Yeah, it’s not obvious how to relate all the figures to one another. The article you shared says ”Around 2.4% of global CO2 emissions come from aviation” which is consistent with the data in the article I linked to as well.
I’ve not seen a ”percentage of global warming” figure for the IT industry but when it comes to data centers, CO2 is also just one aspect of it. Mineral mining, transportation (including flights), deliveries to and from facilities, massive water consumption, etceteras. It’s certainly up there.
