Are Claire and Jack siblings? I think so, but I'm not entirely sure. Can someone clarify?

I just finished season 2 and man, it's just amazing. Every episode is so exciting, I'm always wondering what's going to happen next, and I'm watching 5 episodes in one day. I would love to watch it when it comes out because I want to experience the excitement of waiting for the next season.
