1. Explain that infrared radiation is absorbed by C=O, O–H and C–H bonds in CO 2, H 2 O and CH 4, and this contributes to global warming. Explain that the greenhouse effect of a given gas is dependent both on its atmospheric concentration and its ability to absorb infrared radiation.

4. Explain the importance of controlling global warming caused by atmospheric increases in greenhouse gases. Outline the role played by chemists through the provision of scientific evidence that global warming is taking place. Understand the role of chemists in monitoring progress of initiatives such as the Kyoto protocol. Week 27 © Pearson Education Ltd 2008 This document may have been altered from the original

5. Outline how chemists investigate solutions to environmental problems, such as carbon capture and storage (CCS). Understand the removal of waste carbon dioxide as a liquid injected deep in the oceans. Outline carbon storage in deep geological formations, by reaction with metal oxides to form stable carbonate minerals.
