Antarctic Adélie penguin chicks wiped out because of too much sea ice

by Tommy Monk Wed Oct 18, 2017 11:22 pm

All but two Adelie penguin chicks have starved to death in their east Antarctic colony, in a breeding season described as "catastrophic" by experts.

It was caused by unusually high amounts of ice late in the season, meaning adults had to travel further for food.

It is the second bad season in five years after no chicks survived in 2015.

Must be all this 'global warming' that caused the high level of sea water to freeze down there...!!!

This warped Tommy Monk perspective on this story is pure bullshit, as presented here...

I saw this disaster reported on television here last week, and the true story simply doesn't gel with Tommy's idiotic spin and conclusion on that tragedy..

Nothing new there, in Tommy's anti-science stupidity.

"The region is impacted by environmental changes that are linked to the breakup of the Mertz glacier since 2010," Yan Ropert-Coudert, lead researcher on the Adélie penguin program at France's National Center for Scientific Research (CNRS), said in a statement.

"An MPA will not remedy these changes but it could prevent further impacts that direct anthropogenic pressures, such as tourism and proposed fisheries, could bring."

Last year, research by oceanographers at the University of Delaware found that 60% of Antarctica's Adélie penguin habitat may become unsuitable for the birds by the end of the 21st century, because of warming seas and rain.

New research shows penguins will suffer in a warming world

Posted on 4 August 2016 by dana1981

We know the world is warming, and we know humans are the main reason. But so what? The thing we’d really like to know is, what will the impacts be on our planet, its biodiversity, our society, our economies? It is only through understanding the impacts of climate changethat action for reducing greenhouse gases can be motivated.

This is one of the reasons I was so interested in a very recent study from the University of Delaware, which addressed how penguins will fare in a warming world. The article was published in Scientific Reports and is available open access so anyone with an internet connection can read it here.

Lead author Megan Cimino and her colleagues looked at Adelie penguin populations and asked whether their years of increasing or decreasing population corresponded to warm, cold, or normal temperatures. In the Antarctic, which is where these penguins live, the situation is a bit complex because the land area is large and weather/climate changes are not consistent across the region.

For instance, large parts of the Western Antarctic Peninsula (WAP) are warming quite rapidly, amongst the most rapid in the world. On the other hand, in the East, some areas are warming just a little while others are cooling slightly. Since Adelie penguins live on the periphery of the ice sheet, they are exposed to a wide range of Antarctic climate regions.

The authors found that penguin colony declines occur preferentially in years where the sea waters are warmer than average. This is in contrast to colonies whose populations are stable or increasing – those occur in normal or cooler waters. This finding was particularly striking when Adelie penguin populations in the WAP (which is warming) were compared with populations elsewhere in the continent.

This knowledge of past penguin colony health was obtained by actual measurements, primarily satellite data which provided sea surface temperatures and ice extent. But the important extension of this work is into the future. The scientists took their current knowledge of penguin health and climate and asked what will happen to these penguins in the future.

Since we do not have measurements in the future, the scientists used climate models. These models are computer calculations of the actual climate that will exist in the future, and the calculations are based on our best understanding of how the climate system works. Fortunately, climate models have an excellent history in predicting how the future will evolve. While climate models are never perfectly accurate, they give enough information so that researchers like Megan and Matthew can make educated predictions.

The predictions that emerged from the study are that approximately 20% of the penguin populations may be in decline by 2060. As the planet and oceans continue to warm, the pressure on penguins will increase. However, the researchers also report that the penguins will not completely die out. There will remain refugee communities of penguins that exist beyond 2100. We can be grateful for this silver lining.

Natural forces overpowering Antarctic Peninsula warming

Posted on 4 August 2016 by Guest Author
This is a re-post from Carbon Brief by Roz Pidcock

In the latter half of the 20th century, the tip of the Antarctic Peninsula was among the fastest warming places on Earth. But since the late 1990s, this fast-paced warming has been tempered by extreme natural forces, according to new research. So much so, that some parts have switched to cooling.

