So what exactly is global warming? Picture in your mind that you are asleep in bed with lots of blankets covering you suddenly, you wake up all hot and sweaty, so you kick off the covers. Cool air hits your legs. You feel much better and you fall back to sleep again. Now picture the earth. The heat come from the sun get trapped under the blanket and the earth begin feel very hot, but the earth cannot just kick off the cover to cool itself down. This is Global Warming.
People all over the world have burned more and more fossil fuels such as coal, oil, and natural gas. These fuels are nonrenewable. Fossil fuels also release pollutants, including carbon dioxide and other gases, all of these things contribute to global warming.
All the gases in the atmosphere, carbon dioxide (CO2) contributes the most to global warming, but CO2 is also necessary to our life. CO2 is very bad for humans and the entire living thing on planet earth. Every living thing on planet earth is part of natural carbon cycle. This is how it has always worked, but recently we have been asking too much of the carbon cycle; Cars, factories, and electric power have been putting too much of this buried carbon into our atmosphere.
Since human health depends on good environmental conditions and is linked to climate, experts believe that global warming will hurt human life in several different ways. Air pollution, poor soil conditions, and inadequate food and water would increase health problems and the spared of disease will also largely increase.
The intergovernmental panel on climate change lists, lots species as being particularly threatened by global warming: the Emperor penguin, Polar bears, birds, Ringed seals, the Arctic fox, the Beluga whale, Staghorn corals, Salmon, and other species.
Global Warming will impact nature and human. The climate will have a huge difference after five years from today.
