The majority of the scientific community believes that global warming is a real threat to the world as we know it today. They believe that global warming mostly results from the emissions of carbon dioxide and other greenhouse gases from human activities such as industrial processes, fossil fuel combustion, and deforestation.

There are many causes of global warming. One cause is carbon dioxide that is made from the burning of fossil fuels from power plants for the purpose of electricity generation. Coal makes up 93% of these emissions. Coal emits 1.7 times more carbon per unit of energy when burned than natural gas and 1.25 times more carbon than oil. Consequently, natural gas gives off 50% less carbon dioxide for the same amount of energy produced. Another cause is carbon dioxide that is made from the burning of gasoline in internal-combustion engines of cars, minivans, sport utility vehicles, pick-up trucks, and jeeps. Poor gas mileage is considered the main culprit here. According to the Environmental Protection Agency’s 2000 Fuel Economy Guide, a new Dodge Durango sports utility vehicle (with a 5.9 liter engine) that gets 12 miles per gallon in the city will emit around 800 pounds of carbon dioxide over a distance of 500 city miles; this translates to 19.6 pounds of carbon dioxide emitted into the air for every gallon of gas a vehicle consumes.

Another cause of global warming is carbon dioxide that is made from commercial trucks, contributing another 13% of U.S. carbon dioxide emissions.

Carbon dioxide that is made from airplanes is another cause of global warming – the United Nation’s Intergovernmental Panel on Climate Change estimates that aviation causes 3.5% of global warming, with a projection that it will rise to 15% by 2050.

Another cause of climate warming is carbon dioxide that is emitted by the structure of buildings, accounting for another 12% of carbon dioxide emissions.

Methane is another cause of climate warming, as methane is the second most important greenhouse gas after carbon dioxide. According to the IPCC, methane is 20 times more effective than CO2 in trapping heat in the atmosphere. US Emissions Inventory 2004 levels of atmospheric methane have risen 145% in the last 100 years. Sources of this rise in methane include rice paddies, bovine flatulence, bacteria in bogs, and fossil fuel production.

Another cause of global warming is nitrous oxide, a colourless, non-flammable gas with a sweetish odour. It is naturally produced by oceans and rainforests, while it is also artificially produced in nylon, nitric acid production, agricultural fertilizers, cars with catalytic converters, and burning organic matter.

Deforestation is also one of the causes of global warming, the second-leading cause only to carbon emissions. Deforestation is responsible for 25% of all carbon emissions entering the atmosphere, as 34 million acres of trees are burn and cut each year. The destroying of tropical forests alone emit hundreds of millions of tons of carbon dioxide into the atmosphere each year.

City gridlock is another global warming cause. According to an annual study by traffic engineers from Texas A&M University, drivers in Los Angeles and New York alone waste 600 million gallons of gas annually while just sitting in traffic. That translates into around 7.5 million tons of carbon dioxide that is emitted into the atmosphere. And remember, just two major U.S. cities are named, not to mention the rest of the U.S. and the world.

Another global warming cause is just the amount of carbon already in the Earth’s atmosphere naturally, as 750 billion tons of carbon are present. Add in another 800 billion tons of carbon that is dissolved in the surface layers of the world’s oceans.

As you can see, carbon dioxide, methane, and nitrous oxide are the major causes of global warming. You can also see there are many sources of these gases, especially carbon dioxide. Much work needs to be done in order to address all the causes of global warming.

These days, there seems to be a lot of controversy about Global Warming.

Some say that Global Warming is a fact, others say it’s not. But regardless of whether or not Global Warming is a fact, let’s step aside from the arguments on the subject, and take a common-sense approach.

In this article we will take a look at some of the issues involved.

What is Global Warming?

We can take a look at the definition of global warming – without taking sides or getting into vested interests, political motivations, reasons, or causes.

