I've done the green hypocrisy idea before but this opportunity was too good to pass up. The Daily Mail (of England) had a long article with lots of images on Leonardo DiCaprio's speech, Sept 23, at the UN (first image) which warned of greenhouse warming as well as images of DiCaprio's houses (the image shows a house owned by DiCaprio in Palm Springs, California).
It turns out that DiCaprio has 4 houses (2 in California and 2 condos in NYC). He also is a frequent flier on private jets, rents mega yachts, etc.
The carbon footprint of Mr. DiCaprio is essentially off the charts. I would estimate it as two orders of magnitude above the average world per capita. The best thing here is that Mr. DiCaprio apparently thinks that because he sometimes drives a Prius hybrid and sometimes bicycles, he is 'not guilty' of carbon hogging (and of hypocrisy).
I think he is guilty of both.
