Extreme weather, exacerbated by climate change, poses significant risks to blood donations and safety, potentially leading to shortages at critical times, according to a recent analysis.

The Blood Supply Crisis: How Climate Change is Impacting Donations and Demand
A new study reveals the alarming connection between climate change and the stability of the world's blood supply.
Climate change is presenting unforeseen challenges for global blood supplies, as highlighted in a recent study published in The Lancet Planetary Health. This research indicates that rising temperatures and extreme weather conditions not only inhibit blood donations but also escalate the demand for blood, straining an already vulnerable supply chain.
The ramifications of climate change are dire. According to Elvina Viennet, a lead author and infectious disease researcher at the University of the Sunshine Coast in Australia, "Any major disruptions to the availability and safety of the blood supply puts lives at risk." This is the first comprehensive global assessment articulating the effects of climate change on the blood supply crisis.
The study synthesizes various research findings demonstrating how extreme weather events—including hurricanes, floods, heat waves, wildfires, and snowstorms—negatively impact physical and mental health, contribute to the spread of infectious diseases, and create complications for blood transfusions, ultimately affecting public health. These weather events can prevent individuals from donating blood and can complicate the logistics of blood transportation and safety.
During such crises, mobile donation centers might be rendered ineffective as they cannot reach disaster-hit areas, thereby exacerbating the mismatch between supply and growing demand. As climate conditions continue to worsen globally, urgent actions are needed to address the potential blood supply shortages that could jeopardize countless lives in critical moments.
