Carbon Blueprints - Manmade Global Warming vs. Nature

WHAT IS THE DIFFERENCE BETWEEN NATURAL CLIMATE CHANGE AND GLOBAL WARMING?:
As we find from our research on this subject, the question is not, has the earth warmed up in the past hundred years, for it has. (Research shows that the earth has also cooled since 1998 until the current year minus 2006 which was a record year) Instead the question is, did this all occur as a natural cycle that occurs through the years or is this from the effects of humans and industrialization?

Some may say this is because of industrialization because we have only begun to research and record the changes in the climate with great accuracy within the last 40 years. When the industrial revoloution began and fossil fuels were discovered and began to be burned, the research over climate change was not a well studied topic and accurate temperature readings were not taken due to lack of need, technology, etc. But with what records they have been able to acquire a trend has been found to show an increase in temperature,(until 1998 when it began to decrease) though is this due to human advancement or nature?

Because of history we know that there have been times of Natural Climate Change, both colder and hotter spells. The Romans Empire went through a hot spell around 600BC to 200 AD where the Saraha Desert and almost all of North Africa was wet and fertile and became dry and desolate. There was also a Medieval Warming from 900 - 1300 AD when Eric the Red Colonized Greenland. There was also a cold spell from 1300-1850 AD that killed off these colonies, farms, and many of it's people. These cannot be proven beyond a shade of a doubt because these happened so long ago but archeologists and known history claims these environmental changes to be certain.

It has happened in the past but does that mean it is happening now? No, not for certain. The limited history and knowledge of what is happening on the earth can only be speculated on. Could it be that the human effect is amplifying the problem, again this is hard to know, if it is amplifying it, we would need to have a base knowledge of the change that would occur, which is impossible to establish since the earth holds so many secrets. This base knowledge comes from a world wide base level of emissions that were on the earth before the Industrial Revolution, which is an unknown. We would need to know this level of emissions to find out how much humans have added to earth's total carbon emissions. Yet we only started recording emissions after the Industrial Revolution already began. Ice cores and other research are only so accurate. Can we rule it out, though? NO.
