Ever notice how climate change deniers always use the same pseudoscientific arguments ["Scientist: Carbon Dioxide Doesn't Cause Global Warming,"]? That's why most of them are so easy to refute. The idea that other planets in the solar system are also warming because of some common mechanism, and this means we are not responsible for global warming of Earth, is a crock. The other planets have completely separate issues, and some of them are warming for completely different reasons. There is no solar system-wide mechanism that can explain the warming of Earth.

Why not show the increase in solar activity matching the temperature increases instead of just asserting that such increases have caused global warming? Have the surface temperatures of any other planets in the solar system shown any temperature increases? This argument is full of holes.

One of the problems with this type of [global warming] discussion is the lack of scientific rigor. People (and the author of the article) throw around the word "studies," as in "armed with studies," without providing a single reference to anything published in a peer reviewed journal. The "studies" mentioned may well have been published in reputable journals and subjected to critical evaluation, but we have no way of knowing without a proper citation. Without such documentation this is just another example of "he said, she said" and is essentially a waste of time.

Even though higher levels of CO2 can act as a plant fertilizer under some conditions, scientists now think that the "CO2 fertilization" effect on crops has been overstated; in natural ecosystems, the fertilization effect can diminish after a few years as plants acclimate. Furthermore, increased CO2 may benefit undesirable, weedy species more than desirable species. Higher levels of CO2 have already caused ocean acidification, and scientists are warning of potentially devastating effects on marine life and fisheries. Moreover, higher levels of regional ozone (smog), a result of warmer temperatures, could worsen respiratory illnesses. Less developed countries and natural ecosystems may not have the capacity to adapt.

Ever wonder why, with such a controversial issue, the overall public never is exposed to a serious debate on this subject? I have seen challenges offered by many scientists such as this gentleman, but nothing ever materializes. Anyone have any suggestions as to how this might happen or who may sponsor such an endeavor? I'm not a scientist, politician, or funded special interest, only someone who would love to see some honest dialogue.
