Together, these effects may have helped trigger a rare three-year La Ni\u00f1a from late 2019 to 2022. The effects of La Ni\u00f1a spread across the globe, intensifying drought and famine in East Africa and preparing the Atlantic Ocean for hurricanes. 2020 became the most active tropical storm season on record with 31 tropical and subtropical systems including 11 storms making landfall in the US, including four isolated in Louisiana. <em>(Bob Berwyn, Incise Climate News)<\/em><\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>New research implicates emissions from the 2019-2020 Australian fires in the emergence of a three-year Super La Ni\u00f1a that fueled droughts in Africa and hurricanes in the Atlantic.
