   A website I found that is really interesting helps with the idea of size.

   Antarctica is big – but not as huge as maps would have us believe.

   The site is a lot of fun to play around with.

     Depends which maps you’re using. Mercator makes it look giant. Actual globes give you both its real shape and size, but there are also other 2d projections that don’t glom Antarctica into a big mass in order to preserve straight latitude and longitude lines at the same time. (that is to say, the traditional map you’re thinking of that that site uses is made for sailing)

     It’s bigger in current area than Australia and New Zealand put together, although might not be post-melt?

     That’s right James;

     Just make fun of the true seriousness of the catastrophe we are facing as you appear to be yet another dumb climate change denier.

   Antarctica is far more beautiful than people realise.

   Loyd Homer (GNS photographer) did these amazing shots about 20+ years ago. I’m telling you it looked like National Geographic stuff. Haven’t seen them since.

   Would be nice to see some before and after shots if only to wake everyone up.

   Thanks Bill that information relieves my conscious somewhat.

   ( The thickness of the ice covering Western Antarctic is up to 2000m or 2 km thick ).

   Here I was thinking for the last 10 years catastrophe coming !
   Cripes ! that ice is 2000 meters thick. ( Thinking thats not going to melt )

   It would take Genzebe Dibaba to run the women world record for 2000m : 5:23.75 , 2/7/2017

   Here I thought it can’t be many years now and we will have a loverly beach 100 meters from home.
   My home’s altitude is 50 meters.

   But thats not going to happen.
   So I am over climate change, our climate here in Dunedin has nearly changed every year that I have been alive 1950.

   I must go fill my carbon burning beast and drive many kilometres before the Gov’t stops importing oil products.
   Meantime I will enjoy life and leave it to my 30 odd year generations later down the track deal with it.
   I am sure they will be well educated and free from fees etc to do that.

     Yawn.

     I really wish people would read and comprehend before commenting.

     If an ice cliff cannot be higher than 100m before losing its physical integrity, what do you think happens when the edge of the ice is being asked to soar 1km into the air, or 2 km into the air, or even 300m into the air?

     You think it melts?!

     It collapses. And the geology of WAIS sits below water.

     What amount of water gets displaced by floating ice, and what difference does it make whether that floating ice melts or not?
     • Matthew Whitehead 5.1.1

       13 April 2018 at 5:24 pm

       Also, in addition to water displacement as more of the ice moves into the water, post-collapse it will have absolutely increased the exposed surface area of the ice, which combined with temperature, (we’ve already sorted that increasing for both air and water with global warming) is what determines melt speed, (and collapsed ice WILL melt so long as there’s a reasonable chance it moves northward) so it will lead to a sharp initial rise in sea levels that Bill notes, plus a slower rise (but still faster than models that hadn’t factored in collapse) as the melting accelerates from more of the ice touching warmer air or water instead of other ice.

       As Bill notes in the post, this isn’t catastrophizing, it’s models being refined to better reflect real-world physics.

         13 April 2018 at 5:35 pm

         The air temperature in Antarctica, unlike in the Arctic, isn’t really increasing – the libido effect of the continent is intact.

         Antarctica (West Antarctica) is being “taken out” from below by warmer ocean temperatures, not warmer air temperatures.

         And since the West Antarctic Ice Sheet is grounded well below the water line, and because the ground slopes down and back away from where the ice is presently resting on bed rock, it means that processes of disintegration won’t stop and worse, will accelerate.

         edit – I just found it useful to conceptualise the collapse in terms of everything that we have currently built (and then some), falling down. It makes more sense to me than talking of gigatonnes and what not.

           The mean annual air temperature of the Antarctic Peninsula has increased by nearly 3°C in the region in the last 50 years, (about 10 times faster than the average for the rest of the world) the only comparable regions are in the Arctic. The temperature of the rest of Antarctica shows indications of rising at a slower rate.
           The surface of the ice sheet at the South Pole is more than 9,000 feet in elevation–more than a mile and a half above sea level. The warmest temperature recorded at the South Pole (which is not the coldest place on Earth) was −12.3 °C on Christmas day 2011. The coldest temperature recorded on Earth was −89.2 °C at Vostok Station in July 1983.

