The World Health Organization (WHO) has issued a call to action, urging governments and local communities worldwide to establish robust monitoring systems for individuals most susceptible to severe heatwave-related health complications. This comes as a significant heatwave impacts the Northern Hemisphere, posing considerable risks to public health.
Certain groups are particularly vulnerable to the extreme heat, including those with pre-existing conditions like cardiovascular and respiratory diseases and diabetes. Pregnant women, children, and the homeless population are also at heightened risk. These groups require special attention and support during periods of intense heat.
Maria Neira, director of the public health, environment and social determinants of health department at the WHO, expressed deep concern regarding the impact of heatwaves on vulnerable individuals. She emphasized that extreme heat can exacerbate existing health issues, leading to potentially serious consequences.
The current heatwave is believed to be primarily driven by El Niño, a climate pattern known to influence global temperatures. However, experts also highlight the role of global warming in intensifying the issue, contributing to erratic weather patterns worldwide. While some regions grapple with extreme heat, others are experiencing devastating rainfall and flooding. Central and southern South Korea have been hit with heavy rains, while northern India has seen flash floods and landslides, resulting in over 100 fatalities since the start of monsoon season.
Looking ahead, Neira stressed the importance of decarbonizing society to mitigate the long-term effects of climate change and reduce the severity of future heatwaves. This underscores the need for sustainable practices and policies to address the root causes of climate change and protect vulnerable populations from its consequences.
