I think people are silly to believe it's not happening at all, because it certainly is.
Argument regarding how it's happening is certainly valid. Some people believe it's a natural cycle and we have very little effect on the climate, others believe that we have a huge effect on the climate. Of course there are those who believe it's a mixture of two.
Personally I really don't know. I know a volcano can produce more 'bad' in a couple days than humans can do in years and those have been around since the planet has formed. My guess? We are probably accelerating the process but I don't think it's to such a massive extent that some are making it out to be.

Human activities, responsible for a projected 35 billion metric tons (gigatons) of CO2 emissions in 2010 (Friedlingstein et al., 2010), release an amount of CO2 that dwarfs the annual CO2 emissions of all the world’s degassing subaerial and submarine volcanoes (Gerlach, 2011).
The published estimates of the global CO2 emission rate for all degassing subaerial (on land) and submarine volcanoes lie in a range from 0.13 gigaton to 0.44 gigaton per year (Gerlach, 1991; Varekamp et al., 1992; Allard, 1992; Sano and Williams, 1996; Marty and Tolstikhin, 1998). The preferred global estimates of the authors of these studies range from about 0.15 to 0.26 gigaton per year. The 35-gigaton projected anthropogenic CO2 emission for 2010 is about 80 to 270 times larger than the respective maximum and minimum annual global volcanic CO2 emission estimates. It is 135 times larger than the highest preferred global volcanic CO2 estimate of 0.26 gigaton per year (Marty and Tolstikhin, 1998).

Wiping is Fun! ™
We may contribute to an extent that we worsen the situation so much, that if natural disasters of larger magnitude happen, there's no easy recovery from it anymore, if at all.
We don't know.
What we do know is, that we do pollute the atmosphere more than it's ever been polluted before any disastrous climate change, as an ice age for example.
and of everyone of those places nearly all of em have people from those same locations that disagree with the findings. as a group they may say one thing but that doesn't mean its a universal decision by everyone there just a greater majority who cant prove without a doubt their findings.. both sides are quoting flawed and suspect data that fits their side of the story while ignoring or dismissing the other sides data... hence no one agrees.
2 years is such an small period in climatology that cant be used for anything. Millons of things could have caused a couple of inches less of snow.
Global warming exists, the problem is, how big is the impact really? and how much does human contribute to it?
Ecologist always exagerate (for example, the ozone hole was not such a big problem like ecologist claimed), and anti ecologist always minimize.
Unbiased opinions are rare.
oh you haven't offended me someone quoted above that theory's are not guesses.. yet that's exactly what they are.. best guess based on observation using scientific processes and will remain a given or proven theory until such time as it can be proven wrong or adjusted to new findings.. (aka best guess using proven data)
Sorry didnt realize i was coming across with an attitude not my intentions.
Find me the scientists from these organizations who disagree. And then tell me how qualified you are to accept and analyze the evidence presented and rejected by the vast majority of scientists. In fact, you've made quite a few claims in one paragraph. None of which are actually backed up by facts or sources.

So the theory that germs make us sick or that our bodies are composed of trillions of individual cells are just guesses?
Hm.. then how come when I listen, read, or watch scientists talking about the Suns ultimate fate, which is undeniably happening, that they never refer to the Earth of being unpopulated? They always say that all life on Earth will extinct right then, when the sun starts to become a red giant. Once it expands the heat on Earth will climb as well, and eventually extinct all water and life.
Not before that. And we know how we get O2... We only need to plant up forests to produce it. If we'd ever run low, we make O2. We're already smart enough nowadays, let alone what we will be able to do in 200+ million years. If we are still around by then.
my source is the debate about the entire thing. if it was a universal truth then their would be no denying it. but since one side wants to point at one set of data and say this is the proof.. then other side says hold on.. this is the truth.. it basically tell you that both sides are cherry picking data and refusing to acknowledge the others if this wasn't so .. we wouldn't be having this debate. the only truth is temperatures change. the debate is whats changing it.. i don't need a science degree to have at least a basic understanding of whats going on. hell we cant even tell you if eggs are good or bad for you.. wait 10 years and they will change their minds again ...
Causes and timing of future biosphere extinction
Over the next few hundred million years, the sun's increasing luminosity will begin to disrupt the carbonate-silicate cycle and result in the level of atmospheric CO2 dropping. Within 800 million years, CO2 levels will be too low to support any form of photosynthesis and multicellular life will go extinct. At 1.3 billion years, single-celled eucaryotes can no longer survive. At 1.6 billion years, single-celled procaryotes, the last form of life extant on earth, will go extinct, again due to falling CO2 levels.
Naturally, all this is barring some form of intelligent life intervening to maintain habitable conditions on the planet. If us or some other sufficiently technologically advanced lifeform is around at the time and wants to do something about this process, all bets are off.

This might be the second year in a row with record low snowfalls here in western PA. I raise my drink in hoping this is a trend it would saving me having to move when i retire.
