Since the late 1960s, but more prominently in the last twenty years we have all heard of the phrase ‘global warming.’ Generally most people by now have an idea that this has something to do with the planets temperature, but, that it’s cause’s and effects are often hard to identify and quantify.

Global warming is a natural occurrence, think of planet Earth as a very, very complex machine, it has many intricate systems which allow it to sustain life, and global warming is simply one of  those systems, whereby ‘greenhouse gases’ as they have become known, trap solar heat in the Earth’s atmosphere. Greenhouse gases can be natural, such as water vapour, but the levels of others such as carbon dioxide (CO2) are not always so natural. By trapping solar heat greenhouse gases affect the Earth’s temperature and keep the planet from getting too cold (alternatively we might experience global cooling). In this respect it is a vital, natural event that makes our planet habitable, but the fear is that it is a process which has been affected by human behaviour which could have serious repercussions.

Perhaps the most important and controversial question is, to what extent has human activity increased or speeded up the process of global warming, and how? It has been argued that since the  industrial age, the burning of naturally found fossil fuels such as coal and oil has increased the amount of carbon dioxide that has been released into the Earth’s atmosphere, and that this has speeded up global warming. Further more as the world’s population increases, so has our need for energy, meaning the problem increases year on year, especially, when considering the additional pollution from emerging countries such as China.

Public opinion seems to be mixed generally on this subject, varying from people who adamantly don’t believe or care, to people who devote their life to creating awareness. Even governments’ aren’t entirely convinced, or are at least, slow to act. The previous American administration, under President George W Bush, toed an almost non-committal line based on G8 recommendations to halve carbon dioxide emissions by 2050, and seemed impartial when faced with the issue of the human impact on global warming. This may largely have been to do with national policy, but there is also a hint that it is based on personal belief as well as financial interests (The US had a preferred policy of burning home coal reserves as opposed to using cleaner gas energy). Factor into this that China refused to reduce it’s own carbon footprint until America did so and sometimes the situation seems deadlocked (but please read further).

This is ironic considering that after losing the 2000 American Election, Mr Bush’s opposition leader, former Vice President Al Gore presented in a film about the same issue, An Inconvenient Truth  (David Guggenheim, 2006), details exactly how man’s behaviour is having an effect on the environment. Reiterating that the burning of fossil fuels, air travel, car use and the depletion of green / forest land has increased the amount of carbon dioxide (and other man made greenhouse gases) that accumulates in the atmosphere. 

The issue is so important that in 1988 the Intergovernmental Panel on Climate Change (IPCC) was set up. The aim of the IPCC is to offer an objective source of information about the causes of climate change, its potential environmental and socio-economic consequences. It comprises of many scientists writing papers to outline those causes and effects that they believe are man-made or being sped up by human behaviour.

And, as previously mentioned it’s not new news, as early as 1968, Paul R. Ehrlich commented in his book The Population Bomb that: the greenhouse effect is being enhanced now by the greatly increased level of carbon dioxide, that [a]t the moment we cannot predict what the overall climatic results will be of our using the atmosphere as a garbage dump.

So what has taken us so long? Because over 40 years later we can see what the effects of using our atmosphere as a garbage dump, are. Our polar ice caps are melting. Vast areas of American landscape’s are changing, such as in Patagonia where glaciers are disappearing. If shelf ice in Greenland melts, sea levels could raise by as much as 20 foot, reducing land mass across the planet (not to mention the amount of extra trapped greenhouses gases they will release on breaking up). The ice is also fresh water which will affect the salinity in the water affecting natural sea life. Greenpeace also states that based on our current behaviour and negligence, within 50 years one third of all land based animals will face extinction. And, as  natural disasters increase, such as hurricanes (Katrina), droughts, floods, its not hard to see that already it is having an impact on human life, with around 150,000 people dying every year as a direct result of global warming.

In summary, whether you believe in man’s affect on global warming or not, we as humans need to take more responsibility for the care taking of our planet. I’ve personally known people who regard the whole thing as rubbish, and that’s their belief (in my opinion they are dangerously wrong), but understanding two basic things must / should still prompt people to action, which is; that no country can afford not to recycle, and, sooner or later we WILL run out of fossil fuels, the burning of which are a proven link to increased greenhouse gases in the atmosphere.