The definition of global warming in its purity is “an overall increase in world temperatures.” As you can see, whether this has to do with greenhouse emissions, or whether it is caused by a natural phenomena, has no bearing on whether there is an average temperature increase.

Is There an Overall Increase in World Temperatures?

Alright, now we can take a look at what scientists say about world temperatures.

Again, we are going to leave out the reasons why, and simply look at whether or not the Earth’s general temperature is rising.

According to NASA scientists, the average temperature of the earth rose by one degree Celsius, over the last century. This is based on actual measurements taken with exact measuring instruments.

Another report, compiled and submitted by 600 scientists from the Intergovernmental Panel on Climate Change, issued the following statement:

“Warming of the climate system is unequivocal.”

These 600 scientists sifted through thousands of studies and reports, in order to come to the above conclusion.

Even scientists who are “opposed” to the global warming theory are not contradicting the fact that the earth’s temperature is rising. These scientists are only saying that global warming is a natural phenomena, and is not caused by man.

The Causes of Global Warming There are several factors that could contribute to or influence global warming.

Greenhouse gases are gases that prevent heat from escaping from the Earth’s atmosphere. A few examples of greenhouse gases are:

As you can see, carbon dioxide, methane, and nitrous oxide are produced mainly by human resources, whereas chlorofluorocarbons are exclusively produced by industrial installations.

Out of all the above, interestingly enough, the greenhouse gases which have the largest effect on global warming are water vapors. This fact will no doubt please all critics of the “global warming theory”.

You have to keep in mind, however, the cyclic effect of global warming. A slight increase in temperature will increase the amount of water vapor in the atmosphere, which in turn will increase the temperature, and so on. Thus, a slight effect created by other greenhouse gases has a much larger impact, due to the creation of additional water vapor in the atmosphere.

Greenhouse Gases: Facts and Figures

let’s go over some facts and figures here. Again, keep in mind that these are measurements taken by scientific tools. They are not statements for or against global warming.

The Effects of Global Warming

I am not the doom-and-gloom sort of person, so I am going to spare you the details here. But I do have an opinion on this subject, so I will share it with you.

Regardless of whether the globe is warming or not, it is simply common sense to take care of the environment you live in.

The plain truth of the matter is that carbon monoxide is unhealthy, methane makes for unpleasant breathing, and nitrous oxide in the atmosphere is no laughing matter.

While the lack of ozone might make for faster tanning at the beach, the long term effects are not as desirable.

What You Can do About Global Warming

Believe it or not, you are important – what you do and say is listened to by others, and does make a difference. It doesn’t require a lot of effort to do something about conditions in the environment. A little extra care will go quite a long way. Many are already doing it, and all of us need to get aboard.

It starts as simply as recycling your waste, saving energy where you can, or even planting a tree.

Global Warming – Information and Tips regarding Global Warming

Definition of Global Warming:

Global Warming is the increase in the average measured temperature of the Earth’s near-surface air and oceans since the mid-20th century, and its projected continuation.

Average measured temperature is the instrumental temperature record shows the fluctuations of the temperature of the atmosphere and the oceans as measured by temperature sensors. Currently, the longest-running temperature record is the Central England temperature data series that starts in 1659. The longest-running quasi-global record starts in 1850.

IPCC:

The Intergovernmental Panel on Climate Change (IPCC) concludes “most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations via an enhanced greenhouse effect.

These basic conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. While individual scientists have voiced disagreement with these findings, the overwhelming majority of scientists working on climate change agree with the IPCC’s main conclusions.

Effects of Global Warming:

According to projections made by the IPCC, the average global surface temperature will rise a further 6 degrees Celsius during this century. Although most of the studies and predictions are made up to a certain century, warmer temperatures and the rise of the sea level are expected to continue for more than a 1000 years even if greenhouse gas levels are brought down.”

Some of the effects of Global Warming include:

1.      Increase global temperature and that causes sea levels to rise.

2.      Increase in the intensity of extreme weather events decreasing tropical areas and increasing the amount of deserted places.

