Denial Feels Cozy

Switched to Claude Opus & Sonnet 4.5 for project management. Game changer. The way it synthesizes complexity into clarity is unmatched. Imagine talking to your entire project baseline at once: plans, specs, requirements. And analyzing & reshaping them through dialogue.

Good eye. Notice that bold stroke of 'Arctic Blue' plunging down, clashing violently with the 'Inferno Red'? It’s not just heat; it’s tension. A masterpiece of atmospheric whiplash. But let's not call it a broken jet stream. Let's call it high-contrast art. They are just dancing colours. 🎨❄️🔥

Don't worry about the extreme deviations or the collapsing jet stream. It’s not a planetary emergency, it’s just unintended modern art. We’re not looking at the end of stability, we’re looking at a vibe. They are just dancing colours. Enjoy the show. 🎨🔥❄️ #ClimateCrisis #ArtOrDisaster

Europe has another Earth observation in orbit. ESA's Sentinel-6B, which was launched this morning, will use radar altimetry to measure the sea level rise that comes with a warming climate. @science.esa.int #climate #SeaLevel 🧪

When sound and vision hit perfectly 🎬🎵 This one really surprised me. youtu.be/NUgx3lVVutI?...

The ingredients for even more car soups are plentiful.

How's the climate doing? The oceans are boiling. The poles are melting. The records are burning. And the silence is deafening. #ClimateFuckery

Draft Chapter 10 of Sophie’s Planet, Venus Syndrome & Runaway Climate (mailchi.mp/caa/chapter-...) is an introduction (also available on Substack: jimehansen.substack.com/p/chapter-10...). Quantitative analysis with insights on climate physics will follow.

Looks like our global 'keep calm and carry on' strategy is working perfectly... the oceans are definitely carrying on, right into hotter temperatures. Nothing to see here, just the planet's thermostat breaking.

The oceans are boiling in shades of red. Relax, infinite growth on a finite planet always works out fine.

We, and young people, need help from people who understand the essence of climate science. See Forest versus Trees - columbia.edu/~jeh1/mailin... or its abbreviation - mailchi.mp/caa/seeing-t... also available on my Substack - jimehansen.substack.com/p/seeing-the...

Früher hat man sich in Familien über Religion, Politik oder Geld gestritten. 2025: "DU HAST WAS FÜR EINE HEIZUNG?!?" Verwandtschaft beendet. 🔥❄️

Complex systems vs. the human brain is like sending a Shakespeare play to a toaster. It’ll light up, but no idea what’s going on.

BREAKING Der neue Temperaturrekord für die Türkei #Tuerkiye ist offiziell: 50,5 Grad.

🌊 WHAT DOES +7 SIGMA MEAN? Sea Surface Temperatures in the Northern Hemisphere have reached a 7-sigma anomaly. That’s not just unusual. It’s off the charts. Here's how rare 7σ is; in any system:

The Northern Hemisphere’s oceans just recorded a +7σ sea surface temperature anomaly relative to the 1951–2000 mean. Such a deviation is virtually impossible in a stable system. We're now forcing oceanic change at a pace unseen in thousands of years. #OceanWarming #ClimateCrisis #ClimateFuckery

Made a mistake and watched the news. Oh boi.

Here are the daily warming stripes for global sea-surface temperature anomalies, updated through July 17, 2025. Can you tell that global SSTs are currently 3rd warmest on record for the day?

Today’s planet-sized mood ring glows scarlet over the North Atlantic - seas running up to +9 °C hotter than the 1971-2000 memory. The ocean speaks in steam; hurricanes listen. Laugh at the metaphor now, hear the thunder later. #HotWaterWorld #Anthropocene

Will this be the last Keeling curve upate from NOAA for CO2 at Mauna Loa? June 2025: 429.61 ppm This may be a tragic moment:

Thursday at 3pm PT (special day/time) on Climate Chat: Cause of Extreme North Atlantic Warming in 2023 with @profmattengland.bsky.social. We'll also discuss AMOC & S. Ocean. #ClimateCrisis #AMOC @leonsimons.bsky.social @bikingmzstacey.bsky.social @radsci.bsky.social youtube.com/live/39T7bW7...

