In an increasingly polarizing world, the discussion surrounding human rights remains at the forefront of all that we do as a society. People are becoming more aware, as, these days, violations are displayed right before our eyes. With a click of a button or a swipe of the thumb, people are able to see travesties occurring throughout all parts of the world. Developments in technology help us remain knowledgeable about such issues, but what about the offenses that we don’t see—the silent killers that we chalk up to poor fate, to chance? What about the violations in which we ourselves play a major role? These are urgent questions that researchers at the Duke School of Medicine are working to answer, with a specific focus on the deadly impacts of climate change.

In times of crisis, the most disadvantaged communities bear the greatest burden. The researchers recognize that climate change is no different and have strategized ways to reverse these effects. They presented their research in a recent talk, titled Climate Change and Human Health: Creating a Strategic Plan for Duke’s School of Medicine. Associate Professor and lung disease expert Dr. Robert Tighe led the conversation.

While presenting his research, Tighe identified a major shift in sea surface temperature trends, noting that the trend has deviated greatly from the statistical norm. Although the reasons behind this shift are not fully understood, it is believed to have serious implications, as excess heat poses risks to human health. According to the Centers for Disease Control, increasing temperatures and carbon dioxide have the potential to impact water quality, air pollution, allergens, and severe weather conditions. These conditions, in turn, bring forth respiratory allergies, cholera, malnutrition, and cardiovascular disease, to name a few. Tighe’s research goes beyond the general effects of these issues; it delves into how they disproportionately impact the most vulnerable members of society: children, the elderly, low-income communities, and communities of color.

On a local scale, Tighe highlights that many in these vulnerable positions often lack access to the healthcare necessary to mitigate these impacts. For instance, low-income citizens are often unable to afford the costs associated with repairing the physical damage climate change inflicts on their homes, leaving them exposed to pollutants and the effects of environmental toxins. The elderly also find themselves in similarly precarious scenarios, as many of these situations require evacuation—something not always feasible for those in fragile health. Consequently, they too are left exposed to pollutants and dietary challenges exacerbated by climate change.

On a global scale, these issues heavily impact countries in vulnerable positions. The United States, China, India, the European Union, and Russia are among the largest contributors to carbon emissions. However, the consequences of this burden fall disproportionately on countries like Bangladesh, Haiti, Mozambique, small island nations, and others. Due to their geographic locations, climate change brings far more than just hotter days—it brings devastating hurricanes, tsunamis, cyclones, and widespread malnutrition. The limited financial resources in these nations make rebuilding and mitigating these impacts extraordinarily challenging, especially as many climate effects are recurring. This disparity is particularly frustrating, as these countries contribute only a fraction of the world’s carbon emissions.

This is precisely what Tighe’s work aims to address. He is working to connect the science on climate change effects, researched by those in the School of Medicine, with that of the Nicholas School of the Environment. Referring to this as an interdisciplinary issue, Tighe believes that the place to begin is within the community. He emphasizes the importance of starting with the people of Durham: What do they need? How can we best help them? How does this affect our own backyard? He stresses the importance of outreach, educating the community on how climate has long-term impacts on their health. Tighe also underscores the need to view this as an opportunity to combine diverse strengths to address the crisis from every angle.

In the face of a climate crisis that goes beyond borders and affects the most vulnerable among us, Tighe’s and his fellow researchers’ work is a call to action. By fostering collaboration between scientific fields and engaging directly with local communities, he develops an approach that is both comprehensive and compassionate.  His work reminds us that addressing climate change isn’t just a scientific or political issue—it’s a deeply human one, demanding a united effort for the wellbeing of all under the sun.
