I saw a pheasant coucal in the Broome garden where I stayed last week. Large bird that moved too quickly for a photo.

Surprise 😲
Ice cores show atmospheric CO2 increasing since the start of industrialisation.
So do Mauna Loa records since 1960s.
Facts, not disinformation.

Big state, big costs providing services over 2.5M sq kms.
Electricity and transport agency costs are high.
All State Govt's are having trouble meeting community expectations for health services to an aging population.

Levelised cost of energy shows renewables make sense financially - energy prices do not rise.
Here's some modeling (from sen.asn.au/renewables/)

Soooo exciting - a hot new source of info about tropical cyclones/hurricanes.
Showing climate change effects with storm tracks.
Hurricane Erin reached Cat 5 with unusually warm waters making a hurricane 90 times more likely.

Thanks for your interest.
I had a look but can't see the source of that snap shot, so I can't verify the data.
FYI: Swiss Re offers interesting graphs (based on verified data) that show the escalating trend in weather related losses:

#TheirABC ran an interview this morning with a WA shire mayor.
Grave concerns about a small town's (pop. ~750) pub that might get damaged by high tides next month.
Not once did anyone say "climate"change".
Awesome avoidance continues to plague Australia.

Both sides of the duopoly have starved and scrapped capacity out of our BoM.
Both parties appear intent on crippling global climate modelling by removing data from the great southern land.

Late Feb saw 6 cyclones in the southern oceans, including Cyclone Alfred.
Warmer ocean temps are driving increased numbers of cyclones.
