So-are all our bodies full of microplastics, ready to reach out their oily hands and strike us all down with heart disease, tumours and goodness knows what else, or not? It’s a story we’ve covered before (LSS 9 4 24) and to be fair we even approached it with a certain moderation (LSS 12 3 25)
But who are we to advise you, when we can point you at once to the works of science journalist Debra Mackenzie, writing in the Guardian? [1] Not only is the science interesting. She also gets to the heart of why scientific controversies arise. In the case of microplastics, because one lot of researchers (medical folk) are approaching the problem one way. And another lot (analytical chemists) come from somewhere different, with other methodologies And this is ominous: as we have seen time and again, with CFCs, with tobacco and with fossil fuels, there could be interested parties who will be waiting to pounce on those disputes , to use them to allege that the science is not certain, that no action is needed. To quote one of the more chilling passages of Debra’s article
The plastics industry is more powerful than the CFC-makers were, and it has friends who know how to manufacture doubt. (Researchers I spoke to said that their papers have been denounced to journal editors by chemical industry figures who were not analytical experts.)
Now we at LSS are not medical experts. gentle readers. We do not know where the truth lies, although we may suspect. And, as in many scientific debates, there may be actors with differing levels of enthusiasm about where the evidence ultimately points. In any case, you should read Mackenzie’s article. You will learn a great deal more than just about plastics..
Two stories today give us serious pause for thought. Both concern our old bête noire of climate change. It’s not the bad news per se: we’re kind of inured by now. It’s the way they open the door to thoughts with actual evolutionary consequences: but more of that later.
The first story, from Ajit Niranjam of the Guardian, is a grim reprise of current trends. [1] 2025 is the third hottest year on record. For us their killer fact is context: El Niño, which had boosted heating trends in 2023 and 2024, was waning by 2025, so even that fig leaf has been stripped away. And talking of stripping away, what about the forests, which might have soaked up a little more of all that lethal CO2 affording us a few more years of life? Well as this truly impressive piece of visual journalism by Ashley Kirk and Pablo Gutiérrez shows, they are being devasted by the very wildfires which global warming has brought about. This is what information theorists call a self re-inforcing feedback loop which would be intellectually interesting to study if anyone is left alive to do so.
And the evolutionary reason we are so worried? Our species carries ancient cognitive machinery that buckles under modern complexity. Human cognition defaults to fast, intuitive, pattern‑matching heuristics — brilliant for spotting predators in the savannah, disastrous for interpreting climate models This “cognitive autopilot” leaps to conclusions, prefers simple stories, and treats feelings as evidence. A species that cannot update beliefs in the face of overwhelming evidence, that treats data as optional, that cannot overcome its own cognitive biases is evolutionarily brittle. It will eventually be outcompeted by one that can. Can anyone think of a name for it?

It’s a question a lot of people are asking as the world is increasingly lashed by the storms, floods and wild fires unleashed by global warming. And when you realise that the world’s fossil‑fuel giants collectively command over six trillion dollars a year — more economic power than most nations on Earth-it’s a tempting pot of money to aim at. What would you do with even one of those trillions? So we asked our Legal People: Can an individual sue a fossil fuel company to pay for flood/fire/storm damage, or the rising insurance premiums, that go with all those things?
The chances of getting anywhere on your own are slim. Firstly, you must show that any damage has been made worse by global warming (there will always be a background level of storms and things). Secondly, that a specific company’s emissions and /or “misinformation” caused that extra damage. And above all that the company chosen has a “duty of care” anyway. Quite a big ask when you think how much legal brainpower that $6 trillion is going to buy against you.
However, joining in with group actions increases your chances of getting something back. [1] . In the USA there are now 86 lawsuits against fossil fuel companies, including the very biggest. This class alleges that these companies “knew about the dangers of global warming and did nothing”. Even worse, it is alleged, they “actively misled” about those dangers. These suits will be fiercely contested; and the Jury will decide, as they say.[2] But there is a juicy second front opening. Home owners in Washington State are suing oil companies for climate‑driven increases in insurance costs. which they allege “are driven by global warming.”[3] As such costs may well be set to rise astronomically for all of us, their battle is indeed a noble one.
In the meantime there at least two things you can do. Work with climate litigation NGOs Groups like ClientEarth, Global Legal Action Network,[4] and the Climate Litigation Network are actively exploring new legal strategies. Document your damages If future cases open the door to compensation, having detailed records of storm impacts and repair costs will matter. Courts are increasingly willing to treat climate damage as a foreseeable, preventable harm caused in part by corporate deception. That shift is what makes future individual claims more plausible. There’s little doubt at fossil fuel companies represent a big barrel of money. Could some of it one day belong to you?
We think we owe you a truly massive overwhelming apology, gentle reader. And this is why.
