Islamabad (The COW News Digital) Climate experts have warned that a powerful Super El Niño could lead to nearly 900,000 additional heat-related deaths worldwide over the next 10 months, raising concerns about the potentially devastating consequences of extreme temperatures.
According to estimates from the Climate Impact Lab at the University of Chicago, approximately 484,500 excess deaths linked to extreme heat were projected between June and September this year. A further 372,900 fatalities could occur over the following six months, bringing the estimated total close to 900,000.
The projections highlight the growing risks associated with rising global temperatures and the possible intensification of heatwaves under a Super El Niño climate pattern.
Nigeria, India and Indonesia are among the countries expected to face particularly severe consequences. Nigeria could record more than 56,000 additional deaths, while India is projected to experience approximately 55,000 fatalities. Indonesia could see nearly 29,000 additional deaths, according to the estimates.
The figures reflect the anticipated impact of extreme heat on populations across different regions, with countries facing varying levels of exposure, vulnerability and preparedness.
Experts have also warned that China, Nigeria and India could collectively account for more than one-third of the expected deaths associated with El Niño-related heat.
The projections underline the significant health challenges that extreme temperatures can create, particularly in densely populated countries where millions of people may be exposed to prolonged periods of intense heat.
El Niño is a natural climate phenomenon associated with changes in ocean temperatures in the Pacific Ocean. It can influence weather patterns around the world, contributing to higher temperatures and shifts in rainfall.
A particularly strong event, commonly described as a Super El Niño, could intensify these effects and increase the likelihood of extreme heat in several regions.
Heat exposure can have serious consequences for human health. Prolonged high temperatures may contribute to dehydration, heat exhaustion and heatstroke. They can also place additional strain on the cardiovascular and respiratory systems, particularly among vulnerable individuals.
Older people, children, outdoor workers and those with existing health conditions may face heightened risks during severe heatwaves.
The anticipated impact could also place additional pressure on healthcare services, especially in areas where access to cooling facilities, medical treatment and reliable infrastructure remains limited.
The projected death toll has renewed attention on the importance of heat preparedness and public health protection.
Measures such as early-warning systems, public awareness campaigns, access to drinking water, shaded public spaces and cooling centres can help reduce the risks associated with extreme temperatures.
Authorities may also need to consider measures to protect outdoor workers and vulnerable communities during periods of intense heat.
Although the estimates indicate a potentially severe global impact, the actual number of fatalities will depend on the intensity and duration of heat events, local weather conditions and the effectiveness of preventive measures.
The projections should therefore be understood as estimates rather than confirmed future deaths.
The warning comes amid increasing international concern about the health consequences of climate change and the growing frequency of extreme weather events.
If the anticipated conditions materialise, the coming months could present a major public health challenge for countries across the world.
The latest estimates serve as a reminder that extreme heat is not merely a weather issue but a serious health threat requiring coordinated action from governments, healthcare authorities and communities.
