Site: Jo Nova

Slant: Sceptic

Active: yes


Who knew thousands of unpaid scientists are rising in protest against name-calling bullies and rent-seekers?

Jo Nova is one. She’s a prize-winning science grad and author, and her site gets over 2 million hits a year. A long time ago she was a Green, and still wants to save the world, but with the scientific method (…a perfectly good civilization is going to waste.)


Andrew Bolt described her writing as “outstanding”, and called one piece “a magnificant polemic.” She’s been quoted by James Delingpole, Christopher Booker, and Mark Steyn. She’s been blamed for the collapse of the ETS and named in the Australian Parliament. The Oxfam report on ClimateGate news improbably listed her blog influence as being equal to NASA in the Climategate email saga. The Wheeler Centre in Melbourne listed Jo Nova as the balancing counterpoint to the combined scientific weight of The UN and government departments. She must be doing something right.

Jo Nova: Transformation glitch? Biggest issue facing South Australia is electricity say 70%

A Sunday Mail survey (paywalled) shows that despite SA having more “free, cheap and clean” renewable electricity than just about anywhere in the world, the number one biggest issue for most South Australians is … “electricity”. And despite all the renewable jobs created, the second most common concern is “jobs”. Going for the Paradox-Trifecta: most strangely of all, with elected leaders who…

Jo Nova: Rising sea-levels in the Indian Ocean due to man-made “adjustments” not CO2

PMSML stands for Permanent Service for Mean Sea Level, though there is nothing permanent about sea-level data — like all obedient climate change data, its subject to change fifty years later – and the adjustments are as large as the trends.

We’ve seen this pattern in so many places. Now Cliff Ollier and Albert Parker have shown it in the Indian Ocean looking at Aden in Yemen, and Mumbai in…

Jo Nova: Giant Fans will cool Great Barrier Reef to stop bleaching

 ”Air-conditioning” of The Great Barrier Reef begins soon

To calm a few panicking people, the Australian Government will pay for large fans to circulate water on a minuscule portion of the 2,300 kilometer long Great Barrier Reef. The reef creatures, which have been coping with higher temperatures and bleaching for two hundred million years, will hopefully avoid the moving parts. Marine life…

Jo Nova: Another hidden cost of intermittent renewables (It’s time to talk about FCAS and roaring price spikes!)

The shape of normal AC Electricity: 50Hz (230V) and 60Hz (110V)

Nobody says much about FCAS in public  — but it’s become a hot topic among Australia’s energy-nerds and electricity traders. It never used to be a big deal, because we got it at very low cost from huge turbines — from coal, hydro, and gas. Suddenly, it is costing a lot more. As I discovered below, in one month FCAS charges in…

Jo Nova: Burn more oil and feed the world

Climate change causes … more crops.

Climate change threatens our food supply, our grain harvests. It causes wars, droughts, sometimes floods, shorter growing seasons. And we all know Climate change is here. We can see it out the window. Plus 2017 is one of the three hottest years ever.

Somehow all these bad events happened at once and added up to the world’s largest cereal crop ever.

It’s…

Jo Nova: Do 40,000 volcanoes matter?

The world is watching one volcano in Bali, but it’s sobering to think there may be hundreds of others going off, and almost certainly ones we don’t even know about. The article  Is the Bali volcano making us warmer or cooler? by William F Jasper, reminded me of Ian Plimers words about there being squillions of undersea volcanoes so I found the 2007 paper, by Hillier, that tried to count them.…

After lasting for thousands of years through wild swings of temperature, scientists could never have guessed that the Great Barrier Reef has evolved to cope with climate change.

The reef spans  2,300km and has spawning events so large that they can be viewed from space, but who knew that some parts of the reef appear to be safer and more resilient, and would repopulate the rest of the reef?…

A new study suggests temperatures across Antarctica have been falling for the last 1,600 years.  This natural climate change would have been a threat to baby penguins, forcing them to walk much further across sea-ice for food. (Looks like it was even worse for polar bears ). The cooling trend would have threatened inland lakes, shortened summer breeding periods, affected seal behaviour,…
