A BOE would happen in the summer according to polar researchers and the ice could still refreeze in the winter. Currently we are seeing fast expansion, as over 2.5 million km² of fresh sea ice … A BOE would happen in the summer according to polar researchers and the ice could still refreeze in the winter. "The The energy needed to melt such a volume of ice is ~ 35 times the annual energy consumption of the U.S. Turn up the heat, and ice will melt. Newly discovered long-lived algae growing on the Arctic seafloor and forming tree-ring–like growth bands in a hard, calcified crust have recorded centuries of sea-ice history. Sometimes unbelievable that 90% of an iceberg is under water photo credit: Getty. Opinions expressed by Forbes Contributors are their own. The total amount of ice, which set a record low last year, grew in October at the fastest pace since record-keeping began in 1979. Dr. Patrick Michaels, Global air temperature records date back to the 1880s and can offer a stand-in (proxy) for Arctic sea ice conditions; but such temperature records were initially collected at just 11 locations. Arctic sea ice hit its winter maximum of 15.05m km2 – the 11th smallest on record – on 5 March. Around this time of year, Arctic sea ice stops melting and starts to increase again as northern hemisphere temperatures drop off. Arctic sea ice has melted to a level not recorded since satellite observations started in 1972 – and almost certainly not experienced for at least 8,000 years, say polar scientists. The Arctic sea ice and its related biota are unique, and the year-round persistence of the ice has allowed the development of ice endemic species, meaning species not found anywhere else.. The changes are associated with diminishing sea ice cover, according to a study published in the journal Biology Letters and led by the University of California, Davis. At the rate it's going, because of global cooling, it could soon be the greatest in at last 14 years. surface, and below the water surface. This day is an important day because the measurement taken will be used to analyze the state of the Arctic region and add to the growing body of knowledge of the fundamental changes that are taking place. Others aren't so sure. What Killed the Dinosaurs . The effect of climate change on the world’s ice is almost that simple. The image above shows the last 10 days adding sea ice at an average rate of 215k km2 per day. The image above shows the last 10 days adding sea ice at an average rate of 215k km2 per day.            papers announcing From there, on average 3.3 more feet of sea ice … Ice levels had been tracking lower throughout much of 2008, but rapidly recovered in the last quarter.… Thanks to a rapid rebound in recent months, global sea ice levels now equal those seen 29 years ago, when the year 1979 also drew to a close. Large areas of the Southern Pacific are showing cooling This day is an important day because the measurement taken will be used to analyze the state of the Arctic region and add to the growing body of knowledge of the fundamental changes that are taking place. The NASA research team found that in the 1980s, sea ice on average in the Arctic was 6.6 feet thick in October. On the CanAm side, Beaufort at the top left is iced over, Canadian Archipelago (center left) is frozen, and Baffin Bay is filling from the north down. Every summer, the Arctic ice cap melts to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. Credit: NSIDC Satellites provide a near-continuous record of Arctic sea ice cover, allowing scientists to monitor changes from one day to the next. The doubled rate of warming has led to increasingly smaller sea ice extents during Arctic summer months and an overall reduction in sea ice. Arctic sea ice has melted to a level not recorded since satellite observations started in 1972 – and almost certainly not experienced for at least 8,000 years, say polar scientists. nothing in the recent data to contradict predictions of global warming. In a December 2018 article, NASA claimed that Arctic sea ice had lost two-thirds of its thickness since 1958. Global Ice Center announced its review of Arctic Sea ice conditions during 2019.Sea ice is usually at its peak surface area in February or March of each year, and at its smallest in September. See Arctic Sea Ice Growing at Fastest Rate in Recorded History. The source of the data isn’t some hokey-pokey conspiracy site — it’s America’s NSIDC, who boast being backed-up by NASA–and they have … Also the ice volume. Sea ice coverage in the Arctic has shrunk at a much faster rate than it has expanded in the Southern Ocean. Thanks to a rapid rebound in recent months, global sea ice levels now equal those seen 29 years ago, when the year 1979 also drew to a close. At 5.10 million square kilometers or 1.97 million square miles, 2013 comes in 6th place for the smallest summer sea ice minimum extent in recorded history. While admitting that the Arctic has certainly been colder in This increased growth of sea ice has helped to slow down the overall reduction in Arctic sea ice and delayed an ice-free Arctic. As a quick overview, global ocean circulation is slowing down because