A bit disingenuous as the magnitude of the problem is far from known. As I have stated previously, this is an area of ongoing research and is hardly settled science. The homogenization of certain observational datasets and the lack of fidelity in the treatments of certain physical processes in numerical models makes any conclusions suspect. Well respected scientists such as Lennart Bengtsson have expressed the opinion that we simply don't know the magnitude of anthropogenic warming nor the time scale. 40 years ago the concern was about global cooling. Full disclosure: undergraduate and graduate degrees in atmospheric science, researcher and numerical model developer for NASA and the National Weather Service.
