Welcome to the crisis


Credit: Dheerav2


Previously posted on July 6, 2020. Reposted due to the extreme weather conditions all over the world (including Sweden) this summer. 

Erika Bjerström is a Swedish reporter and former environmentalist activist. "Klimatkrisens Sverige" is her recently published book about the climate crisis. Or rather the climate crisis in Sweden. It´s interesting comparing it to Jonathan Jeppson´s "Åtta steg mot avgrunden", reviewed by me elsewhere, another book on the climate crisis published in 2020 by a Swedish journalist. Jeppson´s book sounds apocalyptic, while Bjerström describes the climate crisis as something creeping and gradual. Ironically, this actually makes her book *more* scary than Jeppson´s. Although I don´t doubt that climate change could lead to apocalyptic consequences, the apocalypse meme as such feels old and worn out. We are being sold one every other week, it seems. But what if climate change is instead a slow decline that sneaks up on us, becoming "the new normal", until it´s suddenly too late? (Btw, I don´t believe Jeppson and Bjerström necessarily disagrees on the facts. I´m refering more to the general atmosphere of their respective books.) 


Sweden is warming twice as fast as the global average, since the country is situated very far north. The average temperature has increased with 1.7 degrees centigrade compared to preindustrial times. The climate zones in Sweden are moving north with about eleven meters per day. In the future, the mountain ranges in northern Sweden will no longer have an Alpine climate. The tree line has moved steadily upwards, with 230 meters in 100 years. The pristine Alpine landscape will be turned into an enormous forest of conifers and birches. More rain will make mosquitos and flies super-abundant. One of Sweden´s foremost tourist attractions will be turned into "a shrubby mosquito hell". In Abisko national park, the local Arctic flora and fauna is heading for a mass extinction. The average temperatures in the park have increased with two degrees since 1913. Trees now grow at places where there have been none for 7,000 years! Meanwhile, Swedish glacials have lost one third of their total area since 1916. The growing season in the Arctic has increased with four weeks in a century, according to detailed studies made in Abisko. The plants become higher, the winters milder. When the permafrost thaws, quicksilver leaks out into the food chain. This can eventually lead to detrimental consequences for both reindeer and the Native Sami population. The entire reindeer herding business might disappear, for this and other climate-related reasons. 

Climate scientists predict that the annual average temperatures in Sweden will increase with 3 to 5 degrees until the end of the century. In northern Sweden, the increase might be 10 degrees! There will on average be more rainfall, although it´s possible that some areas will become drier instead. Heat waves will increase in numbers, more people will die of the heat and various diseases which thrive in warmer climactic conditions. Due to disturbances in the jet stream, both high-pressure and low-pressure areas might "get stuck" above Sweden for longer periods than usual, leading to extreme weather. Clean water will become more scarce as groundwater supplies are diminished, lakes turn dystrophic, or becomes poisoned by cyanobacteria (blue-green algae). Warmer water temperatures means more virus and bacteria. Swedish towns built around lakes and rivers are flooded already today, and this too will only get worse in the future. Of course, water purification and air conditioning will still be operational - but this requires enormous amounts of energy, and might led to higher energy prices. 

Another problem are "invasive species". The author does point out that such species are invasive only from a utilitarian human viewpoint. Nature doesn´t have a "viewpoint" at all, it´s simply out there. Ticks can already be found all over Sweden. More ominous are the "monster ticks" Hyalomma marginatum and Hyalomma rufipes, which can spread dangerous tropical diseases such as Crimean-Congo hemorrhagic fever. But Sweden is also invaded by regular tick species from Russia, which live by sucking blood from farm animals, often spreading disease in the process. Aphids are spreading in the new climate. The profitable Swedish forest industry could in the near future be attacked by the emerald ash borer and a moth known as black arches. They could also destroy city parks. Blueberries and lingonberries might disappear from Swedish forests, devastating another local industry. Other plant species will thrive: ferns, nettles or the Asian knotweed, which grows everywhere and slowly kills all other vegetation. 

