DEAR SIR: The Intergovernmental Climate Change Panel recently issued another report claiming urgent action is needed to tackle global warming.

They rely on government funding and need the public to believe them in order to keep their jobs.

They are the official head of a vast green organisation that has infiltrated every level of government in the US and Europe.

They have brought their influence to bear on policy, but also on the appointment of staff to key positions and into schools. Anyone who questions their theory is being discriminated against and labelled a denier.

Opposition is being provided by scientists, engineers, environmentalists and lay people who are retired or able to make a living despite official isolation. The computer models on which they base their predictions are grounded on a set of assumptions based on opinion. When it was pointed out that there has been no global warming for the past 17 years, they changed the name to climate change.
