Oh thank the Lord somebody thought of doing this. The arctic needs our prayers SO MUCH and yall are praying for some football game? God has better things to worry about and he (or she) needs to hear about this. (Everyone has this person on their Facebook, I swear)
Thank goodness for that. In school everyone was worried about the sea levels rising to the point of mega natural disaster... But what this is trying to show is that (1) this is all cyclical, and has been happening forever (2) Ice melting, that was already sat in the water, doesn't raise the level of the water as it melts... That's a relief!!!
And deep sea water is dark, so absorbs heat, snow and ice don't, they reflect it. so with the ice melting, exposing darker sea water, it's just compounding the situation. That's how you get a runaway greenhouse effect. One thing impacts another which impacts another and so on. The ice lakes in Siberia also hold loads of methane, once they melt things are gonna get much worse. They recon they hold millions of tons of methane under those lakes!
@@trunzlerclement3227 The change in temperature precedes the change in carbon level by up to a year. 97% of all carbon emissions are natural. Every. Single. Prediction. that has been made regarding the climate from these scientists has been wrong. Remember the hole in the O-zone thing?. Yes, the planet is changing. It has for millennia. Don't be so arrogant to think that humanity has any control over Earth's temperature. Carbon levels rise as the planet gets hotter, as more organic matter decomposes. I don't deny the planet's climate changes. I just have working long-term memory. Incidentally, the year this was made was also the year Al Gore said we'd already be flooded. Let's not give these people any more power. They're wrong.
Or what about the ongoing surface mining (40-400m deep) all over the world that leaves only deserts and canyons and destroys farming grounds (food production)?
There is no such thing as deforestation. That's an alarmist myth to scare people. For every tree cut down it gives a signal to the market to plant a new tree. We should use more wood instead of less. CO2 is plant food, you know.
I knew this was happening due to James Hansen's work almost 30 years ago and we did absolutely nothing for decades. We would be so much farther ahead by now but climate change became a partisan issue in the 90s and then action stalled.
Steve J, Sorry, but that is old information, and thus somewhat inaccurate. In 2015 Antarctica had, at it's winter maximum, the greatest sea ice area that has been seen since accurate satellite recording started. Note that this was a thin seasonal sheet of large area but but comparatively little volume. In the couple of years since, Antarctic ice (both winter max and summer min) have undergone a drastic decline in both area and volume. This years summer ice minimum was the lowest sea-ice area that has been seen in Antarctica since satellite records begun. nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/
Gaining snow ice in the middle of the continent, but losing it along the edges, where it buttresses land ice glaciers, which are moving, faster in the last decade.
@loblocks222: the problem: mass of water displaced by floating ice is equal to the mass of the ice; melting the floating ice doesn't change the ocean level, or at least does so minimally. OTOH ice resting over land melts, water flows into the ocean and raises the sea level. So the harm coming from melting Antarctica is much worse than melting northern Arctic.
I love how many scientists there are in this comments section. I see so many experts educating other experts. Amazing how many smart people are in the UA-cam comment section, astounding really.
The reason why there are such crazy denialists in this debate is that they know that without industry heavily regulated our civilisation can't survive. The other crazy thing is that retooling the human race with new energy sources is exactly what the world economy needs. Just the the rebuild after WW2 created the great economy of the mid 20th century a "green new deal" could do the same for the 21st century. Just bloody hard to get things done in a plutocracy and some little people hanging onto weird ideas.
Well that, and scientists have been wrong about every prediction they've made about this. Gore said we'd see mass flooding by 2016. Maybe these guys aren't very reliable.
We all are ok and will continue to be. Did you know that the CO2 levels over the past 500 million years averaged about 2-5x what it is now? It's extremely low currently. Life thrived back then. There isn't even enough CO2 in the air for plants to grow anywhere near optimally. Which is why CO2 is pumped into greenhouses. A warmer earth is definitely a good idea.
He said the data they are showing is false and misleading. No one denies global warming, it has been going on since the coldest day of the ice ages. And it is accelerating every day after.
