This describes the distortion that shows up in headlines like this one that seem to indicate that there is scientific evidence against the consensus, when really such evidence is very weak. Really, read that article.

However, is the supernova evidence that the Universe is accelerating wrong? No. What's more, even if it were, you can come to the conclusion that the Universe is accelerating now without even using the supernova evidence, so if you want to show that that's wrong, you have a lot more to do than once again raise questions as to whether cosmic evolution of supernovae could explain Hubble Diagram.
