Arctic

Permafrost stores a lot of carbon, which is important in terms of climate change. However, as sea levels rise, permafrost can get covered up with water, which is a big change for the microbes that live in the permafrost. Depending on what the microbes in the permafrost are doing, the permafrost has the potential to start releasing that carbon that was previously stored. Scientists recently set out to find out what happens inside the permafrost when it ends up under the ocean, which can tell us more about the past and future of our planet.
