What is Global Warming?
342379
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.

Here is the problem with global warming.\n1.  We do not know that it is occurring.\n2.  Even if it is occurring, we do not know if the sun is to blame, like with the melting of Martian polar caps, or if it is planet caused.\n3.  Even if it is planet caused, we do not know if it is nature, like when Krakatoa and Helens blew, or man caused.\n4.  Even if it is man caused, we do not know if the overall effects of an increased growing season and farmland increase is a bad thing.\n5.  Even if it is bad, we do not know if we can reverse it.\n6.  Even if we can reverse it, we do not know if it is more economically efficient to adapt or to try to reverse it.\n\nBut think instead of wack a mole at chucky cheese you could play club a seal in alaska.  Could be fun.

Global warming is an increase in the average temperature of the Earth's atmosphere and oceans. The term is also used for the more specific scientific theory of anthropogenic global warming, which states that much of the recent observed (and projected) global warming is human-induced and the result of a strengthened greenhouse effect caused by man-made increases in carbon dioxide (through the burning of fossil fuels and deforestation) and other greenhouse gases. The natural greenhouse effect keeps the Earth 30 °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 tries to uncover more details, e.g. about positive and negative feedback mechanisms, to allow a more precise quantification of the effect.

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 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. On 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 30 °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 find out more details about the processes and factors that would affect a temperature increase especially about positive and negative feedback mechanisms, to allow a more precise quantification of the effects of global warming.\n\nTemperature change is just one aspect of the broader subject of (human-induced) climate change. The scientific opinion on climate change, as expressed by the UN Intergovernmental Panel on Climate Change (IPCC) and explicitly endorsed by the national science academies of the G8 nations, 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]. A small minority of qualified scientists contest the view that humanity's actions have played a significant role in increasing recent temperatures. 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 actions, if any, should be taken in light of global warming.\n\nBased on basic science, observational sensitivity studies, and the climate models referenced by the IPCC, temperatures may increase by 1.4 to 5.8 °C between 1990 and 2100 [2]. This 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 of extreme weather events such as floods, droughts, heat waves, and hurricanes, change agricultural yields, or contribute to biological extinctions. Although warming is expected to affect the number and magnitude of these events, it is very difficult to connect any particular event to global warming.

Global Warming is cause by solar activity.  The increase in the number of sun spots causes the earth to warm.  The temperatures were hotter in the 1920 than now.  The hurricanes were also just as bad then as now.  A rise in CO2 from 1/4% to 1/3% in the atmosphere has no impact on global temperature.  The scientific community has only been accurately measuring temperatures for 30 years.  The only validated temperature measurement of the earth is from the polar satellite.  In 30 years it has only seen on temperature anomaly.  A rise of 1/4 of a degree caused by the full moon.  No other measurement system has shown the accuracy to measure this rise.  Therefore they are not! The polar ice cap has only been watched for 30 years by satellite.  No one measured it before, so how can they say it is now melting for all time.  They don’t know, they are drawing 1000 year conclusions with 30 years of data.  Not possible, not valid.

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.

Global warming occurs naturally and is essential for life on Earth, but today, 99.5% of green house gases are caused by human energy industries, transportation, and commercial use.

Global warming is the theory that the Earth's atmosphere and oceans are getting warmer due to pollution and other environmental factors induced by humans.\n\nSome of the factors include burning fossil fuels (oil) and deforrestation (trees remove carbon dioxide from the atmosphere).\n\nThere's discussion that if the effects of global warming aren't counteracted, ice caps will melt, sea levels will rise, and weather patterns could be altered. \n\nLow-lying coastal cities such as Bangladesh or New Orleans could be wiped out within the next 100 years as sea levels rise. Weather patterns could be altered, bringing drought to areas that used to have lots of rain, and rain to areas that used to be arid.\n\nRead any of the sources below, and you'll find more information about the causes and potential effects. It's definitely something that shouldn't be ignored.

