Which can only mean one thing--global warming deniers are bringing the stupid. Let me break it down for everyone who wants to point to snow in New Orleans as proof that global warming isn't happening. This is as simple as I can make it, and I'm typing slowly just to try to help you out.
1. Global warming causes climates to change.Expect the deniers to miss this very simple, yet salient point.
2. When climates change, weather gets weird.
3. When it snows in New Orleans twice in the last five years, that's weird.
You can insert any number of other weather oddities in the last couple of decades to make the same point. You can point to the increased severity of hurricanes, or the increased number of them. You can point to the fact that in 2004, a hurricane appeared in the south Atlantic Ocean, something so rare that scientists didn't know what to call it at the time because they'd never seen it before. Weird. Why? Because humans have had an effect on the global climate, and that makes odd stuff happen. Pretty simple, when you look at it like that.