This is about the decline in sea ice not land glaciers. And these images are created from the microwave satellite data and thus not photographic images.
You're probably more likely to accidentally kill something from temperature shock or hard impact from waves crashing the ice onto organisms. Which is hilariously ironic.

The graphic actually starts over at about 1:15 going back to the beginning when the ice decline in the Arctic was observed based on satellite data. Watch it several times to see the sharp declines in summer 2007 and 2012 and then toward the end sea ice muli-year ice drops even lower. Another UA-cam video shows the sea ice decline right up to July 2019.
In other words sea ice melt does not add to sea level rise just like melting ice cubes in a glass of water do not raise the water level when they melt.
In minute 1:05 its still labled as sea ice age. The old ice is almost gone in that moment just like in the sep 2016 snapshot. Wouldnt this be considered a natural?
Well, yeah, that is clear as day if you just look at the video and see that no ice is really melting, there was a single bad year that took the old ice but new ice took its place. This graph is deceiving as all hell.
The problem with geo-engineering is that you cannot predict all possible side effects. What if your barrier disrupts water flow and makes something else accelerate?
The climate scientists, though they may find it disturbing, have more in common with those who stop in dread and fear to pray (out of respect and forced humility for what they don't understand) than those who are unwilling to stop treading the current path (aka the majority of society). Divide and conquer.
They are just showing the start of their data gathering vs the last record. Clearly it's melting, but what the cause of it is still up for debate. Many argue that this melting is caused by humans. Some argue it's simply normal for the EArth's atmosphere to fluctuate. We really don't know. We do a lot of speculation on both sides of the argument. I'm on the fence, it could be a combination of things outside our knowledge. I think we should do our best to reduce creating greenhouse gases but let's not kill each other over it. I personally believe these things sort themselves out. Whether it be war or famine but something's gotta give sooner or later.
Dear Dr. Walt Meier of NASA Goddard Space Flight Center. Please allow an answer for my following question. The years of this timelapse film are from 1986 to 2016? Is that right? More importantly, at some point the mature ice takes a sudden decline and never recovers, can you provide a specific time for when that stark drop off appears to have occurred and what events may have been going on globally leading up to and during the time of this dramatic sea ice loss? P.S. I can look provide the time stamp as referance if you cannot deduce what point in film im referring to but I very well believe you capable! Forgive me if I remembered the beginning and end years incorrectly. Thank you for your dedication and passion.
@SaRa. This particular graphic starts in 1991 and runs to 2016 and starts again at the same time at 1:16 showing the year in the left hand corner instead of the color code reflecting the muti year sea ice.
Take plastic from the Great Pacific Garbage Patch and create artificial ice bergs to reflect light from the arctic circle and it will cool down and form more ice. Could make floating plastic dens built into the plastic ice bergs for the polar bears to use as well.
It's like watching the planet trying to breath. But every breath becomes thinner and thinner, and brings less oxygen to the lunges than the previous. Literally watching the death of a planet.
That something is hard is not a reason not to do it. IceBridge has been using lasers to measure thickness for years, and IceSat2 will do it globally from space. Lasers!
Yueh Tewb Yueh knoe according to climate science that started all this was about 25 years before that. We should be all done frozen over by now, but noooo! Wayyy too many keyboard climatologists in the "Tewb" anymore...good luck all see ya all on the bright side.
@@jasonmartin4775 you do know its a computer simulation right sport. All data man made and input into the computer to output what they want you to see.
This is no joking matter. The consequences of inaction will likely be shortages, then hunger, and finally starvation in the industrial countries at some point. Planning now might reduce that likelihood. Contact your representative and let them know you are a single issue voter.
This is a great animation, thank you guys. I think it's important to mention the "during the era of satellite measurements" - I mean, how can we make sure this relates to human activity ? Also, from what I've read on the Nsidc, isn't the Antarctic ice at the south pole increasing ? Not questioning the climate "change", just questioning our responsability in all this, thanks.
barrettdesigns thats actually not true, the antarctic is growing slightly (due to the ice melting and making the water less salty, therefore making it easier to turn into ice) ,but it is not growing fast enough to outgrow the arctic melting, and soon that thin ice around antarctica will melt too...
