If current trends continue, it is projected that one in three people on Earth will live in dangerously hot areas by 2080.
According to the Intergovernmental Panel on Climate Change, it is estimated that the average global temperature could rise by up to two degrees Celsius over the next few decades.
This change is known as the planetary warming threshold and has the potential to drastically increase the risk of heat-related illnesses and death for those living in many already hot areas. Furthermore, heat waves are expected to become much longer, more frequent, and more intense, putting millions of lives at risk.
