Glacier collapses in China's Xinjiang

A huge body of glacier has collapsed in China's Xinjiang, burying more than 100 cattle, crushing dozens of houses and damaging 1,000 hectares of grassland, local government said on Saturday.

New Zealand's glaciers melting at an alarming rate (video Al Jazeera)

Glaciers are one of nature's most awe-inspiring features - constantly changing as environmental conditions shift.

Disaster predicted as glaciers retreat

Since the 1950s, China's glaciers have retreated by about 7,600 square kilometers, or around 18 percent. An average of 247 square kilometers of glacial ice has disappeared every year.

Tibet's glaciers retreat. The melting glaciers will inevitably lead to ecological and environmental change.

Sea level rise quickens more than thought in threat to coasts

Sea level rise in the past two decades has accelerated faster than previously thought in a sign of climate change threatening coasts from Florida to Bangladesh, a study said today.

China confirms its southern glaciers are disappearing

By Christina Larson, Science Insider
BEIJING—Glaciers in China that are a critical source of water for drinking and irrigation in India are receding fast, according to a new comprehensive inventory. In the short term, retreating glaciers may release greater meltwater, “but it will be exhausted when glaciers disappear under a continuous warming,” says Liu Shiyin, who led the survey for the Cold and Arid Regions Environmental and Engineering Research Institute in Lanzhou.

Glaciers in northern Antarctic Peninsula melting faster than ever despite increased snowfall

An international team of researchers, led by Dr Bethan Davies, from Royal Holloway, University of London, has discovered that small glaciers that end on land around the Antarctic Peninsula are highly vulnerable to slight changes in air temperature and may be at risk of disappearing within 200 years.

Temperatures are currently rising rapidly in the Antarctic Peninsula. Because warmer air holds more moisture, the amount of snowfall has also increased. Some researchers have suggested that this may offset the melting of the glaciers, however this study found that just a small rise in air temperature increased melting so much that even large amounts of extra snowfall could not prevent glacier recession.

Iceland issues red alert after new eruption near volcano

Iceland on Sunday raised its aviation alert over its largest volcano to the highest level of red after a new eruption nearby.

The alert entails a ban on all flights below 6,000 feet (1.8 kilometers) within a radius of 10 nautical miles (18.5 kilometer) of Bardarbunga.

"All airports are open. The area has no effect on any airports," the Civil Protection Office said in a statement.

Sunday was the third time in a week that Iceland issued a red alert for aviation due to seismic activity near Bardarbunga.

Strong quakes shake Icelandic volcano

Two strong earthquakes on Sunday shook Iceland's largest volcano, which is on orange alert lowered from red one for one day amid fears of an imminent eruption, the Icelandic Met Office said.

A large explosion at the Bardarbunga volcano could signal a replay of the global travel chaos caused by the eruption of another Icelandic peak four years ago, which created a massive ash cloud across Europe.

The earthquakes were listed on the Met Office's website with intensities of 5.3 and 5.1 on the Richter scale, which makes them the strongest recorded in the region since the current seismic cycle began last week.

Iceland issues aviation alert on volcano activity (M 4.7 - ICELAND - 2014-08-23 18:33:06 UTC.....local time: 18:33)

Iceland's Meteorological Office says a subglacial eruption is underway at the Bardarbunga volcano, which has been rattled by thousands of earthquakes over the past week.

Vulcanologist Melissa Pfeffer said seismic data indicates that lava from the volcano is melting ice beneath the Vatnajokull glacier. She said it was not clear when, or if, the eruption would melt the ice and send steam and ash into the air.

Minutes earlier, Iceland raised its aviation alert for the volcano to the highest level of red on Saturday, indicating an eruption that could cause “significant emission of ash into the atmosphere.” Red is the highest alert warning on a five-point scale.

Double threat for Tibet (Climate change and human development are jeopardizing the plateau’s fragile environment.)

