Final answer:
Temperature at the global level is primarily influenced by greenhouse gases, which trap heat in the atmosphere through the greenhouse effect. This natural phenomenon is intensified by human activities such as burning fossil fuels, contributing to global climate change.
Step-by-step explanation:
greenhouse gases:
At the global level, temperature is influenced by greenhouse gases. Temperature at the global level is influenced by greenhouse gases in the atmosphere. Greenhouse gases such as water vapor, carbon dioxide, methane, and ozone trap heat in the atmosphere in a phenomenon known as the greenhouse effect. These gases absorb and emit radiation, which leads to an increase in global temperature.For example, water vapor is the most abundant greenhouse gas and plays a crucial role in the natural greenhouse effect. Temperature affects the overall rates of evaporation and precipitation, which in turn influences the concentration of water vapor in the atmosphere.Human activities can also indirectly influence the concentration of greenhouse gases, such as carbon dioxide, through the burning of fossil fuels.
The Earth's temperature is significantly affected by the greenhouse effect, which is the process by which greenhouse gases such as water vapor, carbon dioxide (CO2), methane (CH4), and ozone trap heat in the atmosphere. These gases absorb infrared radiation from the sun that is re-radiated by Earth's surface and emit it back, heating the atmosphere and the surface. Without this natural phenomenon, Earth would be too cold to sustain current forms of life, as it maintains global temperatures within a life-sustaining range. However, since the Industrial Revolution, human activities have increased the concentration of these gases, particularly CO2, through burning fossil fuels. This has altered the energy balance and is causing global climate change, leading to a rise in global temperatures.
