The Trump administration has taken a controversial step by deciding to rescind the 2009 endangerment finding, which formally recognized that six greenhouse gases, notably carbon dioxide and methane, pose a threat to public health and welfare.

theconversation.comhcn.orgThis decision, made on February 12, 2026, has drawn sharp criticism from health professionals who argue that the administration's dismissal of climate change's health risks is not only factually incorrect but also poses serious dangers to Americans' health and safety.

hcn.orgthefulcrum.usExperts in medicine, epidemiology, and environmental health have presented growing evidence that ties climate change to various health issues.They emphasize that climate change exacerbates extreme heat, increases air pollution, and intensifies the frequency of extreme weather events—all of which have dire consequences for public health.
One of the most pressing concerns is the rise in extreme heat.The accumulation of greenhouse gases in the atmosphere traps heat, leading to higher global temperatures.

hcn.orgData indicates that heat-related deaths have increased by 23% globally from the 1990s to the 2010s, with the US experiencing significant fatalities, such as those during the 2021 Pacific Northwest heat dome.

In addition to heat, climate change is linked to extreme weather events that carry their own health risks.Warmer air can hold more moisture, resulting in increased rainfall and more intense storms, leading to flooding.

The relationship between climate change and air quality is another critical concern.Increased wildfires, exacerbated by climate conditions, worsen air quality across the country.

Infectious diseases also pose an increasing threat as a result of climate change.Rising temperatures enhance mosquito populations, which are vectors for diseases like dengue fever and chikungunya.

Despite overwhelming evidence linking climate change to health risks, the Trump administration's decision to dismiss these dangers is alarming.
Sources:
hcn.orgthefulcrum.usTheir actions align with a broader agenda that undermines climate regulations, including efforts to subsidize fossil fuel industries that contribute to these health hazards.

theconversation.comExperts argue that acknowledging and addressing climate change can also yield health benefits.Transitioning to cleaner energy sources and enhancing public health measures can lead to improved air quality and a reduction in chronic diseases.
