Russia

In June 2013 we visited Russia.  Before that we had a couple of weeks in the UK while our frequent travel companions Craig and Sonia, together with Sonia's two Russian speaking cousins and their partners and two other couples, travelled from Beijing by the trans Siberian railway.  We all met up in Moscow and a day later joined our cruise ship.  The tour provided another three guided days in Moscow before setting off for a cruise along the Volga-Baltic Waterway to St Petersburg; through some 19 locks and across some very impressive lakes.

A Secret Agent

A crime fiction...

Chapter 1

Everywhere we look there is falling water. Down the track to the right is a lookout to the other side of the gorge, in Brazil, where the cliff faces are covered by maybe a kilometre of falling curtains in white windswept water. Here and there the curtains hang in gaps or are pushed aside by clumps of trees and bushes, like stagehands peeking out into a theatre before the performance.  

Carbon Capture and Storage

(Carbon Sequestration)

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.
