The environmental consequences of climate change such as sea-level rise, increasing temperatures, more extreme weather events, increased droughts, flooding and wildfires are impacting human health and lives. Previous studies and reviews have documented the multiple health impacts of climate change, including an increase in infectious diseases, respiratory disorders, heat-related morbidity and mortality, under-nutrition due to food insecunty, and adverse health outcomes ensuing from increased sociopolitical tension and conflicts. Indeed, the most recent Lancet Countdown report, which investigates 43 indicators of the relationship between climate change and human health, arrived at their most worrisome findings since the beginning of their on-going annual work. This report underlines that the health impacts of climate change continue to worsen and are being felt on every continent, although they are having a disproportionate and unequal impact on populations. Authors caution that these health impacts will continue to worsen unless we see an immediate international response to limiting climate change.
