As temperatures continue to rise across the globe, scientists are warning about a new threat creeping through Europe—dangerous fungi like Aspergillus are spreading into regions where they previously couldn’t survive. According to Newsweek journalist Emma Marsden, recent studies show that the warming climate is creating ideal conditions for these fungi to flourish, putting both humans and animals at greater risk.
Aspergillus fumigatus is especially concerning. It thrives at body temperature, grows rapidly in hot compost, and easily infects the lungs after inhalation of its microscopic spores. It’s already a major cause of illness in people with asthma or weakened immune systems. As Exeter University professor Elaine Bignell explains, this fungus is now becoming harder to treat, as frontline antifungal drugs are losing effectiveness due to overuse in agriculture.
Climate change isn’t just warming the planet—it’s altering the balance of life. Wet-dry weather cycles caused by extreme events disturb soil and unleash fungal spores into the air. These spores can cause deadly infections, such as aspergillosis, especially in people recovering from severe illness like COVID-19. According to the study by Norman van Rhijn, the range of A. fumigatus may increase by 77 percent by 2100. That means more people, livestock, crops, and even corals could soon be at risk.
Worryingly, fungi like Aspergillus flavus not only threaten health, but also contaminate food crops with cancer-causing toxins, worsening global food insecurity. With few effective treatments and over 90% of fungi still unidentified, experts say we are unprepared for the rise of fungal threats.
Our world isn’t just heating up—it’s changing in ways we don’t fully understand. That’s why now is the time to rethink how we farm, what we eat, and how we treat the planet. Supporting plant-based agriculture and rejecting pesticide-heavy systems are real ways to slow this fungal surge and protect both animals and people.
