As frozen ground thaws in the Arctic, dead plants and animals locked in soils for thousands of years start to decay, releasing methane and carbon dioxide. Those gases trap heat from the sun and warm the planet. And the more the planet warms, the more Arctic permafrost thaws. This is just one feedback loop among many that most climate modeling has largely overlooked. A recent study published in the journal Environmental Research Letters examined four sources of greenhouse gases from natural syste
