In a post at MSNBC.com ("Greenhouse Simplicities"), Robert J. Samuelson points out "an inconvenient truth" in the global warming debate:
The global-warming debate's great un-mentionable is this: we lack the technology to get from here to there. Just because Arnold Schwarzenegger wants to cut emissions 80 percent below 1990 levels by 2050 doesn't mean it can happen. At best, we might curb emissions growth.
Consider a 2006 study from the International Energy Agency. With present policies, it projected that carbon-dioxide emissions (a main greenhouse gas) would more than double by 2050; developing countries would account for almost 70 percent of the increase. The IEA then simulated an aggressive, global program to cut emissions based on the best available technologies: more solar, wind and biomass; more-efficient cars, appliances and buildings; more nuclear. Under this admitted fantasy, global emissions in 2050 would still slightly exceed 2003 levels.

...the overriding reality seems almost un-American: we simply don't have a solution for this problem. As we debate it, journalists should resist the temptation to portray global warming as a morality tale—as NEWSWEEK did—in which anyone who questions its gravity or proposed solutions may be ridiculed as a fool, a crank or an industry stooge. Dissent is, or should be, the lifeblood of a free society.
As I've commented in the past via this Blog, the questions about "global warming" are serious and cannot be dismissed by fanatics. First, is global warming occurring? Second, if it is occurring, is the phenomenon man-made? Third, if the phenomenenon is man-made, can we do anything about it? Fourth, if we can do anything about it, is the cure (economic recession or, worse, even depression) worse than the disease?
Samuelson believs global warming is occuring. Moroever, anyone who has follwed his writing and career knows he is no right-wing fanatic. However, like Leftie Alexander Cockburn (see previous Posts on this Blog re global warming, under "Categories"-right hand side of page), Samuelson knows flights from reality on this issue when he sees them.
