Scientific study: the frequency and intensity of extreme temperature fluctuations are increasing significantly

A recent scientific study conducted by researchers from Nanjing University and the Institute of Atmospheric Physics of the Chinese Academy of Sciences concludes that the frequency and intensity of extreme temperature fluctuations are increasing markedly, posing a direct threat to global public health.

The study explains that these fluctuations are becoming more frequent and more extreme in low- and mid-latitude regions, mainly due to greenhouse gas emissions resulting from human activities.

Climate projections indicate a worsening trend, with the frequency of extreme temperature fluctuations expected to rise by 17% and their overall intensity by 20% by the year 2100, affecting areas where more than 80% of the world’s population lives.

In addition, mortality data from China and the United States reveal a strong link between daily temperature variability and increased risk of death, particularly from cardiovascular and respiratory diseases.
