Some ecological risks  are particularly sensitive to warming. For example, warm-water coral reefs are already experiencing High risk levels and are expected to face Very High risks under 1.5℃ of glob- al warming . Some societal risks, such as human mortality due to extreme heat, also are sensitive to warming. A medium-warming scenario  reduces projected global average mortality due to heat from seven deaths per 10,000 people yr-1  by 2100 to ~1/10,000 yr-1, assuming high-vulnerability societal conditions . At the national level, without considering adaptation, reductions in a broader measure of mortality are projected across a range of countries including Colombia, the Philippines, and several in Europe , and exposure of the US population to high- mortality heatwaves is reduced by nearly half . Without considering changes in exposure or vulnerability, warming of 1.5-2°℃  reduces global mortality impacts from an increase of 2.1-13.0% to 0.1-2.2%  and impacts in China from up to 4/10,000 yr-1  to 0.3-0.5/10,000 yr-1 .
