On July 30, 2022, I wrote the article below, where I concluded: "What appears to be the case from these recent articles is that it’s not the sources that are driving this rise, it’s the degraded hydroxyl radical sink and loss of other natural sinks." climatecasino.net/2022/07/is-t...

The presumed upcoming El Nino will help cement and quantify global warming acceleration, showing that 2C global warming is likely to be reached in the 2030s, not at midcentury.

IPCC models might deem it highly unlikely, but Global warming reaching +2.0°C next decade is much more likely when considering NASA CERES satellite observations based climate forcings and feedbacks. We'd better assume observations are more indicative of reality than models alone:

The strategy against Europe is always "divide and conquer." Whether it's Russian disinformation or Big Tech lobbying, the goal is to break our regulatory power. They hate the EU because it works. If we stay united, they lose. If we fracture, they own us

Just out today: The report “A Nordic Perspective on AMOC Tipping” reviews the current state of science on the risk of Atlantic Meridional Overturning Circulation (#AMOC) shutdown. 🌊 Conclusion: it's "a serious risk which requires a dedicated risk management framework". pub.norden.org/temanord2026...

Another insightful visualization of when we could reach daily, monthly and annual temperature marks if the warming acceleration continues (not a prediction, but not impossible either). Rees is great a putting a lot of information on a (relatively) comprehensible single graph!

Eikö metsäteollisuus voisi viimein alkaa laittaa tuotantopalettiaan uusiksi? Muuttaa sekä pää- että sivuvirtojen käyttöään, vähentää puun polttamista energiaksi ja siten vastata ilmeiseen tarpeeseen vähentää hakkuita Suomessa? Toki se vaatii työtä, mutta lopussa kiitos seisoo. #talous

These Epstein files are so horrific that we could see Tehran carpet-bombed, Obama arrested and martial law declared in Minneapolis in the next few days.

Tässä se on: hallitus on pysäyttänyt Suomen talouden n. 4 mrd. euron nettosopeutuksella. Velkajarrusopimus ja EU-säännöt vaativat tulevalle hallituskaudelle 10 mrd. euroa lisäsopeutusta juuri tällä VTV:n laskutavalla. Olemme valmiiksi jo talouskriisissä. Onnea Suomi! #talous #politiikka

Arctic sea-ice extent is still lowest on record for the date as of January 24th, about 63,000 km² below the previous record low for the date, set in 2018. Will 2026 beat the record low maximum set just last year? The Climate 8-Ball is busy stocking its bunker.

En järkyty näistä valtiollisista murhavideoista enää, vaan pidän niitä opetusmateriaalina siitä, mitä tuleman Suomessakin tällä menolla pitää. Ihmisen henki on lopulta heikosti kiinni, kun hyvinvointiyhteiskunta murenee ympäriltä ja mielivallasta tulee arkista. #yhteiskunta

On syytä muistaa, että hallituksessamme istuvat perussuomalaiset ja kokoomus fanittavat Trumpin autoritaarista hallintoa.

Solidarity, particularly across race and class, is Kryptonite for authoritarian regimes. They can only thrive when their us v. them framing is adopted by society at large, and they join as active or passive collaborators with the regime. So the only response they have is to raise the cost of unity

Ylikulutuksen ratkaiseminen vaatii talousjärjestelmän haitallisten kannustimien huolellista purkamista ja tuotannon ohjaamista yhteiseen hyvinvointiin. Konkretia tähän keskusteluun on äärimmäisen tervetullutta. Suomessa meillä on @bios.fi, joka puurtaa aiheen parissa maailmanluokan tasolla!

Ahdistaako kun amerikkalaiset teloittavat omia kansalaisiaan kaduille? Kannattaa muistaa, että vaikka tilanne USA:ssa on eskaloitunut, niin se ei ole syntynyt tyhjästä. Taustalla useamman vuoden propaganda, jossa ihmis- ja perusoikeuksia on romutettu mm. "maahanmuuton", ....

A crazy amount of heat has accumulated in the Equatorial Pacific Ocean over the past two months. Hold on to your hats when this reaches the surface with the next El Niño. Y-axis shows depth, X-axis shows degree longitude (one degree equals 111 km) and colors temp anomalies. @noaa.gov PMEL data

Näinhän se on. Puolustusselonteossa ei haluttu nähdä tosiasioita. Eikä näköjään haluta nähdä vieläkään. Tosiasia on se, että Yhdysvaltoihin ei voi enää luottaa. Ei ole voinut vuoden 2016 jälkeen. Eli kymmenen vuotta. Trump ei ole tauti vaan oire. Tämä pitää ymmärtää. www.hs.fi/suomi/art-20...

We could see as much global warming in the thirty years from 2020 to 2050, as over the preceding 90 years! The world is warming faster now than at any time in known history of our planet. See Generations of Global Warming: www.youtube.com/live/zmllNBR...

In a sane world, this would be front page news everywhere. But it will hardly be covered anywhere. The North Pacific Ocean surface warmed over twice as much over the past 15 years than it did over the preceding 156 years. That's an increase in warming rate of >2000%!

