Confirmed: Southern hemisphere CO2 level rises above symbolic 400 ppm milestone, [Excellent pictures, graphs, diagrams] The Age May 15, 2016 –Peter Hannam Environment Editor, The Sydney Morning Herald
NASA | A Year in the Life of Earth’s CO2
A significant marker of rising global greenhouse gas emissions has been passed, with a key monitoring site on Tasmania’s north-west tip recording atmospheric carbon-dioxide exceeding 400 parts per million for the first time.
As foreshadowed by Fairfax Media last week, a baseline reading at the Cape Grim station that exceeded the 400-ppm mark of the primary gas driving global warming was imminent.
As it turned out, “the unfortunate milestone” was reached on Tuesday May 10 at 8am, local time, said Peter Krummel, who heads the CSIRO team analysing data from the most important site in the southern hemisphere.
Atmospheric readings from Cape Grim, along with two stations in Hawaii and Alaska, are closely watched as they date back decades and closely track a range of pollutants from ozone-depleting chemicals to the various greenhouse gases resulting from burning fossil fuels and clearing forests.
Mr Krummel said that while mostly symbolic, the 400-ppm reading “highlights the problem of rising emissions, which are increasing more rapidly than they used to be”.
A report out earlier this year from the World Meteorological Organization noted atmospheric readings of CO2 at the Mauna Loa site in Hawaii rose 3.05 ppm in 2015 alone – the biggest increase in the 56 years of research……
Climate scientists, such as David Karoly at Melbourne University, note that when other greenhouse gases, such as methane, are included, the situation is even bleaker.
The so-called carbon dioxide-equivalent level that takes in the full global warming impact is now about 485 ppm.
Both 2014 and 2015 were record hot years globally in data going back about 130 years. With the effect of a strong El Nino overlaying long-term trends, this year is likely to be even hotter after a scorching start.
Tasmania completely powered by renewable energy as rainfall boosts hydro dams ABC News 12 May 16, Tasmania is being completely powered by renewable energy for the first time this year, Hydro Tasmania says.
- Sustained rainfall fills dams by more than 3 per cent over 10 days
- All diesel generators and gas power stations have been turned off
- Rough weather hampers repairs to Basslink cable
The state has been in crisis for several months with dam levels at record lows after unprecedented dry weather…….
Hydro Tasmania CEO Stephen Davy said the state’s emergency diesel generators had been switched off through the week and the gas fired Tamar Valley Power Station was turned off yesterday.
“The past 10 days have been very positive,” he said.
“We’ve had more rain than predicted and our storages have risen strongly.
“There’s currently enough hydro and wind energy available to meet all Tasmanian demand.
“For the first time in months, our island is being powered solely by renewable energy.”…..http://www.abc.net.au/news/2016-05-12/tasmania-completely-powered-by-renewable-energy/7408148
Senate inquiry told of need for more research into bushfire-climate change links May 3, 2016 BLAIR RICHARDS State Political Reporter Mercury CALLS for more research into the links between climate change and bushfires and for greater national firefighting capacity have emerged from a Senate inquiry into the Tasmanian Wilderness fires.
The Senate’s environment and communications reference committee is examining the response to the fires that blazed through more than 20,000ha of the state’s Wilderness World Heritage Area in January and February.
The inquiry has received 24 submissions from stakeholders including scientific and conservation organisations, government agencies and individuals.
Some submissions called for more research into the impact of climate change on fire risk:…….
THE Australian Conservation Foundation said the fires should be a “wake-up call” for Australian governments to act on climate change.
However, the Tasmanian Government’s submission said the forecast outlook for the Tasmanian Wilderness World Heritage Area was classified as “normal”.
The Senate committee is due to report by May 30. http://www.themercury.com.au/news/politics/senate-inquiry-told-of-need-for-more-research-into-bushfireclimate-change-links/news-story/4ab57529e85c2a55a9ec82fbd64a2f0e
OCEAN temperatures on Tasmania’s East Coast are now among the most rapidly warming in the world, with oyster, salmon, rock lobster and abalone industries feeling the impact.
The Australian Renewable Energy Agency yesterday announced $2.9 million to help a project to help fund solar panels and batteries for up to 40 households on the island.
Harnessing the surplus power they generate is hoped to help take pressure off Bruny Island’s power system during peak times.
