1. Climate change is caused by the release of greenhouse gases into our surroundings. When these gases rise up into the layers of the atmosphere, they absorb the heat in the air, and trap the heat down in the lower layers of our atmosphere. While some of this activity is good, and keeps climates from becoming too freezing, there can be too much buildup, which causes certain climates to overheat and have extreme changes in climate. So, in a sense, the greenhouse effect is the cause and prevention of climate change.
2. Because humans are constantly releasing large amounts of carbon dioxide into the air when we use coal, oil, and any other fossil fuels, we are a large contributor to the greenhouse effect. This is what is essentially causing the climate change, so this leads us to believe that humans are one of the largest contributing factors when it comes to the global climate change.
3. For the most part, the global climate is heating up. Over the past 200 years, the overall climate has increased by about .74 degrees Celsius, and even in the past 50 years, it has gone up about .13 degrees Celsius, which is even more rapidly than in years past.
4. Even though the general climate of the globe is heating up, the warming isn't all at the same time, or in the same place. In areas like the east coast of the U.S. and the North Atlantic, the climate is actually cooling. This change, however, is still due to the greenhouse gases, or lack thereof, in our atmosphere.
