what is the global warming?
600459
Global warming is the opposite of global cooling.  The Earth has gone through at least 3 episodes of cooling/warming.  Where I am sitting now was once under about 1000 feet of ice.  The Earth warmed up enough to melt all that ice -- and this was way before there were any cars or industry (or even people).  Global warming is NOT caused by people living their lives and producing things. People may have an effect on the rate, but we are not the CAUSE. BTW, the ozone layer hole, which expands and contracts, has no direct effect on global cooling/warming.

Global warming is the latest trend by Governments of the world to try to convince the population that we are at fault for warming the world.  The world's weather and climate has been changing regularly over the last 15,000 years - before cars and planes were invented.  Carbon dioxide is one of the most prolific gasses in our atmosphere because it is needed for plants to survive.  Without CO2, the plants would die and we would have no oxygen which is a by product of a plant and we would all die!  Remember all the other scare stories over the years - in the 60s it was nuclear bombs from Russia, then we had SARS and bird flu, then terrorists and don't forget the hole in the ozone layer.  Every couple of years, we get a major scare story to keep the world's population under control.  The effect of global warming is that we are all paying out so called green taxes that actually do nothing to stop the problem but it sure makes the Governments rich!  What is the point of worrying about future global warming when now you have people freezing to death in the winter because they cannot afford to heat their homes because the price of gas and electric has risen so much because of green taxes?  Or we are getting plagues of rats and other vermin because Councils only collect our rubbish every two weeks because recycling is top priority?  We really should solve todays problems first before we start worrying about something that will most likely never happen.

Global Warming is the increase in temperatures in our climate within our atmosphere. It is caused by liberal politicians and environmental wackos from the US and other western countries yakking, crying and complaining about how our modern way of life ( i.e. anything from industrial, technological and day to day conveniences ) is polluting and destroying the planet. The toxic gasses produced by all their whining and complaining is filling up our atmosphere with warm unfilthy air. The result is a "greenhouse" effect. All that hot, vile and unhealthy  gasses coming out of their mouth is a danger to us all. As a sidebar, I have to note that the environmental wackos and the liberal politicians have different agendas as to why they are crying and complaining, but that is another topic all together. \n\nSo in short, Global Warming is caused by hot air coming out environmentalist and left-wing politicians mouths when whining and complaining about anything. Solution: shut them up. \n\nWhat effect does it have in a million years: it will stump human and humanities growth

Yes, Global warming is a reality.  Anyone who says otherwise is ignorant.   Yes, the earth goes throgh natural warming and cooling phases, we are currently trasistioning into a "hothouse" from an "icehouse" which means we are in an inter-glacial period.\n\nHowever, Humans are doing their part to screw up the atmosphere.  CO2 is a gas that traps heat  and is emmitted by cars, factories, and anything else that burns fuel to work.  All anyone needs to do is look at a graph of the average surface temperture for the earth superimposed on the CO2 level and they will find they are identical in shape.  And the CO2 level has increased exponentially since the industrial evolution.  While the earth's natural cycles have varied the CO2 levels from 150 to 280 parts per million in the last 600,000 years, we are currently at 390 parts per million and rising fast.  No that is not natural, it is caused by humans.\n\nWhat can you do?  Buy a Prius.  Recycle.  Use less - ride you bike more.  Run your AC less, Turn off your lights.  All those hippie things that save energy - they actually work.