3.      Agricultural cycles changes.

4.      Mass species extinctions.

5.      Increase of disease spreading.

Some of the uncertainties are the amount of warming that will take place in the future and how it will differ from region to region around the world.

Governments are trying to make a difference and most of the national governments have signed the Kyoto Protocol. The Kyoto Protocol is a protocol to the International Framework Convention on Climate Change and it is aimed at reducing greenhouse gas emissions.

So as you can see, Global Warming is happening and is happening now. It seems that the future of our children looks dull, but we as parents, leaders and decision makers can still make a difference. We need to change our thinking and our daily habits. This is not an easy thing to do, but we can and must do it. There is lots of information and tips that we can use in our daily life to live a greener live. There are even products we can buy to implement in our lives that can help saving energy and be more environment friendly.

I used to joke that the government issues so much information every day, it can’t help but let the truth slip out every once in a while. The Bush Administration’s recent report on global warming is a classic example. Though far from perfect, it contains some crucial but awkward truths that neither George W. Bush nor his environmentalist critics want to confront. Which may explain why the Administration has sought to bury the report, while critics have misrepresented its most ominous conclusion.

The US Climate Action Report made headlines because it contradicted so much of what the Administration has said about global warming. Not only is global warming real, according to the report, but its consequences – heat waves, water shortages, rising sea levels, loss of beaches and marshes, more frequent and violent weather – will be punishing for Americans.

The report’s biggest surprise was its admission that human activities, especially the burning of oil and other fossil fuels, are the primary cause of climate change. Of course, the rest of the world has known since 1995 that human actions have “a discernible impact” on the global climate, to quote a landmark report by the United Nations Intergovernmental Panel on Climate Change. But the White House has resisted this conclusion. After all, if burning fossil fuels is to blame for global warming, it makes sense to burn less of them.

To a lifelong oilman like Bush, who continues to rely on his former industry colleagues for campaign contributions as well as senior staff, such a view is nothing less than heresy. No wonder, then, that Bush and his high command have virtually repudiated the report. Although their staffs helped write it, both EPA Administrators claimed they were unaware of the report until the New York Times disclosed its existence on June 3. Bush himself dismissed it as a mere product of “the bureaucracy,” that oft-vilified boogeyman of right-wing ideology.

But he could equally have blamed his own father. The only reason U.S. Climate Action Report 2002 was compiled in the first place is that George Bush the First signed a global warming treaty at the 1992 Earth Summit that obligates the United States to periodically furnish such reports to the UN (one more reason, it seems, to despise treaties). But somebody in the Administration must have seen trouble coming, because the report could not have been released with less fanfare: It was simply posted on the EPA’s website, three unguided links in from the homepage. If you weren’t looking for it, you’d never find it.

The Administration has been hammered for issuing a report that on one hand admits that global warming threatens catastrophe but on the other maintains there is no need to reduce consumption of fossil fuels. The report squares this circle by arguing that global warming has now become inevitable, so we should focus less on preventing it than on adapting to it. To deal with water scarcity, for example, the report advocates building more dams and raising the price of water to encourage conservation. Critics see such recommendations as proof that the Administration is doing nothing about global warming. Unfortunately, it’s not that simple.

The worst thing about the new global warming report is that it is absolutely correct about a fundamental but often unmentioned aspect of the problem: the lag effect. Most greenhouse gases remain in the atmosphere for approximately 100 years. The upshot of this undeniable chemical fact is that no matter what remedial steps are taken today, humanity is doomed to experience however much global warming the past 100 years of human activities will generate.

That does not mean we should make matters worse by continuing to burn fossil fuels, as Bush foolishly urges; our children and grandchildren deserve better than that. It does mean, however, that we as a civilization must not only shift to green energy sources immediately but also begin planning how we will adapt to a world that is bound to be a hotter, drier, more disaster-punctuated place in the twenty-first century.