Thecl Artic is perfectly healthy and record this winter too. It's all natural cycles. We're likely entering a cosmic ray indused little ice age, brought on by incoming weak the sun cycles.
That's not accurate. f you wish to compare, Antarctic ice (land and sea) has been growing by about 82 gigatonnes per year for the last few years. Greenland alone has lost an average of 238 gigatonnes in that time range. www.nasa.gov/content/goddard/nasa-study-shows-global-sea-ice-diminishing-despite-antarctic-gains Antarctica gained 82 gigatonnes of sea ice per year from 2003 to 2008. Greenland alone has lost an average of 238 gigatonnes per year from 2002- 2015, and that's land-based ice cap, which contributes to sea level rise. www.nasa.gov/content/goddard/nasa-study-shows-global-sea-ice-diminishing-despite-antarctic-gains www.arctic.noaa.gov/repor.../greenland_ice_sheet.html More recently, however: www.nasa.gov/feature/goddard/2017/sea-ice-extent-sinks-to-record-lows-at-both-poles
Based on your own numbers the 82 gigatonnes of sea and land ice per year. Your comparison dataset is 2002-2015 which is 13 years. 82 gigatonnes times 13 years equates to 1,066 gigatonnes which is vastly more than the 238 you mention. Your second comment references 238 per year so youre either misrepresenting your data or intentionally being confusing to swindle the public. Personally, I'm pleased to see the NASA mission reset back to its core. I'm tired of tax money being wasted to swindle the public on fake environmental concerns.
David Bolger Taking millions of pictures of the North Pole from literally the same exact place for 32 years for no reason because clouds will cover everything anyway doesn't seem like a great plan to me.
Yeah, Europe will get colder, but more equatorial regions will become inhabitable sending waves and waves of "climate refugees" to colder regions. Coastal areas will also flood causing people to move inwards. All this movement will cause demographic catastrophe. There will be wars for resources like water or food. All in all this is terrible news for everyone.
we don’t know exactly. To my knowledge the best current estimate of what will happen is Hansen 2016: www.atmos-chem-phys.net/16/3761/2016/ It also lists the uncertainties which still need to be addressed to get a stronger estimate.
The sea level has in fact risen enough to engulf some inhabited islands already. This received little media attention but there are people permanently homeless due to changes that never happened in all prior known history.
Amazing video, theres no thick ice left. Same probably has happened to forests and animals living in forest. Beside these we get new land made of plastic in the oceans. We might be doing something wrong?
I thought Ireland was under ice during the ice age? Or does this model ignore northern Europe? Also, the amount of thick ice at 1:03 looks a lot less than in 1993. What is this model based on?
Mourning Ireland NASA's Polar orbiting satellites took images of the ice extent and thickness over the last couple of decades, these satellite images were used to make the animation you saw.
What the Arctic is doing is cycling DOWN to the point when there is no Arctic sea ice in the summer which will lead to greater warming for the rest of the planet. That will come sooner then you think. And as the Arctic warms still further we will see the release of methane in massive quantities which will accelerate warming!! COMPRENDE???
It is not as dramatic as this video because most sea ice melts back around Antarctica every year. The bigger concern with Antarctica is the accelerating melt rate of land glaciers in western Antarctica.
