Climate change presents a paramount threat to human health, necessitating an urgent response from healthcare professionals worldwide. The Intergovernmental Panel on Climate Change (IPCC) emphasizes the criticality of limiting global temperature rise to 1.5°C to avert catastrophic health consequences and prevent millions of climate change-related deaths. Nonetheless, even a 1.5°C increase in global heating is deemed unsafe, as each incremental temperature rise exacts a substantial toll on people's lives and well-being.

Those most severely affected by the climate crisis are often those who contribute least to its causes and possess limited means to safeguard themselves—specifically, individuals and communities in low-income and disadvantaged countries. This crisis poses a significant risk to the progress achieved in terms of development, global health, poverty reduction, and the attainment of universal health coverage (UHC). Moreover, it exacerbates existing health disparities, compounding the burden of disease and creating barriers to accessing essential healthcare services, particularly during periods of heightened need. At present, approximately 930 million people, or roughly 12% of the world's population, allocate a substantial portion of their household budget towards healthcare expenses. The repercussions of climate change exacerbate this trend, pushing around 100 million people into poverty annually.

The impacts of climate change on human health are already discernible across various domains. Extreme weather events, disrupted food systems, increased transmission of diseases, and mental health challenges are among the climate-sensitive health risks that have been magnified. These risks disproportionately affect vulnerable and marginalized populations, including women, children, ethnic minorities, impoverished communities, migrants, older individuals, and those with underlying health conditions. While accurately quantifying the precise scale and impact of these health risks remains a complex task, advancements in scientific understanding are enabling a more precise attribution of illnesses and deaths to human-induced warming.

In the short to medium term, the health consequences of climate change hinge upon population vulnerability, resilience to ongoing changes, and the effectiveness of adaptation measures. However, the long-term implications will increasingly depend on taking transformative action now to curtail emissions, prevent the breach of dangerous temperature thresholds, and mitigate potential irreversible tipping points. By mitigating climate change, we not only protect global health but also ensure a sustainable future for all. Immediate efforts are crucial to safeguard human well-being and preserve the well-being of future generations.
