Climate Signals Summary: There are three things to consider when squaring this extreme winter weather with climate change: cold weather doesn’t cancel out decades of warming; rapid Arctic warming is associated with disruptive winter weather in the US; and cold events aren’t as cold as they would have been without climate change.
A prolonged, historic arctic cold outbreak will hang on for a bit longer in parts of the South before a more pronounced warmup brings relief to those shivering and without power in Texas, Oklahoma and other parts of the Plains.
The double whammy of record-smashing cold and one of the heaviest snowstorms parts of the South have seen in decades has taken its toll.
Blackouts left millions of homes and businesses without electricity, some even without running water.
