Pro to the question "Is Human Activity Primarily Responsible for Global Climate Change?"
"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...
[W]hile other forces operate over millions of years, we as humans are having an impact at the same strength as the many of these other forces, but in the timeframe of just a couple of centuries.
The human magnitude of climate change looks more like a meteorite strike than a gradual change."
