Update August 1, 2010 - There will be a federal election in Australian on August 21, 2010.  Neither of the major parties has a serious climate change policy.   ‘Least-worst climate policy?’ by Jennifer Marohasy at Quadrant Online.

Update June 21, 2010 - I am back publishing in the peer-reviewed literature.  First article for a while:  ‘Accessing environmental information relating to climate change: a case study under UK freedom of information legislation’, by John Abbot and Jennifer Marohasy, Environmental Law and Management, Issue 1, Volume 22 [2010]. 

Update December 12th, 2009 -  Jennifer Marohasy is no longer regularly posting at this weblog.   But occasionally posts information from friends at the community thread [ http://jennifermarohasy.com/blog/category/community/ ].   Dr Marohasy is still writing for The Land and some of her columns for this and other newspapers can be read at her website [ http://jennifermarohasy.com/articles.php ].

Dr Marohasy was publically documenting discrepancies – including incomplete data sets being used by top UK climate scientists that spuriously support the case for global warming – before the now infamous emails from the Climate Research Centre in the UK were leaked.  She gives informative and entertaining talks on global warming and other environmental issues [ http://jennifermarohasy.com/display/speaker.html ].

I NEVER met Professor Endersbee, but we corresponded by email.

He contacted me about six years ago when I was working on the Murray River and water issues. He expressed concern about Australia’s great artesian basin and over extraction of what he considered a finite resource.

We later corresponded over climate change issue. Lance believed we must try harder to understand the causes of natural climate change instead of assuming anthropogenic global warming. He was particularly interested in the oceans as a source of carbon dioxide. On June 24, 2009 he wrote:

“The relationship between CO2 and ocean temperature is ordained by the solubility relationship.   I attach [see above] a chart showing my experience curve for the only reliable temperature records we have. It is difficult to argue against a correlation of 0.99.   Read more »

IT is generally agreed that the worst dust storms since European settlement were during the 1944-1945 period.  

In his book Out of the West: A Historical Perspective of the Western Division of NSW, former Western Lands Commissioner, Dick Condon, says there were 34 severe dust storms at Wagga Wagga during the period 1944-45, many so bad that it would have been necessary to turn the lights on in order to see inside the average sized house.  

Mr Condon suggests the dust storms during the 1982-83 drought were not as bad as those during the period 1885 to 1945 because of the much improved conditions of the landscape in the semi-arid and arid grazing country in western New South Wales.

In contrast, it is generally agreed that bushfires are getting worse.   Read more »

EARLY  Wednesday morning a 8.3 magnitude earthquake caused a tsunami in the Pacific, killing at least 140 people in Samoa and Tonga. Later in the day a 7.6 magnitude earthquake hit western Sumatra in Indonesia, drowning hundreds of people and burying thousands more under rubble.

Many in Samoa claim the warning system in place failed because an alert was only received after the tsunami hit.  The official line has been that when the earthquake is close to land, the technology is such that there is simply not time for adequate warnings.  

Brisbane-based engineer, now publisher, John McRobert, disputes this assessment claiming major earthquakes have precursor seismic shocks hundreds of kilometres below the Earth’s surface, and the transmigration of the energy, and the path to the surface can be accurately predicted: Read more »

THE United Nation’s Intergovernmental Panel on Climate Change (IPCC), and most others who believe in anthropogenic global warming (AGW), have been influenced by the work of climatologists relying on tree-ring data to reconstruct past climate because the thermometer record only goes back to about 1850.  The claim that there has been an unprecedented upswing in temperatures over the last 100 years making 1998 the hottest year of the last thousand years, has for example, been based on reconstructions from tree-ring data.

In response to recent suggestions by Canadian statistician Steve McIntyre that the official reconstructions may have been fudged, Keith Briffa, from the Climate Research Unit associated with the UK Met. Office, has responded explaining that there was no cherry picking of data in the development of the reconstructions used by the IPCC and others, rather, the methodology is not yet robust.  