In many ways, the results are unsurprising. Scientists know that natural variability superimposes temporary ups and downs on top of greenhouse gas-induced warming everywhere on Earth.

Prof Robert Mulvaney, part of the team of British Antarctic Survey scientists who carried out the research, tells Carbon Brief:

“The results are as we would expect.”
The authors of the study, published today in Nature, also stress their findings are restricted to a small part of the Antarctic Peninsula, and do not imply cooling across the ice sheet as a whole.

Tommy seems to think he has stumbled onto something new here.

Why don't you tell us, didge...!?

by Guest Fri Oct 20, 2017 8:34 pm

No problem Tommy

Christopher Shuman, a University of Maryland, Baltimore County glaciologist working at Goddard, said: "Field data suggests that there’s been a modest cooling in the area over the 2009–2015 time period, and images collected during that time by the Moderate Resolution Imaging Spectroradiometer on the Terra and Aqua satellites show more persistent fast ice (sea ice that is attached to the shore) in the Larsen A and Larsen B embayments”

However, Mr Shuman warned that in some areas of the Antarctic, glaciers continued to melt at significant levels, despite the slight temperature drop.

At the south pole, the mission observed a big drop in the height of two glaciers situated in the Antarctic Peninsula.

Mr Shuman added: "These IceBridge measurements show that once the ice shelves collapse, even some cooling and a good deal of persistent sea ice is not able to hold back these larger glaciers and they continue to lose mass overall.”

During one flight in the Peninsula that mapped the drainage area of several glaciers, a drop of more than 490 feet (150 meters) in the height of two glaciers since IceBridge last plotted them, in 2009, was measured.

Both glaciers, called Green and Hektoria, were tributaries to the Larsen B ice shelf, which disintegrated in 2002.

After the ice shelf collapsed, it stopped buttressing the glaciers that fed it, and glacier elevations have fallen dramatically since then.

A study published in 2012 showed average elevation losses of up to 82 feet (25 meters) per year for the lower Green and Hektoria glaciers from 2006 to 2011.

A NASA spokesman said:"So IceBridge’s discovery that both are still losing ice fast many years after the loss of the adjacent ice shelf is “not all that surprising given what we have observed with other sensors,” said Mr Shuman.

So, confusingly, the new details of further glacial melt have fuelled those who believe we are causing global warming and polar ice melt.

At the Arctic north pole, the project collected much needed measurements of the status of land and sea ice at the end of the Arctic summer melt season.

The results of these have yet to be published, but the whole issue is set to be debated in full at a clime change conference in Paris later this month.

Abstract

Ice shelves play a vital role in regulating loss of grounded ice and in supplying freshwater to coastal seas. However, melt variability within ice shelves is poorly constrained and may be instrumental in driving ice shelf imbalance and collapse. High-resolution altimetry
measurements from 2010 to 2016 show that Dotson Ice Shelf (DIS), West Antarctica, thins in response to basal melting focused along a single 5 km-wide and 60 km-long channel extending from the ice shelf's grounding zone to its calving front. If focused thinning continues at present rates, the channel will melt through, and the ice shelf collapse, within 40–50 years, almost two centuries before collapse is projected from the average thinning rate. Our findings provide evidence of basal melt-driven sub-ice shelf channel formation and its potential for accelerating the weakening of ice shelves.

Plain Language Summary

Ice shelves act as safety bands around the Antarctic ice sheet. Many ice shelves are currently thinning, leading to acceleration of the grounded ice behind. Here we show that ice shelves' thinning is stronger along a channel structure formed by the ocean circulation under the ice shelf. The thinning is 3 times higher than the ice shelf's average, hence leading to a more rapid weakening of the ice shelf. This study provides evidence of basal melt-driven sub-ice shelf channel formation and its potential for accelerating the weakening of ice shelves.

