Ian Plimer (Geologist) has written a very interesting book on climate change. He has used science to back his reasoning (very deep reading but well worth the perseverance).
The IPCC (Intergovernmental panel for Climate Change) comprises some 2500 international scientists - some of who have majored in motor-cycle helmet design and fossil poo..!!!
Further-more, unbeknown to each other, both NASA and CSIRO conducted core sampling (NASA on sea-bed drilling & CSIRO on Antarctica ice core samples). Both authorities reached the same conclusion - Climate Change is cyclic.
