NASA | Sea Ice 2008

The video discusses the alarming decline of Arctic sea ice over the past three decades, highlighting the record-breaking melt in 2007. It explains how increased open water leads to more solar energy absorption, further warming the Arctic Ocean. The potential loss of perennial ice could result in a blue ocean, causing significant environmental and ecological impacts. The video also contrasts the Arctic situation with the Antarctic, where sea ice has not declined due to different climatic factors. NASA's research using satellites aims to understand these complex phenomena.

What are the potential ecological impacts of losing perennial ice in the Arctic?

How do weather patterns like La Nina and El Nino influence sea ice trends?
