- The Arctic is the rapidly melting front line of global warming.
The island of Spitsbergen in Svalbard, Norway, is warming around three times faster than most places on our planet.
Understanding how and why it's melting so fast could hold the key to preparing the planet for our changing climate, ITV News' Science Correspondent Martin Stew reports.

Greed kills the earth
Shows how intelligence the wealth are lol
Whole world was warned already 50-60 years ago to START MAKING A CHANGE, everyone laughed... in the end of this decade most of world will cry... what a slap from Strong Irony...
The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p
@@OldScientist all statistics are statistics untill time comes and makes a point that statistics are worth 💩 🙃 what i see and feel personally it never was like it, how it is now ,weather mostly feels unpleasant changes drastically and people will accept facts when its too late as always. 🙃
...same 💩 in economics. New years numbers statistically are nice but but inflation jeeps earing all alive ... because they use just previous year to compare instead all time... so numbers will always lie..
@@DT__1 Lived experience and anecdote are no substitute for scientific data. A process of improvement in any situation has a better chance of success when it is based on objectively collected information rather than how an individual feels.
@@OldScientist Just for the record. Are you a paid actor?
Climate change is the most critical issue in the world, all countries must uphold the principals to cut CO2 emissions and less depending on fossil fuel for energy.
Really, please explain to me the physics of how greenhouse gases warm daily atmospheric temperatures.
Please advise at what atmospheric concentration of Co2 does it produce its greatest warming effect ?
Based on the ice core data is it rising Co2 levels which drove up temperature or rising temperature which drove up atmospheric Co2 levels ?
Are current temperatures warmer than they have been for most of the last 8000 years or cooler than they have been for most of the last 8000 years ?
Lets see if you know anything at all about this subject.
Though looking at your post i rather doubt you actually know anything about the subject at all.
@@teyhoonboon5853 How?
@@neriksen This is a general knowledge, go and find out in library or Google search in handphone.
This next decade or two could be the most crucial in all of human history because our choices now determine which way we go; horrible extinction in one or two millennia or much cleaner, healthier, sustainable environments all around the planet, powered by abundant cheap energy. Arguably the dawn of a new and much better era.
Rubbish the unreliables produce neither cheap or abundant energy, wind and solar are toxic time bombs that destroy the environment.
What you have just posted is childish propaganda, the reality is the exact opposite.
The most expensive forms of energy available are wind and solar.
If you want a greener environment pump more Co2 into the atmosphere.
Save Our Planet Now
Save humanity from those fools who think we have a climate problem.
Missing the point as usual. The surface of the ice is more underwater and the temperature of the sea is more important than tempersture of outside air temperature, so the situation is far worse than meets the eye
Great to see so many diverse cultures working as a team. 🙏
Uphill struggle now, due to the problem being ignored for 29 years!
29 years? Much longer than that kiddo
What struggle? Data proves that humanity has never been safer, healthier or more prosperous than at anytime in history.
8°c in 50 years is insane. I don’t believe humanity in any form close to how we know it will continue for another 50.

