NASA | The Arctic and the Antarctic Respond in Opposite Ways 

I just want to see some footage of Antarctica from out of space...

Damn I wish this was longer... felt like they cut it short. I'd like to see a more detailed discussion of this.

About your title: Antarctica: HELLO FROM THE OTHER SIDE Arctic: WHAT

You got that? The ice caps are the "canary in the coal mine" when they're shrinking and they're not the "canary in the coal mine" when they are expanding they're a "bit of a mystery." LOL

Wow...Too many questions to ask about this video...will check back tomorrow with top 2!

"this year" That's all I needed to hear. Thanks.

Could it be that the antarctic ice is spreading because the ice on the landmass of the antarctic is sliding into the ocean? Of course the surface area is very important regarding the reflected solar radiation but I think the ice volume should be measured aswell not just the area.

LOL, global warming melts ice in Arctic but extend the ice in Antarctic.

Having a flashback to Al Gore's 2007 prediction that "all arctic ice would be gone by 2014". lulz

The answer is simple as to why antarctica is expanding 1/3 slower than the contracting arctic--> it takes longer time to build than to destroy. It takes a longer time to build a house than to smash it into ground. Formation of permanent ice takes a longgggg time.

GW scientist logic: As the global temperatures are rising, this makes the ice melt, and therefore the Antarctic shows a record gain in ice coverage.

Nice to see a graphic from Antarctica's winter compared to Arctic summer side by side. That makes the difference leap out now does it not? Not implying anything here, just saying right should be right...

Milankovic Cycles. The North tilts closer to the sun for longer, by extension, the South faces away and vice versa.

What is the depth of the ice formation around the Antarctic in relation to the sheet on the main land? If the new ice is relatively shallow does this really mean the Antarctic is growing or is the melting under the ice sheet causing the fresh water to re-freeze giving the appearance of growth? Either way this is amazing to see. Thank you NASA!

just a question, why are they showing the earth rotating the opposite direction?

"The Arctic and the Antarctic ... are the regions where we see the biggest effects of climate change .. and the biggest effects of warming. This year the Antarctic sea ice has expanded beyond anything we've seen before and set a new record."

It has happen before, looks like the poles are going to invert again ?

This is the FIRST time I've heard of increase in Antarctic ice area, if true, it could be because the ice shelves are breaking up and ice is floating around in small pieces, or warm currents are shifting towards the equator, which will mean an increase in temperatures there, and more hurricanes etc.

'It's important to see the relationship between the Arctic and Antarctic because studying those gives us an indication of what changes were going to see around the rest of the globe in the future'... 'The increase were seeing in the antarctic is a little bit of a mystery' >>>> Its not a mystery! Global warming doesn't create ice.

Arctic vs Antarctic ice variations as mentioned seems confusing by intention by Nasa.

The difference in ice loss is due to percentage of landmass in the hemisphere I'd bet. On top of that it's way easier for ice to form over land than ocean.

These guys have a couple of decades of decent data and think they know how the polar regions work in geological time.

Interesting.

trending growth/shrink % based on original size vs total ice volume worldwide is a wholllle different metric. We aint stupid....give us the data...not mysterys unsolved and growth/decline yoy rates by sq mileage

Why no real pictures?

They know and are certain of so much but yet there are gigantic "mysteries" of such a scale.

The fact that this subject is still so unexplained makes it even more dangerous to consider not changing the way we live on this planet. I get people want to deny it, but it's like somebody not going to the doctor after have some serious health problems but passing them off as common cold...But we know the right thing to do is to see a doctor... study it , understand it, and change the way you live to further prevent a serious problem.

You guys should start doing documentaries. There's lots of people who would like to see what you guys have to say.

The artic is an ocean surrounded by land,the Antarctic is a land surrounded by ocean..........different,quite different......your comparing Apple to an orange!

