Climate change also means many diseases that are transmitted through blood, such as dengue fever, West Nile virus and malaria, will spread to more regions as the insects that spread them find new regions with suitable temperatures for living. (Free use image)

(Bloomberg) — Climate change and increasingly extreme weather are taking a toll on global supplies of blood, endangering the lives of people with life-threatening injuries and conditions, a new study has found.

Extreme weather events and natural disasters such as bushfires and floods, fueled by rising global temperatures, are disrupting medical professionals in their efforts to collect, test, transport and store blood, according to a study published in The Lancet Planetary Health this week. Such events make it harder for potential blood donors to travel to donation locations and slow down the transport of blood products which have a short shelf life and are highly sensitive to temperature variations.
