Oisko liikaa vaadittu, että jos haluaa syödä eläimiä, niin maksaisi niistä sitten täyden hinnan?
Ilman niiden kuuluisien veronmaksajien tukia.

A brown penguin chick of some kind. It looks very much like a man in a suit. It is bedraggled and miserable

Made it to Friday but at what cost

Mitä, jos Venäjän varjolaivastoon kuuluvalla öljytankkerilla tapahtuisi onnettomuus? Kuten teettämämme mallinnus osoittaa, jälki olisi tuhoisaa.

Öljyä päätyisi koko Helsingin ja Espoon edustalle ja aiheuttaisi mittavaa tuhoa lukuisilla luonnonsuojelualueilla.

Flawed economic models mean climate crisis could crash global economy, experts warn States and financial bodies using modelling that ignores shocks from extreme weather and climate tipping points

Fundamentally flawed economic models mean #climatecrisis could crash global economy, experts warn

- Shocks from extreme weather disasters and tipping points are entirely missed by the current models used by governments and financial institutions

Iran’s biggest centres of protest are also experiencing extreme pollution and water shortages Shortages of water and power as well as rising air pollution in Iran are at the centre of why citizens are telling their government they want change.

'Beneath the country’s political and economic crisis lies a more destabilising force that is still largely missing from international analysis: environmental breakdown. ... Protests increasingly erupt in areas where there is groundwater collapse, land subsidence and water rationing.'

Suomen valtio aikoo hakata satoja hehtaareja arvokasta metsää, sanovat järjestöt – lista kohteista julki Orpon (kok.) hallituksen päättämät vanhojen metsien kriteerit ohjaavat nyt Metsähallituksen hakkuita.

Uutisen pitäisi olla se, että tämä ei ole uutinen. Edelleen sama touhu, jossa jokainen pienikin metsätilkku on ihan pakko hakata, tai tulevat heinäsirkat, nälänhätä ja maailmanloppu.

New from us: EU CO2 emissions fell only 0.8% in 2025, the second year in a row that the bloc has fallen short of its targets. Adverse weather played a big role but underlying issues are slow progress on transport and buildings electrification and wind power buildout.

World enters era of ‘global water bankruptcy’ The world has moved beyond a water crisis and into a state of global water bankruptcy, says a new flagship report released on Tuesday by UN researchers.

"For much of the world, ‘normal’ is gone" – Humans are "withdrawing and polluting water beyond renewable inflows and safe depletion limits" and causing irreversible damage to wetlands and lakes that could have helped with restoration.

Number of people living in extreme heat to double by 2050 if 2C rise occurs, study finds Scientists expect 41% of the projected global population to face the extremes, with ‘no part of the world’ immune

🔥3.8 billion people will be exposed to extreme heat by 2050. Great to see my @smithschool.ox.ac.uk colleague and teacher Radhika Khosla interviewed by @jonathan-watts.bsky.social for the Guardian.

Australia’s worst heatwave since black summer made five times more likely by global heating, analysis finds Extreme heat ‘is getting worse and whether we like it or not … there’s ultimately a limit to what we can actually physically cope with,’ scientist says

Forest loss intensifies meteorological drought in more than half of Earth’s climate zones Forest loss increases the risk of meteorological drought more in boreal zones than in the tropics.

Forest loss is shown to exacerbate meteorological drought globally, with boreal regions most affected. Urgent conservation and restoration are needed.

'We just want to be left alone': Greenlanders on Trump's takeover threats The BBC's Europe Editor Katya Adler visits the Artic island to ask what people think of the US president's plans.

For those thinking that climate change can take a back seat while this other geopolitical mess is addressed - think again. Climate change is in part why Greenland has become so attractive to Pumpkin and his lot. bbc.com/news/videos/...

Metsä Group myönsi: luonnonmetsän puut menivät sellukattilaan | Greenpeace Metsähallitus hakkasi Ylimmäisensuon luonnonmetsän viime perjantaina. Metsä Group myönsi viimein, että yhtiö osti puuta luonnonmetsän hakkuista.

Tällä bulkkitaloudella se varmasti saadaan Suomen talous nousuun. Metsähallitus vähät välittää mitä hakkaa, ostajaa ei voisi vähempää kiinnostaa mitä ostaa. Valtakunnassa kaikki hyvin.

So much fun

Thrilled to share I’ll get paid for two years to deepen my existential dread about climate collapse—thanks to the Nessling Foundation! Starting end of 2026 at @bios.fi, I’ll explore how an AMOC collapse could reshape Finland’s society, with a focus on food production.

"The environmental crisis should be integrated as comprehensively as possible into foresight practices and preparedness, rather than treated as a separate domain." A quote from Emma Hakala and Helmi Räisänen, from FIIA Briefing Paper 423: Environment-related risks in comprehensive security: A framework for foresight and preparedness.

📝New FIIA Briefing Paper

Environment-related risks can trigger sudden, cascading effects across sectors and borders. @ezhakala.bsky.social and @helmiraisanen.bsky.social explore environment-related risks as part of comprehensive security and discuss ways to prepare for them.

Sybren Drijfhout (KNMI) showing that current observed AMOC trends align with high emission models (that all have AMOC collapse in the upcoming 2 centuries).

Great, intense conference during the Nordic Tipping Week in Helsinki and Rovaniemi 🇫🇮 last week.

Climate scientists, fisheries experts, social researchers, and policy makers came together to discuss what an #AMOC weakening or collapse could mean for the Nordic region and the rest of the world.

These iconic corals are nearly extinct due to heatwaves: can they be saved? Florida’s primary reef-building corals have been declared ‘functionally extinct’ — prompting a shift in conservation strategies.

Hyvää alkanutta työviikkoa. Kaikki on loistavasti.

"Two iconic corals that have flourished across Florida’s 560-kilometre-long reef for more than 10,000 years are now ‘functionally extinct’ following the record-breaking 2023 heatwave." www.nature.com/articles/d41...

Just attended Nordic Tipping Week to discuss the latest science on the AMOC tipping point and its societal impacts. Now I’m feeling some serious post-conference anguish. Being back in a world pretending everything’s normal is exhausting. The cognitive dissonance is heavy.

New study by Falkena et al. shows that most climate models
don’t capture the established key mechanism that can destabilize the North Atlantic subpolar gyre. Those models that get it predict abrupt subpolar gyre changes in coming decades 😳.

Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says Analysis of 25 years of evidence shows most schemes are poor quality and fail to lower emissions

“‘We must stop expecting carbon offsetting to work at scale,’ said Stephen Lezak, a researcher at the University of Oxford’s Smith School. ‘We have assessed 25 years of evidence and almost everything up until this point has failed.’” www.theguardian.com/environment/...

Transboundary conflict from surface water scarcity under climate change - Nature Communications Transboundary river basins (TRBs) are at an increasing risk of water scarcity-induced conflicts. Nearly 40% of global TRBs could face such conflicts by 2050, but measures such as intra-basin cooperation could reduce this proportion to less than 10%.

Nearly 40% of global transboundart river basins could face potential conflicts driven by water scarcity in 2041–2050, with hotspots in Africa, southern and central Asia, the Middle East, and North America