Antarctic Sea Ice Sets Record Low, Providing Another Mystery for Scientists

A new record warm temperature for Antarctica was confirmed by the World Meteorological Organization as sea ice surrounding the continent has shrunk to a record low.

The temperature reached its record high of 63.5 degrees Fahrenheit on March 24, 2015, according to an announcement by the WMO, which often takes years to verify new records.
The news came as sea ice around Antarctica is experiencing its lowest extent ever. As of March 1, only 820,000 square miles of the ocean around Antarctica was covered in ice, according to data from the National Snow and Ice Data Center in Boulder, Colo. The loss of ice represents an all-time minimum for Antarctic sea ice cover since satellite observations began in 1979.

The current decline, however, may not be part of a larger climate change trend. The low point comes less than three years after Antarctic sea ice set a record high in October 2014. "If you look at the long-term trend, Antarctic sea ice is still increasing slightly, said Son Nghiem, a researcher with NASA's Jet Propulsion Laboratory.

That increase has provided fodder for climate denial arguments and was a mystery to scientists because it differed so greatly from the rapid melting occurring in the Arctic. But recent research has provided clues to the reasons. The continent's unique topography shields it from warming occurring elsewhere, Nghiem said.
A study Nghiem and colleagues published last year found that topography creates icy winds blowing off Antarctica and a powerful ocean current that circles the continent. The study, published in the journal Remote Sensing of Environment, concluded that these two factors play a larger role in the formation and persistence of Antarctic sea ice than changes in temperature.

"I think Antarctic sea ice will be stable for at least some time into the future," Nghiem said.

That puts it in direct contrast with the Arctic, which is losing its ice at a rapid clip as it experiences a record-warm stretch and record low levels of sea ice at the North Pole. Last month temperatures in the far north were 20 degrees above normal according to data from the Danish Meteorological Institute. The ice cap over the North Pole receded to a record low in January for the second year in a row according to the National Snow and Ice Data Center.

Writes his story based on headlines, but doesn't read the actual story..

Doesn't understand science; but still claims to know more than the scientists.

Doesn't understand climate, but claims to know more than the climatologists. And more than those people actually experiencing extreme and whacky weather firsthand..

Tommy most likely couldn't even find Antarctica on a map -- and yet still claims to know more about it than those actually working there !!!

Truly one deluded twonk, is poor ol' Tommykins..

New research shows penguins will suffer in a warming world

Posted on 4 August 2016 by dana1981

We know the world is warming, and we know humans are the main reason. But so what? The thing we’d really like to know is, what will the impacts be on our planet, its biodiversity, our society, our economies? It is only through understanding the impacts of climate changethat action for reducing greenhouse gases can be motivated.

This is one of the reasons I was so interested in a very recent study from the University of Delaware, which addressed how penguins will fare in a warming world. The article was published in Scientific Reports and is available open access so anyone with an internet connection can read it here.
Lead author Megan Cimino and her colleagues looked at Adelie penguin populations and asked whether their years of increasing or decreasing population corresponded to warm, cold, or normal temperatures. In the Antarctic, which is where these penguins live, the situation is a bit complex because the land area is large and weather/climate changes are not consistent across the region.
For instance, large parts of the Western Antarctic Peninsula (WAP) are warming quite rapidly, amongst the most rapid in the world. On the other hand, in the East, some areas are warming just a little while others are cooling slightly. Since Adelie penguins live on the periphery of the ice sheet, they are exposed to a wide range of Antarctic climate regions.

The authors found that penguin colony declines occur preferentially in years where the sea waters are warmer than average. This is in contrast to colonies whose populations are stable or increasing – those occur in normal or cooler waters. This finding was particularly striking when Adelie penguin populations in the WAP (which is warming) were compared with populations elsewhere in the continent.

This knowledge of past penguin colony health was obtained by actual measurements, primarily satellite data which provided sea surface temperatures and ice extent.

