climate – Dan Q

Three(ish) Weeks In Spain

Ruth, JTA, the kids and I are all back in the UK¹ after a three week period during which some or all of us were consistently in Spain. The whole adventure was the kind of masterpiece of epic planning that only Ruth could have pulled off, and it worked spectacularly².

A fawn-coloured French Bulldog lies comfortably on a blanket on a sofa, with her tongue sticking out in a large sideways blep. — I wasn’t around for the first week of the trip, but continued working from home (with the dog, pictured) as per the usual.

San Sebastián

Through clever permutations of remote-working from overseas (mostly by Ruth) and overlapping/intersecting stretches of annual leave (mostly by JTA and I), we were able to avoid having to send the dog to the dogsitter for a block of more than a single week³, didn’t need to break the bank on our collective leave budgets, and managed to give the kids the longest possible block of continuous immersion in the language and culture of Spain.

In the first week (when I wasn’t there), the kids got to take a mixture of surfing classes and Spanish language lessons in San Sebastián, among other activities. The Bordeaux wildfires caused some travel chaos for the others getting there, but they made it work in the end.

Tarragona

Later, I flew out to meet up with them and we switched to the opposite coast of Spain, staying in a delightful little villa North of Tarragona. The summer heatwaves that are affecting the continent made the middle of the day especially oppressive, so we did as the locals do and sensibly sheltered indoors during the hottest part of the day… but the kids in particular were glad to be able to take a dip in the pool to cool off.

Under nearly-cloudless skies and surrounded by trees and olive and grape-laden slopes, a stone villa and its outbuildings sit prominently under the bright sun. — The villa was a lovely building in a fabulous spot, nestled among hillside olive groves and vineyards, but the lack of wired Internet access/WiFi plus the signal-blocking stone walls made it more “disconnected” than we’d anticipated⁴!

As has become my tradition when travelling and on family holidays – because I’m an earlier riser than most, but also because I wanted to make the most of the coolest part of the day – I got out early most days for a whole bunch of geocaching expeditions⁵. But once others were awake we found plenty of other opportunities to explore the area.

Wide/panoramic view from a pagoda-like tower, where a woman and two children lean over a railing to look at a network of bridge-linked islands in a lake below, dotted with palm and other trees. — Parc Samà‘s breezy towers and water features took some of the heat out of the day, when we visited its attractive botanic gardens.

Having come from, remarkably, a similar level of temperature and humidity in the UK, I was interested to see how much greener everything was here on the Mediterranean coast. The plants here, better-adapted to hot and dry summers than those that we plant on our little island, were clearly more-suited to these kinds of conditions. Is it perhaps time that Britain started ditching her lawns and other year-round thirsty vegetation… instead planting more tropical-adjacent plants to provide shade (and carbon capture!) as the climate continues to shift?

A freshwater turtle pokes its head out of blue-green water near a rocky shore, with small black fish visible swimming in the depths. — This little fella had the right idea about keeping cool.

I enjoyed that we were able to split out time between a diversity of activities. A week-long jaunt can be dominated by a single activity – a skiing holiday, for example – but by the time you’re spending most of a month exploring a country, you want to be able to mix things up a bit, right?

A Roman aquaduct spans a forested valley. — Per local legend (and in common with many similar spans around the world⁶, which usually share a myth about the devil aiding in its otherwise-impossible construction in exchange for the first soul to cross it and then being tricked when an animal is sent across first), the Ferreres Aquaduct is also known as Devil’s Bridge, which lead me to observe that of *all* the architecture I’ve seen with which Hell’s ruler is credited, this might be the best (nice work, Satan!).

Sometimes we kept it slow-paced and relaxing, like reading by the pool while the children invent splashing-based games or playing board games in the shade. Other times we explored history and culture, like our visit to the Ferreres Aqueduct, the Catedral de Tarragona, or the old Roman amphitheatre.

