Arctic Sea-Ice Collapse Accelerating. What Next?
 
15:01
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.

Zero Arctic Sea Ice Very Likely By 2020
 
14:59
There is a very high probability that the Arctic sea ice will essentially vanish by the end of summer melt in 2020 or earlier. The ice-free duration would likely be less than one-month in September for this first "blue-ocean" event. I discuss the stories in the observations leading me to this conclusion. If the ice goes, it will affect every human, plant and animal living on our planet. Please support my videos with a donation at http://paulbeckwith.net

Arctic Sea Ice is Disappearing at Alarming Rate
 
02:56
Arctic sea ice melt in the summer is normal but experts say it's thinner now, disappearing earlier and returning later in the fall. Since the first orbital images in 1979, sea ice coverage dropped an average of 34,000 square miles a year.

Arctic sea ice growing younger, thinner
 
01:20
(narrated version) Decades ago, the majority of the Arctic's winter ice pack was made up of thick, perennial ice. Today, very old ice is extremely rare. This animation tracks the relative amount of ice of different ages from 1990 through early November 2016. Seasonal ice is darkest blue. Ice that is 9 or more years old is white.

Arctic Sea Ice Maximum 2019
 
01:19
On 13 March 2019, Arctic sea ice appears to have reached its annual maximum extent. At 14.78 million square kilometers, it is the seventh lowest in the satellite record. The 2019 maximum extent is 860,000 square kilometers below the 1981 to 2010 average maximum of 15.64 million square kilometers and 370,000 square kilometers above the lowest maximum of 14.41 million square kilometers set on 7 March 2017.

Arctic Blue-Ocean-Event Consequences for Greenland: 1 of 2
 
15:01
Between 60,000 and 22,000 years ago there were numerous abrupt temperature fluctuations recorded by oxygen and nitrogen isotopes (paleo-thermometer proxies) in Greenland ice cores. Temperatures over parts of Greenland rose by up to 16.5 C within a decade or two, in the largest of these so-called Dansgaard-Oescher (D-O) Oscillations. I chat on the latest science, about how a lack of Arctic sea-ice was the primary factor. This is crucial info to help us figure out what will happen to Greenland when we have no surrounding sea ice left.

Disappearing Arctic sea ice
 
03:30
This visualization begins by showing the dynamic beauty of the Arctic sea ice as it responds to winds and ocean currents. Research into the behavior of the Arctic sea ice for the last 30 years has led to a deeper understanding of how this ice survives from year to year. In the animation that follows, age of the sea ice is visible, showing the younger ice in darker shades of blue and the oldest ice in brighter white. This visual representation of the ice age clearly shows how the quantity of older and thicker ice has changed between 1984 and 2016.

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.

Is a Year Round Ice Free Arctic Ocean in the cards?
 
14:59
Two videos ago I built the scientific case that Arctic sea ice would vanish in the first "blue-ocean" event by 2020. Last video I argued that it would be gone year round within a decade of that first disappearance. Will it vanish year round, or only for 6 months a year in summers? I examine some recent journal articles that touch on this question. We need the answer quickly, before it happens. Please support my videos at http://paulbeckwith.net

Arctic Sea Ice timelapse from 1978 to 2009
 
03:59
This movie is to show the complete 30 year history of the NSIDC satellite derived arctic sea ice extent in a single video. Brown is land, black is shoreline, blue is water except for the large blue dot in the center of the plot. The movie plays double speed at the beginning because the early satellite collected data every other day. Youll see the large blue circle change in size flashing back and forth between the older and newer sat data just as the video slows down. After staring at the graphs above you think you understand what is happening as ice gradually shrinks away. Well the high speed video shows a much more turbulent world with changing weather patterns in 2007 and 2008 summer blasting away at the south west corner of the ice. Ive watched it 20 times at least, noticing cloud patterns (causing lower ice levels), winds, water currents and all kinds of different things. Im not so sure anymore that were seeing a consistent decline to polar bear doom, with this kind of variance it might just be everyday noise. Note that despite some mainstream media reports, our Arctic Sea ice has not melted away, but comes back every year as it has done for millennia..This is the normal season cycle.

Arctic Sea Ice Loss : What's the latest?

NOAA released their 2018 Arctic Report Card back in December with some fairly stark warnings about the status of that region.

The First Arctic Blue Ocean Event.
 
08:01
The risk of the very first Arctic blue ocean event in human history occurring before 2020 is extremely high. This event involves the near complete annihilation of sea ice in the Arctic Ocean near the end of the summer. I discuss the Why, When, How and implications. Also, what we need to do to avoid it, and why this is vitally important for humanity.

