Today’s Video of the Day from NASA Goddard reveals that Arctic sea ice is now the thinnest that it has been in at least six decades.
Scientists at NASA used satellite and submarine sonar data to reconstruct the thickness of the ice over the past 60 years.
The study revealed that more than 70 percent of the ice is now seasonal, expanding in the winter yet melting in the summer.
According to NASA, the thin, seasonal ice is much more susceptible to climate conditions.
