Chris Mitchell writes in 'The Australian': " Environment writers should accurately report what climate scientists say. But they should also report what economists and scientists in disciplines such as physics, astronomy and geology say. Climate science is a relatively new field and many in it know their computer modelling is far from perfect. The sun and the Earth’s core are the main sources of heat on our planet, so media sneering at reporting of the work of astronomers and geologists on climate is infantile."