The endless climate mantra: "Just you wait, it's going to be bad, you'll see". Repeat decade after decade in perpetuity.
@@anthonymorris5084 it’s bad now, records are being broken every day. There’s flooding in UAE 🇦🇪 it’s 38°c in Australia winter, Central Europe has had 10°c anomalies all summer. This is the year it’s supposed to be colder as it’s a el Nina. This is happening now.
@@Jonnyturboable My friend there are many places experiencing record cold summers, like the city I live in.
The UAE is a desert. It receives flash floods. 40 years ago there was nothing there but sand. It was a tiny fishing village and if there was a flood I can assure you, you would never hear about it. There is simply more cities and structures for nature to flood. It's called the 'bullseye" effect. Google it.
The only thing getting worse is media coverage which seeks out every single natural disaster it can find to shove down your throat.
The Earth has warmed by around 1C over approximately 200 years. This is imperceptible without scientific instruments.
@@Jonnyturboable Nothing is happening which is in any way unusual with weather during our current interglacial over the last 8000 years NOTHING !
Records are ALWAYS being broken somewhere thats normal.
What IS important is the long term data.
WHERE was it 38 Deg C in Australia ?, how was the temperature measured, what size was the Stevenson screen? , where was the Stevenson screen located, was the data homogenized ?
If you do not know the answer to these questions whatever you heard on the news is meaningless, because our BOM has been engaged in very unscientific practices for decades to produce an impression of a greater rise in temperatures than there have been.
Therefore without that information you cannot make a value judgement as to the accuracy of what you heard.
This winter here has had fewer frosty mornings than some years BUT....
the problem i have as a biologist in this topic is the worlds getting warmer with or without us, we have just come out of an iceage event, with 3 miles of iceshelf where i am today, great yarmouth on the norfolk coast, then there was the big thor, what is the North Sea today was a very fertile grassland plain the went as far as they eyes could see with massive primary biomass enough to feed the wolly rhinos and mammouths that roamed these vast plains.
These ice age events have been going backwards and forwards for at least 5-6 times over the last million years or so, the earths means of keeping cool, it will happen again colder and longer then the ones before. Where do we humans come into all this, little at best, our crimes against the natural world is mainly habitat lose and with it the mass extinction events and population explosion, from 1 billion to 8 now uncontrolled growth and not the resources to deal with such a surge of a large mammal, omnivores too which means everythings on the menu.
The world wants rid of us, as quickly as possible, by what ever means, disease more then likey, then the world can return to pre us, the silence will be overwhelming, so make it soon, luv to come back in a few hundred years to see the transformation, will be paradise on earth at last, we were and are a mistake, it wont happen again
The world climate has changed over the billions of years. Sure. What is different right now is the speed of change. In my area of the world; when the glacier retreated 9-7000 years ago, it took two thousand years to retreat 100kms. The world ice belt retreat, the world temperature and the acidity of the oceans are all increasing at an accelerated pace; With major change in only the past few hundred years and a brisk acceleration from the 1980s forward. That these accelerated changes are attributed primarily to the use of fossil fuels is why we need to change power sources. Not that hard. So I wouldn't write off the human race yet. cheers.
Mother Nature is amazingly all powerful.
Man will never control her, not now, not ever.
All we can do is adapt.
If they would just dig down, they would find trees old trees. History repeats itself.
It was once full of life, and then it got frozen, and now it's Coming back to life and we can't accep it.
The aerosol masking paradox makes abundantly clear that it is over. The heat is locked in & there is no way out. Ditch the hopium & begin the mourning process, accept our fate & be kind to others, we're all going to need help facing these end times.
Really, i suggest you do some basic physics research.
I doubt you understand the difference between long wave infrared radiation and heat.
Please explain to me in physics terms how the greenhouse effect is supposed to work.
How about the truth?

