THE Australian government didn’t get its carbon trading legislation through the Senate last week and has now decided, at least for the moment, to just push ahead with that part of the legislation relating to renewable energy targets.   
It seems this legislation is likely to be passed sometime this week and according to many pundits the big [...]

THERE are four official global temperature data sets and there has been much debate and discussion as to which best represents change in global temperature. 
Tom Quirk has analysed variations within and between these data sets and concludes there is 1. Substantial general agreement between the data sets, 2. Substantial short-term variation in global temperature in [...]

CHAIR of the Australian Environment Foundation, Jennifer Marohasy, today welcomed new research by Australian physicist, Dr Tom Quirk, suggesting natural environmental forces, more than just fossil fuel emissions, could be contributing to the elevated levels of atmospheric carbon dioxide [CO2].
“Most CO2 from fossil fuels is emitted in the northern hemisphere and it takes at least [...]

BECAUSE the increase in the concentration of atmospheric carbon dioxide has correlated with an increase in the use of fossil fuels, causation has been assumed.
Tom Quirk has tested this assumption including through an analysis of the time delay between northern and southern hemisphere variations in carbon dioxide.  In a new paper in the journal Energy and Environment [...]

One of the most vexing things about climate change is the endless debate about temperatures. Did they rise, did they fall or were they pushed? At times it seems like a Monty Python sketch following either the Dead Parrot or the 5 or 10 Minute Argument… So began Part 1 of ‘A Note on Temperature [...]

One of the most vexing things about climate change is the endless debate about temperatures. Did they rise, did they fall or were they pushed? At times it seems like a Monty Python sketch following either the Dead Parrot or the 5 or 10 Minute Argument.
However it is possible to see some of the issues [...]

General Circulation Models (GCM) used to forecast the future evolution of the atmosphere do not properly cover many of the important features of the last fifty years. This raises serious questions about their ability to predict future climate development with a precision that will be of use to policy makers.
The following are a simple and [...]

The mining of uranium and the disposal of spent fuel are the largest components of the costs in the uranium fuel cycle.
The disposal of long-lived radioactive waste within Australia could be one of the single biggest contributions we can make to the safety of our region, and even the world.
Domestically, Australia produces about 45 cubic [...]
