Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe. Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate (遷徙) north.

Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.

According to Science Daily, a new study predicts that by the year 2100, many of today’s familiar climates will be replaced by climates unknown in today’s world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.

Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn’t matter what is causing it, but rather, what can be done about it. What’s more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.

However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data.

In Chinese we say,"Your handwriting says a lot about you."But in the eyes of South African photographer John Thackwray,someone's bedroom can do just the same thing.

Thackwray,30,first had the idea of taking pictures of people's bedrooms six years ago,because he was curious how young people born in the 1980s and 1990s lived their lives.And he started with his friends' in Paris.

From the layout of the rooms and the little items in them,you can not only see how different people's lifestyles and personalities are,but also get an insight into how unequal the world is and how traditions are replaced by new technology.

Now Thackwray has put all his photos into a book named My Room Project.Each photo in the book comes with the name,age and job of its owner,and they are arranged in the order of his travels.But Thackwray got a lot more from the project than the chance to publish a book.He also saw a lot of things,met a lot of people and had many great experiences.
