Animations Show the Melting Arctic Sea Ice, and What the Earth Would Look Like When All of the Ice Melts

It's no secret that climate change has been taking a toll on the Arctic. But it's one thing to read about it, another thing to see it in action. Above you can watch an animation narrated by NASA's cryospheric scientist Dr. Walt Meier. Documenting changes between 1984 and 2016, the animation lets you see the Arctic sea ice shrinking. As the important perennial sea ice diminishes, the remaining ice cover "almost looks gelatinous as it pulses through the seasons." For anyone interested, an updated version of this visualization can be downloaded in HD here.

If you're curious what this could all lead to--well, you can also watch a harrowing video that models what would happen when all the ice melts and the seas rise some 216 feet. It isn't pretty. The video below is based on the 2013 National Geographic story, "What the World Would Look Like if All the Ice Melted." http://www.nationalgeographic.com/magazine/2013/09/rising-seas-ice-melt-new-shoreline-maps/

1. Both are worth watching. -nt

2. we're screwn...

Literally...

You know what nobody talks about is that ALL the "models" have been blown out of the water in the last 10 years...Stuff they were telling us that wasn't gonna happen for 50-100 years is happening already. So ya, basically...it's not 2100 we gotta worry about, it's 2035-2040...

My 18 yr old daughter is now saying stuff like "we're all gonna die in 20 years, so fuckit"


It's terrifying AND heartbreaking. the Earth will recover long after she's been cleansed of US....I hope

4. Al Gore warned the world. He tried to give us some time. Some of us believed him. Few of us acted.

5. florida completely gone. trumps sharpie would zap out lots of Alabama also.

7. Mobile floods in normal rain.

The older part of the city. Some areas have a bit of elevation, which is nice when our monsoons come to visit.
A cat 4-5.....all bets are off.

6. Kicked and recommended.

Thanks for the thread littlemissmartypants.

8. This is probably a stupid question but

if frozen ice that melts doesn't add anything to the sea level, will the sea level rise from the warmer oceans that are absorbing the heat as opposed to white ice which reflects the heat of the sun?

11. 2 things raise the sea level: ice that is currently on land, and the warmer oceans

While floating ice doesn't raise sea level, if the ice caps in Greenland and Antarctica melt, they run into the oceans. Yes, warmer oceans expand, so the level rises. The two effects are fairly close, it's thought.

Thermosteric sea-level rise was estimated to account for approximately one-quarter of the observed rate of global sea-level rise from 1961 to 2003, contributing 0.32 ± 0.12 mm yr-1 down to 700 m depth and 0.42 ± 0.12 mm yr-1 down to 3000 m depth. For the last 10 years of that period (1993–2003), the contribution of thermal expansion was estimated to have increased to 1.5 ± 0.5 mm yr-1 above 700 m and 1.6 ± 0.5 mm yr-1 above 3,000 m, about half of the observed rate of global sea-level rise.
...
The IPCC Fourth Assessment Report estimated that losses from glaciers and ice caps contributed 0.58 ± 0.18 mm yr-1 to sea-level rise from 1961 to 2003 and 0.77 ± 0.22 mm yr-1 from 1993 to 2003 (Bindoff et al., 2007), with the most rapid ice losses occurring in Patagonia, Alaska, northwest United States, and southwest Canada (Lemke et al., 2007).

12. OK, I think I get it now. Thanks!

9. That second one is scary!

I hope it's an eye opener
