About Us tab

We are the most qualified real climatologists to ever come out as global warming skeptics, including even more than Dr. Richard Lindzen, Dr. Judith Curry, and Dr. Roy Spencer, although we acknowledge their courage. We only came out after President Trump was elected because before that it would have been futile.

Unlike most scientists "counted" in the scientific consensus on global warming we are real climate scientists. Our graduate careers included numerous courses in climate and we have done extensive research in climate, including climate modeling and climate proxies (past climates). Doing both is unusual. Not only have we actually used and run climate models but we have actually programmed them and so fully understand their (huge) weaknesses. Unlike many we don't just ignorantly use the climate proxy data produced by others but we have taken courses and done research on climate proxies and so fully understand their (huge) weaknesses.

For those, mostly non-scientists, who are foolish enough to believe (and espouse) that peer review means that what is written is true, every word one of us writes is actually read by the other before publication. Scientists today often don't have time to even scan the current literature, never mind carefully read papers for peer review. Often a peer reviewer simply looks at the reputations of, or if he is friends with, the paper's authors to decide on whether the paper should be published. This is especially true for scientists who are non-native English speakers since English is the language of science and reading English carefully is a tedious task.

We do NOT get paid by the oil companies or anyone else to question global warming. We are not disgruntled employees trying to get back at our bosses. We just think climate science is one of the most fascinating sciences there is and to turn it into a lie for career advancement and political purposes is unconscionable.

No, we are no longer "working" climate scientists, which has been spuriously used to attack our credibility. After many years we became so disgusted at what climate science had been turned into that we quit. Just another example of the unqualified driving out the qualified until all that are left are unqualified but working climate scientists. In any case, we think we can do more good for climate science now by reforming it from outside, starting with cutting its funding.

I (Dr. Duane Thresher) started my own IT consulting (for VIPs) business, Apscitu. The same characteristics that made me, in the absolute sense, an excellent climate scientist -- being very qualified and insistent on doing things right -- make me an excellent IT consultant. There is however also a plague of incompetence to be fought in IT.

Rejected after standard sloppy peer review: I requested three specific less-biased reviewers, got three very-biased reviewers instead (careers dependent on established method), only two responded, one against, one neutral, and the editor cast the deciding vote against, not even being qualified to review the paper.

Herzschuh, U., H. Birks, L. Xingqi, C. Kubatzki, G. Lohmann, 2010: "Retraction: What caused the mid-Holocene forest decline on the eastern Tibet-Qinghai Plateau?", Global Ecology and Biogeography, 20(2), 366. After at least 4 rejections and deciding the paper had no scientific value worth publishing, and quitting working for Gerrit Lohmann at the Alfred Wegener Institute (AWI) due to his abusive behavior, I was horrified to discover 3 years after I quit climate science that the paper had been published with my name on it. As determined by the publisher lawyer, during a standard sloppy peer review Lohmann fabricated my required submission signature, the required revisions on my part of the paper (of which he had no expertise, making the paper scientifically invalid), and my responses to the peer reviewers. After harassment by Lohmann, aided by the journal (particularly chief editor David Currie of the University of Ottowa), of me, my husband, my current and former bosses, and my husband's current boss, I was finally able to get the paper retracted. Fraudulently, Lohmann and John Birks (University of Bergen) continued to list this paper in their publications without the required "Retraction" in the title.
