Tropical regions facing lethal conditions due to climate change

The article published in the journal Nature Geoscience focuses on the ability of humans to adapt to increasing heat. It is concerning that as global temperatures increase and the wet bulb temperature (a measure of 35 degrees Celsius comprising of air temperature and humidity) is likely to be reached in many tropical areas, the effect of the high temperature on skin will mean that humans will be unable to cool themselves.

The risk of this temperature being reached in tropical regions is high with scientists warning that the world's temperature increase will need to be capped at 1.5 degrees Celsius. However, even with a 1 degree increase there are warnings of severe health implications for millions of people.

Around 40% of the World's population live in the tropical regions where there are concerns and many of the people likely to be affected are living in LICs. This will therefore put more at risk as governments will struggle to fund strategies to help people, such as cooling shelters.
