WHAT TONY JONES COULD HAVE ASKED: Yet Antarctic sea ice has hit record highs. Ocean pH measurements are even more uncertain that ones on ocean temperature. A “30%” range on a logarithmic scale is not as significant as it sounds, especially when ocean pH varies naturally by that much each day in some places, and many corals and fish seem quite capable of adapting. As far as drought and flood go, Australia has always had both, there were waves of 50-plus temperatures right across Australia in the 1800′s. Most climate scientists admit there is no concrete evidence at all that current floods and droughts or storms are on the increase, let alone that it’s caused by CO2?
