The world has warmed around 1.3C since the mid-1800s. Effectively all of this warming is due to emissions of CO2 and other greenhouse gases. But we'd have experienced substantially more – ~0.6C (0.2C to 1.2C) – if planet-cooling aerosols were not masking part of that warming:

Sooo... In other words, we've caused 1.9-2.5C of warming, we're just masking the fact? People still talk about keeping warming below 1.5 or 2... They're royally confused/behind on the science? FA/FO? Thx for your work. I'm sorry. :(

The magnitude of cooling associated with our emissions of sulfur dioxide and other aerosols is one of the largest uncertainties in the climate system, and has large implications on how much warming we will experience in the future as we clean up pollution and emissions decline:

Do we know how long aerosols (like SO2) hang around in the atmosphere?

So, spray paint may not be as harmful to the atmosphere as, say CFC's?

<intentionally misinterpreting> So basically what you're showing me is we just have to use a BUNCH of aerosols and we'll be good!

What percentage of sunlight do the current level of aerosols reflect back (well, scatter) now, given the assumptions in those plots? I tried reading en.wikipedia.org/wiki/Global_... but got a bit confused -- I assume it depends on the model
