Climate Change Is Unleashing Flesh-Eating Fungi

Climate change isn’t just melting ice caps or fueling wildfires—it’s helping dangerous pathogens spread in ways that threaten our health right now.

Scientists are sounding the alarm about Aspergillus, a common fungus that can cause severe—and sometimes deadly—infections in humans. In extreme cases, it can invade the lungs and other organs, effectively destroying the body from the inside out. What’s even more alarming is that climate change is making this threat worse.

Recent reporting underscores just how urgent this threat has become. A new analysis highlighted in The Hill warns that climate change is enabling Aspergillus—a potentially deadly fungus—to expand into new regions as temperatures rise, putting more people at risk of infection. Researchers say warming conditions are helping these pathogens survive in environments that were once too cold, increasing the likelihood of exposure and severe illness.

As temperatures rise, fungi like Aspergillus are adapting to survive in warmer environments—including the human body. That means infections that were once rare or limited to certain regions are now spreading into new areas. At the same time, widespread use of agricultural fungicides is accelerating the rise of drug-resistant strains, making these infections increasingly difficult—sometimes impossible—to treat.

Public health experts warn that this is just the beginning. Climate change is creating ideal conditions for fungal diseases to evolve, spread, and become more dangerous. Yet our leaders are failing to treat this crisis with the urgency it demands.

The Trump Administration and Congress must stop ignoring the real-world health impacts of climate change.

We call on our leaders to:

1: Acknowledge climate change as a growing public health emergency, including its role in spreading deadly fungal infections

2: Invest in research, monitoring, and treatment for emerging fungal diseases

3: Strengthen public health systems to detect and respond to these threats

4: Take bold action to cut climate pollution and slow the warming driving these dangerous changes

We cannot afford to wait until these infections become widespread and uncontrollable. The science is clear: climate change is making deadly diseases more likely—and more dangerous.

Our leaders have a responsibility to protect us. That starts with taking climate change seriously.

Please sign the petition and demand action now.

The petition to the Trump administration and Congress reads: Take immediate action to address the growing public health threat posed by climate-driven fungal diseases like Aspergillus. Recognize climate change as a health emergency, invest in research and surveillance, strengthen public health preparedness, and rapidly cut climate pollution to limit the spread of deadly infections. The health and safety of our communities depend on urgent, science-based action now.
