Greenland’s largest glacier (Jakobshavn) has quite abruptly thickened since 2016. The thickening has been so profound the ice elevations are nearly back to 2010-2011 levels. The nearby ocean has cooled ~1.5°C – a return to 1980s-era temperatures.
The world’s glaciers have not been following along with the CO2-driven catastrophic melting narrative.
For example, in a study of 50 Alaskan glaciers for the warming period between 1972-2012, researchers (McNabb and Hock, 2014) found
“…no corresponding change in the number of glaciers retreating nor do we see corresponding acceleration of retreat rates. To the contrary, many glaciers in the region have advanced…”

This aerial shot of six fat polar bears lolling around on a sand beach on the coast of the Southern Beaufort Sea, Alaska, was taken by NOAA employees in July 2019. It exemplifies the reality that bears in this subpopulation are currently abundant and healthy, negating the suggestion that numbers have continued to drop since 2006 because bears are starving.
The above picture of polar bear health is not an exception but the rule for all 31 bears recorded onshore last July, as the photos below from other locations testify. Those who would blame this abundance of bears on lack of sea ice in 2019 should note that ice retreated as early and as extensively in 2017 yet only 3 bears were spotted onshore. Results of a recent (2017-2018) population survey, which have not yet been made public, will of course not reflect conditions seen in 2019.

Posted on September 1, 2019 | Comments Off on Walruses climbing cliffs and falling off them are natural events: 1994 video from Alaska
US Fish and Wildlife officials in 1994 explain walruses falling to their deaths from a cliff at Cape Pierce in the southern Bering Sea (a haulout for adult males during the ice-free season). Explanation? Overcrowding (too many walruses)!
Hype from the Netflix/Attenborough ‘climate change is gonna destroy the world’ fearmongers earlier this year notwithstanding – or the media this summer trying to stir up climate change fever – the US Fish and Wildlife Service determined in October 2017 that the Pacific walrus is not being harmed by climate change and is not likely to be harmed within the foreseeable future (USFWS 2017). The IUCN Red List (2015) lists the Pacific walrus as ‘data deficient‘.
Large herds onshore are a sign of population health, not climate change, and walruses have come ashore in the Chukchi Sea during the ice-free season in summer and/or fall for more than 100 years (Crockford 2014; Fischbach et al. 2016; Lowrey 1985). Those are the relevant scientific facts.

The US state of Alaska, part of which lies inside the Arctic Circle, is sweltering under a heatwave, with record temperatures recorded in several areas, including its largest city.
Temperatures reached 90F (32C) in Anchorage on Thursday, shattering the city’s previous record of 85F.
The report clearly implied global warming as the cause, with several references to climate change links throughout the article.
As I pointed out at the time, the all-time record temperature for Alaska was set as long ago as 1915, when an incredible 100F was measured at Fort Yukon.
This story follows the usual BBC recipe for Arctic heatwaves:
- Record temperatures = global warming
- Hot weather is unprecedented in the Arctic. Most people would believe that temperatures of 90F simply never used to occur in the Arctic, it just sounds so unimaginable.
Unfortunately for the BBC, it turns out that the Anchorage temperature is not even a record!
I have now had time to check through the NOAA data files, and have discovered that back in June 1931, the temperature actually reached 92C at Anchorage:
