An increase in global warming from 1.5 to 2 degrees Celsius above late 19th-century levels would cause tens of thousands of extra deaths in China's cities every year, researchers reported Tuesday.

Even if one assumes future adaptations to cope with scorching heat—better public health services, more air conditioning, easy access to clean drinking water—the half-degree bump in temperature would likely result in some 30,000 additional heat-related deaths per year, they reported in the journal Nature Communications.

Improvements - Infrastructure - Preparedness - Mortality - Percent

Without those improvements in infrastructure and preparedness, excess mortality would go up another 50 percent.

"Our study quite clearly demonstrates the benefits of limiting global warming to 1.5C," co-author Buda Su, a scientist at Xinjiang Institute of Ecology and Geography in Urumqi, China, told AFP.

Temperatures - Degrees - Fahrenheit - Benchmark - Droughts

Average global temperatures have already risen 1C (1.8 degrees Fahrenheit) above the preindustrial benchmark, enough to trigger longer and more intense droughts and heatwaves.

The start of the 21st century has seen several especially lethal heatwaves.

One - Europe - Deaths - Mid-to-late - Year

The one that gripped Europe in 2003 resulted in more than 70,000 deaths above what would have been expected in a typical mid-to-late 20th-century year.

Unprecedented high temperatures in western Russia, including Moscow, led to more than 50,000 excess deaths in the summer of 2010.

July - Month - Globe - June - Rash

July 2019 was the hottest month across the globe ever recorded, and June saw a rash of record temperatures in the northern hemisphere.

Heatwaves are especially deadly when combined with high humidity, and when night temperatures do not drop by much.
