Two degree rise could spark Greenland ice sheet meltdown: WWF

news.yahoo.com

GENEVA (AFP) – A less than two degree Celsius rise in global temperatures might be sufficient to spark a meltdown of the Greenland Ice Sheet and Arctic sea ice, the WWF warned in a new study released Thursday.

The financial meltdown is not the only meltdown problem because Arctic ice is melting faster than predicted. I guess we are melting from all angles.

They also say

"Scientists now suggest that even warming of less than 2 degree Celsius might be enough to trigger the loss of Arctic sea ice and the meltdown of the Greenland Ice Sheet," the WWF said in a statement to accompany the findings.”

So would a cool down by 2 degrees instead cause massive amounts of water to freeze and there to be a water shortage?

The WWF must need some money. Donations always pick up after a news release.

It is a true statement about the temperature rise is needed for more ice to melt. The problem is it's been colder (worldwide) the last year and still setting record temps in many parts of the planet. Didn't happen to see that mentioned in their article, guess it goes against what they are for.

Seems that scientific evidence is pointing towards planetary cooling instead. Time will tell who is right.

Gee I have tracked my local temp for a couple months and we are on average 4.03 degrees F below normal this fall for the last ten days we are 11.1 degrees below normal. Does that mean we are going into an Ice Age??

And if a froghad a propeller in its behind it might mean it is a submarine.

Stop it with the Global Climate disaster stuff. We are not warming.

A lot of others say different – do you have proof that we are not warming.
I suppose there’s a conspiracy angle is there?

Great. Only 2° to get back to where we were from AD800-1200.

Vikings travelling to Iceland from Norway during the MWP were probably encouraged by the sight of pastures with sedges and grasses and dwarf woodlands of birch and willow (Fig. 14) resembling those at home.

Animal bones and other materials collected from archaeological sites reveal Icelandic Vikings had large farmsteads with dairy cattle (a source of meat), pigs, and sheep and goats (for wool, hair, milk, and meat.) Farmsteads also had ample pastures and fields of barley used for the making of beer and these farms were located near bird cliffs (providing meat, eggs, and eiderdown) and inshore fishing grounds. Fishing was primarily done with hand lines or from small boats that did not venture across the horizon (McGovern and Perdikaris, 2000.)

So maybe CO2 is a good thing after all... wait, maybe it's not CO2...

THE deep ocean continues to surprise: it appears a volcano on the seabed has exploded with a force thought impossible.

...

To find out what caused it, Robert Sohn of the Woods Hole Oceanographic Institution, Massachusetts, and colleagues peeked at the ridge with a remote-controlled device. They found shattered rock spread over 10 square kilometres, suggesting a series of volcanic explosions (Nature, vol 453, p 1236).

OK, maybe we got it wrong. Instead of CO2 levels increasing slightly and boiling away the ice that has existed for infinity in Greenland, volcanic activity under the ocean floor heated the ocean, melting the ice, and returning Greenland to what it was a scant few thousand years ago.

Wow, does anyone have any idea how the planet survived that catastrophic farming in Greenland? Maybe they had carbon credits back then? I haven't been able to find a source on them...

Hi Redneck - Thanks for that.
I visited those sites very interesting you learn something new each day. Reading other posts some people are saying its getting colder but I think it depends where you are we are definitely feeling warmer and wetter in my neck of the woods.

mmmm WWF

anyhow very important,

I just posted A LOT MORE real research on Glaciers to include the links to the Greenland, one in this thread that dovetail nicely with this thread, please do look if you want to know what is really going on, and what all that fresh water in the oceans means:

Tibetan Glaciers Melting at an Alarming Rate

Kind regards,

Elf.

Yea I'll go a take a look
Have you seen this

US scientists have figured out how icebergs break off Antarctica and Greenland, a finding that may help predict rising sea levels as the climate warms.

Yeah, we always called that phenomena 'weather'.

I personally am not overly concerned about warming or cooling on a global scale. The variations we have seen may make for some good headlines, but they do not seem to me to be out of the ordinary. The atmosphere is a chaotic system driven by so many variables and regulatory systems that all anyone can really do is watch and go 'wow' anyway.

Wait, there is something one can do, and you picked up on it. Learn.

