This is also the UAW position. OTOH the manufacturers are still solidly lined up with the Heritage Foundation et al, who reject the underlying idea of problems associated with hydrocarbon fuels, let alone the CAFE standards in question.

It is a slight exaggeration to say that Dingell "represents Detroit union labor" without mentioning Detroit's automobile manufacturing establishment. In this case, though, it may be true - which is 'to the good', even if insufficient.

If carbon emissions were capped (good luck!), CO2 levels would continue to rise. If If carbon emissions were stopped (dreaming, here...), CO2 levels would take a long time to fall. Global temperatures would continue to rise because the oceans, which moderate climate, will take a decade or more to warm to equilibrium with the present atmosphere. Moreover, Arctic ice would continue to melt, light-colored tundra would continue to darken, etc.

A barely credible hope for 2008 would be slow the rate of increase of emissions, slowing the acceleration of the rise in CO2.

There are ways to stop or reverse warming, but fighting CO2 emissions, even with great success, won't do it in this generation.

Does anyone know of facts that invalidate the above?
If not, then they need to be in our reality base.
