Climate Change and Health

Climate change is among the most important and urgent global health threats and opportunities of the 21st century.

Recognizing this, the NAM launched the Climate Grand Challenge in 2020. The Climate Grand Challenge is a multi-year global initiative to improve and protect human health and well-being — especially for populations disproportionately impacted by climate change — by working to transform systems that both contribute to and are impacted by climate change. The Climate Grand Challenge has five strategic objectives:

  1. Communicate the public health impacts of climate change, including disproportionate impacts on specific populations
  2. Develop a comprehensive roadmap for systems transformation 
  3. Catalyze the health sector to reduce its climate footprint and ensure its resilience 
  4. Accelerate research and innovation at the nexus of climate and health 
  5. Reduce climate-related health disparities

Why Climate Change Matters for Human Health

While many consider climate change to be a looming environmental threat—one that stands to impact future generations more so than today—millions of people die globally every year because of health issues linked to climate change. Further, these health threats and impacts are not evenly distributed or experienced across geographies or populations, but rather, are disproportionately burdening specific populations. The climate crisis is a public health crisis that will continue to pose significant threats in the absence of concerted action.

The Climate Grand Challenge will highlight the most robust actions to address climate change that could yield a healthier, more resilient society. The NAM will serve as a unifying hub for any organization or individual who cares about this issue to come together and take action, to ultimately catalyze a climate and health movement.

Highlighting organizational climate actions: Supports exist to help institutions in mitigating their environmental footprint. For example, IRA implementation can enable hospitals to pave a greener and more sustainable way forward while curbing costs.

Highlighting individual climate actions: Many individuals are committed to responding to climate change. For example, the NAM invited future health professionals to share their visions for how the health sector can address climate impacts on human health.