             “the libido effect of the continent is intact.” Gives new meaning to the saying, hard as ice! And it appears that on this day, Friday the 13th April, we’ve just shattered the ‘coldest temperature recorded on Earth’ as Dome Fuji / Valkyrie sunk to -96˚C (just checked again now and it’s ‘warmed up’ to only -92C but hey, it’s still a record and it’s only autumn…).

             http://amrc.ssec.wisc.edu/data/view-data.php?action=view_image&product=surface/plot/TAC.GIF

             Australia’s BoM was recording -55˚C at B*mbala in NSW today too (so I don’t set-off trigger warnings, replace the *asterisk* with an ‘o’). Either automated weather stations have gone wonky en masse or it’s freakin’ cold out there! And don’t mention the hundreds of live volcanoes simmering and oozing and bubbling away under both the West Antarctic Ice Shelf (sea ice) and Sheet (land ice).

             Keep the home fires burnin’ – she be mighty chilly out thar tonight.

               With Global Warming (ie Increasing energy being trapped in the troposphere due to increasing GHG’s) we should expect widely varying changes in weather – such as we have just witnessed in NZ). As sea temperatures rise and fall, pressure zones and depressions increase in intensity, with higher winds, Higher air temperatures in warmer climates also means the air holds more water vapour to be transported to colder regions – such as Antarctica – to be dropped as snow. As you see – even though the Antarctic Peninsula has warmed by 3°C it is still below freezing. So the warm, moisture filled winds, blowing south from the Pacific, Atlantic, and Indian Oceans will increase the snow burden on the Continent.

               Imagine a pot of cold water on a stove. As you turn on the element and add energy to the water, the water doesn’t heat up uniformly – convection currents swirl around, making some parts cooler, some parts warmer than others. Essentially our planet is going through the same process.

   I read an article some 3 or 4 years ago where a couple of scientists had evidence that led them to conclude the west antarctic ice sheet had collapsed in a matter of months last time…..despite extensive searching I have been unable to refind the article but clearly recall the impression it made.

   “So when I hear that the West Antarctic Ice Sheet is melting…”

   Source please.

   Personally I’m finding more and more scientific studies and accounts concluding the opposite, i.e. that they’re in fact finding MORE ice developing on existing shelves and that it’s been cooling over the last century.

   ““The annual mean temperature has decreased at a statistically significant rate, with the most rapid cooling during the Austral summer.”
   – Turner, et al. (2016) https://www.nature.com/articles/nature18645

   “(a) there has been no overall warming trend for large portions of the continent in the past few hundred years, (b) the Southern Ocean has been cooling since 1979, and that (c), because of the cooling ocean, sea ice extent has been advancing.”
   – Jones et al. (2016) https://www.nature.com/articles/nclimate3103

   “(1) Temperatures over the Antarctic continent show an overall cooling trend during the period from 0 to 1900 CE, which appears strongest in West Antarctica, and (2) no continent-scale warming of Antarctic temperature is evident in the last century.”
   – Stenni et al. (2017) https://www.clim-past-discuss.net/cp-2017-40/cp-2017-40.pdf

   “During 2003 to 2008, the mass gain of the Antarctic ice sheet from snow accumulation exceeded the mass loss from ice discharge by 49 Gtlyr (2.5% of input), as derived from ICESat laser measurements of elevation change. ”
   – Zwally, et al. (2012) https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20120013495.pdf + https://vimeo.com/46429608

   “The undersides of ice shelves are usually smooth due to gradual melting. But as the camera passed through the bottom of the hole, it showed the underside of the ice adorned with a glittering layer of flat ice crystals—like a jumble of snowflakes—evidence that in this particular place, sea water is actually freezing onto the base of the ice instead of melting it. ‘It blew our minds,’ says Christina Hulbe, a glaciologist from the University of Otago in New Zealand, who co-led the expedition.”

     How’s about you simply read the linked paper from the post, or alternatively, look up any other damned peer reviewed scientific paper on the matter?

     And while you’re at it, educate yourself on the difference between an ice shelf and an ice sheet. (Hint: one sits on water, while the other is grounded)

   Today this is our submission to the ‘Climate change panel’ chair after their release today of the ‘Climate Change Minister James Shaw’ says he’s been impressed by the enthusiasm and leadership shown by the financial and business sector at the launch of a new “Climate Finance Landscape Report” in Auckland.
   “The transition to a net zero emissions economy brings huge opportunities and the finance sector has a significant role to play making it happen.

   Protecting our environment & health.
   In association with other Community Groups, NHTCF and all Government Agencies since 2001.
   Public COMMUNITY submission to;

   Hon; James Shaw. – Climate Change Minister.

   13th April 2018.

