California Just Had Its Warmest Winter on Record

This winter has been a tale of two Americas: The Midwest is just beginning to thaw out from a battery of epic cold snaps, while Californians might feel that they pretty much skipped winter altogether. In fact, new NOAA data reveal that California’s winter (December through February) was the warmest in the 119-year record, 4.4 degrees Fahrenheit above the 20th century average.

The map above ranks every state’s winter temperature average relative to its own historical record low (in other words, relative to itself and not to other states). Low numbers indicate that the state was unusually cold; higher numbers mean it was exceptionally warm. As you can see, the Midwest was much colder than average, while the West was hotter than average (despite a season-long kerfluffle about polar vortexes, the East Coast wasn’t exceptionally cold, after all).

As we’ve reported, there’s currently a scientific debate over whether climate change in the Arcitc is making the jet stream “drunk,” and thereby increasing the likelihood of extreme cold spells; the exact role of climate change in California’s record heat is still unclear.

As anyone working in California’s farming industry could confirm, the state also had an exceptionally dry winter, the third-lowest precipitation on record. Other interesting facts from the NOAA report:

  • At the beginning of March, 91 percent of the Great Lakes remained frozen, the second-largest ice cover since record keeping began in 1973.
  • With reservoirs in central and northern California at 36 to 74 percent of their historical average levels, these regions would need 18 inches of rain over the next three months to end the drought, much more than the state normally gets in that time period.
  • Alaska’s winter was the eighth-warmest on record, 6.2 degrees F over the 1971-2000 average.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
