In North Dakota the waters kept rising. Swollen by more than a month of record rains in Saskatchewan, the Souris River topped its all time record high, set back in 1881. The floodwaters poured into Minot, North Dakota's fourth-largest city, and spread across thousands of acres of farms and forests. More than 12,000 people were forced to evacuate. Many lost their homes to the floodwaters.

Areas where food supplies could be worst hit by climate change have been identified in a report.

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.

Global food output may be hurt as climate change brings more extreme weather over the next decade, with China likely set for harsher droughts and North America getting heavier rain, said the World Meteorological Organization.

Global warming is already cutting substantially into potential crop yields in some countries — to such an extent that it may be a factor in the food price increases that have caused worldwide stress in recent years, researchers suggest in a new study.

Wheat yields in recent years were down by more than 10 percent in Russia and by a few percentage points each in India, France and China compared with what they probably would have been without rising temperatures, according to the study.
