Cascading Consequences of the Loss of Arctic Sea Ice

“Losing the remaining Arctic sea ice and its ability to reflect incoming solar energy back to space would be equivalent to adding one trillion tons of CO2 to the atmosphere, on top of the 2.4 trillion tons emitted since the Industrial Age, according to current and former researchers from Scripps Institution of Oceanography at the University of California San Diego.”

“At current rates, this roughly equates to 25 years of global CO2 emissions.”

Research Highlight: Loss of Arctic’s Reflective Sea Ice Will Advance Global Warming by 25 Years  

“Algae that live in and under the sea ice play a much greater role for the Arctic food web than previously assumed. In a new study, biologists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research showed that not only animals that live directly under the ice thrive on carbon produced by so-called ice algae. Even species that mostly live at greater depth depend to a large extent on carbon from these algae. This also means that the decline of the Arctic sea ice may have far-reaching consequences for the entire food web of the Arctic Ocean. Their results have been published online now in the journal Limnology & Oceanography.”
“We now know that ice algae play a much more important role for the pelagic food web than previously assumed. This finding also means, however, that the decline of the ice could have a more profound impact on Arctic marine animals, including fish, seals and ultimately also polar bears, than hitherto suspected,” says Doreen Kohlbach.”

“Experts estimate the washed-up whales represent just 10% of the total number of the dead, with the rest sinking into the sea unnoticed by humans.”
“At least 81 gray whale corpses have washed ashore in California, Oregon, Washington and Alaska since Jan. 1. If tallies from Mexico and Canada are added, the number of stranded gray whales reaches about 160 and counting, said Michael Milstein, spokesman for NOAA Fisheries.”
Thousands of whales are dying. Scientists have run out of public beaches for the carcasses to rot

In the August episode of Nature Bats Last our guest Dr Andrew Glikson discussed his recent work titled: Beyond Climate Tipping Points: Greenhouse Gas Levels Exceed the Stability Limit of the Greenland and Antarctic Ice Sheets.
The pace of global warming has been grossly underestimated. As the world keeps increasing its carbon emissions rising in 2018 to a record 33.1 billion ton COper year, the atmospheric greenhouse gas level has now exceeded 560 ppm (parts per million) CO2equivalent, namely when methane and nitric oxide are included. This level surpasses the stability threshold of the Greenland and Antarctic ice sheets. The term “climate change“ is thus no longer appropriate, since what is happening in the atmosphere-ocean system, accelerating over the last 70 years or so, is an abrupt calamity on a geological dimension threatening nature and civilization. Ignoring what the science says, the powers-that-be are presiding over the sixth mass extinction of species, including humanity.”  

“As conveyed by leading scientists “Climate change is now reaching the end-game, where very soon humanity must choose between taking unprecedented action or accepting that it has been left too late and bear the consequences”

“Black carbon particles from  Siberian forest fires, fall down to the arctic ice. As these particles are black, they absorb sunlight and can accelerate ice melt if found in high enough concentrations. Our graphic shows black carbon concentrations, where high values can be seen emerging from the Siberian forest fires, circulating into the polar circle.”

The marine food web isn’t going to collapse, it is collapsing, now, live and direct.
The dominant culture and the corporate media are pretending to cover the unraveling of the biosphere but what they aren’t telling you about  is the rapidity of the collapse and how the domino effect of crossing these tipping points triggers cascading consequences.
I’ll be surprised if industrial civilisation survives an ice free Arctic summer and we might be only a year or two away from that eventuality.
One final comment I would make about the impending ice free Arctic sea is that we don’t need to have crossed the official definition of an Ice Free Arctic  to see the 50 gigatonne methane discharge from the clathrates as hypothesised by Dr Natalia Shakova et al. That could burst forth at any moment.
John Doyle thinks we will see a 10C temperature rise in the coming decades;

Next months guest on Nature Bats Last is Arthur Keller. We will be discussing his presentation titled “Collapse: The Only Realistic Scenario”. That episode can be found after broadcast at the Nature Bats Last archive at PRN.FM

Good luck everyone, we are sure going to need it.

I'm an anti-imperialist, environmental activist and blue ocean sailor, who is passionate about the earth and all it's inhabitants without favour. Brace for imminent impact as we bare witness to the non-linear unraveling of the biosphere and habitability disappearing for most if not all complex life on the only habitable planet we know of. To quote President Niinistö in North Russia: ‘If We Lose the Arctic, We Lose the World’. Folks we have lost the Arctic.

    A new study shows just how quickly the world’s cryosphere is shrinking
    More than 102,000 square kilometers of frozen areas were lost in the Northern Hemisphere from 1979 to 2016.

