Oh so you're talking about replications in a very specific field, one completely different from the example you're using elsewhere of climate change.

Your first step is "It's a group of scientists and their work was reviewed, so they are probably all dishonest."

Even that is an unreasonable step. It is very possible for a single person to deceive their peers.

Deductive reasoning like this works so much better for Sherlock Holmes, in fiction. In reality, deductive reasoning tends to re-enforce your biases and ignore the vast possibility space of alternatives.

I didn't pick the example of climate change, but the field is irrelevant. It was just an example. The argument applies equally well regardless of what the hypothetical scientists are inventing data for.

It is possible for a single person to deceive all their peers if you assume unlimited incompetence and naiveity, but that should reduce your faith in what they say just as much!

The argument uses logical induction, not deduction. Induction works fine and is the sort of ordinary reasoning used by people every day. It's normal to trust a group of people less after they were caught lying. If you don't do this, you're the one being irrational, not other people.
