I really did not need to read that Vox, but I knew all along it was true. The evidence just keeps piling up. While still mourning the rapid deterioration of the Yukon River salmon runs, today we learn that a protected (federally listed as endangered), caribou herd in a national park in Canada has been extirpated because park managers value tourism revenue over preserving endangered species.
We do not deserve this beautiful planet.

Alaska's Salmon Are Getting Smaller

E. P. Palkovacs,, Recent declines in salmon body size impact ecosystems and fisheries, Nature Communications, 2020

As a commercial salmon fisher on the Yukon River (in Canada) since 1984, I, and all other fishers, have been acutely aware of this phenomenon since the 1980s.
Because we, both indigenous and non-indigenous fishers alike, typically had low levels of academic qualifications, our observations were resolutely discounted and disparaged by fisheries scientists for years and years.
We are still being ignored: It has always been obvious to us that the prime driver of the loss of the larger salmon has been size-selective fishing, undertaken of multiple salmon generations.
And yet, in this article, fishing is not identified as a driver because they had insufficient data.
They could have set a precedent and asked fishers.
Fishers selectively harvested the largest salmon for all the reasons that the largest salmon are identified as being important in the article.
This effect on salmon size is, in human life terms, permanent.
We have not only literally decimated the stocks, we have driven a permanent phenological change.
We could so easily have taken action, and fishers did, on multiple occasions, propose fishing methods to reverse the trend, before it was too late, but the proposals were not deemed sufficiently science based.
Unlike the scientific management that is driving the stocks to extinction.
We call it #ManagingToZero.

I mostly go to Worldometer for daily Covid stats.
I recently noticed that (to use today's figures) they have recorded 18,323,793 cases with an out come, i.e. patients either recovered or died. Of these 18 odd million people, 17,478,273 recovered and 845,520 died. In other words, 5% of casualties died. Is this the Case Fatality Rate that many have spoken of up thread? Or the Infection Fatality Rate? or something else entirely? 5% fatality seems to be much more deadly than most statistics I have heard.
Ummm, maybe this should go into the Stupid/Smart Questions thread...

Permafrost / Re: Permafrost general science thread
« on: August 28, 2020, 12:22:59 AM »
I've read a tiny bit about "retrogressive thaw slumps"  and was aware of how fast a multi-meter thick area (volume) of recent permafrost can mobilize, flowing into streams or the sea ("mud flows," we used to call them). 

The one on Peninsula Point formed as the Laurentide ice sheet was retreating, so the ground was freezing but there was loads of subsurface meltwater flowing and freezing too. it may have been up to 20 m thick at one stage.

The number and growth of thaw slumps are crazy. This study from the nearby Banks Island, showing a 60 fold increase in their numbers since the mid 80s

I have some cool pics and animation of the slumps too. I'll post them up tomorrow if I get the time. You can literally watch them developing just standing there.

We have a community science thaw slump monitoring project on the Dempster Highway- the road that leads (most of the way) to BFTV's study area.
I'd love to read the entire paper, is there a way to get it out from behind the paywall? SciHub does not have it yet.

Thanks FreeGrass, for drawing our (mine anyway) attention to this really interesting idea. I am one of the CCS sceptics, simply because I don't think most Carbon capture and storage schemes will really permanently store carbon- pumping CO2 into oil fields to wring the last drops of petroleum out is the most common method touted, with zero guarantee that the CO2 will stay down there.
So, a method that locks carbon into a solid stable form is far superior.
Will it work? Maybe!
What could go wrong? Haha! Lots, of course- I can just imagine getting the sums wrong and over achieving and sucking CO2 levels down to 180ppm.....BBR's vision of re-glaciation could even come true!

Firefighters are in short supply in California as the state continues to face hundreds of fast-spreading blazes.

The difficult job is made even harder this year by the ongoing Covid-19 pandemic. Many of the incarcerated laborers relied upon to fight fires are out of commission due to outbreaks in prisons across the state. Prisoners are crucial in the state’s fire response plan, fighting fires in exchange for wages as low as $2 per hour and reduced sentences.


