Cape Grim in Tasmania is a measuring station for atmospheric CO2 in the world. The measurement there tends to be a bit lower than at Mauna Loa and doesn’t wobble about as much. It’s baseline stands at 399.9 parts per million and is about to break through the 400 mark, as shown in this graph:
The following graph shows the Cape Grim data show against the Alaskan Alert Observatory site and Hawaii’s Mauna Loa:
The 400 mark as such is mainly psychological, but the real story is that it is going steadily up as are the emissions in our country. A year ago Cape Grim’s CO2 readings were about 396.7 ppm, implying a jump of more than 3ppm since then.
This graph puts it in the context of the last 2000 years:
- emissions from the country’s main electricity grid covering the eastern states have risen 5.7 per cent – or 8.7 million tonnes – in the year to April compared with the final 12 months of the carbon tax that the Abbott government scrapped in July 2014, according to energy consultants Pitt & Sherry.
The share of coal in the National Electricity Market has risen to 76.2 per cent – its highest level since September 2012 – from 72.3 per cent during the period since June 2014, the consultants’ latest Cedex report said.
Cape Grim is run jointly by CSIRO and the Bureau of Meteorology. While CSIRO has not confirmed the number of researchers it will cut from the 30 or so involved in analysing CO2 levels in ice and the atmosphere, Fairfax Media understands about one-third will go.
- “CSIRO is again producing world-leading climate science, and it’s reprehensible that the Turnbull Government is allowing the slashing of CSIRO’s capacity to ring the alarm bells the world needs to hear,” Greens Senator Waters said.Fairfax Media sought comment from CSIRO on the size of the job cuts.
In justifying the cuts to climate modelling and monitoring programs, CSIRO chief executive Larry Marshall said that as climate change had been proved, resources could be diverted to climate mitigations and adaptation.
Meanwhile Greg Hunt continues to blather on about meeting and beating our targets.

The SMH article points out that 400 ppm is 0.04 per cent of the atmosphere, which may seem small but a similar level of alcohol would be close to the legal driving limit in Australia.
Meanwhile in New Zealand a decision has bee made to keep Huntly coal thermal power station open for another four years, sending their emissions targets up in a puff of smoke.
