Arctic Could Witness First Ice-Free Day In 3 Years, Study Reveals
Arctic sea ice has been melting at an unprecedented rate of more than 12 per cent each decade, according to NASA.

Arctic Ocean Likely to Experience Ice-Free Day by 2027, Study Warns
A study published in Nature Communications predicts the Arctic Ocean could face its first ice-free day as early as 2027, marking a critical environmental milestone. Conducted using 11 climate models and 366 simulations, the research highlights the urgent need for emission reductions. The loss of sea ice in the Arctic exacerbates global warming thro...

Polar Bears in Alaska Face Rising Pathogen Threats Due to Climate Change
Polar bears in the Chukchi Sea are increasingly exposed to pathogens like Toxoplasma gondii, brucellosis, and canine distemper due to warming climates. Researchers revealed a significant rise in pathogen antibodies in polar bears since the 1990s, linking this trend to reduced sea ice, altered diets, and human interaction. The findings raise concern...

Study Warns Melting Arctic Ice Could Disrupt Ocean Currents in Europe
Scientists from UiT The Arctic University of Norway have issued a stark warning regarding the impact of melting Arctic sea ice on global ocean circulation patterns. Their recent study highlights that significant inflows of freshwater from melting sea ice into the Nordic Seas have historically led to dramatic cooling in northern Europe. By analysing...

Greenland's Fossils Reveal an Ice-Free Tundra Less Than a Million Years Ago: Report
Recent research reveals that Greenland, now 98% covered in ice, was almost entirely ice-free at some point in the last million years. Fossils of plants like willow and Arctic poppy, found in an ice core sample from the island’s center, suggest a once-thriving tundra ecosystem. This discovery is significant because it challenges previous beliefs t...

Polar Bears At Risk Of Starvation Due To Longer Ice-Free Arctic Periods
Polar bears in Canada's Hudson Bay risk starvation as climate change lengthens periods without Arctic Sea ice, despite the creatures' willingness to expand their diets.

Arctic Is Warming Nearly Four Times Faster Than the Rest of the World – New Research
A new study has suggested that the Arctic has warmed nearly four times faster than the rest of the world over the past 43 years. This means the Arctic is on average around 3 degree Celsius warmer than it was in 1980. The Arctic sea ice is covered in a bright layer of snow which reflects around 85% of incoming solar radiation back out to space.

Scientists Discover Unique Group of Polar Bears Relying on Glacial Ice in Southeast Greenland
Scientists have discovered a unique group of polar bears with distinct behaviour in southeast Greenland, that have remained isolated for hundreds of years. These polar bears are genetically different from other polar bears. While polar bears in the Arctic region usually depend on sea ice to hunt seals, the new group of polar bears appears to have ...

Emergence Of Deadly Virus May Be Linked To Melting Arctic Sea Ice: Study
Decline of ice in the Arctic sea can lead to the emergence of a deadly virus that could threaten marine life in the North Pacific, says a recent study.

Scientists Find Arctic Ocean Sea Ice Loaded With Microplastics
At first glance, it looks like hard candy laced with flecks of fake fruit, or a third grader's art project confected from recycled debris. In reality, it's a sliver of Arctic Ocean sea ice riddled with microplastics.

NASA Baffled By Mysterious Ice Circles In The Arctic
Somewhere in the Arctic sea ice, where the temperatures are typically below freezing on even the balmiest days, there is a random pattern of holes, and NASA - the literal rocket scientists who took us to the moon and want to take us to Mars - can't figure out what they are.

Here's Why 2 Degrees Celsius Global Warming Cap Won't Save Arctic Sea Ice
Even if humanity stops global warming in its tracks at two degrees Celsius, long seen as the guardrail for a climate-safe world, Arctic sea ice will still disappear in some years, scientists have warned.

Thinning Arctic Sea Ice Lets In Light, Prompts Algae Bloom: Study
Climate change is stirring life in the Arctic Ocean as thinning sea ice lets in more sunlight, allowing microscopic algae to bloom in the inhospitable region around the North Pole, scientists said on Wednesday.

More Extreme And Unusual Weather In 2017: UN Agency
Extreme weather and climate conditions, including Arctic "heatwaves", have continued into 2017, after global temperatures set record last year and the world witnessed exceptionally low sea ice and unabated ocean heat, the UN weather agency said.
-
The Arctic Is 'Behaving So Bizarrely'
Last month, temperatures in the high Arctic spiked dramatically, some 36 degrees Fahrenheit above normal - a move that corresponded with record low levels of Arctic sea ice during a time of year when this ice is supposed to be expanding during the freezing polar night.
