For five months in 2015, a team of researchers drifted with polar ice, their ship tethered to an ice floe as they collected data to help them better understand how the loss of sea ice will affect the planet. The air above the Arctic Ocean has warmed on average about 5°F in the past century—more than twice the global average—and sea ice covers less and less of it. Most researchers study the ice during the summer. This team, battling bone-chilling cold, tracked it from when it formed in winter until it started melting in spring. And occasionally found time to kick a soccer ball around the floe. ➡ Subscribe: http://bit.ly/NatGeoSubscribe About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

VIDEO CREDIT: NOAA Since the 1980s, the amount of perennial ice in the Arctic has declined. This animation tracks the relative amount of ice of different ages from 1987 through early November 2015. The oldest ice is white; the youngest (seasonal) ice is dark blue. Key patterns are the export of ice from the Arctic through Fram Strait and the melting of old ice as it passes through the warm waters of the Beaufort Sea. In 1985, 20% of the Arctic ice pack was very old ice, but in March 2015, old ice only constituted 3% of the ice pack.

What Would Happen If All Ice On Earth Melted? ► Subscribe: https://goo.gl/r5jd1F Many people have wondered what would happen if all the glacial ice on the planet melted. Some believe that it would be a water world with no land in sight, while others think that could never happen. But the Earth is changing in more ways than you might think on its own. Many might wonder how much of the Earth’s current global warming trend is affected by humans. Regardless of who is to blame, whether the planet is just going through a natural phase in its evolution, or if we are responsible, the evidence shows that the planet is getting warmer and warmer every year. But just how much of the planet could end up covered in water if all the glacial ice melted? The Arctic isn’t the same as it was today as it was, say… 100 years ago. Temperatures there have been rising at twice the normal rate which has been sparking some very alarming changes unlike anything seen in recorded history. 87% OF Antarctica Peninsula Glaciers have melted since 1945. Now the regions sea ice is declining by 13% percent each decade. Scientific predictions that foresaw an ice-free Arctic Ocean during the summer between 2040 and 2050 may come to pass even sooner than we thought. A lot of people will think ‘well that’s no big deal… just get everyone to move to higher ground’. Sounds like a simple solution. However, aside from the fact that billions of people would be displaced, there would be more to worry about now that all the Arctic ice has melted. What is not commonly known is that the Earths’ poles not only get less direct sunlight than lower latitudes, but the sea ice is white, and therefore reflects most of the sunlight that hits it back out into space. That reflectivity called ‘albedo’ helps keep the poles cold and limits the heat absorption from the Sun. But that’s not all. Scientists have known for a long time that the Arctic tundra and marine sediments contain large frozen deposits of methane gas which, if released into the atmosphere, will increase greenhouse gases. So as the Arctic Sea ice melts, this source of methane will increase. Think runaway greenhouse effect which likely helped destroy the atmosphere on Mars along with the solar winds that stripped the planet of its atmosphere. But that’s not all. During this time there could be massive Earthquakes if the ice melted fast enough. One of the more uncommonly known things is that all that ice has some serious weight and suppression to it, and it has been holding down the Earth, and global warming has already bled the frigid continent of about 2.7 trillion tons of ice with over half those losses occurring in the last 5 years. Most climate scientists agree the main cause of the current global warming trend is human expansion of the greenhouse effect… warming that results when the atmosphere traps heat radiating from Earth toward space. Some of the things you can do are to buy anything reusable and be conscious of garbage and waste and try to recycle everything. Saving gas by walking more or taking the bus can help, as well as planting trees. But it takes more than just a handful of people to make a change, it takes everyone to make an impact. Perhaps humanity will embrace this global threat on our planet and governments will act fast enough to possibly reverse the damage. And for those people who procrastinate, the time for action is now…because we just may have an ally in our own Sun… We hope you enjoyed the video. Do you have an idea on how we could stop global warming? Let us know in the comments.

[nature documentary] It covers about 98% of the Antarctic continent and is the largest single mass of ice on Earth. It covers an area of almost 14 million square km (5.4 million sq. miles) and contains 26.5 million cubic km of ice (6.36 million cubic miles). That is, approximately 61 percent of all fresh water on the Earth is held in the Antarctic ice sheet, an amount equivalent to about 70 m of water in the world's oceans. In East Antarctica, the ice sheet rests on a major land mass, but in West Antarctica the bed can extend to more than 2,500 m below sea level. Much of the land in this area would be seabed if the ice sheet were not there. [nature documentary] National Geographic - Under the Antarctic Ice - Nature Documentary.