Swedish agriculture was for a long time in denial about the consequences of global warming. It was rather seen as an excellent opportunity to introduce soy, quinoa and edible maize, three cash crops not grown in Sweden at present. Today, such dreams have been replaced by cold (or rather hot) realities. Climate change will lead to bad harvests. The production of dairy products, meat and beer will also be negatively impacted. Consumer prices will rise. Sweden has a self-sufficiency rate of only 45%, having an extremely globalized economy dependent on international supply chains (including food). A more ironic effect of climate change will be that the most privileged people in Sweden will be hit first by rising sea levels (in the so-called Third World, it´s usually the poorest that are impacted first). The luxury houses at Falsterbo in southern Sweden might be literally flooded at some point in the future, destroying property valued at a total of 70 billion kronor! 

While Bjerström´s book is about local conditions in Sweden, it´s obviously impossible to avoid the global big picture. At some point, the area around the Mediterranean Sea will become literally impossible to inhabit, due to average temperatures around 40 degrees centigrade. And even before that, agriculture will become almost impossible. Millions of people from southern Europe, North Africa and the Middle East will move northwards, where the climate - despite everything I just said above - will still be tolerable compared to Mediterranean standards. They will be followed by even larger migrations from the tropics, which will also become uninhabitable. What will happen to Swedish democracy and hospitality when tens of millions of refugees want to get inside, perhaps desperately? One of the scientists interviewed by the author suggests that 50 million people might live in Sweden without any problems! (Today, Sweden has a population of 9 million.) Clearly a pro-immigration fanatic, since 50 million people *obviously* isn´t sustainable given all other facts mentioned in the book (and here above in the blog post). As a good liberal, Bjerström never calls for closed borders, but it´s difficult to see how this can be avoided already at much lower levels than 50 million. The book ends with some comic relief: an interview with an official optimist named Svante Axelsson who believes that of course we can solve all problems, blah blah.

My main take away from "Klimatkrisens Sverige" is that Nature will always find a way, even in the Anthropocene. The real challenge is for modern civilization, or at the very least the human species, to survive the coming storms. As long as the changes are as gradual as described in this volume, it´s still within the realm of the possible to adapt to them. Which doesn´t mean it will be easy! It requires a degree of national solidarity and resolve not seen in this country for a very long time. The problem, of course, is that Sweden ultimately cannot isolate itself from the rest of the world, or the rest of the atmosphere. Indeed, our little country might become a *very* valuable piece of real estate when the tropics and sub-tropics are emptied of human inhabitants, most of them moving north. Another problem is of course that the collapse will come even faster if we really would stop using fossil fuels tomorrow morning, suggesting that it won´t be done. The very same fossil fuels that "fuel" climate change in the first place... 

Perhaps the differences between Erika Bjerström and Jonathan Jeppson aren´t that large, after all.

Planet Antarctica

 


When I watched BBC´s "Frozen Planet II", I assumed the stromatolites shown at the end of episode 4 were computer animated rather than real. However, it seems the film crew *did* dive in Lake Untersee, a lake in Antarctica with a permanent ice cover that may have persisted for 100,000 years. 

And under the ice they filmed the previously mentioned stromatolites, bizarre structures created by myriads of cyanobacteria (the organisms previously known as blue-green algae). Perhaps inevitably, scientists find these extremophiles very interesting...since they may suggest that life is possible at Mars or Europa! Go figure.

But sure, I also go quasi-religious when I watch stuff like this, although in my case BBC´s descent into this Hadean world (did you know there are literal *deserts* in Antarctica complete with sand dunes?) rather invoke feelings of the utterly ineffable grandeur of Shiva the Destroyer...

Bring back Boomer science

 

Credit: Ad Meskens

Brontosaurus have been rehabilitated. 

Now, let´s bring back Pluto into planetary orbit, prove that cyanobacteria are really plants, and stop calling birds freakin´ dinosaurs (cuz they aint). And why not resuscitate Fred Hoyle´s steady-state theory of the universe, when we´re already at it? *And* admit that Neandertals were really Homo sapiens! 

Can we make this happen, fam?

