Received this question in a private message, and I want to answer it in public -- inviting others' thoughts. 

So I have some ideas of starting some teams. Do you have any suggestions as to how to make it productive? 

Britain seems to be making great leaps and bounds. Canada is still a common wealth country. SO I was thinking the greatest angle would be to start ruffling feathers about following their lead. 60-80% by 2050 is the most of any country. Is it in your opinion enough?

The project I'm personally very excited about has to do with the Citizen's Climate Briefing and using that document as the basis for community-wide dialogue (as we're planning to do in the Greater Seattle Climate Dialogues). It's a bit of a twist to invite the whole community to come together -- not so we can tell everyone what they should think, but with the aim of creating respectful, inclusive dialogue that's grounded in the facts.

As for whether 60-80% reductions is enough ... the science is not certain on this yet. There's still a pretty wide range in the amount of temperature rise predicted for a given GHG concentration. So we should be focused on national commitments to stabilize the climate at less than 2deg C of total warming -- which is what really matters -- rather than guessing at what the pollutant concentrations for that would be.
