Circumnavigating the Arctic Ocean

It's not often possible to circumnavigate the Arctic Ocean but this year two expeditions are hopeful of doing so -- the Norwegian explorer Borge Ousland and the Peter I yacht from Russia.
Their task looks possible because average ice extent for August was 5.98 million square kilometers (2.31 million square miles), 1.69 million square kilometers (653,000 square miles) below the 1979 to 2000 average, but 620,000 square kilometers (240,000 square miles) above the average for August 2007, the lowest August in the satellite record. Ice extent remained below the 1979 to 2000 average everywhere except in the East Greenland Sea near Svalbard.

The graph above shows daily Arctic sea ice extent as of September 6, 2010, along with daily ice extents for years with the four lowest minimum extents.
The solid light blue line indicates 2010; orange shows 2009, pink shows 2008; dashed green shows 2007; light green shows 2005; and solid gray indicates average extent from 1979 to 2000. The gray area around the average line shows the two standard deviation range of the data.

Is Scott Morrison getting ahead of Malcolm Turnbull in the GST debate?

Image
Michelle Grattan , University of Canberra Scott Morrison has become a true believer in the cause of raising the GST, determined to drive a major switch in the tax mix. The big question is whether Malcolm Turnbull will end up in the same place as his treasurer. Turnbull is keeping his options open. “Changes to the GST are certainly part of the tax debate and certainly being actively considered by the government,” he said on Friday. If Turnbull agrees with Morrison, all will be well and good between them. On the other hand if Turnbull eventually opts for caution and doesn’t walk down the GST road, or in the shorter term feels Morrison is getting ahead of the game, that would be awkward for the gung-ho minister, who would the need to manage his retreat. Morrison wants a high profile and he seeks the limelight. But that carries risks. There is always that salutary tale from Labor days. Paul Keating was passionate about introducing a broad-based consumption tax. Bob Hawke let

A politician under considerable pressure. Looking for a way out and not being able to see it. Hansard tells the story of how it came about: Members of Parliament: Staff  Mr ALBANESE (Grayndler—Leader of the Opposition) (14:33): My question is to the Prime Minister. Thirty days ago, the Prime Minister told this House that he asked his former chief of staff, one of the few people he's ever shown empathy for, to verify what his office knew about the reported sexual assault of Brittany Higgins only metres from where he works. Mr Gaetjens reported his findings on the Prime Minister's sports rorts within two weeks. Why is this report, about the Prime Minister's staff, taking so long, and will the Prime Minister release this

Making a mockery of Labor Party pre-selections

  The shenanigans of the SA branch of the Labor Party just gets worse and worse. The Federal Executive of the Party should intervene to stop this madness. What follows is a post I received this evening from my friend Maggie Dawkins about her daughter Alice's courageous decision to take on the power brokers and seek preselection for the seat of Spence. "Alice innocently exercised her right as an ordinary member of the Labor Party to nominate for Spence. What she may inadvertently have stumbled upon is a done deal agreed to by faceless power brokers of the Left and Right factions. Ordinary members have not been consulted, but it is all leaking out as Alice calls the SA Party office to account. It appears that many members may not be comfortable with this done deal, as they are contacting me, not only as Alice’s mum, but also as a board member of Whistle Blowers Australia. Is the deal correct? Who knows? Perhaps time will tell? We know that some of it is correct, for example, Ni
