Vanishing Arctic Sea-Ice: Expect the Unexpected...
By 2020 or earlier (maybe this year) humanity will experience our first Blue-Ocean event. Next to NO sea-ice cover on the vast Arctic Ocean in September. Within a few years NO ice in Aug/Sept/Oct; extended to July & Nov within a few more years. NO ice year round within a decade. As fast as sea-ice decline is (12%/decade), snow cover in spring is about twice as fast. Everything will change.

Sea ice - Video Learning - WizScience.com
"Sea ice" is frozen seawater. Because ice is less dense than water, it floats on the ocean's surface . Sea ice covers about 7% of the Earth’s surface and about 12% of the world’s oceans. In the North, it is found in the Arctic Ocean, in areas just below it and in other cold oceans, seas and gulfs; in the Antarctic, it occurs in various areas around Antarctica . Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent , a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. Sea ice does not simply grow and melt. During its lifespan, it is very dynamic. Due to the combined action of winds, currents and air temperature fluctuations, sea ice expanses typically undergo a significant amount of deformation. Sea ice is classified according to whether or not it is able to drift, and according to its age. Sea ice can be classified according to whether or not it is attached to the shoreline . If attached, it is called landfast ice, or more often, fast ice . Alternatively, and unlike fast ice, drift ice occurs further offshore in very wide areas, and encompasses ice that is free to move with currents and winds. The physical boundary between fast ice and drift ice is the "fast ice boundary". The drift ice zone may be further divided into a "shear zone", a "marginal ice zone" and a "central pack". Drift ice consists of "floes", individual pieces of sea ice 20 m or more across. There are names for various floe sizes: "small" – 20 m to 100 m; "medium" – 100 m to 500 m; "big" – 500 m to 2000 m; "vast" – 2 km to 10 km; and "giant" – more than 10 km. The term "pack ice" is used either as a synonym to "drift ice", or to designate drift ice zone in which the floes are densely packed. The overall sea ice cover is termed the "ice canopy" .

Sea level rise is so much more than melting ice
While researching climate change, we heard something confusing: the sea level in New York City is rising about one and a half times faster than the global average. We couldn’t figure out what that meant. Isn’t the sea level...flat? So we called up an expert and went down the rabbit hole. And, we did our best to visualize her truly bizarre answers with animations, dioramas, and a lot of melting ice.

Antarctica is losing ice at an accelerating rate. How much will sea levels rise?
The frozen continent of Antarctica contains the vast majority of all freshwater on Earth. Now that ice is melting at an accelerating rate, in part because of climate change. What does this transformation mean for coastal communities across the globe? William Brangham reports from Antarctica on the troubling trend of ice loss and how glaciers can serve as a climate record from the past.

WARNING! Polar Ice Caps Melting Rapidly | Ice Free Arctic By Summer 2017!
Since the year 2000 we have had 16 of the 17 warmest years ever recorded, with 2016 being the warmest yet. As march almost ends it becomes clear that the ice caps are not the same as they once used to be. They are shrinking dramatically fast and are not following a linear equation anymore, but rather an exponential one. It is predicted that on the current course we could have an ice free arctic by as soon as the summer of 2017, and 2020 at the LATEST. This is a very bad situation, as the polar caps act as the earth's air conditioners and help to keep the planet cool. Also underneath the frozen arctic lies a massive methane reserve, which if released by the melting permafrost will release enough methane into the atmosphere to kill all life on earth and render it inhospitable. Will the human race wake up to the imminent threat in time or will we continue to be blind and ignorant until it's too late? Music: www.purple-planet.com

Arctic Sea Ice Continues a Trend of Shrinking Maximum Extents
Arctic sea ice reached its annual maximum extent on March 17, according to analysis by NASA and the National Snow and Ice Data Center. The 2018 extent reached 5.59 million square miles, only about 23,000 square miles larger than the lowest maximum on record, in 2017. This continues a trend of shrinking sea ice, with the four lowest Arctic sea ice maximum extents on record in the last four years.

What Would Happen If All Ice On Earth Melted?
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.

