"How much will $700 billion get you? Roughly speaking, the widely publicized cost of the financial bailout … er, rescue package … is equal to seven Apollo programs, or 70 state-of-the-art atom-smashers.
....
Of course, no comparison is going to be completely accurate. On one hand, the initial price tag will almost certainly come to more than $700 billion, thanks to $110 billion in goodies that were added to the plan to sweeten the deal. On the other hand, the federal government could juggle the mortgage-related securities so adroitly that some of the money is made back. Such spin-offs could produce benefits to offset the bailout's effective cost.

Come to think of it, that's sort of how the space program works, too."

Of course those countries which signed Kyoto have probably spent more than 350 billion dollars [1/2 of 700 billion], and America which hasn't signed has at least spent tens of billions of dollars- on stuff which isn't having any affect upon CO2 emission- other than doing their part of destroying their economies.

Our current economic meltdown will probably do more to cut CO2 then anything else done in total, so the treeweepers so be happy about this.