Global Warming is the phenomenon of increase in Earths Temperature due to Greenhouse Effect leading to melting of Polar Ice Caps\nAdding carbon dioxide (CO2) or methane (CH4) to Earth's atmosphere, with no other changes, will make the planet's surface warmer; greenhouse gases create a natural greenhouse effect without which temperatures on Earth would be an estimated 30 °C (54 °F) lower, and the Earth uninhabitable.\n\nOZONE layer is the Protective Shielding in the Atmosphere which saves us from harmful solar UV rays.IT is Naturally occuring trace gas, chemical formula O3. In the stratosphere, it serves to absorb many harmful solar UV rays.\n\nEarthquakE------An earthquake is a phenomenon that results from and is powered by the sudden release of stored energy that radiates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes tsunamis, which may lead to loss of life and destruction of property.

the sun..... the sun is the only thing responsible for warming the earth. Dont get me wrong ...pollution and greenhouse gases also contribute. But they are not the only reason. We are in a short period of warm temperatures on earth. A small window in time. We just got out of an ice age about 12-15ooo years ago. We have had longer periods of global Ice Ages than we have of global warm periods in the last few million years.... Did u know that a violent volcano can spew enough greenhouse gas into the atmosphere to warm our atmospheric temperatures several degrees. Pollution does the same thing but on a smaller scale. This gas traps the earths heat from escaping back into space. Its like a blanket for our atmosphere. Then the earth gets warm, and creates more water vapor from the oceans. More water vapor means more clouds. More clouds mean less sunlight hitting the surface of earth, less sunlight means less heat, less heat means more ice.. and we go back into an ice age.... then the earth fixes herself, we start to get warmer.... and we go on and on.... Its been happening like that for millions of years. If it wasent for global warming we wouldnt be alive and the earth would be covered with seals, penguins, polar bears and wolly mammoths.

well, scientists and meteorologists theorise that because of global warming, the ocean's waters are getting warmer and causing more hurricanes and tropical storms to spawn. also, the earth is the warmest it's been in over 2000 years. all you need to know, WE BEAT THE RECORD! :P

global warming is cause by greenhouse gases being trapped near earths atmosphere, which causes heat to be trapped nearer to earths surface which increases the temperature on earth slightly which melts the polar ice caps which makes water levels rise which means islands will be flooded and shores will advance into the land making living space smaller in an already overpopulated world.

People babble a lot on this page! If you don't know the answer properly, please don't answer!!!\n\nGo to the link below, it will tell you all about Global Warming and comes from a legitimate source.

ok now here is some truth for you. Global warming is a THEORY nothing more, it has not been proven. an ALL the scientists do not agree. more than half do not agree and because of that they do not get media coverage. That is why all you hear is global warming on the news because it gets ratings. Many, many scientists agree this is a phase, the earth has wamring periods and cooling periods, we just now are getting out of a cooling period. every here of the "year without a summer" in the 1770's. that was the height of the cooling period. if you look back further in the 1300's it was hotter then, than it is now according to historical evidence. Volcanoes produce almost 10 times the green house gasses then humans produce per year. Nature is not this fragiel little thing like all the libs want you to believe, its very tough and adaptive it recycles many of the wastes we produce but also many of the wastes itself produces which in comparison to ours is infintismal. I agree we should not be reckless and find better, cleaner and more efficient ways to do things. If you want the truth, yes global warming is true, the "globe" is "warming" but not because of the Dodge Diesel you drive, but because its a cycle and in a few centuries it will begin to cool again. Most people here never heard of what these very same scientists were saying in the 70's. the same people screaming about global warming were do the same thing about "global cooling" in the 1970's and some suggested we put coal soot on the ice caps to gather heat from the sun to melt them. Look it up, its true. So before you goes starting going nuta about this global warming farse, do your homework instead of believing everything you hear on the ratings driven news everynight.

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

Short Answer: Carbon dioxide.\n\nLong answer:\nGlobal warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades.\n\nThe prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities".\n\nThe increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming. They are released by the burning of fossil fuels, land clearing and agriculture, etc. and lead to an increase in the greenhouse effect. The first speculation that a greenhouse effect might occur was by the Swedish chemist Svante Arrhenius in 1897, although it did not become a topic of popular debate until some 90 years later.

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.

