Why do the global warming "scientists" ignore human waste heat? It is quite considerable, all dumped into env.

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.\n\nLook at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.\n(see links below)\n\nHow's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.\n\nThere has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.\n\nYes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up. \n\nJust to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.\n\nHI CO2: \nhttp://news.bbc.co.uk/1/hi/sci/tech/4467420.stm\nHOCKEY STICK: \nhttp://news.bbc.co.uk/1/hi/sci/tech/5109188.stm\nGeneral climate stuff: \nhttp://news.bbc.co.uk/1/hi/sci/tech/3897061.stm

It is clear that we are in a period of Global Warming.  The average temperatures are rising.  That is a fact.\n\nIf you mean, are we suffering from a man-made global warming, that is a tougher question.  A lot of experts have debated this and disagree.  Here in Florida, we have had two really bad hurricane seasons in a row, and a lot of people are scared that this is because of "Global Warming" but the experts at the National Oceanic and Atmospheric agency are reporting record warm temperatures and at the same time are downplaying the man-made causes by saying there is no "proof"\n\nAn interesting thing that may happen is that Europe may go through a mini ice age because of this warming.  There is an oceanic conveyor belt that helps distribute heat throughout the world.  This belt ends up in the Artic near Europe.  When the polar ice caps melt, there is an influx of fresh water that changes the salinity in the ocean up there.  This breaks that belt and so the warmth stays in the other portions of the globe.  There was a great special on this a couple of months ago on the History channel.\n\nI don't know if we are causing the Global Warming, but I do know that we are trashing our environment and we should be a lot better consumers so that our children and grand children will have a vibrant and healthy world to live in!

It is a myth thought up by the tree huggers to get money from the federal government of the USA to do studies. they had to have a reason for the grants. Over all, although it seems warmer the earth has actually warmed only about 1 degree. It is warmer in cities because of the concrete and asphalt.\n\nThey have tried to blame the depletion on fluorocarbons, but that is a out  and out lie because Mt. Pinatubo (hope that is spelled close) has put out more fluorocarbons than all the air conditioners, aerosol cans and refrigerators have combined since before WWII.\n\nAlso H.A.A.R.P. is to blame for the changes in weather. If you don't know what that is...look it up and find out.\n\nReading some of the answers given no wonder the bad guys are winning...quit believing the garbage put out by the news media and learn for yourselves. I keep giving information and sites and yet you don't look at them or try to learn...no wonder this world is going the way it is...too many young people just parrot what they hear and never check out for themselves...get with it kids because you are fast loosing your country and world! Now read below!

As partisan and insulting a statement (not even question) as that is, there are a few aspects to be addressed when discussing global warming.\n\nGlobal warming is the term used to describe how the average temperature of the planet is going up.  No one denies that the temperature is, in fact, going up.  Therefore, no one denies that global warming is a fact.\n\nHowever, according to studies of Antarctic ice, the average temperature of the planet has been rising for 6,000 years, which is well before the Industrial Revolution of 150 years ago.  This proves that global warming is not caused by man.  In that time, however, the rate of temperature rise has increased, which means that the actions of humanity probably has worsened the situation.\n\nThe critical facts about global warming are these:\n\nWhat are the effects of global warming going to be, and how can we prepare for them?  Currently, no model of global atmospheric projection has shown itself to accurately predict to any degree the general weather patterns of the Earth (such as the number and ferocity of hurricanes).  Until we come up with an accurate way of predicting the effects of global warming, preparing for them will be difficult and based upon conjectures, which are a difficult sell to taxpayers.\n\nWhat can be done to limit the effect of humanity on global warming in the future WITHOUT putting a major damper on economic growth and development, especially in developing nations?  For example, all nations could agree to stop driving vehicles that use internal combustion engines, but to do so at once would devastate the economies of many nations.  However, other options, such as diverting tax funds to subsidize the development of alternative-energy propulsion for vehicles, would accelerate the advent of such earth-friendly technology.\n\nAll in all, because of the massive stakes involved when discussing global warming (and the subsequent misinformation flying around about it), many people are confused as to the facts about it.  I was hoping to be as informative and unbiased as possible.\n\nPlease let me know what you think!

This is pretty much a dead subject since the Bush Administration ignores that there is a Global Warming problem. They wouldn't continue the program.

Hasty and uninformed.  Usually global warming is used as a political tool for lobbyists.  There is no evidence that global warming exists.  It is just a theory based on data.  Another alternative theory is that the Earth heats and cools in cycles. \n\nPersonally, regardless of which theory you believe, I still think that pollution ought to be diminished.  It seems largely responsible as a carcinogen - causing cancer.  But then again, thats just my theory based on the apparent data.

Global warming is the opposite of global cooling.  The Earth has gone through at least 3 episodes of cooling/warming.  Where I am sitting now was once under about 1000 feet of ice.  The Earth warmed up enough to melt all that ice -- and this was way before there were any cars or industry (or even people).  Global warming is NOT caused by people living their lives and producing things. People may have an effect on the rate, but we are not the CAUSE. BTW, the ozone layer hole, which expands and contracts, has no direct effect on global cooling/warming.

