Wow just a few months ago it was at a record high amount of ice, now it is at a record low???....

Almost sounds like fake news.

How they ascertain those record levels exactly is a mystery science all its own.



Nah, we've had satellites figured out for awhile now.

The "records" they refer to indicate that they're the records "since we began tracking" sea ice in 1979. We have no way of measuring before that, as when sea ice melts, it becomes, well, sea water.

A big chunk must have fell off recently so they can update their data to favor their propaganda.


Or...it fluctuates, like the article mentions, and which is true. Nobody is trying to fool anyone here guys, nor is any of this "fake news." They're actual measurements, and nobody is hitting the panic button saying it's always shrinking and will continue to do so. We could just as easily be back to record sea ice in another two years.

I'd rather we gain an understanding of these fluctuations than get all defensive when sea ice is shrinking and celebrate when it's growing. Science is for grown-ups, let's leave the political nonsense to the feeble-minded. Everyone in this thread so far is too smart for that.

I'll repeat: this isn't, nor is it claimed to be, indicative of an ongoing trend. In fact, it very specifically states that its cyclical, and that the record-keeping / observations have only been ongoing for less than 40 years.

Records were made to be broken.
Havent we only been keeping records since 1979 or about then?
Not long enough...


Scott and Shackleton logbooks prove Antarctic sea ice is not shrinking 100 years after expeditions

Antarctic sea ice had barely changed from where it was 100 years ago, scientists have discovered, after poring over the logbooks of great polar explorers such as Robert Falcon Scott and Ernest Shackleton.

Experts were concerned that ice at the South Pole had declined significantly since the 1950s, which they feared was driven by man-made climate change.

But new analysis suggests that conditions are now virtually identical to when the Terra Nova and Endurance sailed to the continent in the early 1900s, indicating that declines are part of a natural cycle and not the result of global warming.

Well okay but those 'satellites' record a steady slow melting since they were put up, reflecting an average rate of rise, amounting to about 2 inches since they been monitoring from 1990. Heres a chart...

Nasa
No "records" there...

Looks like you might need more info.


NASA

Data from NASA's GRACE satellites show that the land ice sheets in both Antarctica and Greenland are losing mass. The continent of Antarctica has been losing about 118 gigatonnes of ice per year since 2002, while the Greenland ice sheet has been losing an estimated 281 gigatonnes per year.



Sceptical Science

Antarctica is a continent with 98% of the land covered by ice, and is surrounded by ocean that has much of its surface covered by seasonal sea ice. Reporting on Antarctic ice often fails to recognise the fundamental difference between sea ice and land ice. Antarctic land ice is the ice which has accumulated over thousands of years on the Antarctica landmass through snowfall. This land ice therefore is actually stored ocean water that once evaporated and then fell as precipitation on the land. Antarctic sea ice is entirely different as it is ice which forms in salt water during the winter and almost entirely melts again in the summer.

Importantly, when land ice melts and flows into the oceans global sea levels rise on average; when sea ice melts sea levels do not change measurably but other parts of the climate system are affected, like increased absorbtion of solar energy by the darker oceans.

To summarize the situation with Antarctic ice trends:

Antarctic land ice is decreasing at an accelerating rate
Antarctic sea ice is increasing despite the warming Southern Ocean




2014, NASA. Antarctic Sea Ice Reaches New Record Maximum

Editor’s note: Antarctica and the Arctic are two very different environments: the former is a continent surrounded by ocean, the latter is ocean enclosed by land. As a result, sea ice behaves very differently in the two regions. While the Antarctic sea ice yearly wintertime maximum extent hit record highs from 2012 to 2014 before returning to average levels in 2015, both the Arctic wintertime maximum and its summer minimum extent have been in a sharp decline for the past decades. Studies show that globally, the decreases in Arctic sea ice far exceed the increases in Antarctic sea ice.

