It sounds like something from a sci-fi blockbuster: giant viruses are living in the Arctic ice. But the earth is not doomed \- these supersized infectious agents could actually help slow the melting of the ice, helping to alleviate global warming. According to findings published in May in the journal Microbiome, researchers at Denmark’s Aarhus University discovered the giant viruses in Greenland. They suspect they may slow the growth of black snow algae - which contributes to ice-melt. This ancient Antarctic ice reveals 50,000 years of vital climate change history'We can make a difference': Em...

Climate change is putting countless marine animals under pressure but jellyfish could actually benefit from warming ocean waters. A study by researchers at Germany’s Alfred Wegener Institute (AWI) looked at eight different species of Arctic jellyfish. They exposed them to rising water temperatures, sea ice retreat and other changing environmental conditions through computer models. Scientists found that by the second half of the century, seven of the eight species could expand their habitat polewards under these conditions. Simulations showed that the lion’s mane jellyfish - one of the biggest...

The last remaining privately owned land on the Svalbard Archipelago in Norway, "with significant environmental, scientific and economic importance" is on sale, for €300 million. "This is a once-in-a-lifetime opportunity to acquire land on one of the world-famous Svalbard islands," said Will Matthews, Head of Farms & Estates at Knight Frank to Euronews Business. Global real estate consultancy Knight Frank, which is marketing the Company holding 100% of the land, said that it is a "unique environmental, philanthropic and conservation opportunity." The land has a strategic location and is of geop...

By The Conversation Paul Hunter , University of East Anglia Scientists have recently revived several large viruses that had been buried in the frozen Siberian ground (permafrost) for tens of thousands of years. The youngest virus to be revived was a sprightly 27,000 years old. And the oldest – a Pandoravirus – was around 48,500 years old. This is the oldest virus ever to have been revived. As the world continues to warm, the thawing permafrost is releasing organic matter that has been frozen for millennia, including bacteria and viruses – some that can still reproduce. This latest work was by ...

Washington (AFP) - US President Joe Biden's administration released a new Arctic strategy on Friday as the strategically and environmentally important region suffers worsening effects from climate change and sees increased international competition. Global warming is melting Arctic ice, opening previously closed areas to navigation and creating new opportunities for countries such as the United States, Russia and China to vie for resources and influence. The situation is further complicated by the invasion of Ukraine by Russia -- a major Arctic power -- which has increased tensions between Mos...

Washington (AFP) - Rapid warming of the Arctic is likely a key driver of extreme winter weather in the United States, according to a new study that addresses a longstanding apparent contradiction in climate science and could explain events like February's cold snap in Texas. The paper, published in the journal Science, used observational data and modeling to establish a link between planetary warming linked to human activity and a phenomenon called the stratospheric polar vortex (SPV) disruption. The stratospheric polar vortex is a band of westerly winds encircling the Arctic that under normal...

Washington (AFP) - Dinosaur species large and small made the Arctic their year-round home and probably developed wintering strategies like hibernation or growing insulating feathers, according to a new study. The paper, published Thursday in the journal Current Biology, is the result of more than a decade's worth of painstaking fossil excavations, and puts to rest the notion that the ancient reptiles lived only in hotter climes. "A couple of these new sites we found in the last few years turned up something unexpected, and that is they're producing baby bones and teeth," lead author Patrick Dr...

Reykjavik (AFP) - Arctic countries on Thursday pledged to fight global warming, which is happening three times faster in the Far North, and to preserve peace in the region as its geopolitical importance rises. Accelerated global warming, untapped resources, new maritime routes opened up by retreating sea ice, and the future of local populations all topped the agenda as foreign ministers of countries bordering the Arctic gathered in Reykjavik in Iceland. "We are committed to advancing a peaceful Arctic region where cooperation prevails on climate, the environment, science and safety," US Secret...

Alexandra Land (Russie) (AFP) - "The enemy shall not pass," exclaims commander Ivan Glushchenko, standing in the glistening white snow that surrounds an ultra-modern Russian military base in the heart of the Arctic, the site of Moscow's stand-off with NATO. The growing accessibility of natural resources and navigation routes in this rapidly thawing region has attracted global competition, and Moscow's interests clash with those of several other countries, including the United States. These tensions are likely to resurface in Reykjavik Wednesday at a ministerial meeting of the Arctic Council --...