The plateau and its surrounding mountains cover 5 million square kilo­metres and hold the largest stock of ice outside the Arctic and Antarctic; the region is thus often referred to as the Third Pole. And like the actual poles, it is increasingly feeling the effects of climate change, but rapid development is putting it doubly at risk, the report says.

Iceland orders evacuation due to possible volcano eruption

The National Commissioner of the Icelandic Police (NCIP) announced on Tuesday that the authorities were evacuating the north of Vatnajokull to prepare against a possible eruption at Bardarbunga volcano in southeast Iceland.

The NCIP said in a statement that it has raised the Civil Protection level to Alert Phase as all roads leading into the area were closed, and the authorities in Husavik and Seydisfjordur were evacuating the area north of Vatnajokull.
A surveillance plane of the Icelandic Coast Guard has been ordered to monitor the volcano's situation.

Threat to flights as Iceland's biggest volcano rumbles

REYKJAVIK: Iceland has warned that its largest volcano is in danger of erupting, four years after millions of air travellers were grounded by a huge ash cloud from another peak.
Scientists believe the ash from an eruption at Bardarbunga could disrupt transatlantic and northern European air traffic, with floods of melting ice likely to cause serious damage to the country's infrastructure.
The Icelandic Meteorological Office raised its aviation alert to the second-highest level on Monday after four days of increasing seismic activity, signalling a heightened risk of eruption.

Climate change threatening New Zealand's glacier tourism industry

Global climate change might put an end to tourist trails over New Zealand's iconic South Island glaciers, a geography researcher warned Friday.

The multimillion-dollar glacier tourism industry was under threat with the two main glaciers, Fox and Franz Josef, in rapid retreat, said University of Canterbury researcher Dr Heather Purdie.

"The current glacial retreat is making access increasingly difficult for guided walks at Fox and Franz Josef glaciers but, simultaneously, an enlarging glacial lake at Tasman Glacier is increasing tourism opportunities," Purdie said in a statement.

Ban warns against escalation of crisis in Ukraine, saying ‘small sparks’ could ‘ignite larger flames’. - Visit to Greenland

UN, 28 March 2014 – Reiterating his strong call for a diplomatic solution to the crisis over Ukraine, United Nations Secretary-General Ban Ki-moon this evening warned the concerned parties – and the wider international community – that “at this time of heightened tensions, even small sparks can ignite larger flames of unintended consequences.”

“What started as a crisis in Ukraine, is now also a crisis over Ukraine. From the beginning, my objective has been to seek a peaceful and diplomatic solution to the crisis, in keeping with the fundamental principles of the United Nations Charter,” Mr. Ban told reporters following his briefing to the Security Council on his recent travels.

Θεαματική κατάρρευση πάγων στην Παταγονία

Στο κατάλληλο μέρος την κατάλληλη στιγμή βρέθηκε ένας ερασιτέχνης φωτογράφος, ο οποίος κατέγραψε την εντυπωσιακή κατάρρευση τμήματος ενός παγετώνα στην Παταγονία με τη φωτογραφική του μηχανή. Δεύτερος αυτόπτης μάρτυρας μαγνητοσκόπησε το συμβάν με το κινητό του τηλέφωνο και ανάρτησε το βίντεο στο Διαδίκτυο.
Σύμφωνα με το Παρατηρητήριο της Γης της NASA, ο Πέριτο Μορένο είναι ένας από τους μεγαλύτερους παγετώνες της Παταγονίας, του νοτιότερου άκρου της Νοτίου Αμερικής, καλύπτοντας έκταση 250 τετραγωνικών χιλιομέτρων! Είναι επίσης ο ένας από τους μόλις 3 παγετώνες της περιοχής που αναπτύσσονται και αποτελεί πόλο έλξης για τους τουρίστες.

Polar ice melt 'accelerating'

 
 -----
Glaciers and icebergs are believed to be melting at the fastest rate recorded in decades.
A group of scientists has discovered that polar ice is melting three times faster than it was twenty years ago.
