In a new study, a team of geologists and biologists led by CU Boulder resurrected ancient microbes that had been trapped in ice—in some cases for around 40,000 years. The study is a showcase for the planet’s permafrost. That’s the name for a frozen mix of soil, ice and rocks that underlies nearly a quarter of […]
We can’t see them, but there are more microbes — tiny fungi, bacteria, worms and other living things — in a teaspoon of soil than there are people on Earth. Hungry as you and me, those microbes gobble up bits of plant and animal material. And just like you and me, soil microbes release greenhouse […]
A long-feared scenario in which global warming causes Arctic permafrost to melt and release enough methane—a potent greenhouse gas–to accelerate warming and cause catastrophe probably won’t happen. That is the conclusion of a study appearing in the journal Science that began more than 20 years ago as a query posed by Jeff Severinghaus, a geoscientist at the Scripps Institution […]
