The Decline of Arctic Sea Ice: A Look at the Data

What has happened to Arctic Sea Ice since 1980?

a. not changed in volume or surface area b. not changed in volume, but decreased in surface area c. decreased in volume and surface area d. decreased in volume, but increased in surface area e. decreased in volume but not changed in surface area.

Answer:

c. decreased in volume and surface area

Since 1980, Arctic Sea Ice has experienced a significant decline in both volume and surface area. Data from the National Snow and Ice Data Center shows that the extent of Arctic sea ice has been decreasing notably during the 1980s and 1990s.

This decline in Arctic sea ice is a cause for concern as it has implications for global climate change and the delicate ecosystem of the Arctic region. The melting of sea ice can lead to rising sea levels, altered ocean currents, and impacts on wildlife that rely on the ice for survival.

Scientists continue to monitor Arctic sea ice levels closely and study the reasons behind this decline. Understanding the changes in sea ice is crucial for assessing the effects of climate change and taking action to protect the Arctic environment.
