Climate is the weather conditions over a long term. For millions of years, the earth kept changing between hot and cold, and wet and dry. As the earth warmed and cooled, plants and animals appeared and disappeared. People have had to change their way of life many times as plant and animal life changed. Since the industrial revolution, the humans built many factories and invented lots of electronic devices. They emit harmful gases called greenhouse gases like carbon dioxides and ozone, which affects our planet. However, it is difficult for people to recognize the effects because the process of climate change takes a long time. Furthermore, people think it is so far away. For example, as in Antarctica, all the icebergs are melting, which is ruining habitats for polar bears and ruining the ecosystem in general. But people do not really think about Antarctica because nobody really lives there. Even so, climate change is clearly occurring and caused largely by human activities such as the release of greenhouse gases from burning fossil fuels, are major factors in the current environmental changes.
Most climate scientists agree that the main cause of the climate change trend is human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from the earth toward space. Substantially increased concentration of greenhouse gases can have significant impacts on climate and severe aftermath for the earth. There are two main sources of…
