Nasa scientific vizualization laboratory have created this great new animation, looking at sources of CO2 into the atmosphere in 2021. It’s a mix of observations and modelling. The great thing is that it colours CO2 by source, giving us a fantastic insight into the behaviour of an invisible gas.

I was asked for comment for this piece by the Carbon Brief, which summarises the whole thing nicely, and I put up a couple of TikTok videos (see below) which got around a bit.
