• Jennifer Marohasy " Not Enough CO2 in Fossil Fuels to Make Oceans Acidic: A Note from Professor Plimer: The atmosphere once had at least 25 times the current CO2 content, we are living at a time when CO2 is the lowest it has been for billions of years, we continue to remove CO2 via carbonate sedimentation from the oceans and the oceans continue to be buffered by water-rock reactions (as shown by Walker et al. 1981).

• The effect of geographic range on extinction risk during background and mass extinction: Using logistic regression, we evaluated the selectivity of genus survivorship with respect to geographic range by using a global database of fossil benthic marine invertebrates spanning the Cambrian through the Neogene periods, an interval of ?500 My. Our results show that wide geographic range has been significantly and positively associated with survivorship for the great majority of Phanerozoic time.