Many environmentalists know it is too late to prevent global warming; the best we can do is minimize its scope. They don’t like to admit this truth, because they fear it will discourage people from making, and demanding, the personal and institutional changes needed to reduce greenhouse gas emissions. There is that risk. But a truth does not disappear simply because it is inconvenient. Besides, a green energy future would mean more, not less, economic well-being for most Americans, while also increasing our chances of avoiding the most extreme global warming scenarios. Sometimes the truth hurts. But avoiding it will hurt even more.

The problem with the true believer is that an issue becomes black and white. There is no room for discussion. The true believer is right and if you do not agree with him/her, you are dead wrong. The fact is the true believer is not satisfied just with the knowledge that they are right. They need you to acknowledge that they are right as well. They need to convert you. There can be no dissension. There can be no discourse. Facts do not really matter if they do not fit into the true believer’s argument.

In extreme and violent terms we have seen this behavior manifest itself throughout history. The Crusades and the misguided horrors of Nazi Germany in the Second World War are examples. Today the violent true believer mentality can be seen in the extreme elements of Islam.The true believer mentality also exists in less dramatic and more subtle ways throughout our society. It can be seen in ethnic, racial or gender discrimination. It can be seen in religious intolerance. Unfortunately, it was also be seen in the United Nations sponsored climate change event in Bali in December 2007.

The U.N. Intergovernmental Panel on Climate Change (IPCC) panel’s chairman, Rajendra Pachauri, said: Climate change imperils “the most precious treasures of our planet,” and the effects are “so severe and so sweeping that only urgent global action will do.

In fact, the United Nations reports that global warming is “unequivocal”. It estimates that as early as the year 2020 between 75 and 250 million people in Africa will suffer water shortages. It goes on to state that residents of Asia’s largest cities will be at great risk of river and coastal flooding. Europeans can expect extensive species loss. North Americans will experience longer and hotter heat waves and greater competition for water.

The world’s scientists have spoken clearly and with one voice,” UN Secretary-General Ban Ki-moon said, “I expect the world’s policy makers to do the same.”

According to the United Nations true believers, global warming is “unequivocal” and the world scientists “have spoken clearly and with one voice”. There is no discussion. There is no dissent. All knowledgeable people now have been converted to this crusade. The reality, of course, is that global warming consensus is not the case in the scientific community.

Indeed for the Nobel winning United Nations panel (IPCC) and Nobel Prize winner Al Gore, fundamental problems with their global warming argument have already started to appear. As true believers in their global warming crusade, they will probably rationalize or ignore all facts that do not advance the cause. For the rest of us, as objective observers of the issue of global warming, the following facts should be carefully considered.

Global warming was supposed to cause frequent and violent hurricanes. The fact is that neither the intensity nor the frequency of hurricanes has increased. The 2007 season was the third quietest since 1966. In 2006 not a single hurricane made landfall in the U.S..

Since the mid 19th century, the mean global temperature has increased by 0.7 degrees Celsius. This slight warming is not unusual, and lies well within the range of natural variation. Carbon dioxide continues to increase in the atmosphere, but the mean planetary temperature hasn’t increased significantly now for the last nine years.

In fact , 2007 provides anecdotal evidence that the Earth is, in effect, cooling. Antarctica is getting colder. Snow fell for the first time in Buenos Aires since 1918. Australia had the coldest June in its history this year. It snowed in South Africa for the first time in 15 years. South America experienced one of its coldest winters in the last three decades.

The truth is that the entire southern hemisphere experienced bitter cold weather in 2007. In addition, the Canadian government has just warned that this winter is likely to be its coldest in at least 15 years. Already, this winter has been very cold in many other parts of the Northern Hemisphere as well.

We have heard about global warming causing the rapidly melting Arctic Ice Cap in the last several years. In fact, advocates of man made global warming point to the rapidly melting Arctic ice as a sign that global warming is occurring even faster than expected.

