Aussie skeptics say they have one of their nation’s top climate alarmist professors cornered in an ongoing battle of words over who holds the high ground on scientific integrity. Scientist, Dr Judy Ryan and her colleague, Dr Marjory Curtis are going public with a series of damning emails they’ve had with government-backed promoters of fears about man-made global warming.
Their latest target is Professor David Karoly, a climatologist who they claim dishonestly championed a government campaign to depict human carbon dioxide (CO2) emissions as black smoke, contrary to scientific fact.
Dr Ryan reports, “On 18th February 2014 I sent an email to David Karoly with Marjory Curtis, a retired geologist, as my co-signer. Approximately 180 australian and overseas media outlets, politicians, universities, including their student newspapers, and prominent climate hysteria mongers were openly copied in.”
Ryan and Curtis are among many highly-qualified scientists who, as skeptics of the wrong-headed hysteria over supposed man-made global warming, are fighting to restore scientific integrity.
Dr Curtis says Karoly’s “error” over the CO2 as black smoke “may have been a fortuitous oversight” for the cause of alarmists who some say are trying to dupe the public on the issue.
Judy Curtis has advised Karoly all the correspondence, because of its significance to public policy, will be published as open letters. She says, “We replied 21st February and added in our fellow skeptics. So there are now close to 220 observers for Karoly’s next response. To date we have not heard back, but it is early days yet.”

It was the world’s most famous case of “AIDS.” In June 1984, actor Rock Hudson, the good-looking, crew-cut symbol of perfect American manhood, received his diagnosis of the new syndrome, based on a “positive” result on a test that had been on the market for less than two months.
Those are just some of the species the Revive & Restore “de-extinction” project has under consideration. The California Grizzly Bear, the Carolina Parakeet, the Tasmanian Tiger and Steller’s Sea Cow are also mentioned as potential candidates for revival. Presumably, all the “de-extincted” species are meant to again freely roam the Earth and in large numbers.

But it’s not so strange when you consider the larger message that made Sagan famous.
The recently uncovered work, written in 1931, is reminiscent of a theory championed by British astrophysicist Fred Hoyle nearly 20 years later. Einstein soon abandoned the idea, but the manuscript reveals his continued hesitance to accept that the Universe was created during a single explosive event.
Editor’s Introduction: With another review of the Renewable Energy Target commencing we felt it was important to revisit the results of a modelling exercise assessing potential wind power grid integration technical issues undertaken by the Australian Energy Market Operator back in late 2013. This study attracted little attention but gave strikingly different answers to prior modelling exercises, suggesting greater grid integration costs for levels of wind consistent with achieving the Renewable Energy Target. While this study was fine for its purpose of helping AEMO to explore potential technical changes that might be required to manage high levels of wind penetration, it made simplifying assumptions that made it unsuitable for assessing the likely economic costs of achieving the Renewable Energy Target. To head off the potential for this study to be misinterpreted and misused in the forthcoming review of the Renewable Energy Target, we asked Jenny Riesz to provide this review of the report.
AEMO’s Wind Integration Studies report, released in late 2013, suggests that technical constraints and grid limitations could lead to the significant curtailment by 2020 of around 35 per cent of the wind energy generated in Victoria, and around 15 per cent of the wind energy generated in South Australia.
Have other studies failed to capture the impact of grid constraints that mean meeting the 41,000 GWh Renewable Energy Target will be much more expensive than we thought?
