Climate change isn’t causing the multi-year drought that is devastating parts of Argentina, Uruguay, Brazil and Bolivia, but warming is worsening some of the dry spell’s impacts, a new study says.
The natural three-year climate condition La Nina – a cooling of the central Pacific that changes weather worldwide temporarily but lasted much longer than normal this time – is the chief culprit in a drought that has devastated central South America and is still going on, according to a flash study released Thursday by international scientists at World Weather Attribution. The study has not been peer reviewed yet.
