Data from the 2022 report suggests that climate change is currently affecting every pillar of food security. Rising temperatures and extreme weather events threaten crop yields, by directly shortening the growth season of crops by 9.3 days for maize , 1.7 days for rice, and 6 days for winter and spring wheat. The extreme heat was also associated with 98 million more people reporting moderate to severe food insecurity in 103 countries in 2020 than annually between 1981 and 2010.
It also finds that on average, 29 percent more land was affected by extreme drought annually between 2012–2021, compared to what was measured between 1951–1960. These droughts putClimate change is also affecting the spread of infectious diseases. The report finds that the length of time suitable for malaria transmission rose by 32.1 percent in highland areas of the Americas, and 14.9 percent in Africa in 2012-2021, when compared to 1951-1960.
