Climate change doesn’t just threaten the planet; it’s threatening the very systems that sustain human life. One of the most significant ways climate change is linked to global health is through its impact on infectious diseases. Warmer temperatures and erratic weather patterns expand the reach of diseases like malaria, dengue, and Lyme disease. Areas previously unaffected by these diseases are now seeing outbreaks, as shifting climates allow disease-carrying insects to thrive. The World Health Organization estimates that by 2030, climate change could cause an additional 250,000 deaths each year from heat-related illnesses, malnutrition, and infectious diseases.

Air pollution, a direct result of burning fossil fuels, further exacerbates the health crisis, causing  respiratory problems, including asthma and bronchitis, and contributing to heart disease and premature death. More than 90% of the world’s population breathes air that exceeds WHO’s safety limits, further highlighting the urgent need for cleaner energy solutions.

Despite the overwhelming challenges, there is hope. The growing recognition of the link between climate change and health has led to new, integrated approaches that address both issues simultaneously. Renewable energy sources, like wind and solar power, offer a solution to reducing both carbon emissions and air pollution. Cities worldwide are embracing green infrastructure, from urban forests to green roofs, which help mitigate heat stress while improving mental and physical health. These solutions are already making a measurable difference in reducing the health risks associated with climate change.

International cooperation also provides a glimmer of hope. The 2021 COP26 summit showed a global commitment to tackling the climate crisis with a focus on public health. Countries have pledged to reduce emissions, invest in clean energy, and enhance healthcare systems to cope with the increasing environmental stressors. While progress has been slow, the momentum is building, with health experts and environmentalists joining forces to advocate for stronger climate action.

At the individual level, there’s much that can be done. Reducing your carbon footprint, whether by driving less, choosing energy-efficient appliances, or eating more plant-based foods, makes a significant difference. Supporting policies that prioritize both climate action and public health can drive systemic change. And by voting for leaders committed to tackling these crises, individuals can help accelerate the changes necessary for a healthier planet.

The fight against climate change is also a fight for global health but with collective action, a healthier, more sustainable future is within reach.
