Speaking as an oceanographer in years past that is kind of a phony claim. It requires that both the melting of ice sheets and the warming of the oceans remain linear - which seems rather unlikely. In any event, warming doesn't have much impact on coastlines. For example: a 0.1% expansion in the deep ocean would be about 4 meters of increased water depth. But on the coast where water is shallow, a 0.1% increase in 100 meters is only 0.1 meter. The conclusion here is that warming has very little impact on coastline sea level rise and we really don't care about depth changes in the central oceans. It is still, in every place, the same mass of water.
arty san mobile Completely wrong for the last couple decades anyway. Maybe correct for 20th century before it got going. 2010-2024 Ice loss = 2.9 mm/year, thermal expansion = 1.6 mm/year, total = 4.5 mm/year.

Have all these " scientists " forgotten about the fact that we are in an interglacial period . In other words we will have a other iceage at some time in the future. All it will take is a few large volcanic eruptions.
If you really want the world to be aware, you should aggregate all of the melting ice around the world. Showing a couple of the biggest chunks really does not reflect the magnitude of the problems we're facing.
C3S reports that 1.2 trillion tons of global ice are melting annually, so 3.3 billion tons/day, and each pound of melting ice is absorbing 144 BTUs of waste heat energy. So, our AC is on "high" but, still, the planet continues to warm at the current rate of 0.214 degC/yr., so 1 degC every 5 yrs.
Glacial rivers prove that the ecosystem is working flawlessly. Thank God the ice is melting or all the fresh water on the planet would be frozen in ice! Nice to know the climate is perfect and we will never see sea levels rise...
When the melting gets down to the radioactive waste buried in the ice I'll bet they will be able to trace the flow under the ice a lot better. At least they will be able to be sure where it reaches the sea.

"There are huge non climate effects of carbon dioxide which are overwhelmingly favorable which are not taken into account. To me that's the main issue that the earth is actually growing greener. This has been actually measured from satellites the whole earth is growing greener as a result of carbon dioxide in the atmosphere. So it's increasing agricultural yields, it's increasing the forests, it's increasing all kinds of growth in the biological world and that's more important and more certain than the effects on climate." ~Freeman Dyson, Institute of Advanced Study in Princeton, New Jersey.
Greener may not be the end all that you seem to imply by simply stating favorability. Prime areas of rain forest in Brazil for example run the risk of becoming savannah and many northern forests are slated to burn. Water issues in many agricultural areas (too much and then too little) are typical of changes that can reduce the production of food. All kinds of shifts in climate at an increasingly rapid pace can overwhelm natural systems and lead to die offs including humanity. Good luck with your theory though. One can wish for the best.
There is always carbon dioxide in the atmosphere and plants take as much as they can use. It's the CO2 that plants are unable to absorb that's the problem for climate. Pumping more of the gas into the atmosphere isn't going to green the planet. Retreating ice and snow as the planet warms will also register as a greener planet.
A) it's recognized and taken into account B) simultaneously approximately 30 million hectares, 70 million acres of forest is being destroyed by insects and fires, farming. C) plants have lived and evolved for tens of millions of years when CO2 levels were much lower. Imagine if you double your intake of sugar? D) the biosphere source of all life is in decline across many species.

Very interesting. But the bottom line is this: the amount of snow that falls on Greenland each winter slightly exceeds the amount of ice that melts each summer. So sea level rise from the melting ice sheet is not a problem at this time.
I think you're wrong... the ice sheet is contracting... so it's opposite of what you say... less snow than melt. Look into it! Cheers and good life to you Louis... N
@@newtloken7884 Actually there is more snow than melt. The difference, is the amount of ice that flows into the ocean as a glacier. In some places in Greenland the ice sheet is contracting. In others the ice sheet is expanding. Impossible to know for sure what the totals are. We can only estimate. What is true is that sea level rise along the world's coasts, based on tide gauge data, is averaging about 1.8 cm/decade - and has been the same since the mid-1800s. The extra water is coming from somewhere - presumably both continental glaciers and the Greenland ice sheet.
Sea level rise... is far less than the movement of earth, eg in Sweden or the southern French coastline, medieval harbors are dry, while New Orleans and Venice are sinking which got nothing to do with the sea level but subsidence.
This is talking about global average sea level rise. There are many factors that can affect sea level in local areas such as isostatic rebound, uplift in tectonic plate margins, magma chambers, even ocean currents themselves. The people researching sea level know all this already.

