Is there a new scientific consensus forming around global cooling? That’s what environmentalist Lawrence Solomon writes in the Financial Post, citing the fact that solar activity is decreasing at the fastest rate as anytime in the last 10,000 years.

“Now an increasing number of scientists are swinging back to the thinking of the 1960s and 1970s,” Solomon writes. “The global cooling hypothesis may have been right after all, they say. Earth may be entering a new Little Ice Age.”

Solomon adds that Columbia University’s George Kukla — who warned the U.S. government about the dangers of global cooling in 1972 — postulated that “[g]lobal warming always precedes an ice age… The warming we saw in the 1980s and 1990s, in other words, was expected all along, much as the calm before the storm.”