   Dear James;

   • PLEASE RECEIVE & CONSIDER OUR SUBMISSION/POSITION ON REDUCING GREENHOUSE GASSES AND POLLUTION THAT ARE CAUSING CLIMATE CHANGE AND ENVIRONMENTAL DAMAGE. NOTE; THIS IS STILL THE SAME IN 2018 AS IT WAS IN 2001. (See below our 2001 Submission to the then Climate Change program as it was then called. )

   • Our NGO has a long history of standing up for the Environment equal to anyone else and seen three Government changes since.

   • WE SENT OUR SUBMISSION IN 2001 TO THE ‘THEN MINISTER FOR CLIMATE CHANGE’ AND IS NOW AGAIN OUR SUBMISSION TO THE NEW MINISTER FOR CLIMATE CHANGE Hon’ James Shaw at his “launch of a newClimate Finance Landscape Report in Auckland. (See our submission below as then in 2001 was addressed to Martin Harvey, Deputy Director 7th November 2001 NZ Climate Change Program)

   • Please use Kiwirail in place of Tranzrail in our new submission please as the direction has been the same lack of quote; taking any action on “economic opportunities arising from taking action on climate change.”

   Thank you for your attention.
   We anticipate your response.
   Secretary.

   Press Release: New Zealand Government
   Hon JAMES SHAW
   Minister for Climate Change
   13 April 2018
   Key financial, business and environmental leaders meet to talk financing climate action
   Key leaders from the finance, business, environment, church, government and academic communities met today to discuss economic opportunities arising from taking action on climate change.
   Climate Change Minister James Shaw says he’s been impressed by the enthusiasm and leadership shown by the financial and business sector at the launch of a newClimate Finance Landscape Report in Auckland.
   “The transition to a net zero emissions economy brings huge opportunities and the finance sector has a significant role to play making it happen.
   “The Government is already working on several of the report’s recommendations, including establishing a Green Investment Fund, fixing the Emissions Trading Scheme to provide effective carbon pricing, and I have asked officials to look at options for disclosure and reporting of climate-related financial risks,” says James Shaw.
   “New Zealand has committed to making sure finance flows go towards low emissions and climate resilient development as part of the Paris Agreement,” says Mr Shaw.
   A report by economic research collective, Mōhio, commissioned by the Ministry for the Environment, confirms there are multiple opportunities for financial institutions and companies to take action to lower emissions – and many are already leading the way.
   “Many businesses and investors can see that climate action and green activities are not only good for business – but are a crucial part of New Zealand achieving a low emissions, climate resilient future, while also reducing risks to the financial sector.
   “Financing the clean economy is crucial to ensuring a just transition that creates jobs in new industries.
   “Roughly two thirds of all climate finance globally comes from the private sector, so there is heavy reliance on them to take action.
   “Climate finance activities are underway, progress is being made, but this is just the start of a long journey and we need to do more. We need to build on existing leadership and momentum.”

   OUR POSITION ON REDUCING GREENHOUSE GASSES AND POLLUTION THAT ARE CAUSING CLIMATE CHANGE AND ENVIRONMENTAL DAMAGE

   Local Councils face a major task of lowering the adverse effects of heavy truck noise and pollution all over Napier; trucks are now operating through Napier 24 hours a day, which is creating stress and adverse health effects to residents.

   The answer lies in rail. The re-establishment of rail freight through Napier to the port and other regions would heavily reduce this massive overuse of heavy trucks to move our region’s exports and imports. We obtained LTSA records which confirm our worst fears that during the 1990s there was a large increase of freight trucks on our roads while rail freight declined, as a result of road transport deregulation. It is well proven that when more roads are built, the traffic increases in proportion. We believe a new transport strategy needs to be developed, both by local and government authorities, that reflect a commitment to support more rail freight rather than road freight alone.

   We received the following attached information that Tranzrail is now beginning to dramatically reduce it’s freight wagon fleet that they perceive as no longer part of their core business, and that they are sending 100s of wagons to the scrap yard to be scrapped, including log hauling wagons, flat deck container wagons, fertilizer, fuel, tallow and resin tankers, and much more. We called Sims Pacific Metals at (09) 276 1809 and it was confirmed to us that they have already recently destroyed 100 of the first 300 wagons Tranzrail has sent them on contract to destroy. It seems that this present ‘get rid of’ mentality is more business ideology driven than based on sound engineering principles. Deliberate wrecking of rail infrastructure that is part of essential services could destabilize this country if another fuel crisis or economic recession occurs.

