The amount of ice at the Antarctic

is INCREASING not going down, says NASA
 

 

 

A NEW NASA study of the Antarctic from space

has thrown the case for climate change into disarray

after finding that more NEW new ice

has formed at the Antarctic

than has been lost to its thinning glaciers.
 

 


The US space agency research (NASA) claims an increase in Antarctic snow accumulation that began 10,000 years ago is,

"currently adding enough ice to the continent to outweigh the increased losses from melting glaciers."

Global warming theories have been thrown into doubt after NASA also claimed current horror predictions into future sea-level rises may not be as severe.

Major studies previously made the case for global warming being a man-made problem, including the the Intergovernmental Panel on Climate Change's (IPCC) 2013 report, which said that Antarctica was overall losing land ice.

But a NASA spokesman said:

"According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001.

"That net gain slowed to 82 billion tons of ice per year between 2003 and 2008."

NASA agrees ice has been lost in the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica.

But says the gains elsewhere, which total 200billion tonnes a year, outweigh all these losses of 65billion tonnes a year - leaving a net annual Antarctic ice gain of 135 billion tonnes.



Jay Zwally, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published in the Journal of Glaciology, said:

"Our main disagreement is for East Antarctica and the interior of West Antarctica - there, we see an ice gain that exceeds the losses in the other areas."

Mr Zwally added his team,

"measured small height changes over large areas, as well as the large changes observed over smaller areas."

Scientists calculate how much the ice sheet is growing or shrinking from the changes in surface height that are measured by the satellite altimeters.

In locations where the amount of new snowfall accumulating on an ice sheet is not equal to the ice flow downward and outward to the ocean, the surface height changes and the ice-sheet mass grows or shrinks.

 

Antarctic ice gain reduces sea levels

by 0.23mm a year, says NASA
 


The study analyzed changes in the surface height of the Antarctic ice sheet measured,

  • by radar altimeters on two European Space Agency European Remote Sensing (ERS) satellites, spanning from 1992 to 2001

  • by the laser altimeter on NASA's Ice, Cloud, and land Elevation Satellite (ICESat) from 2003 to 2008

It had been argued by the climate change lobby the gains in elevation seen in East Antarctica were due to recent increases in snow accumulation.

 

But the NASA team used meteorological data beginning in 1979 to show the snowfall in East Antarctica actually decreased by 11 billion tons per year during both the ERS and ICESat periods.

They also used information on snow accumulation for tens of thousands of years, derived by other scientists from ice cores, to conclude that East Antarctica has been thickening for a very long time.

The spokesman added:

"Extra snowfall that began 10,000 years ago has been slowly accumulating on the ice sheet and compacting into solid ice over millennia, thickening the ice in East Antarctica and the interior of West Antarctica by an average of 0.7 inches (1.7 centimeters) per year.

"This small thickening, sustained over thousands of years and spread over the vast expanse of these sectors of Antarctica, corresponds to a very large gain of ice - enough to outweigh the losses from fast-flowing glaciers in other parts of the continent and reduce global sea level rise."

Mr Zwally said:

"At the end of the last Ice Age, the air became warmer and carried more moisture across the continent, doubling the amount of snow dropped on the ice sheet.

"The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away."

Mr Zwally, however, did warn there is no room for complacency.

He said it might only take a few decades for Antarctica's growth to reverse.

He said:

"If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they've been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years.

"I don't think there will be enough snowfall increase to offset these losses."

And Ben Smith, a glaciologist with the University of Washington in Seattle not involved in the research, said:

"The new study highlights the difficulties of measuring the small changes in ice height happening in East Antarctica.

 

"Doing altimetry accurately for very large areas is extraordinarily difficult, and there are measurements of snow accumulation that need to be done independently to understand what's happening in these places."

 









 

 





 

 Global Cooling

-   Decade Long Ice Age Predicted as Sun 'Hibernates'   -

The big freeze could last a decade

as sun goes to sleep
 

 

 

SCIENTISTS claim we are in

for a decade-long freeze as the sun

slows down solar activity

by up to 60 per cent.
 

 


A team of European researchers have unveiled a scientific model showing that the Earth is likely to experience a "mini ice age" from 2030 to 2040 as a result of decreased solar activity.

Their findings will infuriate environmental campaigners who argue by 2030 we could be facing increased sea levels and flooding due to glacial melt at the poles.

However, at the National Astronomy Meeting in Wales, Northumbria University professor Valentina Zharkova said fluctuations an 11-year cycle of solar activity the sun goes through would be responsible for a freeze, the like of which has not been experienced since the 1600s.

From 1645 to 1715 global temperatures dropped due to low solar activity so much that the planet experienced a 70-year ice age known as Maunder Minimum which saw the River Thames in London completely frozen.
 


 




 




 

The researchers have now developed a "double dynamo "model that can better predict when the next freeze will be.

Based on current cycles, they predict solar activity dwindling for ten years from 2030.

Professor Zharkova said two magnetic waves will cancel each other out in about 2030, leading to a drop in sun spots and solar flares of about 60 per cent.

