INTRODUCTION

This investigation is about the changes in climate and if human/anthropogenic causes are the reason for its change, and to what extent they are responsible. This is an issue because a change in climate has an immediate effect on every aspect of our lives. Due to this, it is critical that understand what effect we are having on the environment and to the future of life on earth.

CHEMICAL BACKGROUND

The burning of Fossil Fuels plays a huge part in climate change. (Evans, McCann, & Morton, 2012) This is because the burning of fossil fuels releases greenhouse gases. The greenhouse gases contribute to the warming of the lower atmosphere and hence cause a change in climate. When gas, coal and oil are burned it releases a heat absorbing primary pollutant called carbon dioxide (CO2). Other greenhouse gases include Methane (CH4), Water vapor (H2O) and Nitrous oxide (N2O). (department of the environment, 2014) Carbon dioxide is classified as one of the main anthropogenic greenhouse gases known. (Shaftel, 2015)

The current levels of CO2 in the atmosphere were measured at 400.71ppm this year. This is an increase of 22.5ppm since January 2005. (Shaftel, 2015) Over the last decade the concentrations of CO2 have approximately raised around 2ppm each year. (Roberts, 2014) The growing amount of carbon dioxide in the last decade can be summarised by figure 1.

Enormous amounts of CO2 are continuously exchanged between the atmosphere; oceans and land fill/plants during…
