The American government should take an active role in stopping climate change

Yes I did read your link (http://www.epa.gov...). I read the way the EPA stated "As with any field of scientific study, there are uncertainties associated with the science of climate change." I then further read under the category of "What's Not Certain" the EPA states it is not certain about "Determining the relative contribution to climate change of human activities and natural causes." I surely do not want to go back and forth on this point, but the EPA article that you continue referring to specifically states that it is unknown what contributions the human activity has to climate change. Furthermore, the EPA's research is under suspicion anyway. There are two EPA workers who are highly critical of the EPA's memo on carbon gas. The are critical of both the substances of and the process behind the agency's proposed findings. (http://www.washingtontimes.com...) Additionally, in November of 2009, over 1,000 emails and more than 2,000 documents from the Climate Research Unit of the University of East Anglia were posted on the internet. The emails show how scientists have been altering climate date and hiding information which proves global warming caused by man to be false. These emails included some from American Scientist John Holdren, a top adviser to the president and he wrote that scientists who opposed the theories of climate change were "amateurs." He referred to using a "trick" that could be used to "hide and decline" temperature figures. Yet another mentioned how he was bothered to release date that could challenge climate change. (http://climategateemail.com...) (http://www.eastangliaemails.com...) In Terms of the NASA link you posted, yes I agree they said there was record melting in 2008. This is a major point that needs to be discussed. We are talking about an average over a long period of time to determine warming. Everyone would agree that one hour or one day of higher than normal temperatures does not constitute as a long enough time to establish global warming. For some reason, global warming supporters find a year or two or three to be sufficient enough to produce a trend of warmth. The EPA report you continue to quote says that it is uncertain in "Projecting future greenhouse emissions and how the climate system will respond within a narrow range." If your coveted EPA cannot project future climate changes, how can you? They continue to explain they aren't certain about "Improving understanding of natural climatic variations, changes in the sun's energy, land-use changes, the warming or cooling effects of pollutant aerosols, and the impacts of changing humidity and cloud cover." There are major scandals around covering up and hiding evidence that global warming does not exist. There are questions of the EPA suppressing evidence of their finding. The EPA even admits that it is unclear as to how the human race effects climate change. I must defer back to you yet again after you read all this compelling evidence and explain that the burden or proof is yours to prove and without it, American Only regulations cannot be expected. I didn't expect to have to continue showing all this information on how global warming is yet to be proven and how your EPA records are more under question and uncertain than your statements represent. As we all know, the earth has been warming and cooling since its existence. There was an Ice Age about 22,000 years ago, then the earth warmed for a bit and started to cool again for the Little Ice Age which began warming again around 1680. There was no proof or even reason to believe the earth was cooling and heating for all those years due to carbon gases from humans. (http://canadafreepress.com...) This is where the "Hockey Stick" graph makes its entrance, around 1998. For those who are not familiar with this, it is a climate graph which is one of the initial pieces of information to start the global warming hysteria. This graph mapped out a zero increase in temperature over the past 1,000 years with a sudden spike starting in the 20th century. The research which produced this used tree ring data for the first 1,000 years of its study and then added modern temperature date for the 20th century. These tree rings were hand picked and often discarded if they did not conform to the uniformity as the others did. A dendroclimatologist (one who studies climate using tree rings) told the US Congressional Committee that, "...this does not mean that one could not improve a chronology by reducing the number of series used if the purpose of removing samples is to enhance a desired signal. The ability to pick and choose which samples to use is an advantage unique to dendroclimatology." This 'hand picking' of evidence to prove climate stability and then a large spike in change raised many questions across the scientific community. (http://canadafreepress.com...) The hockey stick was eventually unmasked by one of the most basic forms of scientific testing we know today; the reproducibility test. Steve McIntyre and Ross McKitrick attempted to reproduce this hockey stick and were unable to do so. They even requested date and formulas from Mann (the person who came up with the hockey stick in 1998) and he would not disclose the codes and formulas he used to achieve his results. This raised even more suspicion since the hockey stick was published work and the methods as to how the results were found were not being disclosed. (http://canadafreepress.com...) The US National Academy of Sciences appointed a committee to investigate this matter between McIntyre/McKitrick and Mann. Ultimately, they found in favor of McIntyre and McKitrick. They explained that they tried to reproduce the date themselves and while they could not reproduce the hockey stick Mann has suggested, they were able to reproduce the findings of McIntyre and McKitrick. (http://canadafreepress.com...) To date, Mann still refuses to disclose his formula and codes; very continent for someone who's data is the reason we have this global warming debate today.
