Melting Giants: Climate Change's Impact on East Antarctica, Arctic Sea Ice, Greenland, West Antarctic Ice Sheets, and Alpine Glaciers

Marine Ice Sheet Instability in East Antarctica: East Antarctica is the largest ice sheet on Earth and contains enough ice to raise sea levels by over 50 meters. Recent research has suggested that some regions of the East Antarctic ice sheet may be more vulnerable to melting than previously thought. The tipping point is uncertain, but it is thought to be around 2 to 4 degrees Celsius above pre-industrial levels. Arctic Sea Ice: As the Arctic Sea ice melts, the Arctic Ocean absorbs more solar radiation, which amplifies warming. The tipping point is estimated to be around 4 to 6 degrees Celsius above pre-industrial levels.  Greenland and West Antarctic Ice Sheets: If the Greenland ice sheet melts, sea levels could rise by 7 meters. If the West Antarctic ice sheet melts, sea levels could rise by 5 meters. The tipping point for these ice sheets is uncertain, but estimates range from 1.5 to 4 degrees Celsius above pre-industrial levels. Alpine Glaciers: Alpine glaciers are found in moun...

UN patron of the oceans Lewis Pugh has completed what's been described as the 'coldest swim on earth' in Greenland to highlight the speed at which polar ice is melting. He completed the first multi-day polar swim ever at Ilulissat Icefjord, which is fed by the world’s fastest-moving glacier. His stark message, ahead of next month's COP26, is that without polar ice, there is no life on earth. He is right, but some people just ignore facts. Too bad, because we all will suffer even the rich.

5 min. video. A huge Antarctic glacier is ripping itself apart and the 'Doomsday Glacier' could be next | ABC News

Image
New satellite data show the Pine Island Glacier, one of Antarctica's largest glaciers, "ripping itself apart". The unexpected loss of the ice shelf comes on top of a series of huge calving events in the last 12 months that have seen massive icebergs split away from the southern continent. Western Antarctica is particularly vulnerable because of one fatal flaw and right next door to the Pine Island Glacier is the Thwaites Glacier – or what scientists call the Doomsday Glacier. If Thwaites falls apart it could unleash the collapse of the entire ice sheet on the western half of the continent. A stat we are missing is a map showing the location of the grounding line year by year. I understood that this is detectable by looking at the surface contours of the ice. It should include the depth of the sea bottom for each contour line.

Image
GREENLAND — In recent years, scientists have used advanced technologies like airborne radar to see how Greenland looks under its three-kilometer deep ice sheet. They found that the world’s largest island is hiding quite a few fascinating surprises. Here are the details: Live Science reports that recent scientific studies have found a number of fascinating phenomena hidden under the three-kilometer deep ice sheet that covers Greenland. One of these hidden phenomena is a huge canyon that’s almost as big as the Grand Canyon. Stretching for 740 kilometers, this hidden canyon is up to 10 kilometers wide and up to 800 meters deep in places. Another study found a massive plain in the middle of Greenland that lies below sea level. This strange depression is probably caused by the weight of the ice sheet, and it’s surrounded by a ring of hidden mountain ranges.

5 min. Earth Itself Warming 'Doomsday Glacier' on Top of Climate Change, Causing Massive Melting

Image
Climate change isn’t the only factor melting the Thwaites Glacier, according to a new study from the Earth Communications and Environment journal. Rather, the Earth itself may also be warming the massive block of Antarctic ice, which is colloquially known as the "Doomsday Glacier." According to the study, the crust beneath west Antarctica is between 10 to 15 miles or 17 to 25 kilometers thick compared with around 25 miles or 40 kilometers in the East and this means that substantially more heat from below can access the West than can access the East. The researchers found that a geothermal heat flow of up to 150 milliwatts per square meter can occur beneath Thwaites Glacier, according to the study’s lead author.

Heatwaves are a natural phenomenon, but concurrent conditions can exacerbate their impacts. As Arctic sea ice continues to melt in a warming world, there is a ripple effect on the global climate. This woman is an icon. She's been saying this for so long. It's sad that it has taken us so long to listen There's no chance "elected" officials can move quick enough and as drastic as is needed. This world is a huge joke. Innocent people are victimized for the gain of others. The true criminals will never face justice in this life.

Anticyclone over Greenland still wreaking havoc on ice caps. Some scientists believe we could be close to the point of no return, as extreme rain on the highest point in Greenland causes severe ice melting. Normally it would snow at this altitude and location on Greenland. Rain has never been seen or recorded in human history. It comes only a matter of weeks after an extreme heatwave caused a historic ice melt in the region. Which is believed to cause ripple effects throughout the planet - namely rising sea levels, and the slowing of the Gulf Stream, which is likely to throw gasoline on an already worsening climate change problem

Massive ocean currents, such as the Gulf Stream, move heat from one part of the planet to the other. This process, in part, helps to give Western Europe its mild winter climate. But climate change is already having a visible effect on the world's temperatures and scientists are starting to build a clearer picture of what happens when certain climate components near their tipping point. Dr. Levke Caesar is part of an international group from the UK, Ireland and Germany who are collecting data about one of the largest ocean currents – known as the AMOC. Fellow mankind, are you listening.....?