“Will the world end with a bang or a whimper?” is a question we’ve covered before here. We’ve even mentioned a few possibilities such as magnetic flips ,exploding volcanoes and more insidious effects like pollution and pandemics. (LSS passim)Yet it was while researching another topic entirely that we came across a wholly unexpected and entirely man-made problem that we thought you should know about: Nitrogen, [1] [2]and its derivative compounds which has been unleashed on an unprepared world in uncontrolled quantities for over a century. The reason it’s rising so fast is simple: we are manufacturing and releasing unprecedented quantities of reactive nitrogen—fertilisers, manure emissions, industrial by‑products—far beyond anything the planet’s natural nitrogen cycle ever evolved to handle.
Why so much? Because the Haber–Bosch process unlocked a torrent of synthetic nitrogen, and agriculture embraced it as a miracle. Global production of reactive nitrogen has soared to many times its pre‑industrial level. Locally, this can boost yields, but it comes with a hidden price: soils become chemically dependent, losing the microbial communities that once fixed nitrogen naturally. Excess nitrogen washes into rivers, fuelling algal blooms and dead zones; it volatilises into nitrous oxide, damaging the ozone layer; it accumulates in ecosystems, favouring a few aggressive species while starving others. And things are never so bad that they don’t get worse. Nitrous oxide is the quiet heavyweight of greenhouse gases. molecule for molecule, it traps far more heat than carbon dioxide and lingers in the atmosphere for over a century. It’s also the single largest ozone‑depleting emission humanity still produces. And yet most people barely register it. So what looks like abundance at the farm gate is, at planetary scale, a metabolic overload.
And this is the deeper tragedy: millions of farmers, each trying to solve a local problem—how to feed crops, how to secure a harvest—collectively drive a global destabilisation of the nitrogen cycle. We’ve built a civilisation addicted to excess nitrogen, and the system now expects those inputs just to function. The long‑term risk is that we push soils, waterways, and atmospheric chemistry past thresholds that cannot easily be reversed. What began as a triumph of human ingenuity has become a planetary dependence, and the bill for that dependence is only just beginning to arrive. A silent catastrophe of soil degradation, desertification, wetland collapse (LSS 28 5 24),biodiversity loss from nutrient overload, and fisheries collapse.
And now for our apology, gentle readers. For several years now we have been repeatedly warning you of the dangers posed by antibiotic resistant bacteria and climate change. We had not a single idea about this nitrogen crisis building up all around us. None whatsoever, We profoundly and unreservedly apologise to all of you-readers, contributors researchers and hard working staff, even the ones in HR. And we say this-never will such an oversight happen again in this mighty organisation. But do not be alarmed. From now on we will search the world ceaselessly to bring you news of fresh perils, unexpected lethal dangers which may be lurking ready to wipe us all out Or if not that, at least reduce the handful of survivors to subsistence-level barbarism in a lawless, violent post-apocalyptic world. We think we may even have uncovered a few already. Follow us if you want to know more about what they are.
There’s a simple view of history as series of pageants. Kings fight glorious battles, heroes like Nelson and Genghis Khan kill lots of people, talented artists like Michaelangelo gaily paint frescoes of the male nude all over the walls of some slightly dodgy cleric’s new palace It’s interesting, it’s fun, it excites podgy old men who have never been in a war to dress up in funny costumes. There’s only one problem with it, in fact,
It’s bollocks.
Starting slowly at first, reading the works of much clever people like Professor Kennedy[2] [3] we realised that History is driven by deep slow moving inexorable forces: things like climate, infant survival rates and technology. Britain rose because it was the first to develop modern commercial and industrial processes. It fell when other countries started to do those things better. Rome succeeded, for a while ,because it turned the Mediterranean Sea into a single trading zone in an epoch when sail was the most economic means of transport. It fell when plagues and climate change so decimated its population that it could no longer defend the frontiers of that zone. Above all it’s demographics, economics and logistics that determine the fate of nations, not battlefield heroics.
It is in this light that we present this article by George Monbiot of the Guardian. [1] For it attempts to address this single determining factor, both in our lives-and those of the next four or five generations to come. It doesn’t matter if you love immigration, or hate it. Whether you thought everything would solved by a rising population or a falling one, (as we used to). See this more as advice from a wise accountant to a failing family firm “this much is in your coffers, therefore these will be your spending options” In world terms, the arc is very simple. The population will grow a little while longer. Then it will start to fall. Precipitously. All decisions on defence, finance culture, even our own little idées fixées like antibiotics and climate change, shall be made in the light of this simple, ineluctable fact.
We have followed Monbiot on many topics for years; his writings are always stark and cogent. We urge to you look him up and read more. But today, for now, we beg you to read this one, It should lend perspective like nothing else.
