Antarctica – 91 volcanoes coincidentally found under glaciers warming “due to climate change”

It’s possibly the densest concentration of volcanoes in the world, some as high as 4km and we didn’t even know these existed til recently.  Despite that overwhelming ignorance, we’re 97.00% certain that all the warming in Antarctica is due to your car and airconditioner. Robin McKie, The Guardian writer, talks about the recent discovery of so many volcanoes under the ice. Not surprisingly, we have no data on how active these volcanoes are. However because we *know* climate change is definitely wrecking Antarctica, it follows that your car, air conditioner and pet dog could melt more ice, take the pressure off the tectonic plate and set one off. Then things will really get out of hand.

Anyhow, it’s just a coincidence that all the warming in Antarctica is where the volcanoes are.

From The Guardian: Scientists discover 91 volcanoes below Antarctic ice sheet

Scientists have uncovered the largest volcanic region on Earth – two kilometres below the surface of the vast ice sheet that covers west Antarctica.

The project, by Edinburgh University researchers, has revealed almost 100 volcanoes – with the highest as tall as the [...]

There have been far bigger Antarctic icebergs than the latest A68 Larson C berg

CNN is  “freaking out” about the latest large iceberg. But John Sutter doesn’t mention that there was an iceberg twice its size in the year 2000 which was 11,000km2, and that as long ago as 1967, two other icebergs of a similar size were recorded. Thanks to John McLean for the links.

UPDATE:  Tony Heller has found a newspaper story about an even bigger one from 1956. This monster iceberg was allegedly 334km x 96km or 32,000 km2.  (h.t John of Cloverdale).

UPDATE #2: Monster bergs are everywhere. Lazzara lists two other massive icebergs as well as B15 that occurred in just 18 months: A38 in Oct 1998 was  7,600km2 and A43 in May 2000 was almost as big as B15, being 9,250km2. h/t WS All three of these were larger than the current “freak”.

When it comes to long term trends in iceberg sizes, the only scientific answer is “who knows”. Satellite records are so short, if a bigger iceberg broke off in say, 1811, how the heck would we find out? Not much is left of an iceberg 100 years later. What kind of proxy could show it ever existed — ancient stone carvings of satellite pics from [...]

There goes that scare: Antarctic Peninsula cooling by almost 1 degree

Don’t panic now, but all the coal burnt in China has been cooling the Antarctic Peninsula.

For the last twenty years, The Antarctic Peninsula was the poster-peninsula for the Global Worriers as they calculate how many meters the oceans will rise when it melts, but all across it, temperatures are going down, not up.

We can knock half to one degree off:

 This cooling has amounted to a 0.5 to 0.9 °C decrease in temperatures in most of the Antarctic Peninsula region, the only exception being three stations located in the southwest sector of the peninsula that experienced a slight delay in their thermal turning point, declining only over the shorter period of the past decade.

Thanks to CO2Science: The Antarctic Peninsula: No Longer the Canary in the Coal Mine for Climate Alarmists

….

The start points matter. The cooling started after 1998, which was an El Nino, and we can see there was a similar downward slope from 1983 to 1993. As usual, with a climate graph, there are steps and stairs, and there is a trend up in the last 50 years (but probably down in the last 7,000).Whatever.

What there isn’t, most definitely, [...]

Antarctic scientists may find climate Holy Grail, ice with magic 7 digit age

ABC news tells us intrepid researchers are in a race for the sacred key. The news is a sexed up advert for climate funding done in the theme of Raiders of the Lost Ice:

“It’s the “holy grail of climate science”, a piece of ice so old that it might be able to reveal the climate of the past and help predict the future of Earth’s atmosphere.

And Australia’s Antarctic scientists are now part of an international race to find the ancient time capsule.

So, what is it?

Somewhere deep below the surface of Antarctica, ice has laid untouched for a million years or more — it’s believed to be the world’s oldest ice“

I don’t know why scientists think the million year mark is so holy, they’ve pretty much ignored the message in the first 800,000 years. They hunted and drilled but the telex from prehistory kept saying temperature controls CO2, not the other way around.

Either CO2 followed the temp, or CO2 stayed high, but temp did its own thing. (See the spot from circa 130,000BC, for about 15,000 years? CO2 was at “record highs” unseen for 120,000 years, but that didn’t stop [...]

Antarctic sea ice strangely the same as 100 years ago when Ford Model T was around

A hundred years of cars, planes, wars, and five billion more polluting people, and there’s nothing to show for it. Old log books kept by Scott and Shackleton show that Antarctic sea ice hasn’t changed much since 1912. Right now, at least three ecowarriors are rejoicing that perhaps there is a future for penguins after all.

Scott and Shackleton logbooks prove Antarctic sea ice is not shrinking 100 years after expeditions

“The missions of Scott and Shackleton are remembered in history as heroic failures, yet the data collected by these and other explorers could profoundly change the way we view the ebb and flow of Antarctic sea ice,” said Dr Jonathan Day, who led the study, which was published in the journal The Cryosphere.