The systems will include software that allows homeowners to sell their power back to the grid during times of peak demand — and hence prices — on the National Electricity Market.
“The reason Bruny Island was chosen was because of the constraints they have from their undersea cables,” he said. “A battery with a solar panel can be converted into a remarkable power station. It’s fast and can both produce and consume power in an instant — it’s the type of power station the future needs.”
He said the benefit for households was they could sell their power into the market at a price of about $1 per kilowatt hour — compared to the much lower 5.5c per kilowatt hour feed-in tariffs available at present.
TasNetworks will begin consulting Bruny Island residents about the project over the coming months and seeking expressions of interest via public forums on the island this year.
here are environment ministers Groom and Hunt backing the arrest and punishment of Australians who make a modest stand for threatened species that they, the ministers, should be protecting.
In an age of the accelerating and irreversible destruction of our Earth’s biosphere, the untoward and often unseen influence of its exploiters is eroding Australia’s time-honoured rights to peaceful protest.
It was inevitable that somewhere, some time, some citizens would face the repressive Tasmanian laws. That stand has now been made among the stately ferns of Lapoinya and will move to the High Court of Australia where the consequences are enormous for every environmental, social, cultural and Indigenous issue in Australia’s future
Bob Brown’s arrest in Lapoinya under new anti-protestor laws, The Saturday Paper, BOB BROWN, 19 Mar 16 A follows their use to arrest conservationists in the Lapoinya forest. “…….The logging at Lapoinya torpedoed any hope Forestry Tasmania had of winning Forest Stewardship Council (FSC) certification, the internationally recognised green accreditation increasingly sought by global markets. FSC depends on respectful relationships with local communities………
Through all of this, the nation’s most powerful potential guardians of Australia’s forests and threatened species, Prime Minister Malcolm Turnbull and the federal minister for the environment, Greg Hunt, failed to lift a finger.
In Australia, the option of choice for setting back conservation is the strangling of environmental protest. As the resource-extraction industries come under fire for increasing encroachments on farmland and places of high natural or cultural heritage value, a key strategy is to have governments outlaw effective political protest……..

Bob Brown challenges Tasmania’s anti-protest laws in High Court ABC News 9 Mar 16 Former Australian Greens leader Bob Brown has issued a High Court challenge to the Tasmanian Government’s anti-protest laws.
The legislation which passed Parliament in 2014 allows for on-the-spot fines and tougher penatlities for repeat offenders.
Mr Brown and a number of others were arrested and charged in January, under the new laws, for protesting against the logging of Lapoinya Forest in Tasmania’s north west.
He issued the High Court challenge on the grounds the laws were contrary to the implied freedom of speech on government and political matters under the Australian constitution.
“I know that a challenge in the High Court can be a very expensive thing but I also know that a lot of people are worried about this legislation and the spread of it in other states,” he said.
“The laws will, if not challenged, trap everybody who wants to take a stand against something that’s manifestly wrong going on in our country.” Mr Brown said the Tasmanian Government promised the laws were not aimed at “mum and dad” protesters.
But he said “first up, they trapped a young mother and nurse who grew up in the Lapoinya area and a local grandfather”.
Hobart solicitor Roland Brown said the High Court challenge was a test case.
“This case is unusual because it’s seeking to have made invalid, or declared invalid, legislation that targets people’s political belief and their opinion in relation to environmental, social, cultural and economic factors,” he said………http://www.abc.net.au/news/2016-03-10/bob-brown-flags-high-court-challenge-to-workplace-protest-laws/7236124
King Island is emblematic of the challenges and opportunities facing the state. It is blessed with natural resources, but punished by its relative remoteness and lack of economies of scale. It has been a perfect testing ground for renewable technology, and has led to the Hydro exporting novel approaches to overseas markets. The project has already avoided the use of 18 million litres of diesel, and saved more than $24 million.
Tassie must look to future in renewables, February 29, 2016, ROSALIE WOODRUFF, Mercury “……… The Paris climate agreement sends a clear message to governments and investors that the age of fossil fuels is finished. There is a momentum around renewable energy generation, pushed by an urgency to respond to global warming and an explosion of new technology.
From crisis comes opportunity. The Greens are focused on the long-term task of transitioning Australia away from dependence on fossil fuels. The future is clearly in renewable energy generation, for pragmatism and prosperity.