You have to remember that what we are seeing is a computer animation that is sped up. Not a time lapse. That might not seem important but it is. A time lapse is when a camera 'captures' and records an event. This is an animation that was preprogrammed to do one thing. Most of you know that a camera was not actually perfectly affixed above the earth in the same spot for 30 years, but face it; you know plenty of people will think so. And their vote is just as powerful as yours. You have to be reliant that the data that was plugged into the animation and trust that it's accurate. One of the problems I see is that although we have had flooding in some areas, it has not been unprecedented. We have been told again and again to anticipate massive population displacement but the amount of arctic ice simulated to have melted has not resulted in the flooding we should have expected from it. Then there is the famous photo that Al Gore carts around which shows an ice shelf grown to the shore from atop a mountain 40 years ago, and he then shows a newer photo of the same area that shows how much the ice has retreated. Then every year, someone goes back in the winter and snaps a new photo of the ice returned, only to have an alarmist go back in the summer and show it had retreated again. And on in on it goes. Global Warming continues to run into scientific problems when what people should be most concerned with is actually the depletion of natural resources. Natural resources that are either becoming scarce due to deforestation, urban expansion, relentless mining, over fishing, poisoned waters, poisoned air, etc. While we have this major push for climate change we have virtually NO push to change that we have killed off 70% of earths wildlife since 1950. State-run medias take turns highlighting each other's war crimes but no anti-war movement will make the news. Customers find themselves bled dry as they are forced into new energy markets, all pushed by 'clean energy'. But no one will talk about a clean planet that is dying more and more each day. The UN recently passed legislation which requires vessels visiting Antarctica to first register in order to "preserve" the continent. Thus far, very few private institutions have been able to gather private research. Only government agencies have been permitted to enter.
What satellite is the sea ice data from? The “Daily image update,” as well as many of the images shown in Arctic Sea Ice News & Analysis, are derived from the Sea Ice Index data product. The Sea Ice Index relies on NASA-developed methods to estimate sea ice conditions using passive-microwave data from the Defense Meteorological Satellite Program (DMSP) the Special Sensor Microwave Imager/Sounder (SSMIS). The basis for the Sea Ice Index is the data set, “Near-Real-Time DMSP SSM/I Daily Polar Gridded Sea Ice Concentrations,” and the NASA-produced “Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Passive Microwave Data.” For more details, see the Sea Ice Index. Why is the Sea Ice Index product used to study sea ice? The passive-microwave data used for the Sea Ice Index is especially helpful because the sensor can “see” through clouds and deliver data even during the six months of Arctic darkness and frequently cloudy conditions. Some other satellite sensors cannot penetrate clouds to take data, so the results are sporadic and dependent upon weather conditions. Still other sensors can see through clouds, but they do not cover the entire region of the globe where sea ice exists every day, making near-real-time monitoring difficult. Furthermore, some sensors cannot provide information in winter, when polar darkness prevails. The passive microwave sea ice record dates back to 1979, one of the longest environmental data sets we know of. This provides a long-term product that consistently tracks changes in the ice cover over many years, lending additional confidence to the trends that we observe. So, although NSIDC refers to additional satellite data in developing our analysis, we primarily rely on passive-microwave data for Arctic Sea Ice News & Analysis images and content, and for tracking long-term change. nsidc.org/arcticseaicenews/faq/
Uneducated people often dwell on nonsense or absurd suggestions to avoid facing reality when it is their own lack of understanding that is the problem!!
I, for one, welcome the day when we have an ice-free Arctic. Will be a major boon for economic progress and will shorten trade routes. We still have a LONG way to go until we reach the conditions of the last interglacial. The ice age of Greenland being the dead giveaway in that regard.
The current warming of climate and related Arctic ice retreat is occuring much faster then occured in the past interglacial periods. When the Arctic becomes ice free in summer then the albedo of the Arctic will be near zero and almost all sunlight will be absorbed by the Ocean warming and in turn warming the rest of the planet still further. And with GHG's contiinuing to rise in the warming the climate will continue to warm from that cause. As the Arctic sea ice withdraws from the Arctic this allows the waters to warm and allowing for the potential and rapid increase in methane release from the permafrost. Peter Wadhams who has studied the Arctic for almost 50 years reports that the release of this methane could come as a dramatic spike in methane levels, a methane bomb as it were which could raise global temperatures by 0.6 °C in a short time. This is what years of research on the changes going on in the Arctic has indicated is a real concern. What science and research have you done that is a credible alternative to current science??
That is a very different dynamic because most of the sea ice in Antarctic melts every year anyway and that does not threaten to warm the planet like the warming of the Arctic does. The bigger concern in the Antarctic is the accelerated warming and thus melting of glaciers in western Antarctic.