   According to UK reports, pollution from road transport networks is very damaging to the environment and to human health. Transporting one tonne a distance of one kilometre by road produces fumes totalling 72g of carbon dioxide as opposed to 7.5g for rail, and 0.1 particles as opposed to 0.01g for rail. In simple terms, trucks pollute 10 times more than trains. The report also confirms that a large truck causes 100,000 times more damage to roads than a car, and the cost of road maintenance is unfairly paid by car operators, not truck operators.

   Tranzrail’s ominous new direction is a matter of great concern, that valuable rolling stock is being destroyed when they should be retained by us for future freight handling by rail. Tranzrail is now the largest trucking company in New Zealand, and must be required to return its freight back to its rail system that it bought for that purpose in the first place, with some form of incentive from government for the benefit of the environment.

   Investment in the rail will pay in the long term, and if the economic reason to do so is not obvious to us now, we must do it for the environment, to help the planet, to reduce the carbon dioxide and the greenhouse gasses. Lateral thinking is what is needed now. Simply, if we are to seriously concern ourselves with the long term effects of climate change, we must start now reducing our dependency on heavy truck freight hauling and return to the more environmentally friendly rail freight system, as most of our trading partners are doing.

   CEAC Inc has researched the rail issue and has extensive information to share. We look forward to presenting our views in the future, when local and central government are working on transport strategies, to which we would like to be involved. If you have any questions, please do not hesitate to contact us.

   Yours truly,

   CEAC.

       “The polluting effect of wear and tear in brakes and tyres”

       Some wear-particles from brakes and tyres are small enough to be inhaled, and the increase in wear-particles can outweigh the benefits of improvements in exhaust emissions

       Gary Fuller @drgaryfuller
       Sun 11 Sep 2016 21.30 BST Last modified on Wed 14 Feb 2018 16.36 GMT

       The harder the braking, the more particles fly – a driver brakes during the Italian Formula One Grand Prix on 4 September, 2016.

       One in six MOT failures is due to brake or tyre problems. These wear as we drive, as does the surface of roads. Most of the wear material ends up as dust at the kerb or gets washed into drains but some wear-particles are small enough to be inhaled, and contribute to our air pollution. These particles are rich in transition metals which add to the toxicity of our urban air.

       Increasing amounts of wear-particles have been found in new research from King’s College London. Scientists tracked air pollution alongside 65 roads for ten years. The researchers found some roads where the air pollution benefits from improvements in diesel exhausts were outweighed by increases in particles that come from the wear of tyres, brakes and the road. This was mainly on outer London roads that had increasing numbers of heavy good vehicles.

       Calls for a new clean air act in the UK

       Accessories such as electric windows and air conditioning mean that new cars can be heavier than the ones that they replace . This means more brake and tyre wear. Brake systems on cars, vans and lorries have also changed. Since disc brakes have been gradually replacing drum systems, but open discs emit more inhalable air pollution than drum brakes, where the wear-particles are mostly sealed in.

       There are no policies to control these emissions. Stopping from 30mph emits around twice the amount of brake particles compared with stopping from 20mph, so lower urban speed limits could help, as could reducing traffic volumes – especially by better management of goods moved by road.

    In reality Antarctica is about the size of Australia. Which is still fuckin big, but not massively amazingly enormous..

    It seems a Kiwi research team have recently discovered west Antarctica ice sheet is actually freezing underwater so no immediate worry about catastrophic sea level rise from melting ice?.. https://news.nationalgeographic.com/2018/02/ross-ice-shelf-bore-antarctica-freezing/

    Nasa says that areas of ice are melting at an accelerated rate due to underwater thermal volcanic activity.

      2. What has that link got to do with retreating ground lines?

      3. Where in the post is there any mention of East Antarctica? And what possible effect could any “balance” of gain and loss in East Antarctica have on the West Antarctic Ice Sheet?

      And an additional – what makes you think that what can be observed on the surface gives any indication whatsoever of what is happening hundreds of metres beneath the ocean’s surface?

        Whoa… defensive much?

        1. I was just reading what the experts were saying in the articles. They were just the first few links that popped up in a search about antarctic ice melting.. I dunno as don’t take much interest in the subject, but would imagine that if massive ice shelves which are currently supported by rock (the ground) break off and / or melt into the ocean they would cause some sort of sea level rise?

