[0] 29 [Skeptic Argument] “Increasing CO2 has little to no effect” [Paragraph] An enhanced greenhouse effect from CO2 has been confirmed by multiple lines of empirical evidence. Satellite measurements of infrared spectra over the past 40 years observe less energy escaping to space at the wavelengths associated with CO2. Surface measurements find more downward infrared radiation warming the planet’s surface. This provides a direct, empirical causal link between CO2 and global warming. [One Liner] 
The strong CO2 effect has been observed by many different measurements.
