I believe and have seen what is happening all around the world, take a real good look around be opened minded and don't listen to the powerful money people that want you to keep on consuming what is proof to be bad for the atmosphere.
Take care

1 If global warming is a part of natural cycles why is the increase in temperature occurring so fast compared to historical records from ice cores and other sources.
2 If their is a chance it is caused by humans why don't we just change our ways because most of the stuff that causes global warming is bad for the environment in other ways via acid rain, airborne pollution and mining.
3 When the earth was warmer in the past humans were not around and therefore if it is a natural cycle why has it taken millions of years of relative stability before the rapid acceleration in temp experienced since 1970. Plus look at all the records that have been broken in the last few years such as the number of hurricanes and cyclones, floods in Asia, heat waves in Europe, droughts in Australia.
Amateurs should stop arguing about this topic and let scientists from appropriate fields do their job. If you went to the doctor and he said you had cancer you wouldn't say no i don't because my friend recons its a cold or a natural cycle because 99% of the time your friend wouldnt know what El nino was or what a stable isopope does.

No, because the Bush Administration says so. jk jk. I do think that it's happening, because the carbon in the air is so much higher than its ever been because of the population as well as our standards of living. As we grow, we have a bigger impact on the world. We have also become dependent on materials such as oil and coal that are harmful toward the environment. The top ten hottest years recorded have also been in the past thirteen years. The hurricanes are also more devistating due to increased temperatures, because a hurricane needs heat to survive, and as they pass over the Gulf of Mexico, they gain extreme amounts of power. In 2005, there was also the first hurricane recorded in the South Atlantic. There is not much evidence against global warming. Yes, there are weather patterns, but they have never corralated with the carbon emmissions at such a horrifying level. We need to start being more environmentally responsible. Energy efficient lightbulbs are a good start, and hydropower as well as windmills help.

After watching An Inconvenient Truth movie (it's about global warming), I started to believe how bad and real global warming is. Yes, it does heat and cooled itself several times and United States is pollutes the most, but if global warming keeps getting worse, there will be more storms, droughts, etc. Human thinks pretty slow (i mean in time; if someone is going to visit some other country and won't come back for a long time, you might be thinking he won't come back for 1 year to couple of decades, but if the scientists said that the volcano will erupt in a very long time period, expect it will erupt in millions of years, not 1 year to couple of decades) so some of us don't really believe how "bad" it is.
I recommend everyone to watch An Inconvenient Truth if they still don't understand how "bad" global warming is. It's a very good movie with lots of explanation, and some humors. Trust me, it's really worth it to buy a DVD.

The world has in fact warmed as warm and as rapidly before now in recent human history. There are definitely things that humans have done that may have some effect on the climate over the last few decades, but the climate is not nearly as simple and vulnerable as most scientists would assume. Currently the world is cooling, and hopefully it does continue this trend, because global cooling is much worse.

As it is currenly being reported in the media and by Al Gore it is the biggest lie going. If you do the math on predicted ocean rise you know it is just so much Barbara Steisand.
the earth may be slightly warmer right now but it is within the normal range of fluctuation. I recently heard that slight warming may be a precursor to another ice age. Man has very little if anything to do with the changes taking place

It's not a matter of belief, it's a matter of science.
Basically we know it's warming, and we've measured how much:
http://www.ncdc.noaa.gov/img/climate/research/2005/ann/global-blended-temp-pg.gif
Scientists have a good idea how the Sun and the Earth's natural cycles and volcanoes and all those natural effects change the global climate, so they've gone back and checked to see if they could be responsible for the current global warming. What they found is:
Over the past 30 years, all solar effects on the global climate have been in the direction of (slight) cooling, not warming. This is during a very rapid period of global warming.
http://news.bbc.co.uk/2/hi/uk_news/6290228.stm
http://www.pubs.royalsoc.ac.uk/media/proceedings_a/rspa20071880.pdf
So the Sun certainly isn't a large factor in the current warming. They've also looked at natural cycles, and found that we should be in the middle of a cooling period right now.
"An often-cited 1980 study by Imbrie and Imbrie determined that 'Ignoring anthropogenic and other possible sources of variation acting at frequencies higher than one cycle per 19,000 years, this model predicts that the long-term cooling trend which began some 6,000 years ago will continue for the next 23,000 years.'"
http://en.wikipedia.org/wiki/Milankovich_cycle
So it's definitely not the Earth's natural cycles. They looked at volcanoes, and found that
a) volcanoes cause more global cooling than warming, because the particles they emit block sunlight
b) humans emit over 100 times more CO2 than volcanoes annually
http://www.gaspig.com/volcano.htm
So it's certainly not due to volcanoes. Then they looked at human greenhouse gas emissions. We know how much atmospheric CO2 concentrations have increased over the past 50 years:
http://en.wikipedia.org/wiki/Image:Mauna_Loa_Carbon_Dioxide.png
And we know from isotope ratios that this increase is due entirely to human emissions from burning fossil fuels. We know how much of a greenhouse effect these gases like carbon dioxide have, and the increase we've seen is enough to have caused almost all of the warming we've seen over the past 30 years (about 80-90%). You can see a model of the various factors over the past century here:
http://en.wikipedia.org/wiki/Image:Climate_Change_Attribution.png
This is enough evidence to convince almost all climate scientists that humans are the primary cause of the current global warming.

Your question is interesting specifically because of the way it is worded.
It is not a question of "Believing".
Global Warming is a phenomenon that lends itself to scientific study. In science we perform experiments and make observations and measurements. From these activities data is collected and analyzed to look for patterns that lend themselves to predictions. Over the past 30-years climate scientists from across the globe have independently confirmed, using millions of measurements,the high correlation of the accelerating rise in atmospheric CO2 and global temperature.
Temperature is the average kinetic energy of the atoms and molecules that make up a substance. Although it seems quite small, a 1-degree increase in average atmospheric temperature means that the energy content of the atmosphere is increased tremendously. Because the atmosphere has more energy we should see more activity in the climate and this is borne out by the observations.
Rather than simply believing in Global Warming I am compelled to deduce that it is occurring and that human activity greatly contributes to the phenomenon because the myriad of observations continue to show this to be the case. If the observations produce different data and conclusions I will be compelled to deduce differently. It's as simple as that.

It's true that it's been warmer in the past, no-one is disputing that. This has happened on four occasions that we know of, each of them being millions and millions of years ago.
The difference now is that the planet is warming many times faster than has ever before been known. Scientists know why this is happening and have been predicting it for over 100 years.
Put simply - greenhouse gases retain heat, the more of them there are in the atmopshere the hotter it becomes. The concept really can be stripped down to something as simple as that, any other explanation means rewriting the laws of nature.

For the most part I believe that global warming is a natural occurrence. I do think that man may have been speeding that up a bit due to all the un-natural omissions and stuff that we have been throwing into the atmosphere. I think that stuff has been harmful, and we DO need to find new ways to generate our energy besides depleting natural resources. But I don't think that man can overcome nature. We're going to have to find ways to live WITH nature. God wanted us to be good stewards of the earth and we need to stop fighting so we devise the technology it will take for us to do that.
