Ramen,
I would suggest current science technology lacks the ability to accurately measure and quantify all of the data necessary to produce a scientific model that accurately forecasts future results as is required by scientific procedures for a model to be considered valid.
Even the IPCC in their Fourth Assessment (Section 8) point that out and call for more work to be done.

Knowing Al Gore's amazing ability to conjure who images of grandeur for himself....as in claiming to have invented the Internet surely poses credibility problems for the man. Just as he relies upon James Hansen who works at the Goddard Institute of Space Studies (GISS) run by NASA. Hansen has been caught out using erroneous and false data in his models and has spurned the use of space based technology in his studies. That alone is an odd situation for NASA funded scientific studies. Is it the Satellite based sensors produce data that is contrary to his theories?
His models fail to accurately future temperatures which alone are enough to invalidate them based upon accepted scientific standards. Has any of his studies been given a legitimate Peer Review? Any of them? Just one even?
I do believe you are falling into the description of Warming Advocates that Roger Pielke, Jr. wrote of in his book "Honest Broker".
