Antarctic sea ice growing – What the heck is with this double talk????

“I can’t figure out what the heck this writer is saying,” says reader. “What does this mean?”

“In Southern Hemisphere winter months, ice extent has increased by around one percent per decade. In the summer, ice has increased by two to three percent per decade, but the variation is larger than the trend.”

and then this:

“….. average Antarctic sea ice extent has stayed the same or even grown slightly.”

and then throws in this:

“These continental ice areas are shrinking and therefore contributing to sea level rise. Stammerjohn said, “Though it is true that, on average, Antarctic sea ice is not changing, or even slightly increasing, the overall average hides a very large regional decrease that could have global consequences.”

ice melting is causing the sea’s to rise but Antarctica’s ice is actually growing? it’s the melting causing the rise in sea levels as the ice increases on average by 1% in winter and 2-3% in summer per decade??? ….what am I saying…what am I reading???

Robert, what’s going on here?

Hi Jason,

Three of their sentences pretty much tell the story.

  1. “Overall, Antarctic sea ice has grown slightly over the past thirty years.”
  2. “In Southern Hemisphere winter months, ice extent has increased by around one percent per decade.”
  3. “In the summer, ice has increased by two to three percent per decade.”

I think the rest of the words are designed to cover that up. You’re not nearly as confused as they’d like you to be.

  1. Melting or growing sea ice has no impact on sea level in the world. You can test that by floating an ice cube in a measuring container.

    So growing antarctic sea ice does not change sea level

    But ice at the shore is not floating so when it melts it adds water to the ocean and sea levels rise.

    So melting continental or shore fast ice causes sea level to rise

    • Agreed, but of course, if the sea ice is growing, so is the land ice, since it is not sitting on potentially warmer water, as is the sea ice. Net results, the water level is going down – Wait!! That’s exactly what is happening, isn’t it? Sneaky how those warmists can have both cold and hot caused by global warming, thus both rising and lowering sea levels can also be caused by global warming! Next time they have their paper signing in the Maldives, they may need oxygen because they are too high in the sky instead of doing it underwater.

    • Provided that the experiment runs like this: take a measured amount of water, 4 liters, and have a 4 liter container,freeze 1 liter, then add it to the water. You will note that the water level rises while the ice is frozen owing to displacement, but goes to equilibrium when it melts. The other effect is thermal, same experiment, but the water is hot,same results as above, but the water chills down very quickly.

    • shore fast ice is sea ice, this will not raise or lower water levels, as per your experment, it’s the Iceshelf or Glacier ice melting that will raise the levels, they are fresh water

  2. I had debated creating a 15 step convoluted process to show how warming created more ice, but gave up. I am getting too old for this nonsense. Simple fact is that there is more ice because things are getting cooler not warmer. Occam’s razor applies here as everywhere else in life.

  3. Fact is, that 2012 has started with the (arctic + antarctic) sea ice extent above the long-term average. Only by 0.1 – 0.2m sqkm, to be sure.

    But it does say that the situation is pretty normal, doesn’t it?

    Pay no attention to that man behind the curtain, do as we say, believe what we tell you.
    These aren’t the droids you’re looking for…
