Ancient Vikings once farmed land in Greenland that is now covered with ice more than 1 mile thick...?

Question

Doesn't this suggest that global warming/cooling is naturally cyclictic without any influence by human activity?

Do you believe that "global warming" as it is viewed today is purely a fabrication driven by political agenda? Is this planet's historical, factual, climactical data being largely and conveniently ignored by left wing alarmists trying to sell us snake oil?

I think so too.

Answer 1

Actually farming has started up again in Greenland. It isn't ALL covered by ice. It never was. There was always some coastal land ice free in summer, and now it is warm enough for some farming to be done again.

Answer 2

"Doesn't this suggest that global warming/cooling is naturally cyclictic without any influence by human activity?"

Even if your statement (for which you provide zero evidence) were true, no, it would not suggest this.  Not remotely.  Why would it?

The rest of your question is paranoid conspiracy theory garbage.

Answer 3

Sure and Antarctica used to have tropical plants

one time the planet had 60 % carbon in the atmosphere

nobody could breathe then.

and England once was tropical as well

So what

what has any of that got to do with today and Global warming,

there are Natural fazes but we are affecting that to a great extent ,with deforestation ,desertification and pollution., especially air pollution.

A few weeks ago one of NASA's top scientists concluded that the Arctic Ocean could be nearly ice-free within five years, much faster than all previous predictions.

Calculations do not include the accumulative ,speeding up ,factor with time. the increase in water temperature will get faster all the time as well as the melting, when the ice is all gone the deeper cold Ocean currents will stop ,and the drag has gone with it ,also changing the higher warm currents,And only the moon and the planet revolving around the sun,will keep things moving

This will affect coastal climates ,world wide ,almost instantly. All aquatic flora and fauna will be affected,many dying off and others becoming invasive,

And recently In Chiapas ,and Tabasco in Mexico .more then a million people became homeless overnight with water coming up to their roofs ,because of rains from super evaporation from the forests,this had never happened before. Millions of animals died.

In India 3000 people died because of super storms .

.A few years ago in Europe 3500 people,died during a heat wave ,many of them in France .

Right now the average death toll annually is 150.000 due to Global warming

. these figures are already out of date and are expected to double soon.

In Northern China millions of people are running for their lives because regular dust storms so far have buried 900 villages under the sand and the whole of northern China is turning into a dessert.

The Sahara is growing by 7 kilometers a year all around the edges ,like a slow burning fire shriveling up their neighbors In the Kalahari huge rivers have dried up and thousand of species are gone due to their habitats disappearing .

The biggest changes are invisible at micro biotic levels species are becoming extinct ,others are multiplying ,

This affects the insect populations that follow ,and changes in that ,affect all that follows in the food chains ,

All life is interrelated of both flora and fauna, And since we are on the top of the food chain ,

we are always the last to know.

So Global warming has its toll there are incidents all over the world ,

However

confusion rules the day ,i am beginning to think that SCIENCE HAS BEEN INVADED WITH POLITICS AND HUMAN EMOTIONS

The truth is being distorted at high levels,

And lies have been weaved in.

Some of the real dangers are being hidden because there are no solutions , Public could panic.and Authorities would loose control .

Besides Corporations have other priorities and changes will cause loss of profits ,this also affects the truths being published

Others facts are exaggerated so that the phenomena can be used to milk the people.

This is further complicated with Arrogance that will not admit that mankind could be guilty, or that Gods could be out of control ,unloving or incompetent

But I do not think we can make a real difference anymore to change the tide.

On a Global scale,Humanity is not co operative enough .

The poor regions have other priorities such as daily survival.

There is a lot we can do about being more responsible with what we got ,and we could pollute less

But

In the first world countries many do not care or are more interested in Global Control than Global Warming.

Answer 4

I read Campbelp's answer and I would suggest that YOU are the one who did not understand.

The areas that the Vikings farmed (little pockets around the coasts) are not under a mile of ice (as you did write) - they are actually completely ice free in the summer.  The Vikings died/left when their growing seasons became too difficult.

And no, your assumptions about GW are not correct. That warm spell was very minor and short lived. Sure it was natural. But it does not mean that humans can not have a HUGE impact through their activities.

EDIT: What facts are you referring to?

Seriously, don't you think it's time to be honest enough to admit that you don't/didn't know what you're talking about when you asked this question?

Everyone makes mistakes, the brave admit it.

Answer 5

If you want a serious response, post serious evidence. Making wild unsupported assertions only make you look ignorant.

There is no land in Greenland currently covered by ice 1 mile thick that was farmed by the Vikings.

Answer 6

I also agree with campbelp.  It is true that viking living communities are now being reviled, but no they were not under a mile of ice. There has not been enough time for a mile of ice to freeze or thaw.  that amount of freezing would take a lot longer than that.  There is also not enough time for the mile of ice that is still there to thaw over that next hundred years.  you are correct Greenland has been this warm many times but this does not prove nor dis-prove the man-made part of climate change.

Answer 7

i dont even know what your talking but i got 2 points :)

Answer 8

The Norse (they stopped going viking and settled down to farm) didn't farm on the glacier.  They farmed on the southern and westerns edges of the great island that is Greenland.  The glacier existed then as it does now, covering most of the interior.

The Norse ended up abanonding their settlements in Greenland because they destroyed the land.  The topsoil wasn't that thick to begin with an allowing goats and sheep to graze it caused enough erosion that they couldn't grow crops anymore.  

The book "Woven in the Earth" while mostly about the textiles found in the Norse graves in Greeland also has some great information about the skeletons and how malnourished the Norse were before they finally gave up and returned to Iceland.

Answer 9

Disclose your source for that information.  It's laughably absurd.  (A mile of ice sheet doesn't form then thaw that quickly.)

What was found deep below the ice were genetic traces of butterflies, moths, flies and beetles.  The material was recovered from cores drilled through ice 1.2 miles thick at a site called Dye 3 in south central Greenland, and it dates from 450,000 to 800,000 years ago, not the period from From AD 984 to the 15th century when Norse settlers were there.

It would be comforting to believe that global warming was some sort of conspiracy, wouldn't it?  Unfortunately the evidence doesn't suggest or support that conclusion.

Past global warming and cooling cycles have been examined and are part of the basis for our understanding of current global warming (as well as the temperatures of Venus and Mars, based on the component of greenhouses gasses in their atmosphere).  So you're on the right track to consider past cycles and their causes, but your conclusion conveniently ignores the science and the evidence.

"It is interesting to note that in the absence of a greenhouse effect, the earth’s mean temperature would have been 255°K, instead of the observed value of 288°K. Greenhouse warming is thus about 33°K.  This is much more pronounced around the planet Venus, whose atmosphere contains over 90% carbon dioxide (CO2), a prominent greenhouse gas. Without a greenhouse effect the mean surface temperature of Venus would have been 227°K, but greenhouse warming raises it to 750°K. This represents warming by 523°K!"

You may believe whatever unsubstantiated theory makes you feel good, but the warming, melting, and sea level rise will continue.  In fact, it's accelerating.

Edit - You chastise people about "facts"... so where are yours?  Offer even one link to anything of any substance!

Answer 10

Vikings once farmed the exact same land in Greenland that is farmed today.

That shows that the anti-global warming nuts are, well nuts.
