- Greenland, "Green Country" of the Vikings, carries a misleading name. In winter or summer, most of this autonomous region of Denmark, four times larger than France, is covered with a thick white layer that represents 10% of world’s ice. As temperatures rise, glaciers retreat; hundreds of gallons of melted ice flow out to the sea every day. This is a global concern, as the melting of Greenland ice is a key factor in understanding the rise of sea levels.

Beautiful footage🎉🎉
What an amazing place👍👍 awesome views👍👍 stay connected🌺🌺Greetings from Poland. Cold🥶🥶🥶🤣🤣😂
See Glacier Girl P-38 plane that landed on the ice in Greenland along with other out of fuel planes in 1942. It was dug up in 1992 from 82 meters of packed snow and ice. The other planes are still down there under even more ice and are slowly moving like glaciers do.
Ask if any icebreaker cruise ships made it to the North Pole this Summer. They never guarantee you will.
There is absolutely nothing anybody can do about sea level rise. It's a fact of life, and it's here to stay.
While these small changes may appear insignificant, they can indeed trigger major reconfigurations in key ecosystems, endangering the fragile equilibrium of life on a global scale. Moreover, due to human influence, these changes are occurring at a much higher speed than previous major shifts in the history of our planet. If you're interested in delving deeper into the key role of oceans in the preservation of life on Earth, this video may be useful: ua-cam.com/video/Vrj4X9C5C9s/v-deo.html
@@SLICE_Experts How does this refute my post? Rising sea levels at 3.4mm per year cannot possibly "trigger major reconfigurations in key ecosystems." Humans have been dealing with natural shore erosion since the beginning of time. Natural shore erosion has destroyed countless millions of structures. It has caused the collapse of entire cliffs. People live on the water's edge at their own peril. It's a choice billions have made and have no regrets. We adapt.
Your argument is also rather disingenuous. Humans have been directly involved in decimating ocean species for several hundred years. This is due to rising populations and has nothing to do with a warming planet. In fact, the destruction of all wildlife over the last 500 years has solely been caused by poaching and habitat destruction due to human encroachment. Warming isn't killing anything. Life flourishes under warming. The greatest diversity of life on this planet resides in the tropics, not Greenland.
@anthonymorris5084, let's start by facing the facts. The Sundarbans are already endangered due to rising sea levels, which introduce saltwater into freshwater habitats, disrupting a delicate equilibrium. As explained in the video I linked in my previous reply, the ocean absorbs significant quantities of CO2 released into the atmosphere. This is particularly concerning as it puts coral reefs, one of Earth's richest biomes, at risk. These are just two examples off the top of my head, but the list goes on. Both of these issues are directly linked to rising temperatures, for which humans bear responsibility.
What is disingenuous is your attempt to disregard these facts, and thereby ignore the responsibility we have in the ecological crisis we are currently experiencing. While a rising population does contribute to higher demands on our planet, it cannot be solely attributed to today's environmental problems. Your explanation falls short in providing a comprehensive understanding of the complex issues at hand. Life on Earth is interconnected; the tropics and the poles are more related than you might think!
@@SLICE_Experts Sorry, not buying it. You can drone on about sea level rise all day. Sea levels have been rising consistently for 10,000 years. There is nothing you can do to stop this phenomenon. You could end all fossil fuel production across the globe tonight at midnight, sea level rise is here to stay. Life flourished over this warming period of 10,000 years and humans didn't have an ounce of technology. Preventing sea level rise is delusional.
Environmentalists are of the mind that change always equals catastrophe. Ecosystems across the globe change quite dramatically and rapidly all the time. Life is simply not that fragile. I can assure you more wildlife habitat has been destroyed by human encroachment than sea level will ever destroy so again, your argument is disingenuous. In the 1800's there were 100,000 tigers roaming the wild. Today there are around 3,400. Salt water in the Sundarbans hasn't killed a single tiger. Humans decimated them through poaching and habitat destruction. We are paving the planet, saltwater intrusion is the least of our problems.
