UPDATE: Reader ES provides a link shedding more light into the story. Apparently the Aurora Australis broke mooring during a blizzard and ran aground (on ice?) and DID NOT GET TRAPPED IN ICE.

===================================
Schneefan at German skeptic site wobleibtdieerderwaermung.de here writes about how yet another ice-breaker has gotten stuck in summertime Antarctic sea ice.
The Antarctic “Aurora Australis” with 68 people on board became stranded in sea ice in the West Arm in Horseshoe Harbour last Wednesday, and rescue efforts were prevented by a snowstorm. According to reports that the ship’s rump has a tear, but its structural integrity is thought not to be at risk.
For some readers the Aurora Australis may ring a bell. This is because it is the ice breaker that ultimately helped rescue the 52-person crew on board the sea-ice trapped research vessel Akademik Shokalskiy which ferried a global warming/polar ice melt expedition led by a hapless Prof. Chris Turney back in early 2014. That expedition devolved into a highly publicized folly attracting much worldwide ridicule. Eventually a helicopter from the Chinese ice breaker Xue Long succeeded ferrying Turney and his crew to safety.
Today the German Handelsblatt here reports that 37 scientists on board the Aurora Australis were rescued on Friday and that the remaining crew has stayed on board in order to try to free the injured ship.
Schneefan writes that it should be clear to global warming/polar researchers that sea ice at the South Pole is not melting, but has in fact been growing for 37 years!
Arctic sea ice, surrounded by large land masses has, on the other hand, been declining:

Note how the Arctic graph between 1970 and 1980 is missing. Can you guess why?
10 points and a gold star for the right answer.
Yes because satellite monitoring of sea ice began in 1979.
If you wish to troll then at least get your facts half right.
But isn’t growing sea ice a predicted outcome of global warming? (sarc off)
But so is less ice, so is more snow and less snow, more hurricanes and fewer hurricanes, ect. ect. Every thing that happens is attributable to Climate change.

And It may also be remembered from an earlier thread, that the Akademik Shokalskiy is itself classed as an icebreaker.
That German magazine has their story completely wrong. Actually a mooring line broke during a blizzard and the ship got free and grounded on the rocks. This occurred on Feb 24.

You cannot add back radiation to solar radiation and use the total in Stefan Boltzmann calculations to explain the mean surface temperature.
The 324W/m^2 of back radiation is overstated because the wrong emissivity value of the atmosphere has been used in calculating that back radiation from measurements. On Venus, using emissivity of 0.19 for carbon dioxide, the atmosphere would have to be over 350 degrees hotter than the surface for its radiation to support the surface temperature.
Even if you use the 324 figure (as is implied in the energy diagrams which show 168+324-102 = 390W/m^2 into the surface) that 390 figure (being a mean of variable flux) gives you a mean temperature close to zero C, not 15C.
So it’s all totally wrong and the whole radiative forcing greenhouse conjecture fails to explain reality.
If you genuinely want to hear explained what really happens in the equivalent of a 43 minute live presentation, watch the full video as over 1,100 others have done in its first 6 months. You can ask genuine questions on this blog.

Naturally.
Light from the sun (both visible and IR) reaches the earth. What isn’t reflected is absorbed, and causes some warming. The warmed earth emits IR, which is a loss of energy, and so results in COOLING. Some, but not all, of that radiation is scattered back to the earth, re-warming it, but never more than the initial warming. As long as the sun is out, the warming can continue, increasing up to mid day. After that, the heat added by the sun is insufficient to maintain the warming, and a net cooling usually results, especially in dry climates.
So, to repeat, any warming caused by back-radiation will never warm the earth more (usually less) than the degree to which it was initially warmed by the sun, before it radiated heat away. That is why we have cooling at night, because radiation of heat by the earth is ultimately one-way, out to space.
The process is slower when the air is humid and there are clouds, but only slower.

Get ready for expensive batteries – or Tesla losses exploding even more than they do now.
It’s not like they’ve never gotten stuck before. Flashback to October 24, 2012, Springtime in the Antarctic.

Darn it! that pesky sea ice!…. it just won’t do what it is told.
Prof. Chris Turney ..
We have got stuck in the ice, because the ocean warm water sunk to the bottom, pushing the cold ice forming water to the surface ??
Trust me ?? I am a “respected” scientist??
