Climate change is no longer a distant threat—it’s a growing health emergency. From rising respiratory and cardiovascular diseases to mental health stress and vector-borne illnesses, extreme weather is escalating public health risks. This Thought Leadership Report by Primus Partners unpacks the deep links between climate and health, noting that 3.3–3.6 billion people live in climate-vulnerable areas, with India facing severe impacts—from projected GDP losses to child malnutrition. The report calls for urgent, justice-driven action, especially for marginalised groups, and outlines a multidimensional roadmap that includes resilient healthcare systems, green urban planning, crisis communication, and targeted risk mapping. Dive in to explore how climate-resilient health systems can create a safer, more equitable future.
