Australia’s university campuses are hostile to free speech

“IPA research has found a worsening state of free speech on Australia’s university campuses. The IPA’s Free Speech on Campus Audit 2017 found 34 of Australia’s 42 universities are hostile to free speech on campus through their actions and policies.” click here

Random Noise Included in Australian Temperature Measurements

“What we have is 20 years of incomplete raw data that includes random noise recorded from instruments that are nothing like the ones used for about eight of the last ten decades in Australian climate history. Somehow we are supposed to connect that data together?” click here

Increasing Energy Prices Undermine Infrastructure Sustainability

“Glencore and other major players in Australia’s mining and heavy industry sectors are threatening to shut mines and factories, and divert all investment elsewhere, unless Aussie energy prices fall back to internationally competitive levels.” click here

Roof-Harvested Rain Water Poses Risks for Legionella and Mycobacterium

Hamilton KA, Ahmed W, Toze S, Haas CN. Human health risks for Legionella and Mycobacterium avium complex (MAC) from potable and non-potable uses of roof-harvested rainwater. Water research. 2017 Apr 5;119:288-303. doi: 10.1016/j.watres.2017.04.004.

A quantitative microbial risk assessment (QMRA) of opportunistic pathogens Legionella pneumophila (LP) and Mycobacterium avium complex (MAC) was undertaken for various uses of roof-harvested rainwater (RHRW) reported in Queensland, Australia to identify appropriate usages and guide risk management practices. Risks from inhalation of aerosols due to showering, swimming in pools topped up with RHRW, use of a garden hose, car washing, and toilet flushing with RHRW were considered for LP while both ingestion (drinking, produce consumption, and accidental ingestion from various activities) and inhalation risks were considered for MAC. The drinking water route of exposure presented the greatest risks due to cervical lymphadenitis and disseminated infection health endpoints for children and immune-compromised populations, respectively. It is therefore not recommended that these populations consume untreated rainwater. LP risks were up to 6 orders of magnitude higher than MAC risks for the inhalation route of exposure for all scenarios. Both inhalation and ingestion QMRA simulations support that while drinking, showering, and garden hosing with RHRW may present the highest risks, car washing and clothes washing could constitute appropriate uses of RHRW for all populations, and toilet flushing and consumption of lettuce irrigation with RHRW would be appropriate for non- immune-compromised populations.

Australia is well on its way to energy poverty

“A combination of green inspired state moratoria on gas exploration, coupled with growing gas export capacity, and politically motivated closures of coal plants, has created a looming shortfall in Australian energy supply.”  click here

Solar homes use more grid energy than non-solar homes, Australia

“There are probably more solar panels in QLD than anywhere else in the world. Back in February last year, the boss of the Queensland state power company announced the awkward result that households with solar panels were using more electricity than those without. Apparently people without solar were turning off the air conditioner because electricity cost too much, but the solar users didn’t have to worry about the cost so much.” click here
