Scientists Amazed as Canadian Permafrost Thaws 70 Years Early:

Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared.

[...] With governments meeting in Bonn this week to try to ratchet up ambitions in United Nations climate negotiations, the... findings, published on June 10 in Geophysical Research Letters, offered a further sign of a growing climate emergency.

The paper was based on data Romanovsky and his colleagues had been analyzing since their last expedition to the area in 2016. The team used a modified propeller plane to visit exceptionally remote sites, including an abandoned Cold War-era radar base more than 300 km from the nearest human settlement.

Diving through a lucky break in the clouds, Romanovsky and his colleagues said they were confronted with a landscape that was unrecognizable from the pristine Arctic terrain they had encountered during initial visits a decade or so earlier.

The vista had dissolved into an undulating sea of hummocks - waist-high depressions and ponds known as thermokarst. Vegetation, once sparse, had begun to flourish in the shelter provided from the constant wind.

[...] Scientists are concerned about the stability of permafrost because of the risk that rapid thawing could release vast quantities of heat-trapping gases, unleashing a feedback loop that would in turn fuel even faster temperature rises.

No word on whether or not the Wicked Witch of the West had anything to do with it.

    Fortune is a matter of perspective. From the perspective of the rich old men who have been driving climate science in a particular direction for decades, this was both the desired and fortunate outcome.

    For anyone under the age of 30 who hasn't inherited $100M+ from previous generations, this could be very unfortunate indeed.

        Old men who made their fortunes in industries which produced mass quantities of greenhouse gasses have been pushing the science to deny, delay, and otherwise push back the perceived impacts of said greenhouse gasses for as long as possible, so that they may continue to grow their fortunes without having to change their business models which have worked so fortunately for them.

        Any scientist who might have come out in 1990 and predicted that by 2020 the permafrost would be thawed would have been laughed out of his career for the ensuing three decades - mountains of denial science have that kind of effect on otherwise unbiased researchers and theorists. Some of the denial science is obviously biased by its backers, but not all of it, and it skews the community, in the fortunate direction for the backers.

        Of course, those of us who gave fortune to these titans of industry reaped some short term benefits in the exchange, but in the future we and our descendants will be paying the true costs of our past purchases of coal fired electricity, oil fired transportation, high energy building materials (steel, concrete), etc. On balance, I'd say if you didn't inherit $100M+ from the previous generation, in 50 years you and your descendants are going to be net-screwed by the decisions to press onward with mass greenhouse gas emissions.

        Of course, we allow ourselves to be led by the $100M+ trust fund babies and their self serving goals, so I suppose we asked for this at the ballot box.

            Not "laughed off stage", but many predictions were eliminated as "alarmist" or "politically unacceptable...try to say something they'll be willing to hear". And, to be fair, the observable evidence even a decade ago wasn't really convincing...there were multiple ways to interpret it (and they were ALL used...including "it's nothing to worry about"). Face it, prediction is an inexact science, so a model should never be completely convincing.

            OTOH, the reason the more extreme predictions weren't factored into the IPCC report was that they were unacceptable, not that the models were unreasonable.

              Observable evidence for what? That the temperature record shows an increase since 1900? I don't think anyone ever doubted that. Instead they wondered about the reasons for this change (bad data, some natural cycle, etc).

                Given the way they keep altering historical data to fit their current theories, and then deleting the original data I do doubt exactly that.
                Note I said doubt, not disbelieve. They have screwed with the data enough that I no longer trust them.

          Also, here you go:

          Global “greenhouse” warming forecasts indicate that the high latitudes of the earth may warm by about 3–12° C by the middle of the next century as the result of an effective doubling of the greenhouse gas content of the atmosphere.
          [...]
          Continued climatic warming would eventually cause much of the discontinuous permafrost in Alaska to thaw since it is generally already within 1°- 2° C of the melting point.
          [...]
          As can be seen from this table, a rise in the mean annual temperature of about 6° C is indicated over roughly the next 60 years, for a projected rate of rise of 1° C per 10 yr. With much of Alaska's permafrost presently no colder than - 1 - -2 °C, the threat to permafrost-based foundations is obvious.

          https://ascelibrary.org/doi/10.1061/%28ASCE%290887-381X%281990%294%3A1%286%29 [ascelibrary.org]

          So there you go, it was predicted the temperature would rise ~1 °C per decade back in 1990 and needed to rise 2 °C to start thawing the permafrost. So by 2020 they would predict a temperature rise of 3 °C and a thawing permafrost.

              http://www.populartechnology.net/2013/02/the-1970s-global-cooling-alarmism.html [populartechnology.net]

              It really was one of the big climate worries in the seventies and very early eighties. There were several trends that indicated the planet was cooling, and the fear was that more snow meant more reflected sunlight, more cooling means more snow. Cool the atmosphere enough and all the water falls out of it, greatly reducing the greenhouse effect and locking in the 'Snowball Earth'. There were semi-serious proposals to spray graphite on expanding snowfields.

              Those citations in the above link are mostly media stories, but not all. Current warmists claiming that there was never an ice age scare is just another way they damage their credibility with those who can remember just that.

    You ask me a numeric question. I tell you my prediction is that it's 50, with a viable range of 40 to 60. Whether the actual answer is 90, or 10 would mean exactly the same thing - whatever I'm using to predict things is worthless.

    Things happening radically ahead of pace doesn't mean "See, everything we predicted would happen - but even faster!" It simply means that people making predictions are likely using completely broken models. These models have, time and again, proven themselves to be extremely inaccurate even on relatively short time frames such as the 10-30 year range which we now have numerous prediction:test pairs to contrast against. This, of course, does not mean that we should go balls out and start building coal plants every 50km, but it does mean that what these models say about what Earth might look like 50, or 100 years in the future is almost entirely irrelevant.

    We've had 40 years of alarmism now, and it seems to have done nothing but split society into two groups. One group that's having borderline anxiety disorders with a neverending series of apocalyptic predictions, and another group that's grown even more distant from the issue in no small part because of constant reminders, such as this, that climatologists are starting to act more and more like astrologers. That's also not a random slight - astrology was treated as a science as serious and scholarly as any other for hundreds of years. Even thought we can now see it was based on less than nothing (e.g. - one important aspect of astrology is planets suddenly stopping and starting to go the other way - an optical illusion driven by the assumption that everything in the universe rotated around the Earth), the ability for weak correlations to affirm biases was enough for many very intelligent individuals to take it very seriously for many centuries.

    The only thing that gives climatology an austere of meaningfulness is that 'they may not be getting it exactly right, but climate science is hard and they are definitely getting the general trend correct.' But this general trend is meaningless. The Earth is obviously warming and has been warming since even before the industrial revolution. This argument of a 'general trend' meaning something is like me claiming to have a system that can predict where the stock market will be in 100 years, and because I said it'd be really high - you defend my model because, even though it gets everything completely wrong, it says the stock market will go up and, lo and behold, the market is going up!
