Stephens: Does Environmentalism Cause Amnesia ? Climate-change alarmists warn us about coming food shortages. They said the same in 1968.
Warming is becoming a major problem. "A change in our climate," writes one deservedly famous American naturalist, "is taking place very sensibly." Snowfall, he notes, has become "less frequent and less deep." Rivers that once "seldom failed to freeze over in the course of the winter, scarcely ever do so now."
From "Notes on the State of Virginia" by Thomas Jefferson, published in 1785.
