CO2 and other greenhouse gases (GHG) such as methane have been suspected for more than a century of being potentially harmful atmospheric warming agents. The climate movement began more recently with the advent of the U.N. Intergovernmental Panel on Climate Change (IPCC) in 1989 and the release of Al Gore’s prize-winning film An Inconvenient Truth in 2006. Climate alarm began as “man-made global warming” and, when cooling was observed even as CO2 levels continued to rise, morphed into “climate change.”
Those of us who can look behind the virtue-signaling mantra of climate change understand the theory that man-made carbon dioxide (CO2) emissions from burning oil and gas are dangerously warming the planet. We can also appreciate the idea that marginal warming may be amplified by increased water vapor and clouds as a result of elevated CO2. A large number of computer models are built on the presumptions of this theory.