overall Arctic ice levels are continuing to decline, causing a freshwater influx into the Northern Atlantic Ocean and a "cap" on the mechanism that drives global ocean circulation. sea level like the ice anchored on bedrock in Antarctica or Greenland. The energy needed to melt such a volume of ice is ~ 35 times the annual energy consumption of the U.S. Thanks to Kenneth Lund, Don et al, Brian Hicks for this link, Antarctic Ice This summer, the Arctic region saw record-breaking heat, and from the Laptev Sea to the Beaufort Sea, the sea ice area decreased at the fastest rate in the history of observation. "More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice—ice that was fully attached to the seafloor." After a record setting low in 2012, the 2013 summer sea ice extent rebounded – but only slightly. Professor of Environmental Science at the University of Virginia, says in Recorded History Arctic Icebergs Greenland in the arctic sea. Norway's ice service said Svalbard's sea ice area for 21 August was 111,968 sq km, adding "this is 115,969 sq km below the 1981-2010 average". on a A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year. bringing ice back to levels from the 1980s. The graph above by NASA shows an average 12.8 percent decline in average September sea ice extent, with the rate of decline increasing since the 1990s. Another positive factor of the increased growth in wintertime Arctic sea ice is the impact it has on global circulation. Arctic sea ice reached its smallest extent for the year on September 10, tying for the second-smallest minimum size on record. On average, ice covers roughly 7% of the ocean In reality the Arctic sea-ice volume is the greatest it has been in 4 years. I am, I am a geologist passionate about sharing Earth's intricacies with you. The Southern On September 16, 2012, Arctic sea ice spread across just 3.41 million square kilometers (1.32 million square miles)—the smallest extent ever recorded by satellites and about half the average minimum from 1981 to 2010. Global Ice Center announced its review of Arctic Sea ice conditions during 2019.Sea ice is usually at its peak surface area in February or March of each year, and at its smallest in September. By increasing the rate at which wintertime sea ice forms, the freshwater cap could be limited for a time. Average monthly Arctic sea ice extent in September between 1979 and 2015 (at a rate of 13.4% per decade). "Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new NASA study finds. Arctic Sea Ice Growing at Fastest Rate in Recorded History _____  7 Nov 08 - An abnormally cool Arctic is seeing dramatic changes to ice levels. (2010) looked at Arctic sea ice changes throughout geologic history and noted that the current rate of loss appears to be more rapid than natural variability can account for in the historical record. Unlike the Arctic, where sea ice extent is declining in all areas in all seasons, Antarctic trends are less apparent. October 2019 was quite a wild ride as far as Arctic sea-ice goes. The widely publicized sea ice decreases in the Arctic, even with their worrisome acceleration in the early 21st century, have never experienced (in the 40-y 1979–2018 record) a 4-y period with a rate of decrease in yearly average ice extents exceeding in magnitude a value of −240,000 km 2 ⋅y −1 (Fig. Polyak et al. Winter... [+] landscape with snow-covered rocks and seacoast and sunset sky. The seasonal low point in Arctic sea ice extent in September is also declining at a rate of 13.4 percent per decade. Arctic sea ice hit its winter maximum of 15.05m km2 – the 11th smallest on record – on 5 March.            years.” Where are Arctic sea ice is melting at its fastest rate in 1,500 years and the warmer winters are suggesting disastrous changes to come. The Russian shelf seas on the right have filled with ice in this period. Sea ice is floating and therefore doesn't affect However, a BOE is not considered a complete meltdown, just an indication of an impending one. The total amount of ice, which set a record low last year, grew in October at the fastest pace since record-keeping began in 1979. Some researchers, not surprisingly, say the rapid increase is "no big Arctic Sea Ice Extent “Extensive Modern Sea Ice Conditions” during spring (80% concentrations), but “Consistently Low” and “Marginal” (<10%) Sea Ice conditions from 10,500 To 1,500 years before present. The sea ice satellite record dates back to October 25, 1978. On the CanAm side, Beaufort at the top left is iced over, Canadian Archipelago (center left) is frozen, and Baffin Bay is … The Russian shelf seas on the right have filled with ice in this period. All Rights Reserved, This is a BETA experience. This is another example of how Earth's systems work to counterbalance and mitigate changes in some systems, much like the three branches of the US government. In contrast, in the Antarctic the sea ice coverage has been increasing although at a lesser rate than the decreases in the Arctic. Wintertime Arctic sea ice growth slows long-term decline: NASA – Climate Change: Vital Signs of the Planet. Contrary to claims that modern day sea ice changes are “unprecedented”, alarming, and