I don't think there is one, in our solar system. Mars has that type of atmosphere, but Mars has a solid surface.
Venus.
Venus.
Venus has a thick atmosphere composed mostly of carbon dioxide (CO2). This carbon dioxide is found throughout the atmosphere of the planet, with the highest concentration occurring in the lower atmosphere. It is estimated to make up about 96.5% of the atmosphere.

Venus has an atmosphere that is 96.5% carbon dioxide, making it the planet with the highest concentration of carbon dioxide in our solar system.
Venus has a thick carbon dioxide atmosphere, making up about 96.5% of its atmosphere. This high concentration of carbon dioxide contributes to the intense greenhouse effect on the planet, resulting in surface temperatures hot enough to melt lead.

Venus.
Venus has a dense carbon dioxide atmosphere with surface temperatures that can exceed 800 degrees Fahrenheit (427 degrees Celsius).
Venus has a dense carbon dioxide atmosphere and high surface temperatures, with an average surface temperature of about 467 degrees Celsius (872 degrees Fahrenheit). This extreme greenhouse effect is due to the trapping of heat by the carbon dioxide in the atmosphere.
Venus has a thick atmosphere composed mostly of carbon dioxide (CO2). This carbon dioxide is found throughout the atmosphere of the planet, with the highest concentration occurring in the lower atmosphere. It is estimated to make up about 96.5% of the atmosphere.
The planet may experience wide temperature extremes due to the thin atmosphere's inability to retain heat. The presence of carbon dioxide in the atmosphere may contribute to a greenhouse effect, further influencing the planet's climate. The lack of a thick atmosphere may also leave the surface exposed to harmful solar radiation.
Venus has the most carbon dioxide atmosphere of any planet in the solar system, with about 96.5% of its atmosphere composed of carbon dioxide. This thick atmosphere contributes to the planet's extreme greenhouse effect and high surface temperatures.
mars
That would be Venus. Its dense carbon dioxide atmosphere traps heat using the "greenhouse effect", making the temperatures so high that the surface of the planet is soft and melted.
Venus has a hot, turbulent atmosphere dominated by carbon dioxide. The thick atmosphere traps heat, creating surface temperatures high enough to melt lead.