Sunspots are dark concentrations of magnetic field flux on the surface that reduce surface temperature in that area, while solar flares are burst of radiation and solar energy that fire out across the solar system, but the Earth's atmosphere protects us from the otherwise devastating effects.

She said:

"In cycle 26, the two waves exactly mirror each other, peaking at the same time but in opposite hemispheres of the Sun.

"We predict that this will lead to the properties of a ‘Maunder minimum.
 

 


The theory is likely to infuriate environmentalists

who fear the globe is heating up

 

"Over the cycle, the waves fluctuate between the Sun's northern and southern hemispheres. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97 per cent."

Research colleagues Simon Shepherd of Bradford University, Helen Popova of Lomonosov Moscow State University and Sergei Zarkhov of the University of Hull used magnetic field observations from 1976 to 2008 at the Wilcox Solar Observatory at Stanford University.

A Royal Astronomical Society spokesman said:

"It is 172 years since a scientist first spotted that the Sun's activity varies over a cycle lasting around 10 to 12 years.

 


Could you handle ten years of winter?
 

"But every cycle is a little different and none of the models of causes to date have fully explained fluctuations."

The "double dynamo" theory appears to support claims of researchers who argue Earth will soon experience major global cooling due to lower solar activity as the sun goes into a sustained period of hibernation.

Environmentalists meanwhile claim global temperatures will increase over the period unless we drastically reduce carbon emissions.








 
 


 Global Warming 'is FAKE'

-   Volume of Ice Caps is INCREASING, Claims Top Geologist   -

A geologist has made claims

that goes against the typical global warming thinking
 

 

 

THE WORLD is not heating up,

some areas are actually getting colder

and the volume of polar ice caps

is INCREASING in some places,

a leading geologist has claimed.
 

 


James Kamis suggests "conflicting temperature trends" between oceans and the Earth's atmosphere could dispel the "myth" of man-made global warming.

Put simply, he says our atmospheric temperature has remained static for more than 18 years, the Atlantic has got colder, and it is only the Pacific Ocean where things have heated up.

Mr Kamis said:

"Scientists from the National Oceanic and Atmospheric Administration (NOAA), the National Aeronautics and Space Administration (NASA), and many universities are at a loss to explain recent conflicting temperature trends from Earth's oceans and atmosphere."

claims the ice caps increased
 

"It can be boiled down to this: temperatures of the Earth's three big fluid systems are each trending in different directions:

  • the temperature of the Pacific Ocean is rising

  • the temperature of the atmosphere has remained constant

  • the temperature of the Atlantic Ocean is cooling"

He said the temperature variances do not fit previous climate model predictions.

He added:

"Climate scientists favoring the theory of man-made global warming are flooding the media with new, and this time supposedly very reliable, explanations that are generated from their latest super-computer climate models."


 

 



Opposing scientists claim global warming has melted the Greenland ice cap at an alarming rate to the point that freshly melted ice flowing into the Atlantic is lowering the seawater temperature there.

However, Mr Kamis said that with no significant atmospheric temperature change in 18.7 years, global warming is not likely to be the cause of the melting.

Mr Kamis is a former employee of BTA Oil Producers, based in Midland, Texas, a private firm which has been active in oil and natural gas exploration, development and production for 50 years.

 

He has also been a long-standing member of the American Association of Petroleum Geologists, so his impartiality on the subject of whether man's use of fossil fuels has led to global warming is open to question.

But he claims the facts speak for themselves.

He added:

"The entire Atlantic Ocean is cooling, and not just in the northern portion of the Atlantic that is adjacent to Greenland.
 

 

It is not in dispute that

the North Atlantic waters are getting colder
 

 

"This strongly suggests that outflow of summertime Greenland ice cap melt water into the northern portion of the Atlantic Ocean is not the primary driving force behind cooling the entire Atlantic Ocean.

 

"Recent research from NASA's Operation Ice Bridge clearly shows that Greenland's ice mass loss is only occurring in areas immediately adjacent to the ocean.

"This perimeter-based ice loss is greatest in areas where the ice cap overlays known deep geological fault zones that are emitting geothermal heat onto the base of the ice cap.

"The interior portions of the Greenland Ice Cap are in ice mass balance. The extent of Arctic Ocean sea ice has increased the last three years, and not decreased as predicted.

"The Antarctic Ice Cap extent has increased steadily for thirty five years, and not decreased as predicted."
But the Pacific Ocean

is getting warmer
 


He believes melting of the Greenland Ice cap to be caused by heat from ancient volcanic eruptions and geothermal heat flow from below the surface.

He told Climate Change Dispatch:

"Many noted and well-intentioned climate scientists and universities are now starting to publicly admit that overwhelming amounts of new research indicates that the theory of man-made global warming does not properly explain many observed climate trends.

 

Reason dictates that a more balanced approach to studying climate trends is needed."


 




But other experts disagreed.

 

Michael Mann, a climate scientist of Pennsylvania State University, said:

"We may see warming even faster than what the models are predicting."

And Michael England, a professor at the University of New South Wales in Australia, said global temperature has steadily climbed by 1.4 F since 1880.

He said:

"Global temperatures may rise another 4 to 7 F (2 to 4 C) by 2100."
