Have you ever listened to discussions and read articles about global warming and wondered why the resource person or the writer appears so emphatic and urgent in their call for fighting it? Well that is because global warming is an urgent problem that needs immediate action and resolution before it gets worse and could spell the end of human life and civilization as we see it today.Broadly speaking, global warming is the steady increase of the atmosphere’s and ocean’s average temperature. And before you go saying ‘Big deal’ to yourself and scoff at the near-catastrophic predictions made by scientists and advocates, consider first some of the expected effects of global warming to our environment and to our very lives.One of the most pronounced effects of global warming would be glacial retreat, in which glaciers in the Arctic region may be steadily melting. This translates to elevation of sea levels all over the world, raising concerns over obliteration of small islands and even countries. Global warming is also attributed to influence precipitation, leading to the possibility of increased flooding in some parts of the world and increased drought elsewhere. What’s scary about these projected changes is the complete inability of man to counteract and prevent them once these events start happening.But then again, global warming effects are not solely manifested in the environment. Consider the effect of increased drought and flooding to food supply, and ultimately, to food consumption. Agriculture is one large sector expecting to bear the worst of the brunt of global warming, with lesser and lesser produce and crops expected to be harvested in the next decade or so. Now that is really scary, considering we all get a large portion of our food supply from farms.Weather experts are also predicting extreme weather events due to global warming, ranging from severe snowstorms to intense cyclones and hurricanes in tropical areas.The increase in the average temperature of oceans in our planet also means dwindling in the supply of our other food source. The rest of the world might not come to realize how fragile most of the sea organisms are and expected changes in temperature would bring about extinction to most of them. Carbon dioxide, the main culprit of global warming, is also expected to acidify ocean waters, leading to more extinction and disruption of the food web.It is also worth considering the impact of global warming on human health as well. With increasing surface temperature, heat waves are expected to occur more frequently, possibly endangering children and the elderly. Many pathogens proliferate much faster in warm environment. Increasing atmospheric temperature could very well mean faster proliferation of these pathogens that would cause numerous diseases and illnesses to humans. There is also expected spread of fatal tropical diseases as the world becomes warmer and warmer, placing those living in temperate regions at higher risks.The mentioned risks and dangers are but overviews of the complexity and gravity of the problem that is global warming. A lot of resources and references have been published and produced on the subject matter and it’s time people should sit up and make effort to learn more. With increasing knowledge and understanding, the fight against global warming would no longer seem to be overwhelming and insurmountable. And as cliché as it may sound, this is one fight nobody can ever win alone, so concerted efforts are certainly needed and cooperation from all sectors would be very much welcome.

There has been a lot of talk on the subject of global warming. Specialists believe that human activities in the past 50 years have given a negative boost to climate change. After a long series of tests and chart observations, it seems that the primary culprit for global warming is the emission of greenhouse gases (mainly carbon dioxide, methane and nitrous oxide). These gases have altered the composition of the atmosphere and raised the planet’s temperature with almost 1?C since 1950.
The problem is not that these gases exist. They have always been in the atmosphere, but there is a major increase in their concentration. The planet started to heat up and the climate change appeared simultaneously with the beginning of industrial revolution. Then, at the start of a new era, the concentrations of carbon dioxide increased with nearly 30%, methane almost doubled and nitrous oxide with 15% making global warming a serious, even deadly matter.
These figures are truly concerning due to the fact that we rely on fossil fuels to drive, to heat and to power factories not thinking of the harsh reality: burned fossil fuels are the main reason for the rise of carbon dioxide in the atmosphere leading to global warming and accelerating the rate of climate change.
Still, the combustion of fuel is not the only one to blame for global warming. Researchers consider that the development of agriculture, deforestation, landfills, industrial production and mining are also to blame. Each one of them has ‘helped’ induce large, global, abrupt climate change leading to a warmer planet, making it more difficult for us to live.
