NASA | Arctic Sea Ice Sets New Record Winter Low

The video discusses the Arctic sea ice reaching its peak extent on February 25th, marking the smallest winter maximum since 1979 and the second earliest peak. It highlights that much of the winter ice is thin and will melt in summer, with scientists noting that summer minimum trends are more indicative of climate change. A visual comparison shows the current ice extent against the average from the past 35 years, particularly near Russia and Alaska.

When did the Arctic sea ice reach its peak extent for this year?

• March 1st

• April 10th

• February 25th

• January 15th

Since when have we been consistently tracking the Arctic ice pack with satellites?

• 2000

• 1979

• 1990

• 1985

Why do scientists find trends in the summer minimum extent more interesting?

• They are a better indicator of climate change

• They cover a larger area

• They are easier to measure

• They occur more frequently

What does the yellow color indicate in the video?

• High ice extent near the North Pole

• Low ice extent near Russia and Alaska

• Regions with high temperatures

• Areas with thick ice

What is compared to this year's ice pack in the video?

• The ice pack from 50 years ago

• The ice pack from the last decade

• The average maximum coverage from the last 35 years

• The ice pack from last year
