Climate change poses a threat to the world’s food supply over the next few decades, according to a leaked draft of a report by a United Nations panel.
The draft report by the Intergovernmental Panel on Climate Change (IPCC) indicates that rising temperatures could be helpful for producing some crops, but globally climate change will make it difficult for most crops to thrive, the New York Times reported.
Demand for food is expected to increase 14 percent per decade as the world population continues to grow.
Meanwhile, crop production could be reduced by as much as two percent for each decade for the rest of the century.
A 2007 report from the IPCC predicted that any losses due to global warming would be offset by gains in colder areas. Now the panel says that is not the case, and there will be losses across the board as carbon emissions continue to rise.
Crops are more sensitive to heat waves than scientists expected.
They see plants and animals moving to new areas to escape rising temperatures and others threatened with extinction.
While hundreds of billions of dollars have been spent to reduce carbon emissions based on the findings of the IPCC, analysts claim those efforts are inadequate.
