Question 6
1. There are several reasons for climate change, one of which deals with the greenhouse gases. The greenhouse gases are essential to the living things on earth. But when they increase to a certain level they can become dangerous, there has been an increase of these gases causing our climate changes.
2. Human activity is also a contributor to the increase of green house gases. By burning coal, oil and other gases we fuel the greenhouse gases, making them increase by a lot. We are also big contributors of the large amounts of carbon dioxide in the atmosphere.
3. The climate is warming because studies show that global surface tempatures have increased in the last few years. Not all areas around the world are getting warmer though, some are even cooler than usual. But the ten warmest tempatures have occured after 1995.
4. The blizzards in certain parts of the world are not due to global warming, some of these areas have low amounts of carbon dioxide and do not increase the greenhouse gases.
#4 is not exactly correct.
