When Icebergs Melt and Pieces Break Off, Sea Levels Rise?

[KenGordon]

This is why Scotland is going up and England is going down (aside from the Gammons) and luckily means there is a barrier in the Thames to keep the sea out.

Thames Barrier - Wikipedia

Sadly of course sea level rise is about four times the rate anticipated. This means Scotland is not going up fast enough and there will need to be a new barrier and extensive works down the Thames Estuary to keep London dry.

Melting icebergs (i.e. freshwater ice floating in the oceans) are not a relevant cause of sea level changes. If someone said so, it was in all probability a simple mistake. That happens to every one of use, even in topics we are well versed. For the observed sea level rise, added water (mostly meltwater from snow and ice that were above the sea level) and thermal expansion of the water itself are the two main contributors. The reason is human made climate change in both cases.

Again, they are not referring to icebergs that are already floating in the water.

Again, there are no other types of icebergs than those that float on the water.

When we freeze water in a glass, the freezing ice will expand, breaking the glass. Therefore, we know that liquid water has LESS volume after icebergs melt, which would have the reverse effect of shrinking the oceans, if all the ice was already in the ocean as icebergs. We fear the landed ice in glaciers.
Most tv presentations are not going to use words as technically accurate as the crowd here at Scubaboard prefers.

And where do those floating icebergs come from?

She likely meant "ice shelves" or something similar. Sometimes, people speaking live to an audience misspeak. And often, the audience lets it go with a simple "we're all human".

A shelf is ice that is also floating, but still connected to the land. Also a melting shelf does not rise the sea level. Most water influx is actually from far inland, e.g. glaciers, which would never produce ice bergs or shelves. If it was said they way it is reported here, it was a simple mistake. Not really a problem, and should not detract from the value of the talk!

Again, when a chunk of ice falls into the water, it is now an iceberg. Use some common sense man...

The living legend specifically mentioned ICEBERGS, which by definition, float in seawater.

Sigh....

Icebergs calve off of glaciers. Sea ice will not raise sea levels. But, any ice formed on land, as Bergs calving off glaciers are, will raise sea levels.

Just because they are now bobbing in the sea, they raised water levels the minute they fell off the glacier.

Sigh... The presenter said "Sea levels are rising drastically from pieces of ice that break off of icebergs".

She did NOT say "when ice breaks off of glaciers or other land based ice from which icebergs are originally derived".

Not sure why there are some posters on this thread who are having difficulty understanding this but I can't simplify it any more than I already have.
