Question
Chapter 46, Problem 3TY
Summary Introduction
Introduction:
The greenhouse effect warms the Earth. Moreover, human activities are continuously increasing the levels of greenhouse effects. Due to this, the temperature of the Earth’s surface is increasing day by day. Right now, it is considered that the burning of fossil fuel is the reason for the increase in the greenhouse effect.

() According to this data, how many times longer do CFCS
remain in the atmosphere than CO2?
(i) (1) Use values from these graphs to explain why CO2 is
considered to be the main greenhouse gas;

(2) the importance of CFCS to the greenhouse effect
might be greater than their percentage contribution
would suggest.