However, the facts as reported by NASA’s Jet Propulsion Laboratory in California last month indicate a quite different conclusion. The melting of the Arctic sea ice in this study has nothing to do with global warming. It was a natural phenomenon caused by unusual winds and atmospheric pressure.

The project studied trends in Arctic Sea Ice using satellite data , computer models and buoy observations of sea ice drift. The conclusion of the study was as follows: “The rapid decline in winter perennial ice the past two years was caused by unusual winds. Unusual atmospheric conditions set up wind patterns that compressed the sea ice, loaded it into the Transpolar Drift Stream, and then sped its flow out of the Arctic. When that sea ice reached lower latitudes, it rapidly melted in the warmer waters. The winds causing this trend in ice reduction were set up by an unusual pattern of atmospheric pressure that began at the beginning of this century”.

Global warming proponents have pointed out that records showed that 1998 was the hottest year on record in the United States. Several of the years surrounding 1998 were very warm and near the record as well. It certainly appeared that the climate was warming due to these historical records. However, it has just been discovered that the records were erroneous. A Canadian blogger named Steve McIntyre audited the NASA records and found errors. When he reported his findings to NASA scientists, they conducted a review that showed he was correct.

This led NASA to recently revise the data published on its website. The errors change the historical facts concerning the global warming argument. The hottest year in the United States is no longer 1998, but 1934. 2001 is no longer in the Top Ten. Instead, four of the top ten hottest years are in the 1930s.

Global warming is an issue that needs to be looked at objectively. It is an issue for rational discourse concerning science and facts. However, it has become a crusade for environmental true believers. Despite the United Nations rhetoric, scientists do not speak with “one voice” and man-made global warming is not “unequivocal”.

The danger in blindly following the United Nations global warming crusaders is that we become far removed from the facts of the issue. Indeed, these same United Nations true believers could one day be wearing winter coats in tropical Bali asking Gaia, (the goddess of nature), for increased global warming. Such perversity happens when an issue becomes a crusade.

In February 2007, the Intergovernmental Panel on Climate Change (IPCC) stated in their Fourth Assessment Report that human actions are “very likely” (i.e. with 90% or greater probability) the cause of global warming, indicated by an increase of 0.75 degrees in average global temperatures over the last 100 years. This statement is the result of very tough discussions on a worldwide scale between thousands of climate researchers whether human activity is the main cause of global warming. The results of this discussion were presented to the public in many publications, for instance in Martin Durkin´s documentary “The Great Global Warming Swindle”, presented in March 2007 at UK´s Channel 4. The main message of this production was that man-made global warming is “a lie” and “the biggest scam of modern times.” Martin Durkin and coworkers argue that the scientific consensus on climate change is the product of “a multibillion-dollar worldwide industry, created by fanatically anti-industrial environmentalists, supported by scientists peddling scare stories to chase funding and propped up by complicit politicians and the media”. The documentary showcases scientists, politicians, economists, writers, and others who are sceptical of the scientific consensus on anthropogenic (or man-made) global warming. Some of the scientists, opposing the main stream of greenhouse gas theories, simply argue that it has not yet been ascertained whether humans are the primary cause of global warming or if there are other natural variations responsible for this phenomenon like increased solar activity, cosmic rays or variations in natural climatic cycles. There is also a series of scientists questioning the temperature records used in the databases as temperature differences attributed to the greenhouse effect are reasonable small (fractions of a ºC). The so-called “urban heat island” effect leads to a local warming in more populated areas, showing slightly higher temperatures due to to increased heat generated by cities, rather than a global temperature rise. Anyhow, this argument was confuted by the IPPC, indicating that the effect of the urban heat island on the global temperature trend is no more than 0.05 °C (0.09 °F) degrees through 1990.

