The source's lean does matter, as that tends to influence the things that are not said in order to make a point. For example, how much of the predictions that have been made in the past have come true? Does climatology have a different track record of predictions being incorrect than other fields? Are predictions that have been made decades ago and published in the media relevant to the current state of things? Also, as an example of how using failed predictions is fallacious, in the past it was predicted that in the 2000s we'd all have domestic robots in to do cooking and cleaning. There aren't such robots generally available. Does that mean that we can say that robotics today is all bunk and robots don't exist?
