A Senior Advisor to Prime Minister, John Key has claimed that discussions over science of climate change are triggering a confidence loss in the science mechanisms.

The public has been struggling to determine what to believe and what not to, added PM's Science Advisor, Sir Peter Gluckman.

The apparent fallout of these debates is growing refutation and cynicism among the people over the scientists and the researchers. Also, people are gradually losing confidence in the Government claims.

The debate also undertook talks on growing effects of tobacco and cancer on the consumers and the spread of HIV-AIDs.

He pointed out there was no mention of heating up of glaciers or the emission of the greenhouse gases in the debate.

"Even in New Zealand, whose temperature is buffered by the surrounding ocean, native beech trees are already producing more seed at higher altitudes and welcome swallows are breeding noticeably earlier", he said.

Also, there were insecurities looming large over the possibility of melting of glaciers and discharge of frozen methane, which were nowhere to be heard in the debates, he said.

The debate is driven on interests of the economy and not the environment. The fossil fuel sector has been endorsing the debate, exclaimed Sir Peter.
