NO! It has been known for over 100 years.

Another line of evidence is the reports of economic activity
put out by (nearly) all governments, taking pride in how much
fossil carbon was extracted from the ground each year. Using
these, the usual estimate is that humans have added about
500 billion tonnes of carbon to the active carbon cycle in the
last 250 years.
So multiple lines of evidence demonstrate that the
additional carbon is anthropogenic in origin. Seems
completely scientific to me...