[nature documentary] --------------------------- The Universe (Wikipedia) The Universe is all of time and space and its contents. The Universe includes planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter at the present time. The size of the whole Universe is not known and may be infinite. Observations and the development of physical theories have led to inferences about the composition and evolution of the Universe. Throughout recorded history, cosmologies and cosmogonies, including scientific models, have been proposed to explain observations of the Universe. The earliest quantitative geocentric models were developed by ancient Greek philosophers and Indian philosophers. Over the centuries, more precise astronomical observations led to Nicolaus Copernicus's heliocentric model of the Solar System and Johannes Kepler's improvement on that model with elliptical orbits, which was eventually explained by Isaac Newton's theory of gravity. Further observational improvements led to the realization that the Solar System is located in a galaxy composed of billions of stars, the Milky Way. It was subsequently discovered that our galaxy is just one of many. On the largest scales, it is assumed that the distribution of galaxies is uniform and the same in all directions, meaning that the Universe has neither an edge nor a center. Observations of the distribution of these galaxies and their spectral lines have led to many of the theories of modern physical cosmology. The discovery in the early 20th century that galaxies are systematically redshifted suggested that the Universe is expanding, and the discovery of the cosmic microwave background radiation suggested that the Universe had a beginning.Finally, observations in the late 1990s indicated the rate of the expansion of the Universe is increasing indicating that the majority of energy is most likely in an unknown form called dark energy. The majority of mass in the universe also appears to exist in an unknown form, called dark matter. [nature documentary] ----------------------------- Note: Video not belong me.

Developed by Aker Arctic, the icebreaking rescue vessel Baltika is the first ship ever built with an asymmetric hull that allows her to break ice not only ahead and astern, but also sideways. In this way, the relatively small oblique icebreaker is capable of opening a wide channel in ice. Completed in 2014, the new icebreaker was scheduled to undergo full scale ice trials this winter in order to confirm the vessel´s performance. Baltika departed from Murmansk on 20 March 2015 with the Aker Arctic team on board and sailed around the northern tip of Novaya Zemlya and across the Kara Sea to the Gulf of Ob, close to the Sabetta terminal area, to carry out the ice trials. The testing program consisted of performance tests in two distinct ice thicknesses in ahead and astern directions as well as in the oblique mode. Various operational tests were also carried out in order to determine the maneuverability and operational capability of the vessel. The thickness and strength of the ice was measured in the areas where tests were carried out. An automatic measurement system was set up to record ice loads on the ship’s hull through the whole three-week voyage which concluded in Murmansk on 10 April 2015. Although the ice conditions in the area were on the upper end of the vessel’s designed icebreaking capability and the ice in the Gulf of Ob was considerably stronger than typical sea ice, Baltika exceeded expectations and the required performance targets were passed with a clear margin. The vessel could break 1.2-metre level ice in continuous motion when proceeding bow first and could achieve a speed exceeding 3 knots in astern direction. The oblique mode, which had never been tested before in real life, also worked extremely well and the vessel fulfilled all the design requirements. During operational tests, Baltika also demonstrated excellent maneuverability and rubble clearing capability in the port of Sabetta as well as ability to penetrate heavy compressive ice ridges in the Kara Sea without ramming. According to Project Manager Mika Hovilainen who was on board the vessel during the ice trials, “Baltika’s voyage to the Gulf of Ob proves the exceptional operational capability of the oblique icebreaker concept in very difficult ice conditions. The vessel could operate in ice conditions that exceeded the design criteria used as the basis of the vessel concept. Baltika could carry out the same operations as conventional icebreakers with just half of the propulsion power as well as perform maneuvers which are not possible for any other vessel currently in service.” Baltika (IMO number 9649237) was built by Arctech Helsinki Shipyard (Helsinki, Finland) in co-operation with Shipyard Yantar JSC (Kaliningrad, Russia) based on Aker Arctic’s oblique icebreaker design , Aker ARC 100. The vessel is 76.4 metres long and has a beam of 20.5 metres, and has a diesel-electric power plant consisting of three Wärtsilä 9L26 generating sets with a combined output of 9 MW. Baltika is propelled by three 2.5 MW Steerprop azimuth thrusters, two in the stern and one in the bow of the vessel. The dynamic positioning system, which also includes the oblique icebreaking mode, has been developed by Navis Engineering. The vessel is classified by the Russian Maritime Register of Shipping and its ice class is Icebreaker6. In addition to icebreaking duties, the vessel is also fitted with a built-in oil recovery system. Baltika is owned by the Federal Agency for Maritime and River Transport of Russia (Rosmorrechflot) and operated by the Russian Marine Emergency Rescue Service (FGI Gosmorspassluzhba). * * * Music by zero-project (www.zero-project.gr); used under Creative Commons Attribution (CC BY) 3.0 Unported License.

