I know nothing of climate change. But its complexity is fascinating.
And how should we, our societies, live within biophysical planetary boundaries?

We had that in AD as well with Ninas, I think. Maybe not 10 years but longer than the 3 we just experienced in the 2020s.
Let's be careful tho. Non-chalantly bringing yet another planet into the discussion, the one from 250mio years ago. This one can inform us even less than the younger xxOcenes.

Can't use PETM as analogue – or any other climate before 1mio years ago really. Atmospheric forcing has to act out over the entire system. Which has changed dramatically. Biomes changed, ocean thruways as well, mountain ranges as climate divides, India and East Pacific moved North fast= ENSO, asf. 🖖

I so hope, UK Greens don't jump into coalition with only 15%.
Hope, they wait until a strong & stable 30%. Bc this is the very last chance to turn the system ship around and shouldn't be squandered on the few turbines or cycling paths they'd get with 15% – letting the fickle voters drop to 9%.

Reform-fans want a climate economy but are also addicted to emotional/hate engineering? UK Greens are turning this ship around maybe. From "the boats, the boats!!" to
"the Rich 20%, the Rich 20% !!"
A logical climate-savvy "hate engineering" too, as Kevin's emergency briefing showed multiple times.

Ja. But recall the winters 2023 and 2024? Which drowned UK and northern Germany, destroyed crops and delayed sowing?
These floodings, I think, were due to HungaTonga which strengthened the jetstream, which drove one Iceland Low after the other across 52-54N latitude= lotsa rain, no time to run off.
4 maps for significant temperature change due to H2O vapour from Hunga Tonga explosion for the 3 month groups DJF, MAM, JJA, SON in year 3 to 7 after the explosion. "Significant" means, the authors only plotted those signals that were significantly different to the climatology 2005-2021. For DJF, significant anomaly in °C is: colder in Scandinavia, warmer in North Africa, hotter in South-West Asia, hotter in Canada, cooler in Antarctica. MAM: hotter in East Eurpoe and Russian arctic, cooler in Greenland and East Canada. JJA: warmer in Arctic, cooler in Australia, hotter in West-Antarctica. SON: hotter in Arctic, cooler in Mongolia. Image also shows 4 maps for significant precipitation anomaly in those months groups for year 3-7 after the explosion. DJF increase in Europe, SouthEast Asia and Oceania MAM decrease in central Europe, Southern Canada MAM increase in Australia, Indonesia JJA decrease in East Europe, central America. JJA increase in Southwest and North-West Europe, Australia, South and SouthEast Asia. SON decrease several regions in South America, all over Africa, Indonesia SON increase west Europe, East Canada Read more about the study in the pub-sci article written by the authors themselves: https://theconversation.com/tongas-volcanic-eruption-could-cause-unusual-weather-for-the-rest-of-the-decade-new-study-shows-231074 Paper DOI: 10.1175/JCLI-D-23-0437.1 4 global maps for Hunga Tonga impacts on the jetstream for December to February years 1 to 4 after the explosion. The model projected a very strong jestream across Europe in the first year after the explosion, so 2023-2024. The second year moved the jetstream further South. And it strongly weakened the wind bands across Africa. = less sand in the air = fewer cloud nuclei = worsening the loss of clouds from the shipping fuel regulation regarding SO2 reduction. The second year also strengthened the jet around Antarctica. Maybe leading to strong surface winds which dispersed sea ice = loss. Or aided in keeping it together = gain. The third year gives China's winter months high winds. And the 4th year, no big wind impacts are discernible anymore. That'll be in DJF 2026.

Suffering and near-Grexit was also the fallout of these neoliberal factors, the USA deregulation and EU's arbitrary 3% debt rule.
And Brexit.
The rise of right-wing sadists too.

