Manmade global climate change is real and a threat.
"Many climate scientists agree that sunspots and solar wind could be playing a role in climate change, but the vast majority view it as very minimal and attribute Earth’s warming primarily to emissions from industrial activity—and they have thousands of peer-reviewed studies available to back up that claim." harrytruman Sunspots play a minimal role. As for CO2 levels only being a small part of the greenhouse gases this is true. Neverthless, naturally occuring CO2 is balanced out. Human industry made CO2 is not.
