CLIMATE, CLIMATE, CLIMATE -- Still

The looming destruction from foolish government climate policies is still focusing a lot of minds in Australia. Today's offerings lead off with three articles on climate issues -- and a cartoon to check out

Zeg on climate

In his latest offering, conservative Australian cartoonist ZEG almost feels sorry for Kevvy Rudd -- seeing the pickle that his climate follies have got him into.

High costs of Rudd's climate policies not being acknowledged

You can't blame politicians for being wary about levelling with the voters. From Norman Tebbit's exhortation to the unemployed in Thatcher's Britain to get on their bikes to Malcolm Fraser's observation that life wasn't meant to be easy, unpalatable truths don't go down so well. And that was in the class-bound politics of the 1970s. Now, in the era of post-materialism, the politician's tendency to avoid being the bearer of bad tidings has become more pronounced.

Labor is still basking in the glow of ratifying the Kyoto Protocol and burnishing its environmental credentials while pushing ahead with the task of introducing emissions trading in 2010. But there is a growing disconnect between the politics and the policy of climate change. The Rudd Government is eschewing telling Mr and Mrs North Ryde what saving the planet will mean for them.

Emissions trading will reach into every nook and cranny of the economy, changing the prices of all manner of goods and services with flow-on effects for incomes and jobs. Yet so far this has been largely a business story as industry groups have highlighted the economic impact of the design choices cabinet is pondering. The Government has avoided broader debate by promising to cut the fuel excise to offset the impact of emissions trading on petrol prices for at least the first three years of the scheme. Thus has the vital issue been (temporarily) defused. This was probably the political price that had to be paid for introducing emissions trading.

But the pity is that it shows the Government is unwilling to tell voters how they will have to change their behaviour if they really want to save the planet. Let's dig a bit deeper into petrol and cars to illustrate the magnitude of these changes. The Government is likely to adopt a target of reducing Australia's greenhouse gas emissions by 20 per cent of 2000 levels by 2020. Passenger vehicles in Australia emitted 42.6 million tonnes of carbon dioxide equivalent gases in 2006. A "20 by 2020" target would require their emissions to be cut to 33.1 million tonnes by 2020.

The amount of greenhouse gases pumped into the atmosphere by car owners depends on how far they drive and how efficient their cars are. To get emissions down to 33.1 million tonnes by 2020 by driving less would involve everyone with a licence today getting on their bikes for one in every five kilometres and everyone who reaches driving age from today hitch-hiking. In fact, distances travelled in cars will rise as population and incomes grow. The Department of Climate Change projects that the distance travelled will increase by 20 per cent by 2020.

So will the target be met from driving more fuel-efficient cars? The average fuel efficiency of cars on Australia's roads in 2006 was 11.4 litres for every 100 kilometres. Taking into account the projected increase in distances travelled, arriving at the 2020 target by driving more abstemious vehicles would require improving average fuel efficiency to 6.7 litres per 100 kilometres. That would be the equivalent of replacing every one of the 14 million cars on the roads now with a Toyota Yaris.

We hear a lot about people turning to smaller cars because of high petrol prices. Yet in the past couple of years, average fuel efficiency of Australian cars has deteriorated. The department's projections - which assume a slowdown in the rate of growth in distance travelled, modest improvements in fuel efficiency and modest falls in petrol prices - show that if we continue with business as usual passenger vehicles will emit 49.3 million tonnes in 2020. That will be 20 per cent higher than 2000 levels.

Under the Government's emissions trading scheme there will be a limit on overall emissions. If cars overshoot the target, other sectors will make deeper proportionate cuts. The price of carbon will rise until it becomes cheaper to cut emissions. Economists reckon every 10 per cent rise in petrol prices will see car owners reduce their fuel consumption by 4 per cent in the long run. Petrol prices are already up 40 per cent since 2002. If we are to rely on prices alone to achieve the cuts in fuel consumption needed to meet the 2020 target, petrol prices will need to go up another 15 per cent.

