Answer:
The car example is an analogy for the greenhouse effect.
Explanation:
The greenhouse effect is a natural process that warms the Earth’s surface, working similarly to a greenhouse (or a car, in the exposed example), and that is why it receives the name.
The sun energy gets into the earth through the atmosphere, and changes to caloric energy warming up the earth's surface. Some of this energy is reflected space, and the rest is absorbed by the land, ocean, and the atmospheric gases that trap the heat.
Greenhouse gases in the atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons.
In the right proportion, these gases ensure the atmosphere to hold enough heat to support life on the planet. Without them, there would be a huge loss of caloric energy, and life as we know it would be impossible. That means that under strictly natural conditions, the greenhouse effect is indispensable for life.
The problem arises with excessive human activities, such as burning fossil fuels (coal, oil and natural gas), agriculture and land clearing. These activities increase even more the concentrations of gases, which trap too much heat and alter the natural systems. This is what is driving to more extreme weather and climate change that involves different impacts, such as inundations, an increase in precipitation, an increase in temperature, erosion, loss of biodiversity, and others.
With human activities, carbon dioxide concentrations have been increasing constantly over the years. Burning fossil fuels and forest/jungle destruction are two of the principal causes of carbon dioxide increase. When trees are cut down, biomass oxidation liberates huge gas amounts, and gas absorption by trees for photosynthesis is interrupted. This increases the amounts of carbon dioxide in the atmosphere which helps to retain more caloric energy, and therefore increasing temperature on the earth.
