As the ever closing climate change frontier looms upon Australian Shores, with signs already evident in most parts of the country, the question remains- when will our politicians act? After the failure and promises of Governments of the past, impending reforms that never come and budgets that get built and then pulled out under the feet of hopeful scientists and activists, many cling to catastrophic weather events and foreign influence to encourage change. Yet as the drought sets in over most of the country, not even political tours and tourism hopes are enough to bring the rain where we need it the most. Perhaps, those that pray for rain in hope, can be the ones that encourage Government as it is needed. (more…)

Companies are still lagging on modelling and disclosing impacts of climate change – more business, government and regulatory action is required.  (more…)

Antarctica lost 3 trillion tonnes of ice between 1992 and 2017, according to a new analysis of satellite observations. In vulnerable West Antarctica, the annual rate of ice loss has tripled during that period, reaching 159 billion tonnes a year. Overall, enough ice has been lost from Antarctica over the past quarter-century to raise global seas by 8 millimetres.  (more…)

“To ignore evil is to become an accomplice” (Martin Luther King)

If there is a single critical issue science has ever conveyed, it is that altering the composition of the Earth’s atmosphere can only bear fatal consequences for nature and humanity. It is estimated that, to date, some 150,000 to 400,000 people world-wide have perished each year due to the direct and indirect effects of global warming (https://newrepublic.com/article/121032/map-climate-change-kills-more-people-worldwide-terrorism; https://www.scientificamerican.com/article/global-warming-and-health/), including for example 1833 in New Orleans, possibly 5000 in Porto Rico, 6329 by typhoon Haiyan in the Philippine. The list goes on. While these events have been documented in detail, the silence in most of the mainstream media regarding the connection between global warming on the one hand and the rising spate of hurricanes, storms and fires on the other hand, is deafening.

Australia’s “father of PV,” UNSW Scientia Professor Martin Green, has been awarded the 2018 Global Energy Prize, beating out a shortlist that included Tesla’s Elon Musk, and becoming the first Australian to win the $820,000 gong. (more…)

The outsourcing of nearly half a billion dollars of taxpayer funds to an independent Foundation to protect the Great Barrier Reef is unusual by any measure. (more…)

“Two plus two is five – if the party says so” (George Orwell).

Should anyone record the history of the 20th and 21st centuries, they may report that, while temperatures and sea levels were rising, the human sense of reality has been clouded by electronic systems, including television, the internet and smartphones, by science fiction, virtual realities, public circuses, fake news, gratuitous hype and superlatives which overtook  common sense and the quest for protection of the earth and the survival of the species.

Australians need to save Kosciuszko from legislative action that will lead to the decline of one of Australia’s most beautiful areas, its mountain water catchments and unique alpine native animals and plants. (more…)

Climate change is “a current and existential national security risk”, according to an Australian Senate report released on Thursday 17 May. It says an existential risk is “one that threatens the premature extinction of Earth-originating intelligent life or the permanent and drastic destruction of its potential for desirable future development”. These are strong words. (more…)

Peter Dawson reviews Sunburnt Country’ – Dr Joelle Gergis’ new book on Climate Change

Climate Scientist, Dr.Joelle Gergis’s book pulls together from wide-ranging sources the story of the Australian climate since white settlement, but also reaches back 1000 years and more. She seeks to convince us that the climate change challenge we face is, by every measure, real, menacing and urgent. It is both a comprehensive and a compelling answer to the climate sceptics.

Australia is a continent defined by extremes, and recent decades have seen some extraordinary climate events. But droughts, floods, heatwaves, and fires have battered Australia for millennia. Are recent extreme events really worse than those in the past?

In a recent paper, we reconstructed 800 years of seasonal rainfall patterns across the Australian continent. Our new records show that parts of Northern Australia are wetter than ever before, and that major droughts of the late 20th and early 21st centuries in southern Australia are likely without precedent over the past 400 years.

The extraction and transfer from the earth crust to the atmosphere of every economically available molecule of carbon, including coal, oil, tar sand oil, shale oil, methane gas, coal seam gas and other forms of hydrocarbon, constitutes the most significant shift in composition of the atmosphere since the PETM hyperthermal event about 56 million years ago and the K-T extinction of the dinosaurs some 66 million years ago.

What is widely regarded as the last budget to be delivered by the Turnbull government before the next federal election ceded no ground on climate policy, insisting that it’s much criticised emissions reduction targets would remain unchanged. (more…)

There must be a federal election coming as the government has announced a rescue package for the Great Barrier Reef. Like a damsel (fish) in distress, the Reef has experienced many rescue packages. As early as the mid-1990’s, the federal government introduced the Sugar Coast Environment Rescue Package which aimed to preserve important lowland habitats along the Reef coastline. Governments have been announcing rescue packages ever since. (more…)

Growing up near Midland on the outskirts of Perth during the 1960s and 1970s, I endured the weekly stench from the local abattoir. It was the price we paid to get meat to population centres. My first job was in the local meat processing plant, working with people described as “salt of the earth, working class”, who had historically toiled in appalling conditions because they had no choice.

