Climate Change: A Threat to Our Health and Safety
In early 2026, a significant shift occurred in U.S. climate policy. The administration decided to revoke a 2009 finding that identified six greenhouse gases as threats to public health. This move was met with criticism, as many experts argue that climate change poses serious health risks.
The Dangers of Extreme Heat
Extreme heat is one of the most immediate dangers. As greenhouse gases trap heat, temperatures rise, leading to more frequent and severe heatwaves. This can be deadly, especially for those working outdoors, the elderly, and people with chronic illnesses.
- Heat-related deaths have been increasing globally, with a 23% rise from the 1990s to the 2010s.
- In the U.S., the 2021 Pacific Northwest heat dome was a stark reminder of this danger.
Extreme Weather Events
Climate change also intensifies extreme weather events:
- Warmer air holds more moisture, leading to heavier rainfall and more powerful storms.
- This increases the risk of flooding, which can cause injuries, water contamination, and mental distress.
- Droughts, another consequence of climate change, disrupt food supplies and worsen respiratory illnesses.
Air Pollution and Health Risks
Air pollution is another major concern:
- Wildfires, fueled by hotter and drier conditions, release toxic particles that can penetrate deep into the lungs.
- These particles can trigger heart attacks and increase the risk of lung cancer.
- Warmer temperatures favor the formation of ground-level ozone, a pollutant that irritates the heart and lungs.
Infectious Diseases
Infectious diseases are also on the rise due to climate change:
- Mosquitoes, which thrive in warmer temperatures, spread diseases like dengue fever and chikungunya virus.
- Warmer temperatures also increase the risk of foodborne illnesses and fungal infections.
Mental Health Impacts
Climate change affects mental health as well:
- Disasters can lead to anxiety, depression, and post-traumatic stress.
- High temperatures are also linked to increased rates of violent crime and suicide.
The Administration's Decision
The evidence linking climate change to health risks is overwhelming. Yet, the administration's decision to revoke the endangerment finding ignores this evidence. This move is part of a broader set of policies that cut support for renewable energy and subsidize fossil fuel industries.
Addressing Climate Change for Health Benefits
However, addressing climate change can also improve health:
- Cleaner vehicles and electricity mean cleaner air, which reduces the risk of heart and lung disease.
- Promoting walking and cycling can lower chronic disease risks.
- By tackling climate change, we can promote good health.