The statistics in climate change are frightening. Almost 98% of the greenhouses emissions are due to pollution and it is no surprise that the most powerful and rich country (U.S) on the continent is mainly responsible for global warming. 1998 has been declared the warmest year on record and scientistists are concerned that the snow cover in northern hemisphere and floating ice in the Arctic Ocean have decreased. Do we really pay enough attention to the climate change and do we want the planet to become too warm for us to live in?
We are all threathened by this sudden climate change. Global warming is not a joke and we should start paying more attention to it. Not only wildlife, forests and coastal areas are vulnerable to the climate change that the greenhouse gas may bring, but also water resources, animals and most important our health.
What should we expect from global warming? First of all, a change that will have a major impact on the way we live will be a warmer weather. Climate change will appear in the form of increased precipations worldwide, with acid rainfalls that will damage the natural habitat, with more frequent and intense storms that will build up and result in powerful hurricanes. And this is just the top of the ‘iceberg’ called global warming. The hurricanes will be stronger than usual with greater devastating powers.
The population of the globe should be taught more about these greenhouse gases that are held responsible for climate change and more specific, global warming. Carbon dioxide is realeased into the atmosphere when wood, fossil fuels (oil, gas and coal) and solid waste are burned. Methane is emitted during the production and transport of oil, gas and coal, but it also results from decomposition of solid, organic waste. Nitrous oxide is the product of: agricultural and industrial activities, combustion of fossil fuels and solid waste. So, do we still have to wonder why these greenhouse gases have such a strong impact on climate change?
Unfortunately, there are not many options to reduce the effects of global warming. Lately, in order to predict climate change, specialists have put up what is called an emission inventory which registers the quantity of air pollutants in the atmosphere. It also establishes the identity of the polluting agent (chemical/physical), the geographic area covered, the time period over which emissions are appreciated and the type of activities that cause the emissions. This way, the scientific community is making an effort to reduce the serious consequences of global warming.
Another solution for the problem of global warming is recycling. It started years ago in powerful and well developed states and it is a novelty for poor, undergoing tranzition states that are struggling to survive. But, slowly, people all over the world are learning about the strong effects of recycling newspapers, plastic, glass, metal. It is a healthy action that makes the world a better place. By recycling, we not only help ourselves, but also the forests, crop yields and water supplies which are severely affected by climate change. We also keep in mind the animals and the ecosystems – another sector badly damaged by climate change. We make the difference.
Global warming affects everybody. That is why we must fight against our self destruction and life’s in general. Fight for your planet, don’t let the climate change affect the environment in an irrecoverable manner, keep in mind that Earth’s eco systems are sensitive and must be treated with care, and you will have a future!
Knowledge about our environment, global warming and the way we influence the climate change is the key to how our world will look like in the future. You have to have the power to change things and make them better.

The legendary Indian spiritual leader Mahatma Gandhi (1869-1948) once said: “The earth has enough for the needs of all but not the greed of a few.” His words have since proved to be quite prophetic!
The world today is in chaos and by that I’m not merely referring to the tumult taking place in the Middle East; what I’m talking about is the imminent extinction of hundreds of millions of people as a result of global warming. In both scenarios the United States plays a central role!
I have already pretty much detailed out how and why global warming is happening and which nations are most responsible for its acceleration, as well as who’s doing what and who is not to rectify the situation in my article entitled: Global Warming–How It Could Spark World War III.
That said, I’ve included a list of figures below to illustrate to what extent each nation/region is responsible for greenhouse gas pollution in the atmosphere (greenhouse gases are widely held to be the engine behind the accelerated global warming seen today):
USA: 30.3% Europe: 27.7% Russia: 13.7% South East Asia: 12.2% South/Central America: 3.8% Japan: 3.7% Middle East: 2.6% Africa: 2.5% Australia: 1.1%
THE TRUTH BEHIND THE LIE
To many in marketing circles the concept of manipulation of social evidence is nothing new. Basically what it entails is manipulating tools of evidence to further one’s goals.
