"The planet has warmed and cooled several times over the past 150 years, all within the range of natural climate variability. There are no published scientific papers that show irrefutable proof that any of this is human-caused. Proof is not to be mistaken for the output of hypothetical climate models, none of which has been shown to reliably predict climate." Chris de Freitas, guest contributor to the New Zealand Centre for Political Research.