That Part ,where the ICe FLows Out!!.... NEEDS to BE BLOCKED. . The Many items created? .. Need to create a BLockage or something to control this from happening
We don't advocate geoengineering, there are too many possible unintended consequences of putting those metals in the atmosphere at quantities large enough to change the atmosphere.
Not beyond that year, but as Arctic ice cover continues there is increased possibility of strong winds pushing sea ice around causing to melt quicker leading to less and less sea ice. Soon there will be none in summer in maybe ten years which is hard to predict. There is still a lot variability in the Arctic!
What a cool animation. Almost like a heartbeat. That final image is a little terrifying.
A few Facebook prayers should be able to fix this.

I'm interested in why at the end of the video, you chose only 2 comparison points? Why and how was September 1984 chosen vs September 2016?
They are just showing the start of their data gathering vs the last record. Clearly it's melting, but what the cause of it is still up for debate. Many argue that this melting is caused by humans. Some argue it's simply normal for the EArth's atmosphere to fluctuate. We really don't know. We do a lot of speculation on both sides of the argument. I'm on the fence, it could be a combination of things outside our knowledge. I think we should do our best to reduce creating greenhouse gases but let's not kill each other over it. I personally believe these things sort themselves out. Whether it be war or famine but something's gotta give sooner or later.
There's no debate over this. It's global warming.
@@timothyandrewnielsen the last record was 2017. That's disingenuous.
@@noahwilliams8996 There is a debate as to what the cause is, my brainwashed friend.

No, there's just one side having science, and the other being ignorant fools who are going to doom humanity.
Dear Dr. Walt Meier of NASA Goddard Space Flight Center. Please allow an answer for my following question. The years of this timelapse film are from 1986 to 2016? Is that right? More importantly, at some point the mature ice takes a sudden decline and never recovers, can you provide a specific time for when that stark drop off appears to have occurred and what events may have been going on globally leading up to and during the time of this dramatic sea ice loss? P.S. I can look provide the time stamp as referance if you cannot deduce what point in film im referring to but I very well believe you capable! Forgive me if I remembered the beginning and end years incorrectly. Thank you for your dedication and passion.
@SaRa. This particular graphic starts in 1991 and runs to 2016 and starts again at the same time at 1:16 showing the year in the left hand corner instead of the color code reflecting the muti year sea ice.
Interesting video! It would help to highlight the important parts you are talking about.
That's what happens to you when you mess up with Titanic!
bahahahah this is gold
RIP thicc ice
Take plastic from the Great Pacific Garbage Patch and create artificial ice bergs to reflect light from the arctic circle and it will cool down and form more ice. Could make floating plastic dens built into the plastic ice bergs for the polar bears to use as well.
It's like watching the planet trying to breath. But every breath becomes thinner and thinner, and brings less oxygen to the lunges than the previous. Literally watching the death of a planet.
I need to refill my glass.... brb.
Just drop a huge cube of ice in. It'll be alright.
Well that's terrifying.
oops.
Would they prefer another Ice Age?
Have you done an update to 2020?
Good job destroying the planet humans 🤦🏾♂️
It's a good thing you're not a human!

How can politicians look at this and not believe in climate change?
The same way a lot of average citizens are in denial.
NASA also said is hard to measure ice, thickness, and yes you can look it up so i´m worried about everything.
That something is hard is not a reason not to do it. IceBridge has been using lasers to measure thickness for years, and IceSat2 will do it globally from space. Lasers!
We got to take the Futurama approach and drop a really big ice cube in the sea yearly. that will solve all our problems
holy grail at the center of the dish? and why is that horizon cut all weird
A good visual illustration of our impact on our home.
And yet the oceans have not risen.

You're aware that Greenland exists... right?
Is there any possibility to access the source data behind this video? E.g. as a GeoTIFF, NetCDF, gridded binary, ...? Thanks!