Two children wearing VR headsets and holding parasols, in the ruins of a restored Roman amphitheatre. — An augmented reality tour of the amphitheatre was both engaging and educational for the kids, bringing to life its long and complex history: did you know it *started* as an amphitheatre, but later was the ground of a church (commemorating Saint Fructuosus, who was executed there), *then* became a prison, and now… it’s an amphitheatre again: in addition to being a historical monument it’s used to stage concerts and things!

And other times still we even did the typical “British tourist in Spain” things, like a trip to the beach or an expedition out on a catamaran to swim in the sea while the sun set.

Dan, a white man, drips from a swim in the sea as he stands, holding a plastic cup of white wine, on the deck of a catamaran. — I expected the catamaran trip to be a bit tacky, but it was actually lush. (I may have availed myself of the open bar, a bit!)

Obviously the biggest reason for our trip was to catch sight of the total solar eclipse as it passed over the region, and our villa’s garden/vineyard was without a doubt a superlative spot for this. We’d initially been concerned that visibility of the low-in-the-sky/close to sunset eclipse might be obstructed by the hills and that, therefore, we’d need to find another spot from which to spectate, but an early-in-the-week experiment of watching the sunset (with an eye on the clock) reassured us that this wasn’t the case. So – as long as we were lucky with the cloud cover – we should be set.

Dan sits on a sun lounger on a driveway, alongside a covered brick barbeque building. He's alongside two children doing the same, and all are wearing disposable eclipse glasses. — A particular highlight of the entire trip was hanging out as a family in our private vineyard, watching the solar eclipse.

I’ve been fortunate enough to have had great visibility of a total solar eclipse once before, in 1999, but honestly: this one beat it. The perfect location, the reds of the setting sun, the “moon illusion” exaggerating the perceived size of the moon as it approached the sun, the joy of vicariously sharing in the childrens’ wonder… all of these made the whole experience pretty mind-blowing.

The sun completely occluded by the moon. — You’ve seen pictures of eclipses before, but this one is mine. I maintain that even the *good*/professional photographs are poor substitutes for the real experience, though!

We watched, we awed, and then we saw the still half-obscured sun gradually disappear over the horizon. And then, a round of hugs and cheers and conversation later, we sat up late to enjoy the Perseids begin their nocturnal display.

Over the silhouette of hills, a total solar eclipse is just coming to an end, with a 'diamond ring' effect resulting from the sun's reappearance visible. — Mostly I was looking at the sky (through the safety of my eclipse glasses, of course). But I managed to snap a handful of photographs that, despite the limitations of my phone’s camera, came out pretty well.

PortAventura

After our week in the villa we delivered JTA to the airport to return home. Then Ruth, the kids and I drove on to PortAventura, perhaps our favourite theme park anywhere in the world. Since our last visit, the younger kid has reached a milestone of height that permits him to ride all of the largest rides, and he was excited to take advantage of this newfound privilege.

A man (Dan), a woman (Ruth), and two children sit in a circular boat on a 'river rapids' style ride. — A particularly useful thing about PortAventura compared to some other theme parks is that it’s *designed with heatwaves in mind*: it’s got lots of natural shade, cooling-off areas, and the right ratio of water rides for when you positively, absolutely need a good soaking.

Both the elder child and I were particularly excited to share with him my favourite non-looping rollercoaster, Shambhala. Shambhala is simply excellent: it’s a highly-vertical smooth ride with a free and open-feeling restraint that, collectively, give amazing “air” and a sensation of “flying” that’s hard to compare to almost any other coaster ride I’ve been on. I could sing its praises aplenty.

A man with a screwdriver repairs the restraint system on a rollercoaster car. — The second we reached the front of the line for our first ride on *Dragon Khan*… it broke down. But we got to watch it being repaired right in front of us, so that’s cute!

Going to Disneyland Paris and PortAventura in the same summer gives me the confidence to say: PortAventura is the better theme park. The rides, the theming, the food, the queue management, the accommodation, the value-for-money… it’s all better. So if you’re considering a European theme park trip and you don’t care about getting your photo taken with Goofy or whatever… PortAventura would be my suggestion.