The bottom line? Get on your bike. Or pay more. Saving the planet wasn't meant to be easy.

Check the climate facts before you believe the climate prophecies

By Jennifer Marohasy (An expert on water issues in the Murray/Darling system)

When Nicholas Stern released his influential British government report on the economics of climate change in October 2006, it said that the east coast of Australia had suffered declining rainfall. In the same year, the Howard government pledged an additional $500 million to stop the trend of rising salinity in the Murray River.

Three claims have been repeated so often they are accepted as fact: global temperatures are rising, we have less rainfall and so water is becoming scarce, and salinity in the Murray River is rising.

Of course there is the old adage: lies, damn lies, and then there are statistics. But we can keep it simple and just consider data from observations of the real world and from the most reputable institution since records began for the particular issue in which we are interested. It is important to not confuse real-world data (also known as observational data) with output from computer models because computer models generate scenarios that may or may not come true.

Observational data on rainfall for the entire east coast of Australia is available from the Australian Bureau of Meteorology with yearly averages for all the sites back to 1900. But, contrary to the Stern report, this chart does not show declining rainfall; rather, it indicates that rainfall was very low in the early 1900s, that there were some very wet years in the late '50s and early '70s, and overall the trend is one of a slight increase in rainfall during the past 107 years. Stern got it wrong, perhaps because he was confusing output from computer models with the real-world data. There are a lot of computer models that foretell dire environmental catastrophe that may not eventuate.

Rainfall data for the Murray-Darling Basin is also available from the Bureau of Meteorology. The overall trend is one of increasing rainfall since 1900. The past few years show below-average rainfall for the region and indeed there has been drought. The low river inflows have been exacerbated by more groundwater pumping, more plantation forestry, including in the upper Murrumbidgee, and more salt interception schemes along the Murray River.

Salt interception schemes evaporate water to trap the salt. In the '80s, computer models predicted that Adelaide's drinking water soon would be too salty to drink because of declining water quality and rising salinity levels in the Murray River. Measurements of salinity are recorded from many different sites along the Murray River, including at Morgan, which is immediately upstream from the offshoots from Adelaide's drinking water. The data from Morgan enables us to get an idea of how salt levels are trending in the real world, as opposed to computer-generated scenarios.

Concerns with salinity have resulted in levels being tested from the '30s. Salinity levels rose dramatically during the '70s and peaked at Morgan in 1982, which was a drought year. Then the Murray-Darling Basin Commission implemented a catchment-wide drainage management plan and started building salt interception schemes, and since then salinity levels have more than halved.

Measuring global temperatures is much more contentious than measuring salinity or rainfall. Issues include how to combine the data from all the weather stations across the globe and the data is usually presented as a temperature anomaly rather than, for example, just a global average. A temperature anomaly is derived from the average temperature for a specific but arbitrarily defined period and usually emphasises the extent to which temperatures have increased. The Bureau of Meteorology relies on the Climatic Research Unit at the University of East Anglia in conjunction with the Hadley Centre of the British Met Office for its information on global temperatures. This information is available on the internet going back as far as 1850 and shows the deviation from the period 1961 to 1990.

But when global temperatures are presented just as a simple average with a vertical axis that spans the range of temperatures experienced in a place such as Ipswich (west of Brisbane) during a single year, the global rise in average temperatures is not that obvious because the mean temperature since 1850 has increased by less than 1C.

The data from the CRU is generally accepted as accurate by those who subscribe to the idea that carbon dioxide is driving dangerous man-made global warming. In contrast, many sceptics of man-made global warming argue that the only reliable measure of global temperatures is from satellites.

Ross McKitrick from Canada's University of Guelph argues that 50 per cent of global warming measured by land-based thermometers in the US since 1980 is due to local influences of man-made structures, also known as the urban heat island effect. There also have been issues with the additions and losses of weather stations; for example, many weather stations were lost in places such as Siberia with the disintegration of the Soviet Union. Thermometer temperature data has been collected in the polar regions only since the '40s and calculating the mean temperature at the poles is still difficult.

