Surprising sea ice thickness across the Arctic is good news for polar bears

From Polar Bear Science Posted on May 27, 2021 This year near the end of May the distribution of thickest sea ice (3.5-5m/11.5-16.4 ft – or more) is a bit surprising,…

Landmark study casts doubt on controversial theory linking melting Arctic to severe winter weather

Every time severe winter weather strikes the United States or Europe, reporters are fond of saying that global warming may be to blame. The paradox goes like this: As Arctic…

Unexpected ice

But observations show that ice extent in the Arctic has shrunk faster than models predicted, and in the Antarctic it has been growing slightly. Researchers are looking much closer at…

Global Ice Story: What they don’t tell you

The Arctic includes the Arctic Ocean, Greenland, Iceland, and part of Siberia and northern Alaska. Because of the absence of any land mass in the Arctic Ocean, most of area…

Sea Ice Slows Ships In North China Ports

Chinese ports and marine safety authorities are on high alert as an expansion of sea ice makes it tougher for ships to berth and discharge at key energy product import…

Nares Strait Ice Arches

Both 2007 and 2019 were identical in having no arches formed. Whilst 2017 and 2018 were comparable to 2008. It is not statistically possible to draw significance from such a…

Researchers discover a new tool for reconstructing ancient sea ice

In a study published in Nature Communications, the researchers show that an organic molecule often found in high-latitude ocean sediments, known as tetra-unsaturated alkenone (C37:4), is produced by one or…

Claim: Scientists find the error source of a sea-ice model varies with the season

To address the issue of error source identification, Prof. Fei Zheng and his team from the Institute of Atmospheric Physics at the Chinese Academy of Sciences, evaluated the sea-ice simulations…

Claim: The climate changed rapidly alongside sea ice decline in the north

Researchers from the Niels Bohr Institute, University of Copenhagen have, in collaboration with Norwegian researchers in the ERC Synergy project, ICE2ICE, shown that abrupt climate change occurred as a result…

“Where’s the sea ice?” Right where it’s been for most of the Holocene.

Guest “geological perspective” by David Middleton This is sort of a sequel yesterday’s post: Where’s the sea ice? 3 reasons the Arctic freeze is unseasonably late and why it matters.…

Where’s the sea ice? 3 reasons the Arctic freeze is unseasonably late and why it matters

I’ve watched the region’s transformations since the 1980s as an Arctic climate scientist and, since 2008, as director of the National Snow and Ice Data Center. I can tell you,…

On noes! Antarctic sea ice may not cap carbon emissions as much as previously thought

From the “that darned sea ice is messing up our model” department and MIT News. Study suggests sea ice blocks the flow of carbon both into and out of the…

Arctic ocean moorings shed light on winter sea ice loss

The eastern Arctic Ocean’s winter ice grew less than half as much as normal during the past decade, due to the growing influence of heat from the ocean’s interior, researchers…

Claim: Past evidence supports complete loss of Arctic sea-ice by 2035

A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035.

A snapshot of melting Arctic sea ice during the summer of 2018

A study appearing July 29 in the journal Heliyon details the changes that occurred in the Arctic in September of 2018, a year when nearly 10 million kilometers of sea…

10 fallacies about Arctic sea ice & polar bear survival refute misleading ‘facts’

Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago. But critical…

Study: Extensive Sea Ice Creates Hardship for Penguins

Who could have predicted that extensive sea ice conditions which make it harder to get to food would make life difficult for penguin populations?

Video: How simple math can help predict the melting of sea ice

Anurag Papolu, The Conversation To better predict climate change, scientists need accurate models which predict the behavior of many natural processes. One of these is the melting of arctic sea…

Antarctic sea-ice models improve for the next IPCC report

University of Washington The world of climate modeling is complex, requiring an enormous amount of coordination and collaboration to produce. Models feed on mountains of different inputs to run simulations…