Update from Antarctica: Sea Ice Breakout 2019
Watch how the 2m-thick sea ice broke out in front of McMurdo Station, Antarctica over the last few days (Feb. 3-4, 2019). With a strong south wind, the ice front receded stepwise around Hut Point Peninsula. The major disintegration events were extremely fast, 15-30 min. The summer sea ice breakout is a normal occurrence that happens in most years. But, it didn't occur last year. The timelapse video covers about ~24hrs, with images from McMurdo Station (USA) and Scott Base (New Zealand) webcams. There's now much more light at the MOO research site, and, owing to the open water overhead, we're now recording orca (killer whales) on our hydrophone.

Arctic Sea Ice Is the Thinnest and Youngest It's Been in 60 Years
Working from a combination of satellite records and declassified submarine sonar data, NASA scientists have constructed a 60-year record of Arctic sea ice thickness. Right now, Arctic sea ice is the youngest and thinnest its been since we started keeping records. More than 70 percent of Arctic sea ice is now seasonal, which means it grows in the winter and melts in the summer, but doesn't last from year to year. This seasonal ice melts faster and breaks up easier, making it much more susceptible to wind and atmospheric conditions.

Polar regions: Arctic sea-ice future, Antarctic ice-shelf stability, and glacial landforms (EGU17)
European Geosciences Union Media at General Assembly 25 April 2017. The polar regions, at the north and southern extremes of our planet, are some of the most unique and fragile areas on Earth. The Arctic is warming twice as fast as the global average, with drastic consequences for the sea-ice cover in the region, which hit its lowest annual extent on record in 2016. A talk at this press conference will look into what 2016 Arctic sea ice can tell us about future sea-ice conditions in the region. We will also hear about how future Arctic sea-ice cover will differ for 1.5 and 2°C, the two global warming limits in the Paris Agreement. Moving south, another presentation will look into the impact that warm winds (Foehn winds) are having on the weather, climate and ice shelves in Antarctica, specifically Larsen C. This ice shelf is located in the Antarctic Peninsula, the fastest warming region on Earth in the late 20th century, and is at risk of collapse. This press conference will end with the presentation of a new seabed map of the polar regions, an atlas of submarine glacial landforms with stunning images. Participants: Julienne Stroeve Senior Research Scientist, University of Colorado, National Snow and Ice Data Center, United States James Screen Senior Lecturer, Department of Mathematics, University of Exeter, United Kingdom Jenny Turton PhD Student, British Antarctic Survey and University of Leeds, United Kingdom Kelly Hogan Marine Geophysicist, British Antarctic Survey, United Kingdom http://client.cntv.at/egu2017/press-conference-4 http://egu2017.eu/webstreaming.html

Arctic Sea-Ice Collapse Accelerating. What Next?
As Arctic sea-ice plunges to record lows, many pundits are calling for a near-term Blue Ocean Event in which the entire Arctic Ocean is essentially devoid of ice. In this video analysis (and next), I chat time frames for increasing duration of the open ocean state, from 1 month to 3 to 5 and then to year-round. I emphasize the overlooked but equally important loss of terrestrial snow cover to make the Arctic a very dark and hot place. I discuss changes to jet streams, including a 17 degree latitude shift south in its center of rotation, and changes to weather drivers from jet-stream to monsoonal, even in the Arctic.

“Rising Seas: How Fast, How Far?” – the Earth101 lecture
Sea-level rise is one of the inevitable results of global warming, as warmer ocean waters expand and land ice is melting and adding water to the oceans. Observations show that the seas are indeed rising, and that the rise in the 20th Century is unique in the context of the previous millennia. However, more difficult to answer is the question of how fast and how far sea level will rise in the future. The billion-dollar-question is: How stable are the ice sheets on Greenland and Antarctica? Stefan Rahmstorf obtained his PhD in oceanography at Victoria University of Wellington in 1990. He has worked as a scientist at the New Zealand Oceanographic Institute, at the Institute of Marine Science in Kiel and since 1996 at the Potsdam Institute for Climate Impact Research. His work focuses on the role of the oceans in climate change. In 1999 Rahmstorf was awarded the $ 1 million Centennial Fellowship Award of the US-based James S. McDonnell foundation. Since 2000 he teaches Physics of the Oceans as a professor at Potsdam University. Rahmstorf served from 2004–2013 in the German Advisory Council on Global Change (WBGU) and was one of the lead authors of the 4th IPCC Assessment Report. Dr. Rahmstorf has published over 100 scientific papers (30 in leading journals such as Nature, Science and PNAS) and co-authored four books. Available in English are Our Threatened Oceans (2009, with Katherine Richardson) and The Climate Crisis (2010, with David Archer).

