UN Warns Exceptional Extreme Temperatures Could Persist Worldwide Into 2027
————————————————————-
The United Nations has warned that exceptionally high temperatures are expected to continue into 2027, highlighting growing concerns over the intensification of extreme heat and its impact on populations around the world.

According to a UN News report published on November 9, 2026, the effects of extreme heat have already exposed millions of people to dangerous conditions. In April 2026 alone, approximately 146.5 million people in India experienced an extreme heatwave, with temperatures reaching 47 degrees Celsius.

The World Meteorological Organization (WMO), in its 2026 State of the Climate Update, warned that exceptional global temperatures, melting ice and rising sea levels are expected to persist, with a particularly strong El Niño potentially intensifying extreme weather events well into 2027.

The report highlighted the severe human impact of rising temperatures. In Europe, provisional estimates indicate more than 30,000 excess deaths during the summer, including approximately 16,000 during the heatwave of June 22–28. In India, around 146.5 million people were exposed to extreme heat in April, when temperatures reached 47°C. Nepal also suffered a catastrophic glacial collapse and subsequent flash floods in August, killing more than 1,300 people.
