World food crisis looms if carbon emissions go unchecked, UN says

The impacts of climate change on land will raise food prices and risk widespread food instability, says the IPCC's latest report. But there are solutions.

The impacts of climate change on land are already severe and will substantially increase food prices, risking widespread food instability, says a new report from the Intergovernmental Panel on Climate Change (IPCC).

Rising temperatures may also reduce the nutritional value of crops and will significantly reduce crop yields, the report said.

Extreme weather events have already increased in size and intensity and are playing a role in food price spikes in recent years, said Cynthia Rosenzweig, Coordinating Lead Author of the IPCC Special Report and a climatologist at the NASA Goddard Institute