You take all the temperatures across the globe and average them out and compare to the same day and time every year and when the average is steadily getting higher, like it is, its called global warming.\n\nThe ice caps start to melt, sea level rises, climate changes.  Just a whole lot of fun stuff like that.

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.

The greenhouse effect is a natural process in which gases in the upper atmosphere trap heat in the planet.  greenhouse gases is carbon dioxide.  Scientists are concerend about this because carbon dioxide is increasing, therefore intensifying the greenhouse effect.  This can lead to global warming, which might melt the ice caps at the poles and submerge coastal cities in up to 100 meters of water.

Global warming is a plot devised by scientists of the world to dominate the planet !!!\n\nYou see if we accept this theory as fact from then on scientists will be able to control everything that we do based on the complex interactions, almost unfathomably complex, between consumption and global warming effects -- thus, scientists will be allow to make educated guesses if they like, which will almost always certainly result in politically correct and repressive conclusions that forward the goals of this neo-imperialism.\n\n\nThe bottom line for this question is that the LONGEST historical charts showing the temperatures on Earth show that we are currently quite COLD !!!  In fact we are currently tied for the coldest period ever on the long term charts, the entire period if life on Earth. Thus, odds are very good that temperatures will raise no matter what we do so over the very long term scientists will be found to be correct that the Earth is indeed warming up. And I am sure they will continue to blame the heating on human activity and they will continue to try to use this to gain control over the free peoples of the world. Although since this trend that shows the Earth being currently quite cold is a very long term trend, in the million of years, so this is a long term gamble for the scientists a lot can happen between now and when the longer term trend is likely to kick in.\n\nBut the idea that this heating is unnatural or some how damaging to the Earth is silly because the long term charts show that the Earth is usually much warmer, during the last 542 million years, the entire period of time that life has existed on Earth.\n\nEvery classroom and library show have a large poster on the wall to show the temperature record of the Phanerozoic period, the last 542 million years, to remind people of the absurd conclusions science can reach from time to time.\n\nIsn't it interesting that 542 million years shows that we are currently tied for the coldest temps EVER !!!\nhttp://en.wikipedia.org/wiki/Image:Phanerozoic_Climate_Change.png\n\n"The Phanerozoic (occasionally Phaenerozoic) Eon is the period of geologic time during which abundant animal life has existed. It covers roughly 545 million years and goes back to the time when diverse hard-shelled animals first appeared. The Phanerozoic eon is still ongoing." \nhttp://en.wikipedia.org/wiki/Phanerozoic\n\nIf you look at the chart of Holocene temperature variation we are not hotter, on the average we are cooler -- notice the long term cooling trend or downward slope of the chart.\nHolocene Temperature Variations ...\nhttp://en.wikipedia.org/wiki/Image:Holocene_Temperature_Variations.png\n\nFrom this chart it looks like we are currently on the top of an upward swing that started with the mini-ice-age in the 1600s and that we are currently topping out.\n\nThis is probably why scientist are currently predicting in the future, both, much HOTTER weather, and a new ice-age, it is because it is time for a new long term downward trend -- well, that is on the short term chart showing the thousands of years, yes in terms of millions of years we are still currently VERY cold !\n\nAnd 5 million years of temps changes shows we are cooler, but fluctuating ...\nhttp://en.wikipedia.org/wiki/Image:Five_Myr_Climate_Change.png\n\nAnd 65 million years of temps changes shows we are\ncooler, but fluctuating ...\nhttp://en.wikipedia.org/wiki/Image:65_Myr_Climate_Change.png\n\nIsn't it interesting that 542 million years shows that\nwe are currently tied for the coldest EVER !!!\nhttp://en.wikipedia.org/wiki/Image:Phanerozoic_Climate_Change.png\n\nSo I think the scientists that know about this LONG term temperature change believe we will get hotter no matter what, so they can't loose even if the current theories of Global Warming turn out to be BULL of planetary proportions !!!\n\nThe ice-age temps shows our current temps to be fairly typical, notice the other peaks were HIGHER and sh

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
