Research Findings on the Effects of Climate Change on Public Health
Research has shown that climate change is already having a significant impact on public health. For example, a study published in The Lancet found that between 2000 and 2016, the number of people exposed to heatwaves increased by around 125 million. This has led to a rise in heat-related illnesses and deaths, particularly in urban areas where the urban heat island effect can exacerbate high temperatures. In addition, changes in precipitation patterns have been linked to an increase in waterborne diseases such as cholera and cryptosporidiosis.
Furthermore, climate change is contributing to the spread of vector-borne diseases such as malaria, dengue fever, and Zika virus. Warmer temperatures and changing rainfall patterns create more favourable conditions for the breeding and survival of disease-carrying mosquitoes, leading to an expansion of their geographic range. This has serious implications for public health, particularly in tropical and subtropical regions where these diseases are already endemic. Overall, research findings highlight the urgent need to address the impact of climate change on public health in order to protect vulnerable populations and prevent further harm.
