If average global temperatures rise by 2 degrees Celsius, the risk of food supply instabilities “are projected to be very high,” according to the report.

If climate change is left unchecked, rising temperatures, extreme weather and land degradation could trigger a global food crisis, according to a report released Thursday by a United Nations panel.

The report from the Intergovernmental Panel on Climate Change examined how agriculture will be affected by global warming, as well as how food production and other changes in land use are expected to contribute to climate change in the future.

The panel concluded that if average global temperatures rise 2 degrees Celsius over the pre-industrial average — something that previous reports by the panel have suggested could happen by the end of the century — the risk of food supply instabilities “are projected to be very high,” according to the report, which was written by more than 100 scientists from around the world.
