451,000 at risk: Where action can save lives during the Super El Niño

In this report scientists project that global land temperatures will be 1.2°C/2.1° F above normal in the coming months due in large part to the current “Super El Niño” that began in June and is expected to last through Northern Hemisphere spring. These anomalously warm conditions will resemble the higher temperatures that climate change is projected to deliver 20 years in the future (figure below) and will lead to 44% more extremely hot days than we would expect in a normal year. El Niño is effectively pushing us into the future – exposing us to temperatures that won’t be the norm for another two decades – before we have time to adapt and protect ourselves.

As a result, the researchers project that 451,000 lives will be lost due to heat in the first nine months (June-February) of El Niño, compared to a normal year. This is about 65 times larger than the 6,800 people believed to be dead or missing from the recent Nepal flash flood. In just the next 6 months, this includes 239,000 ± 11,000 deaths across the globe. With current forecasts suggesting El Niño will remain in place through spring 2027, we expect all of these numbers to grow even higher, particularly as impacts such as higher-than-average temperatures and heat-related deaths will linger into June and July.
