Unlike Modern Climate Change, the Biggest Swings in Recorded History Were Just Regional Patterns

Today’s climate change is unlike any seen in the last 2,000 years, scientists report Wednesday in the journal Nature. New research shows that the civilization-altering warm and cold periods of recent human history, like the so-called Little Ice Age, did not occur across the entire globe but instead happened in isolated regions. That’s in sharp contrast to our current era of worldwide warming.