We have released the Greens Energy Strategy, a blueprint for how the state can get started immediately on setting the business conditions we need to attract medium to large-scale renewable projects.
Our target is for Tasmania to be self-sufficient in clean electricity generation by 2022, and to be net exporters to the mainland. This is achievable. Continue reading
Acknowledging the attempt had little chance of success in the Liberal-dominated State Parliament, Greens leader Cassy O’Connor said the legislation needed to be overturned
Ms O’Connor said the legislation — which carries maximum fines of $10,000 and mandatory jail terms for repeat offenders — was being used against citizens protesting logging operations in the Lapoinya Forest — contrary to government promises about its intent.
“In recent weeks up at Lapoinya up in North West Tasmania, we’ve seen the Government’s draconian anti-protest legislation actually target the very people that Paul Harriss said it wouldn’t — mum and dad protesters.
“This Bill is not only highly political and draconian it is unnecessary — there is already legislation in Tasmania for trespass and public nuisance and we want to see this Bill banished from the statue books. “I believe this law will not remain on the statue books in Tasmania forever. It may be subject to a High Court challenge. It really has no place in a civil and democratic society like ours.”
Tasmanian spokesperson for Civil Liberties Australia. Rajan Venkataraman, said the Bill was a severe infringement on the right to peaceful protest. “The provisions in this Act are quite unique to Tasmania,” he said.
“Around most jurisdictions in Australia and indeed many countries around the world, they have provisions regarding trespass and public nuisance and certainly violent protest … but this kind of Act specifically targets protesters and specifically peaceful protesters. “The offences created by the Act and the penalties imposed are extreme and not in proportion to penalties imposed under other statutes, even for quite serious and violent offences.”
Resources Minister Paul Harriss dismissed opposition to the laws.
“It says a lot about the Greens that at a time when the state is a facing a number of serious challenges, they are most concerned about changing the law to allow their mates to try to stop others from lawfully harvesting a regrowth forest.”
Renewable energy a power coup for island http://www.theadvocate.com.au/story/3489296/renewable-energy-a-power-coup-for-island/ THE use of renewable energy to power King Island’s electricity supply for 33 successive hours has been hailed as a significant milestone. The latest achievement of the Hydro Tasmania’s King Island Renewable Integration project was an unprecedented milestone, project director Simon Gamble said.
“What makes this significant is that we’ve used renewable energy to support the needs of an entire community, which includes residential and industrial loads, for a full day,” Mr Gamble said.
“Our system has successfully managed the peaks in energy consumption that occur over the course of a full day, including early evening when demand is at its highest and there’s no solar contribution.
“It’s the first time anywhere that this has been achieved at a megawatt scale for such an extended period of time.”
King Island mayor Duncan McFie said the progression of the project helped to support the image of the island, and Tasmania, as clean and green.
“That King Island is leading the way on this is a highly significant achievement,” he said. Australian Renewable Energy Agency chief executive officer Ivor Frischknecht said the project was an example of how renewable energy and enabling technologies could work together to provide stable, reliable power.
“Hydro Tasmania is using a unique combination of technologies to reduce King Island’s reliance on expensive shipped-in diesel and provide residents with a more secure and reliable energy source,” he said. “This innovative energy solution could benefit off-grid communities on islands and in regional mainland Australia. “I look forward to seeing Hydro Tasmania continue to refine and commercialise its approach in other locations
India’s renewable energy technology inspires Tasmanian tomato business ABC Rural By Laurissa Smith, 17 July 15 A tomato farm in Tasmania’s north-west is turning to India’s latest technology in renewable energy to reduce its power bills and improve yields.
The Brandsema’s at Turners Beach plan to install a biomass gasifier to power its greenhouses. The gasification system, built in India, turns agricultural or forest waste into energy and as a by-product, creates CO2 for plants.
Grower Marcus Brandsema recently travelled to India. He met with manufacturers and engineers to watch the biomass plants in action.
“What happens is the organic material goes into a gasifier,” he said. “It’s operating at a reasonably high temperature, around 800 degrees Celsius or thereabouts, in a reduced oxygen atmosphere.
“The organic material doesn’t actually burn, but it oxidises and gives off a gas which is useful to use downstream.
