Go to the website and go halfway down the page and you will the following:
Recent Climate Change: How has the climate changed in the last 100-150 years? What has caused the changes?
Future Climate Change: How might climate change over the next 100 years and why?
State of Knowledge: What aspects of climate change do we understand best? What are the most significant uncertainties?
Past Climate Change: What has caused the Earth's climate to change throughout its history? How has it changed?
This section of the web site talks about the forces that have caused earth's climate to change. Before 1780, humans had no effect on this process. The causes of climate change were natural, and included variability in the sun's intensity, the earth's orbit, and volcanic activity. These in turn fed into feedback loops that accelerated the changes. These feedback loops involved greenhouse gases and ocean circulation. Earth's climate has experienced many cycles of global cooling and warming. The warm periods tend to be more stable than the cold ones, and the climate change change abruptly from cool to warm and vice versa.
