what are the effects of global warming?

As more and more forest are destroyed, fewer plants are left to take in carbon dioxide for use in photosynthesis. On the other hand, people keep on using energy and fuel and burning materials that produce more and more carbon dioxide. There is therefore a surplus of carbon dioxide in the air. You have to remember that carbon dioxide is one of the major green house gases in the atmosphere. These gases warm our atmosphere by converting solar infrared radiation into heat energy. What's more, the heat is also trapped by these green house gase. With more and more heat being trapped, our climate will change. Higher global temperature will coz the sea level to rise. It will also coz extreme weather conditions such as supertyphoons and tornadoes

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

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 .

causes: -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. This conclusion can be controversial, especially outside the scientific community.Adding 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.Due 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.\neffects: -The predicted effects of global warming are many and various, both for the environment and for human life.

In particular, the relationship between global warming and hurricanes is still being debated. [21] [22] A draft statement by the World Meteorological Organization acknowledges the differing viewpoints on this issue [23].The extent and likelihood of these consequences is a matter of considerable controversy. A summary of possible effects and recent understanding can be found in the report of the IPCC Working Group II [24]. Some scientists believe global warming is already causing death and disease across the world through flooding, environmental destruction, heat waves and other extreme weather events.

Well Global warming is a great threat, it is damaging planet earth. I was reading in this physics book about the effects of global warming and it stated that the rising levels of harmful chemical gases in the earth's atmosphere could damage the earth forever. It says the with the build up of sulphur dioxide, nitrogen, methane, ammonia and carbon dioxide in the earth's atmosphere, a giant chemical ring will form around the earth's atmosphere blocking sunlight coming into earth, so therefore the earth turns into "lo" one of jupiter's many moons. I'm not saying that this is true, but that's what i read in my book.

Global warming can occur from a variety of causes, both natural and human induced. In common usage, "global warming" often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities. See climate change, greenhouse effect, enhanced greenhouse effect, radiative forcing, troposphere.\n\n\nSource: 2006 U.S. Inventory of Greenhouse Gas Emissions and Sinks: Fast Facts (PDF, 2 pp., 220 KB, About PDF)\nGlobal Warming Potential (GWP)\nGlobal Warming Potential (GWP) is defined as the cumulative radiative forcing effects of a gas over a specified time horizon resulting from the emission of a unit mass of gas relative to a reference gas. The GWP-weighted emissions of direct greenhouse gases in the U.S. Inventory are presented in terms of equivalent emissions of carbon dioxide (CO2), using units of teragrams of carbon dioxide equivalents (Tg CO2 Eq.).\n\nConversion: Tg = 109 kg = 106 metric tons = 1 million metric tons\n\nThe molecular weight of carbon is 12, and the molecular weight of oxygen is 16; therefore, the molecular weight of CO2 is 44 (i.e., 12+[16 x 2]), as compared to 12 for carbon alone. Thus, carbon comprises 12/44ths of carbon dioxide by weight.\n\nSee radiative forcing, carbon dioxide equivalent.\n\nGreenhouse Effect\nTrapping and build-up of heat in the atmosphere (troposphere) near the Earth’s surface. Some of the heat flowing back toward space from the Earth's surface is absorbed by water vapor, carbon dioxide, ozone, and several other gases in the atmosphere and then reradiated back toward the Earth’s surface. If the atmospheric concentrations of these greenhouse gases rise, the average temperature of the lower atmosphere will gradually increase. See greenhouse gas, anthropogenic, climate, global warming.7\n\nGreenhouse Gas (GHG)\nAny gas that absorbs infrared radiation in the atmosphere. Greenhouse gases include, but are not limited to, water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), ozone (O3 ), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). See carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride.7\n\n\n\n\ngreenhouse effect  a warming process that balances Earth's cooling processes and helps maintain an average global temperature of approximately 60 degrees Fahrenheit. During this process, sunlight enters Earths atmosphere as short wave radiation. The radiation is absorbed by Earth's surface. The planet becomes heated and emits long wave radiation toward the atmosphere. In the atmosphere, some of the long wave radiation is absorbed by certain gases called greenhouse gases.  Each molecule of greenhouse gas becomes energized and emits heat energy in all directions.  By radiating heat energy toward Earth , greenhouse gases increase Earth's temperature. Note that the warming mechanism for the "greenhouse effect" is NOT exactly the same as the warming mechanism of greenhouse walls. While greenhouse gases absorb long wave radiation then emit heat energy it in all directions, greenhouse walls physically trap heat inside of greenhouses and prevent it from escaping to the atmosphere.\n\ngreenhouse gases  certain gases in the Earth's atmosphere that absorb some of the outgoing long wave radiation, or heat energy (see greenhouse effect). These gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

global warming is real. its extremey or may not be related toinitially global warming causes the polar caps to melong termea water to rise and become lower in saline concentrations.\nthe lower the salt content the less the currents of the ocean flow and the COLDER the winters get (warm water not moving away from the equator) \nin natural cycles the more extreeme cold kills off organisms initally resulting in HIGHER greenhouse gases, but longterm the "ice age" that follows will leave less life (and death) reducing the overall emissions. this also increases the amount of icebound water increasing the salinity in the oceans returning the currenty\n\nSo You decide on the cause but it is real and geologically recorded again and again.

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades

Global warming is causing polar ice caps to melt, causing an increase in ocean levels. Recently, a stream that runs right to the north pole completely melted, and polar bears have been drowning. Also, storms will become more frequent and severe, and everywhere will get hotter. This means thatthe diseases and viruses common in tropical places will become common everywhere.

The increase of the greenhouse gases --> Carbon Dioxide, CFCs, Methane! Nitrogen oxiode.\n\nGases such as carbon dioxide trap heat and since deforestion is occuring rapdily there is less trees to take in carbon dioxide so the amount of carbon dioxide increases. With the amount of carbon dioxide increased more heat is absorbed and it is stuck on the Earth. \n\nAlso another form of global warming is the depletion of the ozone layer. CFC's contains a chemical that destroys the Ozone layer and the Ozone layer is a protective shield of the Earth. It gets rid of the harmfull sun's ultraviolet rays and without the ozone layer the UV rays can freely enter the Earth.

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.

Increasing wind strength and resulting storm damage will be a global problem. An increase in desertification will hit the inland countries, alterations to the sea level will affect coastal countries.\n\nThe cold temperate zone will actually get colder, less habitable - affecting developed countries only. If the warming  cuts off the gulf stream, the pendulum might swing back and cause glaciation - an ice age. While this will directly affect the developed countries, the developing countries will have to cope with yet less available water. A lose-lose situation...
