Arctic's Dramatic Changes: Worrying Trends In Snow, Ice, Wildfires And More
The Arctic can feel like a far-off place, disconnected from daily life if you aren't one of the 4 million people who live there. Yet, the changes underway in the Arctic as temperatures rise can profoundly affect lives around the world.

Plankton’s Ability To Sequester Carbon Is Influenced by Ocean Density, Study Shows
A study published in Royal Society Open Science explores how changes in ocean density influence marine plankton, particularly the foraminifera species Trilobatus trilobus, in incorporating carbon into their shells. These organisms play a key role in the carbon cycle by sequestering carbon in the ocean floor after death. The study, led by Dr Stergio...

"City Under Ice": NASA Discovers Secret US Military Base 100 Feat Beneath Greenland Ice Sheet
The discovery was made in April, when a NASA Gulfstream III aircraft flew over the area, revealing the remnants of Camp Century, a long-abandoned Cold War-era military base.

Did Earth Once Freeze Completely? New Evidence Found in Colorado Rocks
Recent research in Colorado’s Pikes Peak has uncovered crucial evidence supporting the Snowball Earth hypothesis. The discovery of Tava sandstone formations suggests that Earth experienced a global ice sheet about 700 million years ago. Using advanced radiometric dating, researchers pinpointed the formation of these sandstones to between 690 and ...

Rare Sea Smoke and Streaming Snow Phenomena Captured Near Pine Island Glacier
In October 2024, Pine Island Glacier displayed unusual atmospheric phenomena, including rare sea smoke and blowing snow. Captured by NASA's Landsat 8, these events were visible due to clear skies. Strong winds pushed warmer water to the surface, creating sea smoke, while blowing snow from the West Antarctic Ice Sheet influenced the glacier’s land...

Antarctica's 'Doomsday Glacier' Is Heading For Collapse Sooner Than Expected
The scientists predict that Thwaites Glacier and the Antarctic Ice Sheet could collapse within the next 200 years.

Antarctica Was Last Ice-Free 34 Million Years Ago: What Triggered This Climate Shift?
Antarctica, which is nearly four times the size of the United States, was not always covered in ice. The last time it was ice-free was 34 million years ago during the Eocene-Oligocene boundary. At that time, global temperatures were higher, and carbon dioxide levels in the atmosphere were much higher than today. However, a significant drop in CO2 l...

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...

The Day After Tomorrow Was Just A Warm-Up. Real Danger Looms, Warn Scientists
A new study has revealed that predicting the timing of catastrophic climate events, such as the collapse of the Atlantic Meridional Overturning Circulation (AMOC), is extremely difficult.

Antarctic Study Reveals "Tipping Point" For Runaway Melting Of Ice Sheets
Scientists have discovered a new tipping point toward "runaway melting" of Antarctic ice sheets, caused by warm ocean water intruding between the ice and the land it sits on, according to a study published on Tuesday.

Scientists Discover Giant Virus On Greenland Ice Sheet, Could Slow Down Melting
The team collected samples from ice sheets, including dark ice, ice cores, red and green snow and melting holes.

Breaching 2-Degree Goal Could Melt Massive Ice Sheet On Earth: Study
Breaching the Paris Agreement's temperature goal of two degrees Celsius could significantly melt the Filchner Ronne Ice Shelf in Antarctica, the second largest ice sheet on Earth, and could substantially contribute to raising global sea levels.

Greenland's Ice Shrinking At 30 Million Tonnes Per Hour, Warns New Study
The study revealed that the Greenland ice sheet has lost approximately 5,000 square kilometers of ice at its edges since 1985, equivalent to a trillion tons of ice.

Greenland Ice Sheet Shrunk By 5,091 Sq Km In 4 Decades: Study
The Greenland Ice Sheet lost 5,091 sq km (1930 sq miles) of area between 1985 and 2022, according to a study in the journal Nature published on Wednesday, the first full ice-sheet wide estimate of area loss on that scale.

Antarctic Ice Sheet Collapse Closer Than Thought, Reveals Octopus DNA
Scientists investigating how Antarctica's ice sheets retreated in the deep past have turned to an innovative approach: studying the genes of octopuses that live in its chilly waters.
