A topic worthy of the Myth Busters, Global warming, despite what the people have presented as information, was not caused by humans. Global warming is a product of human anxiety, and is very misunderstood.
Ice cores taken from Antarctica, and other icy regions, can give us a clue on what the past was like. The results found that only is the last 500 years, has the overall climate been fluctuating. Cars and so called "greenhouse gas" producing industries have only been around for the last 80 years or so.
Data for temperatures is very inconsistent, and not accurate, but people are still choosing to rely on it. Lets step back a few years in school, and learn about how to conduct a proper experiment. There are two variables: the Independent, the variable you control, and the Dependent, the variable that changes as result of the experiment. You can only have one independent variable, or your dependent variable will be affected. In this situation, the Independent variable is Location of temperature collection. While the dependent is the temperature value. Only a second independent variable was overlooked and ignored: the city. Many of these temperature readings were taken in the city, where it is always five to even fifteen degree warmer. If they are measuring the temperature of the earth, surly the whole earth isn't covered in cities. The temperature is raising, but not to the extent in which scientists are wanting you to believe.
Pollution is bad for the environment, everyone is aware of that. The most dominate of the gases that are released is CO2, or Carbon Dioxide, or what we exhale. On the other hand, trees and other plants require this to survive, and they give out, conveniently, O2, oxygen. Climate change is what is causing the excess of C02. The C02 went up, due to a cycle: C02 makes the climate generally hotter, which melts the ice. As ice melts, its the C02 trapped in the ice will be released, and more heat is generated. This is a natural earth cycle.
This earth has received a tough time, its ten billion years of existence. The climate has changed in the past, and regardless of human presence, it will continue to change. We as humans have been recording data on climate from the 20th century. How can we be sure that this is all humans' fault. We can't. Ice ages have been happening, and between them, a period of warmth. Its a natural earth cycle.
How we can prevent "global warming" is beyond the capabilities of todays sciences. They are literally placing gimmicks to get people to think that they are a good company doing their part to help with this cause. Its not bad to change your light bulbs, it save you money, and fossil fuels aren't going to be around for ever. The future is solar energy, wind energy, and water energy. Solar provide the most potential to produce the most power. The sun produces more energy every minute than we as humans have consumed though out the time we have walked this earth. Thats is free energy hitting this planet every day, and it will be there for billions of years to come. We just have to harness that. Do your lawn a favor, and plant a tree. It looks good, and you can say you helped.
In conclusion, Humans are not responsible for global warming, but we can do the environment and our selves a favor. Don't give into cheap gimmicks that companies place, go plant a tree. It costs nothing, just ask the city, and they will tell you where to get one. Make this world full of life, be independent of influence of the government, and so called data. Only you can make the right choice.

Yes I like what you had to say. No1 can you use a 100 years and say because the average temp is going up there for it must GW. It takes thousands and thousands of years of temp evidence.

Otherwise the ca$h stops coming to them.
Ahh, yes. Thank you for that. The government really does manipulate a lot, what else is new, and the whole global warming thing has really become a gimmick, and a scam. In my opinion.

You may want to reexamine these so called "facts". http://volcanoes.usgs.gov/Hazards/What/VolGas/volgas.html "Comparison of CO2 emissions from volcanoes vs. human activities. Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1999, 1991). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 27 billion tonnes per year (30 billion tons) [ ( Marland, et al., 2006) - The reference gives the amount of released carbon (C), rather than CO2, through 2003.].Human activities release more than 130 times the amount of CO2 emitted by volcanoes--the equivalent of more than 8,000 additional volcanoes like Kilauea (Kilauea emits about 3.3 million tonnes/year)! (Gerlach et. al., 2002)" My source is the official United States Geological Survey site as seen in the link. Where did you get your information from?
My information, as strange as it my seem, a past science teacher a few years ago. Considering he was a chemistry and Earth science teacher, I didn't doubt his expertise. I am unsure where he received his data. I will look into this immediately.
Void, you must remember that volcano’s have a cooling affect too. The thick clouds of ash they emit block the sun. These ash clouds are thicker then rain clouds. Also remember that volcanoes have been erupting and spewing carbon dioxide for millions and millions of years.
