US Coast Guard Ship To Attempt Rescue of 2 Icebreakers In Antarctica
PolygamousRanchKid writes "A U.S. Coast Guard heavy icebreaker left Australia for Antarctica on Sunday to rescue more than 120 crew members aboard two icebreakers trapped in pack ice near the frozen continent's eastern edge, officials said. The 399-foot cutter, the Polar Star, is responding to a Jan. 3 request from Australia, Russia and China to assist the Russian and Chinese ships because 'there is sufficient concern that the vessels may not be able to free themselves from the ice,' the Coast Guard said in a statement. The Australian Maritime Safety Authority's Rescue Coordination Centre, which oversaw the rescue, said the Polar Star, the Coast Guard's only active heavy polar icebreaker, would take about seven days to reach Commonwealth Bay, depending on weather. Under international conventions observed by most countries, ships' crews are obliged to take part in such rescues and the owners carry the costs."
Coming again, to save the mother fucking day yeah!
Along came an icebreaker and there were...
Two blue ships, stuck upon the ice. Two blue ships, stuck upon the ice, along came an icebreaker and there were...
Three blue ships, stuck upon the ice...
I could have sworn Antarctica only has a northern edge.
In one week will we be reading about how country X is sending an icebreaker to free the three stuck icebreakers?
Good thing it's summer down there. Wouldn't want to be stuck all winter. That would be a pain.
How's that global warming thing working out for you?
You mean, for us? Not so well. Chaotic weather, not even, gradual warming over the entire globe, is what we can expect for quite a number of years.
Don't say that like you're not in the same boat as the rest of us.
An Western European led research vessel gets stuck in the ice. A Chinese ice breaker comes to the rescue. The Chinese ice breaker gets stuck in the ice. A Russian ice breaker with an international crew comes to the rescue. The Russian ice breaker gets stuck in the Ice. Now we have a US Coast Guard ice breaker on the way to save the day. The moral of the story? When you subtract nasty international politics from the equation, we really can get along.

Thank you for yours.
Hell, I remember when I was in grade school in the '90s, and we were constantly told of the horrors of the hole on the ozone layer that was going to burn us to death, and the rain forests that would be 100% destroyed by 1995
They didn't happen because people took measures to mitigate them. The ozone layer was disappearing because of CFCs. Now that we don't use them in spray cans and air conditioners any more the hole is shrinking and should be gone in another 100 years.
You're like the people who scoff at the Y2K Armageddon that didn't happen. It didn't happen because a lot of folks did a lot of hard work to keep it from happening.
Had everyone shrugged and done nothing like you propose with global warming the ozone would still be disappearing and the Y2K meltdown would have been serious.
Free Martian Whores!
Umm, yes we do.
Lake Superior, for example, sometimes has 6 to 12 feet of ice, and the Coast Guard opens channels in the spring for shipping to proceed as early in the season as possible.
There can be ice around Alaska coastline as well, and Coast Guard resources are used to free stuck ships.
There are some complex facts that usually don't get dragged into this discussion because they make it so much larger. But some interesting facts to color the warming issue are:
1. We are currently in an ice age. The current Quaternary glaciation (i.e., the current ice age) started 2.5 million years ago.
2. Within that ice age, we are in an interglacial: a period of temporary(?) warming within the ice age. Our current interglacial is the Holocene epoch, which started 11,700 years ago.
But as long as we still have ice caps, we are still in an ice age. If the ice caps melt, we'll know the ice age is over and we're back to what is in fact more normal temperatures for Earth.
However, it can't be said that Earth's normal warm is necessarily good for humanity. After all,
3. Humans, as in the genus Homo, evolved around 2.5 million years ago. The same time as the the beginning of the current ice age. In other words, the adversity of the Earth's freezing put heavy evolutionary pressure on our ape ancestors.
So, cold = good? Well, remember the current interglacial started 11,700 years ago. Now that's interesting. The Old Stone Age begins with the first humans, that ~2.5 million years ago. But...
4. The Middle Stone Age started right around when the interglacial started. That's when humans first began to make more advanced tools, create advanced art, develop spirituality, etc. In other words, when things warmed up a bit, humanity began to flourish.
So what's good? Warm, cold, in-between? What's "natural?" 'Cause that seems to be extremely warm... unless you're talking about humans, then it's extremely cold. Or moderate.
Complex, eh?
Now, apart from global warming, the related issue that always gets short shrift is ocean acidification, which is also caused by an abundance of CO2 in the atmosphere, and which appears to be a huge threat to life on Earth. But it's harder to understand than warming, so let's not talk about it.
At least in principle. The exact details of *weather* are always complex.
Here's a link to an article explaining where the ice in question comes from:
“There's a misconception here – we are not trapped in new ice that's been created because its cold,” said Turney. “This is very old, thick ice that's been re-mobilised. It was attached to another part of the continent and has broken out and, with the south-easterly winds we've had, has pushed it up against the coast and pinned us in.”
The austral sea ice situation is complicated by the fact there's a continent down there and it's not perfectly round. It sticks out into the sea in irregular ways. This means that the extent of sea ice (which is present year round) is dependent on the wind, which in turn is stronger with a more energetic (warmer) atmosphere.