James Hansen, from the Goddard Institute for Space Studies, has explained the general difficulty of measuring surface temperatures. "Even at the same location, the temperature near the ground may be very different from the temperature 5 feet (1.52m) above the ground and different again from 10 feet or 50 feet above the ground," he says. "Particularly in the presence of vegetation (say in a rainforest), the temperature above the vegetation may be very different from the temperature below the top of the vegetation. "A reasonable suggestion might be to use the average temperature of the first 50 feet of air either above ground or above the top of the vegetation. To measure SAT (surface air temperature) we have to agree on what it is and, as far as I know, no such standard has been suggested or generally adopted."

Given these difficulties, an alternative is to use temperature data from satellites. Since 1979, orbiting satellites have measured temperature in a completely different way from the traditional method of using thermometers. The satellites measure microwave radiation and the research focus has been on getting a broadly representative measure of lower atmosphere temperature.

The satellite data is available only since 1979, but it does give a good overview of how global temperatures have been trending during the past 30 years. Global temperatures peaked in 1998, associated with an El Nino warming event, then dropped quite dramatically before stabilising for a few years and dropping again recently. The satellite data on global temperatures indicates we presently have a global cooling, not a global warming, trend.

Many scientists, environmental activists and politicians have staked their reputations on the idea that global temperatures are going to keep steadily rising, so it is not surprising that they are ignoring the past few years of data from the satellites. But the stakes are very high. The Australian Government is planning to introduce an emissions trading scheme, also described as a carbon pollution reduction scheme, on the basis that that carbon dioxide from the burning of fossil fuels is contributing to dangerous global warming.

Many people assume that such a drastic action is premised on good evidence establishing a proven causal link between anthropogenic carbon dioxide and global warming. But it is not, instead relying on computer models, claims of a scientific consensus and the belief that global temperatures continue to creep higher and higher. Many false claims are made about the state of our environment on an almost daily basis but, because most Australians are illiterate when it comes to science and maths, they are mostly just accepted.

Most Australians rely on television and newspapers for information about environmental issues. If this reporting incorporated some charts, in the same way business reporting does as a matter of course, then there might be at least some quality control. But, ultimately, good policy is going to require that a much larger percentage of Australians having a higher level of scientific literacy. The alternative is important policy continuing to be decided on hearsay rather than evidence because you just can't trust the environmental advocates. Indeed, they may care more about the environment than the truth.

Many people want to save the environment, but few people are confident of interpreting a chart or graph of scientific information on, say, water quality or global temperatures. So, when it comes to environmental issues most Australians just believe what the experts say. After all, people who care about the environment are the good guys, caring and trustworthy.

Furthermore, when it comes to issues such as global warming, we are told there is a consensus, that most scientists agree about most things and this should make us feel even more secure believing what they tell us about the sorry state of planet Earth. But who should check what the experts are saying about environmental issues, and at what point? When it comes to business issues, whether interest rates or commodity prices, we are shown charts, hard data, and people who are interested in the business issues would expect no less.

Environmental issues are very much like business issues: they are about numbers and trends. For example, business analysts are interested in whether the price of oil is going up or coming down and Al Gore tells us that global temperatures are going up. But if your next stock investment depended on what Gore was telling you the business market was doing, wouldn't you also seek information from other sources to be sure?

No, you are not all going to die from warming

By Andrew Bolt

I doubt any shire in Australia has tried as hard as Mornington Peninsula's to terrify ratepayers about global warming. The shire has even sent all residents a booklet, Climate change: What we are doing about it (no link), that warns that many of them could die from global warming over the next few decades:
Average annual temperature will rise by up to 3.5 degrees by 2070, placing greater stress on elderly residents and those living in older homes with inadequate insulation. The increased incidence of exteme heat days and heat waves, in conjuction with a growing and ageing population in the peninsula, has the potential to contribute to significant mortality in future decades...