Since we do not have measurements in the future, the scientists used climate models. These models are computer calculations of the actual climate that will exist in the future, and the calculations are based on our best understanding of how the climate system works. Fortunately, climate models have an excellent history in predicting how the future will evolve. While climate models are never perfectly accurate, they give enough information so that researchers like Megan and Matthew can make educated predictions.

The predictions that emerged from the study are that approximately 20% of the penguin populations may be in decline by 2060. As the planet and oceans continue to warm, the pressure on penguins will increase. However, the researchers also report that the penguins will not completely die out. There will remain refugee communities of penguins that exist beyond 2100. We can be grateful for this silver lining.

Click here to read the rest

This article clearly claims that Adelie penguins are killed off by warmer than usual temps in their environment... but stronger and more stable when normal or cooler than usual temperatures are in their environment...!!!

And all based on 'scientific studies'...!!!

But the OP says that a load have died off because it is colder in area than usual, and because there is more sea ice...!!!

And first prize goes to Tommy for being the worlds biggest idiot.

So is it possible there is more than one type of problem with weather, that effects these penguins?

Showing how delecately balanced the tempreture needs to be or the penguins will suffer?

You do know this happens to many species Tommy?

Or did this not compute with that tiny tiny brain of yours

Did you not also notice that the article states it is looking at the problem? Not that it is definately the problem?

And this is why as seen you are by everyone seen as an utter joke on science, Tiny Tommy.

lol!

That I fully understood...!

I then posted a couple of quotes and then a link from the Express...

That backed up the OP claim of increased sea ice in the area in question...!

You then posted up stuff that confirmed all of this...!!!

So... unless you can tell us exactly what it is that you disagree with, in what I have posted here...?

Then it can only be the case that you agree with everything I've posted here...!?

You need to provide facts Didge... not your vague assumptions on what you think I have read/understood etc...!

Now Tommy do you believe in human intervention of climate change? Which is clausing climate change?

Yes or no?

Hence why

You posted a thread about the plight of penguins.
Never understanding any of it.
You posted a couple of quotes and then a link from the Express.
Clearly never reading that either.. Laughing
I posted information to help you understand this.
Exposed then, that you never read your link and since then you have failed to admit to your cockups here.
This is evident by the post above where you pull out one aspect and something known, that in some areas its getting colder. Ignoring everything else.

It appears you are not very bright Tommy Laughing

I mean for starters, how many chicks survived this seasons breeding of Adelie Penguins?

Now you made a comment in your first thread based on climate change did you not?

You then proceeded to make a complete muppet of yourself and are doing the same here.

Like I said, there is many reasons weather based that effect these penguins.

You went off one event. Even worse never understanding the cause for this event. Which has happened before.

Now the one question I highlighted, lets see how smart you really are

Cool

You still haven't answered my question...

I've asked you to point out exactly what I've posted that you disagree with...!?

Well...???

I have done that Tommy countless times and yet you still look a complete dummy

Now I know why you could not answer my question.

As if you said 2 chicks, I would laughed my pants off at you.

As this was one of 251 colonies of these penguins. That the disaster happened.

You in your stupidity posted this and by your comment on climate change. As if to argue against this.

Negating any understanding of the penuine colonies or how climate change effects them.

As Manisha Ganguly reports for CNN, the devastating event was caused by unusually high amounts of sea ice surrounding the Adélie penguins’ breeding ground. The ice forced adult penguins to travel farther for food, and by the time they returned, most of the chicks had died of starvation.

"This devastating event contrasts with the image that many people might have of penguins." Rod Downie, head of Polar Programs at World Wildlife Fund, says in a statement. "It’s more like ‘Tarantino does Happy Feet, with dead penguin chicks strewn across a beach in Adélie Land."

It is the second time in recent years that the colony has suffered a “catastrophic breeding failure,” as the WWF put it in its statement. In 2015, not a single chick survived after rains and a subsequent cold spell caused them to freeze to death.