PortAventura’s water park is good too, although it was pretty busy on the day we went. Their 30-metre tall near-vertical waterslide King Khajuna is a little intimidating⁷, but nothing our thrillseeking little man wasn’t up for.

Barcelona

Finally, we made our way to Barcelona for a “wind-down” couple of days at a hotel we’ve always enjoyed there. Aside for being mistaken for staff while I was using my laptop by the rooftop pool, there’s little of note to say about it: we took it easy, did as little as we could get away with, and generally “unplugged” before our journey back to the UK and a return to normal life (boo!).

Altogether a fabulous trip… and a really interesting experiment in a model that we could replicate if we ever opted for a three week (but drop-in/drop-out/telework) holiday in future. Though… I’d again want (our scheduling queen) Ruth to wrangle the logistics, because it gets complicated when there are so many moving parts!

Footnotes

¹ Although not in our house, of course, which is still being repaired following the flood in February; it’s now F-Day plus 191 days… more on that in a future blog post, I’ve no doubt.

² For a while, she was talking about trying to engineer it into a five-week expedition spanning both this and our trip to France earlier in the summer (to which JTA, the kids and I drove/LeShuttle’d, and to which Ruth flew following a work-related event in Austria: my, what a cosmopolitan life we’re leading this year!). But that’d have been an enormously more-complicated affair and I’m glad we settled on this “simpler” trip in the end!

³ Not that she cares: the dog loves hanging out with her little doggy friends, and is always excited to be taken to our dogsitter‘s, where she also “commutes” for a workday or two most weeks.

⁴ During out post-holiday ‘retro’ (because of course that’s what we do), the lack of connectivity appeared as both a negative and a positive on some of our lists! Obviously we’re all aware that a little digital disconnection is healthy and valuable, but sometimes it takes being in the middle of nowhere to impose the requisite self-discipline to keep off your devices!

⁵ Geocaching logs: 1, 2, 3, 4, 5, 6, 7, 8, 9 (my 1000th successful find) – not that Geocaching.com can count that correctly! – 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37.

⁶ Obviously, the Devil’s Bridge nearest where I used to live and at which Ruth and I spent our first anniversary – back when we had no idea that we’d be able to make our relationship last… what…? 19 years this month!) – will always have a special place in my heart.

⁷ Reaching the top of King Khajuna’s tower, you can feel it swap in the breeze, and when you get to the slide itself its ‘horizon’ disappears precipitously until you shuffle completely up to it, at which point there’s little choice about your destination! While we queued for our first goes, we witnessed several people reach the top, change their minds, and turn back!

How the European heatwave fucked me up

CW: reference to bodily processes, broad discussion of illness

This year’s “once in a generation” weather

Last week was brutally hot across Europe, with multiple countries recording their hottest ever temperatures. Others including the UK repeatedly smashed their record for the month of June.

While climate change is a global problem, it affects different regions in different ways, and Europe is disproportionately affected by hotter temperatures and heatwaves.

The “Chicory House” we’re currently living in has terrible thermal characteristics, so we took the advice of wiser folks about staying cool. We created a “cold zone” in the living room with a portable air conditioner and for a few days I lived, worked, ate and slept mostly out of that one room (along with the children when they were trapped home because their schools had been shut down).

I thought our precautions would be sufficient, but I was wrong.

Heat exhaustion

After coming home from a shady morning dog walk on Friday², I felt hot and grumpy, tired, and incredibly thirsty. I pushed on through my workday’s Friday hotfix, then retreated to my bedroom for a nap.

This was a mistake: my bedroom is somehow the hottest room in the Chicory House.

On Saturday I felt dreadful. It was as if some tiny monster had discovered a switch: one that they could use, randomly and without warning, to toggle me from being a warm blooded animal to a cold blooded one and back again, intermittently wrecking my capacity to regulate my temperature.

Here: I made a simulator³ –

The Dan Thermoregulation Switch™️. Go on, you can flip it if you want. (Unless you’re in a feed reader or have JS disabled.)

