Climate science myth-buster Judith Curry: the climatology ‘policy cart is leading the scientific horse’

From Mark Perry.

"From the City Journal article “Climate Science’s Myth-Buster: It’s time to be scientific about global warming, says climatologist Judith Curry” by Guy Sorman, who interviews myth-buster Judith Curry:

Judith Curry is a scholar, not a pundit. Unlike many political and journalistic oracles, she never opines without proof. And she has data at her command. She tells me, for example, that between 1910 and 1940, the planet warmed during a climatic episode that resembles our own, down to the degree. The warming can’t be blamed on industry, she argues, because back then, most of the carbon-dioxide emissions from burning fossil fuels were small. In fact, Curry says, “almost half of the warming observed in the twentieth century came about in the first half of the century, before carbon-dioxide emissions became large.” Natural factors thus had to be the cause. None of the climate models used by scientists now working for the United Nations can explain this older trend. Nor can these models explain why the climate suddenly cooled between 1950 and 1970, giving rise to widespread warnings about the onset of a new ice age. According to a group of scientists, we faced an apocalyptic environmental scenario—but the opposite of the current one.

…..

This brings us to why Curry left the world of the academy and government-funded research. “Climatology has become a political party with totalitarian tendencies,” she charges. “If you don’t support the UN consensus on human-caused global warming, if you express the slightest skepticism, you are a ‘climate-change denier,’ a stooge of Donald Trump, a quasi-fascist who must be banned from the scientific community.” These days, the climatology mainstream accepts only data that reinforce its hypothesis that humanity is behind global warming. Those daring to take an interest in possible natural causes of climactic variation—such as solar shifts or the earth’s oscillations—aren’t well regarded in the scientific community, to put it mildly. The rhetoric of the alarmists, it’s worth noting, has increasingly moved from “global warming” to “climate change,” which can mean anything. That shift got its start back in 1992, when the UN widened its range of environmental concern to include every change that human activities might be causing in nature, casting a net so wide that few human actions could escape it.

Scientific research should be based on skepticism, on the constant reconsideration of accepted ideas. What could lead climate scientists to betray the very essence of their calling? The answer, Curry contends: “politics, money, and fame.” Scientists are human beings, with human motives; nowadays, public funding, scientific awards, and academic promotions go to the environmentally correct. Among climatologists, Curry explains, “a person must not like capitalism or industrial development too much and should favor world government, rather than nations”; think differently, and you’ll find yourself ostracized. “Climatology is becoming an increasingly dubious science, serving a political project,” she complains. In other words, “the policy cart is leading the scientific horse.”

Curry’s pragmatism may not win acclaim in environmentalist circles or among liberal pundits, though no one effectively contests the validity of her research or rebuts the data that she cites about an exceedingly complex reality. But then, neither reality nor complexity mobilizes passions as much as myths do, which is why Judith Curry’s work is so important today. She is a myth-buster."
