The U.K. Telegraph reported on October 31st that leading environmental campaigners have performed a u-turn on two key technologies they have opposed for decades by openly calling for greater use of nuclear power and genetically modified crops …
Ofcourse the Australian Environment Foundation was ahead of its time. More about the AEF here … http://aefweb.info/

ON Friday 29 October 2010, The Cairns Post reported on the recently released Climate Change Report with respect to impacts on the Far North Queensland region. One of the statements contained in the article was:
“The number of days over 35C in Cairns is expected to triple and the Gulf and Cape can expect longer drier spells interrupted by more intense rainfall.”
If we just focus on the number of days over 35C statement, then how is this qualified? The words “expected to triple” are with respect to what baseline? How is this expectation derived, from historical data or models? The historical data can easily be checked by downloading the records for Cairns from the BOM website (http://www.bom.gov.au).
The results are shown in Figure 1, Temperatures for Cairns above 35°C from 1943 to present.
The long term average number of days above 35°C is 3 per year. There have been four years in the past (1956, 1971, 1988 and 1992) when the number of days has trebled or more above the long term yearly average. It can therefore be expected that this may occur again in the future as part of the natural variation; in fact looking at the frequency of these events, Cairns is overdue for another one of these above average years. The interesting question is should this not occur for say the next 10 years, does this refute the expectation being reported in this newspaper article? Does this graph in fact support the concept that there has been a lack of evidence for warming in the Cairns region since 1996 and is the natural climate cycle in this region still operating within an historical range? Is there justification for an alternative view that the climate in Cairns may be moving into a cooling phase? As usual only time will tell.
Returning to the use of the unqualified word such as “expected”, what does this mean? There is no probability assigned to this descriptor. Yet based on the historical data a probability can be assigned to the hypothesis of a trebling of the number of days with temperatures above 35°C from the long term average for Cairns. According to the records this value is 0.06 (or a 6% chance). Ironically there is twice as much chance (14.7%) that there will be no days above 35°C.
The warmest period for Cairns shown in Figure 1 is from 1988 to 1995, and currently 2010 has reached the long term average of 3 days above 35°C. With the current La Nina pattern in effect it will be interesting to see what maximum temperatures are recorded for November and December of 2010. At this stage it is clear that the 2000’s have not shown any unprecedented warming in the Cairns region based on this maximum temperature parameter.

The Future of the Murray Darling Basin
Dr Jennifer Marohasy | Dr John Williams | Sydney
Writer, biologist and founding member of the Australian Environment Foundation, Dr Jennifer Marohasy will debate the future of the Murray Darling Basin with commissioner of The Natural Resources Commission, Dr John Williams.
The NRC reports to the NSW Premier on a range of natural resource management issues including land, water, and biodiversity. Dr Williams is also a member of the Wentworth Group of Concerned Scientists.
Alarmed that public policy on environmental issues is increasingly driven by moral crusading rather than objective science, Jennifer seeks to provide a counterpoint in public debate.
Monday, 15 November, 6pm for refreshments, 6:30pm – 7:30pm – Talk including Q&A

The Australian Environment Foundation today launched an online petition opposing the federal government’s “Carbon Pollution Reduction Scheme”. The petition will eventually be presented to Parliament by Dr Dennis Jensen, MHR for Tangney.
AEF Chair Dr Jennifer Marohasy said there is a strong need for the petition because none of the major political parties are offering an alternative to carbon trading.
“To quote John from Cheltenham, Victoria, one of the early signatories, ‘At last a chance to protest, a chance to be heard, a chance for the millions of Australians who have not fallen for this propaganda to speak out’.”
Dr Marohasy said that many Australians oppose this scheme because they know it will cost them and their families dearly, sending Australian industries and Australian jobs overseas. It is flawed and won’t have a measurable impact on CO2 levels or global temperature.
“As Chris from Roma in Queensland says, it is ‘Unnecessary and impotent’.
“That’s why even before the petition is launched we have almost 1,000 signatures.”
Dr Marohasy said there were clear themes that emerged from comments left on the petition, and rather than speak for the signatories, they should speak for themselves.
THIS is not what President-elect Barack Obama’s energy and climate strategists would want to hear. It would be anathema to Al Gore and other assorted luminaries touting renewable energy sources which in one giant swoop will save the world from the “tyranny” of fossil fuels and mitigate global warming. And as if these were not big enough issues, oilman T. Boone Pickens’ grandiose plan for wind farms from Texas to Canada is supposed to bring about a replacement for the natural gas now used for power generation. That move will then lead to energy independence from foreign oil.
Too good to be true? Yes, and in fact it is a lot worse, according to Peter Glover and Michael Economides writing in the Energy Tribune. Their article continues:
Wind has been the cornerstone of almost all environmentalist and social engineering proclamations for more than three decades and has accelerated to a crescendo the last few years in both the United States and the European Union.
But Europe, getting a head start, has had to cope with the reality borne by experience and it is a pretty ugly picture.
