For more information, visit http://www.nasa.gov/content/goddard/antarctic-sea-ice-reaches-new-record-maximum http://www.nasa.gov/content/goddard/qa-what-is-happening-with-antarctic-sea-ice The Arctic and the Antarctic are regions that have a lot of ice and acts as air conditioners for the Earth system. This year, Antarctic sea ice reached a record maximum extent while the Arctic reached a minimum extent in the top ten lowest since satellite records began. One reason we are seeing differences between the Arctic and the Antarctic is due to their different geographies. As for what's causing the sea increase in the Antarctic, scientists are also studying ocean temperatures, possible changes in wind direction and, overall, how the region is responding to changes in the climate.

Sub for more: http://nnn.is/the_new_media | Like the nag of a dripping faucet, the liberal news media spent years warning about melting glaciers and ice caps because of global warming. Media outlets predicted an “ice-free” Arctic time and again, and so far have been wrong. But with all the panic about melting glaciers, or sea ice, or ice at the poles the media have reported, one would imagine good news about increasing ice would at least get some attention. Not from the broadcast networks anyway. In the past year, they’ve ignored data showing increasing ice in Antarctica, presumably because it did not fit perfectly with their climate agenda, instead choosing to hype melting Arctic ice repeatedly.

We learned last year that many of the effects of climate change are irreversible. Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century. As National Geographic showed us in 2013, sea levels would rise by 216 feet if all the land ice on the planet were to melt. This would dramatically reshape the continents and drown many of the world's major cities.

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

But rather than sit by and watch as the sea ice disappears from the region at an unprecedented rate, scientists have hatched a crazy plan to 'refreeze' the Arctic, by installing some 10 million wind-powered pumps over the ice cap to spray sea water over the surface and replenish the sea ice." Arctic ice management http://onlinelibrary.wiley.com/doi/10.1002/2016EF000410/full "As the Earth's climate has changed, Arctic sea ice extent has decreased drastically. It is likely that the late-summer Arctic will be ice-free as soon as the 2030s. This loss of sea ice represents one of the most severe positive feedbacks in the climate system, as sunlight that would otherwise be reflected by sea ice is absorbed by open ocean. It is unlikely that CO2 levels and mean temperatures can be decreased in time to prevent this loss, so restoring sea ice artificially is an imperative." How a giant space umbrella could stop global warming http://www.bbc.com/future/story/20160425-how-a-giant-space-umbrella-could-stop-global-warming "The race to find a solution to a rapidly warming world is one of the most pressing challenges facing our planet. One proposal to try to halt this warming is literally out-of-this-world: a giant, space-based sunshade. We're already modifying our climate by accident, so why not do it by deliberate geoengineering? It's a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

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 ice parameters derived from satellite ice concentration data that are most relevant to climate change studies are sea ice extent and sea ice area. This graph displays the area of the minimum sea ice coverage each year from 1979 through 2013. In 2013, the Arctic minimum sea ice covered an area of 4.704 million square kilometers. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 to 2013 as derived from SSMI data. A semi-transparent graph overlay shows the area in million square kilometers for each year's minimum day. The date shown in the upper right corner indicates the current year being displayed.

Alarmism is not new. The fear mantra in mass media is a staple in a world dominated by oligarchic control. The ruse is deep and perpetrated at the highest levels to obfuscate the truth and control the narrative. In this video we show how alarm-ism historically is simply nonsense fairy-tales perpetrated by the media and supported by government agencies. Learn how to see through the mist as we uncover the truth about climate and the future of our planet. Using actual data sets uncomprimised by the global warming ruse. Historical data is also important to peruse as well, in order to reveal the clues of the past which will secure our future. http://www.snopes.com/politics/graphics/globalwarming.jpg https://ronmamita.files.wordpress.com/2015/10/global-warming-scam.jpg https://realclimatescience.com/wp-content/uploads/2017/03/Screen-Shot-2017-03-19-at-7.30.14-AM.gif https://climatedenierdotme.files.wordpress.com/2014/11/screenhunter_4674-nov-16-18-59.gif?w=566&h=234 https://i1.wp.com/realclimatescience.com/wp-content/uploads/2015/10/Image-431.png https://climatedenierdotme.files.wordpress.com/2014/11/screenhunter_4681-nov-16-22-25.gif https://climatism.files.wordpress.com/2017/07/gore-ice-free-2014.png?w=590 https://realclimatescience.com/wp-content/uploads/2016/07/2016-07-20045516.png https://thepolarhub.org/sites/default/files/ArcticSeaIce_2050ProjectedMinimum_Overlay.png https://realclimatescience.com/wp-content/uploads/2017/08/Image222_shadow.png http://notrickszone.com/wp-content/uploads/2017/03/Arctic-Sea-Ice-Iceland-Koch-Since-1200.jpg https://tallbloke.wordpress.com/2013/07/18/lassen-and-thejll-close-correlation-found-between-solar-activity-and-arctic-ocean-climate/ https://wattsupwiththat.com/reference-pages/sea-ice-page/ http://nsidc.org/arcticseaicenews/ https://neptune.gsfc.nasa.gov/csb/index.php?section=234 https://polarbearscience.files.wordpress.com/2015/05/crockford-unofficial-polar-bear-numbers-to-2015-sept-1-final1.jpg https://upload.wikimedia.org/wikipedia/commons/thumb/b/b4/Atlantic_Multidecadal_Oscillation.svg/800px-Atlantic_Multidecadal_Oscillation.svg.png https://www.ncdc.noaa.gov/sotc/service/global/nh-seaice/201509.gif http://nsidc.org/arcticseaicenews/files/2013/10/Figure3_Sept2013_trend.png https://realclimatescience.com/wp-content/uploads/2017/02/Screen2-Shot-2017-02-14-at-6.17.49-AM.gif http://2.bp.blogspot.com/-Z2zRUrq4Nrc/UXy4WG0IalI/AAAAAAAAASw/2wiwxnuV96Q/s640/arctic_mean_anomaly_1953-2011.png https://realclimatescience.com/ http://i1.wp.com/www.powerlineblog.com/ed-assets/2016/06/climate-civilization-gisp-chart.png https://realclimatescience.com/wp-content/uploads/2017/01/Screen-Shot-2017-01-05-at-8.03.14-AM-1024x539.gif http://www.drroyspencer.com/wp-content/uploads/UAH_LT_1979_thru_August_2017_v6.jpg NOAA : Hiding Critical Arctic Sea Ice Data: https://youtu.be/nIEGo8E9s_8 If you liked what you saw pleas SUBSCRIBE to our channel.

