What was the highest carbon dioxide level between 400,000 B.C. and 0 A.D.?

Expert Solution & Answer

Summary Introduction

To determine: The highest carbon dioxide level between 400, 000 B.C. and 0 A.D.

Introduction: The carbon dioxide concentration is rising, and the present-day concentration is highest in 15 million years. It is more of as a result of human activities that contributed in increase in carbon dioxide level in the Earth’s atmosphere. The major contribution is by burning of fossil fuels that releases high amounts of carbon in the atmosphere. This impacts climate and ecosystems.

Answer to Problem 1DAA

Correct answer: The highest carbon dioxide level between 400, 000 B.C_.and 0 A.D. is 300 ppm.

Explanation of Solution

Refer Fig. 46.13, “Changes in atmospheric carbon dioxide levels (in parts per million)”, in the textbook. The graphical representation shows the atmospheric carbon dioxide (ppm) measured from deep core samples of Antarctic ice. The air bubbles trapped in the ice gives information regarding the gas content in the Earth’s atmosphere at the time the ice was formed. The oldest ice sample analyzed dates back to more than 400, 000 years. According to the graphical data, the highest level of carbon dioxide between 400, 000 B.C. and 0 A.D was 300 ppm. There were many variations (highs and lows) in the levels during this period.
