In April 2010 we travelled to the previous French territories of Cambodia and Vietnam: ‘French Indochina’, as they had been called when I started school; until 1954. Since then many things have changed. But of course, this has been a region of change for tens of thousands of years. Our trip ‘filled in’ areas of the map between our previous trips to India and China and did not disappoint. There is certainly a sense in which Indochina is a blend of China and India; with differences tangential to both. Both have recovered from recent conflicts of which there is still evidence everywhere, like the smell of gunpowder after fireworks.
On the morning of May1st 2016 I jumped, or rather slid, out of a plane over Wollongong at 14,000 feet.
It was a tandem jump, meaning that I had an instructor strapped to my back.
Striding Confidently Before Going Up
At that height the curvature of the earth is quite evident. There was an air-show underway at the airport we took off from and we were soon looking down on the planes of the RAAF Roulette aerobatic display team. They looked like little model aircraft flying in perfect formation.

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.
