A new report from the Lancet Countdown has revealed that climate change is severely impacting global health, with record-breaking heat-related deaths, food insecurity, and the spread of diseases in 2023. The report underscores the urgent health threats posed by rising global temperatures, as almost half of the world’s land endured extreme drought conditions for at least a month.

The report highlights that heat-related deaths have surged, particularly among people over 65, with rates increasing by 167% since the 1990s. Aging populations are especially vulnerable to these effects, with prolonged exposure to extreme heat further exacerbating the risk. Alongside this, food insecurity has intensified as climate disruptions have added 50 more days of dangerously high temperatures worldwide, affecting 151 million people with moderate to severe food shortages.

Infectious diseases like dengue, malaria, and West Nile virus are spreading as warmer climates allow them to thrive in previously unaffected areas. Rising temperatures and frequent drought have also led to significant sand and dust storms, exposing 31% more people to hazardous particulate matter and triggering health issues such as respiratory distress.

The report underscores that despite these dangers, global emissions continue to rise. Energy-related carbon dioxide emissions hit a record high in 2023, driven by a persistent reliance on fossil fuels. With fossil fuels still accounting for 80.3% of energy production, governments face mounting pressure to transition to cleaner energy sources. Experts stress that immediate action is needed to prevent escalating health crises.

The findings stress that climate inaction is no longer a distant threat but a present-day health emergency, emphasizing the critical need for solutions that not only mitigate climate risks but also protect public health.
