The graph below shows the concentration of CO2 (blue line) and the global temperature behavior (red line). There is a strong relationship between these two factors.

Please, pay attention to the red line behavior.

Until the 20th century what we see are only oscillations. I named this behavior of "climate change". After a period of rapid industrialization the red line presents an exponential behavior.


In summary, before industrial era the human influence on the climate was negligible. After we start to use the oil as a primary energy source, the anthropic activity becomes clear. Therefore, in my view, what we experience now is the "global warming". Before that, there were "natural" climate changes, although the global warming is a climate change too, it's a result of our economic growth pattern. So the term "climate change" should be used for "natural" climate changes!
