I am rather impressed during lecture 2. All lectures have emphasized the consequences of global warming and how to ease global warming.
There are many consequences of global warming. Due to global warming, the temperature of earth increases tremendously. The melting of iceberg has resulted in increase in sea level. Hence, coastal areas are easily flooded. Countries like Singapore can be flooded if we keep on ignoring global warming. Apart from that, many new-founded viruses are also the result of global warming; such as avian flu and SARS. The damage of these viruses is well-known. Thousands of family are broken. Children are orphaned. In addition, the frequency of natural disasters across the world has reached an unprecedented high. All these problems are the result of global warming. That leads us to a serious question; how to ease global warming both as individual and as group.
According to Prof Andrew Palmer, global warming can be eased by increasing fuel efficiency and propagate conservation of energy. This can be achieved if government play his role well. Government can implement policies which help to reduce green house effect. Such as, increasing tax for vehicles that produce more carbon dioxide and reducing tax for environment friendly vehicles such as hybrid vehicles. There are many ways government could do to ease global warming, however, government alone cannot achieve it, not without the support people. We as individual should do our part. We should switch off electrical appliance when we are away. Not only that, we should also recognize new 4 Rs; refuse, reduce, reused and recycle. Refuse means that refusing purchasing cars and electrical appliances which are luxury.
Climate change is increasingly recognized as one of the most serious threats to humankind. However, there are still quite a number of people who either deny the fact of global warming or feel extremely hopeless for global warming. I believe that these kinds of attitude should not be encouraged. We should accept the world as it is, not as we might like it to be and do our best to make it a better place to live.
I believe that the solutions are in our hands, we can do and should do thing about global warming before it is too late.

Global warming
Global warming has become one of most challenging problems for mankind. We can either ignore it and suffer the consequences or pay attention to it and make sure that the problem is addressed. There are many ways to ease global warming as an individual or a group. Government plays big role when tackling global warming. Policies have to be implemented to reduce the problem of global warming.
One policy that should be implemented is to increase car tax for those cars which produce too much emission. Car emission is a major contributor to global warming. By putting more tax on these kinds of cars will then make hybrid cars and electrical cars cheaper by comparison. In this case, people are encouraged to drive cars which are more environmental friendly which could result in less care emission. By doing so it could help to reduce the problem of global warming.
Another policy that could contribute to reduce the problem of global warming is to increase the efficiency of fuel. Reason being simple, increase the efficiency of fuel could reduce the usage of fuel which ultimately result in less emission of carbon dioxide.
The most fundamental policy that should be implemented is to educate people world widely. Because everyone is responsible for global warming and it can be solve if we are all willing to do so. So if all individuals do his part, the problem can be solved. There are many things we can do to ease global warming as individual. For example, use more efficient light bulb. Close all electrical appliances when they are not in used. Practices the four Rs which are refuse, reduce, reuse and recycle. Refuse means that refuse to buy cars and foods which require long transportation.
In conclusion, the solutions of global warming are in our hands, we only need determination. If we choose to ignore global warming, we could witness a collision between civilization and earth in not far future. Who will win, we all know.
