The Trump administration recently rolled back a significant scientific finding, stating that climate change poses a threat to public health. This contrasts sharply with a substantial body of research reinforcing that climate change indeed harms health—resulting in thousands of deaths each year.
In 2009, the Environmental Protection Agency (EPA), under the Obama administration, concluded that climate change endangered public health. Dr. Howard Frumkin, a public health expert, expressed disbelief at the government’s decision to revoke this finding, comparing it to denying basic scientific truths.
Recent studies highlight the escalating health risks tied to climate change. A 2023 analysis in JAMA revealed that heat-related deaths in the U.S. have more than doubled over the past 25 years, from 1,069 in 1999 to 2,325 in 2023. Moreover, a 2021 study found that over a third of heat-related deaths globally could be linked to human-caused climate change, equating to approximately 9,700 deaths annually due to fossil fuel use.
In Texas, research indicates that 2.2% of summer deaths between 2010 and 2023 were heat-related, highlighting how climate change is intensifying health risks in specific regions.
The volume of research on climate change and health has exploded. Twenty-nine thousand peer-reviewed studies have been published in the past 15 years, with over 60% appearing in the last five years alone. Experts like Dr. Jonathan Patz emphasize that the evidence is clear: climate change worsens health outcomes. He points to events such as the 2021 heat dome in the Northwest, which led to over 600 deaths, as stark reminders of the dangers we face. Researchers found that climate change increased the likelihood of such events by 150 times.
When examining the impacts of climate change, studies cover various health issues—some focus on preventable deaths while others assess illnesses that don’t result in death. Attribution studies, which compare actual mortality rates to predictions based on simulations, are a growing area of research. They help clarify how much of this burden can be directly attributed to climate phenomena.
A significant study recently compiled diverse research to assess the global health costs of climate change. It connected various causes of death—from heatwaves to air pollution—and estimated the annual financial toll at around $10 billion.
The effects of climate change extend beyond physical health. Dr. Lynn Goldman notes how climate change leads to displacement due to extreme weather, underlining the mental health and well-being impacts of environmental changes.
Interestingly, while cold-related deaths have decreased, studies show that cold still causes 13 times more deaths than heat exposure in the U.S. Predictions suggest that without adaptation, total mortality from heat may rise sharply if global temperatures increase beyond certain thresholds.
In summary, the debate on climate change and public health is not merely political; it’s a pressing issue supported by a mounting number of scientific findings. As the climate crisis deepens, the implications for public health are profound, urging a deeper understanding of the interplay between our environment and well-being.