Really? Americans have penal labour battalions fighting fires? Do they work in chain gangs? Or individual ball and chain set ups? Are most Americans OK with this?

The post-solstice weather pattern shows that this year the snowfalls have been occurring more thoroughly through summertime across highest elevations, and the map is supported by the Canucks and EOSDIS. There are likely substantial areas at highest elevations in NE Eurasia, the Himalayas, and the NW Rockies that retained snowcover through summer 2020.
OTOH, it appears we dodged the impending glaciation centred in Labrador/Quebec again; all the snow there seems to have melted. Phew!

It appears that Walking Hibernation was a hypothesis found to not exist.
"Using the body core temperature as a measure of metabolic activity (the more the bear was eating, the higher the active metabolism and the higher the temperature), the research team found no sudden temperature changes, which would have otherwise hinted at a bear entering the suggested state of “walking hibernation.” "
"ll evidence points to the fact that polar bears possess no special trick to help them survive lengthy periods without food. Instead, they lose weight just like any other starving mammal. To survive long-term, polar bears need a good platform of sea ice from which to hunt seals. In short: no sea ice = no polar bears."

Dear Walrus,
I'm not sure where you get your Polar bear biology.
Polar bears don't hibernate.
They actually fatten up in winter when they hunt seals through the ice.
They lose weight in summer because they cannot catch seals.
The longer the ice free season, the fewer calories they can get.
This is why there are no polar bears in California, despite there being an abundance of seals and sea lions.

IMHO, is very important to change the way we look at animals, specially about their minds.


Cybernetics explores this question as well. In my opinion, very few of the scientists have lived and worked with animals in a natural (as opposed to lab or other controlled) environment. It is obvious to those who regularly work with animals that there is no sharp difference between how human minds and other minds work. Even second order thinking (thinking about thinking) which is horribly difficult to rule in or out in animals occurs on a spectrum, as we regularly observe in people.

If they used 0 as the base line you can just imagine the usual suspects and "look over there it's a chunk of sea ice in the artic"so we are not there yet and scientists are just alarmist bullshiters

That's part of it of course, but as I recall 1M was chosen because it was reckoned that that was the threshold at which the Arctic Ocean would start to behave like an ocean rather than like a frozen pond. Wind driven Eckman pumping mixing up the layers of water, for example.
1m km2 is considered a tipping point.

My apologies everyone.
Of course the melting down of nuclear power plants, unless they were to detonate like a nuclear bomb, would not trigger a nuclear winter.

It will be interesting to see if methane concentrations decrease later this year since much of the US and Canadian fracking decreased in May and looks to be reduced through 2021 with the oil oversupply and Covid recession demand destruction.

Considering methane leaks are a feature of fracked wells, and considering that the frackers have even less free cash than usual for properly abandoning their wells, I  do not expect methane pollution to drop appreciably.

From my experience, living close to this kind of environment, I have observed the difference in break up of ponds and lake to be dependent on:
  • The thickness of the ice which is dependent on the depth of the water and the presence of ground water flow
  • The size of the water body

But mostly it depends on if there is any water flow through the pond.
 Moving water erodes/melts ice much faster than still water.

I'm guessing that the cause of this spectacular event is the active layer detaching from underlying ice rich permafrost. June is rather early for this, but possibly a rain event deepened the active layer.
I thought to place this in the permafrost thread, but considering what happens to the houses, here seems more appropriate.

There is something illogical about there all of a sudden being excess potatoes or milk etc. Presumably the net amount of food that people consume has not declined. So why the excess? Could it be that people are all cooking at home instead of eating out and that this is much more efficient and much less wasteful?

Six questions we should be asking about coronavirus
Is self-quarantining good enough?
Do quarantines work well anyway?
How would a large quarantine be implemented and enforced?
How much do we have a right to know?
Should there be better, clearer protocols for infected people?
How can taxpayers be protected from a money grab?

1/Self Quarantining post exposure or post infection is essential- it is not "good enough"
2/Yes, large quarantines work better than any other response so far.
3/Good leadership and the power of the state
4/What does "right" mean? Excellent communication and information is essential
5/ That depends on where you live... generally, there is still work to be done here. Protocols are often well worked out but poorly adopted.
6/ What? Right, you are American. Universal health care will sidestep most profiteering.