But when an Antarctic ice shelf the size of Manhattan collapsed in less than a month in 2002, it shocked scientists and raised the alarming possibility that Antarctica may be headed for a meltdown. Even a 10 percent loss of Antarctica's ice would cause catastrophic flooding of coastal cities unlike any seen before in human history. What are the chances of a widespread melt? "Secrets Beneath the Ice" explores whether Antarctica's climate past can offer clues to what may happen. NOVA follows a state-of-the-art expedition that is drilling three-quarters of a mile into the Antarctic seafloor. The drill is recovering rock cores that reveal intimate details of climate and fauna from a time in the distant past when the Earth was just a few degrees warmer than it is today.

Ph.D. student researcher Melinda Webster and colleagues report decreasing snow depth on Arctic sea ice, especially in the Beaufort and Chukchi seas. Their findings are based on airborne and in situ measurements, plus historical data from the Soviet drifting ice stations. Snow has key roles in the growth and decay of Arctic sea ice each year. APL-UW research suggests that it is delayed freeze up in the fall that is contributing to the decreasing snow accumulations. www.apl.uw.edu/SnowDepth

The FRAM-2014/15 expedition arrived in Longyearbyen on August 22nd 2015 with the hovercraft Sabvabaa after drifting across the inaccessible Arctic Ocean during one year. Prof. Yngve Kristoffersen and Audun Tholfsen have during the FRAM-2014/15 ice drift station has made unique geological, sea ice, ocean and atmospheric measurements from the inaccessible Arctic Ocean during all four seasons. The hovercraft and the ice drift station were deployed off the East Siberian coast by the German icebreaker Polarstern on 30. August 2014. The station has drifted 1900 kilometres across the Arctic Ocean until it ended in the Fram Strait one year later. On 18th August the ice drift station was recovered by the sealer Havsel and Sabvabaa was escorted back to Longyearbyen. This completes the exceptional Norwegian FRAM-2014/15 ice drift station hosted by the Nansen Environmental and Remote Sensing Center in Bergen, Norway.
The Arctic Ocean is virtually surrounded by land. The blanket of sea ice that forms there during the winter isn't completely free to drift away into warmer, southern waters. Because of that geography, it's common for sea ice to linger for many years at high latitudes, growing thicker and stronger, which makes it more likely to survive the summer melt. Or at least, it used to be common. The animation above shows how dramatically the amount of multi-year ice (ice that has survived at least one summer melt season) in the Arctic has decreased over the past two decades. Based on satellite tracking of ice parcels over time, the maps show the estimated age of sea ice once a week from January 1987 through mid-summer 2011. Ice age increases from darkest blue (1 year old) to white (9 or more years old). At the outermost edges of the ocean basin, the ice is seasonal: it forms every winter and melts every summer. Off the northeast coast of Greenland, a river of old ice continually flows out of the Arctic through the Fram Strait into warmer waters. Natural climate patterns accelerate the loss in some years and slow it down in others. Historically, that ice river was the major route by which the Arctic lost its very old ice. The export was balanced by ocean currents and wind patterns on the other side of the Arctic. Young sea ice gets caught up in the giant loop current called the Beaufort Gyre. The ice could remain in the gyre for years, circling around and around the central Arctic through the Beaufort and Chuchki Seas, growing thicker. The Beaufort Gyre was an incubator for growing multi-year ice. Since the late 1990s, however, the ice traveling through the southern part of the gyre rarely survives the summer melt. In other words, sea ice gets far less time in the incubator. In the mid-1980s, roughly 75 percent of the Arctic ice pack at the yearly maximum in March had survived at least one summer melt season; today only 45 percent has. Since the record low sea ice extent that occurred in summer 2007, no very old ice (9 or more years old) is left in the central Arctic basin. Only a thin ribbon remains tucked up against the islands of the Canadian Arctic. The loss of the multi-year ice is both a result of climate change and, ultimately, an accelerator of it. The less old ice there is in the ice pack, the more easily the ice melts in the summer. The more ice that melts, the more of the ocean that's exposed to the 24-hour summer Sun. Bright white ice reflects incoming sunlight, but dark ocean water absorbs it, heating the ocean and accelerating warming. credit: James Maslanik, Ned Gardiner, Hunter Allen, Richard Rivera, Rebecca Lindsey source: http://www.climatewatch.noaa.gov/video/2011/old-ice-becoming-rare-in-arctic

