There it is.  The half joking comments by the nut wing that once the arctic ice is gone, oil tankers will have shorter routes.  And think of all that Siberian and Canadian arctic coastal and offshore oil that will become available.

They neglect the important fact, that those past ice ages were caused by natural phenomena like volcanoes and meteor strikes.

This current climate disaster IS a result of human activity and thus preventable.

Limbaugh's argument is very powerful, maybe he has switched his drug intake to more natural sources.  No more oxycontin rants?  Hehey.

What he should say about arctic ice and ocean currents is that when the gulf stream slows the heating effect in the northern regions will be diminished and the ice restored.  Nature is self correcting.  Look for that next.

Of course we can still defeat that argument against green energy by pointing out that it is economically and culturally beneficial to halt the human contribution to this global climate emergency.

In purely capitalist terms, the cost in reduced economic growth from storm, drought,energy wars, and rising ocean levels justifies the shift to green energy that eliminates the human contribution to global climate change from greenhouse gas emmisions.

It's the best course for business as well as each traveler on spaceship earth.
