Scientists reclassify Humboldt glacier, also known as La Corona, after it melted faster than expected
Venezuela has lost its last remaining glacier after it shrunk so much that scientists reclassified it as an ice field.
It is thought Venezuela is the first country to have lost all its glaciers in modern times.

Standing in the shadow of Iceland’s Snæfellsjökull, – a 700,000-year-old glacier perched on a volcano and visible to half the country’s population on any given day – in 2010, Angela Rawlings was struck by an unconventional thought.
“It suddenly just came to me. What if the glacier was president?” said Rawlings. It was a seemingly unorthodox way to push forward a movement that was already swiftly advancing; Ecuador had enshrined legal rights for nature while Māori in New Zealand were working to secure legal personhood for the Whanganui River.

A leading Antarctic scientist has urged the Albanese government to pay closer attention to abrupt changes under way in the southern continent, warning they will affect Australians in ways that are little understood and research into them is drastically underfunded.
The head of the Australian Centre for Excellence in Antarctic Science, Prof Matt King, said he found it embarrassing how little was known about the local and global ramifications of changes including a historic drop in floating sea ice cover, the accelerating melting of giant ice sheets and the slowing of a deep ocean current known as the Southern Ocean overturning circulation.

Frozen daiquiri anyone? Drinking a cocktail on top of a Dubai skyscraper may seem decadent enough, but a Greenland entrepreneur wants to add ancient glacier ice scooped from the fjords to the glass, for the ultimate international thrill.
Arctic Ice harvests ice from the fjords of Greenland, and then ships them to the United Arab Emirates to sell to exclusive bars. Using glacial ice in drinks is a common practice in Greenland, and, over the years, several entrepreneurs have unsuccessfully attempted to export it. Its co-founder Malik V Rasmussen said the ice, which has been compressed over millennia, is completely without bubbles and melts more slowly than regular ice. It is also purer than the frozen mineral water usually used in Dubai’s ice cubes.

Two of the world’s few tropical glaciers, in Indonesia, are melting and their ice may vanish by 2026 or sooner as an El Niño weather pattern threatens to accelerate their demise, the country’s geophysics agency has said.
The agency, known as BMKG, has said the El Niño phenomenon could lead to the most severe dry season in Indonesia since 2019, increasing the risk of forest fires and threatening supplies of clean water.

The remains of a German mountain climber who disappeared while crossing a glacier near the Matterhorn mountain nearly 40 years ago have been discovered in melting ice.
Two climbers found the remains on 12 July while hiking along the Theodul Glacier in Zermatt, Valais, southern Switzerland, police said on Thursday.

Half the planet’s glaciers will have melted by 2100 even if humanity sticks to goals set out in the Paris climate agreement, according to research that finds the scale and impacts of glacial loss are greater than previously thought. At least half of that loss will happen in the next 30 years.
Researchers found 49% of glaciers would disappear under the most optimistic scenario of 1.5C of warming. However, if global heating continued under the current scenario of 2.7C of warming, losses would be more significant, with 68% of glaciers disappearing, according to the paper, published in Science. There would be almost no glaciers left in central Europe, western Canada and the US by the end of the next century if this happened.

The summer season was just getting into the swing in the mountain towns based around the Marmolada, the highest peak in the Italian Dolomites, when a huge mass of ice from a glacier on its north side snapped off last Sunday afternoon, causing a fatal avalanche.
Hotels, restaurants and mountain refuges were packed, and trails busy with hikers, climbers and cyclists, many flocking to the mountains in search of slightly fresher temperatures during Italy’s intense heatwave.

Twenty years ago, an area of ice thought to weigh almost 500bn tonnes dramatically broke off the Antarctic continent and shattered into thousands of icebergs into the Weddell Sea.
The 1,255-sq-mile (3,250-sq-km) Larsen B ice shelf was known to be melting fast but no one had predicted that it would take just one month for the 200-metre-thick behemoth to completely disintegrate.

Throughout the 2021 United Nations climate change conference, the Guardian will be publishing the stories of the people whose lives have been upended – sometimes devastated – by the climate breakdown.

