Humans adapted to heat early on. In Africa, the climate selected for traits that helped them stay cool. Also, humans had physiological mechanisms that reduced the rate of metabolism and that modified the sensitivity of sweat glands to provide an adequate amount for cooldown without the individual becoming dehydrated.

Climatic adaptations limits to adaptations that have been established, characterizing species that live within the specific climate. It is different from climate change adaptations which refers to the ability to adapt to gradual changes of a climate. Once a climate has changed, the climate change adaptation that led to the survival of the ...
Climate change adaptation is the process of adjusting to the effects of climate change. These can be both current or expected impacts. [1] Adaptation aims to moderate or avoid harm for people, and is usually done alongside climate change mitigation. It also aims to exploit opportunities. Humans may also intervene to help adjust for natural ...

In some regions, the rise in temperature and humidity may be too severe for humans to adapt to. [261] With worst-case climate change, models project that almost one-third of humanity might live in Sahara-like uninhabitable and extremely hot climates. [262] These factors can drive climate or environmental migration, within and between countries ...
Through deforestation and agriculture, some scientists have proposed a human component in some historical climatic changes. Human-started fires have been implicated in the transformation of much of Australia from grassland to desert. [26] If true, this would show that non-industrialized societies could have a role in influencing regional climate.
Human-caused global warming made July hotter for four out of five people on Earth, with more than 2 billion people feeling climate change-boosted warmth daily, according to a flash study. More ...