"The increase that we're seeing in the Antarctic extent is a little bit of a mystery, we're seeing overall temperatures warming around the globe - so you would expect to see ice loss . . ." Maybe perhaps some of that peer-reviewed data and numerical information is slightly flawed?

Question: I heard that there was a bit of a hole in our north Magnetic shield, could the ice melting be coming from our sun's solar flare cycles every 11 years? (I'd like a response from someone at NASA)

I want to live out the rest of my life in the South Pole. it's getting colder down there and I want to contribute to the research. It would be a blast no matter how you shake a stick at it.

Yeah. Didn’t even know that they were different

So let me see if I have this correct: This "scientist" said; Arctic ice melt is a sign of global warming. Antarctic ice increase (growth of ice not seen in decades) does not mean there is no global warming. Record rainfall: Global Warming Record drought: Global Warming Record snowfall: Global Warming Lack of snowfall: Global Warming Record low temperatures: Global Warming Record high temps: Global Warming Floods: Global Warming Hurricane frequency increase: Global Warming No hurricanes: Global Warming Storms and tornadoes: Global Warming Normal weather patterns: Global warming

One can just fantasise about solutions in this complicated world. It would be so good if some people could...while others could...

I am doing my best to keep an open mind, but I keep seeing highly subjective things used. If you compare the rate of decrease in the north vs increase in the south, the distance is greater but the surface area is the same. It's the sort of thing people use to exploit holes in the knowledge of others. Seeing these constant little sneaky tricks being used makes it hard to take their argument seriously.

The Earth is and has always been in a state of change from cooling to warming and back again. Focus on stopping pollution and drop the "Global Warming" bit.

how is this negative for me?

I do worried ANTARTIC , its cool place

Mini-ice age in the Antarctica?

And like every other prediction we are 5 years from this video and the arctic has gained ice.

Antarctic increase a mystery? What is happening in the Antarctic is the coastal water is evaporating and then falling as snow making more ice. So much of this warming idea comes from just the last 100 years, when we have pretty good record of the last billion years, certainly the last 500 million years. The average temperature of the earth has, for most of that time span, been 22-25 degrees Celsius. Average temperature today is about 14 (we are just coming out of a mini-ice age which is classified as under 12 degrees average temperature). Also, humans are a tropical species, we evolved for a couple million years at the equator before fire and clothing came about so to think a 2 degree temperature increase could be bad for humans is preposterous, humans (and life in general) thrive in greenhouse ages. Also, 450 million years ago we had an ice age in which there was 10 times as much CO2 in the atmosphere, so this idea that CO2 is warming the atmosphere (while there has been some correlation) is not yet conclusive, too many counter examples. For the last 18 years in fact there has been no net warming of the atmosphere, and yet 32% of all the CO2 humans have emitted since the beginning of the industrial revolution was emitted during that time. CO2 is around 400 ppm, its increasing very rapidly as my last statement showed, but the optimum levels for plant growth (including all trees and all our food and crops) is 1500 ppm nearly 4 times what it is today (side note: the average for the last 400 million years is ~2000 ppm) This has been my global warming rant, thank you.

This is so 2007

Seams to me that where going to eventually have another ice age.

what is this ? we gon ignore the fact that theres more ice than before and put it under ''mystery'' category and forget it and concentrate on the temperatures are rising causing ice to melt thing ? what is this ? this is called being biased

regarding Antarctic ice growth the scientist said "its a bit of a mystery we dont know" LOL...reason to 'pause' carbon tax until mystery solved by the trusty scientists

Since each of the poles are in complete darkness 6 months of the year, I still don't get why the reflective capabilities are emphasized.

Isn't it true that the climate has warmed several times over the last 800,000 years despite the recent warming being accompanied by higher co2 levels records show the climate has been far warmer several times in the past?

Ice redistributes itself and mother nature adapts.

