"It's happening" and the effects attributable to humans burning fossil fuels is a scale though. There's very little doubt C02 does increase the holding of heat. There's also very little doubt the earth has gotten slightly warmer over the past century. Where I become skeptical is in the modeling and predictions. More heat means more evaporation means more cloud cover means less heat but clouds hold heat held in. The earth tilts slightly on it's axis. Energy output from the sun varies. There are so many interacting factors. "Butterfly effect" and all. Then you throw politics and redistribution-ism and media sensationalism on top of it all and wow what a stinky mess. Suffice it to say I personally don't think global catastrophe is imminent from C02. Not convinced at all. I lived through the ice age scare (here's Leonard Nimoy talking about it: [VIDEO] ) and the start of the global warming alarm in the late 80's (which just didn't pan out as many expected 30+ years later). So I don't trust the ability to model long term climate changes and present it in an objective and non political fashion. But I do believe humans are affecting the climate and from caution we should reduce C02 as we reasonably can without starving millions to death. It's cleaner anyway and fossil fuels are just nasty in other respects and they are limited. Am I an illiterate unscientific "denier"? An oil company shill? Nope. Just a guy who has seen nonsense hype cycles which this certainly resembles come and go

> Who still believes global warming does not exist? Nobody is denying that the weather has been warming. It's all the political hysterics and nonsense that a lot of people have issues with. And of course the "world-is-ending" chicken little craziness. > I am currently listening to audiobook of Tom Clancy's Rainbow Six (1998). It has a paragraph on global warming and trying to convince POTUS it is real. And POTUS not wanting to act on it because it would be too large economic drag on US. And if you watched Day After Tomorrow, are you going to use that as an example of the globe cooling? With every shift in weather, the media and the mindless always scream the world is ending. Our parents' generation had to worry about global cooling. "As they review the bizarre and unpredictable weather pattern of the past several years, a growing number of scientists are beginning to suspect that many seemingly contradictory meteorological fluctuations are actually part of a global climatic upheaval. However widely the weather varies from place to place and time to time, when meteorologists take an average of temperatures around the globe they find that the atmosphere has been growing gradually cooler for the past three decades. The trend shows no indication of reversing. Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age."

Is there any irony in observing the fickle preferences of man in regards to geoengineering? Perhaps our understanding is more limited than some are willing to admit. 63 years ago, there was a push to warm the arctic. In 1978, doomsayers predicted a new ice age. For all of the predictions of apocalypse, none have materialized. However, throughout history fear has been a powerful tool for motivating and manipulating the public.