The amount of sulfur dioxide volcanoes put out is not enough to counterbalance the added contributions of carbon dioxide produced by people. As the US geological survey stated, our activities are like the equivalent of adding 8000 more Kilauea's, which is the most active volcano on the planet. Humanity has been a major factor in the earth's climate for a while now.
wow finally, a thread with a normal take on global warming... it seems to be a manipulative fear tactic sometimes. i wish there was a way to be more exact about the whole thing

Well said, I can't find any faults in your writtings.

Actually, the average temperature has been going down since 1998...
If you do the math, CO2 can't have any significant impact on global temperature at it's current levels. In fact to have any measurable effect it would have to exist at lethal (or nearly lethal) levels.
The fact the the heat produced by the sun is not enough on its own to explain the increase, doesn't prove that it's increased activity didn't generate more high energy particles in the upper atmosphere, thicken the ozone layer, or deflect cosmic particles associated with increased cloud formation. Information from top scientists in their respective fields suggests with these additional effects, not only did the sun play a larger role than first believed; but, in fact, it can be safely blamed for nearly all (if not all) of the increase.
The current lull in global warming directly corresponds with the current lull in solar activity.
No other model matches up so closely.
One of the models that matches worst is CO2 trending.
A common misconception amongst the general public is that temperatures are rapidly increasing. This is only with some of the surface data, and it is selected surface data. In fact, much of the surface data that is collected is around urban areas or areas, which have had significant land use changes. And, that data is contaminated. Most cities of the world are hotter than their surrounding environment. This has nothing to do with CO2 but has everything to do with land use. On the other hand, satellites provide comprehensive coverage of the earth 24/7. Satellite data from the last 29 years has demonstrated that there has been an almost imperceptible rise in temperature in the northern hemisphere from 1980 to 2002 and a slight decline from 2002 through 2007.
Myth #2 Global Warming will cause an increase in Severe Weather
It has been said that global warming will cause more severe weather patterns. This is simply not true. All weather patterns on our planet are caused by the differences between atmospheric high and low pressures. All air flows from high pressure to low pressure. Our planet has three atmospheric circulations in each hemisphere caused by high and low air pressures (e.g., Polar Cells, Ferrel Cells, and Hadley Cells). The Polar Cells are circulation patterns from polar highs located at the North and South Poles to subpolar lows located at approximately 60o north and south latitude. The Ferrel Cells are circulation patterns from subtropical highs located at approximately 30o north and south latitude to subpolar lows. And, the Hadley Cells are circulation patterns from subtropical highs to equatorial lows located at the Equator. During periods of global warming, the Polar Regions warm twice as much as the Equatorial Regions. This decreases the differences between atmospheric high and low pressures. This decrease will decrease the atmospheric circulations. This will decrease the severity of weather patterns. History shows that storm frequency and intensity is greatest during colder periods. The extreme weather of the Little Ice Age (LIA) provides a good example. During the LIA, there were more cyclones when the atmosphere was colder.
Myth #3 Global Warming will cause more Severe Droughts and Floods
It has been said that global warming will cause more severe droughts and floods. This is simply not true. Warmer air can hold more moisture without cloud formation causing an increase in humid, sunny days and a decrease in droughts. Cold fronts force moisture out of warm air masses. During periods of global warming, the intensity of cold fronts will decrease. This will decrease flooding. Global warming will create ideal growing conditions. History shows that during the Medieval Warm Period (MWP), vineyards flourished in northern England and the Vikings grew wheat and barley in Greenland. During the LIA, Europe experienced widespread famine because of continuous cloud cover and cooler temperatures. The greater risk to the human race is not global warming; it is global cooling.
Myth #4 Carbon Dioxide causes Global Warming
Water vapor comprises 95% of all greenhouse gases. Carbon dioxide (CO2) is a very minor greenhouse gas. Science is about testing a hypothesis. The real question is whether human contribution of CO2 to the atmosphere causes global warming (i.e., Theory of Man-Made Global Warming), and it needs to be tested. The Modern Warming Period started 160 years ago. During this time, the earth's surface temperature has increased 0.74o Celsius. During this time, temperatures have fluctuated greatly while CO2 has increased steadily. A recent report issued by NASA's Goddard Institute for Space Studies recognizes 1934 as the hottest year in U.S. history (e.g., top 10 ranking of hottest years in U.S. history: 1934, 1998, 1921, 2006, 1931, 1999, 1953, 1990, 1938 and 1939). Global records show that between 1929 and 1939, which was a period of global depression (i.e., The Great Depression,), human contribution of CO2 decreased dramatically while global temperatures increased. Between 1940 and 1975, which is called the "Post War Economic Boom," temperatures in theory, should have increased; however, they decreased for 35 years, while human contribution of CO2 increased significantly. The first test of the Theory of Man-Made Global Warming has failed. Satellite records show that since 1998, the global temperatures have stayed static or have declined slightly. Over the last 8 years, CO2 has increased 4% (i.e., 14 parts per million). The hypothesis predicts that global warming would occur. It hasn't. The second test has failed. The third test is in glacial ice cores. Through glacial core sampling, scientists have been able to liberate the earth's atmosphere from Antarctica and Greenland as far back as 400,000 years. They have found that the change in CO2 lags behind the change in temperature by 800 years. This proves that CO2 does not drive the change in temperature. Instead, temperature drives the change in CO2 in the earth's atmosphere. The current increase in CO2 appears to be caused by the Medieval Warm Period. The third test has failed the hypothesis. The Theory of Man-Made Global Warming has been tested, and it has failed.
