Last quote by Will Steffen

Over the past 7,000 years the primary forces driving change have been astronomical - changes in solar intensity and subtle changes in orbital parameters, along with a few volcanoes. Human-caused greenhouse gas emissions over the past 45 years have increased the rate of temperature rise to 1.7 degrees Celsius per century, dwarfing the natural background rate. We are not saying the astronomical forces of our solar system or geological processes have disappeared, but in terms of their impact in such a short period of time they are now negligible compared with our own influence.
