But if things are going to get that much worse, could climate change make humans go extinct? Scientists predict a range of devastating scenarios if climate change is not kept under control, but if we just consider the direct impacts, then there’s some good news; it’s unlikely to cause our extinction.
What will cause human extinction?
Human extinction is the hypothetical end of the human species due to either natural causes such as an asteroid impact or large-scale volcanism, or anthropogenic (human) causes, also known as omnicide.
What are the chances of human extinction?

The First Humans One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
What will happen in 100 trillion years?
And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs. The Universe will be completely dark.
How long have humans existed?
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.
Will the Earth run out of oxygen?
The extrapolated data from these simulations determined that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. That’s the good news. The bad news is that once that happens, the planet will become completely inhospitable for complex aerobic life.

Will dogs become extinct?
But unlike other animals that become extinct due to environmental factors, dogs tend to disappear for more superficial reasons: they simply become unfashionable. But now, with dogs being bred purely for aesthetics, that means more breeds get lost in the fray and become forgotten like ’80s one-hit wonders.
How did humans survive the dinosaur extinction?

The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species. The first two of these are a direct result of human population growth and resource use.
Can we avoid extinction?
Scientists tell us the best way to protect endangered species is to protect the places where they live. Get involved by volunteering at your local nature center or wildlife refuge. Go wildlife or bird watching in nearby parks. Wildlife related recreation creates millions of jobs and supports local businesses.
