1. Antarctic ice melt may have tipped
David Spratt at Climate Code Red has a post surveying recent studies on Antarctic ice sheet melting. I’ll cut to the chase with his update of a recent report from NOAA:
a revised worst-case sea-level rise scenario of 2.5 metres by 2100, 5.5 metres by 2150 and 9.7 metres by 2200. It says sea level science has “advanced significantly over the last few years, especially (for) land-based ice sheets in Greenland and Antarctica under global warming”, and hence the “correspondingly larger range of possible 21st century rise in sea level than previously thought”.

Renewable energy news
I’m reminded of my school days when our German teacher on the last day of term used to read us tales of Baron Münchhausen, who on one occasion jumped on his horse and rode off madly in all directions. There is so much going on, fully covered at RenewEconomy, so it is difficult to select the most significant. I’ll try a couple of themes, and include some AFR coverage, which is trying to keep business informed.
The South Australian tender for 100MW grid-scale storage has received 90 expressions of interest from 10 countries, demonstrating an established global industry. Continue reading Climate clippings 203
1. State of the Environment 2016
The government has produced the latest State of the Environment Report 2016 which happens every five years. I’ve browsed the report and can say that it has some magnificent photographs.
According to the ABS Australia’s population will be between 36.8 million and 48.3 million in 2066 as against 24 million now. The report says that the key drivers of environmental change are population growth and economic activity.
The report says that it is possible to decouple these drivers from environmental harm, but it’s a possibility only. Sue Arnold, following Ted Trainer and Sustainable Australia suggests that we have already breached our carrying capacity. Continue reading Climate clippings 202
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
The Murdoch media continues to lay the blame on renewables, a notion specifically rejected by AEMO, leading to a Twitter battle between SA minister Tom Koutsantonis and The Australian’s Adelaide bureau chief, Michael Owen.

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
The innovative LiquidPiston engine, mentioned by BilB, is targetting a global market worth $460 billion. It has a power to weight ratio more than ten times better than a regular engine:
The big bruiser on the left puts out 35 HP, the one on the right 40 HP. Continue reading Climate clippings 198
1. Global plan to save 10 per cent of coral reefs
A world-wide plane is being hatched a global plan says only 10 pc of coral reefs to save 10 per cent of coral reefs. The stark fact is that:
Scientists estimate 90 per cent of the world’s coral reefs will disappear in the next 35 years due to coral bleaching induced by global warming, pollution and over-development.
The 50 Reefs initiative, recently launched at the World Ocean Summit in Bali, in a donor funded initiative to identify the 10% of reefs most likely to survive past 2050. Effectively it’s a triage operation. Continue reading Climate clippings 197

This impressive bloom of blue blubber jellyfish showed up a few weeks ago beached at Deception Bay, just north of Brisbane:

Every year 20 million people move from the country to the city in China. Within that group is an urban wealthy class, some 5% of the population, and growing, who are responsible for 19% of household emissions. They want to live in big houses, drive 4x4s and adopt a Western life-style.
The very rich generate 6.4 tons of CO2 per capita per year − nearly four times the national average of 1.7 tons. Costa Rica and Thailand are mentioned as countries at a similar level of development, with only one tonne per capita. Continue reading Climate clippings 195
1. Methane emissions spiking
The Global Methane Budget 2016 has been released, and the news is not good.
CSIRO researcher Dr Pep Canadell said it was the most comprehensive modelling to date and revealed a potentially dangerous climate wildcard.
“Methane emissions were stable for quite a few years at the end of the 2000s. But they’ve begun to grow much faster, in fact 10 times faster, since 2007,” said Dr Canadell, who is also the executive director of the Global Carbon Project.

An AFR article about investors piling into lithium and graphite mining stocks tells a tale. With our focus on Tesla we are missing the story of China.
