It seems you are starting your argument with the premise that we aren't responsible, and then concluding that we aren't responsible.

My starting premise is God, and with penitent humility, God is my foregone conclusion.

You cannot have your conclusion as one of your premises, because that's just a circular argument.

It's not an argument of any type. It's a humble acknowledgment of He who is in control.

That's not what I said [that "all prophets are heretics"].

What you said, specifically, was, "That's all assuming you know god's plan which is heretical." A prophet is someone who knows God's plan as it applies to many people. So yes, you claimed that prophets are heretics. Now I'm no prophet, but like any Christian, I maintain a relationship with God and I read Scripture, so I know God's plan to the limited extent He reveals it to me. That's not heresy.

somebody doesn't need to be christian to hold true beliefs or have valid arguments

You're either with God or you're against God. Anyone who sides with Satan cannot be trusted. They might indeed make true statements or valid arguments now and then, but they can only do so in service of the Beast, attempting to lead others down the road to Hell.

Second, it's an argument from authority.

Nothing wrong with respecting authorities, and trusting their assessments. God is, after all, the Lord of Lords and King of Kings.

Third, it's a setup for a no true scottsman fallacy, because no matter who I bring up you'll call them a false christian because you've already defined a christian to be somebody who holds your own views exactly.

I don't deny there's a non-zero chance of the discussion playing out that way, but in practice I think there are just about zero climate scientists who call themselves Christians yet also think human beings could have caused climate change. If you find any examples, I'll be rather curious what denominations they affiliate with. There are certainly a few crazy leftist denominations out there that seem to have fully rejected God, so it's possible a few such climate scientists exist. If they do, and you were to find them, of course you're right that I'd have to question their church's Statement of Faith. But that's no fallacy; it's just recognizing that Christianity is incompatible with the premise that humans could possibly cause climate change.

This question is a ridiculous goal post that quite clearly on wheels, able to move the moment I name a name.

My only goal post is your acceptance of Christ.