I’d feel overwhelmingly hot but barely sweat, or I’d suddenly switch to feeling cold and shivering. A cool bath helped, but only for a little while: between going to bed on Saturday night and getting up on Sunday morning there were more hours during which I took a shower⁴ than hours during which I slept.

Water that I drank seemed to just fall straight through without touching either sweat glands or my bladder. Or else it’d come right back out the way it went in. Attempting to eat solid foods would result in hours of horrible abdominal cramps.

Clearly, I was quite unwell.

Opportunistic infection

If you’re looking at all of those symptoms and you’re thinking “wait, could this be heatstroke-related organ damage?”… then yeah, that was one of my concerns. I mean: I’ve only once felt more-ill than I did on Sunday… and that was over a decade ago when I was hospitalised with an antibiotic-resistant kidney infection.

I can’t claim that I wasn’t influenced by growing reports of long heatwave-related waits at A&E departments. If I have to sit somewhere uncomfortable, feeling rotten, then it might as well be at home!

An orange, sliced into quarters, alongside a glass of slightly-opaque water. — By Monday afternoon I’d graduated out of a fluids-only diet to one that allowed mostly-water food. Like oranges, served here with an oral rehydration therapy drink (blech).

But also: on the balance of probability, I figured I knew what had happened. I’d suffered a moderately severe heat exhaustion that’d weakened my immune response to some kind of opportunistic bacterial gastroenteritis⁵.

When it reached Monday, the monster had stopped flicking the thermoregulation switch (did you set it the way you think it belongs, by the way?), but my digestive system still just seemed to be in its degraded state. That is: just an inflamed and painful tube through which I could pour fluids.

I’ve produced what I feel is a more-accurate illustration of the operation of my digestive system right now.
With thanks to weareheroes for the icons, used under a Creative Commons license.

So I finally caved and saw a doctor, who prodded and poked me and said… yup, my hunch was right and I should go back to lying in the cool and living on fluids and come bother him again only if it doesn’t get any better (or gets worse).

If you’d noticed that I’d been unusually “offline” for the last few days⁶… well, it’s because mostly I’ve been lying in bed and/or groaning in discomfort.

But I feel like I’m moving in the right direction again now, and I’m optimistic that when I try solid food again today that maybe I’ll be able to digest it. Fingers crossed!

Lessons learned

So what have we learned from all of this:

Heat exhaustion is real, and it’s nasty, and it can leave you vulnerable to all kinds of other problems.
(Even when my guts are in pain) I can trust my gut feeling on whether or not it’s a medical emergency⁷. Please disregard any Aber Effect comic which implies otherwise.
You can probably be trusted with access the the Dan Thermoregulation Switch. You didn’t play with it at all!

Let me know below whether I was right to let you play with the switch. And look forward to hearing more from me now that I’m working towards feeling better again.

Footnotes

¹ Obviously this is a joke, but the world we live in nowadays means that I feel that I have to say so.

² It’s possible my heat exhaustion had begun to build up before Friday: Ruth observes that I reported feeling dizzy or lightheaded a couple of times during the week prior. But for the sake of the story, let’s call Friday the start of the problem.

³ If you can’t see the results of toggling the switch, it’s because I’m too far away from you to hear me groaning. Or maybe because it’s not that accurate a simulation. One of those.

⁴ Several times, literally lying foetal, exhausted, on the floor of the shower, only moving to tweak the dial to keep my body at the temperature I felt it “should” be at.

⁵ I’ve no idea how my relatively-isolated lifestyle exposed me to such an infection, but it’s quite possible that it was brought home by somebody, even me, whose immune system was working better and had it suppressed to the point of being asymptomatic… but with me exhausted and dehydrated it was able to gain a foothold. Or maybe it came from somewhere else. Perhaps I just need to stop French kissing the dog?

⁶ I was running a daily streak of 177 days of consecutive blogging – every day so far this year! – up until I got ill, so posting nothing to DanQ.me for four days… probably sounded like I was dead!

⁷ Sometimes it’s just bad sun tag-teaming with a bad stomach bug!

