Farm Lobbies Abandon Farmers: Media Release from Viv Forbes

June 30, 2008 By jennifer

“The Carbon Sense Coalition today accused the big farming lobby groups, government departments, politicians and Ministers representing agriculture of ignoring science and abandoning farmers to unjustified carbon taxation.

The chairman of “Carbon Sense”, Mr Viv Forbes, claimed that there was no justification whatsoever for including emissions from farm animals in any carbon emissions tax scheme.

“Every intelligent farmer can understand the carbon food cycle whereby every bit of carbon dioxide released by farm animals or plants into the atmosphere has previously been removed from the same atmosphere.”

“This simple process is surely not beyond the understanding of all the lobbyists, bureaucrats, researchers and media living off farmers?”

“In the farm sector carbon balance, apart from any fossil fuel used, it is a zero sum game, and all farm animals have zero net carbon emissions.”

“Grazing animals have not yet learned to live on coal or diesel fuel, and they cannot create carbon out of rocks, soil or water. Therefore they must extract it, via grasses and grains, from that marvellous gas of life in our atmosphere, carbon dioxide. All foods and organic matter represent carbon that has been sequestered by life processes into living matter. The carbon is simply recycled at zero cost.”

“Farm plants and animals are every bit as green as forests. Both farms and forests extract carbon from the air and store it in organic life forms until that organic matter is burnt or decays in the open air, thus returning their borrowed carbon to the atmospheric storehouse.”

“Why then do those who grow forests attract a carbon credit and but those who grow cattle and sheep cop a carbon tax?”

“Australia and New Zealand lead the world in harvesting solar energy and carbon dioxide to produce an abundance of clean green food. Why then are both the New Zealand and the Australian governments proposing to force farm animals into their emissions trading quagmire? And why are they subsidising the conversion of farmland producing food into forests producing nothing but carbon credits or crops producing ethanol motor fuel? What are future generations going to eat?”

Forbes claimed that farmers need to start agitating now or they risk being the only bunnies still paying carbon taxes.

“Motorists who vote and use petrol will escape the carbon tax by sleight of hand – petrol excise will in future be called “carbon tax”. Exporters will get an exemption to enable them to compete with more sensible regimes with no carbon taxes. Other protected species like working families in marginal electorates will get subsidies to cover carbon taxes on electricity bills. Truckies will blockade the roads if politicians add carbon tax to diesel prices. That leaves farmers as the only big group with so few votes and such incompetent leadership that they will pay the carbon tax.”

“Farmers have been abandoned by Ag Force, the Meat and Livestock Authority, CSIRO, the National Party, our “working families” Government and most of the similar organisations in New Zealand. It is not clear whether this is because of a lack of scientific logic or cowardice in the face of electoral hysteria on global warming.”

“But the politicians representing the treasured “working families” in the battling suburbs had better start taking notice of rising food prices or a more soundly based hysteria about the growing shortage of food will sweep emissions trading nonsense from the political landscape.”

Normalised Australian Insured Losses from Meteorological Hazards: 1967–2006

June 28, 2008 By Paul

Ryan Crompton and John McAneney of Macquarie University in Sydney, Australia have an important new paper in the August, 2008 issue of the journal Environmental Science & Policy titled “Normalised Australian insured losses from meteorological hazards: 1967–2006.” (Available to subscribers here). The paper contributes to a growing literature that documents the importance of understanding the integrated effects of societal change and climate change. The paper also underscores the central role that adaptation policies must play in climate policy.

The abstract states:

Since 1967, the Insurance Council of Australia has maintained a database of significant insured losses. Apart from five geological events, all others (156) are the result of meteorological hazards—tropical cyclones, floods, thunderstorms, hailstorms and bushfires. In this study, we normalise the weather-related losses to estimate the insured loss that would be sustained if these events were to recur under year 2006 societal conditions. Conceptually equivalent to the population, inflation and wealth adjustments used in previous studies, we use two surrogate factors to normalise losses—changes in both the number and average nominal value of dwellings over time, where nominal dwelling values exclude land value. An additional factor is included for tropical cyclone losses: this factor adjusts for the influence of enhanced building standards in tropical cyclone-prone areas that have markedly reduced the vulnerability of construction since the early 1980s.

Once the weather-related insured losses are normalised, they exhibit no obvious trend over time that might be attributed to other factors, including human-induced climate change. Given this result, we echo previous studies in suggesting that practical steps taken to reduce the vulnerability of communities to today’s weather would alleviate the impact under any future climate; the success of improved building standards in reducing tropical cyclone wind-induced losses is evidence that important gains can be made through disaster risk reduction.

The text of the paper includes this discussion:

The collective evidence reviewed above suggests that societal factors – dwelling numbers and values – are the predominant reasons for increasing insured losses due to natural hazards in Australia. The impact of human-induced climate change on insured losses is not detectable at this time. This being the case, it seems logical that in addition to efforts undertaken to reduce global greenhouse gas emissions, significant investments be made to reduce society’s vulnerability to current and future climate and the associated variability. Employing both mitigation and adaptation contemporaneously will benefit society now and into the future.

