It's useful for political and media purposes. Some might call it climate propaganda, such as when Al Gore claiming (based on what we was told by top climate scientists) that the arctic would be ice free in 5 years. It's used to make a point and to shock people. It does not appear that any of those same type of doomsday predictions (Gretta, etc.) ever came true. They really do a disservice to the underlining, and very important, issue. Instead of trying to scare people with future predictions of doom, talk about what is happening right now, today, and what will continue to happen. Educate, stop trying to shock and manipulate.
