This article outlines how climate changes threaten population health and the ultimate survival of the species on earth. Climate change is currently having wide-ranging and mostly adverse impacts through multiple pathways. Warming poses direct health threats via exposure to extremes of heat beyond physical tolerance of species on earth. Ecological systems threatened by climate change concern food yields, infectious pathogens, and river health. As this article explains, a warming climate delivers significant changes to climate systems, which in turn, have profound impacts on ecosystems. It also describes the links between climate change interfering with ecosystems and social infrastructures and human health and well-being. The burden of ill-health attributable to climate change is likely to aggravate, and in some cases even provoke, further economic decay, social fragmentation, and political destabilization, especially in the developing world and countries with unstable governments.

Keywords: ecosystem; health hazards; survival of species; exposure to heat; physical tolerance
