An expedition is departing from Murmansk to test a reusable stratospheric platform for Arctic exploration. Developed to monitor high latitudes without foreign satellites, the system combines a biodegradable balloon with an autonomous airplane-type platform.
An Antarctic cold snap brought freezing conditions, hail, and rare snowfall to New Zealand cities including Wellington and Dunedin, causing highway closures and record electricity demand.
A study by the Alfred Wegener Institute and MARUM reveals that most ancient carbon released from thawing Arctic permafrost is buried in seafloor sediments rather than converted into greenhouse gases, as microorganisms preferentially consume fresher marine organic matter.
The 2016 Ross Sea Region Marine Protected Area agreement, established by CCAMLR, created the largest marine reserve of its time around Antarctica. It was a landmark for ocean conservation, achieved after years of negotiation and compromise among 24 member states and the EU, despite geopolitical tensions and fishing interests.
A 60% drop in humpback whale sightings off Western Australia and rare seabird appearances on Australia's east coast signal potential disruptions in the Southern Ocean. These events coincide with persistent marine heatwaves and the confirmed presence of H5N1 bird flu, prompting scientists to call for urgent, coordinated monitoring.
Unusual drops in humpback whale sightings and rare seabird appearances off Australia coincide with persistent marine heatwaves in the Southern Ocean. Scientists are concerned these events signal broader changes in ocean conditions, potentially linked to climate change and disease risks like H5N1.
China's newest Antarctic research base, Qinling Station, opened in 2024, already sources over 60% of its energy from wind, solar, and hydrogen power, moving away from traditional diesel. China aims for 100% renewable energy at all its Antarctic stations by 2035.
A nearly 14 km long iceberg grounded near Coulman Island, Antarctica, blocked emperor penguins' foraging routes, causing a 69% decline in chick numbers during the 2025 breeding season. This highlights how local physical barriers disrupt access to essential resources for wildlife.
Antarctica's Concordia Station recorded a temperature of minus 119.4°F (minus 84.1°C) on July 18, marking its coldest reading in 16 years and the lowest officially reported anywhere globally since 2012. Scientists attribute this extreme cold to a combination of polar winter, high elevation, and exceptionally stable weather patterns.
Donald Trump predicts Greenland will be under US control by January 2029, reiterating his long-standing push to acquire the Danish territory for national security. This ambition has previously strained relations with European allies, who view it as a threat to Greenlandic sovereignty.
A new study reveals North American beavers have been colonizing parts of the Canadian Arctic since 2008, expanding northward due to climate change. Researchers combined tree-ring analysis of beaver-chewed shrubs with satellite images to reconstruct their activity, offering a new method for monitoring environmental change in remote regions.
The US Coast Guard Cutter Munro actively monitored Chinese research ships Xuelong and Xuelong 2 as they transited northbound through the US exclusive economic zone and extended continental shelf in the Bering Sea towards the Arctic, marking the first such transit this year.
The floating Arctic research station 'Tara' has departed Lorient, France, for a two-year mission to drift with sea ice. An international team will collect over 10,000 samples to study climate change's impact on the rapidly transforming polar region.
Arctic sea ice decline has resumed with a record winter reduction between 2024-2025, ending a previously observed slowdown. Researchers attribute the temporary reprieve to natural ocean variations, warning of ongoing climate crisis impacts.
Russia's commercial seaports saw a 5.8% increase in cargo turnover from January to June 2026, reaching 451.452 million metric tons. Growth was noted in Caspian, Arctic, Far Eastern, and Azov-Black Sea basins, while the Baltic basin experienced a decline.
China's Foreign Ministry spokesperson Mao Ning stated that China opposes the "Chinese threat" myth and the escalation of tensions in the Arctic, in response to NATO Secretary General Mark Rutte's remarks.
China's ambition for independent leadership in the Arctic is unlikely to be realized without Russia's cooperation, according to Irina Strelnikova, an expert at HSE University. She cited China's lack of territory above the Arctic Circle and Russia's unique nuclear icebreaker fleet as key factors.
South Korea's sole icebreaker, the Araon, begins its 17th Arctic mission on Saturday for 83 days. The expedition aims to collect data for developing and operating Arctic shipping routes, investigating climate change, and the seabed environment.
Scientists have detected nanoplastics in Antarctic soil for the first time, specifically in the McMurdo Dry Valleys. The study, published in Scientific Reports, identified fragments from tyre wear and common plastics, suggesting both local human activity and long-range atmospheric transport as sources. This discovery highlights the pervasive nature of plastic pollution, reaching even remote, pristine environments.
Russia's Vostokgosplan has created a comprehensive plan to adapt Arctic Zone infrastructure to permafrost degradation. The plan includes 20 measures, a monitoring system, and pilot projects, aiming to ensure infrastructure stability and resident comfort.
Scientists on the Arctic Floating University expedition are sampling Barents Sea bottom sediments to study radioactivity dynamics. Bottom sediments are considered more informative than seawater for tracking radioactive elements and pollutants.
Ankara'da düzenlenen 36. NATO Zirvesi'nin ardından konuşan Genel Sekreter Jens Stoltenberg, zirvenin "NATO sonuç üretiyor" mesajı verdiğini belirtti. Savunma harcamalarındaki artış, yeni askeri kabiliyetler ve Ukrayna'ya destek gibi konulara değinen Stoltenberg, ittifakın birliğini ve geleceğe hazırlığını vurguladı. Bir sonraki zirvenin Arnavutluk'ta yapılacağı açıklandı.
Norway's defense minister, Tore Sandvik, stated that allies are already working on Arctic security, pushing back on Donald Trump's renewed pressure over Greenland. Sandvik emphasized Greenland's sovereignty as part of Denmark and highlighted Norway's focus on tracking Russian submarine movements in the "Bear Gap" as crucial for Arctic security, suggesting that "the way to protect Greenland starts here."
US President Donald Trump reiterated his desire for the US to control Greenland, citing its strategic importance for global security and protection, while stating it's 'not important' for Denmark. Denmark and Greenland's leadership have rejected the demand.