Thus for example, until fairly recently in internet marketing circles, the practice of manufacturing bogus testimonials was fairly widespread.
The objective being to convince visitors to one’s website to purchase products on the strength of those manufactured testimonials.
In the arena of global warming much the same has been happening. In the same manner that a defense counsel in a court case will produce its own expert witness to discredit that of the prosecution (or vice versa) so has the Bush II administration paraded a string of bogus experts to decry global warming as just a myth!
In 2007 a good number of environmental scientists and climatologists publicly stated that they’d been pressurized by various Bush II factions to manipulate data to downplay the seriousness of global warming!
Which simply begs the question: why is the Bush II administration going to such lengths to hide the truth about global warming?
SNATCH AND GRAB OPERATION GONE AWRY
It is now widely accepted that the invasion of Iraq had little to do with terrorism, less to do with democracy but everything to do with oil!
The question still remains however, why did the US go to such lengths (which included manufacturing evidence) to illegally invade a sovereign state under what at best can be described as a thinly disguised pretext for war?
Was it merely a question of the then single remaining superpower claiming its right to wield that might as it saw fit irrespective of international law, just as Nazi Germany once did?
Or was it a case of a few vain men hoping to claim their slice of immortality through a legacy festooned with the glory of having secured new oil reserves for a nation with a quenchless thirst for the stuff?
Or perhaps the U.S. oil reserves were so desperately low that Bush II and his New World Order buddies were prepared to force a snatch and grab operation that could easily have escalated into third world war, so as to shore up those dwindled oil reserves?
Or maybe, just maybe, the U.S. desperately needed to stockpile a vast amount of oil for something far, far more sinister.
To keep at bay a monster it helped so much to create!
THREADS WEAVING A DISTURBING TAPESTRY OF EVENTS
These days more often than not fact is stranger than fiction. When we look at the Bush II Administration’s policy on global warming it is beyond perplexing why they have gone to such lengths to deny its existence.
For sure, his Have-More buddies in oil and other environmental-damaging industries have plenty to gain by muddying the waters, but what if there’s really more to this repudiation of global warming than that!
What if this is a carefully concocted plot that has been kept under wraps for years?
Here’s what we know thus far about global warming. The data has been around for well over a decade and has been readily available to government officials.
Since the turn of the 21st century scientists across the globe have been warning of the extent of global warming; warnings that apparently fell on deaf ears! (Well at least as far as the Bush II administration was concerned.)
But supposing this was not actually the case.
What if the Bush II administration did listen, but only to those scientists who’d concluded that the world had reached the point of no return? And that global warming could not be reversed anytime in the foreseeable future and thus by proxy neither could its ensuing effects!
FUELING UP FOR A GLOBAL CATASTROPHE
In other words there was no point implementing measures to curb greenhouse gas emissions (thereby slowing down global warming) and that in fact the best policy was to forge powerfully ahead and ensure that America was readied for the ensuing catastrophe no matter the cost!
If it meant manufacturing a war, so be it! If it meant causing the deaths of hundreds of millions of people to achieve that aim, so be it! After all this wouldn’t be the first time in history that the few had been sacrificed for the many!
Oh! Except in this case it is the many sacrificing for the few, or more specifically, The Have-Mores!
When looked at from this perspective, that the U.S. is fuelling up for a long term global catastrophe, it all begins to make some sense! Especially considering that Saudi Arabia still has the greatest oil reserves in the world and has never said no to U.S. oil demands!
Bottom line, it is quite conceivable that the U.S. under Bush II has been insuring against (or at least trying to) a global catastrophe predominantly of its own making! But alas even the best laid plans go badly awry. Iraq didn’t turn out to be the pushover they’d expected and the oil is not gushing the way they had envisioned.
Think that such a scenario is way over the top? Think again! Remember Iraq? Remember Hurricane Katrina?