FLYING OVER ARCTIC SEA ICE | Stunning NASA Footage - From the Cockpit: The Best of IceBridge Arctic 2013 - The views from the cockpit of NASA's P-3B aircraft on an Operation IceBridge campaign are truly stunning. The mission doesn't travel to both ends of the Earth for the scenery of course -- the airborne mission is there to collect radar, laser altimetry, and other data on the changing ice sheets, glaciers, and sea ice of the Arctic and Antarctic. But for those of us who aren't polar pilots, here's a selection of some of the best footage from the forward and nadir cameras mounted to the aircraft taken during IceBridge's spring deployment over Greenland and the Arctic Ocean. - SUBSCRIBE to Bright Enlightenment http://www.youtube.com/BrightEnlightenment - On FACEBOOK: http://www.Facebook.com/BrightEnlightenment - Visit our WEBSITE: http://www.BrightEnlightenment.com -TWITTER: https://twitter.com/BrightEnlight - GOOGLE+ https://plus.google.com/u/1/105692605238227581556/ Credit: NASA's Goddard Space Flight Center #NASA #documentary #flying #Greenland #SeaIce #ClimateChange #GlobalWarming #film #BrightEnlightenment

Global sea ice levels, Arctic and Antarctic, were at their lowest point in the satellite record on 13 February 2017. Antarctic Sea Ice: Antarctic maximum - 31 August 2016, Antarctic minimum 3 March 2017 (2.11 million square kilometers) Arctic Sea Ice: Arctic minimum 10 September 2016, Arctic maximum 7 March 2017 (14.42 million square kilometers) On 13 February 2017, Global sea ice levels, the combined Arctic and Antarctic sea ice, were at their lowest point since satellites began to continuously measure sea ice in 1979. Total polar sea ice covered 6.26 million square miles (16.21 million square kilometers), which is 790,000 square miles (2 million square kilometers) less than the average global minimum extent for 1981-2010.

This visualization shows the seasonal variability of the weekly sea ice age between 1984 and 2016, growing in the Arctic winter and melting in the summer. Changes from year to year are also evident. Ice age is depicted in different colors. Younger sea ice, or first-year ice, is shown in a dark shade of blue while the ice that is four years old or older is shown as white. A color scale identifies the age of the intermediary years. One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. Perennial sea ice, also known as multi-year ice, is the portion of the sea ice that survives the summer melt season. Perennial ice may have a life-span of nine years or more and represents the thickest component of the sea ice; perennial ice can grow up to four meters thick. By contrast, first year ice that grows during a single winter is generally at most two meters thick. A graph in the lower, right corner the quantifies the change over time by showing the area in millions of square kilometers covered by each age category of perennial sea ice. This graph also includes a memory bar - the green line that here represents the current maximum value seen thus far in the visualization for the particular week displayed. For example, when showing the first week in September, the memory bar will show the maximum value seen for all prior years' first week of September since the beginning of the visualization (January 1, 1984). A graph in the lower, left corner the quantifies the change over time by showing each age category of sea ice as a percent of total ice cover in the Arctic Ocean. The lavender outline on the map indicates the spatial region covered by the Arctic Ocean and thus included in the graph.

