Global Warming
Effects on Earth

Global warming has become one of the biggest effects on earth’s life for many years now. Every day there are more and more reason’s causing this huge effect on life. Global warming can become a huge danger in the future with the drastic increase it has been becoming over the years. Global warming is caused by reasons like the sun, and the greenhouses effect.
Global warming is causes many problems. Wild life is being affected, sea levels are rising, glaciers are melting, and some forests are drying out. Every affect this causes on earths wild life makes it harder and harder for us to live. In order for people to survive we need a steady ecosystem to live in. Global warming affects all parts of the earth and travels right around in its rotation. The sun is a part of why the earth has been rising in temperatures causing glaciers to melt and the rising of our oceans water levels. This forces wild life to fight to survive and migrate around finding new homes to live in. Humans are the biggest cause to global warming over the past 100 plus years.
Greenhouses gases are released into the atmosphere letting light through but trapping heat. Sun light comes down to the earth where it can be absorbed and releases heat back into atmosphere. Greenhouses gases then trapping some of the heat while the rest escapes into space causing the “Greenhouse Effect”. The more greenhouses gases we have the more heat will be trapped in our atmosphere enhancing global warming to the max. The greenhouse effect has been known about for almost hundred years but was thought of differently at that time. “Scientists have known about the greenhouse effect since 1824, when Joseph Fourier calculated that the Earth would be much colder if it had no atmosphere” (http://environment.nationalgeographic.com). It was known that these greenhouse gases helps stabile earths heat in the atmosphere making the climate livable. A scientist then discovered that without an atmosphere earth’s temperature would be a lot colder making living condition pretty close to impossible. “In 1895, the Swedish chemist Svante Arrhenius discovered that humans could enhance the greenhouse effect by making carbon dioxide, a greenhouse gas” (http://environment.nationalgeographic.com). Levels of greenhouse gases have fluctuated up and down over earth’s history. These gases have been fairly constant for few thousand years keeping earth’s global average temperature also fairly consistent. Recently things have been different because humans are enhancing the greenhouse effect by burning fossil fuels and other greenhouse emissions which will warm the earth therefore increasing global warming.
Sense the industrial revolution humans have increased the amount carbon dioxide in earth’s atmosphere more than a third, which is one of earth’s major greenhouse gases. This large of a change has historically taken thousands of years but have now been occurring within decades. The rapid increase in all these greenhouse gases is causing huge problems in wild life’s living. This drastic rise is changing Earth’s climate faster than some living things may be able to adapt. Wild fires are also becoming more frequent killing off a lot of wildlife. Also the Earth’s remaining ice sheets are beginning to melt, causing extra water which potentially raises sea levels significantly. Along with rising sea levels come extreme weather conditions like major storms, more rain, longer and drier droughts, and changes in living conditions where plants and animals can live. Sense temperature recordings were available eleven of the twelve hottest years occurred recently between 1995 and 2006 stating that global warming is at its highest point ever been.
Global warming can also have some positive effects on some of Earth’s regions but more often negative effects damaging our environment. Things like some crops and plants can respond favorably. Plants and crops can start to grow tremendously and use more water efficiently. High temperatures can also enhance some plants and crops growing best then leading to the makeup of natural plant communities. Global warming can also be compared to other planets like Venus and Mars in ways of what can happen to Earth. Mars does not have enough greenhouse effect with a very thin atmosphere nearly all carbon dioxide with very little atmospheric pressure. With such little greenhouse effect Mars has a frozen surface with no signs of life. Meanwhile Venus is the opposite with too much greenhouse effect. The carbon dioxide level in Venus’s atmosphere is about 300 times greater than Earth and Mars creating a surface temperature hot enough to melt led also leaving no signs of life. If global warming continues at the rate it is now Earth could eventually kill off all life. This has been perhaps the most complicated issue facing world leaders because could end all of humanity.
Global Warming has seen to be a very dangerous issue to life on Earth. If this continues to increase there will be very little to no life at all. Humans are our number one cause for this controversial issue but also are the only way to change it creating existing life on Earth.
