More than 700 million years ago, planet Earth was plunged into a 57-million-year-long ice age. Australian scientists led by Dr Adriana Dutkiewicz and Professor Dietmar Müller at the University of Sydney now have an answer why this happened.
The normal processes where CO2 is removed from the atmosphere and stored permanently in rock take millions of years, where humans are releasing the same amount of CO2 in decades. That’s the problem, there are plenty of processes that naturally increase or decrease the amount of greenhouse gasses. The temperature goes up and the temperature goes down, Earth has been an ice ball for millions of years in the past.
What humans are doing now is unprecedented and every model we come up with predict an extinction level event within the next 100-200 years. Now humans as a species stand a good chance to survive, but living through an event where 95% of the worlds population dies is going to be kinda rough.
Saw that too, and would like to know more.
