No Place for Climate Sceptics

October 29, 2008 By admin

How Melbourne’s Climate Has Changed: A reply to Dr David Jones (Part 3)

October 25, 2008 By jennifer

IN an opinion piece entitled ‘Our hot, dry future’ published by Melbourne’s The Age newspaper on October 6, 2008, Dr David Jones, head of climate analysis at the Australian Bureau of Meteorology, suggested global warming was responsible for the current long drought in Melbourne and that there was worse to come.  

I don’t think the article was very convincing. I am annoyed that it didn’t include any real data.  While Dr Jones claimed that “We know that over the past 11 years Melbourne’s rainfall has been about 20% below the long-term average”, he didn’t explain what period this “long-term average” covers and what is the relevance of the last 11 years given it is accepted that over this period there has been a dominance of El Nino, and therefore dry conditions.   

Key Australian Institutions have claimed for some time that we have a water crisis because of climate change. 

Indeed in 2005 CSIRO published a “Melbourne Water Climate Change Study” claiming  “…the greater Melbourne Region has had its lowest rainfall on record compared to all other periods of similar length.” 

But as blogger, Warwick Hughes, showed some time ago, the period chosen was just 92 months, from October 1996 to May 2004.

In order to put their statement in some context Mr Hughes graphed high quality rainfall data for the weather station closest to Melbourne, Yan Yean, back to January 1863 – and he has just updated the chart to the end of September 2008. 

A high quality version of this chart can be found at Mr Hughes’ website, click here.

The chart indicates that Melbourne experiences dry periods every so often and that the current drought is similar in magnitude to the droughts of 1896, 1925 and 1945.  The chart showing 145 years of data, does not support the claim, made by Dr Jones in his article in Melbourne’s The Age, that there has been recent unusual climate change in Melbourne.  Indeed periods of drought and flood are a natural hazard.

GM Crops Implicated in Global Warming

It is absurd to suggest that genetically modified plants could influence the global climate, but the ABC, the public broadcaster in Australia, has suggested as much: read more here.

Skeptics to Gather in New York Again

October 24, 2008 By jennifer

A highlight of my year so far is the climate change conference in New York in March.    It was a gathering of more than 500 skeptics, including many scientists, to discuss global warming. 

I was enthralled by a presentation from Stan Goldenberg from NOAA which included photographs taken inside the eye of hurricanes from flights within NOAA’s Hurricane Hunters – WP-3D Turbo Prop Aircraft.

Now there are plans to hold a second conference on March 8-10, 2009, once again in New York City.

According to the press release:

The 2009 International Conference on Climate Change will serve as a platform for scientists and policy analysts from around the world who question the theory of man-made climate change. This year’s theme, ‘Global Warming Crisis: Cancelled’, calls attention to new research findings that contradict the conclusions of the latest Intergovernmental Panel on Climate Change (IPCC) report.

Hosting the conference for the second consecutive year will be The Heartland Institute, a 24-year-old national nonpartisan think tank based in Chicago. “All of the event’s expenses are being covered by individual and foundation donors to Heartland,” said Dan Miller, executive vice president of the institute. “No corporate dollars earmarked for the event were solicited or accepted.”

“Last March we proved that the skeptics in the debate over global warming constitute the center or mainstream of the scientific community, while the alarmists are on the fringe,” said Heartland President Joseph Bast. “In the past six months, the science has grown even more convincing that global warming is not a crisis. Opinion polls and political events, including the defeat of ‘cap-and-trade’ legislation in the U.S. Senate, also suggest this ‘crisis’ is over. It has been cancelled by sound science and common sense.”

Campaigning for National Parks is Against Australian’s Bush Ethos: Part 1, Buying Back Tooralee

October 22, 2008 By jennifer

THERE has been much written about Australia’s national character emerging from a bush ethos: the idea that a specifically Australian outlook emerged first amongst workers in the Australian outback.  Banjo Paterson, perhaps more than any other writer, created and defined this cultural heritage.  His story about the shearer and his sheep (the jumbuck) remains our most popular national song, ‘Waltzing Matilda’.  I grew up on ‘The Man from Snowy River’; a poem about a courageous young horseman who out-rides wild brumbies in the High Country.  

But few Australians now have anything much to do with the bush.  They mostly live in cities, don’t know how to ride a horse and go to the beach for their holidays.  They just singing about sheep at sporting events and read poems about mighty rivers and like the idea of saving the outback.  And so it seems every new Australia government makes saving the Murray River part of their platform. 

The previous Howard government was going to save the Murray from salinity – and achieved this through the construction of salt interception schemes and catchment wide drainage plans all administered by the Murray Darling Basin Commission.     

The new Rudd Government wants to save the Murray from climate change.   This is a much more ambitious undertaking than saving the Murray from salt.  

As part of this campaign the new government has new legislation, The Water Amendment Bill 2008, and it is currently being debated in federal parliament with its second reading beginning last week.   A centre piece of the new legislation is the creation of a ‘The Murray Darling Basin Authority’.   This new institution is claimed to be needed because the existing Murray Darling Basin Commission doesn’t have enough control over the states, but in reality the new organisation, like the old, will still be subject to state politics.  In short, nothing much will change, but it keeps the politicians in politics.   

Politician and new Climate Change Minister, Penny Wong, plans to relieve the claimed climate change problem by buying up farms; most recently through the purchase of a 91,000 hectare property called Tooralee near Burke in NSW.  Tooralee currently grows maize, cotton and beef cattle but following the federal government takeover will be converted to national park.  

Internet campaigners ‘GetUp’ helped get the Rudd-government elected, and have recently joined ‘the fray’ on Murray River issues claiming to provide an opportunity for Australians “to keep the rivers flowing” and save “Australia’s food bowl” through a few mouse-clicks.   But this new campaign is particularly deceptive as Penny Wong’s policies will actually close-down agriculture in the Murray-Darling Basin i.e. empty the food bowl!  Indeed the federal government has something like $3.6 billion to buyback farms like Tooralee.
Furthermore, as some farmers explained on ABC’s TV’s Four Corners program on Tuesday night, you can’t buy back rivers, not even with billions of dollars, because water allocations are just air space until it rains.   

But hey, modern Australia’s are now a mostly soft and gullible lot and likely to support this campaign which is essentially a campaign in support of more politics and big government and against bushies because they now know no better.   But none of this makes senses in the context of our heritage which was about being practical and a part of the bush – the floods and the droughts and the climate change.
