All those climate alarmists who proclaim that they “believe in science” fail to understand that science is created by flawed human beings who are susceptible to ignoring findings that don’t confirm their hypotheses.

In The Scientific American, which is all in on global warming as settled science, renowned science writer Sharon Begley chronicles the rediscovery “in a dusty basement” of a rigorous study from 40 years ago that contradicted the dietary wisdom of the day.
[Christopher] Ramsden, of the National Institutes of Health, unearthed raw data from a 40-year-old study, which challenges the dogma that eating vegetable fats instead of animal fats is good for the heart.
