This is a good example of the logical flaw known as "appealing to authority" ... chemists, geologists and the unidentified specialists are all experts in their fields, we have great confidence in their opinion within their area of expertise ... but that doesn't make them experts in climatology, or meteorology, or astronomy ...
Chemistry is at the heart of understanding the climate system
Rubbish ... very little chemistry happens in the atmosphere beyond the biology ... what sort of moron would say such a thing? ... oh, American Chemical Society, well ... okay ... morons, every one of them ... pffft, chemists, low grade science ...
