Summary
It basically gives us an overview of the political and social approaches to the climate change problems, which is not that scary as the daunting statistics but teaches us something practical and doable by the individuals, like ourselves live in this world.
The first part of the lecture gives us an overview of the climate change conundrum, both in a historical and contemporary perspective. In the past or maybe just a few decades before, the leading emitters in the world are predominated by the western countries, that is, developed countries, such as the United States and countries in Europe. However, in today’s context, companying the soaring of the eastern countries, more and more countries especially those in Asia are gaining more weight in the affairs of carbon emissions and climate change. China has outran the United States to be the world’s largest carbon emitter; India will also soon catch up with its huge economy and fast industrializing pace. If other countries like Malaysia, Indonesia in Asia keep developing economy without properly taking care of the environmental issues, Asia would soon be dominating in carbon emission. Nonetheless, the carbon emission per capita in developed world is still considerably high than that in developing world.
Secondly, we need strong governmental or institutional approaches to tackle this problem. The government can invest in clean energy; transform the energy structure, increasing the clean energy portion; Tax the roads or vehicles to control the numbers of cars, or like Mexico City where rules that there is a particular day in a week on which you cannot drive your cars; government can also extend the responsibility of the producers on their products as European Union does.
Lastly, it comes to the individual responsibility. Although maybe one’s efforts seem quite minor in combating climate change, as long as we can do it together, it actually a very powerful force to fight the climate change. We can choose to eat less meat or eat meat that is home-grown, since meat is actually very carbon intensive and by eating home-grown food, we can decrease the carbon emission caused by the transportations in carrying those meat from far abroad.
To conclude, the climate change issue has been a problem we have to focus on and we can do much to help. If everyone can do a small part, we are absolutely able to achieve the goal of containing the climate change in an acceptable range.
LECTURE SUMMARY
In the lectures, the two professors stated respectively upon the present phenomena of global climate change and specific and practical method for ordinary individuals to contribute to the prevention of the warming process. The details and summaries are listed as follows.
Part I:
To begin with, professor Liong define what is actually called “climate change”, it is a concept that ought to be distinguished from the phrase “weather forecasting”, and moreover, predicting the weather change even in only one week is difficult. Therefore, what is supposed to be talked about is a long term average.
Part II:
In this lecture, professor discussed mainly about institutional and political solutions confronting the climate change.
At first, the environmental problems are stated. The largest proportion of green house emission is taken by the carbon dioxide emitted by the burning of fossil fuels and the process of deforestation, worse still, the emission is still increasing in most of the countries. And according the survey, the higher the individual income, the larger amount of the emission.
Shao Tu's Summary of the last Friday lecture: Brief introduction to climate change &modeling
At the beginning of the lecture, a scientific definition of climate was given out by Professor Liong, that it is an average of weather over a long time. More details were followed to illustrate the phenomenon of global warming and how it is related to human activity. Two side by side line charts were used here to prove that the global warming is really happening and it is closely related to our human beings.
After this, a method called SRES Scenarios was introduced to help give out a reasonable assumption of what the future climate would look like. Then a few slides were used to explain the IPCC, an organization from which all the data used came from. Furthermore, a quite impressing opinion was pointed out here that the increase in temperature and rising of sea level were expected even after achieving stabilization of carbon dioxide in the atmosphere. This indicates that only reducing the emission is not enough, more serious problems were waiting for us.
Lastly, GCM and RCM were introduced as two powerful models to help us analyze the climate change. Still data together with graphs were used to illustrate these two models. Conclusions were drawn that the first hand coarse information from Global Climate Model(GCM) might be not adequate for hydrological models, therefore the downscaling approaches are needed to limit the uncertainties. Anyway, this conclusion itself may seem useless for most of us, but on the other hand it showed us how those scientific data came out and made them for convincing.
As a scientist, large amount of data and graphs were used throughout professor Liong Shie-Yun's lecture, those professional terms and definitions may make it confusing and hard to understand. But once you think it over, you can find its logicality and accuracy, so that you will learn something from it and get inspired by the power of science.

Welcome~~~
Happy to meet you here! It is amazing we are from so different places far apart but still be able to meet in a small tutorial room in this country called Singapore, isn't it? Hopefully we are going to have a semester-long study together and possibly life-long friendship~
So, let's work together and have fun!
