The first United Nations Food Systems Summit (UNFSS), scheduled for September, could be as historic to food system transformation as the Rio Earth Summit of 1992 was to climate change. Rio sparked the creation of the Intergovernmental Panel on Climate Change, or IPCC, which has brought scientists and governments around the world together and has greatly increased consensus and understanding of the severity of our global climate crisis. Its Sixth Assessment Report, released this year, was its greatest call to action yet: Climate change is widespread, rapid and intensifying.
