It's called GREENland because it was Green when it was discovered. This has happened before in human history, even just since history started being kept. It's part of earth's cycle.

I won't argue whether people are speeding it up, etc. - but even if every human being had a zero carbon footprint & never produced any trash, this would still happen.

You are miss reading the facts

online.wsj.com...


On average, about half of the surface of Greenland's ice sheet naturally melts during the summer, and then mostly refreezes with the approach of winter. This year, nearly the entire ice cover, from its thin, low-lying coastal edges to its two-mile-thick center, experienced some melting at its surface, according to measurements from three independent satellites analyzed by NASA and university scientists.

"This summer, we have seen melting at the very highest elevations of the Greenland ice sheet, which we have not seen before in the satellite record," said climatologist Thomas Mote of the University of Georgia, who studies snow cover. Researchers expect much of it to refreeze.


Only the surface of Greenlands 2 mile thick ice sheet melted, if that two mile thick sheet melts, lots of people would be getting more than their feet wet.

Hey, you can do what you want, I'm watching this one. Antarctica isn't going to wait for Greenland to finish melting.

The cooling cycle should have happened already, it didn't. something is screwed up. This isn't a natural time for this to occur, we are a thousand years too early. We cannot even predict what is going to happen anymore using past evidence.

Yes. Whether what is happening is good or bad or why it is happening or whose fault it is or isn't doesn't matter. The point is what's happening is happening because this is what happens to be happening at this time.

By the way is your avatar "Gog"?

Sometimes I'm amazed that there's any natural, untouched, habitat left on the earth when you realize what out of control polluters people are.

The oceans rising is just part of the problem. It's going to happen, we just don't know how fast.

The bigger question to me is what kind of climate changes are we going to see.

Those large area of salty water must be keeping the hurricanes down, what will become desolate desert, and what will see 100" plus annual rain fall.

It is going to get crazy.

Piri Reis Map


I think those maps are genuine because when they were discovered(think it was about 1500's) we didn't even know the arctic existed.
edit on 22-9-2012 by VoidHawk because: (no reason given)


The maps in question showed the antarctic coastline as it appeared as much as 12,000 years ago when it was not covered in ice. The maps were shown to be accurate when we were able to use ground penetrating radar and other methods of seeing under the ice.

Some of the maps were too modern to have been drawn that long ago but the legends on the maps referenced much older maps, since lost to time and age, that did show the coastline as it appeared that long ago.

This seems to support the truly ancient civilizations and/or ancient alien visitations.

I wonder what we will find if we ever do get a good look at Antarctica without it's miles deep ice cover. There are speculations that sometime in the far distant past civilizations were destroyed because of a planetary crustal shift. There are several theories as to what would have caused that shifting of the crust but to go too deeply into them on this thread would lead it too far off topic.

That's a direct lie.

It's recorded in Nordic history, and Scandinavian history shows numerical cycles of this nature.

The Greenland glacier shows a 180 year warming cycle. During this cycle, Greenland was "green" and habitable. And during this time, people were growing corn in Iceland. Even with today's climate change, Iceland still needs some +5 more degrees on average to reach the same point it had a thousand years ago.

Sweden shows numerical climate changes. 4 thousand years ago, Sweden was tropical ... yes, tropical.

I'm really tired of reading such blatant lies.

What kind of changes. Therein lies the $64 question. It has begun and continues. Something(s) will come to pass. And seeing as how everything affects everything else the possibilities are endless and cannot be fore-casted with any degree of certainty.

THe most pressing thing in our times?... really?...

Was "Global Warming" "the most pressing thing" to the Vikings when the ice was even more receeded than it is now?....

Was "Global Warming" "the most pressing thing" in the times of the Romans during the Roman Warming period when it was WARMER GLOBALLY than it is now?....

Was "Global Warming" "the most pressing thing" in the Medieval Warm Period when it was WARMER GLOBALLY than now?...

Are disasters going to happen and increase?... YES, it has happened many times and it is NATURAL...

The MOST "pressing thing" in our time is to "ADAPT" to the NATURAL CHANGES that are occurring... Just like the Vikings did it, just like during the Medieval and Roman Warming PEriods and a myriad of other warming periods and cooling periods which have occurred...

Read the sources from the fist page. The ice has retreated to the point where ancient forests covered by ice for millions of years are now being exposed.

Ice on Greeland has retreat beyond where it was during the time of the Vikings, within a decade. The historical record shows that we are heating up faster then ever before.

You want to ignore this, it's your choice.

Not too long ago global cooling was the name of the game with scientists having data to back that up. Even if it does happen we will adapt.

People should stop making comparisons to today's polar ice levels with the mini Ice Age that began in the 1800s and we've been exiting for a while.

Search for Medieval, and Roman Warm Periods...

Search for Climategate and how the main scientists behind the LIE of "mankind is at fault for Global Warming/Climate Change" have been caught red handed several times in their lies and deceipt, and because most people, like yourself, are completely ignorant and don't do proper research, people like you don't find out the truth...