The facts-objective, verified and indisputable- are chilling. The last three years of this decade have been the hottest on record. Vast areas are now being ravaged by wildfires or drowning in immeasurable floods. The latest gloomy news comes from Nature Briefing: a group of people who are as calm, objective and well-informed as any we have come across. :early Temperatures Reach Dangerous Highs, they report:
This year looks likely to tie with 2023 as the second-hottest ever on record. Last year was the hottest. “The three-year average for 2023-2025 is on track to exceed 1.5 ℃ for the first time,” says Samantha Burgess of the European Union’s Copernicus Climate Change Service, referring to the Paris Agreement pledge to limit global warming to 1.5 °C above pre-industrial levels. “These milestones are not abstract — they reflect the accelerating pace of climate change and the only way to mitigate future rising temperatures is to rapidly reduce greenhouse gas emissions.”Euronews | 2 min read
As we were once more digesting these gloomy words in the LSS Boardroom, Selina the tea lady came in with this morning’s refreshments. “Good heavens!” she observed. Well, that was the gist of what she observed. “Are you lot really going to put out another gloomy blog on Climate Change? Give them some hope, for once, why don’t you” Again we paraphrase: suffice to say we understand where her grandchildren derived the terms they used when we tried to stop them from vandalising the cars in the office car park. But she is right: why don’t we tell you that there is something you can do? Take agency and all that. It shall be by supporting or donating to the organisations which we have listed below. We have chosen all of them for their integrity, hard work and track records. But above all for their moderate, pragmatic approach to this problem. We are deeply suspicious of more extreme outfits who in our view only help Big Oil by alienating ordinary people. Here, then is that list. All need money. It is nearly Christmas. We leave you to join the dots between those last statements.
Was the Cambrian period (538-486 million years ago) the most significant in the history of Life? [1] Was there really a kind of biological explosion where simple single celled creatures suddenly transformed them selves into complex multicellular beasts with nervous systems, eyes, guts and feeding strategies? It’s always been a bone of contention with some shouting emphatically “yes” and others being a little more sceptical. “Sampling bias”, they say: correctly adducing that there were plenty of multicellular creatures in the Pre-Cambrian, it’s just very difficult to find their remains.
Now the proponents of the Big Change Theory have found their case strenghtened. Recent research. described here by Kate Ravilious for the Guardian, suggests a natural mechanism which drove the changes and caused a sudden leap in the diversity of life. According to Kate
changes in solar energy caused climatic changes that altered the amount of weathering of land surfaces – especially at high latitudes – with periods of fast weathering releasing bursts of nutrients into the oceans, which drove photosynthesis and pushed up oxygen levels, fuelling the high speed evolutionary changes. [3]
And the interaction of these changes in solar output with variations in the earth’s orbit would explain the timing and nature of these sudden leaps for life.
And our take? Something happened around Cambrian times, gentle readers-there really is a step change, as shown by the appearance of shells, backbones and all the other markers of our modern phyla. And the idea of a coinciding, plausible mechanism is persuasive indeed. However as veterans of the paleontological wars we have a few questions. Did the Cambrian explosion a generate an increase in total biomass, or just complexity of forms? If this pattern of solar cycles and variable orbit repeats every two or three million years, why have we not seen at least one comparable event since (500 million years is a long time) Were there no volcanoes, tectonic plates or asteroids to muddy the waters in the Cambrian, the way they did in the Permian or Cretaceous, for examples? We love the Cambrian explosion and the way it has driven curiosity and much good research. But like every Big General Idea-in science , history, psychology, whatever- we see them more as pointing the way to more research, not a final answer.
We never thought we’d see it. But Malaria is making a comeback in the British Isles [1] According to the latest findings from the UK Health Security Agency(UKHSA) cases rose by a whopping 32% from 2022 to 2023 making them the highest in 20 years. More than 2000 cases in fact. Now some of this is due no doubt to travel bounce backs after the COVID 19 pandemic. But once put into a broader context. the real pattern becomes both clear and alarming. Global warming is driving a massive spread of insect vector diseases. Dangerous diseases that almost seemed under control until the oil companies unleashed climate change on an innocent world
Staying with Britain just for now, William Hunter of the Mail [2] reports on the appearance of two deadly mosquitoes in the UK: the Egyptian mosquito Aedes aegypti and the appropriately named Tiger mosquito Aedes albopictus. For now these are isolated events, and under current conditions their spread may even be containable. But every year the climate gets a little warmer. Every year brings a higher chance that these vectors will spread their deadly triple load: Dengue Fever, Chikungunya and Zika. With all the consequences which wel- seasoned readers of this blog will recall from our earlier outings on this theme (see LSS 25 3 25, 25 10 21 and many others)
We confess to becoming a little angry when we we write stories like this: such disasters could have been so avoidable. Once, not so long ago these diseases were unknown in this islands except as travellers’ tales, or as the province of medical specialists. Now a wave is crossing the world. We know what the remedy is. If by any chance you are a parent reading these lines: this story is one more line of evidence among many. Your children can never be truly safe until global warming is finally controlled and reversed.
