There’s like five Trump republicans on HN. I comment to offer a viewpoint that would otherwise be absent. I don’t need to steel-man democrats’ positions, the media and all the other posters already do that.

> It even seems to come out in your analysis as your source shows that 2023 saw the most days of unhealthy PM2.5 levels since 2012. It went from 724 in 2017, to 822 in 2023. That is a 13.5% increase. It appears you might be falling into the same trap you warn everyone else about.

It went to 822 in 2023 after being between 466 and 657 between 2019 and 2022. Did Trump’s policies cause air quality to get better and then suddenly get worse halfway through the Biden administration?

==There’s like five Trump republicans on HN==

Neither true nor relevant to the comment. The comment was about the propensity to demand more from one side than the other. In this case, you put the onus on Democrats to positively interpret a Republican administration policy that Republican politicians can't even articulate.

==after being between 466 and 657 between 2019 and 2022. Did Trump’s policies cause air quality to get better and then suddenly get worse halfway through the Biden administration?==

No, COVID did that, as other people have explained in this thread. Let's be more specific to try and remove the COVID outliers:

- PM2.5 unhealthy days fell 41% during Obama's term (1,195 unhealthy days in 2008 down to 702 days in 2016).

- PM2.5 unhealthy days increased by 9% from 2017 to 2018, after Trump changed the rules.

It should also be noted that wildfires can have a large impact on PM2.5 levels.

The lies we tell ourselves in order to justify the bullshit.
