it's really interesting.. the 12% answer is correct as a close approximation.\nThe interesting thing to note is that we are supposed to be causing globabl warming. This figure puts makind really into a good global perspective.\nThe next thing to do is see how much smoke and gas volcanos and thermal springs pump into the world every year. \nThen add in all the gases caused by animal excrement (include human in the numbers), and all the plantlife on the planet (including photosynthesising plants and animals in the oceans) and you start to build a very good picture that mankind is not causing global warmnig.

No, becasue, if you ever watch old shows from the 70's.. they were all hyped up that there was an ice age coming. odd how we suddenly changed it into global warming? yes.\n    if you actually study charts of the history of our planet's heating and cooling over time, its quite normal for earth to heat up and cool down by a few degrees over a couple hundred years. \n    do you know where the big concern is? 1.5 degrees on average. Over 200 years. of course a BIT of it might have been influenced by the coming of the industrial revolution, but as already mentioned on here, volcanoes etc give way more crap into the atmosphere than we ever did. and besides.. with all the tree huggers etc businesses arent allowed to put nearly as much gas into the atmposhere as before. we're almost cleaner than before the industrial revolution. we dont use coal furnaces... everything is cleaner on the whole. \n       and also.. i always find this funny...if you look up the past ice ages... you'll notice how the tempurature rises for a time steeply.. then plunges. i forget the interval of years exactly... but i do know we're ready... and guess what? then temps rising. i'd be moving towards the equator, not the poles in coming centuries. \n\n      besides... how could ppl make money in the news etc if they didnt make a big hype about something so non-effecting as global warming? they should at least get their information straight and threaten us about an ice age. then maybe you can beleive them.\n\nif all else fails people... DO YOUR OWN RESEARCH! dont trust what everyone else says. you cant even tell where the facts are coming from.

A good place to start will be to look at the following websites \n\nThermal Energy and States of Matter\nhttp://www.pschweigerphysics.com/thermenergy.html\n\nThermal Energy\nhttp://sol.sci.uop.edu/~jfalward/physics17/chapter6/chapter6.html\n\nThermodynamics and Thermal Physics guides\nhttp://physics.about.com/cs/thermodynamics/\n\nIf your doing a project you might look into "Ocean Thermal energy conservation" as a topic.\n\nOcean Thermal energy conservation is used to generate electricity using the temperature difference of seawater at different depths

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 is associated with sun spots. So if the sun spots disappear we will probably have a period of global cooling but maybe not an ice age. The last period of global cooling was around the year 1650 AD.  That period is called the "Maunder Minimum".

One of the most hotly debated topics on Earth is the issue of climate change, and the National Environmental Satellite, Data, and Information Service (NESDIS) data centers are central to answering some of the most pressing global change questions that remain unresolved. The National Climatic Data Center contains the instrumental records that can precisely define the nature of climatic fluctuations at time scales of a up to a century. Among the diverse kinds of data platforms whose data contribute to NCDC's armamentarium are: Ships, buoys, weather stations, balloons, satellites, and aircraft. The National Oceanographic Data Center contains the subsurface data which reveal the ways that heat is distributed and redistributed over the planet. Knowing how these systems are changing and how they have changed in the past is crucial to understanding how they will change in the future. And, for climate information that extends from hundreds to thousands of years, the paleoclimatology program, also at the National Climatic Data Center, helps to provide longer term perspectives.\n\nThe greenhouse effect is unquestionably real and helps to regulate the temperature of our planet. It is essential for life on Earth and is one of Earth's natural processes. It is the result of heat absorption by certain gases in the atmosphere (called greenhouse gases because they effectively 'trap' heat in the lower atmosphere) and re-radiation downward of some of that heat. Water vapor is the most abundant greenhouse gas, followed by carbon dioxide and other trace gases. Without a natural greenhouse effect, the temperature of the Earth would be about zero degrees F (-18°C) instead of its present 57°F (14°C). So, the concern is not with the fact that we have a greenhouse effect, but whether human activities are leading to an enhancement of the greenhouse effect. \nHuman activity has been increasing the concentration of greenhouse gases in the atmosphere (mostly carbon dioxide from combustion of coal, oil, and gas; plus a few other trace gases). There is no scientific debate on this point. Pre-industrial levels of carbon dioxide (prior to the start of the Industrial Revolution) were about 280 parts per million by volume (ppmv), and current levels are about 370 ppmv. The concentration of CO2 in our atmosphere today, has not been exceeded in the last 420,000 years, and likely not in the last 20 million years. According to the IPCC Special Report on Emission Scenarios (SRES), by the end of the 21st century, we could expect to see carbon dioxide concentrations of anywhere from 490 to 1260 ppm (75-350% above the pre-industrial concentration).\n\nYes. Global surface temperatures have increased about 0.6°C (plus or minus 0.2°C) since the late-19th century, and about 0.4°F (0.2 to 0.3°C) over the past 25 years (the period with the most credible data). The warming has not been globally uniform. Some areas (including parts of the southeastern U.S.) have, in fact, cooled over the last century. The recent warmth has been greatest over North America and Eurasia between 40 and 70°N. Warming, assisted by the record El Niño of 1997-1998, has continued right up to the present, with 2001 being the second warmest year on record after 1998.\nLinear trends can vary greatly depending on the period over which they are computed. Temperature trends in the lower troposphere (between about 2,500 and 26,000 ft.) from 1979 to the present, the period for which Satellite Microwave Sounding Unit data exist, are small and may be unrepresentative of longer term trends and trends closer to the surface. Furthermore, there are small unresolved differences between radiosonde and satellite observations of tropospheric temperatures, though both data sources show slight warming trends. If one calculates trends beginning with the commencement of radiosonde data in the 1950s, there is a slight greater warming in the record due to increases in the 1970s. There are statistical an

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.

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.
