Yes. We have an instrumental record going back to the late 1800s, and land, sea, air and space-based measurement systems showing that our planet is warming. At this stage, anyone suggesting that the planet isn't warming is just plain wrong.
If the planet is warming then there must be a physical reason. Increasing concentrations of greenhouse gases in the atmosphere produced by us is the cause. Not the sun, urban heat island effects, orbital variations, galactic cosmic rays, coming out of an ice age, or any of the less plausible, studied, and discounted explanations being mooted.
I find it odd that skeptics are willing to argue any number of possible explanations but not the CO2 one despite the fact we can measure CO2 rising in the atmosphere, can link that rise to our activities, can measure the increase in radiative forcing it causes, can see the effect in spectra obtained by satellites, and find that data almost exactly in keeping with what the laws of physics predicted.