Such shelves are important because they hold back a vast amount of ice. If all such West Antarctic shelves were to collapse and spill the ice into the ocean then global sea level would rise by 10 feet. Beneath the Ross Ice Shelf is one of the least explored bits of ocean on Earth. New Zealand scientists used a hot-water drill hose to create a hole through the thick ice until they reached the perpetually dark water. They hoped to study the health and history of the shelf. Their findings surprised them. They found that the ice in the hole itself and along the base of the shelf was crystalizing and freezing rather than melting. Measurements will be taken for the next few years, to see how the Ross Ice Shelf is changing over time.

Our CEO and chief scientist Ben Strauss went on air with Hari Sreenivasen of PBS NewsHour to talk through a new study on Antarctic ice melt and what that may mean for coastal cities in the U.S. — particularily on the East Coast. "South Florida is severely at risk particularly because their bedrock is porous. So even if you built levees or protected walls, water would push underneath them come up through the ground. So there are really high stakes here." Antarctica, a continent of snow and ice, is now losing ice three times faster than it was in 2007. In a new study published last week in the journal Nature, more than 80 scientists from multiple countries use satellite data to examine the Antarctic’s vast ice sheets, and their prediction is that if the current rate of ice melt continues, sea levels could rise six inches by the year 2100.

In the near future, the North Pole could truly be relegated to the realm of history. In fact, since scientists started measuring winter sea ice, we’ve lost half a million square miles of it—and for every additional ton of carbon dioxide in the air, about 32 square feet of summer sea ice disappears. In this episode of You Are Here, The Atlantic writer Robinson Meyer details the history of the mythical North Pole and its uncertain future.

Under the Antarctica - Full Documentary HD The Antarctic ice sheet is one of the two polar ice caps of the Earth. 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 and contains 26.5 million cubic km of ice. That is, approximately 61 percent of all fresh water on the Earth is held in the Antarctic ice sheet, an amount equivalent to 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. The land in this area would be seabed if the ice sheet were not there. The icing of Antarctica began with ice-rafting from middle Eocene times about 45.5 million years ago and escalated inland widely during the Eocene - Oligocene extinction event about 34 million years ago. CO2 levels were then about 760 ppm and had been decreasing from earlier levels in the thousands of ppm. Carbon dioxide decrease, with a tipping point of 600 ppm, was the primary agent forcing Antarctic glaciation. The glaciation was favored by an interval when the Earth's orbit favored cool summers but Oxygen isotope ratio cycle marker changes were too large to be explained by Antarctic ice-sheet growth alone indicating an ice age of some size. The opening of the Drake Passage may have played a role as well though models of the changes suggest declining CO2 levels to have been more important. Ice enters the sheet through precipitation as snow. This snow is then compacted to form glacier ice which moves under gravity towards the coast. Most of it is carried to the coast by fast moving ice streams. The ice then passes into the ocean, often forming vast floating ice shelves. These shelves then melt or calve off to give icebergs that eventually melt. If the transfer of the ice from the land to the sea is balanced by snow falling back on the land then there will be no net contribution to global sea levels. A 2002 analysis of NASA satellite data from 1979 - 1999 showed that while overall the land ice is decreasing, areas of Antarctica where sea ice was increasing outnumbered areas of decreasing sea ice roughly 2:1. The general trend shows that a warming climate in the southern hemisphere would transport more moisture to Antarctica, causing the interior ice sheets to grow, while calving events along the coast will increase, causing these areas to shrink. A 2006 paper derived from satellite data, measures changes in the gravity of the ice mass, suggests that the total amount of ice in Antarctica has begun decreasing in the past few years. Another recent study compared the ice leaving the ice sheet, by measuring the ice velocity and thickness along the coast, to the amount of snow accumulation over the continent. This found that the East Antarctic Ice Sheet was in balance but the West Antarctic Ice Sheet was losing mass. This was largely due to acceleration of ice streams such as Pine Island Glacier. These results agree closely with the gravity changes. The estimate published in November 2012 and based on the GRACE data as well as on an improved glacial isostatic adjustment model indicates that an average yearly mass loss was 69 ± 18 Gt/y from 2002 to 2010. The West Antarctic Ice Sheet was approximately in balance while the East Antarctic Ice Sheet gained mass. The mass loss was mainly concentrated along the Amundsen Sea coast.
