I agree with your first statement. In fact, the conversations -- especially the arguments -- may exceed the value of the stories themselves. They often do for me.<p>However, the topic of climate change seems to be a lightning rod for bad arguments. Ones that devolve into comment trees that provide good examples of bad arguments that PG can use in a follow up to "How to Disagree."<p>Good arguments on climate change have occurred on this site. There has been a lot of good debates over the limits of science in the face of complexity, the politicization of science, etc.<p>However, as you put it, there are diminishing returns on this story. The good arguments have been exhausted, and now it is becoming a political gotcha style story. Again, I don't know why I was bothered by this post, but it may be because it was the third or fourth thread on this topic, just with a new small piece of information.<p>(P.S. I do not mean to sound like the arbiter of "Good Arguments.")
