• Yes, that small amount can change the climate. And volcanic eruptions actually decrease global warming a bit, because of the dust.

  Also see the data below. Al Gore has nothing to do with the science.
  
  The Mauna Loa data is used because it%26#039;s actually the %26quot;cleanest%26quot; data available. unaffected by things like volcanic eruptions. Look at it here. See any %26quot;spikes%26quot; from volcanic eruptions in the last 50 years? And there are other measured locations, which say the same thing.

  The little squiggles are nature doing its%26#039; thing. CO2 falls a bit during summer when plants are active, and rises during the winter. The huge increase is us, burning fossil fuels (in addition to the shape of the graph, the increase numerically matches the increase in fossil fuel use). The scientists can actually show that the increased CO2 in the air comes from burning fossil fuels (not volcanoes) by using %26quot;isotopic ratios%26quot; to identify that particular CO2. The natural carbon cycle buried carbon in fossil fuels over a very long time, little bit by little bit. We dig them up and burn them, real fast. That%26#039;s a problem.
  
  Man is upsetting the balance of nature. We need to fix that. This is a collection of global temperatures collected by NASA that shows a general cooling trend especially around the polar ice caps. So assuming the earth is warming what could be causing it, the sun. Look at this graph also put out by NASA: http://science.nasa.gov/headlines/y2003/... it shows that the intensity of the sun is directly correlated to global temperatures and recent studies have shown that the sun is now warming than ever before, coincidence? I think not. Also consider that the other planets in our solar system, Mars in particular, are also warming: http://news.nationalgeographic.com/news/...
  You have to keep in mind that the earth goes through natural cycles of warming and cooling, take for example the ice age and later warming of the earth enough to melt the ice.
  Advocates of global warming will try and post evidence but the fact is most evidence for global warming comes in the form of general statements like “think of your children/grandchildren” that try to guilt you into agreeing with them. These ads are devoid of scientific proof and seek to toy with your conscience. Every once in a while you will see a graph submitted as evidence mostly from http://www.ipcc.ch/. Take a look for yourself, I search in vain for proof of global warming on this site, sure there are dozens of graphs showing the same data: CO2 rising along with global temperatures but where are the graphs for other greenhouse gases that make up a greater percentage of our atmosphere and are put out naturally, or graphs showing the percentage of greenhouse gases put out by humans verses the gases put out by natural sources. These graphs are not included because they disprove the theory of man made global warming. The IPCC has had a questionable past, it has published a deliberately falsified graph, the so called hockey stick graph, which left out a period of warming during the 1400’s. This warming period in the 1400’s was more dramatic than what we are seeing today, and it took place long before humans industrialized. This falsification was proven and a reprint of the graph appeared in the journal Nature. You may have seen claims that there is a scientific consensus on global warming like this one: http://www.sciencemag.org/cgi/content/fu... this is an absolute lie, do you need proof? Here http://www.oism.org/pproject/s33p36.htm the signatures of over 17,000 scientists who disagree with the theory of man made global warming (check out the report on this site it does an excellent job of disproving global warming). You may have also seen reports about ice cores supposedly proving global warming, this is not true. Here is the truth about ice cores http://www.john-daly.com/zjiceco2.htm.
  You may have the question why anyone would support this obviously false theory, the answer is money. Average people with no scientific background are being converted to the global warming crowd by the dozens due to the repression of evidence against global warming. This mass of people is the reason why notable people are jumping on the global warming bandwagon. Politicians are supporting global warming for votes, scientists are joining for media time and grants, and CEO’s are pledging their allegiance to gain customers who want to shop where the environment is being supported.
  You may also wonder why I care, you may think we can only help the environment if we agree with global warming what’s wrong with that? I want to distinguish between global warming and helping the environment. I have no problem with environmentalist causes, in fact I support them, but global warming is taking this idea to the extreme. If you were to follow the guidelines set forth by people like Al Gore your lifestyle would be, these people want to tell you what light bulbs to use. The main reason however is money, why waste millions on studying global warming when we could be rebuilding third world countries and helping the poor. Global warming is a fear tactic used to get your money and your vote by unscrupulous members of society. Hopefully this will just fade away like the global cooling scare which was brought upon us in the 1970’s by the same sort of people using the same tactics. A last link http://www.worldclimatereport.com/ possibly the best resource for answering many of the questions raised by global warming. I urge anyone who believes in man-made global warming to look into some of the resources I have presented. Do not sacrifice your money, time, vote, and conscience to the greedy members of society who are blinding you to the truth for their own greed.