Global warming caused by humans is a myth.  It has been debunked by scientist after scientist.  The reason the earth is in a "warming cycle" (the temp on earth has risen 1 degree in the last 100 years..1 DEGREE) is because the sun is hotter.  \n\nThe environment is the new "religion" of the left, both in America and abroad. They don't believe in God and hate America.

"Are we destroying the earth with technology or is the earth doing business as usual"\nI suggest you track the changes scientists have found in the entire history of the earth, warming, freezing, wet and even effects of smoke from Krakatoa. Then compare what is happening now with pollution and the depletion of the ozone layer and ask the readers to make their own conclusion.

Very noble thoughts but hypocritical! Who would leave his car at home and ride a bicycle to work? Would u? The world is too entangled in the interests of different groups to let go of the facilities it has even if those facilities pollute our air. Big business clearly doesn't bother--Has there been a decrease in number of cars manufactured in the world? OK they're more energy efficient, but that doesn't solve the problem--Energy efficiency doesn't change the gases released into the atmoephere. Until now we should have developed and started mass producing a car using some other source of energy.Generatios to come will look back and definitely blame us for our inability to react fast enough to a looming danger.

Yes, it warms and cools in cycles.  I question the word "billions" but yes, it warms and cools and mankind has nothing to do with it.  It is a political power grab and someone is getting a lot of grant dollars for their "studies".

First things first,\n\nI am a geologist, and I do not believe that global warming is caused by man's activities (anthrogenic), so you will hear some of what you need for your debate.  You may find that there are many scientists who do not subscibe to the anthrogenic "theory", despite what they teach in the classroom. \n\nFirst, the Earth is in an interglacial period which we entered approximately 10,000 years ago, the end of the last Ice Age.\n\nSecond, the Earth had a dramatic cooling during historic times, starting approximately 600 to 800 CE and ending approximately in the Mid 19th Century though some researchers are placing the re-emergence of the warming closer to the end of the 19th Century.\n\nThird, although weather measurements were standardized in the Mid 19th Century with the adoption of the SI units of measurements, instrumentation and permanent data stations were slower to evolve.  In other words accuracy and precision in measurements can not be documented for most of the historic record.  \n\nOther factors complicating Global Warming:\n1). the Carbon Cycle can not be adequately quantified \n2). the computer models do not take descrepency of the Carbon Cycle into account, therefore the models are NOT calibrated (although the modeler's will vehemently deny this fact)\n3) other influences such as reduction in solar radation natural volcanism, and even yearly forest fires are ignored.\n4) ignores the fact that although some warming is taking place in the Arctic, Antarctica is exhibitinhg many areas of colder temperatures \n5)Finally my pet peeve about the increased CO2 curve shown in every debate, the famous "hockey stick"...The monitoring station on Moana Loa is on top of an active volcano, a source of naturally occuring CO2.  Until they correlate this data to any increase or decrease in the volcanic activity on Moana Loa the data are suspect.\n\n\nI hope this helps...Check out junkscience.com for more information.

I'm a conservative, and I'm also pro-environment and pro-animal rights.  But I do think that the entire "global warming crisis" has been blown out of proportion by special interests.  The scientists who speak the truth are silenced.

because it only affects the US.  Never mind we out produce everybody.  The Kyoto Protocals don't do anything for the alleged global warming.  If there is such a thing how could humans stop it?  Stop volcanoes from exploding? In school they taught us about weather cycles, that included several ice ages. In the seventies they were worried about global cooling.

You know, when my grandfather was a kid, the government and the military dreamed of controlling the weather.  Now, 70 years later, the government has long since given up on the idea of controlling the weather.  But now we have people running around screaming about global warming who are supposed "experts" in the field.  We can't control the weather and bend it to our will so now they want us to believe that we can drastically alter it by ACCIDENT?!?  What arrogance.... Michael Chrichton's book was a work of fiction but his writing was solidly researched based on actual scientific data, not by waiting till the middle of August and then claiming that since it is 105 degrees outside, it must be due to "global warming".  What a riot.  Why do you think the government refused to sign the kyoto accord?  Because of money?  Bull... it was because it could not be scientifically verified.  OK. Very sorry to have climbed up on the soapbox.

You're a fool if you don't believe in global warming.  That is happeneing and vetted by alot of scientists.\n\nNow, the cause of global warming is certainly up for discussion/debate.

the sun..... the sun is the only thing responsible for warming the earth. Dont get me wrong ...pollution and greenhouse gases also contribute. But they are not the only reason. We are in a short period of warm temperatures on earth. A small window in time. We just got out of an ice age about 12-15ooo years ago. We have had longer periods of global Ice Ages than we have of global warm periods in the last few million years.... Did u know that a violent volcano can spew enough greenhouse gas into the atmosphere to warm our atmospheric temperatures several degrees. Pollution does the same thing but on a smaller scale. This gas traps the earths heat from escaping back into space. Its like a blanket for our atmosphere. Then the earth gets warm, and creates more water vapor from the oceans. More water vapor means more clouds. More clouds mean less sunlight hitting the surface of earth, less sunlight means less heat, less heat means more ice.. and we go back into an ice age.... then the earth fixes herself, we start to get warmer.... and we go on and on.... Its been happening like that for millions of years. If it wasent for global warming we wouldnt be alive and the earth would be covered with seals, penguins, polar bears and wolly mammoths.
