Climate Change itself isn't caused by humans, but the rate of change is.
Were there no human induced warming, climate change at this time should be going in the opposite direction from what is observed based on what we know of the long tern natural factors impacting on global climate. More accurate to say causes of climate change consist of many components, some of which are related to the impact of GHG emitted by humans. At the current time, the aggregate strength of components other than human induced GHG is being overwhelmed by human induced GHG. This does not mean in the future, certain other elements can not gain in strength until the aggregate non-man made effects surpass those of man-made effect. But for now, Human GHG emission is controlling the direction og global climate change.