Does ice melt faster in fresh or salt water? (Ice Science Experiment for kids)
DOES ICE MELT FASTER IN FRESH OR SALT WATER? Experiment PROCEDURE: Put your favorite food coloring in a ice cube tray with water and freeze. Fill one transparent cups up with tap water, and the other with tap water and add salt. Observe the rate of melting of each ice cube. EXPLANATION: I love the results of this experiment as it really surprise me. When I put salt on a ice cube it melts the ice very fast and when I saw this I could not believe it. The ice cube in the salt water melts much slower then the one in the fresh water. In the salt water the colored water from the melted ice cube forms a distinct layer that floats on top of the salt water. In the fresh water, the melted water sinks to the bottom and is evenly spread out. These observations can be interpreted by comparing the density of fresh water and salt water. When the ice melts, the water that results in very cold. It is more dense than the warmer tap water in the cup, and will thus sink. As we see on the left side. As the colder water sinks, it displaces and pushes up the warmer tap water from the bottom. As this warmer water comes into contact with the ice cube, it hastens its rate of melting. A convection current has been set up, where the colder water sinks and the warmer water is pushed up. Convection is the transfer of heat by the movement of fluids. In the cup of salt water, the cold water that results from the melting of the ice cube is less dense than the salt water, so it floats on top. There are no convection currents occurring here. Since the ice cube is constantly in contact with the very cold water, which prevents it from contacting the warmer water below, it takes a longer time to melt. This happens in the oceans where Icebergs last much longer in salt water then they do in fresh water. The melted ice from an iceberg will float on top of the salt water in the ocean, but will sink in fresh water. Ice cubes will cool a diet drink much faster then they will a sugared drink for this same reason.

NASA | Arctic Sea Ice Reaches 2014 Minimum Extent
Sea ice acts as an air conditioner for the planet, reflecting energy from the sun. On September 17, the Arctic sea ice reached its minimum extent for 2014. At 1.94 million square miles (5.02 million square kilometers), it’s the sixth lowest extent of the satellite record. With warmer temperatures and thinner, less resilient ice, the Arctic sea ice is on a downward trend.

Stable Antarctic Ice Is Suddenly Melting Fast
Sea levels worldwide will rise higher than anticipated, thanks to a new once-stable region of Antarctica that is suddenly melting, and at a fast rate. Analysis of satellite data shows that although the massive ice sheet on the Southern Antarctic Peninsula, made up of multiple glaciers, was rock solid from 2000 to 2009, since then it has begun to melt rapidly. The glaciers, stretching along 750 kilometers of coastline, are shedding 60 cubic kilometers of ice into the ocean each year—about 70,000 Empire State Buildings of ice annually. Bert Wouters, a fellow at the University of Bristol, who led the analysis, published in the May 22 issue of Science said, The onset of such rapid loss “came as a surprise to us." In just a few years, he says, the dynamics of the region “completely shifted." http://www.scientificamerican.com/article/stable-antarctic-ice-is-suddenly-melting-fast/ http://www.wochit.com This video was produced by Wochit using http://wochit.com

Antarctic Ice Double-Whammy: Sea Level Rise—Interview w/Dr. Richard Levy—Radio Ecoshock 2019-01-31
When it comes to sea level rising by feet or meters, the biggest fear is melting mountains of ice piled up on Antarctica. Recently NASA scientist Eric Rignot told us those glaciers are melting six times faster now than in the 1950’s. In another just-published paper, scientists discovered the marriage of two forces making that happen. This could determine the future map of the world, as disastrous sea flooding invades farmlands, cities, and whole nations. The science is challenging. It involves a 34 million year history of Antarctic ice, tiny single-celled animals, carbon dioxide, and the astronomical place of Earth in space. All of that. Fortunately we have lead author Dr. Richard Levy here to help. Dr. Levy is a Paleoclimate Scientist and Programme Leader at New Zealand’s GNS Science, a government Crown Corporation. Levy is a veteran of scientific expeditions to Antarctica, with many papers about the coldest continent on Earth. He is the co-author of “Antarctic ice-sheet sensitivity to obliquity forcing enhanced through ocean connections” as published in Nature Geoscience 2019.