I'm there, thanks for the tip.

yes, a 2 degree Celcius rise, globally, would practically wipe out third-world agriculture as we know it, and therefore most of the third-world itself...

but then again, TPTB have known this for quite a long time, and it goes right along with their plan of reducing the world's population... you don't think they know that carbon emissions heat up our planet?!! they've been carrying out this plan for a long time, all-the-while trying to make us think there's nothing significant that we can do about it...

they've forced us to play by their rules and use their fossil fuels to run our caveman technology, but their rules defy nature's...

did we actually think nature wouldn't kick back?!...

That's a reliable source though you have to admit.

Maybe I've been growing things wrong, but last time I checked, a rise in temperature actually helped increase agriculture. Isn't that why we grow crops during the warmer months?

Or am I misunderstanding you?

Global warming is actually just a horrible term. The theory in itself can cause the highs and the lows to be more extreme along with a higher average temp. So with this you can get a colder winter in some parts of the world and a extremely hot summer.

I can see how people say global warming isn't true but it would be hard to deny the evidence that the worlds climate as we know it is changing drastically compared to what it has been over say the last 100 years.

www.independent.co.uk...

MYTH: Recent cold winters and cool summers don’t feel like global warming to me.

FACT: While different pockets of the country have experienced some cold winters here and there, the overall trend is warmer winters.

Measurements show that over the last century the Earth’s climate has warmed overall, in all seasons, and in most regions. Climate skeptics mislead the public when they claim that the winter of 2003–2004 was the coldest ever in the northeastern United States. That winter was only the 33rd coldest in the region since records began in 1896. Furthermore, a single year of cold weather in one region of the globe is not an indication of a trend in the global climate, which refers to a long-term average over the entire planet.

firstly I am a little surprised at the um factor directed towards WWF...

any reason why people now have attitude with this organisation?

secondly, I think the real issue here is in the final sentence of the article:

"Responsible politicians cannot dare to waste another second on delaying tactics in the face of these urgent warnings from nature."

Have you been reading the news???????

It's getting COLDER!!

lol

Cant have it both ways, son.

Global Warming is a terrible term, agreed. What I do not agree on is your reasoning. In reference to your first link, please see my last post. It covers the freshwater influx into the Gulf Stream and explains how the situations are not equivalent, even if Greenland melted completely. Colder winters in Britain? Maybe, a little. Life-threatening, civilization-ending cold? Nah, not quite. Do the math and it'll show you why.

As to your second link, it lost me with this (the very first lines):

MYTH: The science of global warming is too uncertain to act on.

FACT: There is no debate among scientists about the basic facts of global warming.

Source: www.edf.org...

This is not a fact. There are plenty of scientists who disagree with 1) the assumption that recent warming trends will continue, 2) the assumption that we re even still on a warming trend, 3) the assumption that the warming trend is man-made, and 4) the assumption that any warming is caused by CO2 levels. A quick search of ATS alone will give you several treads about prominent scientists who have come out publicly challenging the AGW assumptions.

The rest of the article, which is published by the Environmental Defense Fund, reads more like a blog than a scientific data report. There are no hard facts specified, only generalizations, assumptions, and interpretations disguised as such.

On a happy note, I just came across a thread here that appears to possibly have a solution to the question of why other planets are also showing slight warming trends. The title may be fanciful, but read through the information and you will see that there are quite possibly other forms of heating than 0.038% atmospheric CO2 levels.

A quick appetizer from the source for that thread:

Nov. 19, 2008: An international team of researchers has discovered a puzzling surplus of high-energy electrons bombarding Earth from space. The source of these cosmic rays is unknown, but it must be close to the solar system and it could be made of dark matter. Their results are being reported in the Nov. 20th issue of the journal Nature.

I wish I could have found a better link because I agree that a few things were not the best on there. They did have some decent info on why a colder winter could happen with " Global warming". Turkey and lack of sleep makes me lazy so I will stick with what I posted.

I also have already read the link you posted previously and thought it was interesting. I wish they wouldn't have made it sound like aliens were beaming these to our planets although that could also just be my personal bias forming from the information given. I believe in aliens but I have a hard time wrapping my head around them beaming those into the atmosphere and I can't think of other ways for them to currently get there except maybe something like mini black holes in dark matter and we are getting whats sucked through. ( Yes I realize that's not very logical lol)

I also think that the flipping of the magnetic poles could be playing a gigantic part in the weather phenomenon we are currently experiencing. We can call it global warming or a natural cycle but either way it could have catastrophic results for life on our planet.

You get a star for your post because you called out my laziness in my link choices.
