Title: Addressing the Climate Health Crisis: An Urgent Call to Action for Human Welfare
The climate change crisis we're experiencing today is no longer a distant threat. It's here, affecting every aspect of our lives, including our health. While devastating wildfires, unprecedented hurricanes, and scorching heatwaves make headlines, the long-term effects on our physical and mental well-being often go unnoticed. But the connection between a warming planet, extreme weather patterns, and biodiversity loss, and our health is undeniable.
As a healthcare professional and policy-maker, I believe we must acknowledge climate change as a public health crisis and take immediate action. The consequences are immediate, widespread, and deeply inequitable. However, solutions are within our reach, and it's time for us to come together and implement them before the crisis worsens beyond our control.
How Climate Change Harms Health
The negative impact of climate change on health is far-reaching. From extreme weather events to shifting disease patterns, the consequences are profound and interconnected. Here are some ways I, as a medical professional, see climate change affecting health:
- Heat Stress and Chronic Illnesses:
Record-breaking heatwaves are becoming the norm, pushing human bodies beyond their limits. High temperatures exacerbate chronic conditions like cardiovascular and kidney diseases, often leading to fatal outcomes. In 2023 alone, more than 2,300 Americans died from extreme heat. Prolonged exposure to high temperatures can also lead to heat-related illnesses in outdoor workers and vulnerable populations.
- Air Pollution and Respiratory Health:
Fossil fuel combustion, one of the major drivers of climate change, contributes to poor air quality. Wildfire smoke, ground-level ozone, and fine particulate matter can lead to respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD). These health issues disproportionately affect marginalized communities, who are more likely to live near pollution sources.
- Disease Transmission and Biodiversity Loss:
Climate change is altering habitats, allowing disease-carrying vectors like mosquitoes and ticks to expand into new territories and transmit diseases like Lyme disease, alpha-gal syndrome, and dengue fever. Additionally, biodiversity loss disrupts ecosystems, increasing human exposure to zoonotic diseases, those that jump from animals to humans.
- Mental Health and Climate Anxiety:
Climate change has a significant psychological toll. Displacement due to extreme weather events, increased anxiety, depression, and post-traumatic stress disorder (PTSD) are all consequences of the climate crisis. Heat stress can also contribute to higher rates of domestic violence and suicide.
- Disproportionate Impact on the Most Vulnerable:
The health impacts of climate change are deeply inequitable. Low-income communities, marginalized groups, and seniors experience greater exposure to environmental hazards and have limited access to resources for adaptation.
A Call to Action: Promoting Health and Resilience
Considering the health impacts of climate change, coordinated action is necessary. By addressing the root causes of climate change and investing in health resilience, we can promote and protect human well-being while mitigating the crisis.
- Transition to Clean Energy:
Reducing greenhouse gas emissions is essential for mitigating climate change. Policies that transition energy systems to renewable sources like nuclear, wind, and solar can slow global warming and improve air quality, preventing respiratory diseases and saving lives.
- Strengthen Health Care Leadership:
The healthcare sector can do more in the face of climate change. Hospitals and clinics can adopt sustainable practices, reduce unnecessary waste, transition to clean energy sources, and enhance disaster preparedness.
- Scale Public Health Resilience:
Public health systems play a crucial role in protecting communities. Surveillance programs for climate-sensitive diseases, early warning systems for extreme weather events, and community education campaigns can help mitigate health risks and protect populations.
The health impacts of climate change are not inevitable. With bold leadership, innovative policies, and collaboration, we can build a healthier and more resilient future. The time to take action is now.

In response to the climate change crisis, we need to prioritize clean energy transitions to reduce greenhouse gas emissions and improve air quality, thereby preventing respiratory diseases and saving lives. Moreover, healthcare institutions should adopt sustainable practices and strengthen disaster preparedness to lessen the health impact of extreme weather events.
Climate change is exacerbating wildfires, leading to increased air pollution and subsequent respiratory health issues, particularly affecting marginalized communities living near pollution sources. Additionally, the warmer climate is facilitating disease transmission and biodiversity loss, posing risks of zoonotic diseases and higher incidences of heat-related illnesses.
