Antarctic ice melt: What’s the difference?


You’ve heard that Arctic sea ice is melting You know that’s a big deal for climate change But what have you heard about the Antarctic? Most of us probably think that the Arctic and the Antarctic are pretty similar One’s at the top with polar bears, one’s at the bottom with penguins They’re both cold But while the Arctic is an ocean surrounded by land, the Antarctic is a land mass surrounded by ocean And that matters for climate change because sea ice and land ice are not the same thing We know the Arctic has been melting for the last thirty years But the reason you’ve heard less about the Antarctic is that much of it remains a mystery Antarctica is massive and inhospitable which makes it difficult and expensive to get to so it’s very hard to monitor and establish clear trends And what we do know is kind of confusing Last year, just as the Arctic sea ice dropped to a record low so too did the sea ice surrounding the Antarctic But three years before that, it hit a record high Scientists aren’t sure why it’s varied so much recently Now most of the sea ice that forms around the Antarctic isn’t permanent It disappears every summer But the ice in the Arctic remains year round meaning it can reflect more of the sun’s rays a process that’s important for cooling the planet But when it comes to sea level rise, the melting of sea ice does not in itself contribute It’s like an ice cube in a glass of water The water has already been displaced, so when the ice melts the water doesn’t rise any further But the warming Arctic means that the Greenland ice sheet is now starting to melt and that does mean that sea levels rise because Greenland is land ice And of course, so too is the Antarctic continent and there’s an awful lot of it In fact, Antarctica holds 90% of the world’s ice If it melted, the oceans would rise by 60 metres Now don’t panic, nobody is saying that the whole of Antarctica is going to melt But in general, scientists think that it’s losing more ice than it’s gaining This is not only bad news for the climate It’s also bad news for the animals that depend on the ice It can’t all be blamed on warming temperatures but in some parts of Antarctica, penguin populations are already in decline and scientists think it could get a lot worse if carbon emissions don’t drop Some seal and whale species could also be at risk And perhaps the greatest cause for concern is around one of the smallest creatures on the planet: krill They’re the basis of most of the Antarctic food web so if their numbers decline significantly it could trigger changes across the marine ecosystem Because the Antarctic is so big the warming and ice loss varies a lot from place to place At the moment, scientists are keeping their eye on a number of important big glaciers in the west Take Thwaites glacier for example, one of the biggest in the world This glacier is already thought to be contributing around 4% of global sea level rise Scientists aren’t just worried about a slow melt of the glacier itself They think it’s acting as a plug so that if it collapsed, it could trigger a domino effect that could release enough ice to increase sea levels by 60cm To put that in context since 1900, sea levels have risen by about 20cm Scientists disagree about when this could happen It could be centuries or even millennia away But it poses a serious risk to low-lying cities around the world and because of changes to Earth’s gravitational pull it would actually affect the Northern Hemisphere the most (Don’t ask me to explain how that works) So even though the Antarctic might seem very far away what happens there affects us all

  1. This was really neat and easy to understand. I loved all the animals. It'd be interesting to see something that looks like this with how pipelines and fracking effect the local animals and wildlife. And us obviously. So many being proposed on the East coast. Either that or something on the proposed seismic blasting ships coming for the Atlantic. Hopefully MA and other eastern states keep them from happening. Thanks for all you do. I can't so much but I donate $27 to Greenpeace each month. Thank you for fighting and informing 🙂

  2. "Other parts of the polar region off the northern coast of Greenland have seen temperatures 30C higher than normal for February".

    Just digest that number for a minute.

    What would you do if you woke up tomorrow and the temperature was 30C higher than normal ?

    I'll quote "President Niinistö in North Russia: ‘If We Lose the Arctic, We Lose the World’.

    what it's worth I'll continue to chronicle the unraveling of the biosphere but I don't expect it to hold together much longer.

    The sea ice in the Arctic is retreating from the melting temperatures from both the ocean and atmospheric anomalies.

    Soon the sun will rise in the Arctic and put the retreat on steroids and we are still 7 months away from the traditional low period.

    Will we see the 50 gigatonne methane release that has been predicted by Dr's Shakova and Smiletov from the University of Fairnbanks in Alaska. Only time will tell and time has run out." Kevin Hester

    "Human-Caused Climate Change is Causing the Most Powerful Hurricanes to Grow Stronger.

    That's why scientists are now mulling over adding a new category to define the world's most destructive storms: Category 6.

