The original Brexit

The first Brexit happened a very long time ago. According to Richard Webb in Brexit, 10,000 BC: The untold story of how Britain first left Europe (New Scientist), the white cliffs of Dover did not exist 450,000 years ago, just rolling hills. However, as usual, there was an ice age, and a glacial lake was formed in what is now the North Sea:

Federal election campaigning has started

As PM Scott Morrison reels from the latest crisis, and polls show that he’s in trouble, two big events signal the election race is up and running.

In brief, we had the ALP National Conference, which ScoMo attempted to disrupt by announcing the next Governor General. Then the Mid-Year Economic and Fiscal Outlook 2018‑19 showed the economy producing unexpected riches. However, the media were diverted by NP member and Assistant Finance Minister Andrew Broad’s ‘Sugar Daddy’ scandal, which, according to the Betoota Advocate, his leader Michael McCormack explained was a private family matter and hence none of our business. Meanwhile two opinion polls came out, which were not to ScoMo’s liking. Continue reading Federal election campaigning has started

1. How realistic is space travel?

As reported in the New Scientist, Frédéric Marin, an astronomer at the University of Strasbourg, France and Camille Beluffi, a physicist who works for Casc4de, a data firm in Strasbourg, have done a thought experiment on the feasibility of reaching the nearest Earth-like planet, which happens to be Proxima b, around 4.25 million light years away, a mere 40 trillion km.

Where will we be in 250 million years time?

A bit longer than 250 million years is when we had the Great Dying, the Permian–Triassic extinction event, when up to 96% of all marine species and 70% of terrestrial vertebrate species became extinct. A mere 65 million years ago saw the extinction of the dinosaurs and the dawn of the Cainozoic Era. From a screenshot of this YouTube, this is how the continents were placed around the globe:

1. Battery storage to grow four times quicker than market thinks

The latest Morgan Stanley report is bullish about the growth of battery storage in the Australian market. They think we’ll have 6.6GWh of battery storage in Australia by 2020, which is what the Australian Energy Market Operator last week predicted for 2035. Continue reading Climate clippings 176

1. Garbage out, garbage in

Stuart Robert had to go. Ben Eltham goes through the detail and finds his defence “is somewhere between threadbare and farcical.” So Malcolm told him to resign, and he did.

So with Mal Brough and Jamie Briggs in the naughty corner, plus Warren Truss and Andrew Robb giving the game away, we now have five vacancies. Continue reading Saturday salon 13/2

Goodbye Holocene, hello Anthropocene?

It hasn’t happened yet, not officially. The final decision rests with an august scientific body called the International Commission on Stratigraphy, which has a 36-person Working Group on the Anthropocene. Now 24 scientists, including some from the Working Group, have produced a paper advocating for the Anthropocene to be recognised as having begun in the mid-20th century. Continue reading Goodbye Holocene, hello Anthropocene?

Innovation and economic complexity

Goran Roos, Adjunct professor at University of Technology Sydney, explains why advanced manufacturing is an essential feature of ‘economic complexity’ and that “a nation’s potential to create prosperity is a direct function of its economic complexity.”

Australia’s economic complexity has declined over the last 25 years, to the point where it ranked 53 among all countries in 2012. The top three were Japan, Switzerland and Sweden. Losing the car industry is likely to lower Australia’s economic complexity by a further 5-15%. The share of manufacturing in Australia’s economy is likely to be below 5%, compared to Switzerland’s 20%. Continue reading Innovation and economic complexity
