what is the climatic variability of global warming?

I do not understand your question. If the climate warms, then surely it will change. \n\n\nIf there is a bigger difference between the cold areas and the warm areas on the planet, storms might be more violent, and there might be more variability in the weather.

NO because of all the new cars and fossil fuel that people are burning. because of that the hi concentration of Co2 in the atmosphere Will result in global warming. In the last 100 years the global temperature has GROWN by 1 degree Celsius. and in the next 50 years or so the temperature Will rise by another 3 degrees resulting in freak weather.

Yes, global warming has started and finished and started and finished.\n\nThe earth has been much warmer before and much colder.  It will be both much warmer and much colder again many times.

(m)\n\nThe difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time. \n\nWhen we talk about climate change, we talk about changes in long-term averages of daily weather. Today, children always hear stories from their parents and grandparents about how snow was always piled up to their waists as they trudged off to school. Children today in most areas of the country haven't experienced those kinds of dreadful snow-packed winters, except for the Northeastern U.S. in January 2005. The change in recent winter snows indicate that the climate has changed since their parents were young. \n\nIf summers seem hotter lately, then the recent climate may have changed. In various parts of the world, some people have even noticed that springtime comes earlier now than it did 30 years ago. An earlier springtime is indicative of a possible change in the climate. \n\naddition to long-term climate change, there are shorter term climate variations. This so-called climate variability can be represented by periodic or intermittent changes related to El Niño, La Niña, volcanic eruptions, or other changes in the Earth system

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.

Greenhouse Effect, the capacity of certain gases in the atmosphere to trap heat emitted from the Earth’s surface, thereby insulating and warming the Earth. Without the thermal blanketing of the natural greenhouse effect, the Earth’s climate would be about 33 Celsius degrees (about 59 Fahrenheit degrees) cooler—too cold for most living organisms to survive.\n\nThe greenhouse effect results from the interaction between sunlight and the layer of greenhouse gases in the Earth's atmosphere that extends up to 100 km (60 mi) above Earth's surface. Sunlight is composed of a range of radiant energies known as the solar spectrum, which includes visible light, infrared light, gamma rays, X rays, and ultraviolet light. When the Sun’s radiation reaches the Earth’s atmosphere, some 25 percent of the energy is reflected back into space by clouds and other atmospheric particles. About 20 percent is absorbed in the atmosphere. For instance, gas molecules in the uppermost layers of the atmosphere absorb the Sun’s gamma rays and X rays. The Sun’s ultraviolet radiation is absorbed by the ozone layer, located 19 to 48 km (12 to 30 mi) above the Earth’s surface.\n\nAerosols, also known as particulates, are airborne particles that absorb, scatter, and reflect radiation back into space. Clouds, windblown dust, and particles that can be traced to erupting volcanoes are examples of natural aerosols. Human activities, including the burning of fossil fuels and slash-and-burn farming techniques used to clear forestland, contribute additional aerosols to the atmosphere. Although aerosols are not considered a heat-trapping greenhouse gas, they do affect the transfer of heat energy radiated from the Earth to space. The effect of aerosols on climate change is still debated, but scientists believe that light-colored aerosols cool the Earth’s surface, while dark aerosols like soot actually warm the atmosphere. The increase in global temperature in the last century is lower than many scientists predicted when only taking into account increasing levels of carbon dioxide, methane, nitrous oxide, and fluorinated compounds. Some scientists believe that aerosol cooling may be the cause of this unexpectedly reduced warming. \n\nEffects:\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\nThe predicted effects of global warming are many and various, both for the environment and for human life. These effects include sea level rise, impacts on agriculture, reductions in the ozone layer , increased intensity and frequency of extreme weather events, and the spread of disease. In some cases, the effects may already be being experienced, although it is impossible to attribute specific natural phenomena to long-term global warming. In particular the relationship between global warming and hurricanes is still being debatedFour new papers correlating climate change with increased hurricane intensity seem to be making the case that the two phenomena are linked , a draft WMO statement acknowledges the different viewpoints .

Global warming and cooling has occurred throughout history, so in a sense, yes, global warming has happened since the last ice age.  The differences between the average temperatures on earth correlate to the amount of CO2 in the atmosphere (one of the greenhouse gases).  The global warming that has scientists concerned lately has to do with how humans have increased the amount of CO2 in the atmosphere and how this might be related to recent warming trends.

