Earth’s weather is shaped by several natural climate phenomena. Among them, El Nino is turning out to be a record-breaking beast this year, releasing extraordinary amounts of heat from the ocean and fuelling droughts, floods and severe storms. By September, the climate pattern had already raised the temperature in the central and eastern equatorial Pacific Ocean by 3.08 degrees, more than any other El Nino ever recorded. Some experts are already calling it a “Super El Nino”, and now a map from the Climate Impact Lab shows where it will cause the most additional heat-related deaths.

Called El Nino Heat Mortality Tracker, more than 373,000 additional people will perish in the next six months.

“Being able to anticipate the deadly effects of extreme heat is a major step forward. It means we can identify where people face the greatest risks and give decision-makers a chance to act before lives are lost. The Tracker provides this information for the Super El Nino we’re living through today,” said Michael Greenstone, a co-founder of the Climate Impact Lab.

The grim forecast says El Nino’s heat deaths will be concentrated overwhelmingly in the Global South. India is expected to experience the highest toll between October and March with about 55,000 heat-related deaths projected, the mortality tracker claims. Most of these deaths will take place in March.
