Summary

Story summary

A recent study reveals that Arctic peatlands are expanding due to climate-driven increases in plant growth and moisture.
The study notes that Arctic peatlands store more carbon than all of Earth's forests combined, underscoring their key role in moderating global warming.
Researchers identify sphagnum moss as a key driver of the expansion, creating conditions that allow more peat to form.
Yet rising temperatures also increase extreme heat and wildfires, which can release stored carbon back into the atmosphere, making the balance uncertain.
