Carbon dioxide is doing both these things.
increasing the CO2 concentration in the atmosphere

The greenhouse effect warms the gases in the atmosphere.
Greenhouse Effect
The greenhouse effect comes about when greenhouse gases in the atmosphere capture heat rising from the surface of the planet. As the moon has no atmosphere, it could not have a greenhouse effect. So the answer is: The earth.

An enhanced (or accelerated) greenhouse effect which is causing global warming.
it allows solar radiation to penetrate to the surface!
The greenhouse effect warms the gases in the atmosphere.
Greenhouse gases (carbon dioxide and methane, mostly) cause global warming by increasing their levels in the atmosphere. This turns the benign greenhouse effect into an accelerated greenhouse effect which is causing global warming.
The natural greenhouse effect is not raising sea levels, but the enhanced (or accelerated) greenhouse effect which is causing global warming, is. The warmer atmosphere is melting glaciers and expanding the water in the oceans, so sea levels are rising.
The Greenhouse Effect.
EarthVenusMarsThe greenhouse effect occurs on every planet with an atmosphere (including Earth). On Venus, there is a runaway greenhouse effect causing temperatures high enough to melt lead.Mars has a greenhouse effect that is weak because of its thin atmosphere.
In the atmosphere. The greenhouse effect refers to the situation in the atmosphere where gases hold on to the heat rising from the earth.
