You're welcome. It's great when a journalist has a firm understanding of the subject, writes clearly and doesn't have an ax to grind. It's only been in the last decade or so that we've had the technology to measure changes in the earth's surface with this degree of accuracy.
The same is true with Antarctic ice shelves. These are the bands that hold glaciers in place. When the large ice shelves collapse sea levels will begin to rise more rapidly. Currently scientists are most concerned about the Thwaites glacier. The ice shelf that supports this glacier is likely to collapse by the end of the decade and hasten the release of this glacier that's the size of Florida.
