Climate science has established that climate change and associated global warming will impact the world. Already the global temperature has risen by between 0.2 and 0.6 degrees centigrade since the late 19th century, and in Australia, average temperatures have increased by 0.8 degrees centigrade (Pillora 2010). Furthermore, the last IPCC report concluded for the first time not only that climate change was real but reported a 90% certainty that it was also human induced (IPCC 2007). Moreover, Australia is predicted by 2030 to experience the following: (i) a further 1ºC of warming; (ii) up to 20% more months of drought; (iii) up to 25% increase in days of very high or extreme fire danger; (iv) increases in storm surges and severe weather events; and (v) a rise in mean sea level, with the anticipated range of sea level rise to be between 18 to 76 cm by 2100 (Pillora 2010: 4; IPCC 2007).
