Personally, I believe even Biden-era efforts were insufficient; but all the common arguments to do less against climate change that I encounter regularly fall into the following 3 categories:
1) Selfishness/Freedom at someone elses cost ("why should I suffer from restrictions just to mitigate negative externalities")
2) Poorly informed skepticism toward solar panels, batteries, electric vehicles, frequently involving extremely implausible assumptions about production costs.
3) (Misinformed) dismissal of climate-change consequences ("a few degrees warmer won't hurt too much")
Currently I can't help but think that people will look back on this in a few decades and regard the whole position as obvious idiocy (similarly to the US waging war in Vietnam).
