So, depending upon which side you want to take, there is an article for you!!

The only reason the terminology
"Global Warming" took off is because of specific weather phenomena located on our part of the globe. However there are drastic changes happening throughout our planet and it is a direct result of mankind's influence and failed custodialship of our Earth.
That Glacier advance is not unique to just South America. I have friends and family in
Cape Town , South Africa and they say the winter weather lasts longer now and snow is more common than ever before in some higher mountain elevations. The same is true for friends and family I have in
Perth, Brisbane, and Sidney , Australia where winters are not only longer but also colder. Many times they have had later freak winter snows in Sidney that is something uncommon from the past.
As you pointed, considering where you are there could be a differing point of view. But it is also noteworthy to see that the equatorial areas of the Earth are experiencing some of the most servere and distructive weather phenomena than ever before. The terminology should be more appropriately changed to
"Global Ruin". If mankind as a whole, not just big companies as targeted by many environmental movements, but the entire human race has to get on board and change their personal habits or things will continue to spiral down hill. Unfortunately looking at past experience with humankind tells us they won't unless forced to.
Another another interesting note, this
"Global Warming" in the
Northern Hemisphere has had some interesting side effects in exposing what use to be extensive and massive temperate forests in the Arctic Regions. Here's a mention of it in one of my blogs on ancient forests of the north. What is interesting is that the melting of the glacial ice and the exposed ground permafrost has uncovered numerous tree stumps and logs in an area otherwise inhospitable environment to anything but moss and lichens. One of the main researcher's has been
Hope Jahren who studies ancient climates and in this case what has been named the
Oacene World Climate. The beatiful thing about the stumps and logs is that they are still real viable wood for study. In fact the wood still burns unlike fossilized wood you would find in areas like Arizona's Petrified Forest Presevre. Hence they are able to do real isotope studies of the woody celluose tissues left over. They area of discovery is Axel Heiberg Island which is one of the northern most islands beloging to the Canadian Achealopelago next to northern Greenland. This area is exactly 1,110 kilometers north of the Arctic Circle which itself is just north of Hudson Bay.

Here's another interesting link of the stumps found where they grew. What they discovered is that the distruction was instantaneous and caused by massive flood waters all at once. The flood waters overwhelmed the trees, some of which have been found to be over
three meters (little over ten feet) in diameter. The trunks were snapped off like those snapped at
Mount St Helens during that pyroclastic flow which flattened everything in it's pathway. In this case the logs snapped off the trunks and were quickly buried in sediment. Many of these have been uncovered and have yielded information that the trees were as high as 80' to 120'. In the link below, take note of the valley with the tree stumps and the hills surrounding the lower plain. Notice the horizontal lines on all the hills. If you've ever been to a resevoir that has drought conditions and lowering water levels over a long period of time, then you've also seen the same horizonatal lines which were created by the wind blown water against the shoreline. Apparently this is the result of lowering flood waters from this area as well when the waters started to recede.

Below is yet another interesting link by a Canadian researcher who has more photos of branches, leaves, twigs, and cones from the most dominant species of tree at that time, the
Dawn Redwood (Metasequoia) which was at one time thought to be extinct but discivered in 1944 in China. They also found an area off
Axel Heiberg a much smaller island called
Ellesmere Island for which an actual beaver pond was discovered with cobble stones, logs and sticks with the distinctive beaver cuts. Animal fossils from these areas also revealed not only beaver, but also crocodile, bear, wolverine, badger, rabit and small deer and mostly northernly record of a horse.

What fasinates me is the structure of water itself during this time period.
Hope Jahren's isotope studies revealed the wood celluose contained only
Oxygen 16 and none of the
Oxygen 16 and Oxygen 18 found in modern tree tissues. The puzzling part is that rain water originating over oceans contain
Oxygen 18. But the presence of only
Oxygen 16 suggests that the trees and surrounding flora did'nt get their water source from off the oceans but rather water from lakes, rivers and springs. Water that is influenced by the earth with it's
oxygenation and energizing qualities, similiar to the water
Viktor Schauberger found in springs from Pristine old growth forests in the 1920s and 1930s
Austria.
The atmosphere was found to be different as well. It's average humidity was around 60% - 67%. The area of both Polar regions today is mostly like a cold desert as far as humidity. Very dry climate. It was found that the area never had snowfall or even a frost. It was a mild temperate region like Vancouver, Canada. The existance of Palm tress was also interesting. The humidity levels were said to reach as high as the middle trophosphere and higher, possibly to the stratosphere. This kept winter dormancy temperatures mild and also even frost free let alone and snow or even glaciers.
The other interesting thing is that the same conditions for forest plants and animal existance existed at the
Antarctica at the same time as well. Tree trunks and logs have been found from certain receeding glaciers as well as islands off the coast. Most of these in the Southern regions were a deciduous type of tree.
The present global warming trend is not a natural phenomena, it is most certainly and strictly caused by mankind in general.