Potential impacts: Ability to affect entire population, especially elderly and infants; 27,000 elderly, 8000 infants and young people; Increased mortality and morbidity in vulnerable groups.

You don't often come across scaremongering so brazen - or so wildly and irresponsibily exaggerated. Let me try to reassure the poor residents. Let's note, for a start, that that global temperatures haven't actually risen over the past decade. Let's note also that by 2070, we'll be so much richer that we can afford at the very minimum air-conditioners for everyone to save them from this allegedly apocalyptic heat.

But there is one more thing to consider. I had to go to hospital on Thursday and found the waiting time for treatment had blown out to hours. Reason? Winters, not summers, and cold, rather than heat, is what makes us sickest and most fills our hospitals. And we should fear global cooling far more than global warming: Some data? We are more likely to die in winter of temperature-related diseases:

Some data? We are more likely to die in winter of temperature-related diseases:
Bi, P., Parton, K.A., Wang, J. and Donald, K. 2008. Temperature and direct effects on population health in Brisbane, 1986-1995. Journal of Environmental Health ...

Bi et al. report that "death rates were around 50-80 per 100,000 in June, July, and August [winter], while they were around 30-50 per 100,000 in the rest of the year, including the summer," ... (T)he researchers further note that "it is understandable that more deaths would occur in winters in cold or temperate regions, but even in a subtropical region, as indicated in this study, a decrease in temperatures (in winters) may increase human mortality."

We are more likely to die of heart failure in cold weather :
THE winter months bring more than colds and flu, according to research showing people are more likely to suffer heart failure in the chilly season. A team of researchers examined the seasonal differences in hospital admissions and deaths in 2961 patients with chronic heart failure in South Australia over the past decade, and found a striking trend.... "(D)eaths in those diagnosed with heart failure were higher in winter and lowest in summer."

A recent New Zealand study confirms it's chilly days, not warm ones, that are deadliest to the old and very young:
From 1980-2000 around 1600 excess winter deaths occurred each year with winter mortality rates 18% higher than expected from non-winter rates. Patterns of EWM by age group showed the young and the elderly to be particularly vulnerable.

So global warming could actually cause fewer deaths from temperature-related illness:
In a review article published in the Southern Medical Journal, Keatinge and Donaldson (2004) of Queen Mary's School of Medicine and Dentistry at the University of London begin the main body of their text with a clear declaration of the relative dangers of heat and cold when it comes to human mortality: "cold-related deaths are far more numerous than heat-related deaths in the United States, Europe, and almost all countries outside the tropics, and almost all of them are due to common illnesses that are increased by cold.".

So what are the implications of global warming for human mortality? Keatinge and Donaldson state that "since heat-related deaths are generally much fewer than cold-related deaths" - and, we note, are comprised primarily of deaths that typically would have occurred a few weeks later even in the absence of excess heat - "the overall effect of global warming on health can be expected to be a beneficial one." As an example, and even including the early heat-harvesting of naturally-expected deaths, they report that "the rise in temperature of 3.6øF expected over the next 50 years would increase heat-related deaths in Britain by about 2,000 but reduce cold-related deaths by about 20,000."

And residents around Melbourne and such coastal areas actually have little to fear, according to a huge study Climate and mortality in Australia: retrospective study, 1979-1990, and predicted impacts in five major cities in 2030, that even had the alarmist CSIRO involved:
We conclude that the 5 largest Australian cities exhibit climate-attributable mortality in both summer and winter. Given the scenarios of regional warming during the next 3 decades, the expected changes in mortality due to direct climatic effects in these major coastal Australian cities are minor.

Bottom line: more Mornington Peninsula residents are likely to die of fright from their shire's propaganda than are likely to die from global warming. Shame on the shire.

