permafrost

The DNA fragments collected from permafrost in northern Greenland unlock insights into an ancient ecosystem.

The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.

The hardy animals were pulled from the permafrost in Siberia, giving scientists the opportunity to study how they survive extreme conditions.

A complete bird specimen uncovered in northeastern Siberia is radiocarbon dated to be roughly 44,000–49,000 years old.

Insulating tundra soil with snow increased the abundance of microbial species involved in carbon dioxide and methane release.

The Lawrence Berkeley National Laboratory researcher’s work will help predict how the Arctic is responding to climate change—and the global effects of those changes.

A new species of giant virus discovered in the Siberian permafrost, where it’s been buried for 30,000 years, is reincarnated in the lab.

Researchers are using snowdrifts to artificially warm Arctic tundra during winter and finding that more carbon is released from the soil than plants can soak up from the atmosphere.
