Last month, Attorney General Loretta Lynch testified before the Senate that the Department of Justice that she is considering taking legal action against energy industries dubious of the dire role of carbon emissions to change the climate. And Democratic attorneys general from numerous states are in hot pursuit of global warming heretics.
Before more partisan lawyering and congressional testimony clouds the climate change concern, let’s clear up what is known about this issue.
“Everything we know about the world’s climate — past, present, and future — we know through models.” So states professor Paul Edwards, a supporter of the “consensus” view of climate change, in the Introduction to his highly acclaimed book A Vast Machine: Computer Models, Climate Data, and the Politics of Global Warming (MIT Press, 2010). He also notes that “without models, there are no data.” [italics in original]
Models have become integral to modern scientific practice. In many fields, Edwards says “computer models complement or even replace laboratory experiments; analysis and simulation models have become principal means of data collection, prediction, and decision making.”
Such is the contemporary world of science aided by the powerful tool of modern computers. The three basic components of the scientific method — observation, hypothesis, and testing — still hold, but in many cases the testing portion has been abetted, if not in some cases usurped, by models.
As many challengers of the manmade disastrous global warming hypothesis can attest, the “evidence” for a worldwide climate catastrophe is founded upon the results of atmospheric models. Yet, can such results be trusted enough to direct trillions of dollars in the years ahead to shift the energy sector and redistribute financial resources? After all, as University of Pittsburgh virologist John Mellors asserted in a recent article about HIV treatment in Science (“Researchers claim to find HIV sanctuaries,” January 29, 2016), “You can use a model to support anything you want, but you can prove nothing… You can model that the sun orbits the Earth.”
Atmospheric models have tremendous difficulty simulating key elements of the hydrologic cycle like cloud cover and precipitation patterns. Such components are obviously important to decades-hence projections heavily relied upon for drastic global public policy decisions.
