Several factors contribute to global climate change, and all of them have a varying degree of affect. Man-made greenhouse gases and volcanic eruptions certainly play a part of this. Personally, what I believe to be true is that the single biggest factor that determines global climate trends is activity on the sun's surface. The sun is after all where virtually 100% of our energy originates. Sunspots are areas of lower temperatures, which a period of a lot of sunspots could easily cause the Earth to receive less energy over a period of time. I don't know if this has been shown at all scientifically but it makes sense to me. Here are some other random thoughts of mine on the subject:
-It is impossible to say whether or not man-made emissions are the most significant factor in climate change, regardless of what the media and Al Gore says. It is just not good science to make that conclusion based on so little data. Clearly there is an agenda these people have other than truly trying to find the cause. Why else would so many reputable scientists jump ship?
-They like to cherry-pick data. Conveniently not mentioned is the finding that from Jan 07 to Jan 08, global temperatures actually declined, and erased the increases made from the past 100 years. Who knows if that's actually true or not, but it has to have the same validity that negative statistics have.
-Logically, how could you think that the CO2 emissions from cars and factories is a significant source of CO2 overall? This amount is dwarfed by the 4.5 billion people on the planet breathing, and not to mention the countless other animals.
-Say global warming could be controlled by man. Don't you think that increasing temperatures would actually have more benefits than cons? Milder winters would mean less energy costs in the winter, and there are many other benefits that are conveniently never mentioned. Only the negatives are mentioned by the media.