CO2 has gone from .03 to .04. Without scientific instruments nobody would even know. Over the last 800,000 years CO2 continuously bounced up and down from around 180ppm to 300ppm. Below 150 and all plant life begins to die. Fossil fuels may have actually saved all life on Earth. The average over the last 600 million years was around 3000ppm and life flourished during these periods.
Coral reefs are being destroyed by agricultural runoff and human interaction with the reefs. Coral migrates just like plants. Studies of the Great barrier reef show a recovery is underway. Sink a ship off of any coast and a reef will materialize.
Over population is at the foundation of almost every single threat to both humanity and nature. From resource depletion, deforestation, pollution, garbage, plant and animal habitat destruction, the decimation of our oceans, agricultural production and on and on. The climate movement doesn't care. You folks are the champions of hyperbole and scapegoating. You're not fixated on the actual problems, you're fixated on a narrative. If you truly cared about nature, you'd be promoting a reduction of family size across the world. Sorry for the length.
WHY? do they always go up the the Arctic in Summer? - They should go in January. My thoughts Anyway.
A lot of measuring equipment stays throughout the year.
People are not needed all the time.
More ice bergs means that ice is increasing on the glaciers and so increasing the flow of the glaciers down to the sea.
Although the presentation is valuable, it's also 10 years old going by the time-lapse camera date-stamps.
It would be interesting to see the melting for the fifty years prior to 1948 when the observations started, especially since temperatures in the early 20th century were similar to present day. It would also be interesting to see how much the glaciers grew during the 1960’s and 70’s.
Air temperatures have increased dramatically since 1980. The earth was slowly cooling at the beginning of the twentieth century in line with the Milankovich cycles of the last million years. Anthropogenic global warming is reversing that trend and driving temperatures higher.
According to their photos this glacier is not retreating ... PS/ What's become of the Extreme Ice Survey?
3.4mm isn't very much, however this figure isn't based upon the minuets that levels will change. Next year 3.4mm may become 1.5m.
The Greenland surface mass balance (SMB) increase for the year 2022-23 was a massive - and well above 1981-2010 average - 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Greenland has been cooling since 2012.
Uhm, No!
Still getting hotter.
Glaciers retreating.
More rain than snow.
No sea ice except the northern most areas.
@oneshothunter9877 Umm yes. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades in the Arctic, and May 2023 was the coldest on record there.
The Greenland surface mass balance (SMB) increase for the year 2022-23 was a massive - and well above 1981-2010 average - 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Greenland has been cooling since 2012. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking.
@oneshothunter9877 More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass (around 3 million gigatonnes). That's neglible. Come back in 20,000 years.
When folks ask why the ice capes are melting, their not. There never was a Ice breaker 150 years ago, now there are 1000's that never let the polar caps reharden. Think about it.
According to NASA sea levels are rising at 3.4mm per year. This is imperceptible without scientific instruments. Quick, walk, walk, walk for your lives.
Thé US needs to fortify their coastal and river cities and towns or none of their wars are going to save anyone or anything.
Just in case you didn't know. Did you know that glaciers have been melting and growing for thousands of years??
So, nothing new here , is there!
You missed the part where they said the speed of retreat has doubled?
That sounds pretty "new' to me.
@jimthain8777 double the speed of what, where, and when based on what?? Can you or anybody ie: reputable scientists tell us what the earth's mean temperature is supposed to be!!! Let's say, for 10 melinnia, either side of 2023. Come on now, there has to be a consensus on this!. Can any Mann answer?
@@jimthain8777 where you from? Im dutch while typing 2 meters below sea level 😏 you probably Amrikan colonist scared of karma glaciers and Russians
@@derekborkent2899 Your words come straight from Uranus.
@joejoe-vx4xs Typical reaction to throw insults when you haven't got an answer to a question. But that's naturally to be expected from dumb climate sheeples.
Why can't someone put people claiming climate change isn't real like Judith curry she still putting out books and videos saying it's not real and no one's debating her
😊
Because everyone knows she is bullsh...... anyways.
"Don't feed the troll" are the reason why.
😁
They don’t dare to debate her.