The two easiest things that we can do to alleviate this problem on an individual level is try to recycle as much as possible and reduce our energy usage. Think carefully about the products you buy, do they come in recycled packaging (indeed is half the packaging required), can you get your energy from cleaner providers? Should you invest in a greener car, or failing that use public transport more often, remember to switch off appliances when not in use, use energy efficient light bulbs. Everything that we do, can done be in a greener way. As the world is a complex living machine, see yourself as a part of the whole. As the study aid for  An Inconvenient Truth suggests ‘Think globally, act locally.’ Your actions will have an impact on your local, and then, the world  wide environment. Although we seriously are threatened by what has been labelled by the Prince of Wales as, ‘mankind’s greatest challenge,’ we still have time to make a difference.

Each year the United States spends over 20 million dollars buying fossil fuels. This country emits one fourth of the world’s greenhouse gases; the most prominent of these gases is carbon dioxide, which is released from the burning of fossil fuels. Global warming has been a global issue for many years now. Some countries and people claim to be only vaguely concerned with the cause because they were unaware or uninformed of the issue. Roger Revelle, an oceanographer, helped to call out the problem to the public. After not receiving much feedback towards his cause, he criticized different governments in a jocular manner. He called warming “the great geophysical experiment.” He said, “The experiment is to load the atmosphere with as much carbon dioxide as possible, add a few other harmful gases, and see what happens.” Recently, several countries have been passing laws to prevent the world’s overheated destiny. Even with the setting of new rules and regulations, the earth continues to warm each year. Minimal efforts made to reduce the release of greenhouse gases, specifically carbon dioxide from the burning of fossil fuels, increase the rate and intensity of global warming.

The most prominent effect of global warming exists in the climate change over the past years. Many people are unaware that global warming causes and changes all types of weather. The heating of the earth causes the magnitude and strength of weather conditions to increase. As the oceans get warmer, the intensity of hurricanes amplifies in power and devastation. In addition, many coastal cities and regions have recently been experiencing flooding, caused by the melting of the polar icecaps. The Arctic’s perennial icecaps decline in area by nine percent each year. In the past thirty years, over ten national records were set for the highest temperatures in the summer and winter. Droughts and forest fires have been occurring dramatically more often in the past century. All of these effects have been directly linked to the release of greenhouse gases.

Another area affected by global warming is the animal kingdom and nature. The number of animals per specie has been decreasing annually due to harsh environmental changes. As the polar icecaps melt, all creatures that live there are left without shelter. For example, as seal dens have been melting, the number of seals has dropped. Events that occur in the spring, such as mating, migrating, laying eggs, and returning from hibernation have been taking place approximately 5.1 days earlier than they were fifty years ago. The early occurrence of these events proves that the earth is getting warmer each year. More proof of warming is the evidence of many animals traveling farther from the equator as they migrate. Although this change has been occurring with various creatures, butterflies and mosquitoes are being found the farthest from their natural habitats. Even though butterflies do not cause any known problems with the environment, mosquitoes are carries of malaria. This deadly disease has dangerously spread to new regions across the globe. If the world continues to warm, this issue, along with many others, will continue to grow.

A third type of evidence of global warming can be found in plants. Vegetation in an area differs concurrently with the climate of that same area. Throughout many parts of the world, flowers bloom 7 days earlier and trees reproduce 10 days earlier, both since 1900. As the growing seasons vary from very wet to very dry, agricultural growth cannot adapt. In some recent years, regions’ crops have been both flooded and dried out. Due to the depletion of the ozone, many crops cannot survive. Another problem is the movement and increase of allergens. Carbon in the atmosphere allows plants to go through photosynthesis more rapidly, allowing allergens to grow in number. This evidence found throughout all of nature makes it very clear that global warming is a huge issue.

A combination of various actions and, in some cases, not enough action causes global warming in the world today. The leading cause of global warming is the ongoing burning of fossil fuels, which releases carbon dioxide into the atmosphere. Carbon dioxide, along with the other greenhouse gases of methane, nitrous oxide, and chlorofluocarbons, is the cause of the greenhouse effect. This effect is dangerously increasing as the gases are being released in greater quantities. These gases not only build up to keep heat in the atmosphere, but they also thin the ozone layer. Some areas have been so thinned by the gases that there are holes present in the ozone. These dangerous holes allow harmful UV rays from the sun to reach the earth. UV rays are the main cause of skin cancer. As the earth continues to increase its pollution level each year, the number of skin cancer patients increases.