They forgot to mention that we’ve had permanent bases in the Antarctic for about 120 years and every year they record an increase of 8 inches of ice per year. Every now and then there’s a bit breaks off the Vladivostok shelf because of excess weight and lever action and there’s a few bits melting due to thermal vents but all in all there’s a balance between that and Greenland which is why oceans have risen at a steady 3mm per year for as long as we’ve been measuring them.
Sea level has been rising at the same very small steady rate for the last 220 years. The industrial era has not accelerated that slow steady rise. If we put more money into mitigation rather than renewables that are not reliable, then we will be ready for any impact from that slow and steady rise.
sure thats the sea level changing and not the continent with the seashore, riding atop a tectonic plate (or several...) thats subsiding? ive never been able to tell what the ideal water level is in a container of no fixed shape or volume, and is constantly varying...
CO2 level rise accelerated from the 1960’s with the industrialisation of Asia. It isn’t a change over 220 years - it’s risen by a quarter over the last sixty years.
Humans have been surviving great floods for thousands of years. Biblical tales notwithstanding, nearly every early human culture has a historical recounting of floods or repeated great floods. Even if every American today drove electric vehicles and used electrons created only on virtue of nuclear energy, China (and India soon, too) brings two or three new coal-fired power plants online every month. *_TRUST !!_*
The Chinese communists encourage the “green energy transition” to cripple our industrial capacity, while they themselves continue to increase their fossil fueled industrial capacity to take over. Their goal is to be the sole source of manufactured goods for the entire world, which is to say, they wish to rule the world.
I am 49. I remember when I was in grade 7, that was the beginning of the fear of sea level rise. by 2000 we were going to be all living inland, I lived in the Fraser River Delta. Guess what.. there are still people living in the Delta
@@allangibson8494 You do know the permafrost line has been moving north (in a general sense) since the end of the last Ice Age and in a more specific sense since the end of the Little Ice Age in the mid 1800s, right?
@@kirklaird5020 And most cities were built on a land level that was just above sea level in the last two centuries. Rising sea levels are an infrastructure problem that needs addressing.
Not only does it snow, it snows in Greenland MORE in winter than it melts in summer. The process of calving is not only from "lubricating rivers", but from the Billion tons of New snow every year.
'The number one reason we are here is to make sure we use all the grant money we received, which in turn enhances our chances at receiving future grants. What? Oh, ice or sea levels or something.'
good documentary, but comments about lubrication or hydroplaning of the glacier on water are completely wrong. the water is under pressure at depth (rho*g*h) and decreases effective stress - also bouncy is in play for parts effectively floating on the melt water. the shear strength of meltwater, as a newtonian fluid, at the base of the glacier is zero. thus lubrication or hydroplaning are non existent
So, camping out in Greenland on NASA's mighty nickle...that about it? By the way, shouldn't The Danes be paying for this? Afterall, it is their island and its famously not for sale.
Kind of logical... except that Antarctica receives relatively little annual precipitation compared to the ice fields you mention. So outflow and inflow need to be kept in perspective before making that conclusion.
Want to end quote global warming turn of the power and go back to living life instead of feeding these people researching everything. Ya that harsh to accept but it would slow your concerns of quote global warming!
Perhaps, since we don't have tide gauge data that goes back that far. But according to tide gauge data that goes back about 200 years, sea level rise has been a pretty consistent 1.8 mm/yr since the mid - 1800s (world wide average along the coasts).
The melt/freeze/remelyt phenomenon makes sense and is so helpful in better modeling. Congratulations.

