Live in a megacity? Prepare for deadly heat even if Paris climate goals met

In a 2 degree Celsius-warmer world, Kolkata could experience deadly conditions at least once a year

Deadly heat stress is projected to affect hundreds of millions more people each year under relatively little additional climate warming. The Paris Agreement commits the international community to limit global warming to no more than 2 degree Celsius above pre-industrial (late 19th century) air temperatures, with an aspirational target of 1.5 degree Celsius. In our latest research, which looked at the impact of global temperature rises on magacities, we found that even if 1.5 degree Celsius is achieved, large increases in the frequency of deadly heat are expected.
