On the 17th February 2020 Wendy and I set sail on Queen Elizabeth on a two week cruise up to Papua New Guinea, returning to Sydney on 2nd March.

After a stop in Brisbane on the way the ship headed north to Rabaul, returning by:
Kiriwina Island; Milne Bay (Alotau); the Conflict Islands; and Cairns in far north Queensland
Sydney to Rabaul is around four thousand kilometres
In the seventies I spent some time travelling around Denmark visiting geographically diverse relatives but in a couple of days there was no time to repeat that, so this was to be a quick trip to two places that I remembered as standing out in 1970's: Copenhagen and Roskilde.
An increasing number of Danes are my progressively distant cousins by virtue of my great aunt marrying a Dane, thus contributing my mother's grandparent's DNA to the extended family in Denmark. As a result, these Danes are my children's cousins too.
Denmark is a relatively small but wealthy country in which people share a common language and thus similar values, like an enthusiasm for subsidising wind power and shunning nuclear energy, except as an import from Germany, Sweden and France.
They also like all things cultural and historical and to judge by the museums and cultural activities many take pride in the Danish Vikings who were amongst those who contributed to my aforementioned DNA, way back. My Danish great uncle liked to listen to Geordies on the buses in Newcastle speaking Tyneside, as he discovered many words in common with Danish thanks to those Danes who had settled in the Tyne valley.
Nevertheless, compared to Australia or the US or even many other European countries, Denmark is remarkably monocultural. A social scientist I listened to last year made the point that the sense of community, that a single language and culture confers, creates a sense of extended family. This allows the Scandinavian countries to maintain very generous social welfare, supported by some of the highest tax rates in the world, yet to be sufficiently productive and hence consumptive per capita, to maintain among the highest material standards of living in the world.
This morning Miranda had an inspiration - real candles! We'll have real candles - made from real beeswax and scented with real bergamot for my final party as a celebration of my life and my death. This brief candle indeed!
In other circumstances she would be turning 60 next birthday. With her classic figure, clear skin and dark lustrous hair, by the standards of last century she looks half her age, barely thirty, the result of a good education; modern scientific and medical knowledge; a healthy diet and lifestyle and the elimination of inherited diseases before the ban on such medical interventions.
It's ironical that except as a result of accidents, skiing, rock climbing, paragliding and so on, Miranda's seldom had need of a doctor. She's a beneficiary of (once legal) genetic selection and unlike some people she's never had to resort to an illegal back-yard operation to extend her life.

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.