This has been the SAME lie that mainly leftwingers have been claiming for decades, but the truth is that temperatures during the MEdieval Warm Period had been from 1 to 3 degrees HOTTER than even at present, and the Roman Warm Period was even warmer...

Temperatures have not increased 1-3 degrees since 1998, hence it is another LIE that "today is hotter than ever before"...

CWP = Current Warm Period, MWP = Medieval Warm Period, and RWP = Roman Warm Period.




The above graphic is from an analisys of sediment from the Wrangell-St. Elias National Park and Preserve of south-central Alaska (USA)

BTW CWP stands for "Current Warm Period" and you can see that both the Medieval, and Roman Warm Periods were warmer than the most current warm period.

The following is a graph from the Sargasso Sea Temperature reconstruction.



Although this article explains that evidence of the RWP in Asi is being disputed, it does say that and I quote:

Moreover, the impact of the RWP to the East Asian ancient history is not clear also because there were no notable political factions in all East Asia except in some parts of China.


This bears great relevance because the RWP weather events weren't reported as much as other Climate Change events.

However if you take a look at this graph, which show the Climate Changes in East Asia for the past 1,800 years you can see that at least part of the Medieval Warm Period was warmer even than the present, and they even mention it.


II.2.3 The Medieval Warm Period
After the DACP was another warm period that continued until c. 1350 A.D., and it was wet and warm again like the RWP. Although some scientists argue that actually there was no significant warm climate during the MWP in East Asia, it seems evident that at least the 12th century was warmer than any other periods - even warmer than today-discussed on this paper.

Title: Torneträsk tree-ring width and density ad 500–2004: a test of climatic sensitivity and a new 1500-year reconstruction of north Fennoscandian summers

Abstract: This paper presents updated tree-ring width (TRW) and maximum density (MXD) from Torneträsk in northern Sweden, now covering the period ad 500–2004. By including data from relatively young trees for the most recent period, a previously noted decline in recent MXD is eliminated. Non-climatological growth trends in the data are removed using Regional Curve Standardization (RCS), thus producing TRW and MXD chronologies with preserved low-frequency variability. The chronologies are calibrated using local and regional instrumental climate records. A bootstrapped response function analysis using regional climate data shows that tree growth is forced by April–August temperatures and that the regression weights for MXD are much stronger than for TRW. The robustness of the reconstruction equation is verified by independent temperature data and shows that 63–64% of the instrumental inter-annual variation is captured by the tree-ring data. This is a significant improvement compared to previously published reconstructions based on tree-ring data from Torneträsk. A divergence phenomenon around ad 1800, expressed as an increase in TRW that is not paralleled by temperature and MXD, is most likely an effect of major changes in the density of the pine population at this northern tree-line site. The bias introduced by this TRW phenomenon is assessed by producing a summer temperature reconstruction based on MXD exclusively. The new data show generally higher temperature estimates than previous reconstructions based on Torneträsk tree-ring data. The late-twentieth century, however, is not exceptionally warm in the new record: On decadal-to-centennial timescales, periods around ad 750, 1000, 1400, and 1750 were equally warm, or warmer. The 200-year long warm period centered on ad 1000 was significantly warmer than the late-twentieth century (p < 0.05) and is supported by other local and regional paleoclimate data. The new tree-ring evidence from Torneträsk suggests that this “Medieval Warm Period” in northern Fennoscandia was much warmer than previously recognized.

Abstract

The Little Ice Age, from around 1300 to 1800, and medieval warming, from before 1000 to around 1300 in South Africa, are shown to be distinctive features of the regional climate of the last millennium. The proxy climate record has been constituted from oxygen and carbon isotope and colour density data obtained from a well-dated stalagmite derived from Cold Air Cave in the Makapansgat Valley.
The climate of the interior of South Africa was around 1oC cooler in the Little Ice Age and may have been over 3°C higher than at present during the extremes of the medieval warm period. It was variable throughout the millennium, but considerably more so during the warming of the eleventh to thirteenth centuries. Extreme events in the record show distinct teleconnections with similar events in other parts of the world, in both the northern and southern hemispheres. The lowest temperature events recorded during the Little Ice Age in South Africa are shown to be coeval with the Maunder and Sporer Minima in solar irradiance. The medieval warming is shown to have been coincided with the cosmogenic 10Be and 14C isotopic maxima recorded in tree rings elsewhere in the world during the Medieval Maximum in solar radiation.

Evidence for the existence of the medieval warm period in China

Abstract The collected documentary records of the cultivation of citrus trees andBoehmeria nivea (a perennial herb) have been used to produce distribution maps of these plants for the eighth, twelfth and thirteenth centuries A.D. The northern boundary of citrus andBoehmeria nivea cultivation in the thirteenth century lay to the north of the modern distribution. During the last 1000 years, the thirteenth-century boundary was the northernmost. This indicates that this was the warmest time in that period. On the basis of knowledge of the climatic conditions required for planting these species, it can be estimated that the annual mean temperature in south Henan Province in the thirteenth century was 0.9–1.0°C higher than at present. A new set of data for the latest snowfall date in Hangzhou from A.D. 1131 to 1264 indicates that this cannot be considered a cold period, as previously believed.

