Is global warming real?

If Global warming is real why do many many many people who say it is real own beach front property? This includes Obama and Suzanne Streisand. I also think if the world is going to die if I used too much energy I would stop flying on planes. Millions of selfish people fly on planes all the time, every year. It has been 6 years since I flew on a plane. Judge yourself first not others wouldnt that help the world? Yes, I think it would.
