For 37 years researchers heated a patch of forest floor to see what climate change would do to the soil — and the carbon everyone assumed was locked away started leaking out on schedule

A decades-long heating experiment reveals that Earth's most stable soil carbon isn't as permanent as climate models assumed—and microbes may be awakening it just as the planet warms.
