There's a reason we talk about cycles and seasons. When levels of CO2 rise -- which plants certainly don't see as "pollution" -- it triggers natural modulating influences. Higher temperatures melt ice, which causes heavier cloud cover due to moisture, which reflects more of the sun's light back into space, which lowers the temperature. And so on.Mariani also notes the fact that Mars is experiencing global warming as well.
When CO2 levels fall too low, natural processes cause it to be released from the soil -- as seems to be happening now. Researchers from the UK's Cranfield University found that some 13 tons of carbon are being released from the soil every year, as Reuters recently reported. "Since the carbon appears to be released from soil regardless of how the soil is used, the researchers conclude that the main cause must be climate change itself. Though they could not say where all the missing carbon had gone, much of it may be entering the atmosphere as the greenhouse gases carbon dioxide and methane, which many scientists say is causing global warming." Scientists from Germany's Max-Planck Institute for Biogeochemistry wrote, "These losses thus completely offset the past technological achievements in reducing CO2 emissions, putting the UK's success in reducing greenhouse gas emissions in a different light." In other words, many Kyoto signatory nations have crippled their industry, spent vast amounts of money and caused rampant unemployment for absolutely nothing.
Science -- not junk science based on hysteria and ideology, but real science based on data and reason -- suggests that global warming is driven more by the sun than anything humans have done. A recent study by Swiss and German scientists indicates that the sun is burning hotter than it has at anytime in the past thousand years. "The Sun is in a changed state," stated Dr. Sami Solanki, the director of the Max Planck Institute for Solar System Research. "It is brighter than it was a few hundred years ago and this brightening started relatively recently -- in the last 100 to 150 years." Does that time frame sound vaguely familiar? It's about the same time the Little Ice Age began to end -- the same time that Liberals claim humans began to cause global warming. Isn't it clear that the sun is the real cause? Shouldn't we at least examine this before ruining our economy for nothing?

Anthropogenic global warming, we hardly knew ye
Joe Mariani tosses in his two cents against the notion that human activity is negatively affecting Earth's climate:
