Recent Extreme Weather Events

On July 24, 2015, the temperature reached 50.3°C (122.5°F) near Ayding Lake in Xinjiang
Province. This was the highest temperature ever recorded in China.7 Other heat records have
been broken in China in recent years:

● On July 20, 2017, Shanghai had its hottest day ever, with the temperature reaching
40.9°C (105°F).8

● In 2013, several southern and eastern provinces had the most severe heat wave
in at least 140 years. Chinese authorities declared the heat a “level 2” weather
emergency—a designation previously used only for typhoons and flooding.9

● The warmest years since Chinese scientists began gathering temperature records in
the early 1950s are 2015 (first), 2007 (second), 2017 (third) and 2016 (fourth).10

Heavy rainfall events in China are increasing in frequency and severity. A 2016 study found
that rainstorm days have increased 10% while light rainy days have decreased 13% since 1961.
Another study found that rainfall in southern China in 2015 was 50% greater than the 1971–
2000 average and that “[t]he rain fell in a series of heavy storms, causing severe flooding in
many cities with impacts that included loss of life.” In July 2007, the worst rainstorms in 115
years hit Chongqing, causing dozens of deaths and extensive property damage. In July 2012,
the heaviest rainfall in 60 years hit Beijing, leaving 37 people dead.11

Droughts have also been a problem. In 2017, parts of Inner Mongolia experienced the worst
drought on record. In 2016, drought days in northeastern China were 37% above average. In
2007, a severe drought struck parts of southern China. Reservoirs shrank, and parts of the
Yangtze River dropped to the lowest levels since records were first kept in the 19th century
(probably due not just to drought but to withdrawals).12
