuss anthropogenic global warming (AGW, or climate change caused by human activities) very often, more just in oft-handed ways, lumping anthropogenic global warming deniers into the whole pseudoscience crowd–antivaccinationists, anti-GMO loudmouths, evolution deniers, HIV/AIDS deniers, and other anti-science fads. To be honest, I was scientifically skeptical about global warming, not because of any political motivation, but because the evidence I reviewed seemed weak at best. But I was guilty of my own confirmation bias, and more than that, I was honestly more interested in other current trends in science than climate change. 

Now, I was never a skeptic (kind of improperly used in my case, I really thought I had examined it scientifically) about global warming itself. I observed changes over my long lifetime, including one year in the early 1980’s when ski resorts in Utah were open well into July. And the Great Salt Lake was heading to levels not seen since the ice age. When I was in grad school in New York, it snowed on July 4th. This doesn’t happen much anymore (and it really isn’t evidence of global warming, but it’s always good when my personal anecdotes are supported by good science). Moreover, the real science, the real numbers, showed that the earth was warming up. Continue reading “Science votes for human-caused global warming in a landslide”
