According to Srilat Kammil, head of climate change adaptation, UNDP, “With one in eight people worldwide at risk from a deadly heatwave in South Asia that has already claimed nearly 100 lives, it is time to recognize that the climate crisis is a health crisis.” This is not an isolated problem. In South Africa, recent floods have claimed more than 400 lives, violence and insecurity are on the rise in the Sahel as people struggle with hunger, malnutrition and other factors that are being made exponentially worse by climate change, and in places like Colombia, health and food security are at risk as floods displace communities and trigger disease outbreaks. This is the most urgent health and humanitarian challenge of the 21st century. A quarter of a million people are expected to die from climate change each year between 2030 and 2050 if we do nothing about it, according to the World Health Organization (WHO).” (Ngozi Ibe)
