This is true. The greenhouse effect on earth holds back heat escaping from the earth.
greenhouse
The greenhouse effect prevents heat escaping into space. Increased greenhouse gas levels means that more heat is retained. This affects the balance by making the earth warmer.
Gases in the atmosphere prevent heat from escaping.

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.
Only Venus and Earth have a greenhouse effect because they have a substantial atmosphere. Venus actually has a runaway greenhouse effect causing its surface temperatures to rise to 450 Celsius.
This is the greenhouse effect.
Two other planets besides Earth.Venus has a runaway greenhouse effect, with most of its atmosphere carbon dioxide, and a temperature of 460° Celsius.Mars has a very faint greenhouse effect, with a little carbon dioxide, but hardly any atmosphere at all.Saturn's largest moon, Titan, has a greenhouse effect, with large concentrations of methane.
Yes, carbon dioxide (CO2) is one of the greenhouse gases. It absorbs heat (infrared radiation) rising from the surface of the earth and prevents some of it escaping to space. The build up of carbon dioxide in the atmosphere is contributing to the enhanced (or accelerated) greenhouse effect which is causing global warming.
Carbon dioxide, methane, nitrous oxide and CFCs (chlorofluorocarbons) trap infrared radiation (heat) causing a greenhouse effect.
