Part of Antarctica has been losing ice to the ocean for far longer than had been expected, satellite pictures reveal.

A study of images along 2000km of West Antarctica's coastline has shown the loss of about 1000km2 of ice - an area equivalent to the city of Berlin - over the past 40 years.

Researchers were surprised to find that the region has been losing ice for such a length of time. Their findings will help improve estimates of rise caused by .

A research team from the University of Edinburgh analysed hundreds of satellite photographs of the ice margin captured by NASA, the United States Geological Survey (USGS) and the European Space Agency (ESA).

They found that ice has been retreating consistently along almost the entire coastline of Antarctica's Bellingshausen Sea since satellite records began.

The team also monitored and thinning rates using data taken from satellites and the air. This showed that some of the largest changes, where ice has rapidly thinned and retreated several miles since 1975, correspond to where the ice front is deepest.

Scientists suggest the loss of ice is probably caused by warmer ocean waters reaching Antarctica's coast, rather than rising air temperatures. They say further satellite monitoring is needed to enable scientists to track progress of the ice sheet.

Their study, published in Geophysical Research Letters, was carried out in collaboration with Temple University in the US. It was supported by the Carnegie Trust for the Universities of Scotland, the Natural Environment Research Council and the ESA.

Frazer Christie, a PhD student in the University of Edinburgh's School of GeoSciences, who co-led the study, said: "We knew that ice had been retreating from this region recently but now, thanks to a wealth of freely available satellite data, we know this has been occurring pervasively along the coastline for almost half a century."

Dr Robert Bingham, also of the School of GeoSciences, said: "This study provides important context for our understanding of what is causing to retreat around the continent. We now know change to West Antarctica has been longstanding, and the challenge ahead is to determine what has been causing these losses for so long."

When the sea level rises a little more, it can invade the San Joaquin Valley, where much of your food is grown.

But you can just deny the happening and pretend you are still eating.

Jun 01, 2016
Gkam - considering how many people are NOT from the U.S. on this site, your comment makes no sense. Don't be such a parochial twat.

Besides, Cali can use fewer *ahem* fruits and nuts.

Jun 03, 2016
On the other hand, the the overuse of ground water is causing the ground level to sink MUCH faster than the the sea level is rising.

On both hands, I suggest you learn to grow your own food.

Jun 03, 2016
Its working, dumbass, I live on 400 acres in the Willamette Valley. We grow Hazelnuts, Peaches, Marionberries, Apples, Pears, and more. Ha Ha Ha Ha. I don't have to worry that the neighbors might cheat on their water rationing and the land sink into the sea.

My wife can sell you some when you get hungry enough.

Jun 04, 2016
Tell her to call me. I want her to know what kind of person you are online. I am sure she will be impressed.

And what was your comment about fruits and nuts?

Jun 04, 2016
Yeah sure, she be a callin' you right up. She knows I have a low tolerance for whiners, neither does she, but she hides it better.

You are a fruit and have no nuts. Hey man, you asked.

@Estevan57
you lucky bad*ss you!.... that is one beautiful part of the country

just for the record, i learned to track just north of your area in the Cascades and Olympics (mostly in WA but occasionally down on Hood)

... and there aint no cheese like TIllamook cheese LOL
(still my favourite ... )

do you remember the crazy "artesian" and other commercials for Raineer beer back in the 80's?
LOL
send me a PM on my profile on SciForums - Truck Captain Stumpy
I need me some St. Helens ash - LOL

pot - kettle - black

any questions?

Jun 04, 2016
Yes, . . are you still posting my Social Security Number online?

Are you aware of your potential liability?

Jun 04, 2016
so... it's ok to be OT and spam the thread so long as it's you doing the spamming and OT posting... is that it?

I will answer this... but this one time only in this thread...
if you continue to rant/spam then that i will abide by our established agreement
Are you aware of your potential liability?
more so than you are because, unlike you, i know a little about the law
...and i also contacted legal representation given your threat

are you aware of your own "potential liability?"
(i'm guessing not considering ...)

where is my subpoena or summons?

you made the threat... you have my home address... so where is it?

still waiting

Jun 04, 2016
No,I do not have your "home address".

You are too scared to put it down here, afraid I will show up, . . or tell your Mommy.

And please keep your need to "get even" with me on Twitter or some other adolescent forum suited for it.

Thank you.

Jun 04, 2016
*sigh* - ok... one last post, since you are not capable of comprehending basic english
And please keep your need to "get even" with me
hey stupid ... you are the one who posted to me trying to denigrate my post and "get even"... not the other way around
No,I do not have your "home address"
it was embedded in the link, ya moron

ignorance and stupidity is no excuse, nor would a judge excuse you under the circumstances, especially considering it's common knowledge (unless, of course, you are inept - but then again, courses learning internet/computer basics are typically free or cheap for geriatrics)

feigning stupidity as well as geriatric memory loss isn't a viable option either considering your "degree"... though dementia may well be used - except that the first thing typically taught is to make notes about important stuff - so fail there too

last post to you about this topic unless you want to take it to a moderated site or e-mail
ok?

thanks, ya troll

Jun 04, 2016
Wow. Nastiness seems to be your sole basis for being here.

Is my Social Security Number STILL posted online by you?

Jun 04, 2016
Oh,my,. . . now Grumpy is sending me nasty emails with all kinds of accusations and other verbal effluvia.

I guess some folk have fixations, . . .

In some areas, not everywhere.