How does the arctic ice decrease in the winter, when the temperature is continuously below freezing? How do you measure the loss of ice, year after year when the ice cap gain has been above average 11 of the last 13 years, and the polar ice this winter is the same in coverage and thickness as it was in 1978. In 1978, by the way, scientists insisted we were headed into a global ice age, based on a 20 year trend. Whoa. 20 years. omg.

Well, here it is, it is February 2020. The Arctic has sea ice that meets the mean as observed by the Danish Sea Ice Monitoring Office and the Antarctic still has that 'record' ice this guy was talking about. In addition, the Germans at the Neumeyer Research Station in the Antarctic tell us that the temperature has not changed upward except for one station in the northern most peninsula at Esperanza station. What should we make of this?

The global warming brigade conveniently forget that the ice in antartica is growing.

I love it

1:20 - What does he mean by saying "in the winter time" ? Of course there is no winter time if you speak about the whole Earth. There is a summer in the southern hemisphere while there is a winter in the northern of course

Temperature rises by 2 degrees so more ice melts. How brilliant. How much is lost through sublimation like the ice in a frost-free refrigerator ?

Part of the reason for the Arctic melt off would be the Ice Breaker boats breaking up the ice pack all year. 1 huge ice cube takes a lot longer to melt than several smaller ones, no matter what scale the ice cubes are viewed as

Were getting much more radiation from space ,the sun is in a solar minimum and the electro magnetic force field is weaking probably due to a magnetic not physical polar flip so the solar wind is not pushing even stronger radiation away

HAPPENING FOR BILLIONS OF YEAR ICE MELT THERE GAINS ICE ON THE OTHER SIDE

Maybe earth has a 100 year hidden cycle where arctic gets less ice and in next 100 years arctic gets more ice while antarctic decreases in ice.

I can't write right english, so... Creo que el planeta, gracias a su campo electromagnético, debe redistribuir el H2O según las diversas densidades atmosféricas. En este sentido es muy normal el comportamiento actual del hielo en la Antártica en contraste con el Ártico, ya que la emisión de gases es más densa al norte de la línea ecuatorial.

I think there needs to be some real study into why the antarctic ice is increasing on the same planet where the arctic ice is decreasing. Not speculation. Not politics. Just science.

As you probably know there is a tilt to the earth the arctic is currently tilted toward the sun and the Antarctic away so that means that the attic will shrink and the Antarctic will grow.

0:10 that guy swears

So much for "global warming". ;)

Ice age bad ! warm good, just ask Mongo, the ice aged hunter. People are stupid.

Could it not be the other way around. Can Antarctica melt so we can have more room for the population.

Information's polvs arcticvs In Black Box 🤫

wouldn't you expect the waters in the southern hemisphere to be cooler on average because there's less land.

What no one seems to be considering is that sea ice levels, no matter what they are - increasing or decreasing - play absolutely no part at all in "sea levels". Ice that is in water, because of buoyancy, is already displacing as much water as it would if it were melted into water. It's weight as ice, is displacing the same amount of water volume as it would if it melted. You can test this for yourself: get a glass, put a large chunk of ice in it, then fill it to the rim with water. When the ice has completely melted, the water level will still be at the rim of the glass. Melting ice doesn't add any additional water. It can't. The only ice melting that matters is what ice is accumulated on LAND, that melts and runs off into the ocean . And that is a small fraction of the total arctic, and antarctic ice that exists. Folks, ice melt is NO THREAT . On the other hand, the increase in arable land (ie, land suitable for habitation and growing food crops) is substantial, and actually a great benefit.

The land ice is melting and running over into the sea. It's putting a thin layer of ice on top of the Ocean and this is what is causing the "record", not that there is more ice than ever, just that it's gone from a stack on land to a thin melting layer floating in the ocean.

The Arctic and the Antarctic; ani means opposite

Does anyone else think 'farming' Brazil is a bad idea...shouldn't that stay Natural Rainforest? there has got to be a better way. clear cutting rainforest is a fracking disaster waiting to happen

Light on actual evidence. Again.

the earth gunna do what earth gunna do. we along for tha ride. quit feeling soo important. we`ll be long gone , and the ole universe will keep on spinin.

