Massive Iceberg About to Break Off Antarctica

An iceberg the size of Delaware is poised to break away from Antarctica, an event which may lead to the collapse of a massive ice shelf on the continent, according to researchers...........
......In response to expressions of concern on social media, MIDAS scientists responded that there was no need for alarm. "This is a fairly normal event, although it is spectacular and quite rare."

The site is useful for the numbers.
They are updated rapid fire.
The part you quoted hasnt changed for as long as Ive been checking the page.

Years.

Look at the actual data.
Greenlands ice sheet is growing extremely fast this year.

Is that what your twitter master told you?

Childish.
Look at the 2000 to 2013 average and compare it to the 16-2017 graphic.,

Scroll down to the bottom of the page and see the explanation of your quote.
Its been a part of that page for at least five years.
My guess is that its part of a funding requirement.

Your guess?
 
Interesting weather effects --

http://www.intellicast.com/National/Radar/Current.aspx?location=USNY0124&animate=true

The blue bands running southeast from the Great Lakes are lake effect snow, caused by cold air blowing over the open water surface, picking up moisture, and dumping it over land downwind. Later in the year, after the lakes have frozen over, there is no more lake effect snow.

The waters around Greenland have been seeing decreasing ice coverage and warmer air temperatures over the last few decades, which leads to a similar effect.

Knowledge of this is nothing new. It is not likely, however, to show up in any climate-change denier twitter feed.

Why the childish tone?
The information I posted is accurate and up to date.
I dont know why they havent updated their text in years, but the daily data is very good.
The data shows the ice sheet was at its low point 2012 -13.
This season is much cooler than last, probably due to carbon credits.

Are we looking at the same page? I don't see any data for the ice sheet in 2012-2013. I also don't see "this season is much cooler that last".

We hiked up Mount Sunday, home of the Rohan village in the Two Towers and Return of the King. While there we were treated to a cattle round up from on top Mt. Sunday. The Foreman dispatched three sheep dogs and a German Shephard by dog whistle. It was amazing to watch the dogs work. Whatʻs not so amazing is that the NZ government started subsidizing cattle for dairy when the Chinese rescinded their planned parent hood laws. The NZ central government increased the money supply for dairy farming thinking that demand would always be more than supply. Can anyone guess what happened when farmers were allowed to borrow according to government projections?

My mistake. I meant to put 2011-12.

The line labeled 2011-2012 is to show a year of heavy melting. Each line on that graph are one year of snow falling and melting - most years there is a net accumulation (the right end of the line is above 0). The weight of that accumulating snow is why the ice spreads out to the margins where the icebergs calve off, resulting in the 200 Gt/year net mass loss.

All of those facts are included on that page. Also on that page is a copyright date of 2014, which is not 5 years ago.
 
The climate cycle:


Climate helped drive Vikings from Greenland
Greenland's early Viking settlers were subjected to rapidly changing climate. Temperatures plunged several degrees in a span of decades, according to research from Brown University. A reconstruction of 5,600 years of climate history from lakes near the Norse settlement in western Greenland also shows how climate affected the Dorset and Saqqaq cultures. Results appear in Proceedings of the National Academy of Sciences.

.....What climate scientists have been able to ascertain is that an extended cold snap, called the Little Ice Age, gripped Greenland beginning in the 1400s. This has been cited as a major cause of the Norse’s disappearance. Now researchers led by Brown University show the climate turned colder in an earlier span of several decades, setting in motion the end of the Greenland Norse. Their findings appear in Proceedings of the National Academy of Sciences.
.....“The record shows how quickly temperature changed in the region and by how much,” said co-author Yongsong Huang, professor of geological sciences at Brown, principal investigator of the NSF-funded project, and D’Andrea’s Ph.D. adviser. “It is interesting to consider how rapid climate change may have impacted past societies, particularly in light of the rapid changes taking place today.”
.....“You have an interval when the summers are long and balmy and you build up the size of your farm, and then suddenly year after year, you go into this cooling trend, and the summers are getting shorter and colder and you can’t make as much hay. You can imagine how that particular lifestyle may not be able to make it,” D’Andrea said.
....The researchers also examined how climate affected the Saqqaq and Dorset peoples. The Saqqaq arrived in Greenland around 2500 B.C. While there were warm and cold swings in temperature for centuries after their arrival, the climate took a turn for the bitter beginning roughly 850 B.C., the scientists found. “There is a major climate shift at this time,” D’Andrea said. “It seems that it’s not as much the speed of the cooling as the amplitude of the cooling. It gets much colder.”
