Supercomputer predicts climate disaster on the planet

13 july 2023

A team of Swiss scientists together with colleagues from the USA, China, Ireland, Finland and Sweden ran a climate simulation on a supercomputer that predicted a climate disaster for the Earth, reports aif.ru.

The computer generated 4000 scenarios for 15 regions of the world until 2100.

"Approximately 70% of scenarios predict that the world will exceed the global warming mark of 1.5 degrees Celsius in the next five years," the authors of the study reported.

In their opinion, these 1.5 degrees will become a safety border, after which the consequences of global warming will become irreversible and catastrophic.

"We examined 18 uncertainty factors, including population and economic growth, climate sensitivity, resource potential, the impact of changes in agriculture and forestry, the cost of energy technologies and the separation of energy demand from economic development," the news source quotes the head of the energy systems modeling program James Glynn.