2025 was the hottest year on record for ocean heat content. Unfortunately, we now say this every year. 🥹 "In addition to setting a new record in 2025, the global ocean continues to show sustained and intensified warming." + #OpenAccess Study: doi.org/10.1007/s003... + Data: www.ocean.iap.ac.cn

A short thread about the back story behind our new study. 🌊 A pile of evidence suggests the Atlantic overturning #AMOC (and its surface branch North Atlantic Current) has slowed. But some colleagues were sceptical, arguing the Norwegian Current and its deep return flow haven't slowed. 1/6

2️⃣ Professor @kevinclimate.bsky.social: we're using up the carbon budget for staying under 2°C at 0.7% every single month, with a small but very real risk we could reach a catastrophic 4°C by 2100. There are huge benefits for the majority if we address climate change. www.nebriefing.org/take-action

One of my New Year's resolutions is to make data more accessible. Also to protect it from data purges by e.g. anthropogenic climate change-denying regimes.. Find the data uploaded to GitHub here: github.com/LeonSimons/N...

Trump just said what it is all about. The sooner the world sheds its addiction to fossil fuels, the better. The alternatives are available, plentiful and cheaper.

I've had an appalled IPCC employee reach out to me about the gatekeeping of science by petrostate representatives. They told me that statements about '1.5°C being breached in the early 2030s in all scenarios' were scrapped from the IPCC report, during a huddle... Some scientists were crying.

There is a lot of evidence of the IPCC process leading to gatekeeping of inconvenient information, especially in the summaries for policymakers (which few read beyond). See for example the removal of sulphur aerosol cooling from AR6 SYR SPM: enb.iisd.org/58th-session...

It looks like the correct number for a Category 6 hurricane is 200mph sustained winds or higher. That's yet to happen in the Atlantic, where the record is 190mph, but has happened in the Pacific. Cat 2: 96 - 110 Cat 3: 111 - 129 Cat 4: 130 - 156 Cat 5: 157 - 199 Cat 6: 200+

Call me paranoid, but reading between the lines of this interview of Finnish Prime Minister fills me with dread: that the Amazing Spinelessman is preparing to abandon #Ukraine, because his government crashed Finland's economy & a “peace” would lift it before the elections. www.is.fi/politiikka/a...

Kova haastattelu. Orpon retorinen strategia avautuu: 1) kätke hallituksen rasismi, 2) väitä, ettei sopeutukselle ole vaihtoehtoa, 3) väitä, että sopeutus ei ole heikon kasvun syy, vaan Suomen ulkopuoliset tekijät, 4) kerro, että olet itse innostaja 5) kiellä hyvinvointivaltion alasajo. #politiikka

Based on the 11-year running mean (and on Earth's Energy Imbalance), the near-term rate of warming could turn out much higher than the linear 2010-2025 extrapolation. The next El Niño peak will be very informative for the rate of global warming, as @drjamesehansen.bsky.social points out:

Puhumattakaan kasvavasti maahanmuuttajataustaisesta nuorisosta ennätysnopeasti vanhenevassa maassa, jossa hallitus normalisoi rasismia. Uskomatonta omaan jalkaan ampumista. Kuten olen usein sanonut: maanpuolustustahto oli tärkeimpiä syitä, miksi muutin mielipiteitäni oikealta vasemmalle.

Nämä "talousosaajamme" tuovat mieleen taistolaiset Neuvostoliiton viimeisinä päivinä. Ilmeisenkään edessä ei myönnetä ideologian valuvikoja. Vaihtuvia selityksiä sinkoilee siihen malliin, ettei kuuntelija enää tiedä, pitäisikö itseä vai nauraa. Aivan kuin kukaan ei olisi varoittanut nykytilastamme.

The closer we get to 2035 and 2050, the more empty promises are presented for what they were. Words are cheap, pledges about policies ten election cycles in the future are proving to be worse than useless.

Have you also asked an AI chatbot about climate and found the answer to be quite good? Maybe that is because it was you who asked. Some AI (e.g. Grok) tailors their response to suit your beliefs. It’s called ‘AI sycophancy’ (a new word I just learned.) globalwitness.org/en/campaigns...

2/7 Hallitus puhuu 10 miljardin sopeutuksesta. VTV:n arvion mukaan oikea sopeutus on murto-osan siitä: 3,6 miljardia € vuoden 2027 tasolla. Syy on se, että hallitus ei huomioi luvussaan mm. kaikkia menolisäyksiään. Pysyvä sopeutus jää vielä pienemmäksi, kun puolustusmenojen nosto astuu voimaan 2029.

Vrt. Rinteen/Marinin hallituksen velanotto oli kokonaisuutena, siis yhteensä, n. 40 mrd €. Talous osaajien hallitus *ylittää tavoitteensa* 30 mrd eurolla.

Tästäkin tulee suomalaisille veronmaksajille lähes täysin varmasti iso lasku.

Breaking News! Code Yikes! Not only was yesterday's Arctic sea-ice extent a record low for the day, yesterday's extent beat every year prior to 2024 by over half a million square kilometers. The Arctic currently has a streak of 21 straight days of record low sea-ice extent.

I'm certain we're already passed 1.5C & just waiting for the running Avg to catch up. I share @leonsimons.com view that it's patiently stupid to be looking through the rear view mirror The climate science community needs to up its game This exellent graph is from @reescreverem1.bsky.social

The Trump regime wants to dismantle a world leading climate research center. Why? Because the US has become a petrostate where the government has been captured by fossil fuel interests. They’re calling climate science “green new scam research”, in full denial of reality. 🤯