The land ice undoubtedly has a reason for losing mass...

the Sea Ice is behaving normally, growing then breaking off into the waters


What is the new factor which is decreasing the volume of ice on both the Antarctic and Greenland mass...


my guess is below the ice cap volcanos and or hotspots due to hot Mantle plumes heating the crust on which the ice sheet sits.... I had already speculated that there might exist huge domes or ice caves hidden down at the surface, lakes even rivers eroding the ice sheet envelope covering both Antarctica and perhaps even the Greenland Glaciers


 



i'll bet the attention grabbing, extremely long "Crack" in the ice-sheet at Antarctica is a result of the same 'new' factor of recently increased geo-thermal activity hidden from view below the surface ice sheets sitting on the land

all I can think of is 'heat'...


unless the 5 dimensional planet Nibiru is also one of the causes


care to put forth a reason or cause(s).... thanks in advance

Everything is connected and works together. Think systems. And well beyond narrow horizons. [Note that the following does not preclude the effects of human industry.]

Ancient Interstellar Collision: May Help Explain Climate Change




TO CLARIFY: The universe is a really big place, incredibly hUUUge when you think about it, absolutely magnificent really, and there's lots of stuff going on it. Too much to think about. Which is why we don't need science. It's a waste of time. And money. Money better spent on pussy and baby monkeys.

There is alot at play which factors into this equation and the Pacific Ocean is as good a place to start as any other...
You see the Pacific Ocean is heating up at an alarming rate... Because of this we see warm weather trends referred to as El Nino effect which is a climate cycle in the Pacific Ocean which has a global impact on weather patterns and has a suspected duration of 7 years... Or so they say...

Greenhouse gases are the suspected culprit as heat is trapped and absorbed by the Ocean... But I feel the ring of fire is also partially to blame with increased volcanic and seismic activity...

The real problem is that when one aspect of the Earth ecosystem is affected it results im a chain reaction... This simple cause and effect... It really is a fine line to maintain the balance which produces conditions suitable for not only comfort but life itself...
So the green house effect heats the oceans then creates warm weather systems with a global effect which then melts polar ice and also perma frost... Now that the polar ice and perma frost melts it introduces a new player to the stage which is methane which has long been trapped by these...

Now the released methane with a huge carbon footprint drastically increases greenhouse gases which warms the oceans which produces warmer weather which melts more Ice which releases more methane... I think you get the picture... It is feeding on itself and growing in intensity and severity...

Soon there will be another name for an even warmer weather system because its what will need to be done to reassure everyone that everything is ok...

Well thats pretty far from the truth as you can see we are experiencing weather patterns spiraling out of control... Record temperatures, floods, droughts, tornadoes, hurricanes...

The Earth is alive and it is struggling to right itself after awakening from a peaceful slumber and realizing it is sick... It has its own built in safeties... It does not want to die which is what would happen if heating went unchecked and even the atmosphere was eventually cooked off...

But this will most likely not happen thanks to all the Ice... So Earth will not continue to heat up forever... Don't get me wrong though this is still very bad because as the temperatures continue to increase and the cycles continue to feed off each continue to worsen all that ice will melt and storms will get so bad that exactly the opposite of what you may think will occour... Heating up will no longer be the problem instead we will have storm cells raging out of control that do not stop until the Earth has a new Ice age... This will not be gradual once it gets to a certain point the heating will turn into a runaway and then snap the Earth will freeze rapidly...

But you dont have to worry about being cold because most life won't make it to that stage without special conditions for survival...

Naah.The Antarctic land ice is not shrinking,the Earth is expanding,duh!

The earth is not expanding sorry to say...

But the Earth is growing due to a constant delivery of materials from space which amount to approximately 100 tons worth per day...

I'm confused. Growing but not expanding?

I realize that is confusing but I said it because the Earth is not spreading out or inflating like a balloon from within nor of its own doing...

Instead the growth the Earth experiences is from an external source...
