For Australia's sake, I hope Trump's climate science denialism loses

Anyone in Australia who witnessed the Black Summer bushfires (as I did), and anyone in the US who experienced the thick smoke from our western wildfires (as I have), knows how much damage climate change is already doing. The stark reality is that worldwide efforts to avert ever-more catastrophic climate change impacts lie in the balance in the 2020 US election.

Donald Trump will go down in history bearing substantial responsibility for the deaths of over 200,000 Americans due to his rejection of the advice of public health experts and his refusal to endorse policies such as social distancing and mask-wearing that could have saved many thousands of lives. But his rejection of the science of climate change sets the stage for a far greater toll. Far more human lives will be lost from the impacts of climate change if we fail to act.

Whether or not Trump gets reelected – andhow other countries like Australia respond to the outcome of the US election – could determine the fate of our planet. Indeed, I’ve stated that a second Trump term might well be “game over for the climate” if it leads to the collapse of international efforts to act.

The damage caused by Trump’s climate denial is painfully visible within the US as we endure climate changefuelled extreme weather events, including unprecedented wildfires in the west and unprecedented hurricanes in the east. But the damage can be felt around the world. Trump has proudly, and shamelessly, trumpeted his climate denialism on the global stage, joining with petrostates such as Russia, Saudi

Arabia and Brazil in opposing international climate efforts.

Indeed, Trump’s actions have emboldened Australia to be less ambitious on climate too, prime minister Scott Morrison following Trump’s lead in promoting climate denial, coddling fossil fuel interests and blocking efforts to support a clean, renewable energy transition.

By pulling the US out of the Paris agreement (one of the first and only campaign promises he kept) Trump ceded America’s leadership on the defining challenge of our time. Thus far, other countries have fortunately filled the leadership void, at least temporarily. The EU and China, with its new net-zero pledge, have stepped up to the plate, recognising that they will benefit from the opportunities of a clean energy economy and better protect their citizens from dangerous climate change impacts.

But nobody stands to benefit more from climate action, or lose more if we fail to act, than Australia. Having spent a sabbatical leave down under earlier this year, aimed at collaborating with scientists in Australia to study
