Winter has arrived much earlier than normal this year, particularly across North America, where cold records have been shattered. This Thanksgiving is in fact going down as one of the coldest ever on record across the Northeast.

The Washington Post here, for example, reports that “Thanksgiving and Black Friday 2018 will be remembered for a record-shattering cold snap across the Northeast United States.”

Also WeatherNation tweeted some impressive record low temperatures being set:

Records for November 22 were set in Canada across Ontario as well. […]

Solar activity lowest level in near 200 years

So what could be behind all the surprising record-setting cold and early wintry weather?

huge volume of scientific literature suggests that low solar activity is playing a major role. The 20th century saw especially strong solar activity, but it has quieted down substantially since the mid 2000s.

The last solar cycle (no. 24) is now all but officially the weakest in close to 200 years, since Solar Cycle 6.
