M.Hillinger, comparing credentials is not a useful exercise according to you yet at the same time, apparently, you accept the global climate change data based, in part, on the credentials of those putting it forward. The sheer quantity of the data seems to convince you, yet those with equally sound credentials in the field are dismissed because they are in the minority. Since when has true science been about what the majority thinks? A person's credentials matter little if they are using flawed research design and skewed data as the basis of their outcomes. The history of science is filled with stories of the majority thinking being upended by one person following a different path from the "settled" science. We need dissent in science.
