No, people, you are not the result of x.x billion years of successful evolution. Evolution does not seek a result and has no direction. You are a side branch of the primates, of which only one species remains, and you will soon have disappeared completely.

Maximum global sea-ice extent usually occurs in early November. As of October 25th, this year's global sea-ice extent currently ranks 3rd lowest for the day, just 40,000 km² above the record daily low set in 2023. Will 2026 see a new record low maximum? Stay tuned!

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.

CERES just released its August data. Here's the latest update on the 12-month running average for Earth albedo showing a slight increase. The Climate Casino is speculating that it is due to more reflective clouds across the central and eastern Pacific ocean due to El Nino.

On 2.0°C watch. The global temperature anomaly for October 22nd was 1.94°C above the 1850-1900 IPCC pre-industrial baseline and set a new daily record. The Climate 8-Ball is hiding in the corner.

Here's the 30-day running average anomaly for the Niño 3.4 sea-surface temperature. The last 30 days have averaged a record 3.29°C above the 1991-2020 baseline. The forecast is a peak between 3.4°C and 3.5°C in late November. Will we need to extend the y-axis again? Stay tuned!

Back from 4 days "into the woods" and what greets me? Fucking windows. At least this guy has the nerve to say the window is closed. www.cnn.com/2026/10/21/c...

For your information: The claims made in the latest UNEP report are nonsense. By 2050 or 2100, temperatures will rise far more sharply. Currently, CO₂ emissions are rising steadily, and temperatures are rising quadratically. Anything else is just fairy tales about supposed adaptation.

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:

Truly mind-boggling and very scary The 1997-98 El Nino resulted in a global economic hit of $5.7 trillion When we look back on the current hyper El Nino, don't be surprised if there is not much change out of $20 trillion

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

There's excitement in the air! It now looks like the 4-year anomaly will break 1.50°C long before the date the Climate Casino previously gave of November 17th and could possibly break 1.50°C by the end of October! Winning!

For those who may be confused ... The image does not show the 1850-1900 baseline, it uses 1981-2010. Add about 0.8°C to make the adjustment.

Carl LeGuin reposted

The pre-industrial 1850-1900 baseline had 15.5°C as the average annual global maximum temperature. Times have changed. So far this year the planet has seen 160 days above 15.5°C, currently in a tie with 2024 for the most such days, followed by 2023 with 154 and 2025 with 152.

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.

With the planet now heating at 0.4C a decade, the idea the world will be just 2.7C hotter by 2100 is pure fantasy Like 1.5C before it, the 2.7C figure is being used to massively underestimate the dire straits we are in, and to play down the desperate need for action NOW

Vindication of Hansen et al.: "The rate of global warming appears to have accelerated, rising from ∼0.05°C/decade between 1880 and 1970 to ∼0.19°C/decade between 1970 and 2010, and finally to ∼0.36°C/decade between 2010 and 2024"

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)...

Some say early 2030s. Others say 2028. But the math says it already happened in February, 2026. The Climate 8-Ball says there will not be a year in the next 100 years with a temperature anomaly less than 1.5°C above the 1850-1900 pre-industrial baseline.

The more you know ... The 4-year running average for the global temperature anomaly is forecast to break the Paris Limit of 1.5°C over the 1850-1900 pre-industrial baseline on November 17, 2026. We'll be covering the moment. Stay tuned!
