In the summer of 2019, a man found himself stranded on the 405 freeway in Washington State when his car broke down. While waiting for a tow truck in the sweltering heat, he felt an unsettling pressure in his chest. Once at the hospital, doctors delivered the shocking news: he had experienced a heart attack, despite being generally healthy. Dr. Mark Vossler, a retired cardiologist who treated him, explained that the extreme heat likely played a role in his declining heart health. This isn’t an isolated case. According to Dr. Vossler, heat-related heart issues could soon be a common story, thanks to climate change.
The U.S. Environmental Protection Agency (EPA) recognized in 2009 that greenhouse gases threaten public health. However, recent government actions have attempted to downplay these risks. For instance, in February 2026, the Trump administration rolled back critical climate regulations, aiming to disregard the established data on climate-related health threats.
Climate change doesn’t just affect the environment; it’s a serious health crisis. A 2021 study found that 85% of the world’s population has been negatively impacted by climate change events, with climate inaction contributing to millions of deaths each year and incurring billions of dollars in damages globally.
Dr. Vossler, who cared for many vulnerable patients, emphasized the visible impacts of climate change on their health. He noted that extreme heat can significantly increase the risk of cardiovascular issues. His concerns resonate with other health professionals like Dr. Laalitha Surapaneni, who works in Minneapolis. She has seen firsthand how climate factors, such as wildfire smoke, can lead to severe health consequences. Studies suggest that breathing in wildfire smoke can increase the risk of cardiac arrest by up to 70%. For many individuals without access to air conditioning, the situation worsens.
Dr. Surapaneni has been proactive in her approach, offering protective advice to her patients, such as using masks and utilizing air filters. But she feels the weight of the limitations in her ability to protect them fully. The complexity of the situation is amplified by economic factors, leaving many without adequate resources for health and safety.
The ever-increasing health impacts of climate change should leave us all concerned. However, there is hope. States like New York and Colorado are taking initiative. For example, New York’s congestion pricing aims to reduce emissions while enhancing urban life. Colorado is investing heavily in its electrical grid, paving the way for cleaner energy options.
Experts agree that we have the tools and knowledge needed to combat climate change effectively. But we must act now to create a healthier future for both people and the planet. By following science and implementing sound policies, we can avoid the most dire consequences of climate change and ensure better health outcomes for all.
