NASA Releases Time-Lapse Of the Disappearing Arctic Polar Ice Cap

Arctic sea ice has not only been shrinking in surface area in recent years, it’s becoming younger and thinner as well. In this animation, where the ice cover almost looks gelatinous as it pulses through the seasons, cryospheric scientist Dr. Walt Meier of NASA Goddard Space Flight Center describes how the sea ice has undergone fundamental changes during the era of satellite measurements.

We don't have much time left. I'd rather spend as much time as possible on the internet arguing with strangers about politics.

[pullupboyzgta]

I notice how when 2000 hit the cap started melting faster

[shulupayaface]

Dam it. I just got toast crumbs in my bed. Oh bloody hell

[mrdrums]

Oh cool this'll help me sleep and not at all slip slowly into anxiety induced panic

[Lola-qwih]

nicely said I completely understood. Thank you

[manster]

i always felt like there used to be something bigger at the top of the earth, and know i know why i feel that way

[marcmy]

Stop saying it's fake, the description contains a link to to NASA's site where this is shown in more detail.

[rafaelr]

Just make a barrier between Greenland and Svalbard..

Even during the Holocene we have had much higher temperatures with less or no sea ice in summer when trees could grow much closer to the poles and much higher up the mountains. Earth's temperature depends on atmospheric pressure and not a trace gas like CO2 . CO2 is the gas of life of which we need more not less.

You want eagles the size of a stratofortress? Because this is how you get eagles the size of a stratofortress...

So glacial ice calf's off into sea/ocean, maybe resting on bottom maybe free floating, if the latter occurs then how does Archimedes' principle factor in or not regarding displacement and ocean levels?

There used to be classroom globes with a plastic cap on top. It was a bumpy surface, and about the diameter of a 33 1/3 rpm record label.
Do you remember these globes with the ice cap?
If yes, can you find one now? Let me answer for you. NO. Not even in an antique store. Not online, not when searching for vintage globes. Nowhere.

Winter in north : October, November, December, January, February, March, April, May
Summer : June, July, Aug September

[cradleofanal]

So that means we are getting better weather up in the north right?.. thank god.. summer are very short up here..

😖 poor artic animals and the animals who depend on the ice to live, especially it's gonna be a feed fest for the animals in the artic waters

Sea levels only rise if the amount of additional water from land based glaciers exceeds the amount reduced by evaporation. Although this varies it is part of a cycle. With increased temperature more evaporates and while it is trapped in clouds, raining, fallen on land or frozen as snow or ice on land it is NOT in the ocean. We have seen a collossal amount of flooding in recent years. While it will end up back in the oceans more will evaporate in this time. So the question is, is there more water being added to the oceans than is being removed by evaporation? If so, by how much?
Clearly we cannot just say that the water level will rise by such an amount in such a time purely by measuring glacial melt. Ideally to measure sea level increase we need to measure it directly. Obviously this is impossible with any accuracy. Sea level rise and falls on a second by second basis. We can not compare the level at a particular place with the level at that same place and time but a year later. We cannot even establish the same PLACE thanks to coastal erosion, beach build up, and continental drift. Even if we could, weather, tide, wind, waves, the moon etc. would all need to be the same, or accurately accounted for. Also, our ability to measure accurately has increased considerably over the last half century rendering accurate comparisons to within millimeters, inches or even feet suspect.
If we are going to have to rely on indirect measurements like glacial melt we have more than evaporation to take into account. Coastline changes, volcanoes, volcanic dust, seabed changes, earthquakes, the position of the moon and possibly sun spots may affect sea level.
Also, for every millimeter increase the volume of water to fill the next millimeter is much larger as most coastlines SLOPE.
So is sea level rising? Possibly, possibly not. What is certain is that the Climate has changed and appears to be changing at an ever increasing pace.
I think sea level rise is the least of our worries. Increasing numbers and larger hurricanes, tornadoes, thunder storms, fires, floods, snowfall, sun created cancers and virus pandemics seem of much greater concern.

Why don't you continue to show the views since 2016? And why aren't you mentioning influences such as sun activity? What a cliff hanger ...

Ice melting in Greenland contributes more than a millimeter rise to sea level every year, and that's likely to get worse. Sea levels are projected to rise by more than 3 feet by the end of the century, wiping away beaches and coastal properties.
Coastal states like Florida, and low-lying island nations are particularly vulnerable. Just 3 feet of sea level rise could put large areas of coastline underwater. Forty percent of the US population resides in coastal areas that are vulnerable to sea level rise

[tomstanley]

if i was to see all the time laps of this you have would be better than just five years ?

[johnthebaptist]

Ice on water is ok. Ice on land on water…
