Table source: Future of Humanity Institute, 2008. There have been a number of other estimates of existential risk, extinction risk, or a global collapse of civilization: Humanity has a 95% probability of being extinct in 7,800,000 years, according to J.

What are the chances of human extinction?

“Using only the information that Homo sapiens has existed at least 200,000 years, we conclude that the probability that humanity goes extinct from natural causes in any given year is almost guaranteed to be less than one in 14,000, and likely to be less than one in 87,000,” the researchers write in Scientific Reports.

Will we have another ice age?

Coming out of the Pliocene period just under three million years ago, carbon dioxide levels dropped low enough for the ice age cycles to commence. Now, carbon dioxide levels are over 400 parts per million and are likely to stay there for thousands of years, so the next ice age is postponed for a very long time.
