Dramatic changes in the Arctic are being driven by high temperatures and intense wildfires. After storing carbon dioxide for millennia in frozen soil, the Arctic tundra has now become a source of emissions.
Researchers have used computer models to forecast when the Arctic Ocean might experience its first ice-free day.
These fires puzzle scientists because they appear in early May, way ahead of the usual fire season in the far north, and can reignite for a number of years.
The Earth's atmosphere just pulled a surprising U-turn! The polar vortex, a swirling mass of cold air circling the Arctic, has unexpectedly reversed its direction.
Beneath one Arctic island's permafrost, millions of cubic meters of methane are trapped—and scientists have now learned that it can migrate beneath the cold seal of the permafrost and escape.
A new study finds that Arctic sea ice could disappear in the summers as early as the 2030s, a decade earlier than previously thought
Researchers looked at soil and lake sediment from Lake Hazen, the largest lake by volume north of the Arctic Circle. Sequencing segments of DNA and RNA found in the soil, the scientists sought to identify the pool of viruses present in the environment.
Researchers found "giant" viruses – several times larger than typical viruses – affecting microscopic algae just below the boundary between fresh water and salt water.
For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October. The delayed annual freeze has been caused by extreme warmth.
After 13 months of collecting data, history’s largest Arctic research expedition returned with grim news. “We witnessed how the Arctic Ocean is dying,” the mission leader said.
Nearly after 30 years, the World Meteorological Organization confirms that the Northern Hemisphere in Greenland has a minus minus 69.6 C. This new data provides a benchmark for understanding climate change.
High temperatures in the Arctic have puzzled scientists for decades. Now, a new study supports predictions that the Arctic could be free of sea ice by 2035.
An emergency was declared after 20,000 tonnes of diesel leaked into a river when a tank at a power plant near the city of Norilsk, Russia, collapsed at the end of May. The spill contaminated a 350 sq km area.
Earlier this year, most of the ozone around 18 km overhead had vanished completely. But now we can breathe a sigh of relief as its healed up again. However, it's hard to predict just how rising temperatures will affect it in future.
A new analysis of numerous climate models predicts the Arctic Ocean will become ice-free in the summer before the mid-point of this century – a startling forecast that persists even if we cut down atmospheric CO2 emissions.
