In June 2021 Wendy and I, with our friends Craig and Sonia (see: India; Taiwan; JapanChina; and several countries in South America)  flew to Ayer's Rock where we hired a car for a short tour of Central Australia: Uluru - Alice Springs - Kings Canyon - back to Uluru. Around fifteen hundred kilometres - with side trips to the West MacDonnell Ranges; and so on.

How I miss Rio.  Rio de Janeiro the most stunningly picturesque city on Earth with its dark green mountains and generous bays, embelezado with broad white, sandy beaches.  Rio forever in my heart.   Rio my a minha pátria, my homeland, where I spent the most wonderful days of my life with linda, linda mãe, my beautiful, beautiful mother. Clambering up Corcovado Mountain together, to our favela amongst the trees.

Thinking back, I realise that she was not much older than I was, maybe fifteen years.  Who knows?

Her greatest gift to me was English.

Carbon Capture and Storage

 

 

(Carbon Sequestration)

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:

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.