Vineyards have reached the southern city limits of Hamilton within the last 10 years, and that's a ways north of Lake Erie.
I wouldn't be surprised if the newer vineyards are even further north.

The palm trees at Port Dover and Turkey Point are a nice addition to the Beach Resorts, and I saw an ornamental banana tree in Vancouver yard last time I was out west.

The crops seem to be rushing north faster than many urbanites are aware.

Crops can move as fast as people plant them. Forests will only move north if nations embark on an all out effort to move entire ecosystems north. It would be messy. Mistakes would be made but this kind of mitigation should already be occurring.

I'm not sure that it's possible here in Canada. We've lost millions of trees to pine beetles & will lose millions more. Our tree line is constrained in part by winter insolation, & it's hard to grow trees in the dark.

More southern climes may see alpine tree lines increase in elevation but increased desertification will more than undermine those gains. I think that fires, drought and flooding will have the greatest "natural" effects on forests. If we continue burning forests and bulldozing them for agriculture & industry the natural losses will never be mitigated.

According to this research, there is another constraint on tree lines moving north. They do not identify the constraint, but I rather suspect it may have something to do with mycorrhiza- or rather their absence.

But from around 1500, hunting dramatically intensified when Europeans discovered the rich fishing grounds of Newfoundland. Within 350 years, the last great auks ever reliably seen were killed to be put in a museum, and the species was lost forever.

Even had we not hunted the Great Auk to extinction by the early 19th century, it would likely be facing the same fate now because we have so depleted the oceans of fish that most of the Great Auk's relatives are rapidly declining.

Thanks Vox
Just as with Continental Drift, or the astronomic solution to the dying off of dinosaurs, we'll have to wait until most of the doubters have died off before the new Younger Dryas Asteroid theory finds acceptance. In the meantime the evidence just keeps building.

We might get our heads around the idea that Paleo Hunters killed the last Mammoth, but imagining people with spears killing the last pride of Saber Toothed Cats, or the last pack of Dire Wolves, takes a fevered imagination.

Terry - hoping I outlive the doubters. ;)

Asteroid impacts coincident with the Younger Dryas event do not have to supersede the conventional theory that a mass outflow of fresh water from the already collapsing Laurentide ice sheet drove the temperature change.They could however have exacerbated the effect. Further, it is much more likely that the end of the Clovis culture was driven by the anthropogenic extinction of ice age mega fauna than by an asteroid- unless it was awfully, awfully big. And, mega predators did not have to be hunted or killed by humans to go extinct once their prey had been killed off. In my not entirely uneducated opinion, the denialism that resists the idea that humans caused the mass extinctions at the end of the last glaciation is similar in nature to that which resists the idea that human caused carbon emissions are changing the climate today.

Savoonga is a Yupik village on the north shore of St. Lawrence Island, just south of the Bering Strait. Its residents have made a living from the sea, and the ice, since the rising seas formed St. Lawrence Island at the end of the Pleistocene. Alert members of the forum will be aware that the Bering Sea has failed to freeze normally the past two winters. We also know that this  lack of sea ice has had ecological consequences- the ice hosts algae, which feed phytoplankton which feeds zooplankton and which sustains the extraordinarily rich marine life of the Bering Sea. Without the ice, the algae struggle and the consequences reverberate up the food chain until even the people of Savoonga face uncertain, even troubling times. The linked article is intended to part of a series that examines the effects of climate change in this exquisitely sensitive region.

500 Million Bees Died in Brazil
Things aren't looking good for bees around the world.

In the United States, beekeepers lost four in 10 of their honeybee colonies in the past year, making it the worst winter on record.

In Russia 20 regions reported mass bee deaths, with officials also warning it could mean 20% less honey being produced.

At least one million bees died in South Africa in November 2018, with fipronil being blamed.