The real Otherkin





"Nationalnyckeln till Sveriges flora och fauna" is a work in progress, published by Sveriges Lantbruksuniversitet (SLU), i.e. the Swedish University of Agricultural Sciences. The original ambition was to describe all (!) species of living organisms found in Sweden in about 100 volumes, published over a period of 20 years. 16 years into the project, only 20 volumes have been published, and something tells me we will never see the happy ending of this particular project! Still, the books produced so far *are* interesting, at least if you´re some kind of super-nerd with a strong tendency to favor invertebrates, mosses or fish. I´m pretty sure volume CV is the only encyclopedic treatment of the Psocoptera *with full color photos* available on the market, to take just one example.

The latest installment in this potentially never-ending series arrived earlier today at my COVID-restricted pick up location somewhere in Sweden. Yes, it´s volume DN 110-167, titled "Blötdjur. Sidopalpssnäckor - taggsäckssnäckor. Mollusca: Cimidae - Asperspinidae". Yes, folks, it´s time to give the small subsection of the nerd community who specialize in molluscan cladistics their due! This volume covers Heterobranchia ("the different gilled-snails"), more specifically the infraclasses Lower Heterobranchia and Euthyneura, minus the superorders Pylopulmonata, Eupulmonata and Hygrophila, to be covered in another volume at some unspecified later date. In plain English, most "standard" snails and slugs (the ones you eat, the ones that eat your vegetables, etc) have been excluded from this work, which concentrates almost exclusively on marine species, many of them positively bizarre. 

The authors make a valiant attempt to sort out the cladistically correct relationships between the taxa described in the book, and an even more daring attempt to describe the often quite strange anatomy and behavior of these "sea slugs and sea snails". I´m not sure if they really succeed. What was that again about "secondary detorsion" and "internal symmetry", or whatever it was? And what on earth is a "protandric hermaphrodite"? Yes, it means that an organism is born a male and later in life switches biological sex and becomes female. It also seems that many of these Mollusca have the "wrong" body plans altogether, which I suppose keep evolutionary biologists and geneticists up all night, scratching their heads. (Creationists have a ready answer: God did it to confound the non-believers! Why he created the protandric hermaphrodites is, alas, less clear.) 

The most bizarre creature in the entire volume is Elysia viridis, a sea slug with the ability to photosynthesize sun light! The authors even refer to it as a "plantimal", a term I assume is derived from science fiction. Through a process known as kleptoplasty, Elysia incorporates chloroplasts from green algae it consumes into its own cells, thereby becoming "solar-powered" like a plant. Since chloroplasts could be considered cyanobacteria, the relationship is a kind of "symbiosis". Here we have a true Otherkin, it seems! 

Compared to this, the capture of cnidarian nematocysts (stinging cells) by the Nudibranchia is almost trivial...

The species presentations contain information on morphology, behavior and ecology (if known), and range. There is also some information on the scientific names. No English summaries seem to exist, but the keys are bilingual. Most species are illustrated by color pics of their soft bodies and/or shells. Vernacular Swedish names, many of them weird, seems to have been invented by the authors and approved by the mysterious committee regulating such things. Trust me, we don´t know what on earth "klubbnuding", "dubbelvårting" or "Y-tecknad snigelkott" is supposed to mean (well, maybe barely)! 

This will hardly be a best seller, but if heterobranchs is your main thing in life, investing in a copy might be a good idea. At least if you understand Swedish. 

And perhaps even if you don´t.

Lawyering the mistletoe




“Fridlysta växter” is a book in Swedish about plants and somewhat-allied organisms protected by law in Sweden. As usual, illustrator Bo Mossberg´s name is more prominent on the front cover than that of the actual author, one Hans Rydberg. The reason is Mossberg´s local fame in Sweden – I suppose we could call him “the Lars Jonsson of plant and mushroom illustrations”. The book, published in 1995, was a collaboration with the Swedish “Sierra Club”, the Naturskyddsföreningen (NF). It´s both a field guide of sorts and an extended pitch for the specific form of environmentalism represented by the NF. Since the work is in Swedish, it´s of limited use to outsiders, but could perhaps be an interesting collectors´ item if you like plant illustrations. A weird detail is that the list of protected plant species at Swedish Wikipedia is from 1996, suggesting that very few updates have been made since the time this little book was published!

