Some areas in the tropics face famine because of failing food production, an international research group says.
The Climate Change, Agriculture and Food Security (CCAFS) predicts large parts of South Asia and sub-Saharan Africa will be worst affected.
Its report points out that hundreds of millions of people in these regions are already experiencing a food crisis.
“We are starting to see much more clearly where the effects of climate change on agriculture could intensify hunger and poverty,” said Patti Kristjanson, an agricultural economist with the CCAFS initiative that produced the report.
A leading climatologist told BBC News that agriculturalists had been slow to use global climate models to pinpoint regions most affected by rising temperatures.
Climate models show that the tropics should be least affected by global warming, and satellite data shows almost no change in tropical temperatures over the last 30 years.
One would expect that a “leading climatologist” would already know this