Arctic Sea Ice Minimum Volumes 1979-2018
 
00:34
Latest visualization of the startling decline of Arctic Sea Ice up to 2018, showing the minimum volume reached every September since 1979, set on a map of New York with a 10km grid to give an idea of scale. It is clear that the trend of Arctic sea ice decline indicates that it'll soon be ice-free for an increasingly large part of the year, with consequences for the climate. The rate of ice loss in the Arctic is staggering. Since 1979, the volume of Summer Arctic sea ice has declined by more than 80% and accelerating faster than scientists believed it would, or even could melt. I also composed and played the piano music, "Ice Dreams". A longer version played live can be found here: https://youtu.be/_miBCygvO4Y About the data: Sea Ice Volume is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS, Zhang and Rothrock, 2003) developed at APL/PSC. Source data for this graph is available from http://psc.apl.washington.edu/wordpress/research/projects/arctic-sea-ice-volume-anomaly/ More information: The image first appeared in still form on Think Progress, and I decided to try to bring it to life over the following weeks: http://thinkprogress.org/climate/2013/02/14/1594211/death-spiral-bombshell-cryosat-2-confirms-arctic-sea-ice-volume-has-collapsed/ An earlier video also featured on BBC's Newsnight: http://www.bbc.co.uk/news/science-environment-19496674 I produced the animation using hand-written perl and php code to create povray scripts, and scheduling task distribution using MySQL between numerous disparate linux servers working in parallel to render 1000 frames at 1920 x 1080 resolution. This time the "farm" used a total of 62 processor cores over the space of 3 days. I even got a Raspberry Pi 3 B+ to help out, and contributed 11 frames taking about 3 hours each. Every little helped! On completion, ffmpeg combined the individual frames and music into a high quality mp4 video.

Arctic Sea Ice from January 1, 2013 to September 10, 2016
 
03:03
This visualization shows the daily Arctic sea ice and seasonal land cover change progress through time, from January 1, 2016, through September 10, 2016 when the sea ice reached its annual minimum extent for the year. The 2016 Arctic sea ice minimum is the second lowest minimum extent on the satellite record, 4.14 million square kilometers (1.60 million square miles). Here the sea ice changes from day to day showing a running 3-day minimum sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Satellite-based passive microwave images of the sea ice have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. The first six months of 2016 have been the warmest first half of any year in our recorded history of surface temperature (which go back to 1880). Data shows that the Arctic temperature increases are much bigger, relatively, than the rest of the globe. The Japan Aerospace Exploration Agency (JAXA) provides many water-related products derived from data acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument aboard the Global Change Observation Mission 1st-Water "SHIZUKU" (GCOM-W1) satellite. Two JAXA datasets used in this visualization are the 10-km daily sea ice concentration and the 10 km daily 89 GHz Brightness Temperature. Visualizers: Cindy Starr (lead), Trent L.

Arctic Blue Ocean Event Consequences: Air and Ocean Circulation Changes
 
15:01
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.

Weekly Arctic sea ice age between 1984 and 2016
 
01:28
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 4 meters thick. By contrast, first year ice that grows during a single winter is generally at most 2 meters thick. Below is an animation of the weekly sea ice age between 1984 and 2016. The animation shows the seasonal variability of the ice, growing in the Arctic winter and melting in the summer. In addition, this also shows the changes from year to year, depicting the age of the sea ice in different colors. Younger sea ice, or first-year ice, is shown in a dark shade of blue, while the ice that is at least four years old is shown as white. A color scale identifies the age of the intermediary years. A graph in the lower right corner 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 represents the current maximum value seen thus far in the animation 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 animation (January 1, 1984).

The Arctic Blue-Ocean-Event (BOE). When? Then What?
 
15:01
We are hurtling towards the Blue Ocean Event (BOE) in the Arctic. Nobody knows for sure when it will happen. From my analysis, which I discuss in this video, my best guess is that the BOE will happen in 2022. There will be essentially NO sea ice in the Arctic Ocean for a few weeks to a month in September, 2022. After this BOE happens, then what will follow in subsequent years? I think that by BOE+2 years the Arctic Ocean will be ice free for August, September, and October. By BOE+4 years it will be ice free for 5 months, and by BOE+10 years the Arctic Ocean will be free of sea ice year round. During this decade of gut-wrenching transition, our climate and weather patterns will be profoundly disrupted, chaotic, and unstable, for example presenting enormous risks to our global food supply. I am not paid by anybody for my work analyzing and producing these videos.

Persistent cyclones churning up Arctic sea-ice are bad news. Maximum Arctic sea-ice savagery occurred in 2012 from a massive long-lived August cyclone leading to the outstanding record September sea-ice minimum. We just had a big one in early June. There is almost no thicker multi-year ice left in the Arctic; what is left is thin, brittle, slushy, darker, and honeycombed with saline pockets like Swiss cheese.