Pressured by unions over postwar decades, Australian governments eventually stepped in to enforce decent standards for work and wages. Compelled by those who saw the immense cruelty involved, animal welfare laws were also imposed. Meat industry employers objected to red tape and higher labour costs, but community standards were enforced, most operators complied, and the worst operators eventually left the business. (more…)

“Fiduciary: a person to whom power is entrusted for the benefit of another”

“Power is reposed in members of Parliament by the public for exercise in the interests of the public and not primarily for the interests of members or the parties to which they belong. The cry ‘whatever it takes’ is not consistent with the performance of fiduciary duty”  Sir Gerard Brennan AC, KBE, QC

After three decades of global inaction, none more so than in Australia, human-induced climate change is now an existential risk to humanity. That is, a risk posing large negative consequences which will be irreversible, resulting inter alia in major reductions in global and national population, species extinction, disruption of economies and social chaos, unless carbon emissions are reduced on an emergency basis. The risk is immediate in that it is being locked in today by our insistence on expanding the use of fossil fuels when the carbon budget to stay below sensible temperature increase limits is already exhausted.

An article by Kerry Brewster in the Guardian this week reports on a significant fraud investigation by Queensland’s Major and Organised Crime Squad (Rural) into subsidies granted to a landholder under the Healthy Headwaters Water Use Efficiency Program. (more…)

The finer policy details of the of the proposed National Energy Guarantee (NEG) have begun to leak onto newspaper front pages and websites, ahead of Friday’s crucial meeting of federal and state energy ministers.

The good news is that the leaked information suggests solid progress has been made over the past couple of months on both the emissions and reliability components of the policy. (more…)

Australia was once a global leader in marine protection. Today, we have fallen spectacularly from grace. The Commonwealth marine park plans tabled recently in federal Parliament represent a triumph for the oil, gas and fishing industries and a massive backward step for our threatened oceans. (more…)

The NSW National Parks and Wildlife Service (NPWS) is facing a future crisis that perhaps is not fully recognised by supporters of nature conservation. Visitation is skyrocketing http://www.environment.nsw.gov.au/research/NSWparkspopularity.htm which on the face of it is wonderful. More and more people are beginning, potentially at least, to value our national parks and enjoy the experience of visiting them. On the other hand, successive governments have cut funding to NPWS.  Staff numbers and financial resources have dwindled relative to the areas to be managed. The solution on both sides of government seems to be to increase tourism opportunities with the help of commercial interests. https://publish.pearlsandirritations.com/john-menadue-the-new-squatters-in-our-national-parks/  That may be a reasonable response, but it shouldn’t come without some serious caveats. Do we really want the Starbucks solution as in USA National Parks? https://www.theguardian.com/environment/2018/mar/26/yosemites-secretive-starbucks-cafe-opens-in-park-to-delight-and-dismay    (more…)

In 2014 the NSW government hosted the IUCN World Parks Congress. The government touted securing the conference as a victory for their major events calendar. The key outcome of the congress was the Promise of Sydney – the Vision was excellent. The commitments, however, from the NSW Government were almost laughable, given the importance of the Congress on the world stage. http://www.worldparkscongress.org/about/promise_of_sydney_commitments.html The shallowness of the commitments said a lot about what had become of NSW National Parks and Wildlife Service (NPWS) which, through the 1990’s, had been described by the IUCN as one of the five best conservation agencies in the world.  (more…)

Solar photovoltaic and wind power are rapidly getting cheaper and more abundant – so much so that they are on track to entirely supplant fossil fuels worldwide within two decades, with the time frame depending mostly on politics. The protestation from some politicians that we need to build new coal stations sounds rather quaint.

The reality is that the rising tide of solar photovoltaics (PV) and wind energy offers our only realistic chance of avoiding dangerous climate change. (more…)

Daniel Ellsberg, former presidential advisor, who had released the famous top-secret Pentagon Papers related to the Viet Nam war, also possessed a cache of top secret documents related to America’s nuclear program in the 1960s. In this new  book “The Doomsday Machine: Confessions of a Nuclear War Planner” (5/12/2017) he reveals the contents of those documents, with their shocking relevance for today. It is an insider’s account of the most dangerous arms buildup in the history of the world, whose legacy threatens the very survival of humanity. Ellsberg’s analysis of recent research on nuclear winter shows that even a small nuclear exchange could expand to cause billions of deaths by global nuclear famine. (more…)