“We know that sea ice in the Antarctic has increased slightly over the past 30 years, since satellite observations began. Scientists have been grappling to understand this trend in the context of global warming, but these new findings suggest it may not be anything new.

“If ice levels were as low a century ago as estimated in this research, then a similar increase may have occurred [...]

Backflip: Antarctic peninsula, posterchild of Polar disaster, has been cooling not warming

The “fastest warming place” on Planet Earth wasn’t warming.

A new Antarctic study wipes out 20 years of panic about the West Antarctic Peninsula. All these years while people were crying about penguins, it turns out that the place was cooling rather than warming. Mankind has emitting a third of all its “CO2-pollution” ever from 1998, and there was “no discernible” effect on Antarctica. Indeed,  the study quietly finds that even the bigger longer warming that has happened in the last century was not “unprecedented” in the last 2000 years.

In the last decade as this cooling trend was happening in the real world –  in the media, the same spot was being described as “one of the fastest warming places on Earth”:

And this sort of news has been going on for years. This was “big deal” once-in-2000 year type stuff:

UK scientists say parts of Antarctica have recently been warming much faster than most of the rest of the Earth. They believe the warming is probably without parallel for nearly two thousand [...]

CO2 hits record high: Antarctic temperatures do nothing

The terrifying effect of CO2

Feel the panic.

South Pole CO2 levels cross 400 ppm first time in 4 million years!

WASHINGTON: The Earth passed another unfortunate milestone when carbon dioxide levels surpassed 400 parts per million (ppm) at the South Pole for the first time in 4 million years, according to US scientists.The South Pole has shown the same, relentless upward trend in carbon dioxide (CO2) as the rest of world, but its remote location means it is the last to register the impacts of increasing emissions from fossil fuel consumption, the primary driver of greenhouse gas pollution, researchers said.

In response, the South pole temperatures “pause”

Nature – finally “finds” cause of Antarctic pause, will last centuries, tosses “global warming” out

Nature ties itself in knots here, and reveals a lot more than they probably meant too, but mostly about themselves rather than about Antarctica. If it’s correct, the implications from this study are pretty big, not that the study will tell you that. The term “Global warming” is tossed under a bus, along with almost all the Antarctic man-made scares of the last two decades. The political nature of Nature is on full display.

This time Nature claims it has found the cause of the Antarctic pause.  Apparently this now finally resolves yet another conundrum (fantastic, what!) that was, as usual, not called a conundrum until it was solved. Another secret problem fixed. Where was the press release telling us there was a problem?

Those who said there was a conundrum were just deniers. It’s right there in the press release, paragraph two:

The study resolves a scientific conundrum, and an inconsistent pattern of warming often seized on by climate deniers.

Which rather begs the question: If there was a conundrum then the skeptics who pointed it out were not deniers, but correct. And if there was no conundrum, and deniers were denying something, then this is not [...]

1000 year rainfall study suggests droughts and floods used to be longer, worse

A study done on… golly, Antarctic Ice, allegedly shows that in the catchment area for Newcastle in NSW, Australia, the last 100 years have been pretty darn nice, compared to the past when droughts and big-wet periods used to last a lot longer.

Set aside, for a moment, that the ice cores are thousands of kilometers away and in a totally different climate, if they are right, if, then natural climate change is much worse than our short climate records are telling us. And if our current records are so inadequate and don’t represent the “old-Normal”, then we have a flying pigs of predicting the “New Normal”. Has the climate changed at all, or is the new one just like the old old one?

Hydroclimatologist and lead author, Dr Carly Tozer from the ACE CRC said the research showed exposure to drought and flood risk was higher than previously estimated.

“The study showed that modern climate records, which are available for the past one hundred years at best, do not capture the full range of rainfall variability that has occurred,” Dr Tozer said.

“The wet and dry periods experienced since 1900 have been relatively [...]

Hot magma is melting Greenland ice – can windfarms save it?

Here on the ball of magma called Earth, there’s a hot plume of rocks under Iceland that stretches right across under Greenland. Those hot rocks are melting the ice from below in a band 1,200 km long and 400 km wide.[1]

I don’t think solar panels are going to stop Greenland melting.

The main part of the plume has been progressing eastward over the last 120 million years, right under Greenland and now lies under Iceland.

Will the media take a million years to catch on?

Presumably, being world class journalists, from now on all ABC/BBC/CBC stories will not mention melting Greenland ice-sheets without also noting that geothermal heat may be causing it instead of your long hot showers.

But a similar study published in Nature Geoscience 3 years ago was the forerunner to this one with similar conclusions and the mainstream media don’t seem to have noticed yet.[2]  No mention of magma, tectonics and hot rocks here: ABC — [...]
