Is global warming primarily caused by humans?
Atmospheric carbon dioxide continues to increase due to the undisputed benefits that carbon-based energy brings to humanity. This increase will have some climate impact through CO2's radiation properties. However, fundamental knowledge is meagre here, and our own research indicates that alarming changes in the key observations are not occurring.
