And here’s another reason, dear readers, why I wouldn’t put too much energy into planning for the future or retirement. What? Yes, of course it depends on your age.
I apologize for not being on top of this landmark crossing, but the global sea-surface temperature is once again in "gobsmackingly bananas" territory. The Climate 8-Ball says: uncharted territory dead ahead!
Enjoy your life, while it lasts. 🥳
Breaking News! Code: y-Axis Alert! Yesterday's Nino 3.4 preliminary sea-surface temperature anomaly set a new record high, at 3.48°C above the 1991-2020 baseline. To clearly show this anomaly, the y-axis max was raised to 4.0°C. Attention historians: this is gobsmackingly bananas.

Your 'doom quote' for today: "It’s extraordinary to realise that we are witnessing the great unravelling; the beginning of the end of things. I honestly never thought I’d live to see the start of what sometimes feels like the apocalypse." www.climatecodered.org/2023/06/what...

Models that say we can overshoot 1.5°C & come back down assume: - we will transform our food systems from carbon source to sink - forests and soils keep absorbing 25% of our emissions - oceans keep absorbing another 25% - we enact a vast build-out of tech to pull CO2 back out of the air

Your 'moment of doom' for Oct. 23, 2026 ~ So it goes. "In just a year, the projections for how much temperatures will rise even if governments keep their pledges has risen by two tenths of a degree Celsius" billmckibben.substack.com/p/elections-...
And given these figures, dear audience, UNEP is claiming 2.8 by 2100? ... 🤣🤣
Breaking News! Code UFB!!! It takes 2 weeks to confirm ocean sea surface temperatures and the long wait is finally over. The first day in recorded history with Nino 3.4 SST at or above 30.0°C is now officially on the record. October 7, 2026: 30.000°C. climatereanalyzer.org/clim/sst_dai...

What's especially "problematic" is the continued conflation of the "warming pauze" narrative pushed by climate change deniers and the factual (more than?) doubling of global warming, which is based on real climate science (and acknowledged by NASA, NOAA, WMO etc).
While there is increasingly strong evidence that global warming is accelerating, we need to be careful about how we detect it. Unfortunately a newly published paper on the topic makes a number of mistakes in it approach, as I discuss over at The Climate Brink:

That's something. Buckle up!
Is a daily global surface temperature anomaly more than 2.0°C above the 1850-1900 pre-industrial baseline coming by the end of next week? All the stars will be at the big event. Even the Climate 8-Ball will be there. Don't miss out! Source: www.karstenhaustein.com/climate

Your 'moment of doom' for Oct. 18, 2026 ~ Getting closer. "On one end of the spectrum are the doomers. These are often activists and whistleblowers who feel a genuine sense of dread about imminent disaster, and want to inspire the same alarm in others." www.theguardian.com/environment/...

Your 'doom quote' for today: "For several decades, scientists have consistently warned of a future marked by extreme climatic conditions because of escalating global temperatures caused by ongoing human activities that release harmful GHGs into the atmosphere. Unfortunately, time is up."
Have fun people and enjoy the ride! 🥳🥳
Your 'moment of doom' for Oct. 16, 2026 ~ Seneca cliff "In the face of ever more extreme and unpredictable climate risks, I am coming under pressure to cut my forecasts for the losses that disasters will cause in order to make insurance more affordable – and get my employer more business."

I don’t think retirement planning is really a topic that makes much sense to young people anymore
The region most impacted by shipping desulphurisation shows a net-flux increase more than double the global Earth's Energy Imbalance increase. Both driven by a very strong increase in absorbed sunlight and a RELATIVE decrease in Outgoing Longwave Radiation.

It's been quite something to see certain 'media favorite scientists' wanting to die on the hill of "no acceleration and "the truth is bad enough" Everyone who understands basic physics understands that (more than!) doubling Earth's Energy Imbalance will double the rate of global warming.
"[We] identify a statistically significant doubling of the global warming rate during 2011–2025 (0.40 °C per dec) compared to 1971–2025 (0.20 °C per dec)... The ensemble mean of 26 #climate models fails to capture the observed doubling of the warming rate, simulating a rate of only 0.29 °C per dec"

Your 'moment of doom' for Oct. 12, 2026 ~ Last February. "accurate projections of when global warming will exceed the Paris Agreement’s 1.5 °C threshold are essential for effective climate policy. Existing estimates place this exceedance in the early 2030s..." www.nature.com/articles/s41...

The permafrost in Northwest Territories Canada is melting and beginning to slide into river valleys. The melting is up to 60 m deep! That sure isn't hitting the mainstream media. youtu.be/cIJ_3i3DrUs?...
