NASA | Earth's Climate Checkup: Operation IceBridge Monitors Arctic

The video discusses NASA's Operation Icebridge, highlighting the importance of the poles in regulating Earth's climate and sea levels. It explains the complementary roles of planes and satellites in studying ice, emphasizing the use of radar and LIDAR for detailed analysis. The current state of Arctic ice is addressed, noting significant melting and its implications. The importance of glaciers, particularly in Greenland, is discussed in relation to sea level rise. New initiatives in the Icebridge campaign, including expanded research in Canada and enhanced altimetry measurements, are introduced. The video concludes with insights into the experience of conducting Arctic research campaigns.

Why are the polar regions crucial for Earth's climate?

• They are the only source of fresh water.

• They have no impact on global temperatures.

• They are isolated from the rest of the planet.

• They influence the climate and sea levels worldwide.

What is the primary advantage of using planes over satellites in studying polar ice?

• Planes can fly longer distances.

• Planes can map the ice bed and measure thickness.

• Planes can cover the entire planet.

• Planes are cheaper to operate.

How has the size of Arctic ice changed over the years?

• It has melted back to less than half its original size.

• It has doubled in size.

• It has grown larger.

• It has remained the same.

Why is it important to study glaciers in the context of sea level rise?

• They have no effect on sea levels.

• They are a major contributor to sea level rise when they melt.

• They are located far from the ocean.

• They are not affected by climate change.

What new initiative is being undertaken in the Icebridge campaign this year?

• Stopping all research activities.

• Reducing the number of flights.

• Sending a second aircraft for detailed measurements.

• Focusing only on the Arctic sea ice.
