Sea ice is thinning at an alarming rate. Snow is shifting to rain. And humans worldwide are increasingly feeling the impact of what happens in the seemingly distant Arctic.
A closer look at how ice cover changed through the months offers some important insights into the role of climate change and why every year isn’t a record.
A plan for humanity’s surviving and thriving through our planetary crisis.
Some of the climate changes will be irreversible for millennia. But some can be slowed and even stopped if countries quickly reduce their greenhouse gas emissions, including from burning fossil fuels.
A particularly stormy winter has pushed perennial sea ice into the Arctic melt zone.
Emperor penguins survive in a ‘Goldilocks zone’ between too much sea ice and too little. A new study shows the risk they face from climate change.
As the climate changes, the ocean is also changing. And that’s putting our health at risk.
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.
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.
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.
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.
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.
