Wilder winds are altering currents. The sea is releasing carbon dioxide. Ice is melting from below.
The ice shelf was cracking up. Surveys showed warm ocean water eroding its underbelly. Satellite imagery revealed long, parallel fissures in the frozen expanse, like scratches from some clawed monster. One fracture grew so big, so fast, scientists took to calling it “the dagger.”
Scientists are warning of dramatic changes at one of the biggest glaciers in Antarctica, potentially within the next five to 10 years.
The highest temperature ever recorded in the Arctic, 38C (100F), has been officially confirmed, sounding "alarm bells" over Earth's changing climate.
While a reduction in frozen ocean surface is one of the most widely recognised impacts of Arctic warming, it has also long been anticipated that a warmer Arctic will be a wetter one too, with more intense cycling of water between land, atmosphere and ocean.
The warship HMS Terror lies at the bottom of the Arctic Ocean in the Northwest passage, lost in 1848 after two grueling years stuck in the Arctic ice. Rescue missions launched to recover the ship in 1851 suffered the same fate, crushed under the year-round ice that encased Northern Canada and th ...
The Arctic is once again at the centre of geopolitical and strategic discussions, mainly for one reason – climate change – and it is imperative to act now, write Virginijus Sinkevičius and Boris Herrmann.
Feb. 27 (UPI) -- The planet's oceans are capable of storing a lot more heat than Earth's atmosphere.
Researchers race to retrieve ice amid protests by local residents.
Arctic sea ice volume plunged to new lows last month with a July average of just 8,800 cubic kilometers (2,111 cubic miles) of ice remaining atop the Arctic Ocean.
July 25 (UPI) -- Wildfires are raging across the Arctic as warm, dry conditions persist across the region. Satellite images have revealed wildfires burning in Alaska, Greenland and throughout Siberia.
Thwaites glacier is likely to thaw and trigger 50cm sea level rise, US study suggests
Even if global warming can be kept to a 1.5-degree Celsius rise from pre-industrial times, the Antarctic Peninsula is set for some big changes.
Scientists have identified more than 50 new lakes of liquid water lying under the Greenland Ice Sheet.
Oxygen concentrations in both the open ocean and coastal waters have declined by 2-5% since at least the middle of the 20th century.
Scientists have found that on the desolate Antarctic peninsula, nitrogen-rich poop from colonies of penguins and seals enriches the soil so well that it helps create biodiversity hotspots throughout the region.
The second largest Emperor penguin colony on Earth has suffered a "catastrophic" breeding failure after nearly all chicks born over three years died as their icy Antarctic habitat shrinks, researchers said Thursday.
