In October 2018 we travelled to Ireland. Later we would go on to England (the south coast and London) before travelling overland (and underwater) by rail to Belgium and then on to Berlin to visit our grandchildren there.
The island of Ireland is not very big, about a quarter as large again as Tasmania, with a population not much bigger than Sydney (4.75 million in the Republic of Ireland with another 1.85 million in Northern Ireland). So it's mainly rural and not very densely populated.
It was unusually warm for October in Europe, including Germany, and Ireland is a very pleasant part of the world, not unlike Tasmania, and in many ways familiar, due to a shared language and culture.
On the occasion of an afternoon tea to mark this significant milestone...

Hang on! Now I'm seventy? How did that happen?
| 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... |
Carbon Sequestration Source: Wikimedia Commons
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.