well outside the range of natural variability, biomarker proxies used to reconstruct both Arctic and Antarctic sea ice conditions since the Early Holocene increasingly reveal that there is more extensive Arctic and Antarctic sea ice during recent decades than for nearly all of the last … The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. The arctic sea ice anomaly at that point was -1.425 million sq kms. I received my PhD from Duke University where I studied the geology and climate of the Amazon. Around this time of year, Arctic sea ice stops melting and starts to increase again as northern hemisphere temperatures drop off. They said the current area was the lowest on record. The multi-year (i.e. Based on the Kinnard results, Arctic sea ice extent is currently lower than at any time in the past 1,450 years. So much for the supposed “death spiral” , positive feedbacks and “tipping points” all driven by wicked CO2 . Arctic Sea Ice Growing at Fastest more sea ice?" Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. Arctic sea ice extent in January 2020 is sitting ABOVE levels observed in the years 2019, 2018, 2017, 2016, 2015, 2012 (record low extent), 2011, AND 2010.. Can you imagine the likes of The Guardian, for example, ever running with this? Sometimes unbelievable that 90% of an iceberg is under water photo credit: Getty, landscape with snow-covered rocks and seacoast and sunset sky. Rate deal". This summer, the Arctic region saw record-breaking heat, and from the Laptev Sea to the Beaufort Sea, the sea ice area decreased at the fastest rate in the history of … Now that the Arctic melt season has started in earnest, we find a surprising trend. If the land ice is melting but the sea ice is increasing" In reality, Arctic sea ice is at a record low and global sea ice is diminishing. So while there's still lots of snow and ice in the polar regions, there’s much less of it than there used to be. Arctic Sea Ice. Over the past few decades, sea ice across the Arctic Ocean has gotten smaller and thinner. Arctic Sea Ice Growing at From August 1 to August 31, NASA data show that arctic sea ice extent declined at a rate of 32,700 square miles per day, compared to a rate of about 24,400 square miles per day in August 2007. trend – has also been gaining ice in recent However, a BOE is not considered a complete meltdown, just an indication of an impending one. During August, the Arctic lost an average of 35,400 square miles of ice per day, which was the fastest rate ever observed for the month. Temperatures in the Arctic have warmed much faster than temperatures in tropical locations. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2020, with a graph overlay. Arctic sea-ice volume was higher on June 1st than on the same date in 2011 and far, far higher than on the same date in 2012, 2016 and 2017. However, research has indicated that the Antarctic continent -- which is As a result, ice sheets and glaciers melt and shrink. Compared to the 1980s, today's end-of-summer Arctic sea ice extent is about half. The March 2020 Arctic sea ice extent was 14.78 million square kilometers (5.71 million square miles). The seasonal low point in Arctic sea ice extent in September is also declining at a rate of 13.4 percent per decade. The total amount of ice, which set a record low last year, grew in October at the fastest pace since record-keeping began in 1979, bringing ice back to levels from the 1980s. Weathernews Inc. The winter ice around the southern continent has been growing relatively constantly since records began in 1979. Natural News cites a climate change denial blog called ClimateDepot.com as evidence of the claim that sea ice has grown 40 percent since 2012. It started as the 3rd lowest on record, and it finished in monthly average as record lowest October on record! This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2020, with a graph overlay. Global temperatures are warming, and that warming is fastest at the poles. See Arctic Sea Ice Growing at Fastest Rate in Recorded History. The story lies in the magnitudes of both changes. Sheet growing enough to lower sea levels, http://www.dailytech.com/Sea+Ice+Growing+at+Fastest+Pace+on+Record/article13385.htm. This was the eleventh lowest in the satellite record, 650,000 square kilometers (251,000 square miles) below the 1981 to 2020 March average and 490,000 square kilometers (189,000 square miles) above the record low March extent in 2017. In contrast, in the Antarctic the sea ice coverage has been increasing although at a lesser rate than the decreases in the Arctic. At 4.41 million square kilometers or 1.79 million square miles, 2015 was the fourth-smallest summer sea ice minimum extent in recorded history. The algae show that, while fast short-term changes have occurred in the past, the 20th century exhibited the lowest sea-ice cover in the past 646 years. The Arctic sea ice covers less area in the summer than in the winter. trends, an occurrence not anticipated by any current climate model, H owever, far from record lows, this year the Arctic has seen the quickest refreeze ever recorded with the extent of sea ice growing 405,000 square miles (1.05 … However, ultimately the warming summer temperatures continue to overall reduce the extent of sea ice. Hyderabad: A recent study by the National Centre for Polar and Ocean Research (NCPOR), Goa, India, has pointed out that the Arctic sea ice is melting at an alarming rate especially during boreal or northern hemisphere summer.The study published in the journal Heliyon, highlights the increasing decline of the Arctic sea ice due to climate change. This chart … Credit: NSIDC Satellites provide a near-continuous record of Arctic sea ice cover, allowing scientists to monitor changes from one day to the next. Rapid growth spurt leaves amount of ice at levels seen 29 years ago. While the Arctic sea ice is growing faster and higher during the winter months, it is more than offset by the melting in the summer months. The black line on the chart below shows current Arctic sea-ice volume. years. The 2007 melt season let to a minimum 39% below the 1979–2000 average, and for the first time in human memory, the … in October at the fastest pace since record-keeping began in 1979, recent months, they say the long-term decrease is still ongoing and see The Arctic sea ice September minimum extent (i.e., area with at least 15% sea ice coverage) reached new record lows in 2002, 2005, 2007, and 2012. ______________________________. Arctic Sea Ice. The winter ice around the southern continent has been growing relatively constantly since records began in 1979. At 4.41 million square kilometers or 1.79 million square miles, 2015 was the fourth-smallest summer sea ice minimum extent in recorded history. Arctic Sea Ice Growing at Fastest Rate in Recorded History 7 Nov 08 - An abnormally cool Arctic is seeing dramatic changes to ice levels. NASA makes sure to clearly note that this doesn't mean climate change isn't taking place, that our planet is not warming and that the overall amount of sea ice isn't declining in the Arctic. Natural News cites a climate change denial blog called ClimateDepot.com as evidence of the claim that sea ice has grown 40 percent since 2012. — Köseoğlu Et Al., 2018 “Lower Than Modern” Sea Ice Conditions between 2,200 and 1,200 years before present. Every summer, the Arctic ice cap melts to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. At 5.10 million square kilometers or 1.97 million square miles, 2013 comes in 6th place for the smallest summer sea ice minimum extent in recorded history. At the rate it's going, because of global cooling, it could soon be the greatest in at last 14 years. Top view of Norwegian Fjords at dusk photo credit: Getty, EY & Citi On The Importance Of Resilience And Innovation, Impact 50: Investors Seeking Profit — And Pushing For Change, Michigan Economic Development Corporation BrandVoice, While global ocean circulation continues to slow down. From August 1 to August 31, NASA data show that arctic sea ice extent declined at a rate of 32,700 square miles per day, compared to a rate of … The black line on the chart below shows current Arctic sea-ice volume. the breathless headlines in the world's news- It has since been on its annual decline through the melt season of spring and summer. Other, scattered records of Arctic sea ice date back to the mid-1700s, when sailors kept notes on Northern Hemisphere shipping lanes. Shown below are up-to-date satellite observations of the sea ice covers of both the Arctic and the Antarctic, along with comparisons with the historical satellite record of more than 37 years. perennial) sea ice covers nearly all of the central deep basins. Hemisphere can't be explained by current theory, says Michaels. I am a geologist passionate about sharing Earth's intricacies with you. But this New York Times article from 1958 shows that sea ice thickness in 1958 was two meters, same as December, 2018. Michaels adds. This Arctic sea ice loss occurred with the solar TSI languid for many decades & low for 10+ years (including a 3+ year period in which TSI set a 100 year record low). . Fastest Rate in Recorded History, Discover However, the seemingly inevitable ice-free Arctic will win out in the end, adds NASA. Though less Arctic sea ice melted in 2013 compared to 2012, this year’s total is the sixth lowest in the satellite record. This chart shows the disturbing trend over the last thirty years.            Did you catch that? See entire article: surface of the planet. The latest edition of the NSIDC’s “Arctic Sea Ice News” has been published. At the end of the month, extent was particularly low in the Bering Sea after a rapid retreat during the second half of the month. (Phys.Org) It is a interesting after the warmest decade “in recorded history” that minimum Arctic sea ice area/extent has been increasing for the last 6 years. models predict a warming ocean around Antarctica, so why would we see From there, on average 3.3 more feet of sea ice would form through the winter. Top view of Norwegian Fjords at dusk photo credit: Getty. A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year. Arctic sea ice VOLUME loss was ~10200 cubic kilometers. So what we've seen is that the increased rate of sea ice growth in the winter helps to mitigate the melting during the summer. on a long-term cooling trend -- has also been gaining ice in recent levels. While global ocean circulation continues to slow down, increased Arctic sea ice growth could help to mitigate the slowing. A recent study by NASA found that sea ice is growing faster during the winter months today than it did decades ago. Ice levels had been tracking lower throughout much of 2008, but rapidly recovered in the last quarter.