    Advanced by scientists meeting with Dr. Michael Mann in New Zealand and alluded to for the past few years in cutting edge blogs like Weather Underground,

    A 6th Category would be used to define storms with top sustained wind speeds that exceed 200 mph. Robert Scribbler

    A large area around the North Pole is forecast be up to 30°C or 54°F warmer than 1979-2000 on February 5, 2018." Sam Carana

    But it has been enhanced by more than a century of people externalizing the environmental costs of stupendous economic growth, loading the atmosphere now with
    42 percent more carbon dioxide,
    240 percent more methane,
    20 percent more nitrous oxide,
    42 percent more tropospheric ozone, etc.
    We have far too much gaseous carbon compounds now in our atmosphere, people.
    The carbon pollution is, by the way, making our oceans too acidic, an 3x more Mercury, threatening the base of the marine food chain. ” Jason E. Box

    "Billion-Dollar Weather and Climate Disasters:
    In 2017, there were 16 weather and climate disaster events with losses exceeding $1 billion each across the United States.
    These events included
    1 drought event,
    2 flooding events,
    1 freeze event,
    8 severe storm events,
    3 tropical cyclone events, and

    Christopher C. Burt, " the highest reliably recorded temperature on Earth is still at Death Valley, it is 54.0 °C (129.2 °F) recorded on 30 June 2013.

    53.9 °C (129.0 °F) was recorded another four times: 20 July 1960, 18 July 1998, 20 July 2005, and 7 July 2007.

    Aug 15, 2012 – "According to Weather Underground, the city of Needles, California, recently experienced what is believed to be the hottest rainfall on record 115°F."

    A 2015 heat wave that killed at least 3,500 in India and Pakistan saw wet-bulb temperatures around 122 degrees Fahrenheit (50 degrees Celsius).

    A similar wet-bulb temperature was reached during the 1995 Chicago heat wave." Steven Leahy

    A temperature of 94 degrees Fahrenheit (34.4 degrees Celsius) and 80% humidity produces a wet-bulb or “feels like” temperature of 129 degrees Fahrenheit (53.9 degrees Celsius) on the NOAA National Weather Service Heat Index.

    Methane which is Natural Gas + Carbon + Water Vapor = Global Warming

    Methane which is Natural Gas + Carbon + Water Vapor = Global Warming

    Methane holds 4 Times More Water Vapor than Carbon

    "The 20 year global warming potential of methane is 86. That is, over a 20 year period, it traps 86 times more heat per mass unit than carbon dioxide" IPPC

    "This means that injecting 1 kg of CH4 into the atmosphere today would have 86 times more atmospheric warming effect over the next 20 years than injecting 1 kg of CO2." ACS Chemistry for life.

    Then after 20 years it goes down to Methane GWP 34 for the next 100 years

    These figures are conservative

    Sam Carana "the 10 year holding more heat trapping mass and holding four times more water vapor than Carbon,

    Methane GWP 130 at 10 years,"

    This is why it is so hot in the Arctic 30C. – 40C. above Normal are Jet Stream is Lobed and it is melting in the Arctic NOW

    Astoundingly Truthful.

    That means 130 times more heat trapping mass and 4 times more water vapor than Carbon, is the Main Driver of Global Warming, Abrupt climate Change, Sea Level Rising over 220 feet, Faster Than They Say, Faster Than you think !

    Isostatic Rebounding of Greenlands Tectonic Plate, affecting (Gakkels Rift), causing Earthquakes in the Arctic, as well as Venting Mantle Methane

    Arctic News Sept. 15 2013
    “ As more ice melts away on Greenland and more water runs off in the Ocean and Sea, There is less weight on Greenlands Crust, the Crust Bouncing back from the lighter weight.

    The Crust bouncing back during Large Melts an effect called Isostatic Rebounding.

    This Rebounding can not Only Trigger Earthquakes and Landslides, it can also Suck Up the Magma from the Mantle.

    It Also Sucks Up Magma From The Mantle.

    It also Sucks Up Mantle Methane !

    "The last entry is early since it is not yet March 2018.

    This shows the ever increasing growth of CO2 levels in our atmosphere.

    Some 2017 figures have shown 410ppm over the year, giving an increase of nearly 1ppm per month."

    Can society even exist in it's current form at 600ppm CO2 concentration ?

    I know the planet has been at that level before, but it took tens of thousands of years to get there and back again, not 250 years.

    Add in the CH4 levels, and you have an equivalence of ~580ppm already." Mark Bevis

    How long before 5 feet of Greenlands 20
    Feet of Sea Level Rise Fukushimatizes us ? 2020 ? 2022 ? ?

    "In the 1990s, the rising sea doubled its previous rate, reaching about an inch a decade, said Sweet. And then, over the past 10 years, tide gauges in Fernandina Beach, Mayport and Key West recorded an increase of about 0.9 centimeters per year, a little more than a third of an inch per year.” James Cox

    Sea Level Rise is accelerating, could just 5 feet of Greenlands 20 feet of Sea Level Rise, melt before 2000, or 2022

    Fukushimatizing US and the World ?

    Greenland Keeps the Northern Hemisphere in Ice and Snow Now.

    From the 1700s to 2000 – 30 percent of the Arctic Melted

    From 2000 to 2015 – 60 percent of the Arctic Melted

    90% of the Arctic is Gone, and what is left is barely any Ice or snow older than 5 years old, and it use to date back Thousands of years, Waxing and Waning in Glaciation.

    Each Day the acceleration of melt continues.