Myth #5 An increase in Carbon Dioxide significantly increases the Greenhouse Effect and threatens the Human Race
Carbon dioxide's contribution to the Greenhouse Effect is logarithmic, which means that each doubling of CO2 will have the same impact, and hence, each additional unit of CO2 will have less impact than its predecessor. Doubling causes about a 2% perturbation to the radiation budget (i.e., 2% change in the Greenhouse Effect). Currently, the atmosphere holds CO2 at 380 parts per million (ppm). Scientists have determined that before human contribution of CO2, the highest concentration of CO2 in the last 650,000 years was 300 ppm. This is a 27% increase. However, in a geological time frame, there is nothing special about 650,000 years. During the Jurassic Period (199 – 145 million years ago) and the Cretaceous Period (145 – 65 million years ago) the concentration of CO2 was 10 times greater than it is today. During the Tertiary Period (65 – 1.8 million years ago) CO2 was 2000 ppm. Scientists have estimated that the 27% increase in CO2 has increased crop yield by 16%, for free. Hence, an increase in CO2 has little risk to the human race and great advantage for a growing global population. The greater risk is a decrease in CO2.
Myth #6 Trees remove CO2 from the Atmosphere
Plants use carbon dioxide to grow. Trees temporarily store carbon from CO2 during the photosynthesis process. Oxygen (O2) is the waste product of the photosynthesis process. Leaves store carbon for the shortest period of time. As leaves fall to the forest floor and decay, the carbon combines with oxygen and returns to the atmosphere as CO2. The tree body masses (e.g., trunk and branches) store carbon during the life of the tree. As the tree dies and decays, the carbon combines with oxygen and returns to the atmosphere as CO2. A small percentage of the carbon remains on the forest floor as soil carbon. Because plant life is perpetual around the world, plants neither extract nor contribute CO2 into the biogeochemical cycle (i.e., Global Ecosystem). It has been said that we should not cut down our trees because trees extract CO2 from the atmosphere. Wood products (e.g., construction materials or furniture) permanently store carbon, so long as we do not burn the wood products or place the wood products in a landfill; therefore, the harvesting of trees and the production of wood products permanently reduces CO2, so long as we plant a new tree crop when the mature tree crop is harvested.
Myth #7 There is a Consensus among Scientists
Scientists do not vote on scientific issues; however, there can be a widely accepted scientific position. The Theory of Man-Made Global Warming is not one of them. The Oregon Petition is a petition opposed to the Kyoto Protocol, organized by the Oregon Institute of Science and Medicine between 1999 and 2001, shortly before the United States was expected to ratify the protocol. Professor Frederick Seitz, a past President of the National Academy of Science, wrote a cover letter endorsing the petition. The Oregon Petition was the third, and by far the largest, of five prominent efforts intended to show that a "scientific consensus" does not exist on the subject of global warming. The petition includes the signatures of 17,800 scientists. Scientists, by their nature, are skeptical, not political; however, more and more scientists are realizing that they must speak out and risk their funding because the global warming alarmists are threatening western civilization. Mainstream media has censored these scientists because their climate forecasts do not have apocalyptic outcomes. The petition has been circulated again in October 2007. Stay tuned for the outcome.
