Its real, despite what the naysayers are saying. Most scientists that aren't being paid by the oil production companies (including Nobel Prize winners) agree that it is real and I make it a habit not to disagree with most decisions by Nobel Prize winners.

There is such thing as global warming but who is to say whether it is do to a human influence. The earth goes through climatic changes all the time. Who is to say that the recent warm trends is due to global warming or just a warm climate period. Who knows in a year, five, or ten years we could be in a very opposite climate pattern. Also how does anyone know whether or not this very same warm period didn't occur 200 years ago or even 1000 years ago. The U.S. only has recorded weather observations back to the 1890's. That is only a hundred and twenty years of somewhat definitive data. There is no way that one can make a definite conclusion about global warming and how bad it is. Just think this earth has been around for millions of years and we have recorded weather data for 120 years of that.
Come on now. I'm finished!!!

Yes I believe the earth is getting warmer, yet the notion that humans are causing any of it is dubious and unprovable.
There have been many times in the past where the polar caps had only seasonal ice; or none at all. There were also times in geological history where the atmosphere was utterly loaded with carbon dioxide on a scale unimaginable today - the carboniferous period some 300 million years ago the atmosphere was so rich with the gas and the atmosphere so dense (there was also more oxygen) that spiders grew to the size of dogs and centipedes were ten feet long. This is also the era of 3 foot wide dragonflies.
So the earth has, in effect, been there and done that - and this warming cycle is no different and not even as dramatic as these past events.
Some say that the speed of the warming is unnatural; but in the lifecycle of this planet there are sudden events that cause near immediate effects on weather and climate. One is vulcanism - a volcano like Krakatoa erupts and plunges the earth into a sudden, if brief, cooling spell. There are also things like El Nino and sunspots. People don't realize how much influence the sun has on our weather and climate. Sunspots and their absence are known to affect climate, sometimes to extremes . Back in the 1700's there was a period of almost no sunspots and the earth went into a sort of mini ice age. Winters were extremely cold and growing season were shortened.
That said, I do believe it's best to do away with dependance on oil - not only because of middle east instability, but because one day the earth will simply run out of oil. Going "green" also is beneficial for cutting down on pollution too.
In a nutshell I believe that global warming is definately real, but that humans (we give ourselves WAY too much credit - or blame!) have little to do with it.

The thing about global warming is quite tricky. As stated earlier, much more research is needed to completely answer any questions mentioned here. In fact, the Earth has been in a state of "gloabl warming" for the last 18,000 years, so the fact that the earth is still warming is no big deal; the issue today is whether to link industrial traits to this rapid increase in temps. About CO2, its actually corrilated to temperature increase, but temperature is not controlled by the levels of CO2, so what that means is that when temps go up, the lvl's of CO2 go up, not CO2 goes up, therefore increasing temps. Another issue is the "heat-island effect". This is when temperatures were originally recorded at the surface, or near the surface. When these temps were recorded higher than normal, global warming appeared everwhere. The reasons for these readings were caused by the buildings in the urban areas, which actually retain heat better than the natural environment (which they were constructed to do, obviously). of course, once this was realised, measurements have been taken at higher altitudes. As for what I beleive, I tend to think that It is occuring, and humans have accelorated it's process, yet with modern technology, and conscience people, it can be mangaed within reason.

Global warming is real. The question is: are we to blame for it?
Since there have been fairly substantial (in human terms) warmings and coolings in the last 1000 years, it is questionable whether industrialisation is responsible for the current warming.
What side scientists and politicians take, really depends on which side their bread is buttered.
Nobody knows for sure whether the current trend is part of a natural cycle or not. Because of this uncertainty, some countries, the USA in particular, are not willing to cut back industrial processes in the fear that it would threaten their economies.
For my part, I can't see why a little bit of extra CO2 and a bit more warmth won't be beneficial. It will promote plant growth, which means we can more easily feed the burgeoning population.
True that some sea level rise will threaten some low-lying regions, but sea-level has changed many times through history. It is something populations have to deal with.
Time will tell who is right.

While belief in global warming has become "scientifically orthodox," the simple fact is that there isn't enough data at present to prove that man-made factors are having any significant long-term effect. (Anybody want to scream and rant rather than present me with cold hard facts refuting my claim? Go ahead and prove me right when I say people believe in global warming out of emotional reasons rather than sound deduction).
The greenhouse effect is a very real phenomenon (without which the earth would be locked in a permanent ice age), but further research is needed in order to determine whether manmade agents are responsible for an increase in this effect.
Short answer: needs more research.

I don't believe in it...I accept that it exists. Not only are scientists not paid by oil companies saying it, but also, here's the big thing:
It's not just one thing they see changing. It's a whole bunch of interconnected things. The temperature isn't just getting higher. Things in nature are changing because of it. For example, butterflies have shifted their ranges by 200 kilometers in North America and Europe. I read in Scientific American or Discover (this was a year ago or so) that in Britain, the babies of a plant bug (hemiptera) that often comes to Britan from Italian produce were found. The thing is that, until recently, the plant bug eggs wouldn't have survived in Britain. It used to be too cold for the Italian bug eggs to survive. Birds are migrating earlier, weather is becoming more extreme. All these things, weather, animal behavior, plant growth, and so on, come together and all point at the same thing: Global warming is real, and it's going on NOW.
The biggest pointer to its reality is this: It's happening too fast. Yes, there ARE natural cycles of warming and cooling. The problem is that this warming is going on a good deal faster than the cycles of nature. Nature works on long timescales, millenia at the very least (look at geology and evolution). This has been going on much faster than millenia. Too fast for nature, but fast enough for humans to do.

The average global temperature is rising (very slowly) and has been for thousands of years since the last ice age. Man is having a slight impact on global warming, mainly as a result of land clearing and building of large cities. A very minor contributing factor is CO2 emissions. Global warming and cooling is a regular occurance on this planet of ours.

There is global warming and it IS very serious because many species are dieing out. Not only that but if nothing is started to done now, then things will really get out of hand.

i glance at it this way. If guy is inflicting the earth to develop into warmer via each and every of the vehicle exhaust etc. it is supposedly the clarification at the back of the warming then how did the Ice Age end while there have been no automobiles to pollute the air and reason temps to upward thrust? The Earth could be getting warmer in spite of the shown fact that this is finished that interior the previous so i don't see the reason for alarm or the could want in charge every physique.
