Global warming caused by humans is a myth.  It has been debunked by scientist after scientist.  The reason the earth is in a "warming cycle" (the temp on earth has risen 1 degree in the last 100 years..1 DEGREE) is because the sun is hotter.  \n\nThe environment is the new "religion" of the left, both in America and abroad. They don't believe in God and hate America.

Its not really important.\n\nThey're saying that someday the earth could heat up enough to melt the north and south poles and burry us all in water.  The sea is currently rising at a rate of like a half inch each year.  However, climet changes all of the time and so the greenhouse effect isn't necessarily a concern.

Read Michael Crichton's State of Fear. From my various reading I have learned that the earth was warmer in 1300 A.D. long before cars and it was one of the most prosperous times in history. This was before the Black Plague, of course. More land was arable and human and animal populations were flourishing. It is really impossible to tell as the Earth is in the middle of a natural warming period right now. The tree huggers will never tell you about the glaciers in Iceland that are getting bigger and the parts of Antarctica where the ice sheet is getting thicker. I am a liberal, I am for nurturing the environment. I believe common sense dictates that vehicle emissions are bad for the earth in making our air more noxious, but to answer your specific question, nobody knows because there are too many factors.

What About Global Warming . . . . \n\nThe greenhouse effect refers to the fact that Earth is surrounded by an atmosphere which acts like the transparent cover of a greenhouse, allowing sunlight to filter through while trapping heat.\n\nGreenhouse gases are trace gases of mainly water vapor, carbon dioxide, methane, ozone, and nitrous oxide. The Earth's atmosphere largely consists of nitrogen and oxygen, but these gases do not hold heat so they are not greenhouse gases nor contribute to the greenhouse effect.\n\nDuring the day the Earth absorbs heat from the Sun and re-radiates it back out to space. Normally this heat would escape each night and the temperature would fall rapidly. Instead, gaseous molecules absorb the heat given off by the planet, and re-radiate it out in all directions, reabsorbing it, and redistributing it again and again. This keeps the Earth's surface relatively warm and the average temperature comfortable. The greenhouse effect is key in Earth's ability to stay warm and sustain life.\n\nA look to our neighboring planets of Venus and Mars shows what happens when the greenhouse effect - which is akin to a blanket covering the planet - becomes too thick or too thin. Temperatures on Venus soar because of its very thick blanket or atmosphere. The runaway greenhouse effect here is staggering. Mars on the other hand has such a thin blanket (atmosphere) and a weak greenhouse effect, that the planet is very cold. Nearly all of the heat that reaches Mars escapes. Relative distance from the Sun plays a part in the global temperatures of the inner planets, but a greenhouse effect, or lack thereof, is largely responsible for the climates on all these planets.\n\nScientists started using the term "greenhouse effect" in the 1800's. At that time it had no negative connotation. In the mid 1950's the term "greenhouse effect" began to be associated with global warming and also with the negative effects of our industrial age. This enhanced greenhouse effect, as it's sometimes referred to, is the result of burning fossil fuels. This releases additional carbon dioxide into the atmosphere at the rate of about 3 gigatons (3 billion metric tons) per year. Since carbon dioxide (CO2) absorbs heat, we can expect that significant increases in CO2 will tend to raise the global temperature, possibly contributing to global warming. Simply put, if greenhouse gases act like a blanket to keep our planet warm, we are thickening that blanket.\n\nThe natural greenhouse effect on Earth is responsible for life as we know it. We may, however, need to become better stewards of our greenhouse gases in order to preserve life.

it's really interesting.. the 12% answer is correct as a close approximation.\nThe interesting thing to note is that we are supposed to be causing globabl warming. This figure puts makind really into a good global perspective.\nThe next thing to do is see how much smoke and gas volcanos and thermal springs pump into the world every year. \nThen add in all the gases caused by animal excrement (include human in the numbers), and all the plantlife on the planet (including photosynthesising plants and animals in the oceans) and you start to build a very good picture that mankind is not causing global warmnig.

GLOBAL WARMING!!! this is a big issue. you could research a lot on that. or you could do the war in Iraq.

