Easter

 

 

 

Easter /'eestuh/. noun

  1. an annual Christian festival in commemoration of the resurrection of Jesus Christ, observed on the first Sunday after the full moon that occurs on or next after 21 March (the vernal equinox)

[Middle English ester, Old English eastre, originally, name of goddess; distantly related to Latin aurora dawn, Greek eos; related to east]

Macquarie Dictionary

 

I'm not very good with anniversaries so Easter might take me by surprise, were it not for the Moon - waxing gibbous last night.  Easter inconveniently moves about with the Moon, unlike Christmas.  And like Christmas, retailers give us plenty of advanced warning. For many weeks the chocolate bilbies have been back in the supermarket - along with the more traditional eggs and rabbits.

Carbon Capture and Storage

The following abbreviated paper is extracted from a longer, wider-ranging, paper with reference to energy policy in New South Wales and Australia, that was written in 2008. 
This extract relates solely to CCS.
The original paper that is critical of some 2008 policy initiatives intended to mitigate carbon dioxide emissions can still be read in full on this website: Read here...

This illustration shows the two principal categories of Carbon Capture and Storage (Carbon Sequestration) - methods of disposing of carbon dioxide (CO2) so that it doesn't enter the atmosphere.  Sequestering it underground is known as Geosequestration while artificially accelerating natural biological absorption is Biosequestration.

There is a third alternative of deep ocean sequestration but this is highly problematic as one of the adverse impacts of rising CO2 is ocean acidification - already impacting fisheries. 

This paper examines both Geosequestration and Biosequestration and concludes that while Biosequestration has longer term potential Geosequestration on sufficient scale to make a difference is impractical.
