A new personal view published in The Lancet Planetary Health explores how climate change may challenge the stability of global blood systems. In the paper, researchers from Australian Red Cross Lifeblood and the University of the Sunshine Coast examined how climate-driven disruptions could affect donor health, blood safety and the availability of compatible blood products.
The study is among the first to assess the effects of climate change across the entire blood supply chain, based on a comprehensive review of international literature. It outlines how extreme weather events can impede donor access, damage infrastructure and increase demand for blood, particularly during emergencies. The paper also explores how climate change may accelerate the spread of vector-borne and zoonotic diseases with transfusion-transmission potential, in addition to discussing broader health consequences of climate change.
