Climate ‘teleconnections’ may link droughts and fires across continents
Large-scale climate patterns that can impact weather across thousands of kilometers may have a hand in synchronizing multicontinental droughts and stoking wildfires around the world, two new studies find.
These profound patterns, known as climate teleconnections, typically occur as recurring phases that can last from weeks to years. “They are a kind of complex butterfly effect, in that things that are occurring in one place have many derivatives very far away,” says Sergio de Miguel, an ecosystem scientist at Spain’s University of Lleida and the Joint Research Unit CTFC-Agrotecnio in Solsona, Spain.
