melting polar ice

Do we have some melting polar ice. Perhaps, there are rising seas.  There are many scientists who claim we face global warming. Frankly, I do not agree. Look at our ocean. It is not rising. I was in Miami this year. Water levels are the same, Docks are not underwater or near so. Believe me, nobody is building a sea wall to protect condos or complaining about flooding during high tide, so my answer is no.
