Article: Arctic's Old Ice Vanishing Rapidly, NASA Study Finds

The oldest and thickest Arctic ice seems to be vanishing faster than the younger, thinner ice at the edges of the Arctic Ocean's floating ice cap, a new NASA study finds.

Typically the thicker, older ice survives through the summer melt season (hence, it's called multi-year ice), while the younger ice that forms over the winter melts as quickly as it formed. That's what makes this new finding worrisome; if the ice that usually sticks around is rapidly disappearing, the Arctic sea ice is more vulnerable to further disappearance during the summer, said study researcher Joey Comiso, senior scientist at NASA Goddard Space Flight Center, Greenbelt, Md.

In the new study, Comiso and colleagues looked at multi-year ice that had made it through at least two summers. They wanted to see how it diminished with each passing winter over the past three decades. Results showed that the extent of multi-year ice, which includes areas of the Arctic Ocean where multi-year ice covers at least 15 percent of the water's surface, is shrinking at a rate of 15.1 percent per decade.

1. I think the death of Andrew Brietbart is far more important

than a little ice melting.

2. 'Cause we're only allowed to talk about one thing at a time?

3. i'm yoking

thinking of the grand scheme of things vs. what humans see as worth
getting agitated over.

Imagine if hundreds of thousands read this article and flooded social media
pushing for change regarding climate regulations?

I wish.

I saw this post right when I woke up, and I was like "Durrrr wut?"
