Detailed explanation-1: -The Earth’s average surface temperature has increased by about 1.8°F (1.0°C) since the late 1800s. Human-caused greenhouse gas emissions are responsible for the observed warming.
Detailed explanation-2: -Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.
Detailed explanation-3: -EVAPORATION. A warmer atmosphere can hold more water vapor. If the climate warms by another one degree Celsius, the atmosphere would be able to hold about 7% more water vapor. Most of that extra water vapor is going to come from the earth through increased evaporation and transpiration.
Detailed explanation-4: -The increase in greenhouse gases from the burning of fossil fuels, agricultural activities, and deforestation, which has caused global average air temperatures to increase.
Detailed explanation-5: -The greenhouse gases lead to increase in temperature near the surface of the earth. This phenomenon is known as Global warming.
