Summary Introduction

To determine: Whether the rise in carbon dioxide level between 1800 and 1975 was larger or smaller than the rise in between 1980 and 2013.

Introduction: The carbon dioxide concentration is rising and the present day concentration is highest in 15 million years. It is more as a result of human activities that contributed for the increase in carbon dioxide level in Earth’s atmosphere. The major contribution occurs by burning of fossil fuels that release high amounts of carbon in the atmosphere. The Industrial Revolution occurred as a transition with a dramatic increase in the carbon dioxide levels.
