3rd Entry

On the 30th January 09, in EG1471 lecture, three lecturers delivered to the students important and interesting information on climate change. Each of them have their respective ways and stands on what we can do from our part to save our environment.

Dr Andrew Palmer of Center for Offshore Research and Engineering was the first of the three lecturers to give his speech. He told us about the increase of carbon dioxide as compared to before. The increase of carbon dioxide have caused global warming around the world. Through studies that he had done, Dr Andrew Palmer gave us examples on how we could reduce the carbon dioxide emission level, example using natural gases and resources (Solar or Wind energy), capturing and storing carbon dioxide under the sea.

Next, Mr. Savacool delivered his speech on Using STS to Address Energy Problems. He used case studies to present and demonstrate to us the topic. In my opinion, his method of presenting was more interesting. As we could easily relate the problem and find a proper solution. He explained to us about the issue between USA and Kyoto Protocol and reasons behind why USA did not sign the Protocol in the end.

The last lecturer is Dr. Rajasekhar Bala and he touched on climate change in terms of assessment and mitigation. He mentioned that the earth's atmosphere is getting warmer because of human activities. The main causes are due to greenhouse gases that prevent heat to escape. They are mainly water vapor, carbon dioxide, methane and nitrous oxide. Without these gases, the earth would not be so warm. He also mentioned signs that suggest Global Warming is occurring and its possible effects and consequences. The rate of climate change could be slowed down by increasing energy efficiency, use renewable energy resources and reducing greenhouse gas emissions. Some basic approaches that Dr Bala presented in dealing climate change are drastically reducing greenhouse gas emissions and developing strategies to reduce its harmful effects.

To conclude, I found the lecture interesting. However, the topic that amazed me most was the use of membrane to store carbon dioxide because it was the first time I heard of it. I did understand more on Global Warming issue after attending the lecture.