Prominent surgeon accused of botched work

Only 12 years late

A PROMINENT surgeon accused of performing botched, incompetent and unethical operations over more than a decade could face disciplinary action. Toowoomba surgeon Darryl Wayne Bates is also accused of engaging in dishonest behaviour. The Medical Board of Queensland has referred Dr Bates to the Health Practitioners Tribunal alleging a pattern of misconduct by him.

Board documents filed in the District Court of Queensland reveal Dr Bates, who is on the Toowoomba and Darling Downs Medical Association executive committee, was found in an audit of patients by St Vincent's Hospital, Toowoomba, and the Royal Australasian College of Surgeons to have performed "suboptimal" surgery as far back as 1996.

In one operation it is alleged "a loop of intestine was mobilised from the pelvis and left without blood supply and attachment to the gut". The patient, who deteriorated and required further treatment at the Toowoomba Base Hospital, was found to have a 1cm-wide cut in their mid-small bowel by another surgeon.

Further incompetence allegedly took place between August 2003 and September 2005 in four cases at Toowoomba's St Andrew's Hospital, which filed a complaint against Dr Bates to the medical board. On August 14, 2006, he signed an undertaking to have restrictions placed on him by the medical board and later that month was told his conduct was being referred to a Professional Conduct Review panel. He is then alleged to have carried out four operations in January and February this year, contrary to his agreed restrictions.

When contacted by The Courier-Mail, Dr Bates deferred comment to his solicitor Harry McCay. Mr McCay chose not to provide a statement to The Courier-Mail. A directions hearing into Dr Bates's case has been set down for September 1 in the Health Practitioners Tribunal.

Girls, 14, 'rolling condoms on to plastic penises'

EXPLICIT sex-education lessons in WA schools are upsetting Muslims and Catholics. Prominent WA Muslim imam Abdul Jalil Ahmad called the lessons, where girls as young as 14 are rolling condoms on to plastic penises, "pornography in the classroom''. Peter Rosengren, editor of the Catholic Church's The Record newspaper, said such lessons were indicative of society's over-sexualisation of children.

A female Year-10 student from Rossmoyne Senior High School sparked the controversy after coming home distressed, following her participation in a class, as part of the Australian Medical Association's Dr Yes program. The 15-year-old's father, Axel Cremer, was furious his permission had not been sought. "It's outrageous,'' Mr Cremer said of the program, that is taught by medical students to about 10,000 children each year at about 150 public and private schools statewide. "My concern is the ethical standards and moral values of an education system that believes it has the right, without my permission, to get my daughter to put condoms on plastic penises.''

Rossmoyne principal Leila Bothams wrote to Mr Cremer, saying the school would have contacted him, but she had been unaware the program was being run for Year 10s.

Mr Cremer, who is a Muslim and whose daughter is also Muslim asked how many other parents statewide had not been consulted. He said the issue was not religious, but was about moral values. His other non-Muslim daughter was also outraged. Mr Cremer acknowledged students needed to know about sexually transmittable diseases and unwanted pregnancies, but said there were other ways to teach this.

Imam Ahmad said the lessons were "completely evil'' and should be banned by the Government. "That's pornography in the classroom,'' he said. Secular philosophy about sex education was problematic because it only focused on preventing pregnancy and disease, when it should also involve morality.

Mr Rosengren said as a husband and a father he also believed there should be consultation with parents. Issues within sex education -- relationships, intimacy, trust, fidelity and gender -- were the most important aspects of people's lives.

Education Department deputy director-general Margery Evans said the content of the program was consistent with the department's health and physical education syllabus and there were no plans to change it. It was "regrettable'' offence had been caused. But the ``isolated incident'' should be seen in context of thousands of students who had benefited from the program over its 10-year operation. AMA federal president Rosanna Capolingua said demonstrations were necessary because condom failure was often due to a lack of understanding about how they were used
