Coming from a science background (I went to the California Institute of Tech) I have to say that this thread is a little worrisome.
If there is this much confusion and uncertainty among highly conscious people about whether global warming is happening and whether it is man-made, then we are all really in trouble
To set the record straight:
YES, global warming is happening.
* There is complete agreement in the scientific community
* There is a wealth of data that backs up this claim
* No, it's not part of the natural cycle
YES, man-made greenhouse gases are the cause.
* The science is well understood.
* The data is also available.
If you haven't already done so, please do me this favor and watch
An Inconvenient Truth. It's not political, it's a little dry, and it's the best (and most digestible) presentation of the facts that I've seen so far. Don't believe me, just keep an open mind and go rent the DVD. Thanks
