New Study Warns Arctic Permafrost Could Become a Major Carbon Source Earlier Than Expected
A new study in Science Advances warns that Arctic permafrost may release carbon dioxide and methane faster than previously modeled. This creates a dangerous feedback loop that could accelerate global warming significantly.
Why it matters
It suggests that climate change tipping points may be reached sooner than expected, complicating global efforts to meet emissions targets.
