China's cities now have a better idea of what global warming is going to cost. New research warns that for every rise of one degree Celsius in global average temperatures, average electricity demand will rise by 9 percent.
And that's the average demand. For the same shift in the thermometer reading, peak electricity demand in the Yangtze Valley delta could go up by 36 percent.
The events come nearly two months into the continent's annual rainy season that extends from June to November, according to The Straits Times.
