What do you mean by human-driven climate change?

When scientists and environmentalists talk about climate change, they are usually referring to ‘human (or man)-made climate change’, which is different to regular old ‘climate change’.  Climate change has always occurred throughout history, which is clearly seen in the geological record; this is a ‘natural’ process and one humankind cannot affect.

However, it is the rapid rate and the magnitude of climate change occurring now that is of great concern. The degree of change to the natural cycle of climate change is attributed to human activities – man-made climate change – which cause large amounts of CO2 to be emitted into the atmosphere.
