Study: Rising Temperature Fluctuations Increase Global Health Risks

A recent scientific study warns of a growing rise in both the frequency and intensity of sharp temperature fluctuations, noting that they have become a direct threat to global public health.

Conducted by researchers from Nanjing University and the Institute of Atmospheric Physics of the Chinese Academy of Sciences, the study indicates that this phenomenon is increasing significantly, particularly in regions located at low and mid latitudes. The researchers attribute this trend mainly to greenhouse gas emissions resulting from human activities.

According to the climate projections outlined in the study, the frequency of extreme temperature fluctuations is expected to increase by 17%, while their overall intensity is projected to rise by around 20% by the year 2100. These changes would affect regions inhabited by more than 80% of the world’s population.

The study also analyzed mortality records from China and the United States, revealing a strong link between daily temperature variability and increased mortality risks, especially deaths related to cardiovascular and respiratory diseases.