Hotdog Among the Trees

As the UK’s heatwave continues, the dog and I were delighted that this morning was sufficiently overcast that we could manage a proper walk without completely melting.

Her breed copes badly with the heat and we’ve lately had to keep her indoors or in the shade more than she’d like, so a chance to run around among the trees was very welcome!

[Bloganuary] Live Long and Prosper

This post is part of my attempt at Bloganuary 2024. Today’s prompt is:

What are your thoughts on the concept of living a very long life?

Today’s my 43rd birthday. Based on the current best statistics available for my age and country, I might expect to live about the same amount of time again: I’m literally about half-way through my anticipated life, today.¹

Naturally, that’s the kind of shocking revelation that can make a person wish for an extended lifespan. Especially if, y’know, you read Andrew’s book on the subject and figured that, excitingly, we’re on the cusp of some meaningful life extension technologies!

My very first thought when I read Andrew’s thoughts on lifespan extension was exactly the kind of knee-jerk panic response he tries to assuage with his free bonus chapter. He spends a while explaining how he’s not just talking about expending lifespan but healthspan, and so the need healthcare resources that are used to treat those in old-age wouldn’t increase dramatically as a result of lifespan increase, but that’s not the bit that worries me. My concern is that lifespan extension technologies will be unevenly distributed, and the (richer) societies that get them first are those same societies whose (richer) lifestyle has the greater negative impact on the Earth’s capacity to support human life.²

Andrew anticipates this concern and does some back-of-napkin maths to suggest that the increase in population doesn’t make too big an impact:

In this ‘worst’ case, the population in 2050 would be 11.3 billion—16% larger than had we not defeated ageing.

Is that a lot? I don’t think so—I’d happily work 16% harder to solve environmental problems if it meant no more suffering from old age.

This seems to me to be overly-optimistic:

The Earth doesn’t care whether or not you’re happy to work 16% harder to solve environmental problems if that extra effort isn’t possible (there’s necessarily an upper limit to how much change we can actually effect).
16% extra population = 16% extra “work” to save them implies a linear relationship between the two that simply doesn’t exist.
And that you’re willing to give 16% more doesn’t matter a jot if most of the richest people on the planet don’t share that ideal.

Fortunately, I’m reassured by the fact that – as Andrew points out – change is unlikely to happen fast. That means that the existing existential threat of climate change remains a bigger and more-significant issue than potential future overpopulation does!

In short: while I’m hoping I’ll live happily and healthily to say 120, I don’t think I’m ready for the rest of the world to all suddenly start doing so too! But I think there are bigger worries in the meantime. I don’t fancy my chances of living long enough to find out.

Gosh, that’s a gloomy note for a birthday, isn’t it? I’d better get up and go do something cheerier to mark the day!

Footnotes

¹ Assuming I don’t die of something before them, of course. Falling off a cliff isn’t a heritable condition, is it? ‘Cos there’s a family history of it, and I’ve always found myself affected by the influence of gravity, which I believe might be a precursor to falling off things.

² Fun fact: just last month I threw together a little JavaScript simulator to illustrate how even with no population growth (a “replacement rate” of one child per adult) a population grows while its life expectancy grows, which some people find unintuitive.

Alpha-Gal and the Gaia Hypothesis

Ticking Point

An increasing number of people are reportedly suffering from an allergy to the meat and other products of nonhuman mammals, reports Mosaic Science this week, and we’re increasingly confident that the cause is a sensitivity to alpha-gal (Galactose-alpha-1,3-galactose), a carbohydrate produced in the bodies of virtually all mammals except for us and our cousin apes, monkeys, and simians (and one of the reasons you can’t transplant tissue from pigs to humans, for example).

Lone star tick — The lone star tick (You call that a star, tick? Looks like a blob to me!), one of several vectors for alpha-gal sensitivity.

The interesting thing is that the most-common cause of alpha-gal sensitivity appears to be the bite of one of a small number of species of tick. The most-likely hypothesis seems to be that being bitten by such a tick after it’s bitten e.g. deer or cattle may introduce that species’ alpha-gal directly to your bloodstream. This exposure triggers an immune response through all future exposure, even if it’s is more minor, e.g. consuming milk products or even skin contact with an animal.