By drilling in the oldest ice on earth we now know the atmospheric carbon content YEAR BY YEAR 1,1 million year back by measuring air trapped in the ice. Incredible considering Homo Sapiens only have been outside the African continent for 65.000 years. It´s not only the atmospheric carbon content locked in airbubbles in the ice, that we can measure, but also things like pollen, ashes (and often from where these ashes are from, is it from volcanoes or people burning coal in their 18 hundred stove heated apartments in London etc). Therefore we KNOW that there have been three times in last 1,1 million years where the atmospheric carbon content have been raised by up to 30 PPM carbon content over the 220 PPM the planets regulating systems prefer by large global volcanic activity and EACH time it have triggered abrupt climate changes that have lasted thousands of years until the planets regulating systems slowly have brought the carbon content back to 220 PPM again. As these activities have happened they were followed initially by large forest fires and the pollen types found shows that a lot of bio diversity have been knocked out and replaced with more simple grass types as the conditions for trees and bushes and flowers abruptly have changed in a matter of very short time.
The great thing about scientific knowledge are that you do not have to guess but can refer to accumulated knowledge obtained.
The problem we have, are that sinister forces, not least hereunder the fossil fuel companies, have invested billions last 70 years, since they realised the scientific facts of what consequences continued use of their products would cause, to lie, dis and mis-inform so that you today can write a comment like you just did instead of having the correct information.
I repeat! It have never been a winning strategy to put your head in the sand when your house is on fire!
Our house is on fire. WE are OUT OF TIME!
Climate tipping points are triggering and if we do not reverse them NOW we might not be able to recover before we end up loosing our atmosphere, as it happened on Mars, we are heading fast for a disaster we only can prevent if we ACT. We HAVE ALL the needed knowledge and technology to prevent it but as long as we do not even see some nations stopping to subsidise fossil fuels and thus prevent the now cheaper emission free solutions from even taken over the market naturally we might not make it. I cannot stress enough that it are NOW or we are running out of time. The atmosphere do not care what sinister people decide behind closed doors, it simply respond to the massive amounts of carbon we spew out.
Google: What are the atmospheric carbon content right now" and understand that we have not even stopped the leak at planet Titanic. Atmospheric carbon content are still accelerating upwards! Stop having unfunded opinions and understand the scientific proven reality of our dire situation!
The point are we do not have to go back to the stone age at all, actually that are what we can prevent by acting NOW! Worlds largest transition project are based on offshore windmill parks and thus green bulk electricity and green hydrogen production. This project will transition 220 million Europeans inside a decade and are ongoing now. Nothing prevents nations like USA, Canada and Australia from making a simple copy/paste of this project. WHOM convinced you that it are a good idea to keep spewing out carbon emissions and send your hard currency to human rights abusing oil sheikhs in the Middle East, when you could produce emission free energy at home and create good stable tax giving jobs at home? Last fiscal year USA, as a minimum, spent 790 billion US tax Dollars on SUBSIDISING fossil fuels. I would estimate that Canada spend something similar and Australia even more per capita. These subsidises creates an unfree market that prevents the cheaper emission free solutions to spread. That are downright bonkers and do not benefit Australia, USA, Canada nor it´s populations. Relate to FACTS! Facts are that we NOE have passed insane 420 PPM carbon in our atmosphere, still rising. Thus Humans in a little over 200 years have raised atmospheric carbon content with not, 30 PPM and not 100 PPM but insane 200+ PPM!
Are you sure?
@@Mike-zx1kxindeed, this won’t end well.
@@chesterfinecat7588 of?
@Mike-zx1kx "The great thing about scientific knowledge are [you mean 'is'] that you do not have to guess but can refer to accumulated knowledge obtained." This is exactly what I have done in some detail, with numerous references (something you have not done). My data shows there is no calamitous warming taking place in the Arctic at present, and there was nothing in your written meanderings that disproved that.
On another point, it may be that your first language is not English, but can you please learn to decline the auxiliary verbs 'to have', 'to be', and 'to do' correctly? For example, it should be "it has" not "it have". Many thanks.
Tens of millions many of them children starving to death right now . Shouldnt all these global leaders if they are so concerned with humanity be solving this first ?
Sadly feeling powerful is more important to them
2 billion without access to safe water , think anyone cares ? Fixable for a hundredth of the worlds military budget which is presumably being spent to protect us ..how sick is that !
The idea of global leaders is to keep global unrests alive for as long as it is possible... simple people are too ignorant to make a change by them selfs,so no leader is going to do something as well...
The climate change caused extreme weather will soon, it can be next year, in 5 or maybe 10 if we are "lucky" cause several large farming nations harvests to fail at the same time. We currently feed 8 billion people a year. In the event of these multiple harvests failing 100 of millions if not several billions risk famine.
WE HAVE ALL the knowledge and technologies to make a complete and fast transition to an emission free energy production and usage. The worlds largest transition project, signed January 2023, are ongoing now and will transition 220 million Europeans in just a decade by raising off shore windmills in the North Sea. On top the worlds largest green hydrogen production. Hydrogen can replace both gasoline and diesel and only emits water when burned. The three large nations with highest greenhouse gas emissions per capita are Australia, USA, Canada. ALL three nations SUBSIDISES fossil fuels in 2024 and not one of them have laid forward a plan to live up to their commitments in the Paris climate accord. All named nations have close to same great options as the worlds largest transition project builds on. It´s more than fumes from fossil fuels that stinks!
It have never been a winning strategy to put ones head in the sand when ones house is on fire! OUR house is on fire!

Embrace democracy and capitalism and the poverty goes away. The path to wealth and prosperity has been laid out for more than a hundred years.
Living in the Southern hemisphere we are all too aware of the fact that the winters in Antarctica are getting warmer - not warm by human standards but warm enough for penguins not to breed as usual - smaller numbers
There is no evidence at all, that penguins aren't breeding due to temperature rise. Almost all of these situations are proven to be the result of starvation, due humanity's drive to empty the oceans of every living creature through overfishing. All to service the needs of 8 billion people and growing.
Winters in Antarctica have been getting COLDER for more than thirty five years.
Check the data !
I also live in the southern hemisphere.
There has been NO reduction in penguin numbers in Antarctica, colonies have simply MOVED.
All the electric cars I see are the size of a BUS !!!!!

