_Climate Ideology Ignores Science, Threatens Humanity_

FTA: Climate scientists would be less likely to issue dire warnings of planetary doom if they gave more credence to the geological history of the past several million years. Instead, they rely on computer models that are biased by the preconceptions of their manipulators and incapable of accounting for the myriad factors influencing global temperatures.

Minuscule recent warming, whatever the cause, is inconsequential in light of the long record of data found in Antarctica ice cores that go back 800,000 years. The bottom line is that Earth is colder by nearly 3 degrees Celsius than it was 3,000 years ago and is just now climbing out of its longest cold spell of the last 10,000 years. Blaring headlines about record heat waves of the past 100 years are meaningless, hysterical blather.

A deeper dive into geologic history — based partly on the record stored over millions of years in deep-ocean sediments — shows that today’s carbon dioxide concentrations of 420 parts per million are a fraction of past levels that reached 5,000 ppm and more. Carbon dioxide is nearly at its lowest level ever since plant life began so many millions of years ago and well below the optimum amount for the health of most vegetation.

In fact, the 280-ppm concentration of the mid-19th century is uncomfortably close to the point at which plant life dies — below 150 ppm. Given that all life depends on adequate amounts of this gas, proposals to reduce atmospheric carbon dioxide are nothing less than reckless.
