"If anyone is basing their conclusions on faith it's you."
Not at all.
"faith" can be defined as:
"2. Belief that does not rest on logical proof or material evidence. "

Proving that AGW is causing sea level rise is a proof by exhaustion, though the rise is unquestionably caused by changes in ocean temperature and glacial ice mass. In the absence of other plausible causes, I think AGW as a cause a logical assumption. If a plausible alternative is found, or sea levels trend lower, my opinion will change.
Again, I would ask you for some parameter about which your opinion could change. Unless you provide this I can only conclude that your opinion is faith based.
