1. Quiggin reckons Tesla battery can solve climate change
Assuming the Tesla system comes anywhere near meeting its announced specifications, and noting that electric cars are also on the market from Tesla and others, we now have just about everything we need for a technological fix for climate change, based on a combination of renewable energy and energy efficiency, at a cost that’s a small fraction of global income (and hence a small fraction of national income for any country).
We don’t need radical economic changes which will entail the end of industrial society/capitalism as we know it or nuclear energy on a massive scale.

We looked at the Tesla battery as such last week (see item 3).
- The University of Western Australia has cancelled the $4 million contract for a think tank spearheaded by controversial Danish academic Bjorn Lomborg.
The Australian Consensus Centre was going to be set up with the help of a $4 million Federal Government grant, but University Vice-Chancellor Paul Johnson last night said the proposed centre was untenable and lacked academic support.
The Education Minister Christopher Pyne has told newspaper journalists he’s seeking legal advice about the University’s decision to hand back the funding, but he says he’ll find another University to host the Consensus Centre.
Pyne and human rights commissioner, Tim Wilson, have objected to the university’s action on the grounds of free speech and censorship. Universities are about quality, not any old rubbish! Graham Readfearn looks at Lomborg’s economics and climate science, and finds both problematic, to say the least.
Maurice Newman is a former chairman of the Australian Stock Exchange, Deutsche Bank, the Australian Broadcasting Corporation and a former chancellor of Macquarie University.
Since September 2013 he’s also been the chairman of the Prime Minister’s Business Advisory Council.
- The Prime Minister’s top business adviser says the United Nations is trying to use the fear of climate change to orchestrate an anti-freedom, anti-capitalist new world order.
In an article in The Oz he urges Tony Abbott not to listen to the UN and resist attempts to get Australia to sign a climate treaty. But:
- The Australian Chamber of Commerce and Industry has distanced itself from Mr Newman’s comments and so has the Federal Environment Minister Greg Hunt.
Sensible. I’m with David Karoly. Maurice Newman lives in an alternative reality.
4. “It’s crazy to think that 2 degrees Celsius is safe limit”
David Spratt tells us that James Hansen told ABC Radio National Breakfast that “its crazy to think that 2 degrees Celsius is safe limit.” For example:
- We know that the prior interglacial period about 120,000 years ago – it’s called the Eemian – was less than 2 degrees C warmer than pre-industrial conditions and sea level was a least 6 to 8 metres higher…
- The ice sheets are losing mass faster and faster with a doubling the of [ice loss] about 10 years. If that continues, we would get sea-level rises of several metres within 40 to 50 years.
Back in 2011 Hansen said that the notion that 1.5°C is a safe target is out the window, and even 1 degree looks like an unacceptably high risk.
What is lacking in the politics of climate change is the notion of a safe climate. The IPCC processes are normalising 3°C as the best we can do.

During the northern summer of 2014 NOAA’s Mauna Loa observatory in Hawaii averaged above 400 ppm for several months in a row. Now, for the first time, the global average has topped 400 ppm for a whole month in March. Here’s the global graph:
For March the figure was 400.83 ppm, on May 4 it reached 403.90 ppm.
6. California drought could change food market
The Sierra Nevada Mountains supply a third of the state’s water. Last season the snowpack was 8% of the yearly average.
Governor Jerry Brown has mandated that urban water agencies reduce usage by 25%, but he has allowed agriculture, which uses 80% of the water, to carry on regardless.
Problem is the water is being used unsustainably. Groundwater resources in some areas are over-extracted by 80 per cent, with aquifers falling by 60 feet each year.
The scale is enormous:
- Californian irrigators used 28,986 gigalitres a year, compared to about 11,060 gigalitres in Australia.
This was used to produce up to $31 billion worth of irrigation produce each year, compared to Australia’s $13 billion.
A continued drought in California could disrupt the American food system and have ripple effects elsewhere.