    Arctic sea ice fell to its lowest extent on record for this time of year on July 5, even though the spring had so far been relatively cool and stormy — conditions that, in the past, would have protected the ice.
    Three new studies help explain why. One found that increasing air temperatures and intrusion of warm water from the North Atlantic into the Barents and Kara Seas — a climate change-driven process known as Atlantification — are overpowering the ice’s ability to regrow in winter.
    Another study found that sea ice in coastal areas may be thinning at up to twice the pace previously thought. In three coastal seas — Laptev, Kara, and Chukchi — the rate of coastal ice decline increased by 70%, 98%, and 110% respectively when compared to earlier models.
    A third study found accelerated sea ice loss in the Wandel Sea, pointing to a possible assault by global warming on the Arctic’s Last Ice Area — a last bastion of multi-year sea ice which stretches from Greenland along the Canadian Arctic Archipelago. Combined, this research shows Arctic ice may be in worse trouble than thought.

  3. As soon as the Gulf Stream completely collapses due to the ongoing massive infusion of fresh water from the melting lump of ice known as Greenland, is it possible that this ice loss could reverse itself as Northern Europe temperatures drop? Even if only temporary? Or will the heat grow so quickly that the temperatures won’t lower as much as previously expected? As the metric used didn’t predict such intense heating in such a short period of time,

    I wonder if anything is alive on Venus hidden by the clouds from our cameras and telescopes? Could be as life is adaptable.

    Of course since our planet isn’t going to stop overheating anytime soon as I don’t see any of the acknowledged leaders of worldwide power that are truly shifting what they do; politics as usual and drill/cut/mine seems to be the only response everywhere except for more very expensive ad campaigns and a few crumbs thrown to identity politics….

    And that 30 year lag time concept could really be a bitch. Unless the methane bottle pops its cork of course. I haven’t read anything from Natalia Shakova lately. Nobody wants to read her research because it’s too scary???

    Weather:

    It hasn’t been below 90F/33C since June 18th. It was 100F/38C again yesterday after two days of low 90s. I’m not sure it was the intense fire smoke-filled atmosphere cutting it but it was 92’F at 10am this morning.

    Here’s a strange fact. On my calendar it says 6May was 85F which is fifteen degrees above normal. On 7May it was 51F which is twelve below normal. On 1Jan it was raining and was in the 40s for a few days….then again on the 14 & 15th. It has been obviously getting more and more weird here for a number of years.

    I’ve got an hour before I go check the thermometer but it’s really smoky/hazy outside with a blurry sun shining down tinted red sunlight. ‘Unhealthy air alert’ of course. I just so enjoy the concept of DON’T BREATHE TODAY! I’m now down to eighteen dust mask-style N95s, and two respirators with exhale valves. It’s pretty bad here, Kevin, but at least it is still much lower temps at night and the down-canyon breeze has started back up after dark. I have been opening the east-facing windows (smoke clouds are from w & s/w) to cool the house down.

    So does this count as an additional evidence of on-going collapse? Seems to me…

    The Brightside of Crimewaves

    https://www.counterpunch.org/2021/07/23/the-brightside-of-crimewaves/

    Tuning into the evening news has begun to take on all the charming qualities of a seventies Scorsese flick. Some nights I have to wipe the blood from the screen. From coast to coast, from sea to rising sea, the mean streets of America are being rocked by a crime wave the likes of which we’ve never seen. After a thirty year drop in violent crime, 2020 has seen the biggest single year jump in homicides since they began recording such grim statistics in the 1960’s, with a 25% rise in a single year. And 2021 has all the makings of a Charles Bronson sequel.

    Last month’s leaked IPCC report cherry picked grim scenarios, but it’s just the latest in a long line of leaks intended to shape perception of climate science.

    Nearly time to put on the mask and walk out into the heat and sticky smoky red sunlight and see just how hot it is. Best put on a shirt and flip-flops aren’t working because the ground is so dry that the normal plant growth has died and dried into spikes of piercing intensity as I found out recently when I forgot to switch to thick Vibram-sole hikers… A weed stem went through the sandals and put maybe a 3/4 inch deep puncture wound while walking with the brown dog one morning a week ago. Oops. Still tender but not infected. Won’t do that again.

Kevin Hester is currently living on Rakino Island, a small island in the Hauraki Gulf near Auckland, New Zealand, monitoring the unravelling of the biosphere and volunteering at the Rakino Island Nursery is currently developing a proposal to create a marine reserve near by. The Island has no grid tied electricity or reticulated water.  I catch my own water from the roof and generate my electricity from the ample solar radiation on the island.
