Antarctic Sea Ice Hits Record Low in 2023 : Climate Concerns



  Sep 27, 2023

Antarctic Sea Ice Hits Record Low



Q: What is the current status of Antarctic sea ice?

A: According to U.S. National Snow and Ice Data Center (NSIDC), Antarctic sea ice reached a record low surface
area of 16.96 million square kilometers on September 10, 2023, at its winter maximum.

Q: How significant is this low?

A: This is the lowest sea ice maximum in the recorded history from 1979 to 2023.
It is 1.03 million square kilometers smaller than the previous record.

Q: What is the winter maximum?

A: Sea ice in Antarctica typically expands to its largest size during the colder winter months.
The September 10 reading will likely remain the maximum size for this year.

Q: What about Arctic sea ice?

A: Arctic sea ice also shrank to a low of 4.23 million square kilometers, the sixth lowest minimum in 45 years of record-keeping.

Q: Has Antarctic sea ice been stable before this?

A: Antarctic sea ice had remained relatively stable, even expanding slightly, for several decades prior to this record low.

Q: Why is this significant?

A: Shrinking sea ice can have far-reaching impacts on global climate patterns, ocean currents, and marine ecosystems.
It is an indicator of climate change.

Q: Who reported these findings?

A: The findings were reported by the NSIDC, a government-supported program at the University of Colorado at Boulder.

Q: What are scientists saying about it?

A: NSIDC scientist Walt Meier described it as a "record-smashing sea ice low in the Antarctic."

Q: Are similar trends observed elsewhere?

A: The Arctic sea ice also shows a trend of shrinking sizes, although it hasn't hit a record low this year.

Q: What actions are being taken to address this?

A: While the report does not specify actions, global initiatives aimed at reducing climate change may indirectly address sea ice loss
