World’s largest iceberg breaks off frozen edge of Antarctica

The video discusses an iceberg calving from the Ronne ice shelf in Antarctica, highlighting its size and comparisons to Mallorca and New York City. It explains that the iceberg's melting won't raise sea levels as it was part of a floating ice shelf. The video also addresses climate change, noting that this iceberg's formation isn't linked to it, but warns of significant sea level rise if Antarctica's ice sheet melts.