The Adélie penguin is the smallest and most ubiquitous Antarctic penguin species. Between October and February, the penguins gather on coastlines across Antarctica to breed. The chick die-off occurred at the start of 2017, affecting a colony of about 36,000 penguins, which are monitored by researchers with France's National Center for Scientific Research (CNRS).

Quantities of sea ice in polar regions fluctuate every year, but as the Associated Press reports, climate change has made the variations more extreme. Adélie penguins are deeply affected by changes to their habitat; a recent study projected that between 25 and 58 percent of the birds’ colonies may be in decline by 2060.

Environmental officials are meeting this week in Hobart, Australia to discuss the possible creation of a Marine Protected Area off the coast of eastern Antarctica. The zone would prohibit krill fishing in the area, thereby preserving Adélie penguins’ primary food source.

A protected region won’t mitigate the effects of climate change, of course. But as Yan Ropert-Coudert, a marine ecologist at CNRS, tells the AP, it can help decrease fishing and tourism, which also pose a threat to the penguins.

So as seen, they are effec ted by many weather problems. Hence my other article was also spot on.. Cool

Also

The Adélie is the littlest, and also the most widespread, species of penguin in the Antarctic.

They might look a bit clumsy on land, but penguins are brilliant swimmers. They can dive down to 180m – though they tend to catch their food (mainly krill and fish) much closer to the surface.

Penguins may seem cute to us, but they're excellent predators and very efficient foragers. Adélies have a feisty attitude too. They’ve been known to take on potential predators – seals or large seabirds – or even attack visiting researchers with their flippers.

Adélie penguins are increasing in Antarctica. However, in areas where climate change is established, Adélie populations have fallen by more than 65% in the past 25 years. The biggest threat to them right now is climate change (other penguins, like gentoos, are better adapted to warmer climates).

So there is only one thing left to ponder.

Do you back your first view, that Global warming is to blame for this disaster?

Yes or no?

You're the one who constantly looks the twat on here, Tommy...

You contradict yourself with the quotes you attempt to use to back your own warped agendas; on this topic, on your climate change denials; on your nazi revisionism..

You keep on attacking Didge, me, Ben, veya, Andy across various threads-- and you keep on claiming that you know more than the scientists and academics, themselves.

And you have the audacity to call others twats, liars, fools -- with zero evidence ?

All the while, the only idiots supporting your idiotic stance are a handful of your equally clueless fellow Floptard fuckwits..

by Tommy Monk Sat Oct 21, 2017 2:30 pm

So Didge still can't point out anything I've said here that is wrong...!!!???

lol!

And fleakeeper sill can't understand the OP was a quote from the BBC article of the link showing in OP...!

What a twat...!!!

lol!

by Guest Sat Oct 21, 2017 2:32 pm

Oh dear Tommy has gone into meltdown mode, after being made to look very silly

Priceless

I shall now leave him to sulk

Cool

by Tommy Monk Sat Oct 21, 2017 2:42 pm

Didge posted this a little while ago...

"...As Manisha Ganguly reports for CNN, the devastating event was caused by unusually high amounts of sea ice surrounding the Adélie penguins’ breeding ground. The ice forced adult penguins to travel farther for food, and by the time they returned, most of the chicks had died of starvation..."

Again confirming what the BBC article in OP said...!!!

And the deluded twat thinks he is 'winning'...!!!

Most amusing!!!

lol!

by Guest Sat Oct 21, 2017 2:45 pm

Indeed it does confirm that climate change is causing this in parts of Antartica. That sees in some parts cooling and others warming, effecting the weather.

It also points out how many other colonies are effected by climate change with warming in the area.

Two causes that create mass problems for the penguins.

I love it when Tommy desperately tries to dig himself out of a hole. Never for one minuite thinking about the other 250 colonies.

Priceless

But Didge... you posted a 'scientific' article earlier that specifically said that the adelie penguins thrived in colder than usual times... but the op is showing that this was a colder than usual time resulting in more sea ice, and the penguins suffered tens of thousands of chicks died...!
