China is experiencing its most severe heat wave in a century, with temperatures reaching up to 38 degrees in Shenzhen, leading to economic losses due to damaged crops and increased vegetable prices. The heat wave has caused a 20% increase in vegetable prices year on year and is expected to decrease production in northeast China, threatening China's food independence. The heat wave could also decrease China's GDP growth by 1-1.5 points. The heat wave is also impacting other countries in the region, and China is 30 times more vulnerable to climate change than other countries due to its urbanization and energy consumption, particularly coal.
