It's a perfectly normal mistake for a lay person and it's common in the wingnut press, but I certainly didn't expect to hear it at an AGU meeting. (The surface temperature of Venus makes an excellent counterargument if you don't actually want to work through the math.) So I turned around expecting to see a young beginner and set him straight, only to find myself staring at Dr Ball's nametag, so I saved my breath.
Keep his ability to get things totally wrong in mind as you read his history of the IPCC. See, in the alternate universe from which Dr Ball hails, the evidence for anthropogenic climate change gets weaker and weaker every year. Yet another transporter beam accident?
Note the concluding paragraph:
As evidence grew that the hypothesis was scientifically unsupportable adherents began defending rather than accepting and adjusting. The trail they made is marked by the search for a clear human signal, identified in modern parlance as ‘smoking guns.’ They also became trapped in what Russian writer and philosopher Leo Tolstoi identified many years ago, namely, “I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives.” Next we will examine how the political system that Strong and the UN set up allowed perpetuation of incorrect science and falsely identified smoking guns.As evidence "grew" ???
