If anyone wants to completely and thoroughly debunk AGW or climate change all that needs to be done is to recap the so called settled science presented in the Inconvenient Truth movie. All of the models and predictions that were made based on settled science have not only failed to materialize, in fact the opposite has happened. Never snowing again in Britain as a example.
This can only happen if the data was bad to begin with, fabricated, or was just a scam to start with, or a combination of all three.
Al Gore single handed with his movie, destroyed the scientific credibility of climate change.
