NASA | Arctic Sea Ice Reaches 2014 Minimum Extent

The video discusses the decline of Arctic sea ice, which reached its sixth lowest extent in 2014. Arctic sea ice acts as a natural air conditioner by reflecting sunlight, thus cooling the planet. Since 1979, satellite monitoring has shown a significant loss of sea ice, equivalent to about a third of the United States. The Arctic has warmed two to three times faster than the global average, contributing to the decrease in sea ice thickness and extent. Thinner ice melts more quickly, making it less resilient. The loss of Arctic sea ice is a significant indicator of climate change, impacting global climate systems.
