Koalas extinct? Hardly. “Nearly everything you have read or heard about koalas is wrong”

Since Europeans arrived Koalas have been booming and busting

The calls were out this week saying that koalas will be extinct in New South Wales in 30 years. But they didn’t mention that Koalas thrive and multiply so fast that in the right conditions scientists talk of ‘plagues’. On Kangaroo Island last year, there were so many koalas, the South Australian government has been trying to sterilize or relocate thousands of them over the last twenty years. Periodically scientists even discuss whether we have to cull them (the horror!).

They’ve survived twenty megafires in 200 years. They can recover. Ponder that Koalas were only introduced to Kangaroo Island in the 1930′s but by the 1990′s there were 14,000 of them and even though they are considered a tourism asset they are also considered a problem and pest too.

The Anthropocene: all that CO2 and the only mammal extinction is a brown rat on a desert island

Where’s the apocalypse: With all the forecasts of doom, is this it?

Global Lament is rising for the small brown rat (Melomys rubicola) lost off a desert island no one heard of til morning tea today. This is a rat that was only recognised as a distinct species in 1995, though even then, it was debated, and the rat’s existence was hanging by a thread. The island is a 5 hectare sand spit with a bit of low scrub and an old rusty scaffold once called a lighthouse. So it’s all of 0.05 square kilometers: it is so small there is no fresh water on the island, just the odd puddle after it rains. It’s all so ephemeral that over a decade or so the island shrank 40% and the vegetation was wiped out by 97% (details below). Life on shifting sands in the Torres Strait is all pathetically desperate. It’s 200km off Queensland but only 50km from Papua New Guinea and the highest point (if you could call it that) is 3m about the high tide mark. In other words, any decent wave could have washed the last one off. It’s sad, but it’s not “climate change”.

Climate change is real because we are snowflake couch potatoes, addicted to netflix and airconditioners

Welcome to the DroneAge, where people act like robots and share dumb ideas at light speed! Episode #601: Climate change makes you lonely and fat.

Feeling friendless, floppy and like a loser? It’s not your fault. Blame a coal plant. Blame Exxon. Blame anyone but yourself. It’s your bad luck to be born into the most bountiful, benevolent era in human history. Damn!

Lonely, unfit and hooked on air-conditioning – is this the summer of the future?

Nicole Hasham, Sydney Morning Herald, uses new unorthodox indicators of “climate change”. Wait for it… test cricket attendance? It’s a smorgasbord of nonsense:

In Perth, cricket fans avoided an historic Test fixture amid predictions of 38-degree days. Sun melted a coastal highway filled with holidaymakers in northern NSW. Victoria’s coal generators shut down. Tasmania burned. And rotting fish corpses lining the Darling River at Menindee forced anglers to seriously rethink their plans.

Are we kidding? Thirty-eight degrees is just a summer’s day in Perth. It’s something that happens 19 years out of 20. As for coal generators shutting down: we’ve spent 20 years trying to drive them out of business to stop climate change, and now, if they don’t work, that [...]

Solar cycles to blame for jellyfish plagues (not coal fired plants)

Image Erin Silversmith

Three amazing things in this story. One that solar cycles might influence the oceans to such an extent that jellyfish plagues are cycling in tune with the sun. Second is that the sun might control food for jellyfish on Earth somehow but have no effect on clouds, temperature or our climate (join the dots that expert climate models don’t). Third is that (briefly) there was actual scientific debate published on the ABC (even if only a few Australians were exposed to it). No one called anyone names, and both sides got to speak (albeit on different channels). Put it in your diary.

A couple of weeks ago on the ABC jellyfish were booming and it was because of climate change:

Jellyfish are causing mayhem as pollution, climate change see numbers boom

RN By Hong Jiang and Sasha Fegan for Late Night Live

…the brainless, spineless, eyeless, bloodless creatures are booming in numbers — and causing mayhem around the world.

Some scientists think jellyfish numbers are increasing as the climate changes — the creatures reproduce well in warmer waters.

Last year, Nick Kilvert of the ABC saw it as a [...]
