If ever there was going to be a climate change election, surely this (2016) was going to be it.
As May came and the election date was announced, the implications of the global Paris agreement between more than 190 countries just months earlier were still resonating – the world was moving away from fossil fuels and the challenge to keep global warming well below 2C was agreed.
The globe had just had its hottest year on record. April was the 12th consecutive month to break global heat records. In Australia, we just had the warmest autumn on record.
Levels of carbon dioxide in the atmosphere, taken at Cape Grim in Tasmania, passed a symbolic 400 parts per million, driven by the burning of fossil fuels. Moves to cut climate research at the CSIRO made international headlines.
And then, of course, there was the worst global coral bleaching event on record, bookmarked by the worst known bleaching event on the Great Barrier Reef, killing about a quarter of all corals mostly in the once “pristine” northern section.
This disaster coincided with the hottest sea surface temperatures on the reef in the Bureau of Meteorology’s records going back to 1900.
So climate change and clean energy should have been the red-hot issue.
But instead, at least between the ALP and the Coalition, the reaction to these seismic events was, mostly, meh.

Underwater Heat Wave Devastates Great Barrier Reef
Hardest-hit area includes some of Australia’s most remote and pristine coral
- March 29, 2016
CANBERRA, Australia — An underwater heat wave is devastating huge swaths of Australia’s Great Barrier Reef, marine researchers have found.

Great Barrier Reef bleaching may be last wake-up call, marine scientists say
Extensive bleaching has been caused by higher ocean temperatures
To prevent further damage, governments should commit to lowering emissions, an Australian team says
"This has been the saddest research trip of my life," James Cook University professor Terry Hughes, the convener of the National Coral Bleaching Taskforce, said in a press release after the team aerially surveyed almost 2,500 miles of the northern Australia reefs.
Coral bleaching is a modern phenomenon, marine scientists say; Over the past 400 years, there's no evidence of bleaching events until the late 20th century. Changing environmental factors like rising sea temperatures can cause the coral to expel their photosynthetic algae, called zooxanthellae, making many turn stark white. Others remain vivid, but have lost the green and brown hues that signal health. Without the symbiotic algae to process sunlight into oxygen and other nutrients, the coral dies.
"What we're seeing now is unequivocally to do with climate change," Prof Justin Martin University of Queensland told the ABC
