We should urgently change how we generate electricity in Australia, but the government's claim to be on track to meeting its 2030 target is based on coal and gas generation permanently dropping to a third of current levels this decade.
They do not have the policies in place to make this happen.

Have a talk about climate change to a local high school today. Ironically the talk had to be moved from one hall to another due to the heat wave in Brisbane today. I consider this my climate activism to give talks to young people.

It would help if the Albanese govt stopped approving massive new polluting gas and coal projects
Australia warned it’s in danger of missing its 2035 climate targets without deeper pollution cuts.
Australia Risks 2035 Climate Goal Without Bigger Emissions Cuts
Australia warned it’s in danger of missing its 2035 climate targets without deeper pollution cuts, which in turn threatens the nation’s ambitions to reach net zero by mid-century.

Another thing: if we've only managed to cut real emissions by 4% since 2005, how do you think we're getting the rest of the way to 62-70% by 2035 with the same weak policies?
The land-use accounting tricks that got us to -28% aren't yielding any more.

Just to cut through the backslapping: the very small emissions reduction (2%) is nowhere near enough even for our own local targets. These are also the easiest cuts (ie from local pwr generation bc we are buying solar panels) and are only in one sector.
Exported emissions are 4x bigger and growing.

No surprise… we have a lot of work to do to scale up renewable energy and reduce our reliance on coal. But we can do it if there is political will… plenty of opportunities to increase solar, wind, pumped hydro etc… we currently have a surplus of solar so we need more batteries. #Aus

All latitude bands were warmer than average over the last 6 months. This was particularly visible across the Arctic and Antarctic regions. 🔥
Plot shows zonal-mean temperature anomalies, where latitude = y-axis (not scaled by distance). GISTEMPv4 data using their 1951-1980 baseline.

This seems ridiculous when they're about to completely overhaul the entire grants system – they've never undertaken anything so large before!
