Climate shocks an 'early warning call' to act on rising hunger, UN says

Climate shocks such as droughts, floods and variable rainfall, are already causing a rise in hunger, a situation UN economists describe as an “early warning call” for action on food insecurity.

News Article: Global hunger continues to rise, new UN report says

"If we are to achieve a world without hunger and malnutrition in all its forms by 2030, it is imperative that we accelerate and scale up actions to strengthen the resilience and adaptive capacity of food systems and people's livelihoods in response to climate variability and extremes," the leaders said.
