Final answer:
Anthropogenic heat production in cities increases the urban heat island effect due to additional warmth from human activities. Human activities strengthen the greenhouse effect and contribute to global warming by raising greenhouse gas emissions since the Industrial Revolution.
Step-by-step explanation:
The correct answer to the question regarding anthropogenic heat production in cities is that it increases the urban heat island effect. Anthropogenic heat refers to heat produced by human activities, such as transportation, industrial processes, and heating and cooling of buildings. This heat adds to the usually higher temperatures found in urban areas compared to rural areas, known as the urban heat island effect. The contribution of anthropogenic heat to this phenomenon is significant because human activities create additional warmth that gets trapped by the dense materials and reduced vegetation in urban spaces.
Regarding the impact of human activities on the greenhouse gas effect, society is concerned because these activities strengthen the greenhouse effect by trapping more heat in the atmosphere. Specifically, since the Industrial Revolution, the burning of fossil fuels, such as coal and petroleum, has significantly increased the levels of carbon dioxide and other greenhouse gases in the atmosphere. These gases absorb infrared radiation, leading to a warming effect known as global warming.
Consequently, global temperatures have been steadily increasing since the Industrial Revolution largely as a result of increased greenhouse gas emissions from human activities. This is a global concern as it leads to climate change and impacts weather patterns, ecosystems, and sea levels worldwide.
