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.
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.
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.
A new study suggests Antarctica's ice sheets formed millions of years before the Arctic's due to geological uplift. Gondwana's breakup caused mantle waves that raised East Antarctica, creating high-elevation terrain favorable for ice formation, even before significant global cooling.
O centenário Clube Palestra Itália em Ribeirão Preto, SP, foi vendido por R$ 6,75 milhões a construtoras que prometem revitalizar o espaço, que enfrentava dívidas e esvaziamento. O imóvel, que já foi tombado, passará por reforma sem proteção histórica oficial, mas com expectativa de preservação arquitetônica.
New research suggests Antarctica's sea ice loss, linked to cloud cover and ocean heat absorption, could accelerate global warming faster than previously thought. Recent record-low sea ice extents and higher regional temperatures signal a major climate shift, with potential for amplified warming and more severe climate impacts globally.
New research suggests Antarctica's sea ice and cloud cover have a stronger link to global warming than previously believed. The study by the European Geosciences Union (EGU) indicates potential underestimation of ocean heat absorption and climate sensitivity in current models, raising concerns about faster and more severe future warming.
Scientists have identified a massive, fan-shaped geological structure, the East Antarctic Fan-Shaped Basin Province (EAFBP), hidden beneath over three kilometers of ice in East Antarctica. This discovery reshapes understanding of Gondwana's breakup and Antarctica's ice sheet behavior.
Scientists found that soil studied by India's Chandrayaan-3 rover closely matches the chemical makeup of ALHA 81005, the first meteorite confirmed to be from the Moon. The finding links measurements from the "Shiv Shakti Statio" to the meteorite found in Antarctica, suggesting both represent the same broad category of magnesium-rich lunar crust material.
A titanosaur tail bone, discovered in Antarctica in 1985, has been identified as a dinosaur fossil decades later. The species remains unknown, but the dinosaur was approximately 23 feet long and lived when Antarctica was covered in forests.
The H5N1 strain of avian influenza has been confirmed in Western Australia after two seabirds, a brown skua and a giant petrel, tested positive. Both birds have died, marking the first time the virus has reached Australia, raising concerns for wildlife and industry.
Ribeirão Preto completa 170 anos com um rico patrimônio histórico. O g1 preparou um roteiro com 12 locais que contam a história da cidade, desde a época dos barões do café até a chegada dos imigrantes.
Over 13,000 seal pups have died on Australia's Heard Island due to H5N1 bird flu, with high mortality rates confirmed among penguins, seals, and petrels. The virus likely spread from French subantarctic islands, marking its eastward movement around the region. Australia is increasing preparedness for potential mainland incursions.
Antarctica's harsh environment has led to numerous unexplained deaths and disappearances over decades. From a young Chilean woman on Livingston Island to Scott's doomed expedition and accidents involving crevasses and storms, records are often fragmentary, leaving many events without clear closure.
Antarctica's west coast is experiencing a severe deficit of winter sea ice in the Bellingshausen Sea, with an area the size of France missing. This alarming trend raises concerns for penguins, marine life, and global sea levels, and may have intensified a recent heatwave on the continent.
An area of Antarctica comparable to France has failed to form winter sea ice in the Bellingshausen Sea, alarming scientists. This unusual event, coinciding with a heatwave, raises concerns for penguins, marine ecosystems, and sea-level rise.

Australia's One Nation party faces scrutiny over 'sloppy' financial reports with over $1m in missing assets. US President Trump accuses Iran of 'playing us for suckers' amid imminent strike threats. Thousands of Australian women face medicine uncertainty, while World Cup predictions begin.
Japanese lawmaker Mitsuhiro Yokota voiced concerns in parliament about potential future exploitation of Antarctica's vast mineral and energy resources, specifically mentioning China's interest and its resource acquisition ambitions.
Scientists discovered fossils of an intact temperate rainforest near the South Pole dating back 90 million years to the Cretaceous period. The findings, including a 3-meter root network preserved in mudstone, suggest Antarctica was ice-free and supported dense vegetation with an average annual temperature of 12°C due to higher atmospheric CO2 levels.
Scientists discovered fossilized amber beneath the West Antarctic Ice Sheet, proving Antarctica was once a warm rainforest. This finding challenges perceptions of the continent and impacts climate history simulations.
A new study reveals India and East Antarctica were once joined as a massive mountain belt, the Rayner-Eastern Ghats orogen. Rocks in India's Vizianagaram-Salur region share the same age, chemistry, and geological history as those in Antarctica, providing 'smoking gun' evidence of their shared past before drifting apart.