Because it releases carbon dioxide into the air, the burning of fossil fuels is an environmentally harmful practice. Carbon dioxide can be absorbed by seawater. If the water is cold, it can hold more gas. Unfortunately, with global warming, the temperature of the oceans has been increasing. As the temperatures increase, more carbon dioxide is released. This vicious circle will continue to occur unless scientists cannot this from occurring. Particularly, petrol, or gasoline, is a leading source of the release of these carbon dioxide compounds. Petrol contains hydrocarbons that release carbon dioxide when they are burned. This reaction is unfortunately unavoidable. The only solution is a different fuel source. Carbon dioxide, once released, lasts up to 100 years in the atmosphere. It is the most abundant heat-absorbent gas besides water vapor, which is not considered as a greenhouse gas because it rains back to the earth in a continuous cycle. The Mauna Loa Observatory has been measuring the level of carbon dioxide daily since 1958. Since their research began, the level in the atmosphere has drastically increased by 47 parts per million. Carbon dioxide makes up about one-half of the causes of global warming.

Although carbon dioxide largely harms the environment, the other greenhouse gases have a large impact in the atmosphere. Methane, the next most prominent harmful gas, comes from cattle, asphalt, coal, oil, and rice fields. Lasting only ten years, methane absorbs thirty times more heat than carbon dioxide. Another greenhouse gas, nitrous oxide, lasts approximately 180 years and absorbs 200 times more heat than carbon dioxide. Nitrous oxide comes from microbes in soil that are found in fertilizers. Slash-and-burn farming and the burning of some fossil fuels also emit nitrous oxide. The final greenhouse gas, chlorofluocarbon, lasts 400 years in the air and retains 16, 000 times more heat. Chlorofluocarbons escape from various cooling systems. The combination of these four gases results in the retention of intense amounts of heat.

Throughout the world, various nations have been joining to help prevent or slow the process of global warming. On February 3, 2007, French president, Jacques Chirac, proposed a new plan to prevent global warming. He stated, “It’s our responsibility. The future of humanity demands it.” Forty-five nations, not including the United States, joined him in his efforts. Al Gore, however, is very involved with global warming and the greenhouse effect; he supports Chirac and plans to help. As it is the largest contributor to global warming, the United States unfortunately supports only voluntary reduction programs.

The issue of global warming affects nature, people, and the economy. To some people, global warming is not of their concern because they feel it does not affect them. Although they may not realize it, global warming affects everyone, especially the future generations. Scientists mathematically simulate the globe’s weather systems. Their complex equations, called general circulation models (GCMs), are so complex and involve countless elements that they can take days to solve. Environmentalists verify that the hazardous combination of flooding and drought will significantly increase within the next century. The standard sea level has been rising annually for a while now. Some say that if the earth continues on the path it is on, then 95% of the Great Barrier Reef will disappear by 2075. They calculate that the glaciers in Glacier National Park could melt by 2030, and 37% of all species could be extinct by 2050.

Scientists directly link disease to global warming. Exposure to various climate or animal related diseases will increase in number and possibly brutality. Experts agree that skin cancer’s rapid rate of increase could be caused by the holes in the ozone layer. As these holes grow in size and number, the quantity of patients will also increase. Aside from natural and heath issues, the world’s economy is also at risk. Ross Gelbspan, author of Boiling Point, a book about Earth’s climate change from global warming, spoke about his book to the public in 2004 stating, “Climate issues will eventually tear holes in the global economy.” Research can show that if current weather patterns continue, the cost of insurance will increase drastically over the next few years. Gelbspan is one of many authors and scientists who look into the future to warn people what is to come; unfortunately, most people do not listen.

When people are trying to get others involved in the cause, a common problem that arises is the lack of motivation. Many people do not realize that if they can slow the rapid warming process, then there will be more time to develop alternate energy sources, such as nuclear fusion. Holland and Germany, along with several small countries, have recognized this possibility and have committed to an 80% reduction of all greenhouse gas emissions. If the United States would get involved in a program such as this, then the greenhouse effect would occur much slower than it does today. The world, especially America, needs to take action now. Stephen H. Schneider of the National Center of Atmospheric Research (NCRA) once stated, “By the time we find the greenhouse warming had damaged earth’s ability to feed its people, it will be too late to do much about it.”

In conclusion, the world needs to put forth a stronger effort to prevent global warming; the greenhouse gasses suffocate the earth more each day. If countries make a greater effort to slow global warming, the world’s predestination may not be reached until many years later. Individually, people can recycle, use fuel-efficient cars, carpool, and simply raise awareness. As said by Elmer Robinson, the director of Mauna Loa Observatory had once said while speaking of global warming, “The true enemy is us.”
