OK, here is my chaotic set of thoughts on all the above... and some wildeyed ideas for winning hearts and minds and changing behaviours.

1. a challenge of this proportion requires an heroic mythos to galvanise public support.  the measures proposed have to be in keeping with an heroic mythos -- and the "New Apollo Project" concept is one way of doing this... however it risks overestimating the appeal of the space program to the current electorate because of the sentimentality w/which two generations of technocrats who dream up policy proposals regard it.  Could backfire in some demographics.

2. the climateers desperately need a novelist and a poet laureate and a good rock band :-) to provide minatory tales, anthems, solidarity songs, text to be typeset on posters and lettered on protest signs, etc.  they also need, in this iconographic age, some kind of logo.  I have told this story before but in Brunner's prescient novel The Sheep Look Up, the environmentalist underground used a very simple grafitti symbol and a slogan.  the symbol was a circle with a flattened X under it (a minimalist skull and bones) and the slogan was "Stop You're Killing Me."  it was easy to spraypaint or sticker.  never underestimate street cred.

3. there is already an appetite among tv viewers for two kinds of shows:  "survivor" shows and "how to" shows.  travelogues are also popular.  if I were a multigazillionaire I would put together a line up of tv shows as follows:
   

"Green My House", a DIY and major remodel show featuring really neat, reasonably sized "green homes" inhabited by happy people who are saving money.  lots of how-to and lifestyle chitchat.
"Survivor:  Earth", a competition show where a limited cast of people tries to get their global footprint down to 1 terron and the audience votes them out if they are not trying hard enough or thinking of all the possible options.
"What Car?" a show about people who live without cars, discussing what tradeoffs they made, why they made this choice, how much money they save, where they live and how local policies make it easier or harder, etc.
"Kewl Green" a show featuring the kewlest green technology around the world, particularly showcasing competition between nation states to make the kewlest lighest cheapest greenest stuff
"Back Story" a show which in each episode takes one familiar product and traces its entire back story and carbon costs from shop shelf to raw materials and forward to disposal, showing true energy costs.
"Traditional Green" an eye-candy travelogue showing how traditional architecture and lifeways worldwide are intelligently adapted to various climates, soil conditions, etc. and how this traditional inventiveness can be applied to materials and applications in other contexts such as western projects.
"climatewatch" a show featuring each episode a Bad and a Good news story about some climate or biosphere issue.
"Going Green" a show featuring enjoyable travelogue to attractive places without car or airplane use -- by bus, rail, bike, ferry, steamboat, etc.
"Real Food" a cooking show about making delicious meals from local/sustainably grown ingredients, each episode filmed in a different region or county.

sure, it's propaganda.  so is 100 percent of what's on TV today.  let's fight back :-)

4. get some comicbook artist or more than one to crank out some graphic novels set in a Green future, very visionary, very ingenious and geek-friendly

5. campaign like hell for lifting restrictions on freedoms where this helps to reduce demand and encourage green behavioural changes.  for example repeal zoning laws that prohibit mixed use;  overrule all CC&Rs that prohibit any energy saving behaviour like hanging laundry, installing passive or PV solar, putting in a green roof, windmill, planting veggies, composting etc.  relax planning dept procedures and allow faster processing for all construction projects using green/low-burn technology;  axe stupid restrictions banning (in my city) houses of a shape other than rectangular, earth houses, etc.  make it easier, not harder, to build state of the art green homes.  lift planning restrictions on homes under 1500 sf to encourage smaller home building;  tax the hell out of homes over 2500 sf.   show the public that some red tape is being cut through and tossed overboard in response to an emergency situation, so that they will be less resentful of taxation or constraint elsewhere.  revoke all bicycle registration requirements and helmet laws, offer legal privilege to cyclists in all collision investigations (there is precedent for this last in at least 2 countries).  make it easy and hasslefree to walk, use PT, and cycle.  make it slowly less convenient, over a period of years, to drive.  require all PT carriers to accept bicycles unboxed (this is a major psychological obstacle to extending bike journeys by bus or rail in the US).

6. the US currently has more prisoners than farmers.  for all nonviolent incarcerees, commute sentence to a lesser number of years of labour on public energy conservation and biotic restoration projects (like restoring wetlands around NOLA to save the enormous costs of bigger and tougher seawalls).  WPA all over again but with a "radical realist" green agenda.

7. institute longhaul taxation in addition to rising fuel prices to discourage the routine and insane transport of perishables over enormous distances.  provide strong tax and subsidy incentives to relocalise agriculture and wean farmers off fossil dependency.

8. revive national rail networks with a major investment for upgrade and overhaul.  provide fed matching funds for all bus and lightrail public transit projects in major cities.  subsidise "try it for a month free" passes for any metro/commute network.

9. cut subsidies to all ag activities that are fossil fuel, fossil water, and soil intensive liquidators.  shame them for what they are -- welfare queens on an unprecedented scale -- and start subsidising land and water stewardship and fossil frugality.

10. mandate K-12 curriculum in energy and biotic literacy, with bioregional literacy required at about the 9th grade level.  no one should graduate from HS without knowing where their city/town/village's water/food/power come from and what it costs in energy to provide.

11. institute a Green competition at all county fairs nationwide -- with prizes for biggest energy or water savings, biggest pesticide or synthofertiliser use reduction, in several categories from 4H to a few hundred acres.  make the prizes worth competing for.

12. institute a Green category for all Science Fairs, for both implementations of existing ideas, new idea prototypes and models, etc. for sustainable tech.

13. stop providing free parking.  period.  anywhere.

14. equalise subsidies for air/road/rail/river with a compensatory preference for rail and river to make up for decades of favouritism for air and road.

15. phase in product labelling showing energy/carbon/GHG costs ("externalities") and miles travelled to shelf, for all consumer goods.  over about 4 years.  after 4 years, mandate such labels and make it an offence for any company larger than a certain size to ship product without such label.

16. relax absurd ag/food laws designed to suppress smallholders, market gardeners, etc.  in general relax constraints on business operations under a fixed size limit, to encourage ingenuity and localisation.  tighten emissions standards and jack up penalties for operations over a certain size threshold.

17. cancel all tax writeoffs for business travel.  provide tax credits for teleconferencing equipment and facilities.

18. of course, stop giving away logging and extraction rights on public lands.  charge very dearly for stripping the larder.

19. tax not only the production and sale of carbon/fossil intensive product, but the advertising of such products, at a swingeing rate.

The difference between theory and practise in practise ...
