Global warming is human caused and deserves to be a major concern when deciding American policy.

First off, it is very important to address the fact that Earth is not the only planet to be experiencing climate change in our solar system currently. In fact, many astronomers have announced that Pluto has been experiencing global warming[1], and suggested that it is a seasonal event, just like how Earth's seasons change as the various hemispheres alter their inclination to the Sun. We must remember that it is the Sun that determines our seasons, and thusly has a greater impact upon the climate than we could ever even try to achieve. In May of 2006, a report came forward[2] revealing that a massive hurricane-like storm that occurred on Jupiter may be caused by climate change occurring on the planet, which is expected to raise its temperatures by 10ï¿½C. National Geographic News reported[3] that a simultaneous rising in temperature on both Mars and Earth suggest that climate change is indeed a natural phenomenon as opposed to being man-made. The report further explains how NASA has reported that Mars' carbon dioxide ice caps have been melting for a few years now. Sound familiar? An astronomical observatory in Russia declared that, "the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun". They further point out that both Mars and Earth have, throughout their histories, experienced periodic ice ages as climate changes in a continuous fashion. NASA has also been observing massive storms on Saturn,[4] which indicate a climate change occurring on that planet as well. NASA's Hubble Space Telescope has also been recording massive climate changes on Neptune's largest moon, Triton[5]. Triton, whose surface was once made up of frozen nitrogen, is now turning into gas. The Associated Press has reported that satellites that measure the temperature of sunlight have been recording an increase in the sun's temperature[6], meaning that the sun itself is warming up. Even the London Telegraph reported in 2004 that global warming was due to the sun being hotter[7] than it has ever been in the past 1,000 years. They cited this information from research conducted by German and Swiss scientists who claim that it is increasing radiation from the sun that is resulting in our current climate change. 'An Inconvenient Truth' very convincing of its hypothesis that global warming is a man-made phenomenon that has the potential to kill us all and end humanity. Nonetheless, Al Gore is not a climatologist, meteorologist, astronomer, or scientist of any kind; he is a politician. As Al Gore's popularity grows the issue is spiralling into a massive push for quick action and stifled debate, forcing many scientists to speak out and challenge the political status quo. A group of scientists recently stated that the research behind Al Gore's film and in fact, the concept of greenhouse gases causing global warming, is "a sham".[8] In Gore's movie, he presented evidence that was found in the research done on ice core samples from Antarctica, which he claimed is proof for the theory of CO2 being the cause of rising temperatures. However,warmer periods of the Earth's history came around 800 years before rises in carbon dioxide levels, therefore a rise in CO2 follows a rise in temperature, rather than increasing temperature following rising CO2 emissions.
