Textbook Problem

Discuss Concepts Some politicians question whether the recent increase in atmospheric temperature results from our release of greenhouse gases into the atmosphere. They argue that atmospheric temperature has fluctuated widely over Earth’s history, and the changing temperature is just part of a historical trend. What information would allow you to refute or confirm their hypothesis? In addition, describe the pros and cons of reducing greenhouse gases as soon as possible versus taking a “wait and see” approach to this question.

Summary Introduction

To review:

The information needed to refute or confirm the hypothesis that increase in atmospheric temperature is a part of a historical trend and is not due to the release of greenhouse gases. Describe the pros and cons of reducing greenhouse gases as soon as possible versus taking the “wait and see” approach.

Introduction:

Greenhouse gases are the gases present in the earth’s atmosphere that trap the infrared radiations emitted from the earth’s surface. Carbon dioxide, methane, oxides of nitrogen, ozone, and water vapor are examples of greenhouse gases.

Explanation

Increase in atmospheric temperature is a part of a historical trend and is not due to the release of greenhouse gases. To refute this, we need to collect data of the concentration of greenhouse gases like carbon dioxide in the last 100 years and compare it with the trend in the increase in temperature. A steady increase in carbon dioxide gas concentration along with an increase in atmospheric temperature during the last 100 years would prove that increase in atmospheric temperature is not a part of a historical trend and is due to the release of greenhouse gases.

Increase in greenhouse gases causes global warming, due to which polar ice caps are melting and sea levels are rising thus causing floods...
