Warren Buffett, typical hypocritical left-winger: He suggests that greenhouse emissions are bad; also brags about his company's ownership (and his own heavy use) of a private jet business

From Warren Buffett's Berkshire Hathaway 2010 shareholder letter (dated February 26, 2011) here:

Last year BNSF moved each ton of freight it carried a record 500 miles on a single gallon of diesel fuel. That’s three times more fuel-efficient than trucking is, which means our railroad owns an important advantage in operating costs. Concurrently, our country gains because of reduced greenhouse emissions and a much smaller need for imported oil. When traffic travels by rail, society benefits.
... NetJets has long been an operational success, owning a 2010 market share five times that of its nearest competitor...My family and I have flown more than 5,000 hours on NetJets (that’s equal to being airborne 24 hours a day for seven months) and will fly thousands of hours more in the future...Whichever the plane or crew, we always know we are flying with the best-trained pilots in private aviation.
