A linear trend fit onto a naturally cyclical physical system is ridiculous.

So, here’s a crude hand-drawn curve to their product.  Different perspective.

Zoos abrogate their position of trust by misleading the public about polar bears

polarbearscience

Since at least 2007, zoos around the world have proudly partnered with climate change activist organization Polar Bears International to ‘educate’ the public about the plight of polar bears. Although contrary to all expectations, polar bear numbers have increased slightly since the abrupt decline of sea ice in 2007 yet zoos are still promoting the false message that polar bears have already been gravely harmed by lack of sea ice.

CTV News on pb sightings Labrador as climate change warning

A news clip that aired on Canadian television in April 2019 was ostensibly about recent sightings of polar bears in Labrador (which I discussed here). But it digressed rapidly into a baseless diatribe about polar bears as victims of climate change, delivered by an animal keeper from the Toronto Zoo presented as an ‘expert’ on this topic.

See it here (about 4 minutes long).

And while I have no doubt that Toronto Zoo curator Maria Frankie is indeed…

Video exposé of the groundless Netflix bid to elevate walrus to climate change icon

polarbearscience

Last month, Netflix and WWF released a collaborative nature documentary that contained an egregiously: that Pacific walrus are being forced ashore by global warming where they suffer staggering population losses. But this is a story the film producers and WWF concocted for their own purposes, not a statement supported by scientific fact.

Video title screen

Over the last month, pointed questions have been asked about what really happened in Siberia while the film crew was there – and what didn’t. Scientific documents support the conclusion that Pacific walrus are currently thriving, have not been harmed by recent sea ice losses, and are not expected to be harmed in the foreseeable future, see here, here, here, and here.  This new video explains it all.

Mighty Greenland glacier slams on brakes

Tallbloke's Talkshop

Jakobshavn glacier, West Greenland [image credit: Wikipedia]
Even the climate alarm oriented BBC has finally had to admit the inconvenient truth about Greenland’s largest glacier. Instead of dropping in height by 20m. a year, it’s now thickening by 20m. a year. This isn’t supposed to happen when one of the stock phrases of the fearmongering media is ‘the rapidly melting Arctic’. Of course logic says that since glaciers can grow naturally they can also retreat naturally, despite attempts to blame humans.

European satellites have detailed the abrupt change in behaviour of one of Greenland’s most important glaciers, says BBC News.

In the 2000s, Jakobshavn Isbrae was the fastest flowing ice stream on the island, travelling at 17km a year.

As it sped to the ocean, its front end also retreated and thinned, dropping in height by as much as 20m year.

But now it’s all change. Jakobshavn is travelling…

Polar bear habitat update for early spring shows no influence of a CO2 control knob

polarbearscience

The primary feeding period for polar bears is rapidly drawing to a close in much of the Arctic, although it may continue for another few weeks in the farthest north. Mating is pretty much over as well, which means the polar bears’ need for abundant sea ice is declining even more rapidly than the ice does itself at this time of year.

Walking bear shutterstock_329214941_web size

Despite the fact that CO2 levels have now reached 415 ppm (see tweet below), sea ice is still pretty much as it was in 2006 when CO2 was about 385 ppm. In other words, the state of sea ice at this time of year – just over 12 million kilometres squared in 2006 and in 2019 – shows no correlation with rising CO2 levels. There is also not a hint of imminent catastrophe for polar bears anywhere within their range, despite the hand-wringing messages from conservation fear-mongers

Stop lying to children about dying polar bears as a way to achieve action on climate change

polarbearscience

The heartbreaking story of dying polar bears, told for more than a decade now, was meant to get kids on board the global warming action train. It worked a treat – except that it was never true. The lie gave sensitive children nightmares and turned others into political activists full of groundless outrage who now pointlessly rant in the streets.

BBC video screencap with Thunberg video quoting starving pb images_23 April 2019

As the established icon of climate change and Arctic habitats, polar bears have been given centre stage in the climate change narrative presented to young children and their teachers. But the distressing tale of polar bears on the brink of extinction – dying for our fossil fuel sins – was never true, as I show in point form below. Polar bear lies form the foundation of the baseless political activism of Greta Thunberg that other youngsters have since emulated.

