Super El Niño Threatens Record Heat Deaths in the Philippines

Global Death Toll Projected at 451,000 as Super El Niño Develops

The ongoing Super El Niño, which began in June, is developing at unprecedented speeds and is expected to persist through the Northern Hemisphere spring in 2027. According to University of Chicago researchers, the climate pattern will cause 451,000 excess deaths worldwide between June and February compared to a normal year. Of that total, 239,000 fatalities are projected to occur in the next six months. Researchers noted that this projected global death toll is about 65 times larger than the 6,800 people believed dead or missing from recent flash floods in Nepal.

Global land temperatures are forecast to average 1.2 degrees Celsius, or 2.1 degrees Fahrenheit, above normal in the coming months. Researchers describe these unusually warm conditions as a “postcard from the future” that mirrors the higher temperatures climate change is projected to deliver two decades from now. This anomaly will generate 44 percent more extremely hot days than a normal year.

Regional Impacts Across the Philippines and Southeast Asia

In the Philippines, researchers estimate the extreme heat will cause 6,500 additional heat-related deaths. The country ranks ninth out of 50 nations most affected by extreme heat during this climate event. Across Southeast Asia as a whole, the research projects an additional 19,400 heat-related deaths spanning the Philippines, Vietnam, Thailand, and Cambodia, while neighboring Indonesia faces another 19,300 deaths.

Other global regions will also bear a heavy burden. Countries across the Sahel region—including Nigeria, Sudan, Niger, and Chad—will see 66,800 extra heat deaths from September to February. India faces 15,800 additional deaths, and Brazil could record 13,300. Domestically, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) reported earlier that climate models indicate El Niño could intensify to a “very strong” level between September and December.

Mitigation Strategies and Adaptation Investments

To combat rising mortality rates, researchers emphasize that several solutions are already available. These include anticipatory financing, heat early warning systems, and action plans that enable health officials to identify vulnerable groups, conduct home visits, increase access to water, and monitor heat-related symptoms. Expanded water availability and wider access to cooling technologies are also critical.

“Mortality projections for the near term provide a signal of where we are headed if new adaptation investments do not materialize,” researchers stated. They noted that unlike long-term climate change, near-term El Niño impacts provide more immediate opportunities to undertake targeted adaptations and save lives.

Frequently Asked Questions

What is driving the high projected death toll during this El Niño?

The current Super El Niño is developing at record-setting speeds, pushing global land temperatures 1.2 degrees Celsius above normal and creating 44 percent more extremely hot days than usual.

Which regions are most affected by the extreme heat?

Countries in the Sahel, Southeast Asia—including the Philippines and Indonesia—as well as India and Brazil, are projected to experience the highest number of excess heat-related deaths.

What measures can governments take to prevent heat deaths?

Researchers recommend implementing heat early warning systems, anticipatory financing, targeted home visits for vulnerable populations, and increasing access to water and cooling technologies.