Sea level is rising everywhere.

george kamburoff doesn't understand that giving out his SS# to strangers (hostile strangers mind you) is the same as leaving his wallet on a table at McDonalds and then posting it's location online and telling people not to touch it.

Georges sickness tells him that he can command people to fix the incredibly stupid mistakes he makes. And when they don't get fixed he then has somebody to blame it on.

George, posting the personal info you give out is a very good way of demonstrating how stupid you are. And since you gave it out freely there is no liability involved.

Jun 04, 2016
@Magnus - Exactly my point. 28 feet is an astounding amount of ground level loss for areas of the San Joaquin Valley. And it is directly attributable to excessive pumping for agriculture.

And the sea will rise to meet it, unfortunately.

To clarify - Please don't think I am denying sea level rising. That's not my bag, baby.

interesting article... got anything else on it?
I would love to see more studies on that area and that situation if ya have any - gonna look some up for myself too
thanks for sharing it

@Whyde
at this point it's about attention
- as you can see, she doesn't want resolution (as noted by the failure to utilise moderated sites etc)

ignoring her would be a far better use of time and energy

Jun 05, 2016
I delete the email from Rumpy. Why would you want to see it? It is the same silly nonsense as the posts here.

These folk got mad because I had some experiences with the issues here, and they did not believe it. When I proved all my assertions, they REALLY got mad. I guess they are used to being the Big Bad Dogs here, but they are just anonymous trolls.

Send me an email address, and you can get the proofs too. Meanwhile, Grumpy posted much of it online, including my SSN. Go back and find the address of the postings,and you can read my performance reports from the Air Force.

But it all started when I posted what they thought was phony stuff like they post. It was inconceivable to them that one person would have that broad range of experience, but I did not engineer the path of my life. What I did do is live it honestly.

Now who are the snipers here? Who are they really, and why are they hiding?

Jun 05, 2016
As far as sea level rise, we are in for it. We will lose much of the Gulf Coast, possibly the entire Central Valley of California, where you get your food, and many coastal cities. And inland folk have to worry about the sea level backing up the rivers, like in California.

Many Deniers will once again realize how wrong they are. But they will excuse themselves from sin, unable to accept that.

As is typical for this idiot, he is confusing post-glacial rebound (a movement of the continental crust resulting from the loss of glacial ice-http://www.cs.mcg...und.htm) with rising sea levels (an increase in the level of ocean water as a result of increasing temperature and ice sheet loss). His blog hero makes the same stupid mistake.

It always amazes me, for some reason, how stupifyingly vacuous and simple-minded this poor child is.

Saying it's true when it's not only works with your poor frightened family georgie.

You posted lies, you were challenged, you sent proof, and the proof turned out to be more lies.

I think it's time we compiled your bullshit on a separate page which can be linked every time you lie. It may take a little work but it's the only way to give people a comprehensive idea of just how sick you are.

And of course it will include all the personal info you have so graciously surrendered to the public domain.

Jun 05, 2016
Maybe captain Stumpy is fed up enough with you to take on this little task because he has stuff you sent him and also offsite communication with Ira.

I've got an early list which I'll be happy to add, as well as time to comb through past threads.

i am in the process of building it now (with a blog which is separate)... it will take a little time to get it all set up

I do have the photobucket album for specifically for g that i will link to a page, and working on various blog entries to show how people can learn from the general stupidity

but also working on a specific anti-stupid page to out the more blatantly stupid posters on PO
I've got an early list which I'll be happy to add, as well as time to comb through past threads
if you contact me on SciForums (truck captain stumpy) i can give you an e-mail addy and you can forward what you have

feel free to add as much as you like... just give me some time to complete the work as i am learning python for certain apps, etc (and i hate programming, so it's slow going)

thanks

Jun 05, 2016
important note:
if you contact me on SciForums (truck captain stumpy) i can give you an e-mail addy and you can forward what you have
like always i will state that the best choice of action would be to utilise an e-mail service like g-mail or another disposable e-mail service to insure that personal information isn't freely disseminated (because it really is stupid to knowingly accept a condition to allow the general public access to your personal private information like a SSN... this is where reading and comprehension really bit g on the buttocks and why he has no legal recourse against stolen identity - almost sad, really)

hell, even the gov't says not to do it, along with any internet class and law enforcement!

I blogged about this recently...

LOL

She gave me some for free, though she got the nuts from me.

You don't mention that the hazelnuts and Himalayan Blackberries are wild. That's gathering, not farming. "Pernicious yet delicious" I always say about the latter. And a bugger in the butt to mountain bike tyres!!!

As expected Magganus blows out of his anus.
Have a gander of how much higher the sea level was in the 1950s. So, the earth is not just rebounding, but must actually be (re)bouncing.
It NEVER amazes me, for OBVIOUS reason, how stupifyingly vacuous and simple-minded this poor anus is.

@AGreatWhopper The Hazelnuts are planted as an orchard, in rows. They are irrigated from wells, and fertilized according to ph samples and moisture content. That would probably qualify as farming. We call them Filberts here. 2.1 metrics tons of nuts is a lot of gathering.

Marion berries are planted on a wire structure similar to that used for grapes. Also in rows. Irrigated, etc. They aren't the same as most blackberries, they are bred for size, flavor, ease of harvest, and small thorns.

Himalayan Blackberries are an invasive species here.

As for your nuts, any story about them would probably be a great whopper, so to speak.
