David Keith has an audacious plan to slow down global warming. Critics say it poses grave risks.
In addition to actual reporting, the NYT creates newslike ads for the fossil fuels industry. This results in disproportionate attention on high-risk approaches that involve anything other than phasing out fossil fuel use.
When something is finally brought to light in the mainstream media, it leads me to believe that it has been already been happening, for a very, long time, but I am very paranoid, sick individual, and have immersed myself in a lot of noise, drivel online. I don't know anything. I just parrot what I have read or heard
In this case, it hasn't been happening intentionally at a meaningful scale; you'd be able to look up and see the thin haze from it, and use a spectrometer to figure out that it's not water vapor.
What has happened is that ordinary sulphur mixed with fossil fuels has produced particulates lower in the atmosphere. These turn into sulfuric acid when in contact with water, resulting in acid rain. Policies to sharply lower sulfate particle emissions have resulted in that becoming far less of a problem, but also accelerated warming in recent years.
