Extreme heat waves are affecting China's eastern and southern provinces, with temperatures in megacities like Shanghai and Hangzhou exceeding 40 degrees Celsius. Shanghai experienced its highest temperature of the summer at 40.4°C, leading to the issuance of a red alert for high temperatures. Local authorities in Hangzhou have banned non-essential outdoor lighting to conserve energy as power demand surged. Experts predict two more heat waves until mid-August, with projections indicating this summer may be the warmest in modern history. Residents are coping by limiting outdoor activities, with some reporting conditions that feel like stepping into an oven. Despite the scorching weather, relief is expected late this month as temperatures may begin to ease.
