How does global warming effect us?
Global Warming not only us but also animals such as Polar Bears. Polar bears lose their habitats and they won't get to eat the seals' and they will die. The cause of this is cars using up to much heat and they exhaust fumes.
"Climate Change" and "Global Warming" are not the same, though related. Global Warming causes Climate Change. With Global Warming we understand the warming of the earth's global temperature. That warming has in turn an effect on the earth's global climate and on more localized climates (like the climate of England or Western US).
Global warming does not alter the natural greenhouse effect. Man alters the natural greenhouse effect by deforestation and by burning fossil fuels (coal, oil and natural gas). This increases the levels of greenhouse gases in the atmosphere, causing an enhanced (or accelerated) greenhouse effect which is causing global warming.
