Sea level rise now menaces even a Viking bastion of uplifted land

October 17, 2022984 Views

About 1,000 years ago, a Viking woman named Ingrid built a wharf to load ships at a bay on the Swedish coast and commemorated the site with a looping runic inscription on a grey boulder. Today Ingrid’s harbour, surrounded by birch and pine trees, is high and dry, on land 5 metres (16 feet) above sea level and 20 kms (12 miles) inland from coastal Stockholm, on the Baltic Sea. Land across much of the Nordic region has been rebounding since the end of the Ice Age about 12,000 years ago, as a heavy smothering of ice up to 3 km (1.9 miles) thick melted away. That rise should make the region an unlikely candidate to suffer problems from a global rise in ocean levels as seas warm and glaciers melt - a threat for low-lying nations and coastal cities around the world, from Shanghai to Mi...

Researchers assess the dire consequences of climate change under a business-as-usual scenario There’s more bad news for planet earth if climate change continues unabated. New research published on October 11th in the open access journal PLOS Biology by researchers at the University of Hawaiʻi at Mānoa, United States reveals that, under a worst-case scenario, half of coral reef ecosystems worldwide will permanently face unsuitable conditions in just a dozen years.

As Himalayan glaciers melt, a water crisis looms in South Asia

Warmer air is thinning most of the vast mountain range’s glaciers, known as the Third Pole because they contain so much ice. The melting could have far-reaching consequences for flood risk and for water security for a billion people who rely on meltwater for their survival. Spring came early this year in the high mountains of Gilgit-Baltistan, a remote border region of Pakistan. Record temperatures in March and April hastened melting of the Shisper Glacier, creating a lake that swelled and, on May 7, burst through an ice dam. A torrent of water and debris flooded the valley below, damaging fields and houses, wrecking two power plants, and washing away parts of the main highway and a bridge connecting Pakistan and China. Pakistan’s climate change minister, Sherry Rehman, tweeted vide...

Missing snow puts famed New Zealand ski areas on precipice

New Zealand’s Tūroa ski area is usually a white wonderland at this time of year, its deep snowpack supporting its famed spring skiing. This season, it’s largely a barren moonscape, with tiny patches of snow poking out between vast fields of jagged volcanic boulders. The ski area was forced to close for the season this week, three weeks earlier than planned. Rain repeatedly washed away the snow, and the ski area’s 50 snowmaking machines proved no match against balmy temperatures. Climate change appears to be a significant factor, after New Zealand experienced its warmest winter on record — for the third year in a row. The ski slopes are almost devoid of snow at the Tūroa ski field at Mt. Ruapehu, New Zealand on Sept. 21, 2022. (AP Photo/Nick Perry) The disastrous snow season co...

Climate change likely aiding Alaskan cruise season, Norwegian Cruise CEO says

Climate change may be playing a role in extending the Alaskan cruise season, potentially opening up new revenue opportunities for the industry, Norwegian Cruise Line Holdings Chief Executive Officer Frank Del Rio said on Thursday. While climate change has warmed Alaska at more than twice the global rate, harming its fisheries and increasing the rate of wildfires, some parts of the state’s tourism have somewhat benefited from the extension of warm-weather weeks during the year. Alaskan sailings, which typically begin in mid-May and last until mid-September, are now starting as early as April and going on till October, Del Rio said during an investor day presentation, adding the company was investing more in new cruises and docks around America’s biggest state. “Alaska has not ...

Seasonal change in Antarctic ice sheet movement observed for first time

Some estimates of Antarctica’s total contribution to sea-level rise may be over- or underestimated, after researchers detected a previously unknown source of ice loss variability. The researchers, from the University of Cambridge and Austrian engineering company ENVEO, identified distinct, seasonal movements in the flow of land-based ice draining into George VI Ice Shelf – a floating platform of ice roughly the size of Wales – on the Antarctic Peninsula. Riley Glacier, Palmer Land, Antarctica. Photo: Ian Willis Using imagery from the Copernicus/European Space Agency Sentinel-1 satellites, the researchers found that the glaciers feeding the ice shelf speed up by approximately 15% during the Antarctic summer. This is the first time that such seasonal cycles have been detected on la...

Ian shows the risks and costs of living on barrier islands

When Hurricane Ian struck Florida’s Gulf Coast, it washed out the bottom level of David Muench’s home on the barrier island of Sanibel along with several cars, a Harley-Davidson and a boat. His parents’ house was among those destroyed by the storm that killed at least two people there, and the lone bridge to the crescent-shaped island collapsed, cutting off access by car to the mainland for its 6,300 residents. Hurricane Ian underscores the vulnerability of the nation’s barrier islands and the increasing costs of people living on the thin strips of land that parallel the coast. As hurricanes become more destructive, experts question whether such exposed communities can keep rebuilding in the face of climate change. In this aerial photo made in a flight provided by mediccorps.org,...

When and if an island nation fully submerges due to rising seas, what happens to the nationalities of its citizens? This and other related questions are being considered by island nations advocating for changes to international law as climate change threatens their existence. “Climate change induced sea level rise is a defining issue for many Pacific Island states and like most climate change issues, Pacific Island states have been at the forefront of challenging international law to develop in a way which is equitable and just,” said Fleur Ramsay, head of litigation and climate lead of the Pasifika Program at the Australia-based Environmental Defenders Office. Eseta Vusamu sits near the water Thursday, Sept. 29, 2022, in the village of Faleasiu on the island of Upolu in Samoa. (...

Research center in Chile’s Cape Horn serves as climate change ‘sentinel’

Located at the tip of South America, where the Pacific and Atlantic oceans meet, Cape Horn in Chile is the closest land mass to Antarctica and home to a unique ecosystem that scientists say is a natural laboratory to study climate change. Ricardo Rozzi, director of the almost-completed Cape Horn International Center (CHIC), said the area has at least 10 features - including the world's southernmost forest - which make the Cape Horn Biosphere Reserve ideal to monitor plant and animal life on a warming planet.

Worst melt year on record for Swiss glaciers

Swiss glaciers have recorded their worst melt rate since records began more than a century ago, losing 6% of their remaining volume this year or nearly double the previous record of 2003, monitoring body GLAMOS said on Wednesday. The melt was so extreme this year that bare rock that had remained buried for millenia re-emerged at one site while bodies and even a plane lost elsewhere in the Alps decades ago were recovered. Other small glaciers all but vanished.