Decline Of Roman And Byzantine Empires 1,400 Years Ago May Have Been Driven By Climate Change

ScienceDaily (Dec. 6, 2008) — The decline of the Roman and Byzantine Empires in the Eastern Mediterranean more than 1,400 years ago may have been driven by unfavorable climate changes.

Based on chemical signatures in a piece of calcite from a cave near Jerusalem, a team of American and Israeli geologists pieced together a detailed record of the area's climate from roughly 200 B.C. to 1100 A.D. Their analysis, to be reported in an upcoming issue of the journal Quaternary Research, reveals increasingly dry weather from 100 A.D. to 700 A.D. that coincided with the fall of both Roman and Byzantine rule in the region.

www.sciencedaily.com...

In fact, as I have pointed out before with other research, the Earth has been warmer than during the 20th, or the beginning of the 21st century, yet CO2 levels in the atmosphere were much lower than now.

Such dramatic Climate Changes occurred globally, not just in one area, or just in the northern hemisphere.

Abstract
We reconstruct environmental conditions of coastal Northwestern Florida from combined measurements of δ18O and Sr/Ca of fossil marine bivalves deposited in an archeological site during the late Holocene period. We first investigated the environmental controls of seasonally resolved records of δ18O and Sr/Ca of modern Mercenaria mercenaria and Mercenaria campesiensis collected live from five coastal sites along the east coast of North America. Seasonal profiles were obtained by sub-sampling the incremental growth layers of aragonite and were compared with in situ historical records of temperature and salinity. We show that these bivalves precipitate their shell in isotopic equilibrium with the water in which they grew and that the δ18O records are not affected by variations in growth rate. Winter growth appears to be interrupted or strongly reduced below water temperatures ranging from 7 to 18° C, depending on latitude. The annual average δ18O decreases with latitude, reflecting both the parallel trend of freshwater δ18O with latitude over the North American continent and the reduced winter growth rate. The Sr/Ca records of the 5 modern bivalves also exhibit seasonal variations can be correlated to water temperature. However, contrary to corals, the Sr/Ca ratio is considerably lower than the average sea water Sr/Ca composition and is positively correlated to the water temperature. We dated and measured the δ18O and Sr/Ca of 30 fossil M. campesiensis from an archeological site close to Cedar Key, in the Gulf of Mexico. Accelerator Mass Spectrometry 14C dates obtained for each shell show ages which cluster between 1100 to 1400 and 2300 to 2600 14C years BP corresponding approximately to two historical warm periods known as the Medieval Warm Period (~ 1300-900AD) and the Roman Warm Period (~ 250AD-200BC). The average annual and summer Sr/Ca of 4 fossil shells are higher than that of modern bivalves from the same location suggesting that annual coastal water temperatures were 3 to 4° C warmer than today. The bulk δ18O values show a marked trend towards more positive values. 24 fossil shells have bulk δ18O values 0.2permil to 0.7permil more positive than modern bivalves from the same location. These results suggest that the coastal waters off northwest Florida were warmer and less saline compared to today and attest of considerable differences of the regional climate and hydrological balance during the Medieval Warm Period and Roman Warm Period.

But hey according to Essan "it wasn't", and of course he gives no real evidence and he gives no conclusive proof that the dozens of research are wrong which say the contrary to his own "beliefs"...

As to what could have been the reason for Climate Changes such as "Global Warming":

Galactic energy and its role in a changing Earth

--------------------------------------------------------------------------------
ALAN P.M. VAUGHAN


Proposed climate change mechanisms are many and various but generally attributable to our part of the solar system. They usually focus on temperature changes driven either by local processes such as variations in oceanic circulation, or, levels of atmospheric greenhouse gases such as carbon dioxide, or by global processes such as variations in received solar energy linked to changes in the parameters of the Earth's rotation and orbit or solar activity. However, two recent papers have suggested that we may need to look outside the Earth System and even outside our local planetary system for the possible origins of climate change, both on a decadal scale and over longer timescales of hundreds of millions of years. In each case, the galactic cosmic ray flux and its potential effects on cloud formation is considered to be the culprit.



journals.camb ridge.org

The above are just osome of hundreds of peer-review research papers, from thousands of scientists who have linked Solar System and Galactic events, among other NATURAL events as the causes of the Climate Changes we have been experiencing.

No, Greenland was one of the first examples of a marketing ploy. It was called Greenland to encourage people to move there. But was far less green than Iceland was at the time.

Both Iceland and some coastal parts of Greenland were forested until the Vikings came along and chopped all the trees down. Neither place has recovered.

Nor has Easter Island.

Grazing livestock add to the problem, eating any seedlings.