The way the Bush II government handled Katrina was so shameful that Google for some reason best known to it was compelled to replace post-Hurricane Katrina satellite imagery with pre-hurricane images on its map portal (Damage control? Trying to hide America’s shame from the rest of the world? At whose behest one wonders?).
As you can well imagine, when it came to light, the whole sordid affair was an extreme embarrassment to Google (And certainly not good for business! The search engine business thrives on the premise that results are accurate and impartial and not manipulated!).
But the point I wish to emphasize here is that if the Bush II government could shun its very own citizens (albeit mainly citizens of color) in such a cavalier fashion why would they give a damn if their actions resulted in the deaths of hundreds of millions of Africans or peoples from other parts of the globe who are going to be worst hit by global warming?
In World War II the Nazi’s genocide weapon-of-choice was hydrogen cyanide gas, what irony that in the upcoming global warming related genocide, gas too is the weapon of choice; carbon dioxide gas!

In 2008, scientists from all over the world are jumping off the man-made global warming bandwagon. This is due to the fact that environmental study after study concludes that the behavior of man is not the cause of significant global warming.In a recently released Geological Society of America abstract, Dr. Don Easterbrook, Professor of Geology at Western Washington University, presented data showing that the global warming cycle from 1977 to 1998 is now over and that we have entered into a new global cooling period that should last for the next three decades.He also suggests that since the IPCC climate models are now so far off from what is actually happening that their projections for both this decade and century must be considered highly unreliable.Meanwhile, David Douglass and John Christy, in a paper just accepted for publication and now available on the internet, have come to the conclusion that natural changes in global water temperature are responsible for an increase in global temperature. Here is their scientific conclusion:”El Nino and La Nina effects in the tropics have a more significant affect on global temperature anomalies than carbon dioxide, in particular it was an El Nino event that drove the 1998 global temperature maximum”.At NASA, Dr. Roy Spencer, believes natural cycles account for most of last century’s warming, with carbon dioxide increases contributing only a modest amount.His new research, which was submitted to Geophysical Research Letters for publication, shows that climate models overstate the positive feedback from an increase in carbon dioxide, and therefore grossly overstate the projected warming during the next centuryIn addition, two new studies (article in Science Magazine) point to wind-induced circulation changes in the ocean as the dominant cause of the recent ice losses through the glaciers draining both the Greenland and West Antarctic ice sheets, not ‘global warming.’In June, Dr. David Evans, an architect of Australia’s Kyoto compliance, and for years a noted climate change alarmist, became the latest man-made global warming doubter. Evans outlines the four main reasons why 2008 has become the year of the global warming skeptic and why he recently jumped off of the global warming bandwagon.1.The missing “greenhouse signature”, which would be a hot zone about 10 km up in the atmosphere. It’s been sought for years – hundreds of measurements using radiosondes (a sort of temperature measuring weather balloon). It would constitute the smoking gun . Hundreds of tests have returned the same answer – it’s not there. It is statistically impossible that the hundreds of tests missed the spot. The existing models on greenhouse warming do not work without this hot zone.2. “There is no evidence to support the idea that carbon emissions cause significant global warming” says Evans. “None”. There is plenty of evidence that global warming has occurred, and theory suggests that carbon emissions should raise temperatures (though by how much is hotly disputed) but there are no observations” constituting evidence that carbon emissions are a significant driver in warming trends.3. Satellites measuring the world’s temperature uniformly show that the warming trend stopped in 2001 and that in the past year the temperature actually returned to 1980 levels. Satellite measurements are the only truly reliable method for capturing the data as land-based measurements are vulnerable to encroachments of expanding cities and “urban heat island effect.”4.”The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect.”As global temperatures continue to cool and research against man-made global warming continues to pile up, as scientists abandon the man-made global warming bandwagon, one thing is becoming increasingly clear. The cause of global climate change should be based on facts and evidence and not just our fear.

