In 2021 the Intergovernmental Panel on Climate Change issued the first volume of its latest authoritative report on climate change. The United Nations secretary-general branded its findings a “code red for humanity”.
The emerging and predicted impacts on agriculture and food supplies are stark, according to the panel. For instance, heat waves, drought and increasing rainfall variability could adversely affect crop yields and livestock productivity. This, in turn, could cause problems with food availability and nutritional quality, as well as risks of malnutrition and hunger.
