If the greenhouse effect were to completely disappear, what would happen to earth?

The greenhouse effect is necessary to explain why weather occurs. The climate of the Earth is greatly affected by two opposing processes: the greenhouse effect and atmospheric convection. The greenhouse effect is acting to warm the lower atmosphere and cool the upper atmosphere while the atmospheric convention (composed of thermals, clouds, precipitation) is cooling the lower atmosphere and warms the upper atmosphere). The greenhouse effect warms the Earth’s surface, but very few people are aware that weather processes greatly limit that warming. In the absence of greenhouse effect, the Earth will be left without weather.
