As spring exited into summer with record temperatures in much of New South Wales and South Australia, public support for strong action on the climate continues to grow. Margaret Gleeson reports. 

The Bureau of Meteorology says wind gusts up to 260km/h from a “supercell” thunderstorm and multiple tornadoes were recorded on September 28, destroying transmission towers and causing the state-wide blackout in South Australia.

The report from the BoM – which mapped the passage of storms and seven tornadoes over critical network infrastructure – makes it clear that a freak weather event was responsible for the grid blackout.

One Nation Senator Malcolm Roberts held a press conference on November 7 to release a 42-page document that claims the CSIRO and Bureau of Meteorology corrupted climate data and that global warming is an international Jewish banking conspiracy to gain global control through environmentalism.

A new climate is emerging in Australia, according to maps released by the Australian Export Grains Innovation Centre (AEGIC). AEGIC analysed data from more than 8000 Bureau of Meteorology stations around the country and discovered that traditional rainfall zones have shifted 100–400km since 2000. The only expansion of the winter rainfall zone has occurred in southeast Tasmania where winter rainfall has become more reliable.
