Arctic Ice Thickness Measured From Buoys
Guest Post by Steven Goddard The Catlin Arctic Survey has generated quite a bit of discussion, more because of the difficulties they have faced than because of the scientific merit…
Arctic Snow Depth, Ice Thickness, and Volume From ICESat-2 and CryoSat-2: 2018–2021
“We weren’t really expecting to see this decline, for the ice to be this much thinner in just three short years,” said lead study author Sahra Kacimi, a polar scientist…
NASA’s ICESat-2 Measures Arctic Ocean’s Sea Ice Thickness, Snow Cover
From NASA May 14, 2020 Arctic sea ice helps keep Earth cool, as its bright surface reflects the Sun’s energy back into space. Each year scientists use multiple satellites and…
Wegener Institute continues Arctic Sea Ice flyovers to gauge thickness
Via press release. Is the ice in the Arctic Ocean getting thinner and thinner? Research aircraft Polar 5 measures thickness of sea ice north of Greenland Bremerhaven, 20th August 2010.…
Hudson Bay polar bears now considered most likely to survive future sea ice loss
Over the last 10 years, Hudson Bay polar bears have morphed from being the “most at risk” across the Arctic to the “least at risk.” Who would have thought?
Arctic “Just-So Stories”: Bad Science by Climate Alarmists
by Jim Steele The Arctic Ocean was nick-named the “upside down Ocean” by Fridtjof Nansen. Nansen was a famous Norwegian zoologists, oceanographer, and Arctic explorer as well as winner of…
Polar bear sea ice habitat update at 15 November & problem bears in Western Hudson Bay
Abundant polar bear habitat this fall across the Arctic so far, with only Hudson Bay sea ice formation a bit behind schedule.
Arctic sea ice: the canary in the coal mine
More honest reporting is required from media outlets, climate scientists and government bodies about the true nature of change, good news as well as bad, instead of highly selective reporting…
New evidence that polar bears survived 1,600 years of ice-free summers in the early Holocene
From Polar Bear Science Susan Crockford New evidence indicates that Arctic areas with the thickest ice today probably melted out every year during the summer for about 1,600 years during the…
Polar Bear Sea Ice Habitat Near the End of Arctic Spring 2023
From Polar Bear Science Susan Crockford Arctic sea ice is beginning to melt and the end of spring is drawing near. Mating season is over for polar bears as is the gorging…
Antarctic Ice Shelves Growing
Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade, whereas the steady-state approach would estimate substantial ice loss over the same period, demonstrating…
Winter sea ice habitat for polar bears still abundant enough to sustain a thriving species
The slight decline since 1979 has so far been no cause for concern to polar bears, who are thriving.
Record of Antarctic Ice Sheet Response to Climate Cycles Found in Rock Samples
“Antarctica has these interesting brines with no carbon in them, because it all precipitated out earlier, so when those brines are isolated from other sources of water they form opal,”…
Arctic Sea Ice Still Quite Abundant for Early Summer
Forget about whether the numbers are below or above some short-term average, there is no catastrophe in the making for marine mammals in the Arctic at this time.
Sea ice average for March is the metric used to compare to previous winters
Overall, nothing spectacular in terms of change compared to last few years: still lots of ice for polar bears to hunt upon for newborn seals, which they will be doing…
Good News For Polar Bears And Seals: New Study Finds Multiyear Arctic Sea Ice Is Getting Thinner
The fact that multiyear sea ice got thinner between 2018 and 2021 as documented by a new study, is ultimately good news for polar bears: less multiyear ice compared to first year ice…
Mid-winter polar bear sea ice habitat is abundant & within range of long-term average
This is a tough time for polar bears, many of which will be finding it hard to find seals to eat, as newborn seals won’t be an available food resource…
Ice Ages, Feedback Diagrams, and Climate Triggers
As well defined turning points in response and a limit-cycle of operation are long established characteristics of relay control systems, I submit that Earth’s climate regulation is non-linear in much…
Chukchi Sea ice that didn’t melt this summer is now 2+m thick between Wrangel Island and the shore
Thick multiyear ice between Wrangel Island and the shore is now more than 2m thick, potentially impacting fall feeding for bears that routinely summer on Wrangel or the north coast of Chukotka.
Antarctica wasn’t quite as cold during the last ice age as previously thought
An international team of scientists, led by Oregon State University’s Christo Buizert, has found that while parts of Antarctica were as cold as 10 degrees below current temperatures, temperatures over…
The temperature–CO2 climate connection: an epistemological reappraisal of ice-core messages

The CO2 Shift; Ice Age to Gas Age
Guest Post by Renee Hannon IntroductionThis post examines CO2 data collected from Antarctic ice cores and compares CO2 measurements in both ice age and gas age. The age of trapped…
