by Glenn Spitzer, American Thinker:
Who are these “climate change deniers” we hear so much about? Does anyone really doubt the climate changes?
Well, yes. There are climate change deniers — a lot of them. They live right under our noses, and they are celebrated. Here’s a quote from one of the most famous climate change deniers:
Our civilization has never experienced any environmental shift remotely similar to this. Today’s climate pattern has existed throughout the entire history of human civilization.

That was Al Gore in 2007. According to Gore, the climate was “shiftless” for thousands of years — a paradigm of stability.
Gore’s quote was a restatement of Michael Mann’s 1998 “hockey stick.” Mann argued that the Earth’s climate held steady for all of human history (the hockey stick handle), until suddenly, in the 1900s, the temperatures increased, representing the upturned blade of the hockey stick.
Mann’s theory is the basis of the modern CO2-focused “global warming” movement, which ironically morphed into the “climate change” movement. Mann’s theory informs the positions taken by the Intergovernmental Panel on Climate Change (IPCC), the agency dictating policy to your local, state, and federal governments.
The most important assumption in Mann’s theory is that there was no climate change prior to the 20th century. But this assumption is false. It is climate change denial; it is the sacrifice of truth for a desired outcome.
Mann’s 1998 study intentionally ignored several thousand scientific publications showing other periods of climate change throughout human history, such as the Medieval Warm Period (about A.D. 900 to 1300), the Little Ice Age (about 1300 to 1915), and the Roman Warm Period (about A.D. 1 to 500). Despite claims of perpetual stability, it turns out the climate is always changing.
Scientists estimate that, during the Medieval Warm Period, for example, the temperatures in parts of Europe were 1.0–1.4° Celsius (1.8–2.5° Fahrenheit) warmer than they are now. Oxygen isotope studies in China, Germany, Greenland, Ireland, New Zealand, Switzerland, and Tibet, as well as tree ring data from many sites throughout the world, confirm the Medieval Warm Period. The studies are so numerous (several thousand published papers confirming this warming) that it raises the obvious question: “Why do climate activists deny that the climate is always changing?”
There are two important reasons why activists deny climate change. First, the acceptance of prior warming periods undermines the argument that a modern warming is an existential threat, and second, prior warming periods undermine the idea that anthropogenic (man-made) CO2 is the primary cause of climate change.
