Though Greenland sharks generally live in icy waters, one was recently caught in the Caribbean.

The Scientist spoke with Ohio State University microbiologist Matthew Sullivan about a recent expedition that identified thousands of RNA viruses from water samples and cataloged them into novel phylogenic groups.

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 decrease in growth appears to be associated with increasing water temperatures, affecting animals throughout the marine food web.

Dyck was widely respected for working alongside indigenous groups as he studied polar bears on their ancestral lands.

Environmental engineer Gil Bohrer discusses how long-term, large-scale tracking data can shed light on the unexpected ways animals are responding to changes in the Arctic.

Knock-on effects of melting sea ice in the Arctic may be to blame for a spate of gray whale deaths along their migration route from Mexico to Alaska.

For the past two years, the charismatic marine mammals have washed up on Pacific shores in record numbers. Scientists investigating the strandings suspect warming waters and melting sea ice are partly to blame.

The discovery puts a nail in the coffin of a long-held assumption about the limits of where the essential process can occur.

The possibly record-breaking temps follow the warmest winter on record in the region.

Chlorofluorocarbons and other substances were banned in 1989 under the Montreal Protocol.

A group of scientists in northern Norway are using the technique to measure biodiversity’s response to past and present climate change.

The funding future is uncertain for researchers studying topics including cancer, stem cells, and the Arctic.

Nest predation of shorebirds that raise young in the Arctic are up threefold since the mid-20th century, and climate change may be to blame, according to a study.

If left unchecked, greenhouse gas emissions will drive ocean temperatures up, affecting wildlife in these regions.

A group of around 300 whales produced 184 distinct songs over just a few years, according to a new study.

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.

S. Allen Counter pursued scientific questions within various cultures throughout the world.

Phytoplankton in the Arctic Ocean could amplify warming near the North Pole.
