Arctic - Arctic "report card" points to rapid and dramatic impacts of climate change

This past summer in the Arctic was the warmest since 1900, contributing to disasters across the wider region, including flooding in Juneau, Alaska and a record wildfire season in Canada.

Antarctica - Unstable Ice: Antarctic Glacier's Sudden Collapse Rattles Scientists

A recent study led by glaciologist Benjamin Wallis has revealed the alarming instability of the Antarctic’s Cadman Glacier, which rapidly lost significant ice due to ocean warming.

World - COMMENTARY COP28: Earth’s frozen zones are in trouble – we’re already seeing the consequences

As this year’s UN climate summit (COP28) gets under way in Dubai, scientists studying Earth’s frozen regions have been delivering an urgent call for action to policy makers. But is anyone listening?

World - Antarctica's ancient ice sheets foreshadow dynamic changes in Earth's future

Identifying how and why Antarctica's major ice sheets behaved the way they did in the early Miocene could help inform understanding of the sheets' behavior under a warming climate. Together, the ice sheets lock a volume of water equivalent to more than 50 meters of sea level rise and influence ocean currents that affect marine food webs and regional climates. Their fate has profound consequences for life nearly everywhere on Earth.

Norway - Could today's conservation requirements be the nail in the coffin for Svalbard's cultural heritage?

The warming in Arctic regions is happening three times faster than the global average. This has major consequences for the unique cultural monuments at Svalbard.

Arctic - Alaska senator makes new push to get Law of the Sea ratified

Alaska Senator Lisa Murkowski is making a new push to get the U.S. Senate to ratify the United Nations Convention on the Law of the Sea (UNCLOS), saying the longer the country spends on the sidelines, the more influence it cedes to other nations.

Arctic - Russia Will Fight to Protect Its Key Weapon in the Global Energy Race

After massive Russian oil and gas supplies were sanctioned following the 24 February 2022 invasion of Ukraine, LNG firmly became the world’s key swing energy supply. Russia stated just over a week ago that it would do everything it could to scupper new U.S. sanctions imposed on its Arctic LNG 2 project.

Antarctic - Ancient Landscape Discovered Beneath The East Antarctic Ice Sheet

Of particular interest to Astrobiology mission planners are the ice-covered worlds in our solar system – Enceladus, Europa, Ganymede, Mimas, Titan, etc. and the probability that they have vast oceans beneath their surfaces. As we seek to penetrate the outer surface, what sorts of geology will we find underneath? Studies in Earth’s polar region can help us develop the tools to study these icy worlds from space, on their surfaces, and one day, beneath their outer surfaces.

Arctic - Arctic shifts are driving dramatic population swings among gray whales, study explains

CORVALLIS, Ore. — Gray whales undergo substantial “boom-and-bust” population cycles in response to shifting Arctic conditions, new research reveals. Since the 1980s, scientists have observed three significant die-offs in the eastern North Pacific gray whale population.

ANTARCTICA - Increasing Melting of West AntarcticIce Shelves May Now Be Unavoidable

The rate at which the warming Southern Ocean melts the West Antarctic ice sheet will speed up rapidly over the course of this century, regardless of how much emissions fall in coming decades, our new research suggests.

Antarctica - EDITORIAL Lukewarm response to Antarctica's shrinking ice mass

SCIENTISTS have long been closely tracking developments in Antarctica, the world's only continent that is almost entirely blanketed in ice. The monitoring is critical because what happens in Antarctica impacts the entire planet.

Antarctica - Pinning point five collapsed, the sea ice barrier buttressing Thwaites and Pine Island Glacier.

Antarctica has been under heavy cloud cover, so NASA's Worldview coastline images are rare. Kris Van Steenbergen is relentlessly researching climate impacts in the Southern Ocean and West Antarctica. He may sound familiar as he broke the news of a massive iceberg wedged on a sea mountain in front of the Thwaites Glacier for 20 years finally lifted off due to warming ocean currents. I created several diaries sharing many of his tweets and researched what could go wrong in the highly vulnerable Amundsen Sea Bay as best I could.
