Unsettled Science

We are told by government-funded climate alarmists that their forecasts of dangerous man-made global warming rely on “settled science”. Their “settled science” represents a mare’s nest of computer models, resting on a few match-sticks of science, surrounded by tall forests of uncertainty. It is indeed settled science that all gases in the atmosphere can affect the exchange of heat between the sun, the Earth and outer space, and this can affect global temperatures. It is also agreed that certain gases like water vapor and carbon dioxide can absorb and redirect radiant energy passing through the atmosphere. It is also settled science (but seldom mentioned) that the warming potential of each additional unit of carbon dioxide is progressively less, and is trivial at and above current levels. It is also agreed that water vapour has a far greater “greenhouse effect”, because it is fifty times more abundant, and it affects more radiation...(Read Full Post)
