A distinguished atmospheric scientist in the field of radiative transfer and remote sensing feels he has to speak out about the hyperbole surrounding “certainty” in global-warming science:

The recent IPCC summary report has just informed me, and the rest of the world, that there is little doubt but that the global warming we are experienced is due to greenhouse gas emissions into our atmosphere. That conclusion was really surprising to me, it having come from a world wide group of supposedly outstanding climate experts.
