The term global warming means what it says. Global warming is when the overall temperature of the planet, or globe, increase. This raises the temperature, even if only one or two degrees, can cause dramatic changes in the climate of the planet. This major change in climate can be so severe that the species could be extinct all because of inability to cope with changes in their climate. Why is this problem of people? That should worry people because it is human activity that causes rapid increase in average temperature of the planet. What makes the situation worse is that many people all laugh and say it is a myth. Here are four facts about global warming that might help to wake some of those individuals. Fact one: the world’s leading scientists said global warming is real and have evidence supporting his belief that human activity causes average temperatures to rise. In fact, human activity is causing this increase are the transportation methods used by most people, as well as factories and industries that pump toxins into the air. The main culprit is carbon, which is caused by the burning of fossil fuels by cars, factories and use of energy used to produce electricity and heat. The proof is in the world around us, such as melting polar ice caps, and many species being pushed to the endangered list due to loss of habitat and food special. Fact two: how to slow global warming, countries need to reduce carbon emissions they put into the air, or find alternatives that do not release carbon into the air. Planting trees and finding natural alternatives for energy they need is probably the best way to begin to help fight global warming. Fact three: global warming of the earth is experiencing now is not normal. This is a rapidly global warming is caused by burning fossil fuels and pump carbon man in the air. Abnormally high levels of carbon in the atmosphere to retain heat, causing the average temperature on Earth increases. Scientists have ruled out other potential greenhouse gases, but have found that people are, in fact, a major contributor. Fact four: Global warming is a completely different problem that hole in the ozone layer. Hole ozone layer is caused by synthetic chemicals such as chlorofluorocarbons (CFCs). Global warming is caused by a buildup of carbon in the atmosphere.
