A study published in Nature Sustainability shows that exposure to extreme heat will significantly increase by 2050, especially affecting developing countries.

Scientists have published a study in the journal Nature Sustainability, highlighting the impact of global warming on exposure to extreme heat. Projections suggest that if global temperatures rise by 2°C compared to pre-industrial values, the number of people affected by extreme heat could nearly double by 2050, reaching 3.79 billion. The effects will be felt as early as this decade, as the threshold of 1.5°C approaches.

The lead author, Jesus Lizana, emphasizes that the need for adaptation is more urgent than previously estimated, requiring the construction of infrastructure such as sustainable cooling systems. The energy demand for cooling will increase drastically in developing countries like India and Bangladesh, which are facing severe health consequences.

Additionally, wealthy countries like Canada and Russia are not prepared for the anticipated heatwaves. These countries need to be aware of the risks and prepare for the increasing number of hot days. Radhika Khosla, a co-author of the study, emphasizes that the most disadvantaged will suffer the most from these climate changes.
