• The information's collected from the Paleoclimatic studies have produced (separately) two sets of graphs. One of which represents the levels of carbon dioxide in the atmosphere and another atmospheric temperatures. The age of the samples taken can be measured accurately using isotopic dating
• These graphs clearly indicate the relationship between the level of carbon dioxide (CO2) in the atmosphere and global temperatures are closely correlated
• This is yet again strong evidence that observed climate change is mainly caused by human activity through the addition of greenhouse gases (mostly CO2) into the atmosphere
• CO2 is not the only greenhouse gas (it neither has the strongest warming potential) but considering that it is largely predominant in the atmosphere comparatively with other greenhouse gases it is presently the most to blame for global warming.
