NASA | The Arctic and the Antarctic Respond in Opposite Ways

The video discusses the role of polar regions as Earth's air conditioner, highlighting their sensitivity to climate change. It examines the Arctic's significant ice loss and temperature rise, contrasting it with the unexpected increase in Antarctic sea ice. The video emphasizes the importance of understanding the relationship between Arctic and Antarctic changes to predict global climate impacts.

What role do polar regions play in Earth's climate system?

• They are unaffected by climate change.

• They act as air conditioners by reflecting solar energy.

• They are the primary source of global warming.

• They absorb solar energy and increase global temperatures.

Which region has seen a significant decrease in sea ice over the past decades?

• Both Arctic and Antarctic

• Neither Arctic nor Antarctic

• Arctic

• Antarctic

What is unusual about the recent Antarctic sea ice trends?

• The Antarctic sea ice is expanding beyond previous records.

• The Antarctic sea ice is melting faster than the Arctic.

• The Antarctic sea ice remains unchanged.

• The Antarctic sea ice is decreasing rapidly.

Why do some people incorrectly believe that global warming is not occurring?

• Because global temperatures are decreasing.

• Because the Antarctic ice increase offsets Arctic ice loss.

• Because the Antarctic ice is decreasing.

• Because the Arctic ice is increasing.

Why is it important to study both the Arctic and Antarctic regions?

• To confirm that both regions are warming at the same rate.

• To prove that ice loss is not significant.

• To predict changes in the rest of the globe.

• To understand the relationship between ice and global warming.
