Climate and Health in 2025 – How This Year's Weather is Impacting Us All
Beyond headlines of floods and heatwaves, this year’s climate is having a profound and personal effect on public health. The extreme weather events of 2025 aren’t just environmental issues—they’re human ones.

Let’s start with heat-related illness. Europe, the Middle East, and parts of Asia have endured record-high temperatures, with many cities facing over 40°C (104°F) heat for days at a time. Hospitals have reported spikes in heatstroke, dehydration, and respiratory issues, especially among children and the elderly. Cities lacking green infrastructure are especially vulnerable, with the “urban heat island” effect worsening living conditions.
At the same time, flooding from monsoons and storms has contaminated water supplies in several countries, leading to outbreaks of waterborne diseases.
