EDITORIAL: An inconvenient cooling

Reports of imminent climatic catastrophes are turning out to be rather anticlimactic. That’s because rather than heating up to life-threatening levels, new scientific findings indicate it’s more likely the Earth will cool in coming years. That’s bad news for a global-warming industry heavily invested in a sultry forecast. Cornelis de Jager, a solar physicist from the Netherlands and former secretary-general of the International Astronomical Union, announced that the sun is about to enter a period of extremely low sunspot activity, which historically is associated with cooling trends. Backed by other scientists, he predicted the “grand solar minimum” is expected to begin around 2020 and last until 2100. The ebb of solar activity is shaping up to resemble what occurred during the Little Ice Age, the period from 1620 to 1720 when sunspot activity diminished and temperatures dropped an estimated 3 degrees Celsius. The era was noted for colder-than-usual winters in North America and Europe, when rivers and canals froze over, allowing for ice-skating and winter festivals. It also resulted in crop failure and population displacement in northern regions such as Iceland. To characterize the impending grand solar minimum as an “ice age” - with glaciers forming at temperate latitudes - would be an exaggeration. The correlation between decreased sunspot activity and falling temperatures means it’s likely to get colder when the sunspots begin to disappear. Global-warming zealots are steamed. They’ve already cleverly rebranded their movement as “climate change” in order to appear relevant no matter what the thermometer reads, but the recent findings could undermine the basis for their cause...more
