The writer seems to posit that a poll of scientists suffices to determine scientific veracity. I was just in a discussion with theology students and a prof who pointed out that science has been polluted philosophically.
For instance, one student critiqued findings from archeological studies showing that presuppositions many times replace valid proofs. Case in point was a study done of ancient cultures that found animal bone fragments and charcoal within city gates resulting in a conclusion that the society had engaged in animal sacrifice. Apparently no thought had been given to the idea that they had merely stumbled upon an ancient kitchen.
In many cases polled scientists will willingly defend positions outside their area of expertise. I attended a debate pitting young earth creation against evolution many years ago where the evolutionary position was supported by a geology professor and a zoology professor. The geology professor very honestly admitted that he could develop and live with young earth models, but he doesn’t because of his acceptance of conclusions from the biology scientists.
I think a lot of “scientists” who support anthropogenic global warming fit into this camp.
The implication in the article that the earth has been warming is itself subject to interpretation given the recent admission by the U.K. Office of the Met that there has been no discernible warming for the last 16 years.
My experience with scientists in college was that they staked out a position, got tenure and then spent the rest of their lives defending their original position no matter what the facts said.
