NSW Liberals call for national debates on climate change science, by Sean Nicholls.

The NSW Liberals have formally called on the Turnbull government to conduct public debates about climate change – including whether the science is settled….

A motion passed at the party’s state council calls on the government to “arrange and hold public debates/discussions” between scientists from the Intergovernmental Panel on Climate Change and “independent climate scientists”.

About time. As it happens, the whole scare over increasing carbon dioxide is due to a simple modeling error dating back over a century to when the greenhouse effect was not even understood. The error was carried forward into all subsequent climate models. The error was recently found and publicized on a major climate blog, and I am writing a book about it at the moment.

Good news! Fixing this error and applying modern data shows that less than 20% of the global warming since 1973 was due to increasing carbon dioxide. Official estimates overestimate the sensitivity to increasing carbon dioxide by a factor of five to ten.

Also, it turns out that the bulk of the recent global warming was due to the Sun. A newly-discovered relationship predicts that there will be global cooling starting in about 2017 to 2022, and that the 2020s will be cooler than the 1980s.