You can download datasets and images from the NASA GISS website: data.giss.nasa.gov/
Lol we're so owned

Yueh knoe according to climate science that started all this was about 25 years before that. We should be all done frozen over by now, but noooo! Wayyy too many keyboard climatologists in the "Tewb" anymore...good luck all see ya all on the bright side.
stop it. Stop this. get off your butts and change things, and quit your WHINING.
@@jasonmartin4775 you do know its a computer simulation right sport. All data man made and input into the computer to output what they want you to see.
This is no joking matter. The consequences of inaction will likely be shortages, then hunger, and finally starvation in the industrial countries at some point. Planning now might reduce that likelihood. Contact your representative and let them know you are a single issue voter.
This is a great animation, thank you guys. I think it's important to mention the "during the era of satellite measurements" - I mean, how can we make sure this relates to human activity ? Also, from what I've read on the Nsidc, isn't the Antarctic ice at the south pole increasing ? Not questioning the climate "change", just questioning our responsability in all this, thanks.
Was Gibbs Helmholtz equation used to measure the melting in this research?
in the same time-frame the south pole has grown by an amount larger than that of the north poles shrinking
barrettdesigns thats actually not true, the antarctic is growing slightly (due to the ice melting and making the water less salty, therefore making it easier to turn into ice) ,but it is not growing fast enough to outgrow the arctic melting, and soon that thin ice around antarctica will melt too...
You're making things up. Antarctic growth has outpaced north pole's shrinking.
Thecl Artic is perfectly healthy and record this winter too. It's all natural cycles. We're likely entering a cosmic ray indused little ice age, brought on by incoming weak the sun cycles.
That's not accurate. f you wish to compare, Antarctic ice (land and sea) has been growing by about 82 gigatonnes per year for the last few years. Greenland alone has lost an average of 238 gigatonnes in that time range. www.nasa.gov/content/goddard/nasa-study-shows-global-sea-ice-diminishing-despite-antarctic-gains Antarctica gained 82 gigatonnes of sea ice per year from 2003 to 2008. Greenland alone has lost an average of 238 gigatonnes per year from 2002- 2015, and that's land-based ice cap, which contributes to sea level rise. www.nasa.gov/content/goddard/nasa-study-shows-global-sea-ice-diminishing-despite-antarctic-gains www.arctic.noaa.gov/repor.../greenland_ice_sheet.html More recently, however: www.nasa.gov/feature/goddard/2017/sea-ice-extent-sinks-to-record-lows-at-both-poles
Based on your own numbers the 82 gigatonnes of sea and land ice per year. Your comparison dataset is 2002-2015 which is 13 years. 82 gigatonnes times 13 years equates to 1,066 gigatonnes which is vastly more than the 238 you mention. Your second comment references 238 per year so youre either misrepresenting your data or intentionally being confusing to swindle the public. Personally, I'm pleased to see the NASA mission reset back to its core. I'm tired of tax money being wasted to swindle the public on fake environmental concerns.
But, is it possible to use the temperature change to somehow encourage ice growth?
I notice that this NASA video is an animation. If only there were a government agency capable of taking actual photographs from space...
David Bolger
Taking millions of pictures of the North Pole from literally the same exact place for 32 years for no reason because clouds will cover everything anyway doesn't seem like a great plan to me.
Everybody leave your freezer open make the earth cold
...which means that at some point the meltwater entering the north Atlantic will trip the NAD, which means an Ice Age for the northern hemisphere.
Yeah, Europe will get colder, but more equatorial regions will become inhabitable sending waves and waves of "climate refugees" to colder regions. Coastal areas will also flood causing people to move inwards. All this movement will cause demographic catastrophe. There will be wars for resources like water or food. All in all this is terrible news for everyone.
we don’t know exactly. To my knowledge the best current estimate of what will happen is Hansen 2016: www.atmos-chem-phys.net/16/3761/2016/
It also lists the uncertainties which still need to be addressed to get a stronger estimate.
Why dosent the sea rise then? By our coast it has been the same since I was a little boy..
Has it really though? Or did it change slowly enough for you to not notice?