        2. Fucked if I know, I was just posting some articles about Antarctica and it’s current state which I found interesting, especially with Kiwi scientists out in the wickedly hard core environment doing their science thing. Those guys are the real deal!

        3. See 2.

        The additional – Hey, I have an answer for that one! The Kiwi research team drilled through 1km of ice and were taking readings from under the ice sheet.. so there!

        Aww just figured it… you’re pissed coz it turns out Antarctica’s not that massive aye? All good, it’s still the highest, coldest, windiest and for many months the darkest place on the planet! See, I never would have learned this stuff If you hadn’t posted your article, now I might even endeavor to learn a bit more as it’s quite a freaky place really…

          Read the natgeo article again. They were drilling under the Ross ice shelf.

          The ice shelf is important because:

          The West Antarctic Ice Sheet is up to 10,000 feet thick in some places. It sits in a broad, low bowl that dips thousands of feet below sea level—making it vulnerable to deep, warm ocean currents that are already nipping at its outer edges. It is stabilized, at least for the time being, by a phalanx of floating ice shelves, that hang off its outer edges—of which the Ross Ice Shelf is by far the largest. Those floating shelves provide a buttress; they “are holding back a very big amount of ice,” says Craig Stevens, an oceanographer from the National Institute of Water and Atmospheric Research in New Zealand, who participated in the expedition.

          Funny thing about those volcanos, too. One theory suggests that the weight of the ice sheet is suppressing some of the volcanic activity. If that weight lessens, the activity increases, and more of the ice sheet melts.

          So the worry is that the loss of buttressing ice shelves causes a feedback loop of increasing calving and melting causing more volcanism and therefore accelerated melting again.

    I suppose if your a penguin, whale or seal its great ! My sons got a mate who works on a fishing vessel near the Auckland Islands… 3 months aboard.. Brrrrr !

    No thanks.

    And besides – its full of Nazis and aliens ! Mwhahaha !

    Whereas it has been suggested that such a colossal amount of ice would take thousands of years to melt down (as though we were talking of some big ice cube just melting off into the ground), when researchers take processes like “ice cliff failure” (max possible height for an ice cliff being about 100m) and hydro-facturing – (think water and crevasses) – and factor them into modeling, then the collapse of the West Antarctica Ice Sheet occurs over decades, not centuries, and certainly not thousands of years.

    And yet we are still allowing oil and gas drilling up to 2050 and exploration for new reserves up to 2030.

    And New Zealand’s greenhouse gas emissions keep relentlessly going up, year after year, just as they have under the last two or three administrations. And that continuing increase does not look likely to change under this administration.

    And we keep opening up new coal mines.

    What the hell is that all about?

    Small potatoes you may say, as New Zealand’s greenhouse emissions, (from all sources), totals only 0.2% of the world total. And what we do hardly makes any difference at all.

    However, as Professor Gluckman has said, New Zealand’s biggest contribution to stopping climate change will be by doing something iconic, something that will make the world sit up and take notice.

    In my personal meetings with politicians, all of them agree (on both sides of the house, with varying levels of shock and awe), that canceling oil exploration licences would most certainly be that iconic event that would capture the world’s attention.

    Greenpeace Aotearoa latest petition calls for just that.

    Oh, and also, the repeal of the Andarko Amendment so that we can mobilise the sort of protests that will make oil exploration impossible and too expensive to continue with.

    Hi Bill thanks for the article it is very timely.

    Also another stark reminder for us was the fact that successive studies have also found that black tyre dust was detected being swept up of the atlantic currents and was depositing on the ice shelves and attracting heat from the sun and increasing the melting of the ice caps.

    So increased car/truck tyre dust will increase ice shelf melting.

    Climate change: How do we know?

    Now the average heavy freight truck has 34 tyres and produces 100 times more tyre/brake dust and exhaust soot pollution than one car. (NIWA statistics)
    Latest scientific evidence shows these forms of black dust are accelerating the melting of arctic ice faster than previously thought.
    This is increasing sea level rise far more quickly than before.
    This is why we need rail freight transport.
    This is not time to plan more truck routes.
    The proof is here – Quote; “Global sea level rose about 17 centimeters (6.7 inches) in the last century.
    The rate in the last decade, however, is nearly double that of the last century.We don’t need more roads for trucks we need a return of rail services.

    We need to manage our transport to lower the air pollution that will increase Antarctic ice melt.

    The evidence for rapid climate change is compelling:

    Sea level rise

    Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century

      A ship emits at least 30 times less carbon per ton km, than trucks.
      Just saying.
