Badly worded poll published by the SMH, which implies that it’s more costly overall/less affordable to reach net zero. Verging on a push poll.
Despite this, a majority of Australians still support net zero.

A new edition of the UNEP's Emissions Gap Report is out. It shows countries making little progress in ramping up ambition, and the very low likelihood of current commitments limiting warming to 1.5 degrees.
We're probably avoiding 3 degrees, but there's much more to do. www.unep.org/resources/em...

This 'free solar hours' announcement is smart politics, associating free electricity with renewables.
It's also reflects the real market, with wholesale electricity prices dropping below zero every day this week in NSW and QLD during the solar peak.

A member of the Senior Executive Services (SES, i.e. a senior public servant) within the climate and environment department accepted a gift ticket from Woodside to attend an industry conference.
Question is why even accept this when tickets were just $150.
Conflicts of interest come pretty cheap.

"Even achieving emissions reduction targets consistent with the ambitious goal of 1.5°C of global warming under the Paris Agreement will result in the further loss of 70–90% of reef-building corals compared to today, with 99 corals being lost under warming of 2°C or more"

The 'statement of reasons' given by enviro minister Murray Watt approving the North West Shelf gas project extension contains some astonishing mental gymnastics.
He assumes the same level of emissions could occur even if the project didn't proceed

Just a reminder that the federal court recently found the Australian government has a track record of failing to set emissions reduction targets consistent with the best available science.

So the report (which Bowen didn’t write) is ‘out of the playbook’ of… conservative political leaders? Like John Howard and Scott Morrison?

"Species will be forced to move, adapt to the new conditions or die out, with (on average) half of terrestrial species being exposed to climatic conditions that they do not currently experience, leading to potential species loss."

The assessment shows how unconscionable it is that some try to frame climate action as the domain of 'privileged city elites' when it is remote and regional populations who are the most at risk from future climate change.

One of the bleakest charts in the report:
"At +3.0°C of global warming, heat-related mortality is projected to increase by 444% in Sydney, 259% in Melbourne, 335% in Townsville, 312% in Perth, 146% in Launceston and 423% in Darwin compared to current conditions"