We are aware of few disaster risk reduction policies explicitly developed to help Australian communities adapt to a changing climate, yet disaster risk reduction should be core to climate adaptation policies (Bouwer et al., 2007). . .

An increased threat from bushfires under human-induced climate change is often assumed. Indeed Pitman et al. (2006) and others anticipate an increase in conditions favouring bushfires. However, analyses by McAneney (2005) and Crompton et al. (in press) suggest that the main bushfire menace to building losses will continue to be extreme fires and that the threat to the most at-risk homes on the bushland– urban interface can only be diminished by improved planning regulations that restrict where and how people build with respect to distance from the forest. Disaster risk reduction of this kind would immediately reduce current and future society’s vulnerability to natural hazards.

Climate Models Fail Again! Scientists ‘Startled’ to Discover 50% of Ozone Destroyed in Lower Atmosphere

June 27, 2008 By Paul

Large amounts of ozone — around 50% more than predicted by the world’s state-of-the-art climate models — are being destroyed in the lower atmosphere over the tropical Atlantic Ocean. This startling discovery was made by a team of scientists from the UK’s National Centre for Atmospheric Science and Universities of York and Leeds. It has particular significance because ozone in the lower atmosphere acts as a greenhouse gas and its destruction also leads to the removal of the third most abundant greenhouse gas; methane.

Professor Alastair Lewis, Director of Atmospheric Composition at the National Centre for Atmospheric Science and a lead scientist in this study, said: “At the moment this is a good news story — more ozone and methane being destroyed than we previously thought – but the tropical Atlantic cannot be taken for granted as a permanent ‘sink’ for ozone.

Professor John Plane, University of Leeds said: “This study provides a sharp reminder that to understand how the atmosphere really works, measurement and experiment are irreplaceable. The production of iodine and bromine mid-ocean implies that destruction of ozone over the oceans could be global”.

More Opinion on Global Warming this Sunday on Channel 9

June 27, 2008 By jennifer

Some of the personalities regularly featured on this blog will be on Australian television this Sunday morning talking with journalist Adam Shand about global warming.

The feature story on the Channel 9 Sunday Program will include comment from Tim Flannery, Robyn Williams, Don Aitkin and myself.

I gather the story could be on anytime from 7.30am – the program runs for a couple of hours.

Update June 28

From the Sunday Program website:

Questioning Science
Reporter: Adam Shand

The theory of anthropogenic, or man-made, global warming has become an unchallengeable fact, a piece of black letter law almost unique in the world of science.

Proponents of the theory say the time for scientific debate is over. It would irresponsible to fund any further research into counter views on the relationship between elevated levels of carbon dioxide and a rise in temperatures since the mid-1970s.

It’s regarded as career suicide for scientists to advocate any counter view of the causes of global warming, let alone deny the orthodox consensus view as adopted by the United Nations’ Intergovernmental Panel on Climate Change.

However, there is a school of thought that our knowledge of climate systems is as yet insufficient to be so conclusive on the causes of global warming.

Today Sunday examines the political consensus building that has portrayed global warming as the most urgent crisis humankind has ever faced.

Skeptics point to the gaps in the knowledge base and the flaws in the measurement of vital climate and weather data upon which the consensus is based.

Social researchers also highlight the dangers of conducting science as a form of religion, divided into believers and deniers.

They warn that as governments prepare to make expensive policy decisions, such as carbon emissions trading schemes, this consensus may not reflect the best science.

Fire Under the Arctic Ice

June 26, 2008 By Paul

An international team of researchers was able to provide evidence of explosive volcanism in the deeps of the ice-covered Arctic Ocean for the first time. Researchers from an expedition to the Gakkel Ridge, led by the American Woods Hole Oceanographic Institution (WHOI), report in the current issue of the journal Nature that they discovered, with a specially developed camera, extensive layers of volcanic ash on the seafloor, which indicates a gigantic volcanic eruption.

“The Vesuvius erupted in 79 AD and buried thriving Pompeii under a layer of ash and pumice. Far away in the Arctic Ocean, at 85° N 85° E, a similarly violent volcanic eruption happened almost undetected in 1999 – in this case, however, under a water layer of 4,000 m thickness.”

The Times: New Ice Age is On The Way

June 26, 2008 By Paul

‘Climate: New ice age is on the way.’ That was a headline from The Times newspaper on 21st October 1972.

On 23rd March 1970 the headline read: ‘Antarctic may be key to ice ages.’ According to Dr A T Wilson of Wellington University, New Zealand, the Antarctic may once again be approaching the point of instability at which an ice age is triggered off.

How do I know? The Times Archive invites you to explore 200 years of history as it appeared in the original pages of The Times newspaper from 1785-1985.
