Heat Wave Sweeps Across China, Breaking Records and Prompting Warnings.

Beijing and parts of northern China are experiencing record temperatures, with authorities urging people to limit their time outdoors. The current heat wave has been caused by warm air masses associated with high-pressure ridges in the atmosphere and compounded by thin cloud covers and long daylight hours around the summer solstice. Other countries in Asia have experienced deadly heat waves in recent weeks, which scientists say are aggravated by rising global temperatures, caused partly by the burning of fossil fuels.
