Ask HN: HN-like site for climate change discussion?

Many on HN are interested in climate change, but at some point the amount of climate-related submissions might grow so large that it'll be filtered more strongly.

There are some communities on the web that I've run across that talk about climate change, but I haven't found any yet that have the same kind of thought/industry leader participation, deep technical knowledge, and ability for participants to debate constructively.