There has been no significant lower tropospheric warming for the past 13 to 17 years.

Hello NASA

Because there is more water vapor, in the atmosphere and the Antarctic was the driest, (desert) in the world,... pick up a hand ful of snow in Antarctic and its mostly 1000 plus years old. ... because of global 'warming' there is more smowfall in Antarctica, and it is not warm enough there for it to melt.

They just told us the Antarctic is the arctic 🤫

NASA | The Arctic and the Antarctic Respond in Opposite Ways

the ice increase is thin NEW ice...what you need to really measure is that thick ice the stuff that is stable,,,hundreds or even a thousand years old..if that old thick ice changes then that is what would be of worry..,,,that quick forming thin ice can melt or form so fast that it really wont indicate the big picture....the ocean water down there is really salty...salty water wont freeze as good as fresh water...the quick spike in the increase of that thin new ice is really due to as drop in sea salinity .

The sun burns hotter and cooler in cycles.

its simple, fresh water freezes faster than salt water and its also less dense. so the more ice that melts the bigger the ice cap its gonna look, well until the water mixes properly. then you'll see all you. is not bullshit it the real deal.

It turns out melt water is different than ocean water with regard to fact that it's much less salty. It doesn't mix and floats on top of the salty water and tends to freeze more easily than the sea water does. So the melted water causes the freezing events to make the overall size of the ice, a much larger area but it's largely due to the fact that the water is melting off the stuff that previously never melted off. The stuff that is freezing in subsequent years is the lighter less-salty melt-water. -- It's a fun quirk but the larger antarctic freezes are because of global warming. advances.sciencemag.org/content/4/4/eaap9467

CO2 concentration is higher (more people, industrial pollution) in NH as is temperature rise. Hence, the artic is rapidly melting. In the SH there is also an overal temperature increase, but not so strong as in the NH. Some regions show increased melting. sea ice extent has been increasing...due to? more fresh water in the ocean?

Not A Space Agency

Near the end of this video, NASA shows the earth turning backwards. How embarrassing, NASA.

Maybe the sea ice is increasing because the land ice is melting.

I still believe that Antarctica is getting bigger because it's growing underneath

Stop using what you called fossil fuel

The idea that the Antarctic sea ice expanding a percent or two over recent years is a red herring. The weather system in the Antarctic is different than the Arctic. The Arctic is water surround by land, and the Antarctic is land surrounded by water. Also much of the Antarctic continent is 10,000 feet above sea level. There is also a strong ocean current as well as prevailing west to east winds around 60 degrees South unimpeded by land around the globe. All of these factors contribute to Antarctic being colder than the Arctic as well as the continent being 3 million miles farther from the Sun during its winter months than the Arctic is during the Arctic winter months. If that isn't enough, in spite of all of this the Antarctic "sea ice" MELTS back to the ice shelves EVERY year.

Maybe it get's colder in the antartic because the heat around the equator pulls away the heat at the south-pole

Video is nine years old. Effect reversed. Not able to fear monger.

idk, it's too fast anyway, all the climate changes, they cannot be predicted, i bet this winter will be cold as fuck

The land ice is melting faster at SP, therefore there is a much larger body of fresh water at the ice edge come freeze time, so the larger ice is very bad, it's an indicator of how much fresh water has been lost from the LAND ICE. Sorry, I'm just a 46 year old savant, I see patterns in data ;0)

someone explain me what is happening with the ice in the south pole!

u know nothing Nasa Snow

You need to change the title of your video. seems how this year proved you wrong. Apparently you know very little about antartic sea ice. :) More then me, or anyone else. But more research is obviously needed. since its now at the lowets extent.. ever

lol

Wait the earth isn’t fLaT!!

Stop lying to everyone, we are not to be fooled anymore. Post real photos of the ice wall please, not CG animations.😀