Global warming is not a 20th century phenomenon. It has, in fact, occurred in the past more than once, along with periods of extreme cold known as the ice ages. With so much written and reported about global warming, sometimes it’s difficult to detect which is fact and which is just part of scientific scare tactics. Here are some facts about global warming that might help:
What exactly is global warming?
Global warming is basically the increase in the temperatures of the Earth’s atmosphere, land masses and oceans. The Earth’s surface temperature is at an average of 59F and over the last hundred years, this figure has risen to about 1F. By the year 2100, the average change in the temperature of the Earth could range from 2.5F to about 10F, enough to melt glaciers and polar ice caps.
The cause of global warming
Global warming has and will always occur naturally. Why it has become such a concern in our lifetime is due to the fact that human activities and practices have contributed significantly to its occurrence and severity. With the advent of industrialization and careless environmental practices, we have caused the increase in the average global temperatures by contributing negatively to the greenhouse effect.
This began about 240 years ago, when the Industrial Revolution was born. As more and more fossil fuels in the form of oil were mined and burned, gases as the by-product of that process began to be released in the atmosphere. Currently, it is estimated that 75% of the increase in the carbon dioxide content of the Earth’s atmosphere is caused by the burning of these fossil fuels.
Global warming and the greenhouse effect
Global warming is related to changes in the Earth’s greenhouse effect. Gases naturally occur in the Earth’s atmosphere and act both to protect and retain heat. These gases include carbon dioxide, methane, nitrous oxide and water vapor. Of these, water vapor is the most dominant and abundant greenhouse gas.
Global warming and the greenhouse effect are not the same thing. The greenhouse effect refers to a natural process that occurs in the Earth’s atmosphere. If this process is disrupted, then it could contribute to global warming.
As the sun’s rays hit the Earth, heat is bounced back to the atmosphere where these gases contain the heat and keep it there to warm the planet. This is an important natural process and allows life forms to flourish and survive. Problems only occur when these gases multiply and build-up, containing heat too efficiently and thus warming the Earth’s atmosphere.
As the Earth’s average temperature rises, effects in its landmasses and sea water level become apparent. Polar ice caps melt along with glaciers, contributing to higher and warmer sea levels. By the end of the century, it is estimated that sea levels can increase from 4 inches to a high of about 40 inches if global warming continues unabated.
Global warming can also affect the behavior of the winds and can also contribute to a harsher and drier climate, with frequent visitings of strong hurricanes. Water from heavier rainfall will not stay long to irrigate the land, however because with a warmer climate, water on the Earth’s surface will evaporate quickly. This has a significant effect on agricultural practices not only in the US but also for the rest of the world.
Another phenomenon that is equated with global warming is the El Nino. The El Nino phenomenon has occurred for possibly thousands of years and is not caused directly by global warming. However, changes in the average temperature of the planet can contribute to its severity and frequency.
Other human practices that contribute to global warming
The agricultural revolution has also contributed to global warming. As more and more communities need lands converted from forests to residential and commercial areas, biomass is reduced, contributing to the increase in the presence of carbon dioxide in those regions. Since carbon dioxide is processed by plants and trees, their absence contributes to its increase.
It is estimated that about 25% of the annual increase in the carbon dioxide found in the Earth’s atmosphere is caused by extreme changes and usage of the Earth’s natural resources. Other practices also include deforestation, salinization, desertification and overgrazing also contribute to global warming. However, many scientists surmise and agree that the contribution is slight and indirect.
Facing the facts of global warming
Countries all over the world have just begun to acknowledge the negative effects of global warming not only to the world’s politics and economy but also to humankind in general. Many of the world’s governments have encouraged implementation of measures to try to counteract the problem of global warming through careful measures and practices designed to protect and respect the environment.
How these measures will fare and contribute to the long-term maintenance of our planet, though, remains to be seen.
