“’How screwed are we?’ I always understand that,” said Dr. Deutsch. “If we do nothing, we are screwed.”

Nations are still a long way from taking the necessary steps to prevent catastrophic climate change. Last month, United Nations secretary-general António Guterres warned that a critical goal is to limit the average global warming since pre-industrial times to 1.5 degrees Celsius (2.7 degrees Fahrenheit).on life support

The International Energy Agency, a group created to ensure a stable energy market worldwide, said last year: countries should immediately stop approving new fossil fuel projects. They did not stop, and the Russian invasion of Ukraine added to the call for more drilling in the name of energy security.

In an interview, Dr. Deutsch and Penn said they felt like ignored scientists in their latest movie, “Don’t Look Up,” when a comet slams into Earth. a metaphor for climate change. As in the movie, the planet is at a crucial moment and gives people living today tremendous power to determine the future.

Dr. “With great power comes great responsibility,” Deutsch said. And we are learning about our strength, but not about our responsibility – to future generations, but also to all other lives with whom we have shared the planet for millions of years.

Pippa Moore, a professor of marine science at the University of Newcastle in England, who studies the effects of climate change on the ocean and was not involved in the research, described it as comprehensive.

“This article adds to the massive evidence that unless more is done to reduce our greenhouse gas emissions, our marine systems are on track to see major shifts in where marine species live and significant extinction events as demonstrated in this article that could rival previous mass extinction events,” he said. .