Here are some of the false ‘facts’ children…

Melting Permafrost ‘Crisis’ Debunked By Historical Record

PA Pundits - International

From the team at CFACT ~

Climate alarmists are resuscitating an old scare, claiming melting permafrost caused by modest global warming will accelerate the warming, thus creating rapid and runaway global warming.  Objective historical data, however, conclusively debunk the scare.

An article in the April 30 edition of Nature claims, “Permafrost collapse is accelerating carbon release. The sudden collapse of thawing soils in the Arctic might double the warming from greenhouse gases released from tundra.” As a result, alarmists claim, global warming will continue to accelerate and may be irreversible absent dramatic reductions in greenhouse gas emissions.

Alarmists are piling on in response to the article.

“Carbon released into the atmosphere by the increasing loss of Arctic permafrost, combined with higher solar absorption by the Earth’s surface due to the melting of sea ice and land snow, will accelerate climate change,” states a EurekaAlert press release from Lancaster University.

A New 200‐year Spatial Reconstruction of West Antarctic Surface Mass Balance

Reblogged from Watts Up With That:

Antarctica consisted of a large Eastern ice sheet, a smaller Western ice sheet and the Antarctic peninsula. The Eastern ice sheet has been slightly gaining ice from 1992, but the Western ice sheet mass trend is more uncertain.

A new paper published in Geophysical Research: Atmospheres,  presents a reconstruction of the surface mass balance (SMB) over the West Antarctic Ice Sheet (WAIS) spanning 1800-2010. The study is based on ice core records combined with a European reanalysis model and a regional climate model.

The results show a significant negative trend of -1.9 ± 2.2 Gt/yr over the WAIS during the 19th century but a significant positive trend of 5.4 ± 2.9 Gt/yr between 1900 and 2010. In contrast, the Antarctic Peninsula (AP) shows opposite SMB trends to the WAIS trends with different signs in the 19th and 20th centuries. The study compared the trends to large-scale atmospheric oscillations. The SMB in the AP and WAIS are significantly correlated with the Southern Annular Mode (the north–south movement of the westerly wind belt that circles Antarctica), but the correlations are unstable.

Abstract

High‐spatial resolution surface mass balance (SMB) over the West Antarctic Ice Sheet (WAIS) spanning 1800‐2010 is reconstructed by means of ice core records combined with the outputs of the European Centre for Medium‐range Weather Forecasts “Interim” reanalysis (ERA‐Interim) and the latest polar version of the Regional Atmospheric Climate Model (RACMO2.3p2). The reconstruction reveals a significant negative trend (‐1.9 ± 2.2 Gt yr‐1 decade‐1) in the SMB over the entire WAIS during the 19th century, but a statistically significant positive trend of 5.4 ± 2.9 Gt yr‐1 decade‐1 between 1900 and 2010, in contrast to insignificant WAIS SMB changes during the 20th century reported earlier. At regional scales, the Antarctic Peninsula (AP) and western WAIS show opposite SMB trends, with different signs in the 19th and 20th centuries. The annual resolution reconstruction allows us to examine the relationships between SMB and large‐scale atmospheric oscillations. Although SMB over the AP and western WAIS correlates significantly with the Southern Annular Mode (SAM) due to the influence of the Amundsen Sea Low (ASL) and El Niño/Southern Oscillation (ENSO) during 1800‐2010, the significant correlations are temporally unstable, associated with the phase of SAM, ENSO and the Pacific decadal oscillation (PDO). In addition, the two climate modes seem to contribute little to variability in SMB over the whole WAIS on decadal‐centennial time scales. This new reconstruction also serves to identify unreliable precipitation trends in ERA‐Interim, and thus has potential for assessing the skill of other reanalyses or climate models to capture precipitation trends and variability.

More starving polar bear nonsense from National Geographic & a better video to watch

polarbearscience

This time National Geographic’s ‘Hostile Planet’ series laughably claims a fat polar bear that’s caught a beluga calf off the coast of Western Hudson Bay has been saved from starvation! The message: here is a prime example of climate change pushing a species to its limit. This is nonsense, of course: polar bears hunting beluga whales from rocks has nothing to do with climate change or desperately hungry bears. More importantly, there is a much better video of the action that is both more informative and truthful.
