China is reeling from its worst flooding in a decade. At least 700 people have been killed and millions displaced by torrential rains. The rains began in southern China in May after a drought; now more than half of the country is feeling monsoon-like storms. Officials blame La Niña for lower sea temperatures, which lead to the downpours. The Chinese government is reporting some improvement in conditions there, with a Yangtze River tributary near Chongqing, in the southwest, dropping 16 feet. If the Yangtze were to flood, hundreds of villages would be engulfed.
