Polar bears are increasingly seeking sustenance in human trash because of melting sea ice and a loss of hunting opportunities. The result is a rise in human-bear conflict – and dead bears.
The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
ToxChips study the changes in the DNA of animals exposed to contaminants, like those found in oil spills.
The SA Agulhas II is helping South Africa to become a leader in Antarctic science.
This seemingly one-off heatwave may be a harbinger for the future under climate change.
The resting place of Shackleton’s ill-fated ship is now an international heritage site, and a reminder of how Antarctica’s place in our collective consciousness has changed since the ‘heroic age’.
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.
