Arctic Changes
These videos, graphics and animations digest information from countless satellite and submarine measurements, developing a picture of change in the Arctic as it has warmed. See the miles-high view — and what’s happening from underneath, too.

- Envisioning Ice Loss
- Greenland lost an average of 577 billion tons of ice per year from 2004-2007. But just how much is that?

- Alaska’s Ice Drain 2004-07
- Alaska has been shedding large amounts of ice into the sea – on average, enough to fill a daily freight train around the world.
-
Graphic
- Alaska Total Ice Loss 2004-07
- Alaska has been losing tremendous volumes of ice to the sea.
-
Graphic
- Greenland Total Ice Loss 2004-07
- Greenland has been losing large amounts of ice into the sea – enough to collect into rafts the size of states.

Graphic
- Greenland and San Francisco Bay
- Greenland has been shedding billions of tons of ice – in 2007, the melted equivalent of draining San Francisco Bay every 10 days.

- All the Ice on Greenland
- Greenland holds enough ice to raise global sea level 23 feet – or to fill the Lower 48 states 2,940 feet high, like a bathtub.

- Accelerated Ice Loss from Greenland
- Greenland lost much more ice in the 2000’s than the decade before.

- Greenland Annual Ice Loss 2004-07
- Greenland’s estimated ice loss each year from 2004 through 2007.

- Arctic Sea Ice Thinning: Fall
- Fall view: Arctic sea ice has been getting thinner – even faster than its area has been shrinking.

- Arctic Sea Ice by the Decade
- NASA satellites have watched Arctic sea ice for three decades now, and the record shows more and more melting over time.

- Arctic Sea Ice: Heat Shield
- Arctic sea ice acts like a heat shield, reflecting most of the sun’s energy. As the ice has melted back, it reflects less, and the planet is absorbing more heat.
