Climate Change and Sea Ice Extent Quiz

What is the significance of the Arctic sea ice reaching its lowest maximum extent?

• It shows a stable climate trend.

• It indicates a cooling climate.

• It suggests a warming climate and less ice growth.

• It means more ice is forming than usual.

Since when have records of the Arctic sea ice maximum been kept?

• 1999

How does the Antarctic sea ice minimum contribute to global sea ice records?

• It has no impact on global records.

• It contributes to a global record high in sea ice extent.

• It stabilizes global sea ice extent.

• It contributes to a global record low in sea ice extent.

What do the changes in sea ice extent in both polar regions indicate about climate change?

• Climate change is occurring more slowly in polar regions.

• Climate change is not affecting polar regions.

• Climate change is occurring faster and earlier in polar regions.

• Climate change is reversing in polar regions.
