1. Climate change & extreme weather

2. “There is a scientific consensus over the reality of anthropogenic global warming.[It is based on]multiple, independent lines of evidence converging on a single coherent account.” Naomi Oreskes

3. CSIRO Climate Change in Australia 2007 “Australian average temperatures have increased 0.9°C since 1950, with significant regional variations.”
