What Do You Think about Climate Change?

I read a sence of serious article on BBC.

The UK's Disasters Emergency Committee has claimed that country should take actions on climate change, and the protesters marched in Warsaw. The committee said that Typhoon Haiyan was a indication of the future for so many people who will be in danger of natural disasters.

I feel that climate is changing, and as time moves on, more and more news about abnomal weather are broadcasted. Recentry a big typhoon attackted Vietnam, and some people died because of the typhoon. In Japan, it is about 25 times that typhoon come for a year. Each times it happens, people are at risk. In additon, abnomal weather causes the biggest and strongest typhoon, heavy rain, hurricanes, and so on. One reason why abnomal weather happen is emmition of CO2, so we sould take actions to reduce it. If we could do it, we might see the better future for us. After I read this article, I thought about our future.
