NASA | OIB Flights South 2014: A Sea Ice Mystery

The video explores the mystery of expanding Antarctic sea ice despite global warming. While global temperatures rise and ice melts in the Arctic, Antarctic sea ice is increasing. Scientists attribute this to stronger winds from the Antarctic continent, possibly due to the ozone hole. Additionally, increased precipitation and freshwater contribute to sea ice growth. However, the overall global sea ice is decreasing, with Arctic losses outweighing Antarctic gains. The video highlights the need for scientific observations to understand these phenomena.

What is the main mystery discussed in the video regarding Antarctic sea ice?

• Why it is the same as Arctic sea ice

• Why it is unaffected by climate change

• Why it is expanding despite global warming

• Why it is melting faster than expected

What is one of the suspected causes for the increase in Antarctic sea ice?

• Decreased global temperatures

• Increased volcanic activity

• Stronger winds from the Antarctic continent

• Less sunlight reaching the poles

How might the ozone hole influence Antarctic sea ice expansion?

• By increasing ocean temperatures

• By reducing snowfall

• By increasing sunlight exposure

• By strengthening winds from the continent

How does increased precipitation contribute to sea ice formation?

• By decreasing air temperature

• By increasing ocean salinity

• By reducing ocean salinity

• By increasing sunlight exposure

How does the change in Antarctic sea ice compare to the Arctic?

• Antarctic sea ice is decreasing faster

• Both are increasing at the same rate

• Arctic sea ice is increasing faster

• Arctic sea ice is decreasing three times faster
