The controversy is over whether we should learn more about it and take appropriate actions, or ignore it. This fundamental disagreement makes it a controversial topic.
Reminds me of the when all the catholic priests were molesting kids and being moved around instead of outed and prosecuted. This was also a controversial topic too for the same reasons. Some people wanted to take action, while other (more powerful) people wanted to ignore it.
It’s true. In the US reality itself has become controversial. Maybe the oligarchs’ lies are just as valid as objective reality? Who can say!
I see no controversy there, yes we should take some very strong action since we literally crap where we live and we only have 1 self-contained room for it all, the debate (not controversy) should be about which steps are most efficient, while not ruining the economy albeit some acceptable setback is probably unavoidable.
So no to dumb fuckery EU did with biofuels (for which vast rainforests in ie Borneo had to be cut down forever), no destruction of local automotive industry while rest of the world couldn't care less. And Yes to many other, saner activities, of which some are done, in some places.
In the US, sure.
In Australia we established a Royal Commission into Institutional Responses to Child Sexual Abuse, looked at all the schools and institutions regardless of creed (and, it turned out, the Christian Brothers were the clear worst of the worst - although few came away unscathed) and then put a senior Vatican Cardinal on trial.
TBH it's been a lot harder to get the worst carbon offenders under close scrutiny in a very public eye.