The sea level has in fact risen enough to engulf some inhabited islands already. This received little media attention but there are people permanently homeless due to changes that never happened in all prior known history.
Amazing video, theres no thick ice left. Same probably has happened to forests and animals living in forest. Beside these we get new land made of plastic in the oceans. We might be doing something wrong?
I thought Ireland was under ice during the ice age? Or does this model ignore northern Europe?
Also, the amount of thick ice at 1:03 looks a lot less than in 1993. What is this model based on?
Mourning Ireland NASA's Polar orbiting satellites took images of the ice extent and thickness over the last couple of decades, these satellite images were used to make the animation you saw.
we're so dead.
Only a very small number of people realize that right now.
It's just a little plastic bottle how much trouble could it really cause
Looks like it just goes through long cycles.
What the Arctic is doing is cycling DOWN to the point when there is no Arctic sea ice in the summer which will lead to greater warming for the rest of the planet. That will come sooner then you think.
And as the Arctic warms still further we will see the release of methane in massive quantities which will accelerate warming!! COMPRENDE???
dang. thanks for the video
Christ, this is really sad!
Just like when you watch you snowman on Sun 😥
7 350 000 000 people today 1 000 000 000 every decade that's it! !
Imagine earth without humans
So what? we need more and cheaper Chinese products. The Northwest Passage can be pretty handy.
what about Antarctica? any time laps like this available?
It is not as dramatic as this video because most sea ice melts back around Antarctica every year. The bigger concern with Antarctica is the accelerating melt rate of land glaciers in western Antarctica.
glad i'm an old hippie and grew up when i did.
You have to remember that what we are seeing is a computer animation that is sped up. Not a time lapse. That might not seem important but it is. A time lapse is when a camera 'captures' and records an event. This is an animation that was preprogrammed to do one thing. Most of you know that a camera was not actually perfectly affixed above the earth in the same spot for 30 years, but face it; you know plenty of people will think so. And their vote is just as powerful as yours. You have to be reliant that the data that was plugged into the animation and trust that it's accurate. One of the problems I see is that although we have had flooding in some areas, it has not been unprecedented. We have been told again and again to anticipate massive population displacement but the amount of arctic ice simulated to have melted has not resulted in the flooding we should have expected from it. Then there is the famous photo that Al Gore carts around which shows an ice shelf grown to the shore from atop a mountain 40 years ago, and he then shows a newer photo of the same area that shows how much the ice has retreated. Then every year, someone goes back in the winter and snaps a new photo of the ice returned, only to have an alarmist go back in the summer and show it had retreated again. And on in on it goes. Global Warming continues to run into scientific problems when what people should be most concerned with is actually the depletion of natural resources. Natural resources that are either becoming scarce due to deforestation, urban expansion, relentless mining, over fishing, poisoned waters, poisoned air, etc. While we have this major push for climate change we have virtually NO push to change that we have killed off 70% of earths wildlife since 1950. State-run medias take turns highlighting each other's war crimes but no anti-war movement will make the news. Customers find themselves bled dry as they are forced into new energy markets, all pushed by 'clean energy'. But no one will talk about a clean planet that is dying more and more each day. The UN recently passed legislation which requires vessels visiting Antarctica to first register in order to "preserve" the continent. Thus far, very few private institutions have been able to gather private research. Only government agencies have been permitted to enter.
What satellite is the sea ice data from?
The “Daily image update,” as well as many of the images shown in Arctic Sea Ice News & Analysis, are derived from the Sea Ice Index data product. The Sea Ice Index relies on NASA-developed methods to estimate sea ice conditions using passive-microwave data from the Defense Meteorological Satellite Program (DMSP) the Special Sensor Microwave Imager/Sounder (SSMIS). The basis for the Sea Ice Index is the data set, “Near-Real-Time DMSP SSM/I Daily Polar Gridded Sea Ice Concentrations,” and the NASA-produced “Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Passive Microwave Data.” For more details, see the Sea Ice Index.
Why is the Sea Ice Index product used to study sea ice?