Learn more at https://stopfossilfuels.org SHOW NOTES Normally I recommend listeners go straight to the science published in the journals. In this case, I think you should start with a great summary published at phys.org: “Antarctic ice sheet could suffer a one-two climate punch”. Without understanding scientific terms like “obliquity”, you might miss the importance of Levy’s work without this article by Devitt, and my Radio Ecoshock interview. To understand the underlying astronomical cause of changes in Antarctic ice, we need to grasp Milankovitch cycles: "the collective effects of changes in the Earth’s movements on its climate over thousands of years. The term is named for Serbian geophysicist and astronomer Milutin Milankovic. In the 1920s, he hypothesized that variations in eccentricity, axial tilt, and precession of the Earth’s orbit resulted in cyclical variation in the solar radiation reaching the Earth, and that this orbital forcing strongly influenced climatic patterns on Earth." OBLIQUITY OR AXIAL TILT “The angle of the Earth’s axial tilt with respect to the orbital plane (the obliquity of the ecliptic) varies between 22.1 and 24.5°, over a cycle of about 41,000 years. The current tilt is 23.44°, halfway between its extreme values. The tilt last reached its maximum in 8,700 BCE. It is now in the decreasing phase of its cycle, and will reach its minimum around the year 11,800 CE. Increased tilt increases the amplitude of the seasonal cycle in insolation, providing more solar radiation in each hemisphere’s summer and less in winter. However, these effects are not uniform everywhere on the Earth’s surface. Increased tilt increases the total annual solar radiation at higher latitudes, and decreases the total closer to the equator. The current trend of decreasing tilt, by itself, will promote milder seasons (warmer winters and colder summers), as well as an overall cooling trend. Because most of the planet’s snow and ice lies at high latitude, decreasing tilt may encourage the onset of an ice age for two reasons: There is less overall summer insolation, and also less insolation at higher latitudes, which melts less of the previous winter’s snow and ice.” ANTARCTIC SEA ICE MAY DETERMINE THE FATE OF COASTAL CITIES AROUND THE GLOBE Richard Levy tell us: “Antarctica turns out to be way more sensitive to climate change than was previously thought.” And the key, key factor is the state of Antarctic sea ice. That southern pole sea ice was staying strong, even growing a little since 2014. Since then, it has begun a decline every year, likely including this one. The sea ice serves as “buttress”, a block that slows down the flow of Antarctic glaciers into the ocean. When sea ice melts it is like an ice-cube in your glass because sea ice does not raise sea level. But ice from the big glaciers can put sea levels up at least 20 meters, or 75 feet higher. Imagine that. Richard Levy says their data suggests that in previous times, when the world was 1.5 degrees warmer (than pre-industrial) sea levels were 6 to 9 meters higher than they are now. We may already have a long way to go, as the seas relentlessly rise over the next centuries. We know from the study led by Eric Rignot that Antarctica is already losing ice mass, at a rate 6 times greater than in the 1950’s. Antarctica is melting. It will melt even faster as the sea ice there continues to shrink. This paper provides a double-checked visual graphic of the last 34 million years of the Antarctic ice sheet. That time map can be used by a lot of other scientists, and amateur climate bloggers like myself.

The New Record Low Arctic Sea Ice and Our Weather
Arctic sea ice decline has long been projected to occur. 2018 and 2017 are the two lowest winter time Arctic sea ice records observed. Disappearing sea ice and moisture transport into the Arctic are believed to cause something called Arctic amplification, which in turn has been linked to two effects (weaker westerly winds, and intensified ridges), causing warm air to flow into the Arctic and colder air intrusion in lower latitudes, associated with slow moving weather systems.
