There are a lot of people who believe as you do. There is some evidence to support the idea just as there is some evidence to support the altered greenhouse effect as the culprit. Unfortunately people, including scientists like to simplify things and so accept only one thing or the other.
Most of the visual evidence supports either scenario, simply confirming global warming.
Temperatures have been rising as have CO2 levels. This does not logically imply causality or even a direct correlation of the two. They could be quite unrelated or both be the result of some other factor.
I have seen graphical representations that seem to present a link. I have also seen graphs of sunspot activity that closely match the graphs of actual temperatures over the last 130 years. In spite of the fluctuations that may be from sunspots the temperatures continue to rise.
Other representations suggest that temperatures have been slowly rising since the Maunder Minimum of sunspot activity three hundred years ago. It appears that temperatures were rising long before CO2 levels started to rise.
That doesn't let CO2 of the hook altogether it does allow us to estimate the possible contribution of CO2 though. It is actually too soon to separate the solar and CO2 effects especially since it seems likely that CO2 levels will continue to rise, probably until we run out of coal.
If we made an estimate on todays figure it would be around 2/7 CO2 and 5/7 solar. But that will likely change.

Global warming is not a natural phenomenon but greenhouse effect is. It is what we couldn't live without because it regulates the climate by trapping heat and acts like a warm-air blanket that surrounds the Earth. But too much of it becomes a problem.
Global warming is caused by the emissions of greenhouse gasses which trap heat from the sun. There are several greenhouse gases, mainly carbon dioxide, methane and nitrous oxide. Rapid human activities such as deforestation, agriculture and industrialization release these greenhouse gases excessively into the atmosphere, causing global warming. Yes, the world’s temperature has always been up and down, but human activities distort and accelerate the natural process. Therefore, global warming IS man-made.

If it was a natural phenomenon (it's not but let's leave that aside for the moment), it would still present almost all of the same problems , and it's already happened/happening.

The earth does in fact change in temperature, sometimes quiet suddenly, as it happens, given the pre-human historical pattern we SHOULD be heading slowly into an ice-age, we're not.

As a planetary civilization we are kind of married to the way things are, change things significantly - anywhere, and bad things happen.

Australia for instance used to have farmland in the lower 1/4 to 1/3 of the semi-arid desert (which could be irrigated like Northern California) in NSW and such. After the arboreal forest firestorms of the 1990's and the continuous drought since the early 90's.

Australian farmers - this year have been instructed not to plant crops to preserve water for human use and cull the bulk of their herds since the land can no longer support farming. Australians will now have to import more foodstuffs from overseas, and certainly could become a net importer of food.

North America has currently started experincing seasonal firestorms in many of the forrested regions and is experiencing significantly decreased waterfall in the "breadbasket", simply put , if the croplands of North America fail, billions of people will be affected and the economy of the US could radically alter, it things were to go the way of Australia, Where would we get our food from?

We still have to adapt to the changes in the planetary environment which will be largely to our disadvantage which include but are not limited to.

1. War - Wars have already been started or have been significantly aggrivated by environmental changes (mostly desertification and drought) causing affected populations to arm up and go after their neighbors.

2. Obviously famine-disease etc, all of these festive conditions are endemic to the human condition, but all will be seriously aggrivated by the breakdown in the ability to farm in areas once temperate and able to receive rain.

This probably will not be compensated for by increases in other areas because we farm more or less everywhere on the planet we can so while the types of crops able to be produced might change, wheat is better than corn for most purposes and wheat cannot grow when there is too much rain so increased rainfall may not be a gigantic boom to all concerned.

3. Massive climactic shifts - the ice cores from previous ice-ages indicate that when enough glacial meltwater hit's the oceanic conveyor, it shuts down - fast (in as little as 10-50 years), The glaciers of Greenland are melting rapidly and may be gone in the next 50 years but will certainly not last past the next 2 to 3 hundred.

These glaciers make temperate climate in North America and Northern Europe possible. When it has shut down in the past, North America becomes a arid to semi-arid desert up through the upper midwest and significantly colder (by about 5-10 degrees) in what would be the "next logical" breadbasket of northern Canada. This is how the cycle repeats, because snow falls decade over decade and in a thousand years or so you have a glacier covering Canada - again.

