Over at Real Climate we have been encountering more people like this just within the past day. One wrote in part, “… it seems so very complicated that I cannot support acting on the current knowledge.” In response to this, I said, “How much time have you spent attempting to understand the issues?… and out of curiousity, where are you posting from? Come to think of it, I most certainly would not ask you to act on the current state of your knowledge. In fact, I would rather you didn’t. I would only ask that you don’t get in the way of those who are clearly far more knowledgeable and informed than yourself.” In response to another, I provided a fairly detailed explanation of the greenhouse effect, then in response to someone else I explained the logic of debate on climate change with skeptics. The posts are 143, 155 and 160.
