CHARLOTTE BULL’S letter regarding climate change (HAS, Jan 8), has a strangely contradictory tone.

At one point, she says “it would be unfair to suggest that all the 2,500 IPCC (Intergovernmental Panel on Climate Change) scientists working on the project were somehow corrupt”. How very magnanimous of her.

In the next sentence, she claims that “the global warming theory is rubbish because the research has been either deliberately lost, changed or manipulated to produce what is required”.

Perhaps she could explain what she means by the research being manipulated “to produce what is required”? Required by whom?

Who are these people doing the manipulation and to what purpose?