When mountaineer Chris Hill found a backpack with an old camera in it on the Hooker Glacier – an 11km chunk of ice on New Zealand’s South Island – he was intrigued and decided to get the film inside developed.
Hooker is at the base of Aoraki (Mount Cook), in a national park of icy peaks where hundreds of climbers have died, dozens of them never to be found.

Rain has fallen on the summit of Greenland’s huge ice cap for the first time on record. Temperatures are normally well below freezing on the 3,216-metre (10,551ft) peak, and the precipitation is a stark sign of the climate crisis.
Scientists at the US National Science Foundation’s summit station saw rain falling throughout 14 August but had no gauges to measure the fall because the precipitation was so unexpected. Across Greenland, an estimated 7bn tonnes of water was released from the clouds.

Sweden’s only remaining mountaintop glacier, which until 2019 was also its highest peak, lost another two metres in height in the past year due to rising air temperatures driven by climate change, Stockholm University says.
In 2019, the south peak of the Kebnekaise massif was demoted to second in the rankings of Swedish mountains after a third of its glacier melted. Kebnekaise’s north peak, where there is no glacier, is now the highest in the Nordic country.
Continue reading...Analysis shows significant risk of cascading events even at 2C of heating, with severe long-term effects
Ice sheets and ocean currents at risk of climate tipping points can destabilise each other as the world heats up, leading to a domino effect with severe consequences for humanity, according to a risk analysis.
Tipping points occur when global heating pushes temperatures beyond a critical threshold, leading to accelerated and irreversible impacts. Some large ice sheets in Antarctica are thought to already have passed their tipping points, meaning large sea-level rises in coming centuries.
Continue reading...Scientists say ice equivalent to 1-2 metres of sea level rise is probably already doomed to melt
A significant part of the Greenland ice sheet is on the brink of a tipping point, after which accelerated melting would become inevitable even if global heating was halted, according to new research.
Rising temperatures caused by the climate crisis have already seen trillions of tonnes of Greenland’s ice pour into the ocean. Melting its ice sheet completely would eventually raise global sea level by 7 metres.

The soldiers dug the wooden barracks into a cave on the top of Mount Scorluzzo, a 3,095-metre (10,154ft) peak overlooking the Stelvio pass. For the next three-and-a-half years, the cramped, humid space was home to about 20 men from the Austro-Hungarian army as they fought against Italian troops in what became known as the White War, a battle waged across treacherous and bitterly cold Alpine terrain during the first world war.
Fought mainly in the Alps of the Lombardy region of Italy and the Dolomites in Trentino Alto-Adige, the White War was a period of history frozen in time until the 1990s, when global warming started to reveal an assortment of perfectly preserved relics – weapons, sledges, letters, diaries and, as the retreat of glaciers hastened, the bodies of soldiers.
Continue reading...More than 12,000 deaths have already been attributed to glacial lake outburst floods worldwide
An increasing number of people are being threatened by flooding caused by glacial lakes bursting, scientists have warned.
As the planet warms and glaciers recede, meltwater accumulates and forms lakes, often as a result of ice or moraine acting as a dam. Since 1990, the volume, area and number of these glacial lakes has increased by 50% globally. When these lakes become too full there is a risk that they may breach or overflow, releasing huge volumes of water and causing catastrophic flooding.

Alpine flowers could go extinct after glaciers disappear as more competitive species colonise terrain higher up the mountain, new research has warned.
Glaciers are retreating at historically unprecedented rates, exposing new land for plants to grow, which benefits delicate alpine species in the short term. However, these early pioneers – some of which are endemic – soon become endangered as more aggressive species take over, driving them out of their remaining habitat and decreasing overall biodiversity, according to the paper published in Frontiers in Ecology and Evolution.

Himalayan snow and ice is diminishing fast. Global heating is certainly playing a significant role, but now a recent study in Nature Climate Change reveals that wind-blown dust is worsening the melting effect.
Winter snowfall and spring snowmelt provide more than half of the annual freshwater needs of around 700 million people in south Asia, but over the last 30 years the overall snow mass on the high mountains of Asia, which include the Himalayas, the Hindu Kush and the Karakoram, has decreased.
