Approximately what percent of land is uninhabitable due to climate?

25%

Explanation:

Some places on Earth have a climate that is unsuitable for human life. Almost one-fourth of the Earth (25%) has this kind of climate. It can either be too cold (like on the north and south pole) or too hot (like in the deserts) for people to have a normal life.

For example, the coldest recorded temperature on the Earth is on East Antarctic Plateau, where it can go up to minus 100 degrees.

Oymyakon in Siberia, Russia is the place with the coldest climate with human inhabitance, even though the temperature can reach minus 71 degrees Celsius (-96.16 Fahrenheit).

If climate changes continue at this rate, much more of the world will be affected.
