• Higher temperatures have resulted in range expansions for key disease carriers, such as mosquitoes. The incidence of malaria, dengue, and haemorrhagic fever is correlated with temperature, precipitation, and humidity. Overall, improvements in public health are expected to lead to a decline in infectious disease, but climate change will act as an impediment.
• By 2050, 200 million more people might be exposed to malaria, due to global warming.
• Globally, 76% of the population derives most of their daily protein from plants. If CO2 levels continue to rise as projected, researchers estimate that roughly an additional 150 million people may be placed at risk of protein deficiency because of elevated levels of CO2 in the atmosphere.
• Due to climate change, yields of most important crops in developing countries would decline, by 2050, exposing an additional number of people to malnutrition, including 25 million children.
• Residents of crowded cities (especially in South Asia) may experience growing health problems due to rising heat and humidity levels.
• The risk of extreme summer heat events in Europe has already quadrupled, with serious implications to the ecosystem and human health.
