Article: We know that the earth has become warmer over the last century. The Intergovernmental Panel on Climate Change (IPCC), a group established by the World Meteorological Organization and the United Nations Environment Program, reports that the average surface temperature of the earth has increased during the twentieth century by 0.6deg _ 0.2degC.(The _ 0.2degC means that the increase might be as small as 0.4degC or as great as 0.8degC). This may seem like a small shift, but although regional and short--term temperatures do fluctuate over a wide range, global temperatures are generally quite stable. In fact, the difference between today's average global temperature and the average global temperature during the last Ice Age is only about 5 degrees C. Indeed, it's warmer today around the world than at any time during the past 1,000years, and the warmest years of the previous century have occurred within the past decade. We also know that human activities--primarily the burning of fossil fuels--have increased the greenhouse gas content of the earth's atmosphere significantly over the same period. Carbon dioxide is one of the most important greenhouse gases, which trap heat near the planet's surface. The vast majority of climate researchers agree with these overall findings. The scientific disagreements that do still exist primarily concern detailed aspects of the processes that make up these largely accepted general themes. You can think of this website as a window into the world of scientific research. In this primer, you'll find a general discussion of the physical processes underlying the earth's climate, an outline of the kinds of data that may shed light on how the climate is changing--and the role of human activity in these changes--and a description a some of the questions and uncertainties that researchers continue to explore. This primer is organized into four interconnected sections: the Atmosphere; the Hydrosphere ; the Cryosphere ; and the Biosphere .
Answer: engages in the climate and changes about the earth.
We know from the text that "IPCC" _ .

Article: In today's Internet age, online games can be a change from the pressure of school and work. However, they can also cause problems and unhealthy addictions. This is most clearly seen in the example of South Korea. This country has the world's highest percentage of high-speed Internet services. It also has a high number of game players who are addicted to online games. In 2004, a young man died after playing online games almost nonstop for 86 hours. A 12-year-old boy stole $16,000 from his father to continue online games which he could not get away from. Such problems are spreading to other parts of Asia as well. In 2005, it was reported that about 80 percent of China's 13.8 million online game players were under 25. And many of these were said to be addicted. Such numbers point toward a growing problem among Chinese youth. Dr. Sue-Huei Chen, a psychologist, discovered some signs of at-risk people. Such people often go online to escape from their problems. And they usually have no friendship or good social skills. They feel the need to spend more and more time online, so they may be absent from school or family. And they become upset if anyone tries to shorten their online game playing.

Article: People have always been wondering about what our future will look like. Go on reading this text, and you will know what will happen in the next fifty years. How can we know what the future will look like? To be able to understand the future, you must know the past. What has taken us to where we are today and what has changed along the way? The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago. Will this change in the next 150 years? No. What inventions have really made a difference in the last 150 years? In the past years, the inventions that have affected most people around the world for everyday living are the telephone, electricity, radio, television, computer, the car and the ability to communicate through the Internet. Then we of course have a lot of inventions that have made life easier, like new medicine, faster transports etc. In general, human beings have been working hard in the last 150 years to make the inventions so that they will be able to get control of the time and the world. Since there is still much to do in this area, this will be the focus at least for the next 150 years. Why do we need to predict the future? Predicting the future is important for two reasons first we need to start to think about what kind of future we would like for ourselves and to pass on to the next generation, and then we need to know what decisions we need to make today that will give the best result in the future.
Answer: it easy for us to live
