There is a lot at stake over not acting on climate change, or doing whatever can be done to ensure at least some of the Great Barrier Reef survives in a warming climate.

As Save the Children’s Paul Mitchell points out, that includes Australia’s responsibility to our neighbours:

The knock on impacts extend to our Pacific neighbours, such as Fiji, Vanuatu and the Solomon Islands.

The threats facing the Great Barrier Reef, such as increasing ocean acidification and temperatures, more intense storms and increasing coastal flooding, impact smaller reefs across the Pacific.

Liberal MP Dave Sharma was on the ABC’s Afternoon Briefing reminding us that there are Liberals who will push back against the Nationals increasingly loud rumblings on climate and net zero by 2050:

I don’t expect the prime minister will change his position on this. This is a position the cabinet has adopted and reflects the leadership of his party, the Liberal party.

It is not a position on the Nationals but in terms of the Liberal party, the prime minister has articulated our views and position on this. He is a leader of the government and the Nationals form part of that government. What he’s had to say on this remains government policy and will continue to remain government policy.
