The Synergistic Threat of Pollution and Climate Change
Summary
This chapter examines the combined threat of air pollution and climate change, discussing how the two global problems interact and amplify one another, with implications for human health and ecological systems.
Abstract While it might be tempting to simplify our interactions with weather and longer-term climatic conditions as a simple byproduct of varying atmospheric conditions, this would be a mistake. As will be outlined in this chapter, air pollution (a nasty consequence of the mainly human activities and technology driving climate change!) by itself, is likely cardio-toxic. Moreover, concentrations of outdoor air pollution and its impact on the cardiovascular system varies according to the prevailing climatic conditions, topography and human structures/activity. Other forms of pollution, including indoor air pollution, metal pollutants, microplastics and noise pollution are also important factors in eroding the capacity of an individual’s cardiovascular (and broader cardiopulmonary) system to maintain homeostasis when confronted with provocative climatic conditions. It is for this reason that ‘pollution’ has been elevated to the status of being a “ non-traditional, major risk factor ” for cardiovascular disease. But how much does climate and climate change influence it’s impact on our heart health? To answer this question, in this chapter the synergistic threat of pollution as both a consequence and cause of climate change will be explored.

Synergistic Effects of Climate Change and Marine Pollution: An Overlooked Interaction in Coastal and Estuarine Areas
This systematic review examines how climate change and marine pollution, including microplastics, interact to produce combined effects that are worse than either problem alone. These synergistic effects in coastal areas are important to understand because they can amplify the health risks that pollutants pose to marine life and, through the food chain, to humans.
To breathe or not to breathe: Implications of hazardous air quality
This review examines the relationship between climate change, worsening air quality, and associated human health impacts, focusing on the spectrum of respiratory diseases and cancers linked to air pollution. The authors argue that governments and public health sectors must strengthen pollution control policies and reduce carbon and other pollutants to protect population health.
Research progress in ecotoxicology of climate change coupled with marine pollutions
This review examined how rising ocean temperatures and acidification from climate change interact with marine pollutants including microplastics, finding that combined stressors often produce worse effects than either alone. The research underscores that plastic pollution cannot be addressed in isolation from the broader context of global climate change.
Global distribution and coincidence of pollution, climate impacts, and health risk in the Anthropocene
Researchers analyzed the relationship between toxic pollution and climate change risk across 176 countries and found a strong correlation between the two. Low-income countries faced disproportionately higher risks from both pollution and climate impacts, while also having the least institutional capacity to respond. The study argues that pollution and climate change should be addressed jointly rather than independently, as they often affect the same vulnerable populations.
Plastic Pollution and Climate Change: Double Trouble
This accessible review explains how plastics and climate change reinforce each other — plastic production emits greenhouse gases, warming accelerates microplastic release from the environment, and microplastics themselves disrupt ecosystems that regulate climate — calling for integrated policy solutions.
