Study Warns of Sudden Climate Change

A report by the National Academy of Sciences finds that hard-to-predict sudden changes to Earth’s environment are more worrisome than climate change’s bigger but more gradual impacts, the AP reports.

The 200-page report “looked at warming problems that can occur in years instead of centuries. The report repeatedly warns of potential ‘tipping points’ where the climate passes thresholds, beyond which ‘major and rapid changes occur.’ And some of these quick changes are happening now.”

Science Insider: “Some sudden impacts of climate change are already under way, the report notes. Arctic warming has caused a rapid decline in sea ice cover during the past decade that could seriously affect everything from Arctic ecosystems to shipping and oil drilling. And global warming is so rapid—as fast as any warming in the past 65 million years—that species already under pressure from habitat loss and overexploitation are at greater risk of extinction.”

Politico: “The report adds to the growing body of scientific research warning of dramatic fallout from unabated climate change. Notably, it also echoes longtime warnings by activists and scientists that it is imperative to act quickly.”
