Why is "2020–21 North American winter" trending?

Wikipedia Overview

The 2020–21 North American winter was the most significant winter season to affect North America in several years, and the costliest on record, with a damage total of at least $33.35 billion. The season featured historic arctic blasts and multiple winter storms across much of the country. The Weather Prediction Center (WPC) tracked a total of 19 total significant winter storms, while six storms were ranked on the Regional Snowfall Index scale (RSI), four of which ranked as at least a Category 3. Most of the winter's damage and fatalities occurred due to a historic and major cold wave in mid-February. Several other significant events occurred, including a crippling early-season ice storm in the Southern Plains, a powerful nor'easter in mid-December, another major nor'easter in early February, two major and widespread winter storms in mid-February, and a major blizzard in the Rocky Mountains in mid-March. The winter-related events were responsible for at least 358 fatalities, making it the deadliest season since 1992–93. A La Niña pattern influenced much of the winter in North America.
