Answer:
-18°C
Explanation:
Global warming takes place due to the constant increment of atmospheric gases caused by human activities, and these include CO2, CH4, N20, and CFC. These are commonly known as greenhouse gases because they allow for the major part of solar radiation to enter the atmosphere and heat the surface of the Earth. At the same time, they avert a part of thermal radiation from escaping to space. If these effects caused by greenhouse gases and water did not exist, the average temperature of the Earth would be around -18°C (0°F), but instead, it is about 15°C (59°F).
