A stunning map shows how soaring temperatures are affecting people around the world – 48 hours after the world recorded its hottest day on record.
Using June as a snapshot, the infographic highlights just a few of the regions hit by intense heat – including the UK, which has not escaped the rising temperatures.
In China, several cities set new records as the temperature topped 40C, while in Spain mercury temperatures hit 44C – after hitting nearly 40C during a spring heatwave in April.
The heat had severe consequences in a number of countries, including India, where unseasonably high temperatures killed more than 160 people in the northern states of Uttar Pradesh and Bihar.
In neighboring Pakistan, at least 22 people died during a severe heatwave, while in Mexico, more than 110 people have died from heat-related causes so far in 2023.
Heat-related deaths occur every year. A 20-year study published in 2021 found that extreme temperatures — both hot and cold — kill more than 5 million people worldwide each year.
The study found that more people died from cold than from heat, but over the study period, heat-related deaths increased while cold-related deaths decreased.
Researchers collected data from 750 sites in 43 countries between 2000 and 2019 and found that the average daily temperature rose by 0.26°C per decade.
On Monday, the US National Centers for Environmental Prediction reported that the world had experienced its hottest day on record, with an average global temperature of 17.01C. The previous record was 16.92 °C and was set in August 2016.
Scientists believe a strengthening El Niño event, which normally warms the world, combined with human-caused climate change due to greenhouse gas emissions is responsible for the rise in temperature.
