Russia is attempting to claim more of the Arctic seabed, an area rich in oil, gas and minerals. It’s also expanding shipping and reopening Arctic bases. Here are two things the U.S. can do about it.

Belugas use sound to communicate, navigate the dark marine environment and find food. But climate change is opening up Arctic waters to more sound, and could affect the health and survival of belugas.

The Arctic has been a remote place for much of its history. But climate change is bringing global problems and opportunities to its door.

For 200 years, a small number of countries have exploited the marine wildlife of Antarctica, often with devastating impact on their populations.
Arctic sea ice levels have been falling for several decades.
The pattern of autumn sea ice growth has been completely disrupted. The director of the National Snow and Ice Data Center explains what’s happening.

The Laptev Sea is one of the Arctic’s biggest nurseries of new sea ice in winter, but Siberia’s record summer heat may have halted production.

Extreme shrinkage of summer sea ice is just the latest evidence of rapid Arctic warming – and what happens in the Arctic doesn’t stay there.

Scientists find oceanic heat has overtaken atmospheric heat as the main cause of melting.
This Arctic heat wave has been unusually long-lived. The darkest reds on this map of the Arctic are areas that were more than 14 degrees Fahrenheit warmer in the spring of 2020 compared to the recent 15-year average.

The Arctic is warming about twice as fast as the planet as a whole, with serious consequences. Scientists have been warning about this for decades.
Temperature anomalies from March 19 to June 20 2020. Red colors depict areas that were hotter than average for the same period from 2003-2018; blues were colder than average.
Models have predicted for some time that with every degree of global warming, the Arctic will see double or more.

Understanding sea ice loss requires expensive and difficult expeditions. Scientists have developed a new model that predicts the growth of small ponds on sea ice more efficiently.

How sea water circulates underneath Antarctic ice shelves is a vital missing link in climate change projections.
Over 100,000 narwhals swim the Earth’s Arctic waters.
The long tusk of the male narwhal earned these whales their fanciful nickname. But there’s more to these Arctic mammals than their unique spiral tooth.

Emperor Penguins thrive in harsh conditions, but a new study shows that their fate depends on human action to slow global warming and associated loss of sea ice.
Land clearing, cattle populations and carbon emissions stand alongside temperature as important measures of climate change.
What if the nightly news had regular updates on forest clearing, ocean temperatures and fossil fuel consumption? These indicators sit alongside temperatures as signs of climate change.

Warm summers aren’t the only threat to Arctic ice – increasingly intense winter storms are also weakening and reducing ice cover.
Warming in the Arctic is more intense than it is in the rest of the world.
More than 600 experts will spend the next year drifting in Arctic waters to gain a better understanding of how climate change is affecting the region and how it can be fought.

Studies show that the Arctic is heating up twice as fast as the rest of the planet.
