Global warming is a war that we should not get involved with because we will lose if changes aren’t made soon. Global warming is the rapid increase in earth’s average surface temperature over the past century due to the fact that greenhouse gases are being released into the atmosphere increasing the earth’s average temperature (EarthObservatory.NASA.org). There are many contributing factors that play a role into the cause of global warming. Greenhouse gasses are gasses such as Carbon Dioxide, Methane, Nitrous Oxide, and F-gasses that trap heat in the atmosphere. The heat that is trapped in the earth’s atmosphere is a slowly melting glaciers, cause sea levels to rise and is messing with the weather patterns.
The hard face is that despite what many nations, companies, cities and people are starting to do to reduce their global warming emission. The world is putting out more carbon dioxide into the air than ever before. The current amount is 385 parts per million (ppm), higher than ever in the past 800,000 years (Gary Braasch, 2005). Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its likely continuation. Rise in global temperature will cause sea level to rise, and is likely to increase the intensity of extreme weather events and to change the amount and pattern of rainfall.
The Enhanced Greenhouse Effect For the past ten thousand years the earth’s climate has been extremely good and beneficial to mankind. Today however , major changes are taking place. Humans beings are changing the face of the entire planet by destroying the rain forests and pumping our pollutants into the air and water. Some of these gases are very toxic and they are destroying our ozone layers which allows life to exist on earth These things are changing the make-up of the earth’s biosphere and its heat balance in a very negative way. Global Warming is an increase in the earth’s temperature due to the use of fossil fuels and other industrial processes, leading to a buildup of green house gasses.
Earth has its cooling and heating periods. But scientist fear that the heating periods are happening faster than usual to because of the manmade emissions. There are natural causes that cause climate change but the increase in emissions from man made products has increased climate change drastically than it’s usual because of our deforestation, burning of fossil fuels, and intensive farming.
"Greenhouse gases, which have built up to unnaturally high levels in the atmosphere, trap heat. They include carbon dioxide, which is emitted when fossil fuels are burned, and other gases produced by human activity"(Watson 2). These gases besides trapping heat, created a hole in our ozone layer which will continue to increase in size if the level of gases remain too high. A hole in the ozone layer means that there is no ozone to protect us within that given size of the hole. Whether the hole is big or small it does have an effect on earth which we call global warming, which in turn can have several effects on the planet.
As this carbon dioxide from burning fossil fuels enters the atmosphere, some of it is taken up by photosynthesizing plants, and the oceans absorb some. But because we are burning so much fossil fuel at such a rapid rate, we are putting carbon dioxide into the atmosphere much faster than these natural processes are taking it out. There is no longer a balance between the amount of carbon dioxide being added to the air and the amount of carbon dioxide being removed. As a result, the concentration of carbon dioxide in the air is steadily increasing. In conclusion, if we make small changes now in the way we live, we can avoid huge changes in the future.
Scientists are now concerned that the greenhouse gases are being increased by human actions to levels that could be very harmful to life on Earth. Almost all specialists agree that without drastic steps to curb greenhouse gas emissions, the average global temperature will increase 1 to 3.5 degrees Celsius during the next century because effective levels of carbon dioxide are expected to double sometime between 2050 and 2100. Many of the greenhouse gases remain in the atmosphere for a long time, and because this happens their tendency to warm the Earth persi... ... middle of paper ... ...eforestation of previously forested land that has become agriculturally useless has to be promoted. That will require conservation incentive schemes and improvement of farm yields to reduce the pressure to clear new land. This will not be nearly as expensive as coping with the costs of global warming.
Increasing populations mean a higher demand for resources which will not be here forever. Pollution begins with the emission of greenhouse gasses into the atmosphere, mostly CO2. These gasses begin to deplete the ozone layer which is the layer that is protecting the planet from the harmful sun rays. The ozone layer plays a very important role for our planet since it absorbs the majority of ultraviolet radiation that is reaching the earth from the sun. Over the years as the human population increases the ozone layer is depleting at an increasing speed.
Global warming is caused by pollution eating away at the ozone layer of the atmosphere, as well as greenhouse gases trapping heat. The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. (Riebeek 2) Many scientists believe that the effects of global warming will greatly impact the planet. Direct effect of Global Warming is increased heat on Earth then it will cause ice on poles to melt, leading to rising sea levels and land loss, because many areas will be under water. Besides that, many events of catastrophic weather will occur, such as droughts, floods, volcanic, tsunamis and earthquake.
Earth’s temperature has increased by 0.85 Degrees Celsius from the year 1880 to 2012. If this goes on, the Earth will suffer from increased natural disasters, animals unable to adapt to the weather and die out, ice caps from the poles will melt completely and eventually the Earth will become inhabitable. First of all, we need to know what and how these green house gases collaborate to cause global warming. Carbon Dioxide (CO2), Nitrous Oxide (N2O), Methane (CH4) and especially water vapor are the main gases that increases the Earth’s temperature. These gases block the heat of the Earth from escaping.
