Was Climate Action Every Really Popular in Europe?

The Paris accord has been painted as a global agreement where the US is the lone dissenter. Now, since the yellow vest protests in Europe, there is reason to wonder whether these protests really represent the popular opinion or whether the majority are for reducing fossil fuel use and otherwise stopping climate change.

If climate action was never really popular, but world governments went along with the Paris accord to take action, then the question is why they went along with it in the first place except as an opportunity to make money.

If it was truly popular but now they are backing off, why? Is it fear of dissenting from the US and Trump? E.g. because they want to appear as diplomatic allies to re-establish open trade without taxation? Are they afraid of popular uprisings like the yellow vests happening anywhere in Europe that policy action is taken for the sake of climate salvation?

How to really understand what European popular attitude toward climate action and the Paris accord are? And/or are most Europeans just unwilling to stand for anything if there is any threat of conflict or economic loss/challenges that could come with it?

Further if the person is right who said they will just give up on climate action as long as the US and/or Trump is in dissent, because then they see no realistic possibility of making a difference, then does that reflect a truly deferential will toward the US as a leader, or are they only pretending to accept US leadership on something like climate to be able to exercise reactionary power vis-a-vis whatever the US does to lead?
