False: > Changes is solar activity (sun spot cycles) and underwater volcanic activity aren't really incorporated into the climate scientists' models
True: The contributions from both solar activity and volcanoes are estimated, and the models do calculate and compare these inputs too. Everybody can see it here:
Conclusion: It's the CO2. And CO2 is contributing with more than 100%. It's true, the other activities add a little of cooling, so without the other contributions, just CO2 would make everything even warmer.
As stated there: "The computer model that generated the results for this graphic is called "ModelE2," and was created by NASA's Goddard Institute for Space Studies (GISS) , which has been a leader in climate projections for a generation."