The passive-microwave data used for the Sea Ice Index is especially helpful because the sensor can “see” through clouds and deliver data even during the six months of Arctic darkness and frequently cloudy conditions. Some other satellite sensors cannot penetrate clouds to take data, so the results are sporadic and dependent upon weather conditions. Still other sensors can see through clouds, but they do not cover the entire region of the globe where sea ice exists every day, making near-real-time monitoring difficult. Furthermore, some sensors cannot provide information in winter, when polar darkness prevails.
The passive microwave sea ice record dates back to 1979, one of the longest environmental data sets we know of. This provides a long-term product that consistently tracks changes in the ice cover over many years, lending additional confidence to the trends that we observe. So, although NSIDC refers to additional satellite data in developing our analysis, we primarily rely on passive-microwave data for Arctic Sea Ice News & Analysis images and content, and for tracking long-term change.

Sea ice melt does not cause sea level rise. Land ice melt, such as Greenland, does that.
So many comments talking about building a wall on Phram's straight that I'm scared someone actually believes it to be a solution.
Uneducated people often dwell on nonsense or absurd suggestions to avoid facing reality when it is their own lack of understanding that is the problem!!
I, for one, welcome the day when we have an ice-free Arctic. Will be a major boon for economic progress and will shorten trade routes.
We still have a LONG way to go until we reach the conditions of the last interglacial. The ice age of Greenland being the dead giveaway in that regard.
The current warming of climate and related Arctic ice retreat is occuring much faster then occured in the past interglacial periods. When the Arctic becomes ice free in summer then the albedo of the Arctic will be near zero and almost all sunlight will be absorbed by the Ocean warming and in turn warming the rest of the planet still further. And with GHG's contiinuing to rise in the warming the climate will continue to warm from that cause. As the Arctic sea ice withdraws from the Arctic this allows the waters to warm and allowing for the potential and rapid increase in methane release from the permafrost. Peter Wadhams who has studied the Arctic for almost 50 years reports that the release of this methane could come as a dramatic spike in methane levels, a methane bomb as it were which could raise global temperatures by 0.6 °C in a short time.
This is what years of research on the changes going on in the Arctic has indicated is a real concern.
What science and research have you done that is a credible alternative to current science??
Im sure this has happened b4 not like we have had the ability to watch this in the past.
this was cool---now show the timelapse for antarctic
That is a very different dynamic because most of the sea ice in Antarctic melts every year anyway and that does not threaten to warm the planet like the warming of the Arctic does. The bigger concern in the Antarctic is the accelerated warming and thus melting of glaciers in western Antarctic.
can you show me 25 years time laps ?
That Part ,where the ICe FLows Out!!.... NEEDS to BE BLOCKED. . The Many items created? .. Need to create a BLockage or something to control this from happening
Where is the 300 ft wall around the circumference? Must be fake.
So when did it disappear? It's still there at the end of the video....
it does not say it dissapeared, but dissapearing
Diego So it shows that things change and nothing is static. Got it.
Many ancient species lost in the sea..
Cant you just spray a blanket of Barium and Aluminium in to the atmosphere to reflect the UV rays?? It would surely slow down the melting?
Its surely safer than millions of people losing their homes to rising ocean levels!
We don't advocate geoengineering, there are too many possible unintended consequences of putting those metals in the atmosphere at quantities large enough to change the atmosphere.
Why everyone so scared of change? Sheesh...

Is it really this hard to type "negative effects of climate change" into the search bar?
Is that sarcasm or ignorance? Just curious.
If the melting Arctic ice is causing a serious problem, why don't the scientists and researchers try and do something about it?
Silvia Logan
That would be the government's job... the scientists and researchers are there to do research, not to lead countries.
Still there in 2024
great job!
RIP Earth.
Would the stong artic cyclone back in Aug 2012 have lasting effects?
Not beyond that year, but as Arctic ice cover continues there is increased possibility of strong winds pushing sea ice around causing to melt quicker leading to less and less sea ice. Soon there will be none in summer in maybe ten years which is hard to predict. There is still a lot variability in the Arctic!
it'll come back