And countries such as Canada, Mexico, Argentina and Turkey have all also reported mass die-offs of bees in the last 18 months

Bees are just the tip of the iceberg, so to speak. Domesticated honey bees are easy to monitor, and of course their loss has an economic  impact. The same poisons that are killing honey bees are almost definitely killing other bees and other insects and the flora and fauna that depends on them.
No wonder we cannot get a grip on GHGs if we cannot even see that literally spraying poisons into our environment is a bad idea.

The forum / Re: Forum Decorum
« on: August 15, 2019, 07:25:11 AM »
I think I know where the designations came from:
New ice, nilas and young ice[edit]

Nilas in Baffin Bay
New ice is a general term used for recently frozen sea water that does not yet make up solid ice. It may consist of frazil ice (plates or spicules of ice suspended in water), slush (water saturated snow), or shuga (spongy white ice lumps a few centimeters across). Other terms, such as grease ice and pancake ice, are used for ice crystal accumulations under the action of wind and waves.

Nilas designates a sea ice crust up to 10 centimetres (3.9 in) in thickness. It bends without breaking around waves and swells. Nilas can be further subdivided into dark nilas – up to 5 cm (2.0 in) in thickness and very dark, and light nilas – over 5 cm (2.0 in) in thickness and lighter in color.

Young ice is a transition stage between nilas and first-year ice, and ranges in thickness from 10 cm (3.9 in) to 30 cm (12 in), Young ice can be further subdivided into grey ice – 10 cm (3.9 in) to 15 cm (5.9 in) in thickness, and grey-white ice – 15 cm (5.9 in) to 30 cm (12 in) in thickness. Young ice is not as flexible as nilas, but tends to break under wave action. In a compression regime, it will either raft (at the grey ice stage) or ridge (at the grey-white ice stage).

First-year sea ice[edit]

Distinction between 1st year sea ice (FY), 2nd year (SY), multiyear (MY) and old ice.
First-year sea ice is ice that is thicker than young ice but has no more than one year growth. In other words, it is ice that grows in the fall and winter (after it has gone through the new ice – nilas – young ice stages and grows further) but does not survive the spring and summer months (it melts away). The thickness of this ice typically ranges from 0.3 m (0.98 ft) to 2 m (6.6 ft).[5][6][7] First-year ice may be further divided into thin (30 cm (0.98 ft) to 70 cm (2.3 ft)), medium (70 cm (2.3 ft) to 120 cm (3.9 ft)) and thick (>120 cm (3.9 ft)).[6][7]

Old sea ice[edit]
Old sea ice is sea ice that has survived at least one melting season (i.e. one summer). For this reason, this ice is generally thicker than first-year sea ice. Old ice is commonly divided into two types: second-year ice, which has survived one melting season, and multiyear ice, which has survived more than one. (In some sources,[5] old ice is more than 2-years old.) Multi-year ice is much more common in the Arctic than it is in the Antarctic.[5][8] The reason for this is that sea ice in the south drifts into warmer waters where it melts. In the Arctic, much of the sea ice is land-locked.

Which makes perfect sense!

Our agri-food systems perversely discourage ecologically beneficial behaviour, but despite this, some farmers are persisting in doing the right thing.
One caveat about No-Till farming: No-Till facilitated by RoundUp ready cops is of no help.
No-Till combined with mulching during harvest is most definitely a good thing.
"It's not the cattle, it's our management that's the problem. To concentrate them all into a huge feedlot, that's an ecological disaster."

Hjertaas said farmers tend to be traditional and slow to change, but financial incentives could go a long way to making the switch and overcome cost and uptake challenges.

I think the beef ban is a huge mistake although I have not eaten any meat or fish in 30 years.
First, animals (cattles as well) do have an important place in regenerative agriculture and they can be bred without any adverse effects on the climate or the planet in general.
Second, it is always very harmful to ban things. Economic incentives are always better (see the historic example of taxes on alcohol vs. total abolition; or the current insane war on drugs). Create a carbon tax, or even a beef tax if you will but do not ban.
Yes, livestock can have an important place in regenerative agriculture. However, the vast majority of meat consumed in the developed world plays no role in regenerative agriculture, quite the contrary.
Yes, taxes designed to shift behaviour away from harmful practices is a preferred method over regulation, usually. However, Canada's carbon tax specifically exempts agriculture....
