Effects of Global warming

Global warming or “greenhouse effect” is an average increase in the temperature of the atmosphere near the Earth’s surface, which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes, both natural and human. In common usage, “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities. The atmosphere consists of several “greenhouse gases”, some of them ate natural like carbon dioxide (CO2), methane, and nitrous oxide and these greenhouse gases cause the same effect as the glass does in a normal greenhouse. The greenhouse of the Earth works as following: when the heat from the sun hits the atmosphere surrounding Earth, some of the heat is reflected back into the universe. The rest of the heat is absorbed by the surface of the Earth. The heated Earth now emits heat back into the atmosphere, where a part of it is absorbed and reflected back to the surface by the greenhouse gases. This heat is now trapped in the atmosphere, heating the temperature of the Earth¹. Effects of global warming noted around the world are tornedos, tsunami, ice melting, rise of the sea level and animal extinction.

One of the effects of global warming is disappearing of many animal species. A certain number of all species are being affected physiologically by global warming. There is evidence that some species are physiologically vulnerable to temperature spikes. For example, the green ringtail possum, endemic specie of north Queensland's tropical rainforests in Australia, cannot control its body temperature when the ambient temperature rises above 86º F. An extended heat wave in north Queensland could kill off a large part of its population².

 Another species affected by global warming are the coral reefs. If we do not protect the coral reefs, they might join the group of endemic species to. The report, by the Australian...
