Just in case anyone still thinks that scientists were on the bandwagon for cynical reasons, and that denialism puts their job at risk:

http://en.wikipedia.org/wiki/Robert_Watson_%28scientist%29

Andrew Revkin writing for the New York Times described Watson as an "outspoken advocate of the idea that human actions - mainly burning coal and oil - are contributing to global warming and must be changed to avert environmental upheavals."[3]

In April 2002 the United States pressed for and won his replacement by Rajendra Pachauri as IPCC chair. According to New Scientist, "The oil industry seems to be behind the move." The industry campaign to oust Watson had begun days after George W. Bush's inauguration in January 2001, with a memo to the White House from Randy Randol of oil giant ExxonMobil asking "Can Watson be replaced now at the request of the US?"[4]

What are you struggling to say?

Somehow that doesn't surprise me if it were true, but it is from Wikipedia.