Satellite records and declassified submarine sonar data show the Arctic sea ice thickness is in decline. 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.

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.

Now we have the technology to reach into the ocean depths, we accompanied scientist and deep-sea explorer Jon Copley and became the first to descend to 1000 meters underwater in Antarctica for Blue Planet II. The exotic creatures we found there will astonish you. This video is a part of Our Blue Planet, a joint venture between OceanX and BBC Earth to get people talking about the ocean.

Arctic Sea Ice Melt Patterns and Analysis
 
15:00
It appears that Arctic Sea-Ice will hang on for another year, as the melt season draws to a close for 2018. No blue-ocean event this year. However, the nature of the melt is definitely changing, and we can discern patterns in the melt from year to year. For example, at minimum-sea ice extent in Sept., 2014 there was still relatively thick ice (multi-year, and/or ridged ice) north of the Canadian Archipelago, but it pretty much vanished by the subsequent melt season. All that’s been left in September’s since then is ice less than a meter thick, apart from some 2 meter ice hanging on near the archipelago islands. What’s next? When? Why? Stay tuned for 3 more ice videos. Please support my video analysis with a donation at http://paulbeckwith.net

Fourth video of a series of four on the changing dynamics of Arctic Sea-Ice Loss (melt versus export) as we tease out clues as to when the first blue-ocean event will occur. Also, what will happen after the first blue-ocean event, both in the Arctic and elsewhere? How will things proceed in subsequent years, and what impacts will humanity have to face.

After First Arctic Blue-Ocean Event; then WHAT?
 
15:01
Let's say the Arctic Ocean Sea Ice completely vanishes by 2020 (or sooner) for the month of September. What happens afterwards to the ice. Does it vanish for longer and longer durations until it is gone year round? Do we reach a state with 6 months of ice in winter and open water all summer? Does something else happen?

Weekly Animation of Arctic Sea Ice Age with Two Graphs: 1984 - 2016
 
01:28
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.

Arctic's oldest ice each week since 1990
 
01:05
**Latest version available @https://www.youtube.com/watch?v=c6jX9URzZWg** (*Updated through 2015's summer minimum in September). Time lapse of the relative age of Arctic sea ice from week to week since 1990. The oldest ice (9 or more years old) is white. Seasonal ice is darkest blue. Old ice drifts out of the Arctic through the Fram Strait (east of Greenland), but in recent years, it has also been melting as it drifts into the southernmost waters of the Beaufort Sea (north of western Canada and Alaska). Video produced by the Climate.gov team, based on data provided by Mark Tschudi, University of Colorado-Boulder, with support from NASA.

Sorry Folks. Arctic Sea-Ice On Last Legs.
 
15:01
Arctic Sea Ice has been pulverized, hacked to pieces, smashed to smithereens; you can use whatever phrase you want. With a week or two left in the 2016 melt season, and another storm in the long range forecast, all bets are off. I discuss extent, area, thickness, volume, surrounding sea and air temperature, trends and what it means to us, lower-latitude mortals. Not a pretty picture; expand extreme weather events around the globe to notch up in frequency, severity and duration. I rely on you, my viewers to support my videos.

Arctic Sea Ice Timelapse (2005-2008) [1080p]
 
01:14
Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover. In this animation, the globe slowly rotates one full rotation while the Arctic sea ice and seasonal land cover change throughout the years. The animation begins on September 21, 2005 when sea ice in the Arctic was at its minimum extent, and continues through September 20, 2008. This time period repeats twice during the animation, playing at a rate of one frame per day. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Over the water, Arctic sea ice changes from day to day.

Last Gasp Arctic Sea Ice Death Rattle
 
15:01
Elaborating on my last video; I take a cold, hard look at the reality of vanishing Arctic sea-ice. All signs point to an Arctic in collapse. Cold air is flooding out of the Arctic, pushing the jet stream far south, putting North America in a highly variable deep freeze that will be seen in a few years as a “last gasp” Arctic “death rattle”. Unfortunately, our climate is highly nonlinear, and we have already crossed thresholds. The Arctic is the Achilles Heel or lynchpin of the entire system, and it is undergoing convulsions.

Demise of Arctic Sea-Ice: Part 1 of 2
 
15:00
There is very little Arctic sea-ice left this year. The trend is a rapid decline to essentially nothing (- 1 million square km); the "blue-ocean event" as I call it (should have trademarked this). If the ongoing massive cyclones continue to shred the ice over the next 4 or 5 weeks of this summers melt season than "nothing left" could be this year; otherwise before 2020 is an excellent wager. The devil is in the details; I teach you how to find the details (images) that you need to do your own assessment.
