A one trillion tonne iceberg – one of the biggest ever recorded - has calved away from the Larsen C Ice Shelf in Antarctica. The calving occurred sometime between Monday 10th July and Wednesday 12th July 2017, when a 5,800 square km section of Larsen C finally broke away. The iceberg, which is likely to be named A68, weighs more than a trillion tonnes. Its volume is twice that of Lake Erie, one of the Great Lakes.

Why would this "magically disappear"? It's not related to global warming, it happens all the time, it won't raise sea level one iota. The only reason to suppress this story is a concern that stupid people on the Internet would mis-report it - oh, wait a minute, there are millions of stupid people on the Internet, that might happen after all.

A small correction. It cannot be shown to be directly connected to global warming. This is not at all the same as saying it is not connected to global warming. There are clear indirect connections. True, they probably only affect the speed at which this kind of thing happens, but the speed is not unrelated to the size of the resultant berg, and it also affects the rate at which the glaciers are moving from the land onto the ocean (i.e., becoming ice shelves).

I have no idea where people are getting this idea that climate change cannot be linked to any evidence. That doesn't even make sense. Here is a description of two of the people studying this discussing the evidence about a link to global warming:

Actually, it will [phys.org], just not very much.

"But while the birth of the huge iceberg might look dramatic, experts say it will not itself result in sea level rises. “It’s like your ice cube in your gin and tonic – it is already floating and if it melts it doesn’t change the volume of water in the glass by very much at all,” said Hogg."

You have to wonder on whose payroll these "experts" are.
The post by WalksOnDirt mentions the difference in fresh water vs salt watter.
Yeah, that's a factor.
A bigger factor is that this ice hasn't always been floating.
It was part of the continental mass and -now- is floating.
True, an ice cube that is -already- in your drink won't raise the level of the fluid as it melts.
An ice cube that you take out of the bucket and drop into your drink WILL raise the level of the fluid.
This isn't even junior high Science.
Kids figure this out the first time they make their own iced drink.
Why you (and the "experts") don't grasp the concept remains a significant question.

It is an ice shelf, by definition it is floating:

When was it last not floating? My understanding is that while the ice of the shelf is relatively young (according to Wikipedia [wikipedia.org], about two centuries maximum age), the ice shelf itself has been floating for much longer than a couple of centuries and hence, has been around since before the industrial age.

A fresh ice cube melting in fresh water won't. It will, slightly, if the water is salty.

Which is in accord with what I said. There is only a slight change in volume from melting floating fresh ice into sea water, but it is definitely not none. Actually look at the link I posted, instead of ignoring it.
