Von wie vielen Wissenschaftler:innen habe ich gelesen, sie könnten weinen, sie könnten es nicht verstehen, dass der Ozean nun diesen Temperatursprung gemacht hat.
Forschende werden überwältigt von dem Gebiet ihrer eigenen Expertise – warum? Weil sie Menschen sind.

Now Grant Foster and Stefan Rahmstorf have put out their own papers broadly concurring with Dr Hansen’s. The pace of warming has nearly doubled, due to a mix of albedo shifts & albedo feedbacks, increased destruction/failure of natural sinks..
agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Warm period enhanced global overturning circulation (GOC) - e.g. a stronger AMOC
Poleward heat and salt transport had been much stronger than today leading to strong warming in the high latitudes. Would be another indication that circulations are highly important in regulating surface temperatures
I was recently a guest on the podcast "Project Save the World" hosted by Metta Spencer.
Please have a watch of this exerpt, and maybe the longer video, and tell them what you think in the comments to their video (not here).
Thanks!

I just did a more rigorous computation for increasing Earth's albedo (reflectivity) using 92% efficient mirrors.
To get back to year 2000 albedo levels, we only need a band about 84 km wide (42 km North & South of the equator) of mirrors circling the earth.
The more you know!

![Passing the point of no return

Runaway climate has a new meaning: a climate system pushed beyond the point of no return, when devastating consequences for young people are locked in, impossible to avoid. Below is the latest draft of Chapter 10 of Sophie’s Planet, which will be published in Green Energy Times. For context, it includes the last paragraph of Chapter 9 of Sophie’s Planet.
Meanwhile, as our instrument for the Venus mission was being built, we became involved in investigations of changes in our own planet’s atmosphere. Eventually, our desire to understand those changes overwhelmed our interest in other planets. However, before leaving the planets, let us see what the Goldilocks planets can tell us. That topic is addressed in my first book, Storms of My Grandchildren,[1] where I stumbled and did not distinguish between the Venus Syndrome and runaway climate. For the sake of a coherent scientific explanation, in the next chapter I commit three writer’s sins by: (1) disclosing an event out of chronological order, (2) showing a graph, and (3) including a simple equation. You may choose to skip lightly over a chapter heavy in technical science. However, runaway climate has a new meaning: a climate system pushed beyond the point of no return, with devastating, unavoidable consequences. We must learn from lessons of the past to avoid handing young people a situation out of their control.

Global Warming Has Accelerated Significantly
Foster & @rahmstorf.bsky.social
"The resulting adjusted and thus less “noisy” data show that there has been acceleration with over 98% confidence, with faster warming over the last 10+ years than during any previous decade."
#CO2 233
The slope of this relationship (when CO2 is in log2 space) implies a change in GMST of 7.7°C ± 0.3°C per doubling of CO2—a metric that the authors term the apparent Earth system sensitivity (AESS).
280ppm=13.5°C
560ppm=21.2°C

Interesting stuff!
Tweet today from Ryan Grim of Drop Site. "An unarmed Iranian ship was invited, along with the U.S., to be part of an Indian Naval exercise, and its sailors paraded on land before the president. "The U.S. at the last minute pulled out of the exercise and instead attacked the Iranian ship with a torpedo. Breaking with all norms of civilization and warfare, we then refused to rescue the drowning survivors. The Sri Lanka Navy was left to pull the dead bodies from the water. "I am hard pressed to think of any other nation throughout history that would do something so cowardly and despicable. We are genuinely in a league of our own, and American media — mostly shrugging off the bombing of a girls school and acting as if carpet bombing Tehran is a normal military tactic — is deeply complicit."
Decent summary from Drop Site News. Misses the Australian 'contribution' (three of the submariners were Royal Australian Navy).

I'll post the volume graphics tomorrow, which are *not* at record lows.
