Antarctic's glacial melt - volcanoes, or global warming?

[zolace]

The Antarctic serves as an illustration just hard it is to accurately determine what damage, if any, is caused by the slight rise in temperatures that has occurred over the past century or so - as well as what might be causing the slight rise.

And how easy it is, given politics, to jump on the bandwagon of 'global warming'.

A new study by researchers at the University of Texas, Austin found that the West Antarctic Ice Sheet is collapsing due to geothermal heat, not man-made global warming.

Researchers from the UTA’s Institute for Geophysics found that the Thwaites Glacier in western Antarctica is being eroded by the ocean as well as geothermal heat from magma and subaerial volcanoes. Thwaites is considered a key glacier for understanding future sea level rise.

UTA researchers used radar techniques to map water flows under ice sheets and estimate the rate of ice melt in the glacier. As it turns out, geothermal heat from magma and volcanoes under the glacier is much hotter and covers a much wider area than was previously thought.

Thwaites glacier is one of a number of massive west Antarctic glaciers...all of which have been found to more unstable than the past, including the ones without changing geothermal influences.

This is exactly why generalizations, and simplified alarmist hysteria about "global warming" must be viewed with skepticism.  A line of volcanoes under glaciers could just as easily have ocean currents that moved the generated warmer water away from the glaciers as toward them.  Yes, there are volcanoes down there; yes, they generate immense amounts of heat, but what exactly is their effect?

Forwarding this to my "little" thread...

Geothermal heat... all of a sudden? Geologic processes take tens of thousands, if not millions of years to set in. And here we have geothermal heat in 5 decades.  And as far as I know, there are only two or three active volcanoes in Antarctica (such as Mount Erebus and Mount Christos), and they are located far away from the most actively receding glaciers.

[Benjig]

Some say the global warming dont exist, those are natural cycles of the earth, just like we once had the ice age, once we reach one point we going backwards.

[Lethn]

I've said it a million fucking times and I'll say it again, we know absolutely nothing about this planet and how the universe work and this article proves it.

Magma can rise quite suddenly and recede just as quickly. There are way too many variables that the alarmists simply choose to ignore. It makes a good scare headline for sure, but not good science.

The earth's orbit is changing.  We have been in an oval orbit around the sun.  20 or 30 years ago, the earth began changing its orbit to a round one.
That means the earth is closer to the sun during winter months.  The earth is still tilted, but the affect is to more or less even out the temperatures.  Here in Maine, we have long winters.  There were snow storms in June.  We used to have an unbearable August.  Now August is not quite so hot and humid.  Even though winter seems to last longer, the temperatures don't dip down and stay there for weeks.  We still have negative numbers, but for only 3 or 4 days, then the temps rise.  What is happening is a moderation of temps all year long.

I'm not sure how other parts of the globe are affected.  The article did say the equator is moving north.  So the hottest part of the earth is now some degrees north of where is usually is.  Maybe that's why the southwest is so much hotter now.  Even the north and south poles will be effected.  They are also closer to the sun year round.

Of course no piece of information is an island on to itself.  Thus the problem of global warming advocates, particularly the political ones.

Glad to see you do at least acknowledge this.

Those volcanoes are going to melt some ice and put more fresh water into the oceans. This might undermine the thermo haline circulation system and we will have cooling any way. In any case it has nothing to do with people or CO2 and it can’t be stopped any way.

If a Global Climate Model cannot back-cast, it's useless.

Here's one that performs well...

There is evidence that geothermal events such as magma movement is related to solar events, at least partially. The sun has been changing recently in its own cycle, and the earth has a different position on the opposite side of the solar plain. The magnetosphere of earth which allows us to have an atmosphere is generated by the movement of the molten magma around a large iron core, making earth basically a huge electrical dynamo. As solar flares hit earth, it interacts with the magnetosphere potentially changing the path of magma flow, possibly resulting in earthquakes and other fun geothermal activity alterations. It could very well be that it is caused by volcanoes, AND global warming (just not man made).

This is possibly big.  I trust Joannenova, by the way.

But the article by, IIRC, David Evans, must be studied in some depth.  Regardless, he is posting his spreadsheet for critical examination.

What a load of crap.  You even nearly pointed out the stupidity of your claims.  It is winter here while it is summer there.  Climate is not connected to what you claim.

This was in the Smithsonian Institute magazine.  I believe they might be a tad smarter than you are.  What do you think causes seasons?  Mankind?  Our seasons are dependent on the sun.  We are not the center of the universe any more.  That was eons ago when people were killed for believing the earth was not flat.  They were killed for believing the sun did not rotate around the earth.  Our seasons come because of our relationship to the sun.  When we are closer, we are warmer.  When we are farther away, we are cold.  When it is night, we do not see the sun.  Get with it...!!!!!!!! 

[umair127]

Seasons are caused by changes in the orientation of the earth relative to the sun and when it is summer in the northern hemisphere it is winter down south.

I wasn't rubbishing the Smithsonian just the interpretation you have gleaned (either directly or via some other moron) from it.

Thanks to all the publicity and funding devoted to global warming climate change research, scientists and eco-tourists have flocked to Antarctica.

Unfortunately, all of the human traffic associated with researchers and eco-tourists is killing Antarctica!

    Scientists warn of tourism threat to Antarctica

    Tourist numbers have exploded from less than 5,000 in 1990 to about 40,000 a year, according to industry figures, and most people go to the fragmented ice-free areas that make up less than one percent of Antarctica.

    A growing number of research facilities are also being built, along with associated infrastructure such as fuel depots and runways, in the tiny ice-free zones.

    It is these areas which contain most of the continent’s wildlife and plants, yet they are among the planet’s least-protected, said a study led by the Australian government-funded National Environmental Research Programme (NERP) and the Australian Antarctic Division.

Who did the scientists warn? Themselves?

Sometimes, to study an environment, you have to kill it.