Here's another stab at making videos to accompany the ASI 2013 updates on the Arctic Sea Ice Blog, in this case ASI 2013 update 2: http://neven1.typepad.com/blog/2013/06/asi-2013-update-2-shaken-and-stirred.html To cut down on size (faster upload) I've converted the file from 720p to 480p. The quality is a bit inferior, but IMO everything is clear enough. Let me know what you think about that, and also if you'd like to see other things improved. I will add other stuff, as soon as I'm convinced that this has added value.

For the next two weeks, we will be exploring the land of the polar bears with the Young Explorers. I'm very excited about this expedition but one thing bothers me. Will we see polar bears again? Did you know a polar bear can swim 100km or more without a break. BUT, the ice has moved 150km away from land today. The polar bears drown -- not only because of the greater distance but also because the waves that form due to the lack of sea ice. *shot on a GoPro !! Mike Horn on passing the Ballot Strait in July 2011: "The Ballot Strait lived up to its reputation as a dangerous passage. Strong currents, pack ice and very narrow waterway makes it a dangerous, tight squeeze! As we sailed into the strait it was more or less clear of ice. Twenty minutes later, we were tossed about like a cocktail in a blender. Pack ice all around us was pushing us towards the side. I gave the oder to open the genoa sail and slowly Pangaea started edging foreward...... We made it through, and saw our first polar bear on this trip." The 9th of 12 expeditions slated for Mike Horn's vessel, Pangaea, scheduled from 2008-2012 is destined for the Canadian territory of Nunavut. 'Nunavut' in the Inuit language means "our land". The territory includes part of the mainland and most of the Arctic Archipelago. It is the largest territory in Canada and accounts for 1/5 of the country!

The Sea of Okhotsk has long been the southernmost spot in the Northern Hemisphere where polar sea ice is found. After spreading southward out of the Arctic each winter and along the eastern edge of Sakhalin Island, the ice typically arrives in Hokkaido in mid to late January. The best time to see it is the latter half of February but it stays until late March or early April. However, over the past twenty years the drift ice has been slowly diminishing. Some say this is the result of global warming. The people of Abashiri have come together to take action. To read more about this http://ourworld.unu.edu/en/tourism-meltdown

This video is about the TOPtoTOP Expedition, trapped in the Pack Ice in the Arctic near the East Greenland Coast in July 2017 for 16 hours. We were 12 people. Sabine is expecting our next child on the 21st of August: We were trapped for 16 hours in the Arctic pack ice on our attempt to make landfall close to Turner Island, where the Inuits have found a hot spring. Unfortunately, there were too many clouds to define the exact density of pack ice from the sat picture. The ice chart was about one week old and underestimated the pack ice. We could see a stretch of open water close to shore on the sat pic that leads finally to the settlement of Ittoqqotoormiit, but there was no way to pass the heavy pack. It was time-consuming and not easy to find a way out in the sometimes dense fog, that is created by the cold ice. We used all our senses and suddenly heard some surf, expecting it from the swell that crashes against the outer line of the pack. Like this, we had an idea about the shortest distance out of the pack and in which direction to navigate to get free and back in open waters. The radar was useless because the flat pack didn't reflect the signal very well. Close to the limit of the pack ice the fog disappeared. From the top of the mast, we could see the open sea but at first no way through the last barrier of ice. It took Dario a while to study the ice to define the most promising channel to risk an attempt. All hands were on deck, outfitted with fenders and a stick to push the ice. Thanks to the great team work of each crew member, we managed to come through. We changed our strategy and sailed Northeast in open waters along the edge of the pack. From an older satellite picture, we hoped that we have a chance to get through this belt of ice coming more from the North into Scoresby Sound. Unfortunately, it did not get better and we changed course on 70 N / 20 W towards Grimsey Island at the Arctic Circle.

It is becoming common knowledge that we are rapidly heading to complete loss of Arctic sea-ice. Without a course reversal, one eventually gets where one is headed. What will the consequences be, to the Arctic and to the rest of the planet. Using my three cats as willing(?) helpers, I attempt to explain how the Beaufort Gyre and TransArctic Drift will reverse, monsoonal torrential rains will attack permafrost on land along Arctic coastlines, with severe increases in methane and carbon dioxide releases from this big thaw. Our world will rapidly change for the worse as Arctic feedbacks accelerate and the jet streams stall out. We will have to relearn how to grow food in new ways and regions as existing farmland becomes subject to droughts and/or switches to torrential rains. Buckle your seatbelts.