Breaking News! Code Yikes! The global 2m surface temperature on July 14th set a new daily record. It was the hottest July 14th since records began in 1940 and possibly the hottest July 14th in the last 120,000 years. The climate 8-ball advises taking the under on 17.0°C. Stay tuned!

"Protocells" have been shown to self-assemble on micrometeorites 🧪 Which is intriguing as organic compounds are sometimes found on meteorites, and micrometeorites would rain down on planets 🌍 throughout the universe www.newscientist.com/article/2486...

"In the mid-2000s, the energy imbalance was about 0.6 watts per square metre (W/m2) on average. In recent years, the average was about 1.3 W/m2. This means the rate at which energy is accumulating near the planet’s surface has doubled."

June 23, 2025 SSTs: North Atlantic blazing, Mediterranean scorching, Western Pacific glowing. Oceans don’t protest, they absorb – until they don’t. #OceanWarming #ClimateCrisis #ClimateFuckery

Deutschland +10 °C über Norm: Die Atmosphäre glüht schon vor, wir müssen nur noch das Grillgut draufwerfen.

MAM 2025 SST anomalies hit +6σ in the North Atlantic, North Sea & Mediterranean. That’s not “a bit unusual”. It’s off the statistical charts. If this were a lab result, you'd rerun the test. But it's the ocean. Expect the unexpected. #Climate #DataMatters #SST

The sea surface temperature of the Northern Hemisphere is now approaching an 8-sigma anomaly — an extraordinary development that suggests we are likely to witness unprecedented and extreme weather events. #ClimateFuckery

wegignorieren (Verb, untr., schwach; Betonung: weg - ig-no-rie-ren) Kunstvoll-komödiantische Disziplin, jeden eindeutig markierten Weg, Plan oder Rat mit majestätischer Gleichgültigkeit zu übersehen und etwas völlig Eigenes anzustellen.

While politicians are still discussing 1.5°C - here is the information on when we will pass 3.0°C.

Your 'moment of doom' for May 14, 2025 ~ Sooner than expected. “We’re witnessing ice dynamics that simply shouldn’t happen on these timescales. The acceleration pattern suggests we’ve potentially crossed a critical threshold that our models didn’t anticipate until the 2040s.”

Yes, Antarctic sea-ice extent has been crashing, with the 3-year running average recently setting a new record low, down nearly 20% from its 2016 peak and more than 10% from its long-term average. The 3-year running average smoothes out short-term anomalies and tells the story:

My, what a delightfully smug kind of toastiness.

Since the dawn of the industrial revolution, a couple of hundred years ago, greenhouse gas forcing - mainly from burning fossil fuels - has more than doubled. Meaning that the ability of the atmosphere to trap heat has significantly increased. Thanks Leon Simons for the graphic!

Looks like the US just pulled the plug on climate research funding. Enjoy the blindfolded cruise - pretty sure these are the Titanic vibes we’ve been waiting for. #NoPlanetB #ClimateCrisis

We will be trying something new at @berkeleyearth.org. Alongside our written monthly climate report, we will be having a short press briefing (~10 mins with slides, followed by Q&A). Tuesday April 15th, 11 AM ET / 8 AM PT / 5 PM CET Register here: us02web.zoom.us/webinar/regi...

ECMWF data shows massive temperature anomalies in March 2025 — deep reds across the Northern Hemisphere, peaking over +10 °C. The planet is screaming. Policy? Still whispering. #ClimateCrisis #HotterEverywhere #GrowthAtAllCosts

The Northern Hemisphere — burning up like the trade wars, but everyone’s too busy scrolling.

Finally stood at the Nürburgring Nordschleife today. For me, it's not just a racetrack – it's the ultimate symbol of speed, challenge, and heritage. Nothing compares.

Massive heat anomalies, record-breaking sea surface temps, and the Northern Hemisphere cooking alive - again. No plans, no urgency, no accountability. We had a planet. We chose profit. #ClimateCrisis

No Bees, No Food. Humanity is on track to learn —through hardship — how complex cause-and-effect relationships truly work.
