Polar bear habitat update: open water primarily due to winds pushing pack ice

polarbearscience

Here is a look at what polar bear habitat looks like this year at the end of May compared to previous years. It helps put any predictions of impending doom into perspective.

This is the time year when declining sea ice gets some people all worked up. However, declining ice is normal at this time of year and there is always variation in where the most open water appears first. At this time of year, there isn’t much ice ‘melt’ going on. Rather, what we are seeing is the opening up of shore leads and polynyas by winds.

This year, as usual, open water increases with the expansion of persistent polynyas due to winds and currents. These areas increase the extent of ice edges and provide polar bears with more hunting habitat (because seals congregate near open water). This year, there is…

Photographer’s claims that Inuit hunting is unsustainable are not supported

polarbearscience

A campaign by an anti-hunting Norwegian photographer to destroy the market for legally-hunted polar bears in Canada makes a few disturbingly false claims and an article at National Geographic in which he is quoted further distorts the picture of polar bear conservation. I understand that some people object to hunting and wish more people felt like they do – but this sort of argument is unlikely to sway any but the most gullible.

Norwegian photographer Ole Liodden apparently has a master’s degree in “nature management and environmental policy“. He takes fabulous polar bear pictures (I purchased one of them, above, for the cover of my novel, EATEN) but his crusade to ban hunting and trade in polar bear products world-wide has lead him to misrepresent essential facts, which is no way to win an argument. A National Geographic writer and several polar bear specialists have provided additional…

Climate Out of Control

Science Matters

Coors Baseball Field, Denver, Colorado, April 29, 2019

Frank Miele writes at Real Politics Climate Is Unpredictable, Weather You Like It or Not!
Excerpts in italics with my bolds.

They say all politics is local; so is all weather.

So on behalf of my fellow Westerners, I have to ask: What’s up with all this cold weather? It may not be a crisis yet, but in the two weeks leading up to Memorial Day — the traditional start of summer activities — much of the country has been donning sweaters and turning up the heat.

I know, I know. Weather is not climate, and you can’t generalize from anecdotal evidence of localized weather conditions to a unified theory of thermal dynamics, but isn’t that exactly what the climate alarmists have done, on a larger scale, for the past 25 years?

Haven’t we been brainwashed by political scientists (oops! I mean…

Climate Models Have Been Predicting Too Much Warming

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

John Christy has a new paper out about climate models are predicting too much warming:

https://www.thegwpf.org/climate-models-have-been-predicting-too-much-warming/

Below is the GWPF press release:

A leading climatologist has said that the computer simulations that are used to predict global warming are failing on a key measure of the climate today, and cannot be trusted.

Speaking to a meeting in the Palace of Westminster in London, Professor John Christy of the University of Alabama in Huntsville, told MPs and peers that almost all climate models have predicted rapid warming at high altitudes in the tropics:

A similar discrepancy between empirical measurements and computer predictions has been confirmed at the global level:

And Dr Christy says that lessons are not being learned:

“An early look at some of the latest generation of climate models reveals they are predicting even faster warming. This is simply not credible.”

A paper outlining Dr Christy’s…

Models Wrong About the Past Produce Unbelievable Futures

Science Matters

Models vs. Observations. Christy and McKitrick (2018) Figure 3

The title of this post is the theme driven home by Patrick J. Michaels in his critique of the most recent US National Climate Assessment (NA4). The failure of General Circulation Models (GCMs) is the focal point of his presentation February 14, 2018. Comments on the Fourth National Climate Assessment. Excerpts in italics with my bolds.

NA4 uses a flawed ensemble of models that dramatically overforecast warming of the lower troposphere, with even larger errors in the upper tropical troposphere. The model ensemble also could not accommodate the “pause” or “slowdown” in warming between the two large El Niños of 1997-8 and 2015-6. The distribution of warming rates within the CMIP5 ensemble is not a true indication of a statistical range of prospective warming, as it is a collection of systematic errors. Despite a glib statement about this Assessment fulfilling…

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.

The Guardian officially goes full climate alarmist language

Reblogged from Watts Up With That:

The Guardian’s editor has just issued this new guidance to all staff on language to use when writing about climate change and the environment…and it is full-on alarmism. No holding back punches now, because it’s a crisis, so let’s start writing like one! Josh helps us understand the real message.

Josh has interpreted this new policy:

James Delingpole notes:


There is, in essence, no such thing is a ‘climate science denier’ because not even the most ardent sceptic denies the existence of ‘climate science’.

Even more problematic is that use of the word ‘denier’, which implicitly invokes the Holocaust – and in doing so, weirdly and irresponsibly puts ‘being sceptical about anthropogenic global warming’ in the same category as ‘denying that Hitler murdered six million Jews.’

In recent years, climate alarmists have tried to backtrack on the origins of the ‘denier’ slur by pretending that they never intended to invoke Holocaust denial.

But here is Guardian environment journalist George Monbiot writing in 2006:

Almost everywhere, climate change denial now looks as stupid and as unacceptable as Holocaust denial.

Maybe Ms Viner should pay more attention to Thomas Sowell on this subject:

The next time someone talks about “climate change deniers,” ask them to name one — and tell you just where specifically you can find their words, declaring that climates do not change. You can bet the rent money that they cannot tell you.

