Only partially, by warm winds. Mainly radiation from our Sun gives us heat.
the air is heated by the sun directly
themosphere
Oceans have a constant heating and cooling cycle to maintain the Earth's temperature. They absorb carbon dioxide from the atmosphere which reduces the temperature. They all emit heat that is absorbed from sunlight increasing the temperature.
Greenhouse gases absorb heat rising from the surface of the earth. These warmed gases radiate heat in all directions, including back onto the earth, heating the atmosphere. So the heat is not lost to space, but instead builds up in the atmosphere where it heats the earth as well. they trap the heat from the sun that is reflected by the earth
Greenhouse gases trap infrared heat (from the sun) rising from the surface of the earth. More greenhouse gases trap more heat, and this is the situation now. Increasing levels of carbon dioxide (CO2) in particular are trapping more heat and causing a global warming.
Thermosphere shields us from radiation that the sun emits. That is its main job. It serves as a protective shield against the x-ray and UV radiation being emitted by the sun and keeps earth's temperature in which living things can survive. Without it, the earth will be destroyed by radiation heat.
themosphere
The sun... and the earth's mantle. The surface of the earth is mainly warmed by radiation from the sun - but we also get some heat through the ground - from the molten mantle underneath the Earth' crust.

The atmosphere helps keep earth's surface warm, but does not generate heat itself. The earth is warmed primarily by solar radiation (heat from the sun), and to a lesser extent by the slow decay of long lived heavy isotopes within earth's mantle and core.

Heat from inside the Earth is called geothermal heat.
Earth's atmosphere is mainly heated from the ground up because the heat is absorbed into the ground. The warmed surface of the earth then emits heat as infrared radiation which rises into the atmosphere. There the greenhouse gases like water vapour, carbon dioxide and methane absorb and hold the heat.
