Kevin Rudd’s latest effort for relevance is a mystifying act of historical revisionism. Writing to Jacobin, the former prime minister has attempted to defend his record on climate change, blaming the Greens for his climate failure.

I have a simple message for Mr Rudd: declaring climate change the “greatest moral challenge of all time” and yet failing to act is as great a sin as denial.

The Greens reached out to Rudd’s Labor Party to improve legislation and remove booby traps that would give giant polluters the chance to get off scot-free. But, as has been extensively reported, Labor decided they didn’t want to work with us because negotiating with, then driving a wedge into, the Liberal Party was a bigger priority for them. So we voted against legislation that would have locked Australia in to dangerous levels of global heating.