Global warming causes the world's mean ocean temperature to rise.  This makes hurricanes more likely to form because they need ocean temperatures above 80 degrees fahrenheit to form.  Since hurricanes often create tornados, they are also more likely to form.  Global warming's level of severity depends on exactly where you're talking about.  You'd have to specify to get a more definite answer.

The climate system varies both through natural, "internal" processes as well as in response to variations in external "forcing" from both human and non-human causes, including solar activity, volcanic emissions, and greenhouse gases. Climatologists agree that the earth has warmed recently. The detailed causes of this change remain an active field of research, but the scientific consensus identifies greenhouse gases as the primary cause of the recent warming. Outside of the scientific community, however, this conclusion can be controversial.\n\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. It is therefore not correct to say that there is a debate between those who "believe in" and "oppose" the theory that adding carbon dioxide or methane to the Earth's atmosphere will, absent any mitigating actions or effects, result in warmer surface temperatures on Earth. Rather, the debate is about what the net effect of the addition of carbon dioxide and methane will be, when allowing for compounding or mitigating factors.\n\nOne example of an important feedback process is ice-albedo feedback. The increased CO2 in the atmosphere warms the Earth's surface and leads to melting of ice near the poles. As the ice melts, land or open water takes its place. Both land and open water are less reflective than ice, and so absorb more solar radiation. This causes more warming, which in turn causes more melting, and the cycle continues.\n\nDue to the thermal inertia of the earth's oceans and slow responses of other indirect effects, the Earth's current climate is not in equilibrium with the forcing imposed by increased greenhouse gases. Climate commitment studies indicate that, even if greenhouse gases were stabilized at present day levels, a further warming of perhaps 0.5 °C to 1.0 °C (0.9–1.8 °F) would still occur.

in ten years i think the major change will be that global warming is universally accepted because the climate will become more unstable.  The better name for global warming is climate change because, while the overall temperature of the earth is rising (ever so slightly) the key indication/affect is changes in climate (which includes differences in storm activity from the recent past).\n\nBut basically, yeah the huricanes and wind storms and early and late and heavy and light seasons will become more noticable, even in 10 years.

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.

Global warming has two main applications. The first is that there are certain gases that trap heat in the atmosphere, warming planets. This is known to take place on Venus, Earth, and the gas giants. Earth is the hospitable place that it is because of global warming.\n\nThis takes place because of greenhouse gases, which allow radiation from the sun to pass through the atmosphere and warm the surface of the earth. The surface then re-radiates this energy back towards space in the infrared spectrum. This energy would escape and our planet would be as cold as the moon, were it not for the greenhouse gases (mainly CO2, ozone, methane, and water vapor). They absorb the infrared energy and radiate it back to earth, increasing the overall amount of radiation hitting the earth's surface, keeping it warm day and night.\n\nThat this takes place is clear and indisputable. There is simply too little energy coming from the sun to account for our planet's temperature. The controversial point is when global warming is applied to the current rise in average global temperature that has taken place over the past 50 so years. Most scientists believe that warming of the planet is due to increases in greenhouse gases, mainly CO2, mainly due to human activities on earth.

Global warming is caused by an increase in greenhouse gasses in the atmosphere.  Global warming has been proven, the only people who argue against it have no understanding of science and no idea what is going on in the world.  Humans are not the only cause of greenhouse gasses, but we contribute to the problem greately.  The fact is that the earth cycles through warming and cooling periods but manking disturbs the normal process and increases the rate of warming (mostly by CO2 increases from burning oil.)  There are natural sources of CO2 and other greenhouse gasses as well, volcanoes can spew millions of tons of CO2 in a matter of days... the earth has supported life through very hot and very cold peroids, but there is NO realistic argument that humans don't influence global warming.\n\nThe greenhouse effect is necessary for life as well, if all of the CO2 was elimated from the atmosphere life as we know it on earth would end, the earth would be a frozen, barren wasteland.  Without any greenhouse gasses the earth would not maintain a reasonable temperature; nights would drop to -80 Celcius on the warm parts of the planet... \n\nThe earth will recover from all of the damage we do when we are gone... life adapts, species are eliminated every year, but no little coverage is given to the new species the are discovered every year... evolution is in progress, global warming is a change, not a destruction.

Global Warming is a natural phenomenon. The earth's temperature has gone through warming and cooling cycles naturally throughout history. The ice age was not caused by prehistoric humans and neither was the global warming that melted it. So basically, there is nothing we can do but adapt to it.
