Steve, I would just add that thirty years ago the intellectuals who had the ear of the media spread fear that we would be entering an ice age within ten - twenty years using some of the same words such as irrefutable, man made etc.....

Is man possibly contributing to this "cycle of global warming"? Quite possilbe but not nearly as much as one massive California forest fire or erruption of a Volcano. Would it be good to clean our air as much as we can? You betcha but isn't it interesting that folks like fatwolit and Al Gore, Pelosi and Buffett who scream the loudest all have a financial stake in a company that is there not only to clean the air but in making money off the fear they are spreading.

There are some folks you cannot get through to but you made a valiant try
