Pocket guide to materials discovery calculation methods (repost from the other place)

This is why everyone falls in love with solid state chemistry - first year lab straight out of Harry Potter

Nice visit to the European Commission to discuss AI in materials!

Thanks for all these helpful posts.

I do think this that when laymen deniers use 'saturated' they mean it in a different sense. They mean all the IR is absorbed by CO2 and none is left to absorb, based on simple ideas about absorption coefficients.

E.g. these replies on twitter

Another balloon flight from 2005, this time to 27km

Again CO2 not saturated.

Here is a spectrum of Earth taken from the Mars Global surveyor in 1996. Again the emission in the CO2 band is not zero meaning the atmosphere is not saturated, and 15 micron light is escaping.

Here is the spectrum of earth taken by Nimbus satellite in 1970.

Note the dip at 650 cm-1 due to CO2 absorption, but this dip doesn't go to zero, meaning some 15 micron light escapes.

That measurement has been done by balloons satellites and spacecraft since the 1960s.

Here is the spectrum taken at 31km by balloon in 1966. The CO2 absorption at 650 cm-1 is clearly present. But radiance at 650 cm-1 is not zero. So the atmosphere is not saturated at 31 km.

Lord Toby Young has posted a rehashing of the "CO2 is saturated" meme. It sounds plausible, and some eminent scientists believed it back in history. But we've known for 100 years that the atmosphere isn't saturated with CO2

And one very simple observation shows it beyond doubt.

Another amazing SSCG Christmas Meeting at the University of Birmingham comes to an end, a fascinating range of talks as usual and great to catch up with many friends. Congrats to the organisers! Can't wait for next year!

How you know Christmas has really begun: start of the RSC Solid State Chemistry Christmas Meeting at University of Birmingham

I never normally do this - but got this review today on a paper about XPS fitting of some very topical compounds that literally every paper in the field gets wrong

Just casually strolling past the Ministry of Truth

UCL quad looks best on a crisp winter day
