Constant refrain from alarmists: there *was* a climate debate, but now it's over

1. In 1992, Al Gore said:

Only an insignificant fraction of scientists deny the global warming crisis. The time for debate is over. The science is settled.

2. In April 2007, with Sheryl Crow sitting next to her, Laurie David said:

...the world has complete consensus on this....the debate is over.

(By the way, Laurie David was the real-life wife of Larry David, who was the inspiration for the "George Costanza" character in Seinfeld.)

3. In December 2007, Sheryl Crow explains that about "six months ago", people were still debating, but now "there's no more debate".
