An Inconvenient and Belated Truth

I post about global warming on occasion here because foreigners like to beat us about the head and shoulders for our failure to cripple our economy in order to fix what science has deemed a crisis.

I'm just not impressed with how the scientists involved are acting. Their thin skin makes it seem like they aren't too interested in defending their science or policy recommendations.

And science is not the infallible measure that the global warmers liket to pretend it is.

Case in point is the debate over the first Americans. Twenty years ago, at a previous job, I talked with a colleague who was in graduate school for archaeolgoy. He was amazed that the evidence that called into the whole Clovis theory into question was simply ignored. Anybody who tried to question that theory by bringing up evidence of prior settlements had no future in the profession. My friend told me there were sites that predated Clovis but his profession wouldn't deal with them.

Questioning Clovis was heresy. That was the state of the science then.

Well, Clovis is finally being questioned:


Using advanced radiocarbon dating techniques, researchers writing in the journal Science on Thursday said the Clovis people, hunters of large Ice Age animals like mammoths and mastodons, dated from about 13,100 to 12,900 years ago.

That would make the Clovis culture, known from artifacts discovered at various sites including the town of Clovis, New Mexico, both younger and shorter-lived than previously thought. Previous estimates had dated the culture to about 13,600 years ago.

These people long had been seen as the first humans in the New World, but the new dates suggest their culture thrived at about the same time or after others also in the Americas.

Michael Waters, director of Texas A&M University's Center for the Study of the First Americans, called the research the final nail in the coffin of the so-called "Clovis first" theory of human origins in the New World.

Waters said he thinks the first people probably arrived in the Americas between 15,000 and 25,000 years ago.

Scientists are not immune to bias. And this example is over a topic few people really worry about. Imagine how bias can insinuate itself when the scientists are straying from the pure science and advocating policy?

I wonder what the state of global warming science will be in twenty years?

Back to my regular programming.
