In 2022, 57 million more people were driven into crisis levels of hunger by climate extremes. This is more than double the number from 2021, and triple from 2020. At the same time, humanitarian funding remains insufficient. Rising hunger is fueled by a vicious cycle of climate change, conflict, environmental degradation, and economic shocks. Climate shocks and stresses are recurrent, and their impact is becoming more severe. These protracted situations weaken the resilience of communities leading to more devastating impacts on food security with each shock or stress period. Most food insecure people threatened by the climate crisis live in fragile contexts, prone to, or affected by, conflict. These communities require the most protection from climate extremes yet receive the least support from the international community. Action is needed now.