That’s nuts, isn’t it? The Mosaic Science article describes the reaction of Tami McGraw, whose symptoms began in 2010:

[She] asked her doctor to order a little-known blood test that would show if her immune system was reacting to a component of mammal meat. The test result was so strongly positive, her doctor called her at home to tell her to step away from the stove.

That should have been the end of her problems. Instead it launched her on an odyssey of discovering just how much mammal material is present in everyday life. One time, she took capsules of liquid painkiller and woke up in the middle of the night, itching and covered in hives provoked by the drug’s gelatine covering.

When she bought an unfamiliar lip balm, the lanolin in it made her mouth peel and blister. She planned to spend an afternoon gardening, spreading fertiliser and planting flowers, but passed out on the grass and had to be revived with an EpiPen. She had reacted to manure and bone meal that were enrichments in bagged compost she had bought.

Of course, this isn’t the only nor even the most-unusual (or most-severe) animal-induced allergy-to-a-different-animal we’re aware of. The hilariously-named but terribly-dangerous Pork-Cat syndrome is caused, though we’re not sure how, by exposure to cats and results in a severe allergy to pork. But what makes alpha-gal sensitivity really interesting is that it’s increasing in frequency at quite a dramatic rate. The culprit? Climate change. Probably.

It’s impossible to talk to physicians encountering alpha-gal cases without hearing that something has changed to make the tick that transmits it more common – even though they don’t know what that something might be.

…

“Climate change is likely playing a role in the northward expansion,” Ostfeld adds, but acknowledges that we don’t know what else could also be contributing.

Meat Me Half-Way

To take a minor diversion: another article I saw this week was the BBC‘s one on the climate footprint of the food you eat.

BBC graph showing climate impact of common foods. Beef is terrible *unshocker*. — An average serving of beef contributes almost 8kg of greenhouse gases, compared to around 1kg for chicken. Thanks, Beeb (click through for full article).

A little dated, perhaps: I’m sure that nobody needs to be told nowadays that one of the biggest things a Westerner can do to reduce their personal carbon footprint (after from breeding less or not at all, which I maintain is the biggest, or avoiding air travel, which Statto argues for) is to reduce or refrain from consumption of meat (especially pork and beef) and dairy products.

Indeed, environmental impact was the biggest factor in my vegetarianism (now weekday-vegetarianism) for the last eight years, and it’s an outlook that I’ve seen continue to grow in others over the same period.

Seeing these two stories side-by-side in my RSS reader put the Gaia hypothesis in my mind.

SMBC comic frame: "Yeah, I don't buy it. If Earth is self-regulating and alive, why hasn't it produced an immune response against humanity?" — If you want a pop-culture-grade introduction to the Gaia hypothesis in the context of climate change, this SMBC comic does the job, and does so almost with fewer words than this caption explaining that it does so.

If you’re not familiar with the Gaia hypothesis, the basic idea is this: by some mechanism, the Earth and all of the life on it act in synergy to maintain homeostasis. Organisms not only co-evolve with one another but also with the planet itself, affecting their environment in a way that in turn affects their future evolution in a perpetual symbiotic relationship of life and its habitat.

Its advocates point to negative feedback loops in nature such as plankton blooms affecting the weather in ways that inhibit plankton blooms and to simplistic theoretical models like the Daisyworld Simulation (cute video). A minority of its proponents go a step further and describe the Earth’s changes teleologically, implying a conscious Earth with an intention to protect its ecosystems (yes, these hypotheses were born out of the late 1960s, why do you ask?). Regardless, the essence is the same: life’s effect on its environment affects the environment’s hospitality to life, and vice-versa.

There’s an attractive symmetry to it, isn’t there, in light of the growth in alpha-gal allergies? Like:

Yesterday – agriculture, particularly intensive farming of mammals, causes climate change.
Today – climate change causes ticks to spread more-widely and bite more humans.
Tomorrow – tick bites cause humans to consume less products farmed from mammals?

