It's another claim of powerlessness, which is exactly what the 'fossil energy industry' wants people to say - it's demoralizing, paralyzing, and like any disinformation it's a distraction from actually doing something; now we're debating this stuff instead of doing something. So is the victim debate - who is at fault, assessing blame, etc.
Nobody, as a single human being, can accomplish much in any field. Every significant thing humanity does happens in large groups. The good news is, we are hardwired to work in groups - you see it all over, all the time. People naturally organize and work together; think of FOSS projects, for example. And that is what democracy is, and democracy is the most dynamic, effective, changeable method of government in human history.
Let's stop wasting time debating it and get to work. A simple thing to do is to reduce personal climate output. Again, you can't have much effect alone, but humans act together, and we all can do our part. That's why there isn't trash covering the streets - one person can't prevent that, but everyone is putting their garbage in the bin.
I am responsible for the consequences of my actions and words, and for my community - we all are, of course. The victim / blame perspective is the opposite of that - victimhood is a justification / rationalization for a lack of responsibility, for inaction. As anyone with experience of decent management knows, that is the last thing you do. The problem needs to be solved.
