It is due time for Al Gore and all other science ignoramuses to shut up. Science is not settled by popularity and politics. Today I see another example.
Each of these examples was settled fact for decades. No theory or computer model for global warming can even be validated when compared to the historical weather record.
Just as science book publishers are rewriting texts to say that there are eight planets instead of nine, they may have another edit to contend with - this time about the first inhabitants of the New World.
Since the 1960s, archaeologists have argued that the Americas were populated by one group of hunters that crossed a land bridge connecting Siberia to Alaska 11,500 years ago. The descendants of this population then moved throughout the hemisphere, taking up residence across North and South America.
But research published in this week's issue of the journal Science casts doubt on that scenario, supporting the long-standing arguments of David Overstreet, an archaeologist at Marquette University and the College of Menominee Nation, and Daniel Joyce of the Kenosha Public Museum.
For decades, these two scientists have shouted from the fringes of academia that the Clovis First theory was flawed. They pointed to sites across Wisconsin - Schaefer, Hebior and Fabry Creek - that showed that people were here before Clovis.
The science of climate change is not settled.
