Global Warming and climate Change







Global Warming and Climate Change
Our world is facing a lot of problems such as crime, problem is Global Warming. We listen about Global warming every day, but most of us didn’t know the meaning . Now I’m going to explain. Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed causa to an increase in average Dioxide (CO2) and many more.
Of cause you going to ask, what is a greenhouse gases and how does it affect our world. When the energy come from the sun to the earth’s weather and climate, heats the earth’s surface, in turn the earth glow with energy back into space, but some atmospheric gases like water vapor, carbon dioxide, and other gases, block some of the outgoing way, and keep hold the heat just like the glass, so that it’s known as greenhouse gases.
There are six kind of green house gases, carbon dioxide (CO2), methane (CH4) (which is 20 times as potent a greenhouse gas as carbon dioxide) and nitrous oxide (N2O), plus three fluorinated industrial gases: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). Water vapor is also considered a greenhouse gas
