Right. If people cannot agree on how water vapor contributes to greenhouse effect then its a standoff of competing models. Since the left wants to attack capitalism anyway and exercise more government and global control over people’s lives they have too much invested in this to give up in five years. I believe this will go on indefinitely as a debate.
That ball's been snowballing downhill ever since.
The reason that carbon dioxide was chosen as the culprit instead of water vapor is that water vapor increases would be visible, in the form of increased cloud cover. Carbon dioxide possesses the convenient qualities of being colorless and odorless, thus it is much easier to pull off the con job.
