Rate Of Sea Ice Expansion Increased Five-Fold In 2000 -- CosmosMagazine July 5, 2016

On July 2, 2016, I posted:
Everyone now agrees that we're experiencing or will experience a "protracted solar minimum" which means a drop in energy reaching the earth.

But a German science institute says the effects of that "solar minimum" will only be regional and won't have any effect on "global warming."

I can't make this stuff up.
Today, this item: apparently AGW is "regional." And it's driven by "natural variability." That's how scientists explain expanding Antarctic ice which dwarfs the Arctic when it comes to global ice volume. CosmosMagazine is reporting:
It’s a paradox that has scientists stumped – why, in a warming world with warming oceans, is Antarctica’s sea ice spreading and thickening each year?

Climate scientists from the US and Australia found expanding sea ice in recent years was mostly caused by natural variations in sea surface temperatures, which swamped the relatively small amount of warming due to greenhouse gases.

Sea ice – unlike the slow moving ice shelves or glacial ice – is seasonal. It forms when the ocean’s surface temperature drops to around -2 oC and chilly winds off Antarctica whip over the water, expanding and retreating each year.

Climate modelling has shown that rising sea temperatures, thanks to global warming, should stem this growth. Instead, Antarctic sea ice extends as far and wide as ever.

They found rising sea temperatures due to global warming were swamped by the interdecadal pacific oscillation, or IPO – naturally fluctuating atmospheric pressure that causes warms or cools sea surfaces over the entire Pacific Basin.

Each IPO cycle can last from 20 to 30 years. And since 1999, the IPO has been in a “negative phase”. Sea surface temperatures have plunged below average – and in Antarctica, this caused sea ice to spread far and wide.
The rate of sea ice expansion increased five-fold in 2000.
But, of course there's more.

Ever since I started blogging about AGW, I mentioned that "it all depends where you place the thermometers." The authors of this most recent study agree. I can't make this stuff up:
"This is a really complex interaction of land, atmosphere and ocean. It’s not well observed because it’s expensive – you can only look at the top of the ocean from a satellite and there are no trade routes down there," he says.
In other words, historical sea temperatures have pretty much been found only where people have placed thermometers and that was pretty much where trade ships sailed -- the northern hemisphere.

With regard to "where one places thermometers," this was posted back on November 27, 2014:
And the warmists concede: the "average temperature" of the world depends on where you place your thermometers, and if there is not a thermometer where you need one, just make up a number. (I can't make this stuff up.)
Anyway enough of this. Time to move on.

By the way, a new tag: GlobalWarming_2016_2017: the AWG year starts on the first of July every year and runs through June 30th of the following year.

Who Knows What Is True Any More?

But if, in fact, sea ice expansion increased five-fold in 2000, perhaps the graph at this link tells the story, a graph for global temperatures the past 15,000 years: http://www.iceagenow.com/Lieberman-Kerry_bill_predicated_on_a_lie.htm
