IT has come to light that some of the advice given to the Intergovernmental Panel on Climate Change has been defective.

Scientists have not maintained the standards we have a right to expect of them, and it has led to conclusions that have been accepted internationally that are defective.

Obviously, the panel will need to ask more questions and obtain more reliable information in future.

I know that many people who are involved have their own agendas. Sometimes it is to promote an industry and sometimes it is to ensure that activities which could well be harmful are continued unabated.

It is the responsibility of governments and for individuals to try to ensure that unpleasant consequences do not materialise from our activities and to modify our ways when we have the evidence that it will benefit future generations to do so.

I cannot avoid noticing the passion of those who want to make the case for making no changes because they probably derive benefits from how we conduct our lives and businesses at the present time.
