Greenland's Extreme Melt, 1 Year Later

The video discusses the early start of Greenland's melt season, which began a month earlier than usual. Brooke Medley from NASA's Operation Icebridge shares observations of increased liquid water on the ice sheet due to warm temperatures and low snowfall. The 2019 melt season was the second largest since 1980, raising concerns for 2020. Although 2020 is trending normally, the potential for significant melt remains. The meltwater contributes to global sea level rise, with Greenland being a major contributor outside of ocean thermal expansion.

What was unusual about the start of the melt season in Greenland?

• It coincided with a major snowfall event.

• It was the coldest start on record.

• It started a month later than usual.

• It began almost a month earlier than average.

What factors contributed to the extended melt season in Greenland?

• Higher humidity and more cloud cover

• Stronger winds and more icebergs

• Warmer temperatures and less snowfall

• Increased snowfall and colder temperatures

How did the 2019 melt season rank in terms of meltwater production since 1980?

• It was the largest on record.

• It was the second largest.

• It was the smallest on record.

• It was the third largest.

What is a potential consequence of an extreme melt year like 2019?

• It can result in more snowfall the following year.

• It can cause a reduction in sea levels.

• It can impact subsequent melt seasons.

• It can lead to a decrease in global temperatures.

What is the primary concern regarding the meltwater from Greenland?

• It will increase the number of polar bears.

• It will contribute to global sea level rise.

• It will lead to more frequent snowstorms.

• It will cause more icebergs to form.
