My latest on The Climate Brink:

Is this the most embarrassing error in the DOE Climate Working Group Report?

The DOE CWG authors confuse detection and attribution with emergence.

Last week the German Meteorological Society warned that "the 3-degree limit could be exceeded as early as 2050".

While not possible to fully rule out, the assessed warming scenarios we published in the IPCC AR6 report find this to be extremely unlikely.

Its Doors Open Days at @uni-of-edinburgh.bsky.social!

All weekend, find Euclideans at the Royal Observatory Edinburgh and learn more about how the #Euclid mission will transform our understanding of the Dark Universe. 🌀🔭🌌 #ROEopen
A small crowd of people, including members of the public and University of Edinburgh scientists, chatting and standing around the Euclid pop up exhibition. This includes a large display of Euclid’s first mosaic, containing lots of stars and galaxies, in the background against the wall. On the right side of the room is a small model of the Euclid spacecraft, as well as tabletop activities.

The people I work with are not stupid people and our climate predictions of 30 years ago of global warming have proved to be accurate. Just saying. www.bbc.co.uk/news/live/cp...

I'm not quite sure what you're suggesting then. I don't think anyone argues that energy balance estimates aren't useful. It's mostly a suggestion that Nic Lewis has tended to be over-confident about his analyses and that - as many have suggested - these estimates have tended to be biased low.

But it's not just uniform vs Jeffreys. There are other priors and there are other ways to estimate ECS. As Andrew points out, if your method suggest a good chance of the ECS being < 2K, then there's probably an issue with the method, or it's at least worth considering this.

The evidence is public. Martz thinks that "most of the warming could be natural" 🤦. (This isn't a surprise, of course).

1/ A rising telescope under a rising Sun and Moon! 🔭☀️🌕

This montage is a kaleidoscope of moments from the construction of our Extremely Large Telescope.

Creating this #ELT collage took Boris Häußler, an ESO astronomer in Chile, years of meticulous planning.
The image shows seven hexagonal images put together like a flower. All the images show the Extremely Large Telescope (ELT) in front of an orange sun or moon rise. All the hexagons are dated and show the ELT assembly at the specific date.

I used to think that climate change was a somewhat unique example of a topic that was challenging to discuss publicly. The last few years have made me realise that it's not just climate change; we seem incapable of having nuanced discussions about any complex/contentious topic.

Caught a bus today to pick up my car and wanted to go to the last stop. When we got to the second last, the bus driver checked if I wanted to get off. When we got to the last stop, I asked why and was told it's because most people who go to the last stop have fallen asleep and missed their stop :-)

He is a Viscount which - I think - is higher than a Lord. However, rather confusingly, might also be referred to as Lord ...., when being addressed.

If you would like to watch a rather blunt YouTube videos about why Ridley - like Monckton - is not someone whose views you should take seriously, this one is pretty good. www.youtube.com/watch?v=C-gd...

I should have added that at about the same time as this, maybe even roughly the same day, I was involved in "discussions" with another Viscount (Ridley) which led me to muse that I was "annoying" two Viscounts at the same time.
