Studies in Antarctica? They can prove it!

I thank my friend and partner on this blog Stephanie Caracciolo of this idea for my article.

Today, we celebrate the Antarctica Day, the commemoration of the day when you signed the Antarctic Treaty (1 December 1959) which established that Antarctica was a continent of study and peace.
Now, Stephanie was in Antarctica, according to some studies at the Uruguayan "Artigas".
So, she knows certain things, like I know something about, being graduated as a technical chemical-biological laboratory and specialized as a technical quality control, safety and environment, although currently out of work.
Thanks to my studies, I know that the Earth's climate can change course.
The history of the Earth has always been characterized by periods of heat and cold periods.
I am reminded of the fourteenth century, when there was a colder period that produced poor harvests and famine, a plague has reaped many victims.
About a third of Europe's population died.
This was documented by chroniclers such as Italian (precisely, Siena) Agnolo di Tura and English Thomas Walsingham (died 1422).
In these cases, there were no exhaust gases of human activities, which are seen as the only cause of climate change.
Yet, the climate naturally changed and everything is imprinted in the "memory" of the Arctic and Antarctic ice.
In these ice cores they have been made and "carrots" see themselves layers of ice dating back to various eras.
Based on the differences of the various layers of ice you notice the climate change that we have been throughout history.
One thing must be clear: human activities pollute and you must make sure that they cause the least damage possible to the environment. However, it would not be reviewing the theory of the weight of human activities on global warming?
