This week I decided to do my current event on global warming. I chose this because lately I have been hearing a lot about global warming. So far, what I know about it is that the world is heating up and melting the glaciers, which is causing the ocean to rise and get colder. It is killing polar bears and other animals that live in areas with a cold climate and it is causing it to be cold in places like Vermont because the wind that comes from the north off the ocean is colder now because the ocean is so cold from the glaciers. Many people would agree that global warming is one of the biggest threats facing our planet today. The cause of global warming is greenhouse gases. Greenhouse gases are gases like water vapor and carbon dioxide. These gases trap the energy radiated back from earth retaining the heat and causing the earth to heat up. Greenhouse gases also cause global dimming. Global dimming is the opposite of global warming. With global dimming, the greenhouse gases cause the clouds to be whiter which causes them to let less of the sun's energy through and reflect most of it back making the earth cooler. For a long time major businesses and companies have put a lot of money and resources into hiding global warming because they were worried that if the truth came out about global warming they would be put out of business because no one would buy their product and or it would become illegal to use their factories that put off so many green house gasses. Now of course that the truth has come out, these businesses are concerned about the issue and are looking for regulation and direction. There are still a few companies though that are trying to undermine the situation. In conclusion, we have been covering up global warming for many years and trying to hide from it and pretend that it is not true, but now that the truth has come out, we need to work fast to be sure that we do not dig a deeper hole than we are already in.