Funny, no? Somehow, social politics lost in all this. While neoliberals who caused it, intensified their strangling grip

Bad luck with climate change, you know. Paired with bad=neoliberal politics in Finland: privatisation. Here, of a govt body who oversaw and guided all sustainable forest management on the private-owned land.
New management companies need profit growth so fell more than they should and don't replant.
Bar chart by Glen Peters showing Finland's annual Greenhouse Gas Emissions 1990 to 2023. Methane has halved since 1990, from about 10 to 5Mt. N2O is unchanged, about 5Mt. Fossil CO2 first rose from 55 to 72 by 2003, then slowly decreased to 32Mt in year 2023. Forest sink was steady at -22Mt but since 2014, it declined each year, 2018 became positive and in 2023 was about +15Mt. The relative change over 1990 now is +7.8% for Finland.

SR15 chapter 3 tables inform about the change in sectoral risks from 1.5 to 2C like fluvial flood, urban population in drought, and more.
Also % of insect species to lose >50% of their climate home:
at 2C, it's three times the amount vs 1.5C.
And at 3C, it's 49% vs 6%.
Extinction bc🪲🦋move too slowly
Textshot of title and abstract of a Science paper: "The projected effect on insects, vertebrates, and plants of limiting global warming to 1.5°C rather than 2°C" by Warren et al 2018 "Insects are the most diverse group of animals on Earth and are ubiquitous in terrestrial food webs. We have little information about their fate in a changing climate; data are scant for insects compared with other groups of organisms. Warren et al. performed a global-scale analysis of the effects of climate change on insect distribution (see the Perspective by Midgley). For vertebrates and plants, the number of species losing more than half their geographic range by 2100 is halved when warming is limited to 1.5°C, compared with projected losses at 2°C. But for insects, the number is reduced by two-thirds. In the Paris Agreement on Climate Change, the United Nations is pursuing efforts to limit global warming to 1.5°C, whereas earlier aspirations focused on a 2°C limit. With current pledges, corresponding to ~3.2°C warming, climatically determined geographic range losses of >50% are projected in ~49% of insects, 44% of plants, and 26% of vertebrates. At 2°C, this falls to 18% of insects, 16% of plants, and 8% of vertebrates and at 1.5°C, to 6% of insects, 8% of plants, and 4% of vertebrates. When warming is limited to 1.5°C as compared with 2°C, numbers of species projected to lose >50% of their range are reduced by ~66% in insects and by ~50% in plants and vertebrates." Warren et al 2018 is cited as source for numbers on species loss in table 3.5 IPCC SR15 free pdf: https://ueaeprints.uea.ac.uk/id/eprint/67473/2/RWarren_etal_2018_Science_AAM.pdf paper URL: https://www.science.org/doi/10.1126/science.aar3646 table 3.5 in chapter 3 of IPCC SR15 "Summary of projected risks to natural and human systems at 1.5°C and 2°C of global warming, and of the potential to adapt to these risks. Table summarizes the chapter text and with references supporting table entries found in the main chapter text. Fluvial flood: 1.5C sees a 100% increase in affected people over the period 1976-2005. 2C sees a 170% increase. Change from 1.5 to 2: 70% Urban population in drought: 1.5C sees 350mio city dwellers in drought like Tehran today. 2C sees 60-140mio more city dwellers in drought. The table continues with risk comparisons for oceans, coastal systems, food production systems, and human health. source: https://www.ipcc.ch/sr15/chapter/chapter-3/

Diese Obsession, alles über den Preis regeln zu wollen, ist doch pervers, findest Du nich? Es impliziert, dass Leute, deren Lebensstil sowieso schon alle planetaren Grenzen sprengt, es sich weiter leisten können sollen. Wer findet sowas denn toll? 🤔
Echte Sach-Rationen! Für alles. Auch fürs Fliegen.
Screenshot of a Twitter poll from November 2019 posted by me. 263 votes were given. Text: To keep warming at 1.5C, heroic measures are required. To make a 1.5-compatible future work, rapid and fundamental changes are needed in behaviour, in industry and in how our lives are organized. Going on rations for 7-10 years can achieve that. Would you get behind rations? I think it's the best way: 75% I don't see the necessity 4% 10 years of my life? No!! 1% Rations? What did I miss? 20%.