I dont know the seriousness in your question but for one, I hate the cold so plz dont suggest puttin the sun off and two, green house gases that TRAP HEAT causes global warming. Not the sun (and yeah yeah, the sun gives off heat, but so does machinary, body heat, lab exothermic reactions, weapons of mass destruction, fires etc)

Global warming is an increase in the average temperature of the Earth's atmosphere and oceans. The term is also used for the scientific theory of anthropogenic global warming, which attributes much of the recently observed and projected global warming to a human-induced intensification of the greenhouse effect. In this theory, the increased volumes of carbon dioxide and other greenhouse gases released mainly by the burning of fossil fuels, and, to a lesser extent, land clearing and agriculture, are the primary sources of warming. The natural greenhouse effect keeps the Earth about 33 °C warmer than it otherwise would be; adding carbon dioxide to an atmosphere, with no other changes, will make a planet's surface warmer. Current research is attempting to further illuminate and quantify the processes and factors that can affect temperature change, especially positive and negative feedback mechanisms.

Global warming refers to the increases in the average temperature of the Earth's atmosphere and oceans that has been observed in recent decades. The scientific opinion on climate change is that the average global temperature has risen 0.6 ± 0.2 °C over the 20th century, and that it is likely that "most of the warming observed over the last 50 years is attributable to human activities". The increased volumes of carbon dioxide and other greenhouse gases (GHGs) released by the burning of fossil fuels, land clearing and agriculture, and other human activities, are the primary sources of the human-induced component of warming.\n\nObservational sensitivity studies and climate models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures may increase by between 1.4 and 5.8 °C between 1990 and 2100. The range of uncertainty results in large part from not knowing the volume of future carbon dioxide emissions. In addition, there is uncertainty about the climate sensitivity.The increase in global temperatures is expected to result in other changes including rises in sea level and changes in the amount and pattern of precipitation. Such changes may increase the frequency and intensity of extreme weather events such as floods, droughts, heat waves, and hurricanes. This may also cause lower agricultural yields, glacier retreat, reduced summer streamflows, or contribute to biological extinctions. Although warming is expected to affect the number and magnitude of these events, it is difficult to connect any particular event to global warming. Although most studies focus on the period up to 2100, warming (and sea level rise due to thermal expansion) would be expected to continue past then, since CO2 has a long average atmospheric lifetime. [1].\n\nThere are only a few scientists who contest the view that humanity's actions have played a significant role in increasing recent temperatures. However, more significant uncertainties exist regarding how much climate change should be expected in the future, and a hotly-contested political and public debate exists over what, if anything, should be done to reduce or reverse future warming, and how to cope with the consequences.\n\nThe term 'Global warming' is a specific case of the more general term 'climate change' (which can also refer to cooling, such as in Ice ages). Furthermore, the term is in principle neutral as to the causes, but in common usage, 'global warming' generally implies a human influence. Note, however, that the UNFCCC uses 'climate change' for human caused change and 'climate variability' for non-human caused change [2]. Some organizations use the term 'anthropogenic climate change' for human induced changes.

We had a bit of summer the other week - maybe that was it for this year! Thank Mr George W Bush and his cronies for not believing global warming is changing the environment!\n\nP.S. I'm in Manchester, UK.

Global warming started long before the "Industrial Revolution" and the invention of the internal combustion engine. Global warming began 18,000 years ago as the earth started warming its way out of the Pleistocene Ice Age-- a time when much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice.\n\nEarth's climate and the biosphere have been in constant flux, dominated by ice ages and glaciers for the past several million years. We are currently enjoying a temporary reprieve from the deep freeze.\n\nApproximately every 100,000 years Earth's climate warms up temporarily. These warm periods, called interglacial periods, appear to last approximately 15,000 to 20,000 years before regressing back to a cold ice age climate. At year 18,000 and counting our current interglacial vacation from the Ice Age is much nearer it's end than it's beginning.\n\nGlobal warming during Earth's current interglacial warm period has greatly altered our environment and the distribution and diversity of all life. For example:\n\n\n Approximately 15,000 years ago the earth had warmed sufficiently to halt the advance of glaciers, and sea levels worldwide began to rise.\n\n By 8,000 years ago the land bridge across the Bearing Strait was drowned, cutting off the migration of men and animals to North America.\n\n Since the end of the Ice Age, Earth's temperature has risen approximately 16 degrees F and sea levels have risen a total of 300 feet ! Forests have returned where once there was only ice.\n\nDuring ice ages our planet is cold, dry, and inhospitable-- supporting few forests but plenty of glaciers and deserts. Like a spread of collosal bulldozers, glaciers have scraped and pulverized vast stretches of Earth's surface and completely destroyed entire regional ecosystems not once, but several times. During Ice Ages winters were longer and more severe and ice sheets grew to tremendous size, accumulating to thicknesses of up to 8,000 feet!. They moved slowly from higher elevations to lower-- driven by gravity and their tremendous weight. They left in their wake altered river courses, flattened landscapes, and along the margins of their farthest advance, great piles of glacial debris.\n\nDuring the last 3 million years glaciers have at one time or another covered about 29% of Earth's land surface or about 17.14 million square miles (44.38 million sq. km.) . What did not lay beneath ice was a largely cold and desolate desert landscape, due in large part to the colder, less-humid atmospheric conditions that prevailed.\n\nDuring the Ice Age summers were short and winters were brutal. Animal life and especially plant life had a very tough time of it. Thanks to global warming, that has all now changed, at least temporarily.\n\nThje maximum CO2 level was 2% over 2.5 million yrs back, at least scientists say that!!

