Climate-driven extreme heat may make parts of Earth too hot for humans

If global temperatures increase by 1 degree Celsius (C) or more than current levels, each year billions of people will be exposed to heat and humidity so extreme they will be unable to naturally cool themselves.

Unbearable heat could make some parts of the world uninhabitable if warming continues

Researchers have recently found that if the Earth’s temperatures rise one degree Celsius over current measurements, each year countless individuals will experience unbearable heat and humidity levels that will render their bodies incapable of cooling themselves.

Too hot for humans: Rising temperatures could soon make parts of Earth uninhabitable

Vast regions of our planet, where over half the global population resides, may soon become uninhabitable due to extreme heat

Extreme heat, coupled with chronic health issues, is killing elderly New Yorkers

As global warming temperatures rise people are more vulnerable because of age and medical conditions and face a greater danger

Your body can build up tolerance to heat. Here’s how.

Safe ways to train your body to build tolerance in the heat

Heat can kill on the job, and these workers are dying

Deaths from the heat waves have filled some hospitals to pandemic levels and OSHA is in the process of drafting a heat standard for work places.

As heat records fall, how hot is too hot for the human body?

Heat and humidity put people at greatly increased risk, and the combination gets dangerous at lower levels than scientists previously believed.

The heat index reached 152 degrees in the Middle East — nearly at the limit for human survival

As the Northern Hemisphere approaches summer’s peak, heat is testing the limits of human survival in Earth’s hottest spots — and demonstrating the extremes that are increasingly possible and probable against the backdrop of accelerating global warming.

As a summer heat wave pummels the US, an expert warns about the dangers of humidity – particularly for toddlers, young athletes and older adults

Dr. W. Larry Kenney, professor of physiology and kinesiology at Penn State University, who discussed why humid heat can be dangerous to human health and, in some cases, life-threatening.

Sweating keeps you cool, but climate change is making it harder

Our bodies couldn't endure the summer heat without sweating. But as the climate gets hotter, sweat isn't cooling us off like it used to.