The principle behind global warming is the same as the process that warms the interior of a greenhouse. Light from the Sun passes relatively easily down through Earth's atmosphere to the surface. Earth's surface warms and radiates heat in the infra-red part of the electromagnetic spectrum. These frequencies don't pass back up through the atmosphere easily but instead are retained by the atmosphere, thus warming it.

Global warming is real, but not really caused by industry and being covered up. Studies show that primary global warming is caused by the build up of Carbon Dioxide in our atmosphere, which is actually caused by our breathing. So as human population increases, so does global warming. The solution is to cut back on world population, but no government is going to admit that we should stop breeding and kill off thousands of people as a solution. Maybe China.

Global warming is a term used to describe the trend of 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, as expressed in the UN Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report in 2001 and explicitly endorsed by the national science academies of the G8 nations in 2005, is that the average global temperature has risen 0.6 ± 0.2 °C since the late 19th century, and that it is likely that "most of the warming observed over the last 50 years is attributable to human activities" [1]. The increased volumes of carbon dioxide and other greenhouse gases 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. The natural greenhouse effect keeps the Earth about 33 °C warmer than it otherwise would be; adding carbon dioxide to a planet's atmosphere, with no other changes, will make that planet's surface warmer.\n\nObservational sensitivity studies [2] [3] and climate models referenced by the IPCC predict that global temperatures may increase by 1.4 to 5.8 °C between 1990 and 2100.\n\nThe range of uncertainty results in large part from not knowing the volume of future carbon dioxide emissions. In addition, there is uncertainty about the accuracy of the underlying climate models.\n\nThe increase in global temperatures is expected to result in other climate 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, change agricultural yields, cause 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.\n\nAlthough most studies focus on the period up to 2100, warming would be expected to continue past then, since CO2 has a long average atmospheric lifetime [4]. Also, Climate commitment studies indicate that there is a further warming of perhaps 0.5 °C to 1.0 °C — already committed but not yet realized.\n \nThere are only a few scientists that contest the view that humanity's actions have played a significant role in increasing recent temperatures. However, uncertainties do 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.

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades.\n\nThe Earth's average near-surface atmospheric temperature rose 0.6 ± 0.2 °Celsius (1.1 ± 0.4 °Fahrenheit) in the 20th century [1]. The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities"[2].\n\nThe increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming[3]. They are released by the burning of fossil fuels, land clearing and agriculture, etc. and lead to an increase in the greenhouse effect. The first speculation that a greenhouse effect might occur was by the Swedish chemist Svante Arrhenius in 1897, although it did not become a topic of popular debate until some 90 years later. [4]\n\nClimate sensitivity is a measure of the equilibrium response to increased GHGs, and other anthropogenic and natural climate forcings. It is found by observational [5] and model studies. This sensitivity is usually expressed in terms of the temperature response expected from a doubling of CO2 in the atmosphere. The 2001 IPCC report estimates a likelyhood between 66% and 90% for a climate sensitivity in the range 1.5–4.5 °C (2.7–8.1 °F)[6]. This should not be confused with the expected temperature change by a given date, which also includes a dependence on the future GHG emissions and a delayed response due to thermal lag, principally from the oceans. Models referenced by the Intergovernmental Panel on Climate Change (IPCC), using a range of SRES scenarios, project that global temperatures will increase between 1.4 and 5.8 °C (2.5 to 10.5 °F) between 1990 and 2100.\n\nAn increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacial retreat, reduced summer stream flows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming. Although most studies focus on the period up to 2100, warming (and sea level rise due to thermal expansion) is expected to continue past then, since CO2 has an estimated atmospheric lifetime of 50 to 200 years. [7]. Only a small minority of climate scientists discount the role that humanity's actions have played in recent warming. However, the uncertainty is more significant regarding how much climate change should be expected in the future, and there is a hotly contested political and public debate over implementation of policies that deal with predicted consequences, what, if anything, should be done to reduce or reverse future warming, and how to deal with the predicted consequences.\n\nYou could get more information from the link below...
