One bad headline that I came across was on the Time web site, www.time.com. The headline was Global Warming Heats Up, http://www.time.com/time/health/. Maybe it's just me, but I feel that Global Warming is a process and it's a no brainer that it's going to heat up as indicated in the name Global Warming. I understand that the author was trying to say that the warming is becoming more intense. The article is a good one though, I would maybe change the headline to show the growing intensity or rate of the warming, not to tell people what they already know.
One headline that I liked was on www.msnbc.com. The story was about how the ground is giving way in New Orleans, causing major problems when trying to rebuild the area. The headline reads: "New Orleans is sinking, study says." I like the headline even though it may have been a no brainer for the person creating it. I think people already assume that this story is about flooding and things that we are familiar with when it comes to New Orleans. But the story being about the land actually sinking, or lowering the elevation level of the city makes this a good headline in my opinion. At first glance of the headline a person might think that they have read this story before, but after realizing what the story is about I think many people would be interested in reading more.