Every now and then there’s a bit breaks off the Vladivostok shelf because of excess weight and lever action and there’s a few bits melting due to thermal vents but all in all there’s a balance between that and Greenland which is why oceans have risen at a steady 3mm per year for as long as we’ve been measuring them.
Sea level has been rising at the same very small steady rate for the last 220 years. The industrial era has not accelerated that slow steady rise.
If we put more money into mitigation rather than renewables that are not reliable, then we will be ready for any impact from that slow and steady rise.
sure thats the sea level changing and not the continent with the seashore, riding atop a tectonic plate (or several...) thats subsiding?
ive never been able to tell what the ideal water level is in a container of no fixed shape or volume, and is constantly varying...
a source of water consistent with that steady rise - aurora interaction with ozone to form water.
Right on! People are panicking over a 2mm/year rise as if they don't have more important things to worry about.
CO2 level rise accelerated from the 1960’s with the industrialisation of Asia. It isn’t a change over 220 years - it’s risen by a quarter over the last sixty years.
@@bearantsTry again with actual chemistry…
Humans have been surviving great floods for thousands of years. Biblical tales notwithstanding, nearly every early human culture has a historical recounting of floods or repeated great floods. Even if every American today drove electric vehicles and used electrons created only on virtue of nuclear energy, China (and India soon, too) brings two or three new coal-fired power plants online every month.
*_TRUST !!_*
The Chinese communists encourage the “green energy transition” to cripple our industrial capacity, while they themselves continue to increase their fossil fueled industrial capacity to take over. Their goal is to be the sole source of manufactured goods for the entire world, which is to say, they wish to rule the world.
Are you ready to move your entire family because of flooding?
Climate change isn’t cost free.
I am 49. I remember when I was in grade 7, that was the beginning of the fear of sea level rise. by 2000 we were going to be all living inland, I lived in the Fraser River Delta. Guess what.. there are still people living in the Delta
People living in the Arctic have already had to move their homes as the permafrost melts out from under them…
@@allangibson8494 You do know the permafrost line has been moving north (in a general sense) since the end of the last Ice Age and in a more specific sense since the end of the Little Ice Age in the mid 1800s, right?
@@kirklaird5020 And most cities were built on a land level that was just above sea level in the last two centuries.
Rising sea levels are an infrastructure problem that needs addressing.
@@allangibson8494 Things change. Always have. Always will.
@@kirklaird5020 Why are the Republicans banning discussion and planning for sea level change?
So why is the sea level NOT rising? Because in the winter it snows again.
Compression of the ocean floor but think about the consequences of that volcanic eruption
Not only does it snow, it snows in Greenland MORE in winter than it melts in summer. The process of calving is not only from "lubricating rivers", but from the Billion tons of New snow every year.
@@LifeMyWay007 Yeah! That's what I'm talking about.
'The number one reason we are here is to make sure we use all the grant money we received, which in turn enhances our chances at receiving future grants. What? Oh, ice or sea levels or something.'
good documentary, but comments about lubrication or hydroplaning of the glacier on water are completely wrong. the water is under pressure at depth (rho*g*h) and decreases effective stress - also bouncy is in play for parts effectively floating on the melt water. the shear strength of meltwater, as a newtonian fluid, at the base of the glacier is zero. thus lubrication or hydroplaning are non existent
So, camping out in Greenland on NASA's mighty nickle...that about it? By the way, shouldn't The Danes be paying for this? Afterall, it is their island and its famously not for sale.
It seems to me that the Himalayan and Andean ice fields contribute more than Antarctica does. based on river out flows.
Kind of logical... except that Antarctica receives relatively little annual precipitation compared to the ice fields you mention. So outflow and inflow need to be kept in perspective before making that conclusion.
The Himalayas and Andes ice fields have basically vanished over the last millennium…

thank you
People should not advise when they know nothing
Take some footage in winter when it is -60 deg and bones frozen; then we can talk about climate change.
Yes, if there’s still seasons, there can’t possibly be long-term climate change. Try buying flood insurance in Miami, bro.
That's called weather. We're all talking about climate. Catch up.
Man made climate change is not a real thing. Guy in video is a Muppet.
You have your head in the sand! Wake up!
Could you be any stupider, I think not.
Want to end quote global warming turn of the power and go back to living life instead of feeding these people researching everything. Ya that harsh to accept but it would slow your concerns of quote global warming!
All thanks to Joe Biden 😅
@@Iwishiwasanoscarmeyerweinerfool
How so?
@@FDJT-47 Biden causes more flying around of jets for purposes of bombing children. This causes more GHG emission. This causes global overheating.
Pity he does not know it. Or does not know anything.
I'm surprised they didn't know snow melts during the summer they act shocked..it's obviously summer while filming this due to what they are wearing.
This is a breathtakingly obtuse comment.
Literally no sea level rise the past 500 years.
Perhaps, since we don't have tide gauge data that goes back that far. But according to tide gauge data that goes back about 200 years, sea level rise has been a pretty consistent 1.8 mm/yr since the mid - 1800s (world wide average along the coasts).
Lol, a whole video on bs fear mongering. Nice work!
Go drive your truck, scientists are at work and they don’t expect you to understand.