Here's something to dwell on:\n\nGlobal Warming has become a religion run by fanatics reminiscent of the leaders of the darkest days of the Inquisition that nearly destroyed civil society only a few hundred years ago. We are not to question the great god of Global Warming. Those who do are separated from civil society and labeled as heretics. \n\nThe simple truth is there is no scientific consensus on Global Warming. In fact, as the media frenzy screams global warming, there are a growing number of scientists who are expressing their doubts.  In 1992, just prior to the UN’s Earth Summit in Rio de Janeiro, 425 scientists and other intellectual leaders signed The Heidelberg Appeal, a quiet call for reason in dealing with the climate change issue, which expressed a conviction that modern society is the best equipped in human history to solve the world’s ills, provided that they do not sacrifice science, intellectual honesty and common sense to political opportunism and irrational fears. Today, the Heidelberg Appeal has been signed by more than 4,000 scientists and leaders from 100 countries, including more than 70 Nobel Prize winners.\n\nAlso in 1992, another statement from some 47 atmospheric scientists was issued saying greenhouse global warming theories derive from highly uncertain scientific theories. The statement went on to say, "We are disturbed that activists, anxious to stop energy and economic growth, are pushing ahead with drastic policies without taking notice of recent changes in the underlying science."\n\nIn 1995, over 85 scientists and climate experts from research labs and universities worldwide, signed the Leipzig Declaration. In part it says, "In a world in which poverty is the greatest social pollutant, any restriction on energy use that inhibits economic growth should be viewed with caution. For these reasons, we consider ‘carbon taxes’ and other drastic control policies – lacking credible support from the underlying science – to be ill-advised, premature, wrought with economic danger, and likely to be counterproductive."\n\nIn 1997, a Gallop Poll of eminent North American climatologists shows that 83% did not support the claims of the green house theory of Global Warming.  In 1998, The Oregon Institute of Science and Medicine (OISM) issued a petition for signature by atmospheric scientists saying there is no scientific evidence indicating that greenhouse gases cause global warming. That petition was signed by more than 17,000 scientists and leaders involved in the issue. \n\nGlobal Warming scaremongers have tried to discredit these statements from the opposition, saying either they are too old to be counted in today’s debate or that they weren’t signed by real scientists. Neither is true. One only has to look at the signers on the documents and statements to know who and what they are. The relevance of the documents can be answered in two ways. First, most of the signers of these documents from the 1990’s hold the same positions today. Second, as is the fallacy in the Global Warming debate, such drastic climate changes, as described by scaremongers, would not come about overnight. Though the proponents would have you believe otherwise, 15 years is but a microsecond in the study of the earth’s activities.\n\nHowever, there is great question about the validity of the documents promoted by the Global Warming crowd. In May 1996, unannounced and possibly unauthorized changes to the United Nation’s report on climate change touched off a firestorm of controversy within the scientific community. The Intergovernmental Panel on Climate Change the science group that advises the United Nations on the global warming issue, presented a draft of its report in December 1995, and it was approved by the delegations. However, when the printed report appeared in May 1996, it was discovered that substantial changes and deletions had been made to the report to make it conform to the P

Mission Impossible:  HONESTY AND TRUE REPRESENTATION PLEASE.  As far as issues goes, lets see if the pres. can have the balls to say YES there really is GLOBAL WARMING!!  Not necessarily do anything about it but at least acknowledge it does exist would be nice.

Global warming is believed to be an average raise in temperature.  Not all areas will experience it (if it even exists).  But the Earth goes through weather cycles (as in the cold cycle when there were glaciers covering the Earth, we are now just entering into the warm phase).  This is my theory.  But, as I said, it will not be total, constant raise in temperature.  Some spots will notice the difference, others won't.  It's an overall average.
