A new study be the University of Manitoba, finds that for every degree of global warming, the open water period in the Arctic will increase by roughly one month. The study, Arctic open-water periods are projected to lengthen dramatically by 2100 – published in the Nature journal Communications Earth & Environment, notes: The shrinking of Arctic-wide…
Ice cores obtained years ago document an ominous rise of temperatures, abrupt change manifesting just within a few decades. First scientists thought this must be an error, but slowly they realize what it could mean for us today. Research into the polar ocean, found, it is getting hotter at a rate faster than even the worst…
At the end of the last ice age, geological fingerprints recorded in ocean sediments suggests glacier retreat of 50 meters a day, 18 km a year.For comparison the fastest retreating glaciers in Antarctica today are the Pope, and the Smith glacier system, retreating about 2.9 km a year. The study data was obtained in the…
Significant changes have taken place on Denman Glacier and Shackleton Ice Shelf. The floating section of the glacier experiences vigorous ice melt in contact with the ocean, which suggests the presence of Circumpolar Deep Water. However, there is no historical oceanographic data near the glacier. https://www.pnas.org/content/116/4/1095 Denman Glacier, located in East Antarctica retreated about 5…
A new study suggests that the East Antarctica Ice Sheet in the Wilkes Basin may have completely disappeared around 400,000 years ago. Currently the Wilkes Basin is only hold back by the Cook, Mertz, and the Ninnis glacier – the Cook Glacier shelf has already collapsed. There is also the Totten Glacier farther to the…
In this talk from October 2019, Eric Rignot suggests the possibility of 4 meters of sea level rise per century. Just extrapolating based on Antarctic marine glaciers retreating would yield the figure Notes a new model with results in the ballpark Notes the figure is in agreement with past sea level rise estimates Not mentioned…
It has long be debated, estimated, projected when the Arctic Ocean becomes essentially ice free, in terms of the so called Blue Ocean definition – typically defined as less than 1 million square kilometers of ice, or less than 10% of the basin. YALE: Relentless high pressure and cloud-free skies have allowed the Arctic Ocean’s sea…
It’s difficult to imagine, but currently the Netherlands is on a trajectory to be swept away by sea level rise. Previous measures are no longer sufficient enough in light of more recent knowledge. The question is not if the Netherlands will disappear below sea level, but when https://www.uu.nl/en/news/the-question-is-not-if-the-netherlands-will-disappear-below-sea-level-but-when As sea levels rise, how long until…
A Never-Before-Seen Event Is Collapsing an Ice Sheet in the Russian Arctic – Will ice stream collapse accelerate Sea Level Rise super extreme? Scientists have discovered a rare event, a collapsing ice sheet. With already multi meter sea level rise estimates from global warming, this highlighted event may accelerate trends further, with serious implications for…
