I'm undecided, on one hand it is a logical hypothesis. On the other, there are some unexplained discrepencies in the data that cannot be explained. I would suggest everyone who is truely interested in this go to the NOAA and NASA web sites, download the actual data there and form their own conclusions.

Just wanted to point out that all those who cite 'evidence' to disprove global warming have failed to include a single reference or source. Could it be that there aren't any such sources.
To someone who understands the dynamics of global warming it demonstrates how ignorant some people are that seek to disprove it. The above are good examples where EVERY piece of 'evidence' is wrong (see edit below). I wonder how many have actually read the 'Mars is Melting' report produced by NASA or understand what Solar Variation actually is rather than blithely using evidence that proves global warming as a tool to disprove it.

EDIT:
On this webpage here http://profend.com/misc/ya-gwquestion.htm I've provided detailed responses with citations to all points raised in response to this question.
To Eric (below). You did indeed include a link and I'm familiar with many of the papers referenced therein. Rather than disproving global warming the paper's authors are confirming global warming, the first line of the conclusion reads "The recent warming of the earth's surface is significantly influenced by human activity".
These educated and respected sceptics have long ago accepted global warming is reality, what they're focusing on is the role that natural events have in the overall GW dynamic - something that isn't in dispute.
They're making an important and educated contribution to the GW debate and are using real science and documented evidence. None of the arguments frequently seen on this and similar sites are even mentioned. To put it bluntly - the educated sceptics use real science, the uneductaed ones use nonsense.

Me. I know for certain that the sun causes global warming. It has been doing so for about 6 billion years. No one has measured the output of the sun for the past one million years, so there is no way to determine if the current increases in temperature are being caused by the sun alone or by man as well. The sun has been putting out more energy in the pat 20 to 30 years. Even the ice caps on Mars are shrinking.

Yes, global warming is cyclical by nature. But what most of the cynics fail to understand (or admit) is that the natural cycle of things has been disrupted because of an industrial revolution that's taken place over the past 150 years. We've become an incredibly wasteful, squandering, disposable society, and for those who don't believe that vehicle emissions, smoke-belching factories, depletion of our natural resources, eradication of rain forests, and total neglect for the delicate ecological balance within our Earth's environment aren't all causing global warming to become a more prevalent factor, they're simply blind (or ignorant) of the facts. -RKO- 04/18/07

Anybody who thinks humans are the cause of global warming are idiots. There really is no way around that.
This CURRENT warming cycle started long before humans industrialized, and has included spikes which exceed our current temperature. It really requires a special kind of moron to accept that millions of years of natural climate shift just suddenly stopped 100 years ago and humans took it all over.

if humans cause global warming. which just by exhaling
emits co2.
to solve this problem reduce the population over 50%
over the next 50 yrs.
western culture is doing their part. birth rate zero.
rest of world +3.per family.

There is too little evidence either way.
I have not yet seen a climate model that accurately relates CO2 to warming. All of them show rising temperatures linked to rising CO2 over the post war period, when in fact temperature fell for about 40 years. This is very bad for those who want to believe a human cause, but they ignore it.
However, I have yet to see a convincing natural explanation for rising temerpatures - which is also very bad.

I totally think humans did not cause global warming. Over the whole time earth has been here, it has warmed up and froze, again and again. It is just nature taking its course.

Open to debate. In my opinion the world travels in natural cycles of heating and cooling over vast time scales. When the ice age finished were humans to blame then with their carbon emissions? (What emissions?) However in my personal opinion we are merely speeding the Earths natural cycle up which obviously is not a good thing but you could argue that eventually the inevitable would happen, even if we hadn't have inhabited the Earth........

There is no evidence that the human race has had any impact on the earths climate. For every theory the environmentalists put forward in support of their claims science has shown it to be false and imposable and about as credible as their demands that raising our taxes will solve the problem
