Time to take a quick look at the sea ice situation down under, as I must have missed it on BBC News!

According to NSIDC, a new record high has been set for April, beating last year. Ice is above average virtually all around the continent.

    Arctic not looking bad either

    The real issue with the Antarctic ice growing is we are now closer to the sun and more sun shine will be reflected and thus some heat loss will happen.

    Radio 4 Today programme sounded like a party political broadcast for the Greens this morning. A Norwegian team is apparently for the first time (in history) recording ice levels in the Arctic during the winter; the shrinkage there (of course); and the danger that this situation presents to the microscopic sea-life that forms the diet for the animals thereabouts. It too is reducing. They also had (is this news?) a report on the climate conference which is to take place in France later this year.

    The ice in the Arctic is increasing due to the negative change of AMO.
    “The PIOMAS project attempts to measure the “volume” of the arctic sea-ice. This is difficult and has been an elusive piece of data to obtain, and the PIOIMAS project is critisized for various reasons, but likely is our best attempt so far. I find the above graph interesting for it suggests the sea-ice has been thickening the past few years. (The current year is the red line.)

    Of course, “average thickness” is a bit of a ridiculous concept, as the thickness of the ice varies greatly. The Laptev Sea, which exports a lot of ice due to winds howling off shore from Siberia, can have open water when it is -40°, and often has only a skim of ice less than a foot thick which will melt easily in the summer sunshine, but all that exported sea-ice tends to be carried by cross-polar flow and crunch up against the north coast of Canada, where the ice can be twenty feet thick.”

    “April 24, 2015 — I believe in one of my first blog posts I mentioned that we were working in an area of high accumulation (snowfall) on the Greenland Ice Sheet. I would like to change that to an area of VERY HIGH accumulation! Actually Southeast Greenland does receive the largest amount of snowfall on the entire ice sheet. In previous years we have experienced storms dumping over a meter of snow. This year we had one of those storms bringing well over a meter of snow and then 3 hours after the first storm ended we got a second, bigger storm, pushing our 5 days snow total to nearly 3 meters of snow.
    The amount of snow is best summed up by a dinner conversation in our cook tent where Olivia, being on the ice sheet for the first time, asked Clem, Josh and I, ice sheet veterans, what the biggest storm we had ever been in was like. We all responded, in unison,” this is the biggest storm we have ever been in!” While the weather was not particularly cold or windy, it just kept snowing. The low wind made it possible for us to continue science measurements through the storm in a special tent, with no floor, providing both shelter and access to the snow.”

    Please see the temperture in the North Atlantic.

    The ‘charctic’ interactive graph makes the Arctic sea ice look lower this year.

    This is the Danish Met Institute version ( note: mean value is 1979 – 2000 only).

  7. Richard111 says:

    I saw the BBC program mentioned by Roger Gough above. Shadows indicated film was recorded in high summer. Someone did mention sea currents, gosh and golly! Annual sea ice is only about a metre thick. Try to imagine a few thousand square KILOMETRES of ice with the supporting sea underneath on the move. Of course it will show spectacular breaks! Yet the program implied this was due to ‘climate change’! Sheesh!

    Just found this…

    Lots of juicy comments on the BBC performance.

    Well, regarding the Antarctic sea ice, it takes 200 years for Antarctica to notice what’s happening in the North http://www.realclimate.org/index.php/archives/2015/04/how-long-does-it-take-antarctica/

    I guess that Antarctica recently noticed the Tambora eruption and “the year without summer”🙂

    [reply] the 200 years only applies to ‘abrupt climate events’ which rarely occur

    NEWPORT, Ore. – Axial Seamount, an active underwater volcano located about 300 miles off the coast of Oregon and Washington, appears to be erupting – after two scientists had forecast that such an event would take place there in 2015.

    Geologists Bill Chadwick of Oregon State University and Scott Nooner of the University of North Carolina Wilmington made their forecast last September during a public lecture and followed it up with blog posts and a reiteration of their forecast just last week at a scientific workshop.

    They based their forecast on some of their previous research – funded by the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration (NOAA), which showed how the volcano inflates and deflates like a balloon in a repeatable pattern as it responds to magma being fed into the seamount.

    Since last Friday, the region has experienced thousands of tiny earthquakes – a sign that magma is moving toward the surface – and the seafloor dropped by 2.4 meters, or nearly eight feet, also a sign of magma being withdrawn from a reservoir beneath the summit. Instrumentation recording the activity is part of the NSF-funded Ocean Observatories Initiative. William Wilcock of the University of Washington first observed the earthquakes.

    It is known (SWARM) that the magnetic field is very strong on the Indian Ocean. You can see it in the decomposition of ozone in the southern hemisphere.

  14. Paul Vaughan says:

    ren, what is the software the narrator is using in that video (May 5, 2015 at 3:38 pm) to show the earthquakes? do you have a link to the hub from which that character operates? quite colorful – if people hang in past the slow start to that video, I think they’ll get interested in the topics covered later in the video. True or even if not true, the idea that the mainstream media is not warning the public that the whole pacific plate is moving will resonate with people who like to back a underdog alternative to dull mainstream administration’s slow crawl to almost nowhere. Even if the guy is completely wrong about everything, his enthusiasm will encourage bright people to take an interest in the problem and explore …and I’ve no doubt whatsoever that there are countless brilliant amateurs all around the world who would kick dull mainstream’s *ss big-time given the time & the resources to issue such a blow to the snail-paced incrementalism of centralized inefficiency.

    April 24, 2015 – Intrusion / eruption (?) event at Axial Seamount
    There was a major seismic/deformation event at Axial Seamount on 23-24 April 2015. Thousands of earthquakes and sudden ground deformation (subsidence of 2.4 m over the first 3 days) were detected by the instruments on the OOI Cabled Array. The event definitely involved an intrusion of magma into the upper south rift zone (probably a dike), but it is not yet clear if there was also an eruption of lava onto the seafloor. Apparently, no lava was erupted in the summit caldera where the OOI cabled observatory instruments are located, because they all survived and there are no obvious temperature anomalies (yet). It’s still possible that lava erupted either north or south of the caldera along one of the rift zones, but we won’t know if that happened until a ship can get out there to look (probably not until late May at the earliest, but definitely by mid-July). Real-time seismic data from the OOI cabled observatory are being posted by William Wilcock here, and bottom pressure/tilt data are being posted here. There was an Axial Seamount science planning workshop 20-22 April in Seattle and the meeting web site has more information about this event. This is the event that we forecast last fall to occur sometime in 2015, so it’s very exciting that it actually happened! We will have an expedition to Axial in mid-August to repeat our campaign-style pressure measurements to update the time-series below.

    After a strong flare X and the expected magnetic storms can be expected again crustal movements. As we wrote dangerous are strong spikes in magnetic storms.
    Paul Vaughan this may be the end of a long cycle. This shows the Sun’s magnetic field.

    I agree with what you say, and I wanted to ask ren the same question.

    Yo ren!!!!!!!

    News report: ‘Record Antarctic sea ice a logistic problem for scientists

    ‘Growing sea ice surrounding Antarctica could prompt scientists to consider relocating research stations on the continent, according to the operations manager of the Australian Antarctic Division.

    Rob Wooding said that resupplying Australia’s Mawson Station — the longest continuously operated outpost in Antarctica — relied on access to a bay, a task increasingly complicated by sea ice blocking the way.’

    Just a blip obviously😉