Once the gas is produced we can then use it to fire a boiler to create hot water, which is what we need, especially in Tassie’, to grow tomatoesMarcus Brandsema, tomato grower
“They clean it and use it in an engine, which can drive a generator, or a pump, or alternatively the gas can be used as fuel source.”
Mr Brandsema is particularly attracted to the system’s ability to generate additional CO2 for the greenhouse to enhance photosynthesis.
“Once the gas is produced we can then use it to fire a boiler to create hot water, which is what we need, especially in Tassie’, to grow tomatoes,” he said.
“But the by-product of that is CO2, which would normally go up the flue as an emission, we could extract from the flue and introduce it into the greenhouse.”……..http://www.abc.net.au/news/2015-07-17/renewable-energy-gassification-plant-1707/6627444
State Energy Minister Matthew Groom hails wind farms in departure from PM HELEN KEMPTON MERCURY JULY 03, 2015 UNLIKE the Prime Minister, Tasmania’s Energy Minister Matthew Groom is a fan of wind farms and says more infrastructure needs to be built to capitalise on the state’s renewable energy headstart.
“I support the renewable energy broadly,” Mr Groom said after speaking at yesterday’s Tasmanian Minerals and Energy conference at Queenstown. “We have extraordinary resources in Tasmania and some of the best sites on the face of the planet on which to build them
Mr Groom said he was pleased the passing of Australia Renewable Energy Target legislation had given certainty to the wind industry and he looked forward to seeing progress on a new wind farm at Granville Harbour, near Zeehan.
Mr Groom said building a second interconnector cable across Bass Strait to export power was a key part of making the most of our renewable energy advantages. He said that cable needed to be viewed as a national infrastructure and, unlike Basslink 1, should be funded as such.“If a second cable is justified by a business case, it should be seen as a regulated asset funded through mainland users and perhaps a federal contribution,” Mr Groom said.
He said Japanese investors who recently visited Tasmania were gobsmacked by the state’s energy mix, and we needed to harness that competitive advantage………http://www.themercury.com.au/news/
Granville wind farm project awaits Senate vote http://www.perthnow.com.au/news/national/granville-wind-farm-project-awaits-senate-vote/story-fnjj6012-1227411859560, 23 June 15 HELEN KEMPTON Mercury THE 1900 cattle grazing on Tasmania’s most isolated farm will soon share the land with up to 33 wind turbines if Australia’s Renewable Energy Target is passed in the Senate tomorrow.
West Coast Wind plans to start construction of its wind farm on Royce Smith’s 1255ha beef property at Granville Harbour, outside Zeehan, at the end of the year. Already, a wind monitoring station is recording bankable energy data as investors in the $200 million project are secured. At 80m tall, the wind monitoring tower is as high as the turbines will be.
Tasmania looks to EVs as next step to 100% renewable energy, REneweconomy, By Giles Parkinson on 19 May 2015 Tasmania looks to fast-track take-up of electric vehicles to boost its credentials as a green manufacturing hub to replace old industries, and export clean energy to the mainland. Tasmania could end up totally renewable – a Green Apple Isle – in both electricity and transport. Tasmania is looking closely at electric vehicles to take the next step towards 100 per cent renewable energy – both electricity and transport – and boost the state’s strategic advantage as a clean energy manufacturing hub.

Renewable energy and potable water for Flinders Island community
ABC Rural By Rosemary Grant 22 Apr 15 The Bass Strait community of Flinders Island says two major projects to deliver clean water and electricity represent the future for remote settlements.
Over the 18 months, $25 million will be spent; half on a renewable energy scheme, and the rest on potable water for the main towns of Whitemark and Lady Barron.
Flinders Mayor Carol Cox said replacing old fossil fuel power stations with a new lower carbon energy source was a global aim.
Mrs Cox said it was the third time the council had tried to get a reliable renewable electricity system, and the funding commitment would make Flinders Island the benchmark for remote communities………
Mrs Cox said existing wind power would be integrated with a new wind energy generator, solar energy panels at the airport and a new solar energy field around the power station.
Hydro Tasmania will design and install the new $12.9 million multi-source renewable electricity system on Flinders Island.
Project manager Simon Gamble said it was an exciting prototype that would be the benchmark for remote communities in the Pacific and Asia. Continue reading
