Buckle up for a trip back in time to the last ice age. We touch down in the mammoth steppe, and discover that this was a surprisingly productive ecosystem--it supported a high density and diversity of animals, including mammoths and other big hairy herbivores. So productive, it has been called the 'Serengeti of the North'. And it turns out that the very nature of this ecosystem--the interactions between herbivores, plants, microbes in the guts of animals, microbes in the soil, little di...

Carbon in the Ground 1: A spaghetti bolognese of organic matter
Carbon-rich organic matter is just like spaghetti bolognese: a tangle of carbon chains that's vulnerable to being eaten. In order to keep your spag bol safe, special conditions are required (tupperware, fridge), and it's just the same for organic matter in the ground. Why does this matter? As the climate warms, so does the very ground beneath our feet. And where that ground is frozen (large parts of Canada, Alaska and Siberia) warming can lead to thawing, allowing carbon-rich soil to come ou...
