被公开的一封邮件里面，Tom Wigley写给Jones 的有这样一封：
"I have always thought W-C W [wang] was a rather sloppy scientist. I therefore would not be surprised if he screwed up here … Why, why, why did you and W-C W not simply say this right at the start? Perhaps it's not too late? I realise that Keenan is just a troublemaker and out to waste time, so I apologize for continuing to waste your time on this, Phil. However, I *am* concerned because all this happened under my watch as director of CRU and, although this is unlikely, the buck eventually should stop with me."
可见问题之严重。
IPCC报告问题出得最严重的是WG2，这一组负责恐吓公众全球变暖的后果；因为没有足够的Peer reviewed研究结论，他们就东抄西抄，什么喜马拉雅冰川2035年消融，气象灾害，北非粮食减产一半，都是WG2搞出来的。