Myth #8 Sea Levels will rise 20 Feet and Polar Bears will become Extinct by 2030
It has been said the man-made global warming will cause sea levels to rise 20 feet and polar bears to become extinct by 2030. This is not only, not true, but it is absurd. Scientists have estimated that, if all of the glaciers in Greenland and Antarctica melted, sea levels would rise one hundred meters. Scientists have also estimated that the temperature of the earth would have to increase 10o Celsius for this to happen because East Antarctica is simply that cold. Furthermore, there are no scientists that believe man-made global warming will cause this 10o increase. East Antarctica holds 80% of all glacial ice. This may sound like a contradiction, however, but during periods of global warming, the glaciers in East Antarctica grow. This is because of the increase in global evaporation and humidity. The current increase in sea level is caused by thermal expansion. Thermal expansion of the oceans has increased sea level by 7 inches in the last century. This is expected to continue at the same rate during the next century, so long as the global temperatures continue to increase.
During the Holocene Climate Optimum, 5000 years ago, the earth's temperature was 2o to 3o Celsius warmer than it is today. Obviously, polar bears adapted to this climate change. They are with us today.
Water vapor comprises 95% of all greenhouse gases. Carbon dioxide (CO2) is a very minor greenhouse gas.
This is not at all true.
Even though carbon dioxide is a very minor %(380 ppm) of the atmosphere by volume it is the second largest absorber of radiation in the atmosphere. Second only to water vapor.
If you were talking about water vapor your claims of complexity and uncertainty might have some basis. However, carbon dioxide is distributed nearly uniformly world wide from sea level to 100,000 ft. It is a well understood and easily modeled. More carbon dioxide in the atmosphere absorbs more infrared radiation coming in to the earth's surface and leaving.
Myth #2 Global Warming will cause an increase in Severe Weather
It has been said that global warming will cause more severe weather patterns. This is simply not true. All weather patterns on our planet are caused by the differences between atmospheric high and low pressures. All air flows from high pressure to low pressure.
This is ignoring the fact that high pressure is caused by the expansion of gases from heat energy. Tropical storms, and hurricanes form in and along the equator because of the heat energy the Earth receives at the equator. It is this heat energy, along with the Earth's spin that drive our weather.
When debating whether Global Warming is man-made or from a natural warming cycle keep this thought in mind. Man's activities could be accelerating the process. Also keep in mind that this is a process that feeds upon itself... less ice reflecting sunlight means warmer air, more melting ice, etc. Man's activities may not be contributing very much, but with the 'snowballing' effects this process can have... it might not take much to push things a lot further, faster.
Dr. Bob Carter did one of the better anti-man made global warming speeches I have ever heard. He shows using empirical evidence that all of the claims of the warmers have no basis in fact. That is: It is the warmest ever, temperature are rising faster than ever, polar bears will die, and several others. Here is the lin:
Ice cores taken from Antarctica, and other icy regions, can give us a clue on what the past was like. The results found that only is the last 500 years, has the overall climate been fluctuating. Cars and so called "greenhouse gas" producing industries have only been around for the last 80 years or so.
Historically it has been proven that people die. There is a cycle of life and then birth that exists in humans, and in all living creatures for that matter. This fact though is not proof, however, that bullets (which have only been around for a few hundred years) are not the cause of people dying when they get shot.
How ridiculous does that sound?
Let me explain briefly why this is bad science. The scientists who determined that CFCs and vehicle emissions are causing global warming did not come to this realization by looking at history. Just like we didn't prove the existence of gravity or mass by saying that things always fall and are heavy.
The gases that we release are damaging the portion of our ozone layer that filters out the UV radiation. Without this layer our planet would bake. The facts about the current temperature of our planet are irrelevant. We physically know that these gases deteriorate this vital layer of our stratosphere and we physically know what the additional UV radiation that is let through will do to life on this planet.
Just like we physically know that a bullet will damage a heart and kill a human we know that these gases will damage that layer of our stratosphere and thus increase the amount of UV radiation let through. Forget about the temperature increase. Up until the point that the bullet hits the heart we don't deny that when it DOES HIT that the person will die.
Just because you haven't seen this bullet hit doesn't mean that it won't.
toletcleaner: "Actually, the average temperature has been going down since 1998..."
The temperature went down in '99 and '00. It then spiked back up and is now at a record high. I'm not sure how anyone can say that we aren't causing global warming. There is so much ont his topic that it is seemingly impossible to dispute it.
I just can't stand to read anymore of these posts. It is unbelievable how ignorant some people are. What's more, I cannot believe the people who bring religion to the table. I am pretty sure no one has done that here, but I have heard a lot of religious fanatics use that in their reasoning. First one must prove that god is real. It's just baffling.
