When Elon Musk dramatically promised to build a grid-scale battery in South Australia, the media was enthralled. Share traders and a string of Australian fund managers smirked. They’d seen it all before, and were shorting him in the market.
In that very week he was in the market with plans to raise $US1.15 billion in equity and convertible notes. I understand also that Tesla has gone strangely quiet about SA since then. Continue reading Climate clippings 201
At time of writing, cyclone Debbie is looming to make landfall at Bowen, south of Townsville on the Queensland coast:

1. Ballarat and Bendigo targetted for blackouts to keep lights on in NSW
It didn’t happen, but the phone call was made during the early February heatwave:
Victorian Energy Minister Lily D’Ambrosio confirmed she was approached by the Australian Energy Market Operator (AEMO) with the suggestion that either Ballarat or Bendigo could potentially lose electricity for a period of time to assist NSW.
Victoria was not impressed and have demanded an explanation. Continue reading Climate clippings 199
1. 39,000 lightning strikes
We had 39,000 lightning strikes in one storm the other day. Apparently more than a million in the first six days of summer if you count cloud-to-cloud strikes.
Nothing too unusual about all that if you’ve lived in these parts for a while. Continue reading Saturday salon 10/12
In what is called ‘attribution science’ climate scientists are getting better at analysing how much climate change has influenced particular extreme weather events.
In short, it is no longer a question of weather there is an influence, rather how much.
It would be useful to know, for example, whether the kind of storm that hit South Australia is still a once in 50 years event. Continue reading Climate clippings 185
1. Stupidity over SA blackout
“Ignorant rubbish” is what Victorian Premier Daniel Andrews called Malcolm Turnbull’s initial comments on the SA electricity blackouts. “It’s the weather, stupid”, is more or less what Bill Shorten said, and he was right. The press has reported two ‘tornadoes’ in the north of SA which made pylons look like this:
The questions to be asked in this case are not about the reliance on renewables, rather on why fractures to the grid 200 km north of Adelaide took the whole state down. Continue reading Saturday salon 30/9
NOAA’s annual State of the Climate report has recently been released, showing the climate change is proceeding apace on all fronts. The 300 page report compiled by 450 scientists from 62 countries confirmed there was a “toppling of several symbolic mileposts” in heat, sea level rise and extreme weather in 2015. From The Guardian:
“The impacts of climate change are no longer subtle,” Michael Mann, a leading climatologist at Penn State, told the Guardian. “They are playing out before us, in real time. The 2015 numbers drive that home.”

No doubt there has been wild weather before at this time of year, normally a drier time in Queensland. I took this screen shot of the BOM page just as the system had dumped its lot on us:

1. March scorcher
March temperatures were the hottest March ever and second largest monthly anomaly. Here’s NASA via Open Mind:

The WMO Statement on the Status of the Climate in 2015 was released on 23 March. In short, the world continues to warm, the seas continue to rise, and the weather becomes hotter, wetter and drier, with continued extreme conditions.
The UN has a useful summary, or go to the new WMO site, or access the pdf document directly.
There were reports on ABC RN’s The World Today and at Climate Central, but the best I found with images that go beyond the report was on our ABC. I’ll pick out some of the elements that interested me. Continue reading WMO Statement on the Status of the Global Climate in 2015
A total of at least 1GW of large-scale solar could be added to existing Australian wind farms, boosting renewable energy development, generation, and and smoothing its delivery to the grid, according to a new report from the Australian Renewable Energy Agency investigation the benefits of solar and wind “co-location.”

Using a new model, researchers from the University of Queensland and Griffith University, predict the global average temperature could rise by 1.5°C as early as 2020. The model is based on forecasts of population and economic growth combined with rising per capita energy consumption. Continue reading Climate clippings 166