Given this admission from a leading UK climate scientist, it would perhaps be appropriate for the head of the IPCC, Rajendra Pachauri,  to now advise world leaders that there are potential problems with the methodology used in the development of key assumptions underpining the consensus view on anthropogenic global warming and that until further notice, the big meeting in Copenhagen should be postponed.

MOST scientific sceptics have been dismissive of the various reconstructions of temperature which suggest 1998 is the warmest year of the past millennium.    Our case has been significantly bolstered over the last week with statistician Steve McIntyre finally getting access to data used by Keith Briffa,  Tim Osborn  and Phil Jones to support the idea that there has been an unprecedented upswing in temperatures over the last hundred years –  the infamous hockey stick graph.  

Mr McIntyre’s analysis of the data – which he had been asking for since 2003 – suggests that scientists at the Climate Research Unit of the Hadley Centre associated with the UK Met. Office  have been using only a small subset of the available data to make their claims that recent years have been the hottest of the last millennium.   When the entire data set is used, Mr McIntyre claims that the hockey stick shape disappears completely. [1]    

Mr McIntyre has previously showed problems with the mathematics behind the ‘hockey stick’.   But scientists at the Climate Research Centre (CRU), in particular Dr Briffa, have continuously republished claiming the upswing in temperatures over the last 100 years is real and not an artifact of the methodology used – as claimed by Mr McIntyre.     However, these same scientists have denied Mr McIntyre access to all the data.    Recently they were forced to make more data available to Mr McIntyre after they published in the Philosophical Transactions of the Royal Society  -  a journal which unlike Nature and Science has strict policies on data archiving which it enforces.   Read more »

MOUNTAIN glaciers in Asia are melting at a rate that could eventually threaten water supplies, irrigation or hydropower for 20 percent to 25 percent of the world’s population: that is according to the latest United Nations Environment Program report.

Lester Brown of the Earth Policy Institute puts it this way, “The melting of the glaciers in the Himalayas and on the Tibetan Plateau will deprive the Indus, Ganges, Yangtze and Yellow rivers of the ice melt that sustains their flow during the dry season and the irrigation systems that depend on them.”

But according to Patrick Moore, co-founder of Greenpeace, it’s a case of cognitive dissonance.  He explains:

“In other words the supply of melt water from the melting glaciers is threatened by the melting of the glaciers. This is correct in that if the glaciers melt completely there will be no more melt water from the glaciers.

“What if the glaciers were not melting due to a colder climate? Then where would the irrigation water come from? How about if the glaciers were advancing 100 meters per year toward the villages that need the melt water for irrigation?   Read more »

“MITCHELL Taylor is a Polar Bear researcher who has caught more polar bears and worked on more polar bear groups than any other, but he was effectively ostracized from the Polar Bear Specialist Group (PBSG) specifically because he has publicly expressed doubts that there is a crisis due to carbon dioxide emissions. 

“Dr Andy Derocher, the outgoing chairman of the PSBG and Professor at the University of  Alberta, wrote to inform Taylor that he was not welcome at the 2009 meeting of the PBSG.

“Keep in mind as you read his comments (below) that Taylor had arranged funding to attend the meeting in Copenhagen, and has been at every meeting of this group since 1981. With 30 years of experience in polar bear research, it goes without saying that he has something to contribute to any discussion about polar bear conservation. This is the original email from Derocher to Taylor explaining why he was not invited:    Read more »

“CORAL atolls have proven over thousands of years that, if left alone, they can go up and down with any sea level rise. And if we follow some simple conservation practices, they can continue to do so and to support atoll residents. But they cannot survive an unlimited population increase, or unrestricted fishing, or overpumping the water lens, or unrestrained coral mining.”

These are the conclusions from Willis Eschenbach who lives in Honiara, Solomon Islands.  He explains why: Read more »

“IN order for increased human carbon dioxide emissions to cause accelerated global warming, the climate models need to assume that carbon dioxide remains in the atmosphere for a very long time, up to 100 or more years.  Read more »
