That's kinda like asking if it's alright to go to the sun as long as I go at night

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.

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 refers to the increases in the average temperature of the Earth's atmosphere and oceans that has been observed in recent decades.

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. 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 difficult to attribute specific natural phenomena to long-term global warming. 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.

In short, Carbon Dioxide, currently being blamed for global warming is the product of burning Carbon based fuels like methane, and also petrolium based fuels.  \n\nCarbon Dioxide (CO2) is also taken out of the air by plants, algae, and bacteria that perform photosynthesis, and is added to a sugar like molecule to produce glucose (a sugar).  The plant or bacteria then uses the glucose for fuel or stores it as starch.  \n\nWe are producing CO2 so fast that plants and algae are not taking it out of the atmosphere as fast as it is being produced.  The extra gas contributes to global warming and climate change.  The excess CO2 also may result in the future in massive increases of photosynthetic algae and bacteria which also could be bad for the oceans, having side effects such as killing all of the fish in the ocean if we are not lucky.

yes.  Hurricanes redistribute the heat of the planet.  The planet is trying to rebalance itself.

This is such a confused issue. \n\nThe short answer is: maybe, but we really do not know. \n\nThe greenhouse gases that are in the earth's atmosphere now keep its temperature warmer by about 60 degrees F. These gases include water vapor (the most important), carbon dioxide, methane, and a few others.\n\nHow might humans increase the net number of greenhouse gases?\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - \n\n\nBurning fossil fuels like coal and natural gas and oil results in the introduction of carbon dioxide into the atmosphere. Burning wood also does so. Deforestation might reduce carbon dioxide sinks. Ocean pollution might also reduce carbon dioxide sinks by killing phytoplankton. Eutrophication (fertilizer in the water) creating algal blooms might also reduce carbon dioxide sinks (at least in the long run when they die and then rot, releasing more carbon dioxide). \n\nRaising cattle and growing rice can increase the greenhouse gas methane. CFCs and HCFCs are greenhouse gases produced by man. Ozone produced in our cities is also a greenhouse gas. Nitrous oxide produced by agriculture and industry is another greenhouse gas.\n\nDoes this have anything to do with global warming?\n - - - - - - - - - - - - - - - - - - - - - - - - - - - \n\nWe do not really know if the global warming we have observed in the last 100 years is natural, or due to human intervention. It might be some other process, like change in solar output. We really do not know, to be honest.  \n\nSo there are a lot of uncertainties. We just do not know, to be honest.

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.

Absolutely.  Interestingly enough, though, there is also such a thing as particle refraction.  This is the pollution particles (mostly sulfates) in the air forming droplets and mixing with clouds.  These smaller particles reflect more light than unpolluted drops, therefore refracting much light and warmth from the earth.  This is referred to as global dimming.  Global dimming actually helps to balance out the global warming.  If we were to somehow end all particle pollution, then the earth would warm at a faster rate.  Without the global warming, the particle pollution would eventually freeze us out.  Therefore, if we end either process of pollution, we must end both or the earth will suffer grave consequences.  If you want more proof of global warming, investigate the hurricane trend of the last few years.  We have had an increase in the frequency of hurricanes because the ocean waters are warmer--check National Geographic, I remember an article in August or September of last year.

Yes, it's a climate thing.

Global warming is mostly caused by humans because we release carbon dioxide (CO2) into the atmosphere by burning wood, driving cars, burning other fossil fuels etc.\n\nuse this site for more info: http://en.wikipedia.org/wiki/Global_warming . Even though it's wikipedia, it's got accurate information.

If you mean global warming, it's the scientific observation that the earth's temperature is rising over a period of time This is resulting in polar melting, raising the ocean level and affecting other weather patterns.

You are absolutely right. It is a cycle.  We last had global cooling around 1650AD.  Did you know that water vapor has more of an effect on global warming than CO2?  In fact 2/3 of the increase in CO2 levels occurred way before we even started burning the fossil fuels!!\n   The good man above me is right that ice ages occur more often than 2 million years. In fact the last "little ice age" occurred around the Maunder minimum which forced the Vikings off of Greenland.  He is right about the sun spot activity too.\n   Wow this is very encouraging that other people have the true facts and aren't being fooled.\n   Did you know that about 99% of the weathermen think like we do?  Only problem is you have to go with the flow to get any funding these days.

definitely. it's practically the one part of global warming scientists agree on.\nover the next century, we will see the oceans warming and thus expanding (sadly flooding places like Venice), also the polar ice caps melting (once again, not good. they keep the earth cool...see a vicious cycle?), not to mention serious climate change and animals migrating to the north to keep cool. it's already happening...yikes!

Global warming and cooling, in nature, has cycles beyond our control. AS a species, we have vastly accelerated the warming by CO2 emissions from burning of fossil fuel. The CO2 is/has formed higly reflective shield around the globe that holds heat IN, yet allows sunlight to go through it. The heat builds up, but cannot escape fast enough to prevent warming of the planet. We have reached a critcal stage in this cycle. IF we do not greatly reduce CO2 emissions within the next 10 years, it will be too late for us to stop the cycle that has started. Ice caps will melt and the surface of the Earth will change drastically. Storms will intensify dramatically, having more and more heat to power them. WE are within just a few years of a catastrophe, and yet, no one seems willing to act upon it, in fact, no one seems to even acknowledge the pending disaster. Life as we know it will be very different than it is today. WE are, time wise, just around the corner from a life threatening climate which will be conducive to an instant ICE AGE. If you have any doubt, see the movie, "Day After Tomorrow." The premise of the movie is NOT sci fi...it is very real.

Not really but in fact the bigger problem is not CO2 but CO. Never the less you know that CO2 levels have suffer a cycle since the beginning earth however since the Industrial revolution they climbed hugely the climate has already changed. At least in my part of the planet it is hotter generally I notice it, my parents did and my friends in general, but it is the older people that notice it the most. The climate is cyclic, sometimes it makes things from 100 to 100 years and at the beginning one thought it might be that but it’s not it’s really a matter of global warming. (I am portuguese to now more about the fire in summer consult the web or see it in CNN in the summer), it is real and it is now