Why all this talk about these mythical creatures called “climate change deniers”? Because there are some meteorologists and other scientists who refuse to join the stampede toward drastic economic changes to prevent what others say will be catastrophic levels of “global warming.”

There are scientists on both sides of that issue. Presumably the issue could be debated on the basis of evidence and analysis. But this has become a political crusade, and political issues tend to be settled by political means, of which demonizing the opposition with catchwords is one.

Sowell’s point is well made – and goes to the heart of what is wrong with the Guardian‘s new lexicon for its climate change reportage.

The Guardian is tacitly admitting that this is not an argument it is capable of winning on the science or indeed the facts. Therefore, it has decided to ramp up the rhetoric instead.

Our Urban “Climate Crisis”

Reblogged from Watts Up With That:

What’s Natural

Our Urban “Climate Crisis”

clip_image002

Based on a globally averaged statistic, some scientists and several politicians claim we are facing a climate crisis. Although it’s wise to think globally, organisms are never affected by global averages. Never! Organisms only respond to local conditions. Always! Given that weather stations around the globe only record local conditions, it is important to understand over one third of the earth’s weather stations report a cooling trend (i.e. Fig 4 below ) Cooling trends have various local and regional causes, but clearly, areas with cooling trends are not facing a “warming climate crisis”. Unfortunately, by averaging cooling and warming trends, the local factors affecting varied trends have been obscured.

It is well known as human populations grow, landscapes lose increasing amounts of natural vegetation, experience a loss of soil moisture and are increasingly covered by heat absorbing pavement and structures. All those factors raise temperatures so that a city’s downtown area can be 10°F higher than nearby rural areas. Despite urban areas representing less than 3% of the USA’s land surface, 82% of our weather stations are located in urbanized areas. This prompts critical thinkers to ask, “have warmer urbanized landscapes biased the globally averaged temperature?” (Arctic warming also biases the global average, but that dynamic must await a future article.)

clip_image004

Satellite data reveal that in forested areas the maximum surface temperatures are 36°F cooler than in grassy areas, and grassy areas’ maximum surface temperatures can be 36°F cooler than the unvegetated surfaces of deserts and cities. To appreciate the warming effects of altered landscapes, walk barefoot across a cool grassy lawn on a warm sunny day and then step onto a burning asphalt roadway.

In natural areas like Yosemite National Park, maximum air temperatures are cooler now than during the 1930s. In less densely populated and more heavily forested California, maximum air temperatures across the northern two thirds of the state have not exceeded temperatures of the 1930s. In contrast, recently urbanized communities in China report rapid warming of 3°F to 9°F in just 10 years, associated with the loss of vegetation.

clip_image006

Although altered urban landscapes undeniably raise local temperatures, some climate researchers suggest warmer urban temperatures do not bias the globally averaged warming trend. They argue warming trends in rural areas are similar to urbanized areas. So, they theorize a warmer global temperature is simply the result of a stronger greenhouse effect. However, such studies failed to analyze how changes in vegetation and wetness can similarly raise temperatures in both rural and urban areas. For example, researchers reported overgrazing had raised grassland temperatures 7°F higher compared to grassland that had not been grazed. Heat from asphalt will increase temperatures at rural weather stations just as readily as urban stations.

To truly determine the effects of climate change on natural habitats requires observing trends from tree ring data obtained from mostly pristine landscapes. Instrumental data are overwhelmingly measured in disturbed urbanized areas. Thus, the difference between instrumental and tree ring temperature trends can illustrate to what degree landscapes changes have biased natural temperature trends. And those trends are strikingly different!

The latest reconstructions of summer temperature trends from the best tree ring data suggest the warmest 30-year period happened between 1927 and 1956. After 1956, tree rings recorded a period of cooling that lowered global temperatures by over 1°F. In contrast, although tree rings and instrumental temperatures agreed up to 1950, the instrumental temperature trend, as presented in NASA graphs, suggests a temperature plateau from 1950 to 1970 and little or no cooling. So, are these contrasting trends the result of an increased urban warming effect offsetting natural cooling?

clip_image008

After decades of cooling, tree ring data recorded a global warming trend but with temperatures just now reaching a warmth that approaches the 1930s and 40s. In contrast, instrumental data suggests global temperatures have risen by more than 1°F above the 1940s. Some suggest tree rings have suddenly become insensitive to recent warmth? But the different warming trends are again better explained by a growing loss of vegetation and increasing areas covered by asphalt affecting temperatures measured by thermometers compared with temperatures determined from tree ring data in natural habitats.

Humans are increasingly inhabiting urban environments with 66% of humans projected to inhabit urban areas by 2030. High population densities typically reduce cooling vegetation, reduce wetlands and soil moisture, and increase landscape areas covered by heat retaining pavements. Thus, we should expect trends biased from urbanized landscapes to continue to rise. But there is a real solution to this “urban climate crisis.” It requires increasing vegetation, creating more parks and greenbelts, restoring wetlands and streams, and reducing heat absorbing pavements and roofs. Reducing CO2 concentrations will not reduce stifling urban temperatures.

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.
