A new study has warned Vietnam of deadly rising temperatures caused by inaction to reduce global emissions.

The study published in the journal Nature Climate Change, said inaction to cut emissions could result in a worst case scenario where Vietnam would experience deadly hot days for between 200 to 250 days of the year, by the year 2100.

The study also said that nearly a third of people around the world are currently exposed to deadly heat waves.

Between 1995 and 2005, Vietnam had 50 or more deadly hot days per year.

Bad heat waves are defined as when heat and humidity exceed a person’s core body temperature.

Strong heat can cause stroke-related deaths.

In 2003, a European heat wave was linked to 70,000 deaths, and similar cases have been recorded in both Russia and the US.
