Extreme warming forces climate scientists to add hot pink to temperature map

Raul # 1, I’m afraid you don’t get it right. Solar radiation is mostly visible light and near infrared. This is absorbed by land and sea. Land and sea radiate the energy away (obviously they don’t keep getting hater forever). This radiation is longwave infrared radiation, also called thermal infrared. Greenhouse gasses in the atmosphere (mainly water vapor and CO2) absorb this radiation. Molecules of these gases then radiate longwave IR again, but in a random direction. When the concentration of greenhouse gasses is higher, more of this radiation goes back to the ground or the ocean and less of it escapes into space, until the earth warms up a bit and again radiates enough out the top of the atmosphere to balance the incoming energy.