Sediment deposition in some places in German mudflats is slowing down, drowning beneath rising sea levels. Besides damage to biodiv, a loss of mudflats also means stress to dike protection. Categories: “Worse than previously thought” and “Uncertainty is not our friend”
www.nature.com/articles/s43...
2 maps of Germany's North-West coast. One from the paper, the other from the web with pencilled-in names of villages and towns. Most areas are colour-coded as "shallowing" which is a good thing because it means that sediments are accumulating at a higher rate than sealevel rise, thus increasing protection and biodiv. Some areas are categorized as quasi-stable, where sediments accumulate between lower and upper uncertainty range of sealevel rise. 5 areas are red = they're deepening because sediments aren't accumulating at the rate of sea level rise. Around the islands Sylt and Föhr, at the Elbe inlet to Hamburg's port, at Bremerhaven, and near Borkum and Emden on the border to Holland. Another map in the paper shows that only the deepening around islands Sylt and Föhr were known so far. The other locations are coinciding with big port infrastructure.

Oh. Sedimentablagerung im Watt verlangsamt sich an einigen Stellen. Dadurch versinkt zunehmend mehr Watt unterm steigenden Meeresspiegel. Neben Schaden für Biodiv heißt der Wattverlust auch Schutzverlust an Deichen. Kategorien "Worse than previously thought" und "Uncertainty is not our friend."

October in Antarctica from Era5-Land

coordinates extracted like in ClimateReanalyzer: from 66.5S.
The nc-file shows that Era5-Land doesn't apply a strict land-only mask, where it includes the Ross shelf (?) at the plot edges.
2 line charts for October average 2m air temperature in Antarctica since 1950. Era5-Land puts 2025 just above the 2016 value, nearing -35°C. It's a departure from the 1980-2010 average of 3C. Era5 from ClimateReanalyzer puts 2025 at -23.5, almost 2C above the 2016 value. And also a 3C departure from the 1980-2010 average. source: https://cds.climate.copernicus.eu/datasets/reanalysis-era5-land-monthly-means?tab=overview https://climatereanalyzer.org/research_tools/monthly_tseries/ Map of Antarctica with the colour-coded air temperature of October 2025 in Kelvin.

Those 10Gt/a CO2 removal from 2040ff don't require BECCS and DACS.
We today have agency to save our world!
Change our diet (by law), remove cows, sheep, pigs, to give back to nature all land used for animal-sourced food.
The ensuing CO2 drawdown doesn't harm biodiv and requires no energy: 700Gt CO2!
Map of the world with regions highlighted in shades of green denoting the area in use for animal-sourced food. All of Europe is light green, about 50 to 70t per hectare. Southern Brazil is dark green, as well as patches in middle America and China, >130t / hectare. Most other non-desert and non-rainforest regions are very light green, 30t / hectare.

Cutting SO2 emissions increases precipitation? JA!💡
So that's why Cologne in the 1990s flooded al the time!
My girlie-pink marker says,
we're on a SSP1-1.9 pathway ! Who'd have thunk. Progress 🍻🥳
RCP8.5 only achieves this level of SO2 by 2040.
acp.copernicus.org/articles/19/... Lund et al 2019
Line charts of historical and projected aerosol emissions in 4 shared socio-economic pathways. Historical goes up to 2015, projection goes to 2100. SO2 peaked at 140Mt per year in 1980 and reached 115 in year 2015. SSP1-1.9 achieves 73Mt in year 2025, continues steep decline and plateaus from 2045 at 20Mt per year. SSP2-4.5 and RCP8.5 achieve this only by 2040 and then continue slow decline to 20Mt by year 2100. SSP3-7.0 differs from its cousin RCP8.5 and plateaus at an enormous 100Mt SO2 per year all the way to year 2100. https://acp.copernicus.org/articles/19/13827/2019/acp-19-13827-2019.html
