Are we facing a dangerous period of global cooling? That’s not a question that many have been asking. But reports that there has been a sharp reduction in sunspot activity raises that possibility. It has happened before. In his book Global Crisis: War, Climate Change & Catastrophe in the Seventeenth Century, historian Geoffrey Parker writes:
“The development of telescopes as astronomical instruments after 1609 enabled observers to track the number of sunspots with unprecedented accuracy. They noted a ‘maximum’ between 1612 and 1614, followed by a ‘minimum’ with virtually no spots in 1617 and 1618, and markedly weaker maxima in 1625-26 and 1637-9. And then, although astronomers around the world made observations on over 8,000 days between 1645 and 1715, they saw virtually no sunspots: The grand total of sunspots observed in those 70 years scarcely reached 100, fewer than currently [the book was published in 2013] appear in a single year. This striking evidence of absence suggests a reduction in solar energy received on earth.”
The result of the “Maunder Minimum” of sunspots was a so-called Little Ice Age, with significantly colder temperatures in the temperate zones, low crop yields to the point of famine and, Parker writes, “a greater frequency of severe weather events—such as flash floods, freak storms, prolonged drought and abnormal (as well as abnormally long) cold spells.”
Global warming alarmists have been claiming for decade that increases in carbon dioxide emissions associated with human activity will produce disastrous climate events. Certainly if carbon dioxide emissions were the only factor affecting climate, increases in those emissions would indeed produce global warming. Inconveniently for this theory, world temperatures have not increased in the last 15 years. But surely there are other things that affect climate, including variations in solar activity—sunspots. And as Bjorn Lomberg has often written, global cooling would be much more dangerous to human beings than global warming. Parker’s 697-page book (no, I haven’t read the whole thing) is an account of the political and demographic disasters in a global cooling century. Something to think about the next time you hear warnings of the inevitable disasters coming thanks to global warming.
