Question
Chapter 59.2, Problem 1CC
Summary Introduction
To determine: The reason of seasonal fluctuation in the amount of carbon dioxide in the graph with reference to the figure 59.7b given in the text book.
Introduction: Burning of fossil fuels is a major cause of global warming. These fossil fuels are very high in carbon and results in the release of carbon in the atmosphere when they are burned. The concentration of carbon has increased since industrial revolution over the 200 years ago.
