The Arctic tundra is warming at an alarming rate, approximately four times faster than the rest of the planet. Soil microbes play a crucial role in the carbon cycle, breaking down organic matter and releasing carbon dioxide (CO2) into the atmosphere. As the Arctic tundra warms, the soil microbes’ activity is expected to increase, leading to higher CO2 emissions. This phenomenon is particularly concerning because the Arctic tundra stores large amounts of carbon in its soil, making it a significant player in the global carbon cycle.
