In mid July 2016 Wendy and I took flight again to Europe. Those who follow these travel diaries will note that part of out trip last year was cut when Wendy's mum took ill. In particular we missed out on a planned trip to Romania and eastern Germany. This time our British sojourn would be interrupted for a few days by a side-trip to Copenhagen and Roskilde in Denmark.
1967 is in the news this week as it is 50 years since one of the few referendums, since the Federation of Australia in 1901, to successfully lead to an amendment to our Constitution. In this case it was to remove references to 'aboriginal natives' and 'aboriginal people'.
It has been widely claimed that these changes enabled Aboriginal Australians to vote for the first time but this is nonsense.
Yet it was ground breaking in other ways.
I originally wrote the paper, Issues Arising from the Greenhouse Hypothesis, in 1990 and do not see a need to revise it substantially. Some of the science is better defined and there have been some minor changes in some of the projections; but otherwise little has changed.
In the Introduction to the 2006 update to that paper I wrote:
Climate change has wide ranging implications... ranging from its impacts on agriculture (through drought, floods, water availability, land degradation and carbon credits) mining (by limiting markets for coal and minerals processing) manufacturing and transport (through energy costs) to property damage resulting from storms.
The issues are complex, ranging from disputes about the impact of human activities on global warming, to arguments about what should be done and the consequences of the various actions proposed.