Why is the Arctic, "The front
line"?
It is called Arctic Amplification - Arctic is warming 3 to 7X times faster than the rest of the world.
The mechanism is quite simple - google it if curios
Do you know what is going on in the arctic areas?
@@imtheeastgermanguy5431 No. Why is it the front line?
@@jamemswright3044 arctic areas warming up much more than the rest. Less snow and ice and higher temperatures are not good for arctic areas. You know that those areas are very important for our climate, food and earth
@@imtheeastgermanguy5431 OK. So the fabled polar amplification. If polar amplification is true, weather systems around the planet should be reduced in strength. Due to the fact that weather systems are powered by the difference in energy from equator to poles
Where can I find the long term data for snowfall and temperature in the polar regions?

Nice!
Great lads. Where were you a few weeks ago when the UK locked up folk for five years for explaining what you do in this video to the jury.
And they deserved those sentences.
This video has even less scientific credibility than Just Stop Oil.
The greenland land ice melting in significant % will be kind of the last thing to happen, pretty much every other tipping point happening before that
Melting ice doesn't kill anything.
It melted way more when the vikings were there. They moved out when it got cold again.
Which will be coming soon enough, dont worry.
And the people in the boat powered by an Ice.
Cold 🥶is colder and warm became hot 🥵.
Was that 8° rise in C or F?
You have no idea what coming . Lol
We don't need all this bs about "leadership". This is not a national issue. Outside the EU, the UK is insignificant.
We all need to make a sacrifices so that billionaires don’t need to change their lifestyles.
Who gives a F ? But nice petroleum-fueled boat you have there.
Glacial ice has been melting uninterrupted for 10,000 years. Nothing died. Life flourished.
Crackpot climate science denier. It is warming 200 times faster that would naturally. The cause, us humans.
@@denisdaly1708 What did I deny? Where did I deny anything? What science did I deny? Where did I deny it wasn't warming? Where did I deny humans weren't a cause?
Crackpot climate zealot, who, like a programed zombie reacts emotionally, lashes out and calls everyone a "denier".
My statement is 100% accurate and backed by science, making you the denier.
Nowhere is there an ounce of evidence that it's warming "200 times faster that would naturally". That's hyperbolic nonsense.
Yes but you said nothing about the rate of melting. I guess ignorance is bliss isn't it?
@@boblatkey7160 According to the NASA graph right in front of me, the first 6,000 years of melt was rapid. Likely due to the incredible amount of ice that was melting. Mile thick ice right across the entire northern hemisphere all heating up.
The latter 4,000 years of this melt slowed dramatically. This continued to slow for 4,000 years. There has been a very slight uptick over the last hundred years but on a geological scale there is hardly any ice left to melt.
According to NASA the ice is melting at 3.4mm per year. This is imperceptible without scientific instruments. It's less than half a meter in a hundred years. This can hardly be characterized as a "crisis".
25% of the Netherlands already sits below sea level. The Dutch aren't dying, drowning, fleeing or turning into climate refugees. Why? Because they are a wealthy and prosperous society, which is what keeps us safe. Warming isn't the threat, poverty is the threat and all climate policies induce greater poverty.

No such thing as global warming
Really ? Take time to read publications. ..
even outside of the climate emergency, global warming is kinda why our planet has livable temperatures. It's just that in the past century we've been adding towards greenhouse gases to the point where the warming is way too much. Without ANY warming, our planet would be as cold as space. I could explain the proccess if that would help.

Why do you automatically, in zombie like fashion, accept without question, that warming in the coldest, deadliest and most uninhabitable place on Earth is a negative?
Because it's a global system, and we've changed it faster than the asteroid impact.
It's not "automatically" and "in zombie like fashion." You're projecting - that's what you're doing. Worse, you don't even have evidence. It's after decades of research, and after the fossil fuel projections from the 70s have proven accurate.
@@subcitizen2012 Science tells us that the planet has warmed by around 1C in approximately 200 years. This is imperceptible without scientific instruments.
The speed is meaningless. Countless millions of plant and animal species across the entire northern hemisphere, experience temps that go from around +35C down to -35C in just 6 months. Nothing dies. This can only be described as rapid and dramatic climate change. Life experiences serious temp changes just from day to night. Nothing dies.
Life flourishes under warming. The greatest diversity of life on this planet resides in the tropics not Greenland. Millions of species across the northern hemisphere are experience habitat expansion for the first time in modern history all because of warming.
*"Worse, you don't even have evidence. It's after decades of research, and after the fossil fuel projections from the 70s have proven accurate."* What evidence and research are you referring to?
