We can change the tense when it is uncertain if the statement is true. Compare these examples.
We'd better not go out. The forecast said it's going to rain.
I hope it doesn't rain. ~ It might. The forecast said it was going to rain.
The present tense (is) makes the rain sound more likely. We are more interested in the fact of the rain than in the forecast. The past tense (was) makes the rain less real. We are expressing the idea that it is a forecast, not a fact.
===============================================
Hmm. I notice that "The forecast said..." appears in both examples (similar to "He said he..." in SJ's now-infamous original "minimal pair"


How then can the speaker in the second example above feel that the weather report is any less valid, accurate or real? Is this grammar for real?! Are all grammars this "helpful"?!

Still, I suppose you could argue that it's up to us whether we believe the weathermen...


I get the feeling that remoteness might well enter into reported speech, it's just, the examples so far "demonstrating" it have been somewhat lacking (typical British understatement there!).

Probably the best thing to do is to select starting examples that are worded somewhat differently (can we presume they were so from the grammar books?), rather than spinning one example in various dubious, decontextualized ways, to give the students some idea of how things actually are interpreted in the process of being reported...or is that how we've all been doing it all along, and I just haven't realized? Can even the seemingly simplest things in teaching ever really be a given? This is an instance, I feel, where too much is being merely intimated or assumed rather than thrown open to patient scrutiny.

To put it plainly, I am VERY interested in the PROCESSES by which the person doing the reporting has come to believe and therefore wants (apparently) to say something, and get a little tired of just having to take whatever grammarian's word for it regarding the "required" end product.
