Issue of Global Warming

The lecture was concentrated on global warming. The three lecturers talked about the issue of global warming in different perspectives while they had something in common. They all regarded global warming as one of the greatest challenges people faced nowadays and they thought that some measure should be taken in response. The first speaker, Prof Palmer talked about the mechanism of how greenhouse gases heat the earth, and then he moved on to talk about the technology of carbon capture and the influences of politics on technology. The second speaker, Prof Sovacool, mainly focus on how to evaluate technologies. He used two examples in order to show that political and economic factors must be taken into consideration when people evaluated a technology, which was exactly the objective of Science Technology System (STS). The last speaker, Dr Bala, talked about the evidence of global warming and the challenges of solving global warming. He also provided us with some feasible actions in response to global warming and climate change.

Among these three educated speakers and their professional talks, I am fascinated by the last speaker, Dr Bala, who has shown some evidence of global warming and the difficulties in solving it. I cannot agree his points of view more. The sign of global warming has becoming more evident especially in recent years. The rising of sea level and the melting of ice in Arctic are good examples. Scientists and researchers have already urged people to concern about this issue. However, few people realize the importance and miserable outcomes of global warming. I think this is why it is difficult to solve the problem of global warming worldwide. People hardly have ideas about what is global warming and why it is so disastrous. Many people think it has nothing to do with them. As a result, it is hard to control this serious issue. Hence, in order to solve this problem, it is important to propaganda the knowledge of global warming. What is more, government should encourage people to make personal contributions. In fact, it is very simple and convenient to take some measure in daily life which can help to reduce the problem of global warming.

As discussed in Dr Bala’s talk, if everyone realizes the urgency of global warming and contributes a little, the problem will be solved and it will be a better world.
