Human activities have significantly increased atmospheric CO2 since 1950.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that human activities have significantly increased atmospheric CO2 since 1950?

Yes. One official record states that fossil-fuel carbon discharged as CO2 has risen sharply, with almost three-quarters of the release occurring since 1950, and other sources report a sharp atmospheric CO2 increase over the industrial era. The evidence supports the claim, though several items frame the rise from the industrial revolution or 1958 rather than isolating 1950.
