sounds crazy eh!
Evening mate!
I found these 2 lots of information about Greenland and it's name.
The name Greenland (Grønland) has its roots in this colonization and is widely attributed to Erik the Red (the Inuit call it Kalaallit Nunaat, "Our Land"), and there has been speculation on its meaning. Some have argued that the coasts in question were literally green at the time due to the medieval climate optimum, in as much as the Viking settlers practised some form of an agrarian economy. Others have suspected that the name was in part a promotional effort to lure people into settling there by making it sound more attractive. The condition of Greenland in the 10th century may have been more hospitable than today.
The population of Greenland in the 12th Century was 10,000 - and these would have had to feed themselves. And that refers to Viking settlers. According to http://www.greenland-guide.gl/leif2000/history.ht m the Inuit only appeared on the coasts around 1350 - around the time of the abandonment of the Western coast settlements. This indicates (to me, at least) that the climate was changing and the Viking way of life wes becoming unsupportable, while the Inuit way was able to succeed. The Inuit would have been further north during the climatic warming, and returning south as the conditions worsened.
Breakfast's on the sideboard: Steak and eggs, oatmeal with brown sugar, yogurt, fresh fruit and orange juice. Enjoy!
Moisture increases today and peaks tommorow as a trough moves close to PR.

AFOREMENTIONED TROUGH AND ASSOCIATED SURFACE FRONT APPROACH THE
LOCAL AREA. HIGH PRESSURE WILL BUILD ACROSS THE AREA EARLY NEXT
WEEK.

.DISCUSSION...CLOUDINESS WITH SHOWERS HAVE BEEN MOVING ACROSS THE
SOUTHERN HALF OF PUERTO RICO OVERNIGHT. SHOWERS WILL CONTINUE THIS
MORNING AFFECTING THE LOCAL AREA FROM TIME TO TIME...AS PATCHES OF
LOW LEVEL MOISTURE MOVES ACROSS THE AREA. LATEST SATELITE IMAGES
AS WELL LATEST TPW PRODUCT FROM CIMMS ARE SHOWING AN INCREASE IN
MOISTURE ACROSS THE REGION. THIS WILL RESULT IN WETTER

UPPER LEVEL TROUGH WILL MOVES ACROSS THE WESTERN ATLANTIC TONIGHT
AND FRIDAY. THIS SYSTEM IN COMBINATION WITH DAYTIME HEATING AND
LOCAL EFFECTS WILL AID IN THE DEVELOPMENT OF SHOWERS AND POSSIBLE
THUNDERSTORMS FRIDAY AFTERNOON. A DRIER TREND IS THEN EXPECTED

Only 15% probabilities now due to model differences, but their discussion hinted at these probabilities going up once details become more clear. Damaging wind will be the biggest threat with isolated tornadoes also possible.

Natural Climate Swings Contribute More to Increased Monsoon Rainfall Than Global Warming
Mar. 20, 2013. Natural swings in the climate have significantly intensified Northern Hemisphere monsoon rainfall, showing that these swings must be taken into account for climate predictions in the coming decades, a new study finds.
...Current theory predicts that the Northern Hemisphere summer monsoon circulation should weaken under anthropogenic global warming.
Wang and his colleagues, however, found that over the past 30 years, the summer monsoon circulation, as well as the Hadley and Walker circulations, have all substantially intensified. This intensification has resulted in significantly greater global summer monsoon rainfall in the Northern Hemisphere than predicted from greenhouse-gas-induced warming alone: namely a 9.5% increase, compared to the anthropogenic predicted contribution of 2.6% per degree of global warming.
Most of the recent intensification is attributable to a cooling of the eastern Pacific that began in 1998. ...

Significant Contribution of Greenland's Peripheral Glaciers to Sea-Level Rise
Mar. 18, 2013. Glaciers at the edge of Greenland which are not connected to its huge ice sheet, or can be clearly separated from it, are contributing to sea-level rise much more than previously thought. Scientists from the University of Zurich together with colleagues from Denmark have found that, though these peripheral glaciers make up just 5-7 % of total ice coverage on the land mass, they account for up to 20% of the rise in sea level created by the region's melting.

Everyone have a great Thursday. Aussie, have a great Friday!
This storm system is heading my way tomorrow. Let's hope it's lost a lot of energy by the time it get's here. Of course I'll keep everyone informed.
1st reports coming in now.
Tornados tear through Victorian towns
Several tornados have ripped through parts of Victoria's north-east, destroying buildings and injuring several people.
The State Emergency Service (SES) says at least two tornados moved between Cobram and Yarrawonga about 8:00pm (AEDT) this evening.
Lachlan Quick from the SES says there have been a number of injuries.
He says Rutherglen was one of the most badly affected towns and a number of buildings have been affected.
"I know there are quite a lot of holiday homes that are unoccupied and that may have assisted us with fewer injuries," he said.
"But certainly at his stage it's very busy up there and we are issuing further volunteer units up there at the moment."

The latest update from NSW SES State Headquarters states:
NSW SES Update from southern NSW.
In Barooga up to 80% of the Golf Hotel roof has been dislodged. Trees on several vehicles along Golf Course road. Reports of homes damaged. The Post Office roof has been dislodged. Cobram-Barooga Golf Resort %u2013 extensive roof damage.
At Mulwala township near Corowa a caravan park has had several vans blown over. At Kissins Reserve camp site %u2013 multiple caravans blown over. NSW SES and Fire and Rescue on scene.
More updates as they come to hand. If you are driving in the Riverina area or NE Vic be aware trees may be down on roads.
Seriously? Grant money and greedy college professors? This whole rant comes off as little more than anti-intellectualism and a lack of knowledge about science. I actually don't feel like arguing with you; I honestly just feel sorry for you.
If the current AO index -5.2 is linked to Arctic sea ice loss, then what the AO -6.3 in March 1970 is linked to? Too much ice? There was more than 80% more ice at that time, right?
Also why this unusual winter jet stream pattern has to happen at 80% ice loss and didn't happen at 40% or 79.99% loss?