Since according to the oil industry we have no more than 20-30 years of oil left anyway, doing most all of the things that people like Al Gore suggest doing aren't just "nice", they will become vitally necessary to national survival.

None of this is wild speculation, it's all past becoming prolog stuff, it's happened before, it can happen again. Worst of all if it were a natural phenomenon, that would be just our bad luck. but it's not. We will have done it to ourselves, we're smart monkeys we're just not very smart monkeys.

It's dumb and rich guys in oil and gas paying off some sleazebag "scientist" to tell us "Nothing is wrong, this is not a problem" and "nobody has reached a consensus", and most people won't realize they've been scammed until they can't get food on the table.

It's not pretty, but it should be a useful example to future generations that lazy corporations and ignorant citizens can be a dangerous combination.

Yes. Most of the scientific community including geologists who study earth's history going back millions of years, believe that global warming is indeed a natural phenomenon. There is no evidence whatsoever that links human activity to changes in the weather. Remember that this issue is political, and it's pushed by those who want to limit the economical development of the United States.

OK, Now 50% man, 50% natural
but soon we are going to get in hot water, this is ridiclous bloddy celebs get more funding than research on global warming . Were all going to die and and all George bush can think of is war on iraq and other ways to kill more innocent beings , Why stop at destroying iraq why not the whole world if we pull oursleves togather we can save each other`s butts but if we don`t the world will go down and with it billions of innocent human beings and not to mention trillion of other animals.

The world has always warmed and cooled of it's own accord. Over long periods of time the temperature changes significantly, so much so that there's been four ice ages and four occasions when the planet has been completely free of ice. There have been occasions when temperatures have been considerably colder and warmer than they are now.

What we're seeing now is a rise in temperatures many times faster than anything that's ever before been known - 19 times as fast as they did when the last ice age ended and 182 times as they were prior to the Industrial Revolution which led to a dramatic upsurge in manmade greenhouse gas emissions

Nature is still playing a part but it's been dwarfed by the effects of human activities.

---------------

More info: 18,000 years ago the world began warming and this led to a rapid retreat of the glaciers, the period often referred to as the end of the ice age. During this glacial retreat global temperatures rose by 7 degrees Celsius in 7,500 years (0.0009 degrees C per year). After this rapid warming temperatures rose more slowly and in the period of a little over 10,000 years leading to the onset of the Industrial Revolution temps rose by a further one degree (0.0001 degrees C per year).

In recent decades temperatures have been rising by 0.0177 degrees a year - 19 times as fast as when the glaciers were retreating and 182 times as fast as the period prior to the Industrial Revolution.

I was somewhat oblivious until I saw Al Gores global warming documentary called An Inconvenient Truth, it's extremely eye opening. I think it's a bit of both, but you should watch this documentary, it's really good!

If you want to obtain provide cash for local weather study, do you believe that you'll be able to get a cheque in case you say," I want the provide, as I believe that I can end up that the figures that the present paradigm is centered upon are flawed" ? The fine environmentalist, David Bellamy, has been silenced, and refused airtime. There remains to be no confirmed causative hyperlink among the volume of Co2 within the surroundings, and an broaden in worldwide temperatures. The WWWF pics of the polar bears swimming have been taken within the Arctic summer time; while the ice cap in part melts, as they could not rise up to image within the wintry weather. The ice used to be too thick! The East-Anglian uni study figures. "Oh! The figures do not fit our expectancies. Oh good. Keep quiet. Because we all know that we're proper." When the notion, and the religion is extra principal than squarely dealing with the reputable doubts of plenty of non provide-supported scientists, technology has been superceded by means of devout zealots. As Oliver Cromwell colourfully mentioned." I pray thee, within the bowels of Christ, take into account that thou mayest be flawed."

I personally think that the free market will solve most of the global warming issues as long as governments (like my own) stop subsidizing the cost of energy.

I just bought a fuel efficient car, not because I like it (I have 2 V8's in the garge as well) but because it made economic sense to do it.

Keeping public transport public will also help, Auckland went private and it is cheaper/faster/better to drive to work there.

But I digress...

By your logic, since there have always been naturally occuring forest fires, all forest fires are natural and have never been started by human beings.

The human origins of the CURRENT global warming are established fact--and are not subject to "opinion"--yours, mine, or anyone elses.
