Ancient plant and animal DNA buried in Arctic sediments preserve a 50,000-year history of Arctic ecosystems, suggesting that climate change contributed to mammoth extinction.
Improvements in our ability to forecast oceanic conditions weeks to months in advance will help communities, industries, and other groups prepare amid a changing climate.
The forecasting tool IceNet promises to be a useful tool for evaluating sea ice loss in the Arctic. But ethical and logistic considerations have to be taken before scientific and Indigenous communities start working together.
If climate change throws off the seasonal freeze-thaw cycle of Arctic sea ice, it could trigger a reinforcing cycle of sea ice melt in parts of the Canadian Arctic.
New satellite observations of polar stratospheric clouds have advanced our understanding of how, when, and where they form, their composition, and their role in ozone depletion.
Last winter, an unprecedented high-pressure system over the Arctic drove nearly a quarter of old sea ice into warmer waters, putting it at greater risk of melting.
When permafrost thaw reaches concentrations of ice underneath the surface, it may trigger local soil instability.
A new study shows that icebergs may initiate submarine landslides when they collide with the seafloor.
A new study demonstrates the benefits of crowdsourcing science using sailboats to better understand the impact of melting sea ice in the Arctic.
