The importance of collecting data on climate change cannot be understated, especially when considering the impact it has on public health. In a recent opinion piece published in PLOS Climate, Jeremy Jacobs from Vanderbilt University and Shazia Khan from Yale School of Medicine highlighted the alarming rollback of government efforts to monitor climate change data and the detrimental effects this has on public health initiatives.
Climate-related disasters such as heat waves, wildfires, floods, and hurricanes can lead to a myriad of health issues, including heart disease, respiratory problems, disease outbreaks, mental health crises, and traumatic injuries. Without adequate monitoring and forecasting tools in place, public health systems struggle to prepare for and respond effectively to these events. The most vulnerable populations, including children, the elderly, and individuals with chronic conditions, bear the brunt of these impacts.
Jacobs and Khan pointed out the recent dismantling of various climate monitoring programs by the Trump administration. This includes discontinuing NOAA’s Billion-Dollar Disasters Database, the EPA’s air quality monitoring and heat index surveillance, as well as NIH funding for research on heat-related deaths, wildfire smoke exposure, and climate-related infectious diseases. The loss of these critical resources not only hinders domestic public health efforts but also has international repercussions.
In response to these troubling developments, Jacobs and Khan called on the scientific and medical communities to uphold the integrity and accessibility of climate data as a cornerstone of public health. They urged journal editors and funding agencies to prioritize research on climate and health, advocate for transparency, and resist political pressure to censor accurate terminology.
“To ignore climate data is to abandon public health in the face of its greatest modern challenge,” Jacobs emphasized. “It is to walk into the next disaster with eyes wide shut.”

The importance of safeguarding climate data for public health cannot be overstated. As researchers continue to sound the alarm on the critical link between climate change and public health, it is imperative for stakeholders to prioritize data collection and monitoring efforts to protect vulnerable populations and mitigate the impacts of climate-related disasters.
