Antarctic Sea Ice Growing Despite Global Warming Warnings

The sea ice coverage around Antarctica over the weekend marked a record high, with the ice surrounding the continent measuring at 2.07 million square kilometers, according to an environmentalist and author who says the ice there has actually been increasing since 1979 despite continued warnings of global warming.

The new record was posted for the first time by the University of Illinois at Urbana-Champaign’s online record, The Cryosphere Today, early Sunday morning.

It's not apparent if the record actually occurred on Friday or Saturday, says Harold Ambler on his blog, Talking About the Weather.
Ambler is a journalist and author of the book "Don't Sell Your Coat: Surprising Truths About Climate Change."

"The previous record anomaly for Southern Hemisphere sea ice area was 1.840 million square kilometers and occurred on December 20, 2007," said Ambler. Meanwhile, he pointed out, global sea ice area on Sunday was standing at 0.991 million square kilometers above average, a figure he arrived at by adding anomalies for the North and South hemispheres.

While early models predicted the sea ice would decrease because of global warming, other models are showing that the opposite is happening around Antarctica, where sea ice growth is increasing.

"A freshening of the waters surrounding the southernmost continent as well as the strengthening of the winds circling it were both theorized as explanations for the steady growth of Antarctica’s sea ice during the period of satellite measurement," said Ambler.

However, he pointed out that climatologists have discounted the importance and growth of the Antarctic sea ice.

According to Walt Meier, formerly of the National Snow and Ice Data Center and currently of NASA’s Goddard Institute for Space Studies, most of the Antarctic sea ice does not survive between years, and it's less significant to the Earth's climate than is the ice around the Arctic.

Meanwhile, Ambler said that the growth of the Antarctic sea ice is providing "a public relations problem, at a minimum, for those warning of global warming’s menace."

During the past 18 months, global sea ice "has seen its most robust 18-month period of the last 13 years, maintaining, on average, a positive anomaly for an 18-month period for the first time since 2001," he wrote.

In addition, Ambler said, the South Pole's temperature has been dropping over the past 40 years.

A funny thing happened during Australian climate-change professor Chris Turney's venture to retrace a 1912 research expedition in Antarctica and gauge how climate change has affected the continent: Two weeks into a five-week excursion, Turney's good ship MV Akademik Shokalskiy got trapped in ice. It turns out, global warming notwithstanding, that there's so much ice down under that two ice-breaking vessels sent to rescue the research team cannot reach the Australasian Antarctic Expedition.

Years ago, global warming believers renamed the phenomenon "climate change" - probably because of pesky details like unusually cold weather undercutting the warming argument. Now, just as advocates argue that Earth is approaching a tipping point, there's so much ice floating in Antarctica during the Southern Hemisphere's summer that the Australasian Antarctic Expedition posted in a statement: "We're stuck in our own experiment."

Does this incident mean that climate change is an illusion or a hoax? Of course not. Even during its summer, Antarctica is subject to extreme weather. "Bad weather is the norm in Antarctica," climatologist Roy Spencer observed.

But it does show that like the rest of us chickens, scientists have feet of clay. Turney had told journalists that his expedition wanted to collect data that could be used to improve climate models. Too bad the folks who are supposed to predict climate decades into the future are guided by scientists who could not manage to avoid ice floes during a five-week trip.

"We were just in the wrong place at the wrong time," Turney told Fox News. He believes the ship was stuck in old ice from a 75-mile-long iceberg that broke apart three years ago.

Fair enough. But there's still the issue of ice volume. Climate changers usually warn about Arctic ice, which has been receding over the last few decades, but rarely address the overall growth of ice in Antarctica.

"I'm sure some researchers can find a possible explanation where humans are causing both Arctic ice melting and Antarctic ice growth, but I'm skeptical of scientists who blame every change in nature on human activities. Nature routinely causes its own changes, without any help from us," quoth Spencer, himself a climate change contrarian.

"Sea ice is disappearing due to climate change, but here ice is building up," the Australasian Antarctic Expedition acknowledges. It's a conundrum. If warming is melting ice in the North, why isn't it melting ice in the South?

Believers seize on all manner of weather - less Arctic ice, more Antarctic ice - as proof of climate change, but as Spencer notes, there is no climate change without man-caused global warming.

Turney told the Australian Broadcasting Corp. that his goal is to excite the public about science. As for climate change, "in the scientific community, it's remarkably solid." And "self-evident."

He pushes a framework of science being data-driven and free from politics. And yet it's hard to escape the suspicion that whatever the icebound researchers experience, they will frame it as proof that climate change is unassailable.
