In this report, we review the long-term climate history of the United States and find little in the way of evidence that the on-going atmospheric build-up of greenhouse gases (“global warming”) has acted to alter the country’s general climate state. Moreover, what climate changes have occurred over the past century or so have largely been benign (or even positive), have been adapted to, or both.
