"The voter rebellion is on solid scientific ground. The global expenditure to curb CO2 emissions, estimated in 2009 by Danish scientist Bjorn Lomborg to cost $180 billion a year, stems from the U.N.-engineered 1997 Kyoto Protocol. That treaty was always about politics, not science. In recent years global weather stations have measured ups and downs, but data from U.S. and British monitoring agencies showed that global temperatures in 2017 were roughly what they were 20 years earlier.
Climatology is mostly guesswork. There’s no way to conduct a controlled experiment to ascertain scientific validity. Climatologists have learned a lot about climate and weather in the past century, but actually controlling the climate is something else entirely.
In a lecture this year, Massachusetts Institute of Technology meteorologist Richard Lindzen posited two immense, complex and turbulent fluids—the oceans and the air in the atmosphere—are in constant reaction with each other and the land, causing what we experience as storms and temperature changes. Variations in the sun’s radiation and the rotation of the planet play parts as well. And yet, he said, climate modelers claim that only one tiny component of this enormous churning mass, CO2, controls the planet’s climate.
This borders on “magical thinking,” he said, and yet it is a narrative that has been widely accepted. The story begins with Maurice Strong, a Canadian oil tycoon who believed the Club of Rome’s doomsday forecast in 1972 that a rising global population would soon exhaust the planet’s resources. Strong persuaded the U.N. to put him in charge of an environmental program to save the planet.
In the 1980s, the Reagan State Department, seeking to get more science into the climate debate, prodded the U.N. to create the Intergovernmental Panel on Climate Change. Its mission was to assemble scientists and assess whether mankind was having an effect on climate. The first assessment, in 1990, could find no “signal” of such an effect. Neither could the second assessment, in 1995. But the U.N. issued a separate “report to policy makers” saying essentially the opposite—human activity is making the climate hotter.
Frederick Seitz—a pioneer in solid-state physics, former president of the National Academy of Sciences and recipient of the National Medal of Science—was furious. He wrote an op-ed for the Journal in June 1996 alleging the report had been edited after being peer reviewed “to deceive policy makers and the public into believing that the scientific evidence shows human activities are causing global warming.” He and some colleagues circulated a petition to Congress with their complaint and ultimately received the signatures of more than 32,000 scientists and engineers."