Rydberg argues that the entire system of making specific plant species “protected by law” doesn´t really help much. The right of landowners to exploit their land always takes precedence, and the best way to save threatened plant species isn´t to protect them one by one, but rather to shield entire areas from outside exploitation. After all, plants are part of wider eco-systems while being less mobile than many animals. Also, most of the legal protection is local or regional rather than national. Only the orchid family is protected all over Sweden. Nor is there a correlation between a plant being rare and a plant being legally protected!

That being said, Rydberg is strongly into the myth of “biodiversity”, something Nature is not (despite the romantic conceptions of many Green activists). He admits that floral diversity is often the result of *human* activity, most notably certain old fashioned agricultural practices. Take away these, and Nature suddenly becomes more homogenous (butterflies follow the same patterns). But if so, eco-activists must admit that they are making a human-centered choice between two human-created landscapes, not choosing “natural biodiversity”.

Otherwise, I loved the book for all the weird facts (or factoids?) it contains. Thus, it turns out that a species of bacteria is protected by the Swedish nanny state. Well, almost: Nostoc zederstedtii (the scientific name of this Something) is a blue-green alga and visible to the naked eye, but research suggest that these algae are actually closer to the kingdom of the bacteria, where they form a sub-group all their own known as cyanobacteria. The species in question can´t be plucked (or whatever it is humans do with cyanobacteria) in Lake Vettasjärvi in Lapland. Skipper, you have been warned. The lichen Letharia vulpina is protected, which makes me wonder, since it was used in bygone times to poison wolves – another protected species and apparently a favorite of the Swedish conservationist movement. Could there be a connection, LOL? Many of the protected species grow at the small island of Rörö off the Swedish west coast, including a highly aberrant variety of raspberry, known in proper Latin as “Rubus idaeus f. anomalus”. Hybrids where one of the parent species is legally protected are sometimes also legally protected – and sometimes not. (I suppose we could call this the “one seed rule” or something to that effect.)

There is also an interview with a bureaucrat at the agency responsible for environmental protection. It, too, is fun reading. Thus, you can´t remove orchids – unless you mow the lawn (or, I suppose the golf course) when it (weirdly) suddenly becomes OK to simply move on over the damn things. “Remove” is to be interpreted very broadly in other contexts, though. Thus, you can´t take a legally protected species even if it has been removed by somebody else and then simply left for dead. You can pluck the flowers of a legally protected species at your own backyard, provided *you* planted them there from seeds bought at a respectable vendor, but you can´t remove them from areas outside your private property even if you suspect they are feral descendant of your own legally reared plants. In the county of Västmanland, landowners can remove and sell mistletoe from their trees, but in the rest of the country, they can only fell the trees and destroy the mistletoe, but not sell it…

If you are a Paleo-Pagan Druid living in Sweden, the pro tip would be to buy land in Västmanland...

LOL!

Wow, do you need to be a lawyer to sort these things out? Gotta love it! OK, I admit. I read books like “Fridlysta växter” mostly for the entertainment factor…

Bacteria for boys





“The Pictorial Encylopedia of Plants and Flowers” by F A Novak is an originally Czech work. It has been translated to several foreign languages, including Swedish. As a kid, I and my best friend sneaked into the local library in secret to leaf through it. We had gotten into our tiny little heads that plants and flowers were somehow “girlie” and hence uncool for boys. Ha ha ha.

Actually, this huge volume contains a lot of cool stuff for boys, too: bacteria, cyanobacteria, algae, fungi, lichens and ferns. Plants? Flowers? But sure, most of the cyclopaedia does contain photos of flowery plants, unfortunately mostly in black-and-white. The editor did use the few colour plates relatively wisely. They feature orchids, the golden crocus, the poinsettia and…the fly agaric mushroom. More original is the inclusion of a colour photo of a…pineapple.

Not sure how to rate this somewhat strange product, which contains more illustrations than text (and hence information). Could work as a leaf-through volume on your book shelf (or the waiting room of a dentist?), but otherwise I say its use is limited and popularity somehow mysterious…