Kingston on Thames, Surrey, England. Spring 1962. A brand new Ford Zodiac pushes out from a brand-new house on a brand-new estate to begin a Sunday outing down to the south coast. Mum, Dad and their two kids on the back seat pass rows of new houses, all like theirs, all lived in by people like them. With cars like theirs at the fronts. This is Macmillan’s England, and people have never had it so good. Even, for the first time, the working classes. As the last new estates around Chessington drop behind and the real country begins at Box Hill, someone puts on the car radio. Listen! It’s the Shadows Wonderful Land,: and here, today, its dreamy tones are true. For as they head south on the A24 (soon to be massively widened) the temples of all this wonderful modernity are still visible in the brave new petrol stations and car showrooms sprouting across the sleepy countryside. The car has made people profoundly mobile and independent. People talk about them endlessly. Buy them, sell them Discuss performance. Your car is a badge of who you are, where you have arrived at, especially if you are a man. As our travellers pull into Worthing for a welcome ice cream they have indeed crossed a wonderful land.
This is the brave new world still remembered as the base line by the two children in the back of the Zodiac. Fast forward 2025 and they are well into their seventh decade. But they still remember the promise of those years with aching nostalgia. Their own lives, minus the usual vicissitudes of marital, family and work problems, have been tolerable enough: prosperous even, as their waistlines testify. But outside the narrow world of work and golf club, there have been disturbing changes. First crack in the wall came with the 1973 oil crisis, which demonstrated their country’s humiliating dependence on foreign oil. Tax cuts and North Sea Oil brought a brief sugar rush of prosperity: but now the world is a dark distrustful place hopelessly split between rich and poor where nothing ever works and everything is broken, from roads to trains to hospitals. Foreigners just keep coming and coming and coming. Above all the USA, their great patron and guarantor of all their security, is rapidly losing its ability to prosper and protect.
Now add something worse. All those grandchildren they sent off to University have come home to tell them that everything they believed in was wrong. That burning oil warms the planet to disastrous levels. [1] That vehicle emissions are a massive cause of mental and physical health disorders.[2] So are the plastics made from oils in abundance , which now pollute every imaginable stretch of sea air and land.[3] That, therefore, the whole cult of buying cars, comparing them, fiddling with them and collecting them turns out to have been as deluded as say smoking tobacco ,drinking alcohol or keeping slaves. That in effect, their whole lives have been a bit of a mistake That they now, with so little time left to enjoy , must give it all up.
It’s a big ask. Especially when incredibly rich industries run incredibly well funded political and media campaigns to tell these same baby boomers that they not only can go on burning fossil fuels, they really ought to- must. Because only that way lies the road to a better yesterday when the world was young. And straight. And white. Here is the challenge facing all of us who call ourselves progressive or educated . We have no idea if we shall succeed We know we will need swimming lessons if we do not,
We at LSS might not want a world government: we might be quite happy with the State we’re in. But you can’t avoid the inevitable. And the hard data, the ineluctable facts from the weather forecasters, suggest that this inevitable may come sooner rather than later, But before we draw our conclusions: what are these facts?
If we break 1.50C global warming (and all the evidence suggests we shall) the effects will be dramatic. There will be alternating cycles of fires and floods in many countries, and for the first time the trend of ever rising food production will go into reverse. The loss of land, and the beginning of floods in coastal cities will lead to rapidly increasing migration pressures. Many would say that is already happening. But it’s as nothing compared to smashing the 20C limit. At that point, sea levels will rise by 40cm by the end of this century, displacing hundreds of millions and wrecking the pattern of the world economy. The surviving lands, wracked by floods and droughts, will start to lose their capacity to produce food at all . The resulting migration pressures will make todays numbers look negligible. As for 30C? It’s too scary to give the full details. But its got something to do with complete collapse of the seasons, fires in the tundras, and social unrest brought about by massive flows of refugees.
In such circumstances a World Government would form very quickly. Because it would be the only body capable of addressing the multiple threats at a global level; Which is the only level at which they can be tackled. History shows that sudden changes in ecology (usually plagues or climate changes) produce truly massive, paradigmatic changes in politics and society . The ending of the Roman Climatic Optimum meant the end of the Ancient world. All its customs, norms and beliefs were washed away in a new Medieval Europe. Similarly it was the Black Death that nailed the coffin of Feudalism, and an utterly new capitalist world was born. The nation state has served us well for hundreds of years. But then-so did cathode ray TVs, plastic musical records and steam trains. So-do we cling to what we’ve got? Or replace it it in anticipation, saving everybody time in the long run?