Daisyworld in SimEarth — Both my appreciation and my rejection of Gaia Hypothesis can probably be traced to me playing way too much *SimEarth* as a teenager. Here’s my Daisyworld in state of equilibrium, because I haven’t yet gotten bored and spawned dinosaurs to eat all of the daisies.

That’s not to say that I buy it, mind. The Gaia hypothesis has a number of problems, and – almost as bad – it encourages a complacent “it’ll all be okay, the Earth will fix itself” mindset to climate change (which, even if it’s true, doesn’t bode well for the humans residing on it).

But it was a fun parallel to land in my news reader this morning, so I thought I’d share it with you. And, by proxy, make you just a little bit warier of ticks than you might have been already. /shudders/

If Doggerland Had Not Drowned

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

by Lee Rimmer

…

As well additional land around our familiar coastlines, the lower sea level reveals a low lying 9,000 square mile landmass called Doggerland – named after Dogger Bank, the large sandbank which currently sits in a shallow area of the North Sea off the east coast of England (dogger being an old Dutch word for fishing boat).

Doggerland had a rich landscape of hills, rivers and lakes and a coastline comprising lagoons, marshes and beaches. It had woodlands of oak, elm, birch, willow, alder, hazel and pine. It was home to horses, aurochs, deer, elks and wild pigs. Waterfowl, otters and beavers abounded in wetland areas and the seas, lakes and rivers teemed with fish. It was probably the richest hunting and fishing ground in Europe at the time and had an important influence on the course of prehistory in northwestern Europe as maritime and river-based societies adapted to this environment.

…

Lee Rimmer (Abroad in the Yard)

I love a bit of alternative history fiction, and this is a big one, going all the way back to prehistoric times. What if the period of global warming that took place thousands of years ago, “sinking” Doggerland and separating the formerly-connected British Isles from one another and from the European mainland? The potential impact is massive, affecting geography, history, and politics indefinitely, and it’s fun to think – and read – about.

The Dirty Secret of the Global Plan to Avert Climate Disaster

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

In 2014 Henrik Karlsson, a Swedish entrepreneur whose startup was failing, was lying in bed with a bankruptcy notice when the BBC called. The reporter had a scoop: On the eve of releasing a major report, the United Nation’s climate change panel appeared to be touting an untried technology as key to keeping planetary temperatures at safe levels. The technology went by the inelegant acronym BECCS, and Karlsson was apparently the only BECCS expert the reporter could find.

Karlsson was amazed. The bankruptcy notice was for his BECCS startup, which he’d founded seven years earlier after an idea came to him while watching a late-night television show in Gothenburg, Sweden. The show explored the benefits of capturing carbon dioxide before it was emitted from power plants. It’s the technology behind the much-touted notion of “clean coal,” a way to reduce greenhouse gas emissions and slow down climate change.

Karlsson, then a 27-year-old studying to be an operatic tenor, was no climate scientist or engineer. Still, the TV show got him thinking: During photosynthesis plants naturally suck carbon dioxide from the air, storing it in their leaves, branches, seeds, roots, and trunks. So what if you grew crops and then burned those crops for electricity, being sure to capture all of the carbon dioxide emitted? You’d then store all that dangerous CO₂ underground. Such a power plant wouldn’t just be emitting less greenhouse gas into the atmosphere, it would effectively be sucking CO₂ from the air. Karlsson was enraptured with the idea. He was going to help avert a global disaster.

Abby Rabinowitz and Amanda Simson (Wired)

Wonderful but horrifying longread about the truth of the theoretical effectiveness of the Paris Agreement. The short: if we’re going to keep global temperature rises under a “bad” 2°C rather than closer to a “catastrophic” 4°C, we need to take action, but the vast majority of the plans that have been authored on how to do that rely on investment in technologies and infrastructure that nobody is investing in and that might not work even if we did. We’re fucked, in short. See also this great video about greening the Sahara in an effort to lock carbon into plants (another great idea that, surprise surprise, nobody’s investing in).
