Deep Bore into Antarctica Ice Shelf Finds Freezing NOT Melting

Of course one could never be aware of that reality based on some very irrational headlines making the rounds. Such as this one: Science Confirms Antarctica is Screwed and So are We!
  Wow, I mean, just wow! We’re screwed and we’re all going to die- FEAR
 And check out the graphics- If the headline didn’t grab you the flaming planet graphic will surely stick in your impressionable mind

Oh my goodness the planet is on fire
Don't tell the people in the UK. Or the people in Rome who just got snow.

We Don’t Want to Scare People But...It’s Cold, Very Cold. Snow. Wind.

Remember the days when the cult of AGW, which rebranded itself to the cult of “Climate Change”, when AGW was a fail, told us all winter was a thing of the past. 
Snow will be just a distant memory... How wrong they were.
Let’s read something more realistic.. National Geographic
Scientists have peered into one of the least-explored swaths of ocean on Earth, a vast region located off the coast of West Antarctica. It is locked beneath a crust of ice larger than Spain and more than 1,000 feet thick, making its waters perpetually dark—and extremely difficult for humans to access. Now, a team of researchers has bored a hole through the ice and sampled the ocean beneath it.

A team of scientists from New Zealand began this two-month expedition in November. A ski-mounted Twin Otter aircraft ferried them 220 miles from the nearest base, landing near the middle of the Ross Ice Shelf—the massive slab of ice and snow, as flat and empty as a prairie, that hangs off the coastline of West Antarctica and floats on the ocean. Amid the glow of 24-hour summer sunlight filtering down through fog, they assembled an automobile-sized contraption of pipes, hoses, and boilers
This machine generated a powerful jet of hot water, which they used to melt two narrow holes, each a few inches across, more than 1,100 feet down to the bottom of the ice. They then lowered cameras and other instruments through the holes, into the waters below. In doing so, they hoped to answer a question of worldwide importance: just how secure is the ice of West Antarctica?
1,100 Feet Down to the Bottom of the Ice. With the sun sun shining 24/7 in Antarctica’s summer season...  They found the ice was growing

"They found the ice was growing"
Surprising Finds

The surprises began almost as soon as a camera was lowered into the first borehole, around December 1. 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
 "Evidence that in this particular place, sea water is actually freezing onto the base of the ice instead of melting it."
"The Ross Ice Shelf “has come and gone probably many times in the last million years,” says Scherer. It likely collapsed during a warm period 400,000 years ago. But he believes it could also have collapsed as recently as 120,000 years ago, the last time that temperatures were about as warm as they are today."
And yet if temperatures were "about as warm as today", 120,000 years ago, why is the Ross Ice Shelf growing? Why hasn’t the Ross Ice Shelf Collapsed? Perhaps it’s not as warm as all the hype?

Ross Shelf Freezing, Not Melting

A report by Popular Mechanics on the study mentions that the hole revealed two unexpected results. One the ice does not seem to be melting, but is freezing and two, the walls of the hole drilled with hot water, which would be really smooth if it was melting, had jagged icy crystals.

Huge snowfall increases over Antarctica could counter sea level rise, scientists say
And insulate the ice from the melting above.. Washington Post

"Based on a more than 500-foot-long ice core extracted from the thick sheet and containing a snowfall record dating back 2,000 years, the researchers found snow accumulation levels had been rising since around 1900. And the increase is most marked in recent decades, up through the year 2010"

    You made me chuckle, Penny. Reminded me of Mary Walsh saying, "Be afraid, eh? Be very afraid." https://www.youtube.com/watch?v=I1IliGODznk
    Especially since I just now quoted a news item on my site saying, "Both countries [Russia & Canada] say they need to work together because thawing Arctic ice will mean greater ship traffic ..." I feel like John Travolta in Welcome Back Kotter: "I'm zo confoozed."

  2. Hey YaYaC:
    Have you seen the icebreakers Russia has present day?
    And the ones they are building- Massive/nuclear powered breakers- monsters really. If I can find something quick..

    There's going to be ice aplenty for bustin' and Russia's got the breakers to do it.

    And they have more on the way...

    when greater traffic is mentioned.. it means for war making: control/denial of shipping and resources- the usual stuff
