Arctic Sea Ice Melting Over the Years | 2000-2022 Time-lapse

A time-lapse showing the change in arctic sea ice over time. Since the late 1900s, Arctic sea ice has thinned, and less sea ice has persisted in the Arctic over multiple melt seasons.

The pictures compared in the end are that of 1st January 2000 and 1st January 2022.

Since the late 1900s, Arctic sea ice has thinned, and less sea ice has persisted in the Arctic over multiple melt seasons. The trend toward younger, thinner sea ice over time reflects warming temperatures in the Arctic. As older ice is thicker than younger ice, the reduced area of old ice also indicates a reduction in the total volume of ice. Colors show the age of sea ice floating in the Arctic Ocean. The darkest blue areas on the map show seasonal or first-year ice, which formed during the most recent winter. White areas show where ice is more than four years old. Ice thickness is strongly correlated with ice age. First year ice ranges from 4 to 12 inches (10 to 30 centimeters) thick, while multiyear ice ranges from 6 to 12 feet (2 to 4 meters) thick. This correlation means that in general, the brighter the color, the thicker ice. (Arctic Sea Ice Age, Climate.gov)

In the mid-to-late 1900s, a core of thick, old year-round sea ice covered much of the Arctic Ocean. Around that core, seasonal ice formed each winter and melted each summer. North of Alaska, a looping current called the Beaufort Gyre historically acted as a nursery for young sea ice where ice could persist and thicken. Ice growth in the gyre roughly offset the steady transport of ice out of the Arctic Ocean through the Fram Strait east of Greenland. Since the year 2000, warmer summers have caused ice to melt in the southern stretch of the Beaufort Gyre, so less multiyear ice has persisted. The result is younger, thinner sea ice than in decades past. Today, the amount of thick, old ice in the Arctic is a small fraction of what it was in the 1980s. Because young, thin ice melts more easily than old, thick ice, the trend toward thinner ice is self-reinforcing. (Arctic Sea Ice Age, Climate.gov)

The biggest flaw with computer models is the "garbage in, garbage out" factor.

Gaaah. I remember when that 2000 coverage looked appallingly thin. The globe sitting on my desk in the late 70s had, you know, an ICE CAP on it, because until then the size of it wasn't changing all that much year to year! The whole polar circle was covered. I'm a GenXer, and the glacier I visited in Glacier National Park when I was a kid had retreated over a mile. There's thousands and thousands of before and after photos now showing the glaciers pulling back all around the world, but the accelerated pace in the past 20 years has really been an eye-opener... I didn't expect to see it happen so quickly in my lifetime.

We don’t have to worry about the ice that’s floating. What we really should worry about is the ice that’s on land. Ice that’s on land melting will flood the ocean, not floating ice.

[rickyyoungberry]

The ice caps are melting on Mars to, so obviously the ice caps melting on Earth has nothing to do with the Human race

[nevamindt]

Fascinating 🤔
Thank you for putting a visual to it 👍🏾

Earth Takes Care of Itself, Always Has Always Will.

[anthonymorris]

This has been going on for 10, 000 years. The entire northern hemisphere used to be covered in ice. Humans survived this without an ounce of technology. How is this a problem? Life flourishes under warming.

[roylangston]

So basically hit its low in 2012 and has not declined in 10 years.

[Dr.]

That's odd I just watched a 30 year time laps on Antarctica, and the ice has returned and then some.

[glenndavis]

There are fossilized trees north of the Arctic Circle in Canada.
Where no trees grow today.
So yes, it has naturally changed far more than it has today.

Were the 2000 and 2022 images at the end of the video of the same month of the year? Just wondering…

[francispalmer]

It's amazing how 22 years of Earths ice observation out of 4.5 billion years of Earths climate proves absolutely nothing.

[zvezda]

I don’t know what is on the map, but there is still a lot of ice off the coast of Russia. Russia only does what it creates nuclear icebreakers, makes documentary films about the Arctic and makes military ships with the functions of sailing breaking ice.

when the ICE is gone, where will cold air come from?

[spartan]

Some articles and another video I watched said that the arctic ice area had declined from about 6.5 million miles2 since 1979 [or 2000s?] to about 4.5 million miles2 by 2023. I believe that is minimum annual area roughly? It's not only the decline, but the rate of the decline that is shocking. Once the poles are gone, the rate of temperature increase globally will increase since there will be no more state changes from solid to liquid at the poles. My understanding is that the melting is slowing down the current annual increase in average global temps, but I might be wrong.

It is also true that the denial of global warming is almost only debated in North America, through mainstream and social media. It doesn't make sense for a global agenda of scientists to all uniformly falsify their data. I work at an institute that doesn't monitor this phenomenon, but when we have occassionally analysed our measurements in this regard, it agrees with steady increases in temperature over the last 30 or so years. Most of the false representation has actually come from the climate change deniers originating in NA, of which there are numerous stories of their falsifications caught on record, and them then changing their angles again, evidence of false motive, either political or financial.

If the natural cycle is cooling, which I haven't researched, then obviously the heating must be from people. It doesn't make sense to deny that changing the constitution of the atmosphere, through emissions in immense quantities, has no effect on the average temperature. Most of the temperatures on the other planets are due to the nature of the atmosphere, like venus, which is 475 deg C. Even though earth is not much farther, it is insanely cooler than Venus, and that is due to the constitution of atmosphere, not incident radiation.

Have periods similar to 2022 during the last 20 years scrolling thru the video plus periods like 2000 as well in later decades. Seems they think alot of heat waves is caused by less pollution since there is less particles reflecting the sun rays. Average planetary temp is the only thing that can prove the global warming as long as it does not look like this video as well. Ice melt does not do the trick. Read they measured the coldest ever temperatures in arctic a year ago. Anyway good that we are doing something to clean the air will improve our average life expectancy at polluted areas.

[trygvehadland]

It's just that thickness off the ice can't be measured from a satellite, it has to be flying over by a slow aeroplane or helicopter towing a sonar look a like sylinder in low altitude to measure the thickness of the ice, it's quite expensive and it almost never done in the dark winter period.
So this immiges is computer made with little information off accuracy.
There is also instruments that measured the ice floating between Greenland and Svalbard, but the analysis of the information has fall a year and a half behind because little money and tons of data.

[rudigereichler]

1979 was a peak year. Why do you start there and not say 1976 or when the northeast passage could be sailed with a 13m wooden sailboat.? Or 9000 years ago. We do not need sitellites to know.

[edimbukvarevic]

Seasonal minimum in September is flat for ~15 years. It will slowly start increasing this decade. There is a clear ~60 year cycle in most climate indices.
