From more frequent wildfires to rising sea levels, climate change is disrupting ecosystems and upending once-stable weather patterns. One particularly alarming consequence of rising global ...

Researchers predict that the first ice-free day in the Arctic could happen within three years, potentially leading to devastating extreme weather events across Europe.

Can We Refreeze the Arctic’s Ice? Scientists Test New Geoengineering Solutions Researchers are trying to rebuild sea ice above the Arctic Circle so it can reflect the sun’s warming rays ...

Arctic sea ice had its weakest winter buildup since record-keeping began 47 years ago, a symptom of climate change that will have repercussions globally, scientists said Thursday.

The amount of springtime sea ice in the Arctic set a record low this month, continuing a trend of shrinking ice at the top of the world.

Arctic temperatures spiked 36 degrees Fahrenheit, or 20 Celsius, above normal. By the end of the month, sea ice was at its lowest level ever recorded for February.

A summer in which the Arctic Ocean features almost entirely open water could be coming even sooner than expected and may become a regular event within most of our lifetimes, a new study says.

Science New Study Reveals Arctic Ice, Tracked Both Above and Below, Is Freezing Later Climate change is affecting the timing of both the freezing of the ice and its melting in the spring.

The Arctic is seeing a rapid decline in sea ice even during the cold winter months when it should be recovering from the summer melt. Scientists say that one, often overlooked, factor is playing a ...
