NOAA Visualization: Disappearing “Old” Ice
December 28, 2015
I try to show this every time I give a presentation. Many people say it makes an impression, and I’m glad NOAA has updated to 2015.
Watch as the thickest, oldest, arctic sea ice (the lighter colors) disappears over the last 25 years or so – even tho the ice continues to freeze out every winter, the total mass/thickness continues to decline.
