Question

Global Warming: Why? by Rex Woodbury

Scientists who study climate models and climate patterns are concerned that the Earth's average
temperatures seem to be increasing. They also report that a warm-up of even a few degrees will have far-reaching effects on climate, wildlife, human food production, and fresh water supplies. Why is this happening?
To understand global warming, imagine that our planet is wrapped in a blanket. The blanket
is made up of carbon dioxide and other gases that collect and trap the sun's heat in the Earth's
atmosphere. It's important to understand that this blanket serves as protection from the intensity
of the sun and its dangerous rays. The burning of fossil fuels and other human activities, however,
have changed the make-up of this protective covering. In simple terms, by adding more gases,
we've added more layers, and the blanket traps more heat than it should, heat that changes our
environment.

In the first paragraph, the author points out the problem caused by increasing temperatures and then
asks a question. In the second paragraph, he answers that question by explaining more about the process of global warming.

Answer 1

Focus of Account 1: The concern over increasing temperatures and the far-reaching effects of global warming on climate, wildlife, human food production, and fresh water supplies.

Focus of Account 2: The explanation of global warming and how human activities have changed the make-up of the Earth's protective covering, leading to an increase in trapped heat.

Ideas in Both Accounts: The cause of global warming is the increased trapping of heat due to the changes in the Earth's protective covering caused by human activities, specifically the burning of fossil fuels. The consequences of global warming are far-reaching and have significant impacts on climate, wildlife, human food production, and fresh water supplies. The author's purpose in presenting this information is to explain the science behind global warming and why it is a pressing issue that requires immediate attention and action. The focus of the account is shaped by the author's purpose, which is to inform and raise awareness about the causes and consequences of global warming.
