Another dumb thread, by a dummy.

Remember the Vikings? They had settlements on Greenland oh so long ago...I wonder how they could get there and live there, before AGW destroyed the planet.

What is an ice core?

In memoriam. This essay is dedicated to the memory of John Wahr8 (June 1951 - November 2015) for his exceptional contribution to studying and promoting the understanding of the interactions between the solid layers of the Earth and the overlying atmosphere, oceans and ice sheets, and for his unique and outstanding human qualities.

Highlights

• Melt area in 2015 exceeded more than half of the ice sheet on July 4th for the first time since the exceptional melt events of July 2012, and was above the 1981-2010 average on 54.3% of days (50 of 92 days).
• The length of the melt season was as much as 30-40 days longer than average in the western, northwestern and northeastern regions, but close to and below average elsewhere on the ice sheet.
• Average summer albedo in 2015 was below the 2000-2009 average over the northwest and above the average over the southwest portion of the Greenland ice sheet. In July, albedo averaged over the entire ice sheet was lower than in 2013 and 2014, but higher than the lowest value on record observed in 2012.
• Ice mass loss of 186 Gt over the entire ice sheet between April 2014 and April 2015 was 22% below the average mass loss of 238 Gt for the 2002- 2015 period, but was 6.4 times higher than the 29 Gt loss of the preceding 2013-2014 season.
• The net area loss from marine-terminating glaciers during 2014-2015 was 16.5 km2. This was the lowest annual net area loss of the period of observations (1999-2015) and 7.7 times lower than the annual average area change trend of -127 km2.

Yes, Greenland is melting.

Antarctic Peninsula in 'dramatic' ice loss
By Jonathan AmosBBC Science Correspondent

Satellites have seen a sudden dramatic change in the behaviour of glaciers on the Antarctica Peninsula, according to a Bristol University-led study.

The ice streams were broadly stable up until 2009, since when they have been losing on the order of 56 billion tonnes of ice a year to the ocean.

Warm waters from the deep sea may be driving the changes, the UK-based team says.

The details of the satellite research are published in Science Magazine.

They include more than 10 years of space observations of a broad swathe of coastline roughly 750km in length, on the south-western sector of the peninsula.

Here there is a multitude of glaciers slipping down mountainous terrain and terminating in the Bellingshausen Sea.

"Around 2009/2010, the surface in this part of the southern Antarctic Peninsula started to lower at a really quite dramatic rate, of 4m per year in some places. That's a pretty big signal," said Bristol's Prof Jonathan Bamber.

"The total loss of ice per year is about 60 cubic km. Just to put that into some kind of context: 4 cubic km is roughly equivalent to the domestic water supply of the UK every year."

Greenland melt

The Antarctic is losing the equivelent of 15 times the entire domestic water supply of the UK a year. That is significant.

My God, how I envy your erudite answers.

Do you know what an answer is?
I was just having fun with your fear mongering

Very close to the record melt year of 2012.

When folks talk about "melt" -- like in your cited paper below -- you are EXAGGERATING greatly what the true meaning of that is. It is not even necessarily a permanent loss of ice. There are "days" of melt where the ice is RESTORED during the nights or the following days.

If you like SCARING folks into believing that 40% of Greenland is "melting" into the sea -- carry on. But it is fear-mongering to do so..

 

[flacaltenn]

Likely more ACTUAL ice lost to actual sublimation on those VERY LONG summer days --- than lost because of this definition of "melt".

 

[Old Rocks]

Yes, I know what the answer is. That is a figment of LaDumbkopf's imagination. Ice caps, like glaciers, grow when the amount of new snow exceeds the amount of melt. In almost every place that glaciers exist, and in both places where we have ice caps, the melt is exceeding the amount of new snow.

 

[Old Rocks]

Sublimation or melt, the result is the same. The water ends up in the ocean. How do you 'greatly exaggerate' the measured amount of ice that is leaving Greenland every year? And how do you exaggerate the increase in that amount. And the measured increase in the rate of glacial flow into the ocean that we are seeing both in Greenland and Antarctica.

Mr. Flacaltenn, you are playing with words, trying to destroy their meaning.

The sky is falling....The Sky is falling,,,

The paper NEVER addresses what is natural variation... SO it is crap conjecture.

It is amazing how easily duped warmers are.

The WANT to believe AGW is real...so they believe. It fits their dogma PERFECTLY, so it must be true.

how does the ice from the process of sublimation make it to the ocean? me thinks you are cuckoo. Explain to the class how sublimation process the ice would get to the ocean.

Don't ask questions. You need to just BELIEVE!

he won't answer and I know it. I need an education as to how solids turned to vapor returning to solids makes it to the ocean. That's a new one.

How did the tress grow under that ice in Greenland?

very carefully

 

[CrusaderFrank]

So is the imaginary "ice loss" caused by the 2 Decade pause in temperature or is there some other factor: aldebo, magentic field fluctuations, cow farts, etc

 

[LaDexter]

Ice caps, like glaciers, grow when the amount of new snow exceeds the amount of melt.

WRONG.

The accumulation of the annual ice core minus what breaks off in the form of icebergs - that is the equation of what an ice age glacier adds every year. Greenland isn't "melting" at all, and neither is Antarctica. NASA documents Antarctica has added at least 80 billion tons of ice every year since Algore started lying about CO2, which is why the fudgebakers talk about the Antarctica PENINSULA, which is tectonically active.

Greenland isn't melting either. It is manufacturing a new ice core every year.
