NASA will soon launch a satellite to directly monitor for the locations of ground level point sources of CO2. http://www.nasa.gov/topics/earth/features/oco-20081112.html
I suggest a moratorium on all of the "lets 'STOP' Global Warming" hoopla and gather some meaningful data. Let's find out where this evil CO2 is coming from and develop programs and incentives to reduce the actual sources.
If U.S. autos are a huge source, there is data to support moving to something else. If the U.S. Electrical power industry is one of the major sources, there is additional emphasis to stop pi**ing away money on Tokamaks and get serious about developing truly net positive fusion.
If the problem is China's factories or power generation, well the Chinese can clean up their mess.
As an incentive, let's suppose Chinese factories and power generation is a large component of man-made emissions. Consuming nations should make a decision if they can produce the goods they purchase from this high emission region at lower emissions. If so, imports from high per item emission producers should be reduced in favor of local production in lower emission areas.
One last comment, just because it bothered me so.
I recently saw the remake of the classic Sci-Fi B movie "The day the Earth stood still". I was disturbed by the omission of an epilogue which described the results of the closing scenes of the movie.
"... and with the loss of electrical and other power sources, industry shutdown, and all that depended upon mechanization died with it. Within weeks Billions of the Earth's inhabitants were starving. The cities became hunter killer grounds as those who could, took from those unable to protect themselves.
Within months humanity had retreated to a Medieval life style, as disease and starvation continued to reduce the numbers of humanity to a tiny fraction of those alive on the day of landing.
The forests were denuded as those left alive sought fuel to guard against the cold of the Northern Latitudes. Coal once again became a primary fuel source. Recovered from the ground as it had been 400 years before, by children working until their early deaths."
Yeah, just what I want for MY children! (Sarcasm intended)
To those who thought the ending of that movie was nirvana, I have a suggestion. Pool you money, buy a small country, move there and institute your "no carbon emission" fantasy. After your gone we'll come around to reclaim the land if we feel like we need it.
I for one DO NOT want to see my childrens future (economic, educational, or standard of living) eviscerated to fulfill someone else desire to "fight Global Warming".
Instead of generating completely unrealistic Carbon caps and Carbon reduction targets, which in reality will simply become the next economic weapon (and a HUGE moneymaker for those trading in "carbon credits"). Let's get serious about fixing the problem.
We need a new, continuous, throttleable energy source and a new high energy density, safe liquid fuel of low or 0 carbon emission. I'd feel much better about my standard of living being decimated if the reduction was being spent to develop these things, than to "conserve our way to Carbon nirvana".
In case you haven't noticed, you can't conserve your way to prosperity.