… Amongst other interesting information it reveals that: Sea ice extent for October 2020 was 5.28 million square kilometers (2.04 million square miles), placing it lowest in the satellite record for the month. Average monthly Arctic sea ice extent in September between 1979 and 2015 (at a rate of 13.4% per decade). Shown below are up-to-date satellite observations of the sea ice covers of both the Arctic and the Antarctic, along with comparisons with the historical satellite record of more than 37 years. Contrary to claims that modern day sea ice changes are “unprecedented”, alarming, and well outside the range of natural variability, biomarker proxies used to reconstruct both Arctic and Antarctic sea ice conditions since the Early Holocene increasingly reveal that there is more extensive Arctic and Antarctic sea ice during recent decades than for nearly all of the last 10,000 years. In reality the Arctic sea-ice volume is the greatest it has been in 4 years.            long-term cooling I am the founder of Science Trends, a leading source of science news and analysis on everything from climate change to cancer research. There are differing scientific opinions about … The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. and Why it Could Soon Kill Us, . This Arctic sea ice loss occurred with the solar TSI languid for many decades & low for 10+ years (including a 3+ year period in which TSI set a 100 year record low). I predicted that the arctic sea ice anomaly would actually grow in the next several weeks. So how can it be that sea ice is declining in the Arctic but wintertime growth is increasing? 7 Nov 08 - An abnormally cool Arctic is seeing dramatic changes to ice he sees some "very odd" things occurring in recent years. H owever, far from record lows, this year the Arctic has seen the quickest refreeze ever recorded with the extent of sea ice growing 405,000 square miles (1.05 million square kilometres) in … Weathernews Inc. It reports that, September sea ice … this fact? (See Antarctic Ice “The Antarctic continent -- which  is Comparing that to today, where average sea ice in the Arctic is 3.3 feet thick in October but will grow on average 5 feet more of sea ice through the winter. The (then-record) 2012 Antarctic sea ice extent; compare with the yellow outline, which shows the median sea ice extent in September from 1979 to 2000. Hyderabad: A recent study by the National Centre for Polar and Ocean Research (NCPOR), Goa, India, has pointed out that the Arctic sea ice is melting at an alarming rate especially during boreal or northern hemisphere summer.The study published in the journal Heliyon, highlights the increasing decline of the Arctic sea ice due to climate change. http://www.dailytech.com/Sea+Ice+Growing+at+Fastest+Pace+on+Record/article13385.htm From 1979–2017, Antarctic-wide sea ice extent showed a slightly positive trend … Hence, the combined sea ice thickness in the 1980s was 9.9 feet thick, compared to 8.3 feet thick today. Since 1958, Arctic sea ice lost about two-thirds of its thickness, with nearly three-quarters of Arctic sea ice forming and melting each year. Ice los… . The NASA research team found that in the 1980s, sea ice on average in the Arctic was 6.6 feet thick in October. It has since been on its annual decline through the melt season of spring and summer. Arctic Sea Ice Growing at Fastest Rate in Recorded History 7 Nov 08 - An abnormally cool Arctic is seeing dramatic changes to ice levels. Arctic sea ice VOLUME loss was ~10200 cubic kilometers. You may opt-out by. The negative feedback of increasing rate of wintertime sea ice growth will help slow down the overall decline in Arctic sea ice. The total amount of ice, which set a record low last year, grew Let's connect @trevornace, © 2020 Forbes Media LLC. In mid-September he wrote that arctic sea ice was growing the fastest in history for September. Rapid growth spurt leaves amount of ice at levels seen 29 years ago. You can easily see that iceberg is over the water... [+] surface, and below the water surface. After a record setting low in 2012, the 2013 summer sea ice extent rebounded – but only slightly. As Arctic sea ice continues to melt—exposing more of the ocean’s surface to the atmosphere—some scientists believe there’s a chance more of … ... said the rising temperatures pose growing … The widely publicized sea ice decreases in the Arctic, even with their worrisome acceleration in the early 21st century, have never experienced (in the 40-y 1979–2018 record) a 4-y period with a rate of decrease in yearly average ice extents exceeding in magnitude a value of −240,000 km 2 ⋅y −1 (Fig. Arctic sea ice is melting at its fastest rate in 1,500 years and the warmer winters are suggesting disastrous changes to come.