10 min. video. Massive Melting Event Strikes Greenland Due to Heat Wave

Image
GREENLAND — A "massive melting event" has affected Greenland’s ice sheet during a heat wave that has brought temperatures more than twice as hot as seasonal averages, according to Danish researchers cited by Agence France Presse. Since Wednesday the ice sheet has melted by close to 8 billion metric tons a day, twice its normal average rate during summer, according to tracking site Polar Portal website, which is run by Danish researchers. While this loss of volume was not as extreme as the largest single-day melting event in 2019, the researchers say the area over which melting took place is actually larger than two years ago. Fossil burning is not slowing; it’s increasing. All the projections of recent years have proven to be massive underestimates. The human race is incapable of prolonging it’s “last best chance.” The near future prospects are simply terrible.

3 min. video. Heat Wave In Greenland Sees Record Amount Of Ice Melt

Image
An anticyclone over Greenland caused a heatwave, which in turn caused a record amount of ice to melt into the sea. For over three decades the huge ice caps - one of the world's largest sources of freshwater - have been melting at an alarming speed. And things are only getting worse... Many scientists already believe that Greenland has passed the tipping point, and is well on it's way to a complete meltdown - excuse the pun. This latest extreme melt could be the straw that broke the camel's back. Accelerating the demise of the picturesque, icy land mass, that may not exist in a decades time, and will likely cause sea levels to rise on a global scale, destroying billions of peoples lives, and swallowing up huge cities in the process.

The UN has named the month of June as ‘World Ocean's Month’ and so this video is titled Our Polar Oceans in Peril. The polar oceans are the Arctic and Southern/Antarctic oceans. This video was recorded on June 18th, 2021 and published on June 30th, 2021. Dr. Peter Carter, Paul Beckwith and Regina Valdez will discuss why the polar oceans play such a critical role in the climate system of our planet. They focus mainly on the Arctic ocean and various feedback mechanisms leading to further warming, sea level rise, and harm to the ecosystem. Further highlights include: - The reason we’ve enjoyed a relatively stable climate over the last 10,000 years allowing us to produce an abundance of food to support and build our civilization - Quantification of the Earth’s ice imbalance leading to a loss of 7.6 trillion tonnes of Arctic sea ice along with 0.9 trillion tonnes of Antarctic sea ice - The stunning fact that the heat being retained by the climate system has doubled over the last 14 ye...

Dr. Steve Zornetzer former NASA discusses the current state of arctic sea ice and the impacts on global warming. The sea level is rising simply by the fact that water expands the hotter it becomes. When the ocean's waters heat up this phenomenon adds to the overall height of the increase. "...if we could do that..." Translated means we can't and we won't. Tiny, floating glass beads harmless? Sure. What could go wrong? The expression "Grasping at straws." comes to mind....

12 min. video. Arctic Methane. Has 2020 triggered a tipping point?

Image
The summer of 2020 saw record breaking heatwaves across the Arctic region resulting in the lowest ever recorded October sea ice levels. Those persistently warm temperatures also caused the thawing of permafrost and sediment on the seabed allowing the release of very high concentrations of methane - in some cases up to 400 times normal levels. So, have we now reached the long anticipated tipping point? Never have such alarming news been delivered so calmly. I'm 63yrs old so I suspect I'll be dead before the worst effects are experienced, but the human race is pathetic. Faced with total disaster we're more concerned with losing " money" than our descendants.

This is a short lecture on how climate change is affecting Arctic and Boreal Ecosystems, and how the response of those ecosystems is starting to influence the global climate system. Reminds me of Walter Jen and his talks about soil and hydrology. The most important point you raised there was how not all models have the data or possibilities considered, I've long held the view that serious "super computer power" be tasked with the most comprehensive modelling to ensure we are getting the best possible predictions. If we have under stated serious climate shift then the consequences could be devastating if the rate of change is too great for our food agriculture systems. Imagine food and water shortages on a global scale just because we underestimated the size of the problem.

9 min. video. What's hidden under the Greenland ice sheet? | Kristin Poinar

The Greenland ice sheet is massive, mysterious -- and melting. Using advanced technology, scientists are revealing its secrets for the first time, and what they've found is amazing: hidden under the ice sheet is a vast aquifer that holds a Lake Tahoe-sized volume of water from the summer melt. Does this water stay there, or does it find its way out to the ocean and contribute to global sea level rise? Join glaciologist Kristin Poinar for a trip to this frozen, forgotten land to find out. "The aquifer water drives the crevasse all the way to the base of the ice sheet, a thousand meters below". "The Greenland ice sheet is huge, the size of Mexico. And it's ice from top to bottom is two miles thick". So...is the ice sheet thickness a thousand meters, or two miles??? BIG difference! (Unless the snow {aquifer} is over seven thousand feet.) A much simpler and more accurate method of determiming the amount of glacial loss is the hundreds of millions of years of...