Other facts presented by the film were shown to be incorrect or misinterpreted. The film asserts for instance that records of atmospheric CO2 levels since 1940 show a continuing increase, but during this period, global temperature decreased until 1975, and has increased since then. Anyhow, it is well recognized that this cooling was driven mostly by aerosols (i.e. pollution) in the atmosphere. There is nothing contradictory about this cooling when all sources of radiation changes are considered. A second argument that easily can be invalidated is the impact of the so-called “solar variation theory” on global warming. According to the authors, solar activity (and involving cosmic rays as well as heat from the sun aiding cloud formation) is currently at an extremely high level and directly linked to changes in global temperature. The film argues that solar activity is far more influential on global warming than any other anthropogenic or natural activity on Earth. What the film does not mention is that solar activity has declined over the last 30 years – at the same time as the major spike in global temperature.

But there are some statements related to the influence of the oceanic mass and water vapour on climate change which are more difficult to confute. Water vapour makes up about 98% of the greenhouse gases by volume and provides something between 40 to 80 percent of the natural greenhouse effect. It probably has the largest impact on the planet’s temperature and climatic conditions, much larger than CO2. Water particles in the form of clouds act to reflect incoming solar heat, but the film argues that the effects of clouds cannot be accurately simulated by scientists attempting to predict future weather patterns and their effects on global warming. This argument probably is correct and it is well recognized that water vapor is responsible for the natural warming up of the surface temperature to approximately 30-35ºC. Anthropogenic greenhouse effect, according to the film’s argumentation, is only about 2% of the total “natural” greenhouse effect, which corresponds to a 0.6-0.7 ºC increase in temperature. This estimate is somewhat smaller compared to the results of much more sophisticated simulations (0.9 – 2.7ºC), but there is undoubtedly an anthropogenic effect of CO2 increasing the average surface temperature.

One example of the complexity of climatic simulations is the prediction of future storm events considering global warming effects. According to a recently published study, published online by research meteorologist Tom Knutson in the journal Nature Geoscience and resumed in the New York Times (May 18, 2008), global warming isn’t to blame for the recent jump in hurricanes in the Atlantic. The study predicts that by the end of the century the number of hurricanes in the Atlantic will fall by 18 percent. In the past, Knutson has raised concerns about the effects of climate change on storms. His new paper has the potential to heat up a simmering debate among meteorologists about current and future effects of global warming in the Atlantic. And Knutson is not alone with this view. Another group of experts, those who study hurricanes and who are more often skeptical about global warming, also say there is no link between global warming and hurricane frequency. They attribute the recent increase to a natural multi-decade cycle. According to the prediction, the number of hurricanes touching land in the US and its neighbors will drop by about 30 percent because of wind factors. However, the biggest storms, those with winds of more than 110 mph, would only decrease in frequency by 8 percent. The biggest decrease is forecasted for storms with winds between 39 and 73 mph (normal tropical storms), who would decrease by 27 percent.

It’s not all good news from Knutson’s study, however. His computer model also forecasts that “hurricanes and tropical storms will be wetter and fiercer. Rainfall within 30 miles of a hurricane should jump by 37 percent and wind strength should increase by about 2 percent”, Knutson’s study says.

There are already critical reactions on this new publication. MIT hurricane meteorologist Kerry Emanuel claims that the computer model used by Knutson is not adequate enough to look at storms and according to Kevin Trenberth, a climate scientist from the National Center for Atmospheric Research in Boulder, Colo., Knutson’s computer model is poor at assessing tropical weather and ”fail to replicate storms with any kind of fidelity.” It also does not considering well enough the intensity, duration and size of the storm events, as not only the number of hurricanes is important to evaluate.

Positive feedback comes from NOAA hurricane meteorologist Chris Landsea , who wasn’t part of this study, praised Knutson’s work as ”very consistent with what’s being said all along.” ”I think global warming is a big concern, but when it comes to hurricanes the evidence for changes is pretty darn tiny,” Landsea said.
