I like to think climate change is settled – we have scientific consensus, we know it’s happening, we generally understand the human actions that have accelerated climate change since the dawn of the industrial era. Many of us are feeling energy about reducing our carbon footprint and our overall planetary impact and concern that it’s too late for mitigation, time for adaptation. I personally have been involved with projects like Austin350, Worldchanging, and Powersmack, and I’ve blogged about global warming at Change.org. I’ve been thinking and writing about global warming since Bruce Sterling made me aware of it in the late 1990s. I worked with him on the Viridian Design Movement and wrote an article on climate change for the issue of Whole Earth Magazine he edited. In researching the article, “Being Green in 2001,” I learned that scientists were concerned that their commitment to scientific method – to hypotheses rather than certainties – was misinterpreted as uncertainty about the anthropogenic drivers of climate change. Since then broad scientific consensus has developed, especially via the UN’s Intergovernmental Panel on Climate Change, IPCC.
I was surprised, then, to have a conversation recently with an intelligent, articulate local businessman who told me that this scientific consensus doesn’t exist, and while he could acknowledge that the climate is changing, it’s a natural cycle associated with solar activity. He’s sent me various charts and links. He’s just forwarded an email that mentions Ian Plimer and his book Heaven and Earth, Bjorn Lomborg, and Kimberley Strassel’s Wall Street Journal op ed piece, “The Climate Change Climate Change,” which says that “the number of skeptics is swelling everywhere.” Among other things, she mentions a list that Senator Jim Inhofe has assembled of scientists who supposedly deny that human action is associated with global warming, and says that the earth’s temperature “has flatlined since 2001.” (Has it?) If you read the comments on the op-ed piece, you see that the question of human action and climate change has been politicized – challenged by the right as a left-wing scam. This is really unfortunate – the science is lost in a fog of political wrangling.
