This ultimately led me to this article (about the reactions of politicians), and then on to this article from science blogs that has both an argument for speaking out, a scientists, and has a transcript from President Obama's press conference where he answers a question about climate change (and does a pretty decent job of this: "...we can’t attribute any particular weather event to climate change. What we do know is the temperature around the globe is increasing faster than was predicted even 10 years ago. We do know that the Arctic ice cap is melting faster than was predicted even five years ago. We do know that there have been extraordinarily — there have been an extraordinarily large number of severe weather events here in North America, but also around the globe."). And of course, there's an article from Francis and Vavrus in Geophysical Review Letters (2012) that talks about Arctic Amplification (more extreme weather as a result of less ice in the Arctic).
In short, there is an awful lot of talk - in the mainstream media, in politics, on TV, the radio, blogs - about climate change in the wake of Sandy. Whether this becomes a tipping point, we'll see,
