Chapter 4.12, Problem 4.50YT

Interpretation Introduction

Interpretation: The British Labour party in 1997, under the leadership of Tony Blair, committed to cut British Greenhouse gas emissions 20% by 2010. This is significantly more than the 12.5% required by the Kyoto treaty. Check whether Britain meet its goal or not. A short report on the British experience in reducing greenhouse gases has to be written, and have other countries been able to reduce their emissions significantly since 1997.

Concept Introduction:

• • Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming.

Examples: $C{O}_2,C{H}_4\mathrm{..}$

• • Greenhouse effect: The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat.
• • Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth.
