I think the rise over the past sixty years is about ten centimetres hanrahan so it's pretty insignificant and not obvious. Also due to a variety of factors the rise is not uniform all over the world, but I accept there has been a small rise.
I don't think that humans are the cause but there is no proof either way about that.
As I mentioned previously Pacific Atolls have a history of slowly sinking back into the sea from which they rose and the climate change brigade are being dishonest using them as an example of rising sea levels.
