Climate, Water, Carbon Dioxide, and the Sun

From a societal point of view, the climate dispute involves not one but two agendas: environment and climate. The environmental agenda (pollution, waste, clean water and air, health issues) is clearly to be applauded, as is the political agenda of diversification of energy sources.

The relevance of the climate agenda (mitigation and/or adaptation), however, depends on the outcome of an as-yet open scientific debate, because carbon dioxide by itself is not a pollutant, but is in fact the basis of our food chain and thus of all life.
